It was on this day back in 2011 that Atlantis took off from Launch Complex 39A at NASA's Kennedy Space Center in Florida...beginning mission STS-135 to the International Space Station that lasted 12 days, 18 hours, 28 minutes and 50 seconds, and successfully concluded the 30-year space shuttle program. 15 years later, this anniversary is marked by humans finally venturing to the Moon once more on last April's Artemis 2 mission...and NASA gearing up for Artemis 3, an Earth-orbiting test flight that will pave the way for astronauts returning to the lunar surface on Artemis 4.

The time period between 2011 and 2020 (when SpaceX's Demo-2 flight resumed crewed launches from U.S. soil for the first time since STS-135) was marked by delays and uncertainty in America's human spaceflight program. But as of 2026, things are absolutely picking up with mankind moving ever so closer to maintaining a sustainable presence at the Moon, and finally, sending humanity on a much-awaited voyage to Mars. The future of space exploration has never been more promising than this!

NASA Marches Toward Artemis III Mission in 2027, Names Crew Members (News Release)

Taking another step towards one of the most complex human spaceflight missions in recent history, NASA on Tuesday provided new Artemis III details and announced the four prime crew members and a backup for the test flight. The mission will undertake a series of challenging tests in Earth orbit in 2027, essential for Artemis IV, the first planned crewed mission to the lunar South Pole in 2028.

During Artemis III, the agency’s SLS (Space Launch System) rocket will launch the Orion spacecraft and its crew from NASA’s Kennedy Space Center in Florida to low-Earth orbit. After Orion systems checkouts, the spacecraft will, for the first time, demonstrate rendezvous and docking capabilities with test versions from one, or both, American commercial Human Landing Systems in development by Blue Origin and SpaceX. This highly-choreographed mission includes a dramatic multi-launch campaign of the world’s most powerful rockets, testing integrated hardware between Orion and the landers, including system interfaces, software, propulsion and communications.

Crew assignments are as follows:

-- NASA astronaut Randy Bresnik, commander
-- ESA (European Space Agency) astronaut Luca Parmitano, pilot
-- NASA astronaut Andre Douglas, mission specialist
-- NASA astronaut Frank Rubio, mission specialist

As part of Tuesday’s event, NASA astronaut Bob Hines was named as a backup crew member. The crew will begin training immediately on Orion spacecraft systems, as well as assist in the development and operations of the test versions of Blue Origin and SpaceX landers.

“Today we take another bold step in humanity’s return to the Moon, building on the extraordinary foundation laid by the Artemis II astronauts,” said NASA Administrator Jared Isaacman. “Their achievements reignited global excitement for exploration, and now they pass the torch to the Artemis III team, Randy, Luca, Frank and Andre. Artemis III will demonstrate the power of American innovation and international partnership as we test complex rendezvous and docking operations and advance the technologies that will one day carry us deeper into the Solar System.

“This mission will require the most awe-inspiring coordination of heavy-lift rocket launches in history, drawing on the talent and capability of teams across government and the spaceflight community. The Artemis III astronauts, alongside ESA and our international partners, and the tens of thousands of the best and brightest across the agency and industry, are ushering in a new Golden Age of exploration carrying forward the hopes and dreams of the next generation just as the Apollo astronauts did for so many of us.”

This is also the first time that an ESA astronaut has been assigned to an Artemis mission.

“Artemis III will push the boundaries of spacecraft operations in orbit. Luca’s assignment as pilot reflects the depth of European expertise in human spaceflight and draws on his extensive operational experience in high-pressure situations,” said Josef Aschbacher, ESA’s director general. “At the same time, ESA’s European Service Module will once again provide the critical capabilities that power Orion, demonstrating Europe’s enduring role at the very heart of the Artemis program. The news out of Houston today is a powerful recognition of ESA’s role in enabling humanity’s return to the Moon – and a key advancement in our partnership with NASA. Europeans can take pride in being part of this exciting journey.”

Mission progress

NASA and its partners are making progress preparing for the test flight.

Engineers will connect the Orion crew module and service module this summer and integrate the spacecraft’s docking system, which will fly for the first time. Heat shield testing continues with individual blocks having undergone ultra-sonic inspections and installation onto the heat shield structure.

Rocket processing is also well underway. Technicians for SLS are integrating the engine section to the rest of the core stage ahead of installing the four RS-25 engines this summer. With all solid rocket booster segments now at NASA Kennedy and Mobile Launcher refurbishments on track, rocket stacking is also scheduled to begin this summer.

NASA continues design and fabrication of a spacer that will replace the upper stage on Artemis III.

Blue Origin is developing a crewed lunar version of the company’s Blue Moon lander, while SpaceX is developing a crewed lunar lander version of the company’s Starship, with both companies building test articles for Artemis III. NASA is supporting both lander providers hands-on throughout design, development, testing and evaluation, including sharing agency expertise and capabilities gained from previous missions.

In addition to status updates from NASA and both commercial partners, the agency discussed details during the event about the planned operations for Artemis III, which will support an increased mission cadence, ramp up production, and drive supply chain improvements for the Artemis program.

The Artemis III mission builds on the successful Artemis II flight completed in April and will help the agency prepare to send the first astronauts, Americans, to Mars.

Artemis III includes launching the world’s most powerful rockets in short order. Blue Origin’s lander pathfinder, which is able to stay in orbit for multiple weeks, will launch first and await the crew. NASA will send the astronauts aboard Orion by SLS to orbit Earth, before rendezvousing in space with the company’s lander test article and spending about two days docked together for tests and technology demonstrations, including entering the lander.

After completing docked operations with Blue Origin, Orion will detach and await Starship. SpaceX’s Starship pathfinder will launch and meet up with Orion to spend about a day connected for checkouts and testing. After that, Orion and its crew will undock and return home, safely splashing down in the Pacific Ocean where a team from the U.S. Navy and NASA will recover the astronauts.

In total, the crew is expected to remain in space for about two weeks, with exact mission length to be determined in real-time based on launch, rendezvous and docked operations.

NASA Outlines Preliminary Artemis III Mission Plans (News Release)

NASA is moving quickly to define next year’s Artemis III mission in Earth orbit, a crewed flight that will test rendezvous and docking capabilities between the agency’s Orion spacecraft and commercial landers from Blue Origin and SpaceX. Since a February announcement adding an Artemis mission ahead of crewed landing missions to the Moon’s South Pole region, engineers have been evaluating mission profile options and operational considerations for Artemis III to ensure that the test flight helps the agency and its partners reduce risk ahead of the next Americans landing on the Moon during Artemis IV.

“While this is a mission to Earth orbit, it is an important stepping stone to successfully landing on the Moon with Artemis IV. Artemis III is one of the most highly complex missions NASA has undertaken,” said Jeremy Parsons, Moon to Mars acting assistant deputy administrator, NASA’s Exploration Systems Development Mission Directorate in Washington. “For the first time, NASA will coordinate a launch campaign involving multiple spacecraft integrating new capabilities into Artemis operations. We’re integrating more partners and interrelated operations into this mission by design, which will help us learn how Orion, the crew, and ground teams all interact together with hardware and teams from both lander providers before we send astronauts to the Moon’s surface and build a Moon Base there.”

The mission is planned to carry out a series of objectives designed to demonstrate critical systems needed for a future lunar landing. During the Artemis III mission, the SLS (Space Launch System) rocket will launch the Orion spacecraft from NASA’s Kennedy Space Center in Florida with four crew members. Instead of using the interim cryogenic propulsion stage as the upper stage of the rocket, NASA will use a “spacer,” a representation of the mass and overall dimensions of an upper stage but without propulsive capabilities.

The spacer will maintain the same overall dimensions and interface connection points as the upper stage between the Orion stage adapter and launch vehicle stage adapter.

Design and fabrication activities for the spacer are progressing rapidly at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Material for the barrel section and the upper and lower rings is currently being machined at Marshall in preparation for upcoming welding operations.

After the rocket delivers Orion to orbit, the spacecraft’s European-built service module will provide propulsion to circularize Orion’s orbit around the planet in low-Earth orbit. This orbit increases overall mission success by allowing more launch opportunities for each element as compared to a lunar mission — SLS carrying Orion and its crew, SpaceX’s Starship human landing system pathfinder, and Blue Origin’s Blue Moon Mark 2 human landing system pathfinder.

Informed by Blue Origin and SpaceX capabilities, NASA is also defining the concept of operations for the mission. While some decisions are yet to be determined, astronauts could potentially enter at least one lander test article.

The crew will spend more time aboard Orion than during Artemis II, further advancing the evaluation of life support systems, and for the first time will demonstrate the docking system performance. The mission will inform lander rendezvous and habitation concepts and mission operations in preparation for future surface missions. The agency also plans to test an upgraded heat shield during Orion’s return to Earth to enable more flexible and robust reentry profiles for future missions.

Over the coming weeks, NASA will continue to refine specific plans for the flight, including a timeline for identifying astronauts to train for mission operations, options to evaluate Axiom’s AxEMU spacesuit lander interfaces ahead of lunar surface missions, mission duration, and potential science operations for the flight. NASA has asked for industry input on potential solutions to improve the communications with the ground during the mission since the Deep Space Network will not be used. The agency is also seeking both international and domestic interest in potentially flying CubeSats to deploy in Earth orbit, and may share other opportunities as the concept of operations for the mission is further defined.

As part of the Golden Age of innovation and exploration, NASA will send Artemis astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, establish an enduring human presence on the lunar surface, and to build on our foundation for the first crewed missions to Mars.

NASA’s Artemis III Moon Rocket Hardware Arrives, Artemis II Capsule Returns to Kennedy (News Release)

On the heels of a successful Artemis II test flight, teams at NASA’s Kennedy Space Center in Florida are pressing forward for the next Artemis mission. Technicians maneuvered NASA’s massive core stage of the SLS (Space Launch System) rocket inside the agency’s Vehicle Assembly Building (VAB) at NASA Kennedy on April 28 in preparation for Artemis III, as the Artemis II crew module arrived back at Kennedy for post-flight analysis.

The Artemis III core stage will be placed horizontally in the transfer aisle of the VAB before being lifted into High Bay 2, where it will be connected to the engine section and its boat-tail, which were integrated in August 2025. At 212 feet tall when fully assembled, the core stage houses two propellant tanks that collectively hold more than 733,000 gallons of super-chilled liquid propellant to fuel four RS-25 engines, as well as the flight computers, or avionics, that act as the brains of the rocket to control flight during ascent. This marks the first time core stage assembly operations are taking place at NASA Kennedy.

Booster Motor Segments for Artemis III Processing

Other SLS hardware for Artemis III is arriving in Florida. The first shipment of booster motor segments for the flight arrived at Kennedy on April 13. These components will form the twin solid rocket boosters for SLS, which generate more than 75% of the rocket’s thrust at liftoff.

A second shipment of booster motor segments is expected this summer.

Shipped by rail across eight states in specialized transporters, the segments were manufactured by Northrop Grumman in Utah before making their journey to the spaceport. Teams are now processing the hardware inside Kennedy’s Rotation, Processing and Surge Facility, where each segment will be inspected and prepared for integration.

Once ready, the motor segments will be moved to the VAB and stacked with forward and aft assemblies to form the towering, 17-story-tall boosters. Working together with the SLS core stage and its four RS-25 engines, the boosters will help produce 8.8 million pounds of thrust—powering Artemis III and future missions as NASA continues its campaign of lunar exploration.

Artemis II Orion Arrives at Kennedy

Arriving on the opposite side of the spaceport after carrying NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen around the Moon and returning them safely to Earth, Artemis II's Orion spacecraft Integrity arrived back at NASA Kennedy’s Multi-Payload Processing Facility.

Now at Kennedy, technicians will begin de-servicing operations on Integrity. This includes removing payloads from the crew module, removing avionics boxes for reuse, and retrieving data on the spacecraft to better understand how it performed to inform procedures and plans for future Artemis missions. Integrity’s heat shield and other elements will be removed for extensive analysis, and remaining hazards such as excess propellant will be offloaded.

While detailed Artemis II post-flight assessments are underway, engineers are completing major functional testing of the Artemis III Orion crew module at NASA Kennedy before joining it with its service module later this summer. All 186 Avcoat blocks for its upgraded heat shield have been installed, cured and inspected. Teams also completed thermal cycle testing and ultrasonic inspections of the heat shield.

The Artemis III Orion service module has successfully undergone thermal cycle testing, deployment checks of all four solar array wings, and installation of the adapter cone that connects Orion to the SLS rocket. NASA plans to integrate the crew and service modules with the launch abort system later this year.

Next year’s Artemis III mission will launch astronauts to Earth’s orbit aboard the Orion spacecraft on top of SLS to test rendezvous and docking capabilities between Orion and commercial spacecraft needed to land Artemis IV astronauts on the Moon in 2028.

NASA Rolls Out Artemis III Moon Rocket Core Stage (News Release)

Following the recent successful test flight of NASA’s Artemis II mission around the Moon, NASA rolled out the core stage, or the largest section, of the agency’s SLS (Space Launch System) rocket that will launch the crewed Artemis III mission in 2027. The stage departed from the agency’s Michoud Assembly Facility in New Orleans on Monday for shipment to NASA’s Kennedy Space Center in Florida, marking key progress on the path to the agency’s first crewed lunar landing mission to the Moon under the Artemis program in two years.

Using highly-specialized transporters, engineers maneuvered the top four-fifths of the SLS core stage, the section containing the liquid hydrogen tank, liquid oxygen tank, intertank and forward skirt, from inside NASA Michoud to the agency’s Pegasus barge for delivery to NASA Kennedy. After arrival, teams will complete the stage outfitting and vertical integration, and the agency’s Exploration Ground Systems Program will stack the rocket’s components in preparation for launch.

“Seeing this SLS rocket hardware roll out is a powerful reminder of our progress toward returning humans to the lunar surface,” said Lori Glaze, acting associate administrator, Exploration Systems Development Mission Directorate at NASA Headquarters in Washington. “This is the backbone of Artemis III. As it heads to Florida for final integration, we are one step closer to testing the critical capabilities needed to land Americans on the Moon, and ultimately, paving the way for our first crewed missions to Mars.”

At 212 feet tall, the completed core stage will consist of the top four fifths of the rocket combined with its engine section. The top four-fifths include the two propellant tanks that collectively hold more than 733,000 gallons of super-chilled liquid propellant to fuel four RS-25 engines. During launch and flight, the fully-integrated stage will operate for more than eight minutes, producing more than 2 million pounds of thrust to propel astronauts inside NASA’s Orion spacecraft into orbit.

Building, assembling and transporting the core stage is a collaborative process for two of NASA’s prime contractors, Boeing and L3Harris Technologies. Boeing is responsible for the overall design and assembly of the core stage, and L3Harris manufactures the rocket’s RS-25 engines. Recent announcements by NASA Administrator Jared Isaacman enabled the agency to standardize the SLS configuration, streamline operations, and optimize production to accelerate the Artemis program.

Next year’s Artemis III mission will launch astronauts to Earth’s orbit aboard the Orion spacecraft on top of SLS to test rendezvous and docking capabilities between Orion and commercial spacecraft needed to land Artemis IV astronauts on the Moon in 2028. NASA’s SLS is the only rocket capable of sending Orion, astronauts and supplies to the Moon in a single launch.

As part of the Golden Age of innovation and exploration, NASA will send Artemis astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, establish an enduring human presence on the lunar surface, and to build on our foundation for the first crewed missions to Mars.

NASA Unveils Initiatives to Achieve America’s National Space Policy (News Release)

As part of its Ignition event on Tuesday, NASA announced a series of transformative agencywide initiatives designed to achieve the president's National Space Policy and advance American leadership in space. These actions reflect the urgency of the moment, but also the tremendous opportunity ahead for world-changing science and discovery.

“NASA is committed to achieving the near‑impossible once again, to build a Moon base, establish an enduring presence, and do the other things needed to ensure American leadership in space. This is why it is essential we leave an event like Ignition with complete alignment on the national imperative that is our collective mission. The clock is running in this great‑power competition, and success or failure will be measured in months, not years,” said NASA Administrator Jared Isaacman.

“If we concentrate NASA’s extraordinary resources on the objectives of the National Space Policy, clear away needless obstacles that impede progress, and unleash the workforce and industrial might of our nation and partners, then returning to the Moon and building a base will seem pale in comparison to what we will be capable of accomplishing in the years ahead.”

NASA Associate Administrator Amit Kshatriya said, “Today we are aligning NASA around the mission. On the Moon, we are shifting to a focused, phased architecture that builds capability landing by landing, incrementally, and in alignment with our industrial and international partners. In low-Earth orbit (LEO), we are recognizing where the market is and where it isn’t, recognizing the incredible value of the International Space Station, and building a transition that builds a competitive commercial ecosystem rather than forcing a single outcome the market cannot support.

"In our science missions, we are opening the lunar surface to researchers and students nationwide, and with Space Reactor‑1 Freedom, we are finally putting nuclear propulsion on a trajectory out of the laboratory and into deep space. And this is all possible by investing in our people, bringing critical skills back into the agency, putting our teams where the machines are being built, and creating real pathways for the next generation of NASA leaders. Our workforce is the jewel of NASA, and from their leaders, they need clear mission goals, the tools to execute, and to get out of their way. This is what Ignition is about.”

Going back to the Moon

The announcements build on recent updates to the Artemis program, including standardizing the SLS (Space Launch System) rocket configuration, adding an additional mission in 2027, and undertaking at least one surface landing every year thereafter. Under this previously updated architecture, Artemis III – scheduled for 2027 – will focus on testing integrated systems and operational capabilities in Earth orbit in advance of the Artemis IV lunar landing.

Looking beyond Artemis V, NASA announced on March 24 that it will begin to incorporate more commercially-procured and reusable hardware to undertake frequent and affordable crewed missions to the lunar surface, initially targeting landings every six months, with the potential to increase cadence as capabilities mature.

To achieve an enduring human presence on the Moon, NASA also announced a phased approach to building a lunar base. As part of this strategy, the agency intends to pause Gateway in its current form and shift focus to infrastructure that enables sustained surface operations. Despite challenges with some existing hardware, the agency will repurpose applicable equipment and leverage international partner commitments to support these objectives.

In the coming days, NASA will release Requests for Information (RFIs) and draft Requests for Proposals (RFPs) to ensure continued progress in meeting national objectives.

Building the Moon Base

NASA’s plan for establishing a sustained lunar presence will roll out in three deliberate phases.

-- Phase One: Build, Test, Learn
NASA shifts from bespoke, infrequent missions to a repeatable, modular approach. Through CLPS (Commercial Lunar Payload Services) deliveries and the LTV (Lunar Terrain Vehicle) program, the agency will increase the tempo of lunar activity, sending rovers, instruments and technology demonstrations that advance mobility, power generation (including radioisotope heater units and radioisotope thermoelectric generators), communications, navigation, surface operations, and a wide range of scientific investigations.

-- Phase Two: Establish Early Infrastructure
With lessons from early missions in hand, NASA moves toward semi‑habitable infrastructure and regular logistics. This phase supports recurring astronaut operations on the surface and incorporates major international contributions, including JAXA’s (Japan Aerospace Exploration Agency) pressurized rover, and potentially other partner scientific payloads, rovers, and infrastructure/transportation capabilities.

--Phase Three: Enable Long‑Duration Human Presence
As cargo‑capable Human Landing Systems (HLS) come online, NASA will deliver heavier infrastructure needed for a continuous human foothold on the Moon, marking the transition from periodic expeditions to a permanent lunar base. This will include ASI’s (Italian Space Agency) Multi-purpose Habitats (MPH), CSA’s (Canadian Space Agency) Lunar Utility Vehicle, and opportunities for additional contributions in habitation, surface mobility and logistics.

Ensuring American presence in low-Earth orbit

While building a sustainable lunar architecture, NASA is also reaffirming its commitment to low-Earth orbit. For more than two decades, the International Space Station has served as a world‑class orbital laboratory, enabling more than 4,000 research investigations, supporting more than 5,000 researchers, and hosting visitors from 26 countries. The space station required 37 shuttle flights, 160 spacewalks, two decades, and more than $100 billion to design, develop and build.

The orbital laboratory cannot operate indefinitely. The transition to commercial stations must be thoughtful, deliberate and structured to support long‑term industry success.

NASA is introducing and seeking industry feedback on an additional LEO strategy that preserves all current pathways while adding a phased, International Space Station‑anchored approach to avoid any gap in U.S. human presence and mature a robust commercial ecosystem. Under this alternative approach, NASA would procure a government‑owned Core Module that attaches to the space station, followed by commercial modules that are validated using International Space Station capabilities and later detach into free flight. After maturing technical and operational capabilities and market demand is realized, the stations would detach and NASA would be one of many customers purchasing commercial services.

To stimulate the orbital economy, NASA would expand industry opportunities, including private astronaut missions, commander seat sales, joint missions, multiple module competitions, and prize‑based awards.

An industry RFI opens on Wednesday, March 25, to inform partnership structures, financing, and risk mitigation.

Advancing world-changing discovery with current, developing science missions

In a Golden Age of exploration and discovery, NASA takes full advantage of every opportunity to get science into space. The James Webb Space Telescope continues to transform our understanding of the early Universe, Parker Solar Probe has flown through the atmosphere of the Sun, NASA has shown that it can defend the planet by deflecting asteroids, and Earth science data is used extensively by American companies, U.S. agriculture, and disaster relief. On the International Space Station, NASA is conducting groundbreaking experiments in quantum science.

Future opportunities will advance U.S. leadership in space science. The Nancy Grace Roman Space Telescope, launching as early as this fall, will advance our understanding of dark energy, and has created a new standard for the management of large science missions. Dragonfly will launch a nuclear-powered octocopter in 2028, arriving at Saturn’s moon Titan in 2034 to explore its complex, organic-rich environment.

In 2028, NASA will launch and deliver ESA’s (European Space Agency) Rosalind Franklin Rover to Mars, with NASA’s contributed mass spectrometer for the Mars Organic Molecule Analyzer (MOMA) instrument, which may result in the most advanced detection and analysis of organic matter ever conducted on Mars. A new Earth science mission launching next year will measure for the first time the evolution of the dynamics within convective storms to improve the prediction of extreme weather events up to six hours before the storm occurs.

The agency detailed how advancements in lunar science will also be afforded by the build out of the Moon Base and underpin future Moon and Mars exploration. With an accelerated CLPS cadence, targeting up to 30 robotic landings starting in 2027, NASA is expediting delivery of science and technology to the lunar surface. There will be many opportunities for payload delivery including rovers, hoppers and drones with contributions welcomed from industry, academia and international partners.

Near-term payloads include the VIPER rover and the LuSEE‑Night mission. An RFI will be released on March 24 that calls for payloads capable of supporting NASA’s science and technology goals for additional 2027 and 2028 flights. It will enable students and researchers across the country to work on scientific instruments for use on the surface of the Moon in the years ahead.

This RFI will also solicit payloads incorporated on future missions to Mars including the Mars Telecom Network (MTN) and a nuclear technology demonstration mission.

The agency intends to partner with philanthropic and privately-funded research organizations with shared objectives in space science.

Other RFIs released on March 24 will strengthen “Science as a Service” partnerships and commercial capabilities, allowing NASA to streamline legacy operations and focus investment on the transformational missions that only the agency can lead.

Finally, NASA will unveil a previously unseen pair of images from the James Webb and Hubble Space Telescopes. These images show the planet Saturn in unprecedented detail in both infrared and visible wavelengths.

America underway on nuclear power in space

In addition to these scientific missions, after decades of study and in response to the National Space Policy, NASA announced a major step forward in bringing nuclear power and propulsion from the lab to space.

NASA will launch the Space Reactor‑1 Freedom, the first nuclear-powered interplanetary spacecraft, to Mars before the end of 2028, demonstrating advanced nuclear electric propulsion in deep space. Nuclear electric propulsion provides an extraordinary capability for efficient mass transport in deep space and enables high power missions beyond Jupiter where solar arrays are not effective.

When SR-1 Freedom reaches Mars, it will deploy the Skyfall payload of Ingenuity‑class helicopters to continue exploring the Red Planet. SR-1 Freedom will establish flight heritage nuclear hardware, set regulatory and launch precedent, and activate the industrial base for future fission power systems across propulsion, surface, and long‑duration missions. NASA and its U.S. Department of Energy partner will unlock the capabilities required for sustained exploration beyond the Moon and eventual journeys to Mars and the outer Solar System.

None of these endeavors can succeed without the NASA workforce. As previously announced, the agency is rebuilding its core competencies, converting thousands of contractor positions to civil service, and restoring the engineering, technical and operational strengths expected of the world’s premier space organization.

NASA is expanding opportunities for interns and early‑career professionals and, in partnership with the U.S. Office of Personnel Management and NASA Force, is creating new pathways for experienced industry talent to serve through term‑based appointments. The agency is also seeking to open opportunities for NASA employees to gain valuable experience working within the most technologically-advanced space industry in history.

The changes announced on March 24 will be implemented during the coming months, with teams agencywide ensuring a smooth transition while advancing key programs and partnerships.

NASA will embed subject‑matter experts across the supply chain – at every major vendor, subcontractor and critical‑path component – to challenge assumptions, solve problems, accelerate production, and help ensure that the right outcomes are achieved.

Through these reforms, NASA is strengthening its ability to deliver on the president’s National Space Policy and ensure continued American superiority in space.

NASA Adds Mission to Artemis Lunar Program, Updates Architecture (News Release)

As part of a Golden Age of exploration and discovery, NASA announced on Friday that the agency is increasing its cadence of missions under the Artemis program to achieve the national objective of returning American astronauts to the Moon and establishing an enduring presence. This includes standardizing vehicle configuration, adding an additional mission in 2027, and undertaking at least one surface landing every year thereafter.

As teams prepare to launch Artemis II in the weeks ahead, the Artemis III mission, now in 2027, will be designed to test out systems and operational capabilities in low-Earth orbit to prepare for an Artemis IV landing in 2028. This new mission will endeavor to include a rendezvous and docking with one or both commercial landers from SpaceX and Blue Origin, in-space tests of the docked vehicles, integrated checkout of life support, communications and propulsion systems, as well as tests of the new Extravehicular Activity (xEVA) suits. NASA will further define this test flight after completing detailed reviews between NASA and our industry partners.

The agency will share the specific objectives for the updated Artemis III mission in the near future.

NASA’s recently announced workforce directive is a key factor in enabling this acceleration. NASA will rebuild core competencies in the civil servant workforce including more in-house and side-by-side development work with our Artemis partners, enabling a safer, more reliable, and faster launch cadence.

“NASA must standardize its approach, increase flight rate safely, and execute on the President’s national space policy. With credible competition from our greatest geopolitical adversary increasing by the day, we need to move faster, eliminate delays, and achieve our objectives,” said NASA Administrator Jared Isaacman. “Standardizing vehicle configuration, increasing flight rate and progressing through objectives in a logical, phased approach, is how we achieved the near-impossible in 1969 and it is how we will do it again.”

“After successful completion of the Artemis I flight test, the upcoming Artemis II flight test, and the new, more robust test approach to Artemis III, it is needlessly complicated to alter the configuration of the SLS and Orion stack to undertake subsequent Artemis missions,” said NASA Associate Administrator Amit Kshatriya. “There is too much learning left on the table and too much development and production risk in front of us. Instead, we want to keep testing like we fly and have flown. We are looking back to the wisdom of the folks that designed Apollo.

"The entire sequence of Artemis flights needs to represent a step-by-step build-up of capability, with each step bringing us closer to our ability to perform the landing missions. Each step needs to be big enough to make progress, but not so big that we take unnecessary risk given previous learnings. Therefore, we want to fly the landing missions in as close to the same Earth ascent configuration as possible – this means using an upper stage and pad systems in as close to the ‘Block 1’ configuration as possible.

"We will work with our partners that have been developing the evolved block configuration of these systems to take proper actions to align their efforts towards this goal and announce the details of those changes once they are finalized. We will take a similar approach to in-space, landing and surface EVA operations as well, as we evolve the mission sequence in the spirit of the Apollo mindset, which was obsessed with system reliability and crew safety as the keys to mission success.”

“Boeing is a proud partner to the Artemis mission and our team is honored to contribute to NASA’s vision for American space leadership,” said Steve Parker, Boeing Defense, Space & Security president and CEO. “The SLS core stage remains the world’s most powerful rocket stage, and the only one that can carry American astronauts directly to the Moon and beyond in a single launch. As NASA lays out an accelerated launch schedule, our workforce and supply chain are prepared to meet the increased production needs. With a rocket designed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, built at America’s rocket factory at NASA’s Michoud Assembly Facility in New Orleans, and integrated at NASA’s Kennedy Space Center in Florida, we are ready to meet the increased demand.”

The announcement came during a news conference at NASA Kennedy where leaders also discussed the status of the Artemis II mission. NASA rolled the SLS and Orion spacecraft to the Vehicle Assembly Building (VAB) on February 25 for repairs ahead of the next launch opportunities for the test flight in April.

Once the Artemis II hardware was back in the VAB, teams immediately began work on the helium issue discovered on the Interim Cryogenic Propulsion Stage and prepared for several actions including replacing batteries in the flight termination system, end-to-end testing for range safety requirements, and more.

“I’m grateful to Administrator Isaacman for taking this bold step and moving quickly to assure we have the support and resources needed to launch Artemis astronauts to the Moon every year,” said Lori Glaze, acting associate administrator for Exploration Systems Development Mission Directorate at NASA Headquarters in Washington. “Our team is up to the challenge of a successful Artemis II mission, and soon thereafter, enabling a more frequent cadence of Moon missions.”

NASA Selects 2 Instruments for Artemis IV Lunar Surface Science (News Release)

NASA has selected two science instruments designed for astronauts to deploy on the surface of the Moon during the Artemis IV mission to the lunar south polar region. The instruments will improve our knowledge of the lunar environment to support NASA’s further exploration of the Moon and beyond to Mars.

“The Apollo Era taught us that the further humanity is from Earth, the more dependent we are on science to protect and sustain human life on other planets,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “By deploying these two science instruments on the lunar surface, our proving ground, NASA is leading the world in the creation of humanity’s interplanetary survival guide to ensure the health and safety of our spacecraft and human explorers as we begin our epic journey back to the Moon and onward to Mars.”

After his voyage to the Moon’s surface during Apollo 17, astronaut Gene Cernan acknowledged the challenge that lunar dust presents to long-term lunar exploration. Moon dust sticks to everything it touches and is very abrasive. The knowledge gained from the DUSTER (DUst and plaSma environmenT survEyoR) investigation will help mitigate hazards to human health and exploration.

Consisting of a set of instruments mounted on a small autonomous rover, DUSTER will characterize dust and plasma around the landing site.

These measurements will advance understanding of the Moon’s natural dust and plasma environment and how that environment responds to human presence, including any disturbance during crew exploration activities and lander liftoff. The DUSTER instrument suite is led by Xu Wang of the University of Colorado Boulder. The contract is for $24.8 million over a period of three years.

Data from the SPSS (South Pole Seismic Station) will enable scientists to characterize the lunar interior structure to better understand the geologic processes that affect planetary bodies. The seismometer will help determine the current rate at which the Moon is struck by meteorite impacts, monitor the real-time seismic environment and how it can affect operations for astronauts, and determine properties of the Moon’s deep interior. The crew will additionally perform an active-source experiment using a “thumper” that creates seismic energy to survey the shallow structure around the landing site.

The SPSS instrument is led by Mark Panning of NASA’s Jet Propulsion Laboratory in Southern California. The award is for $25 million over a period of three years.

"These two scientific investigations will be emplaced by human explorers on the Moon to achieve science goals that have been identified as strategically important by both NASA and the larger scientific community", said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate at NASA Headquarters. “We are excited to integrate these instrument teams into the Artemis IV Science Team.”

The two payloads were selected for further development to fly on Artemis IV; however, final manifesting decisions about the mission will be determined at a later date.

Through Artemis, NASA will address high-priority science questions, focusing on those that are best accomplished by on-site human explorers on and around the Moon and by using the unique attributes of the lunar environment, aided by robotic surface and orbiting systems. The Artemis missions will send astronauts to explore the Moon for scientific discovery, economic benefits and build the foundation for the first crewed missions to Mars.

Fourth Liquid Hydrogen Tank for NASA’s Space Launch System Rocket Assembled (Photo Release)

Teams at NASA’s Michoud Assembly Facility in New Orleans lift the 130-foot-tall liquid hydrogen tank off the vertical assembly center on November 14. This is the fourth liquid hydrogen tank manufactured at the facility for the agency’s SLS (Space Launch System) rocket. The completed tank will be loaded into a production cell for technicians to remove the lift tool, perform dimensional scans, and then install brackets, which will allow the move crew to break the tank over from a vertical to horizontal configuration.

The propellant tank is one of five major elements that make up the 212-foot-tall rocket stage. The core stage, along with its four RS-25 engines, produce more than two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts and supplies beyond Earth’s orbit and to the lunar surface for Artemis.

L3Harris Successfully Tests Second RS-25 Engine for Artemis V (Press Release)

STENNIS SPACE CENTER, Miss. — NASA and L3Harris Technologies (NYSE: LHX) have successfully test-fired the second RS-25 engine that will support the core stage of the Space Launch System (SLS) rocket for NASA’s Artemis V mission.

L3Harris’ RS-25 rocket engines are critical to the Artemis program’s success, with four RS-25s powering every SLS rocket, enabling the U.S. to help establish a sustainable presence on the Moon and prepare for future missions to Mars.

“As we approach America’s 250th anniversary next year, it’s fitting that we’re advancing the Artemis program that embodies the pioneering spirit of our nation,” said Kristin Houston, President, Space Propulsion and Power Systems, Aerojet Rocketdyne, L3Harris. “By leveraging advanced manufacturing techniques, we’re delivering engines that are more cost effective while maintaining the power and reliability needed to propel Artemis missions to the Moon and beyond.”

NASA conducted the test at its Stennis Space Center, which demonstrated the engine’s performance and reliability during a 500-second firing that reached 111% of its rated power level. This test marked the second flight-ready RS-25 engine produced using modern manufacturing techniques, including 3D printing, which reduce production costs by 30% compared to earlier RS-25 engines that powered the space shuttle.

The first four Artemis missions use upgraded RS-25 engines originally designed for the space shuttle program, while the fifth mission will debut the newly-produced RS-25 engines.
