NASA’s Artemis II Rocket Arrives at Launch Complex 39B (News Release)

At 11:21 a.m. EDT on Friday, March 20, NASA’s Artemis II SLS (Space Launch System) rocket and Orion spacecraft arrived at Launch Complex (LC)-39B after an 11-hour journey from the Vehicle Assembly Building at the agency’s Kennedy Space Center in Florida.

NASA’s Crawler-Transporter 2 began its 4-mile trek with the integrated SLS and Orion stacked on top of the Mobile Launcher at 12:20 a.m. EDT. Moving at a maximum speed of just 0.82 mph, the crawler carried the 322-foot-tall Moon rocket and spacecraft slowly and steadily toward the pad.

Now that the rocket is at LC-39B, NASA teams are gearing up for the final stretch of prelaunch preparations ahead of launch as soon as Wednesday, April 1. The early April launch window includes opportunities through Monday, April 6.

Artemis II Commander Reid Wiseman, Pilot Victor Glover and Mission Specialist Christina Koch of NASA, along with CSA’s (Canadian Space Agency) Mission Specialist Jeremy Hansen will embark on a 10-day journey around the Moon and back.

As part of a Golden Age of innovation and exploration, Artemis II is another step towards new U.S.-crewed missions to the Moon’s surface, leading to a sustained presence on the Moon that will help the agency prepare to send astronauts to Mars.

Artemis II Moon Rocket Heads Back to Launch Pad (News Release)

NASA’s Artemis II SLS (Space Launch System) rocket and Orion spacecraft slated to send four astronauts around the Moon began rolling to Launch Complex 39B at 12:20 a.m. EDT on Friday, March 20. Rollout operations at the agency’s Kennedy Space Center in Florida were delayed earlier in the day due to high winds in the area.

The trek to the pad is expected to take up to 12 hours, as NASA’s Crawler-Transporter 2 carefully carries the rocket on top of the Mobile Launcher approximately 4 miles along the crawlerway. A live feed of the rollout is available on NASA’s YouTube channel.

Following a successful wet dress rehearsal on February 21, teams identified an issue preventing helium from flowing to the rocket’s upper stage, prompting a return to the Vehicle Assembly Building (VAB) where the issue was repaired.

While the rocket and spacecraft were in the VAB, engineers also refreshed and retested several systems on the rocket. Engineers activated a new set of flight termination system batteries, replaced other batteries on the upper stage, core stage, and solid rocket boosters, and charged Orion’s launch abort system batteries. Engineers also replaced a seal on the core stage liquid oxygen feed line and reassembled and retested the oxygen tail service mast umbilical plate to confirm a tight seal interface.

Artemis II will send NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, along with CSA (Canadian Space Agency) astronaut Jeremy Hansen, on an approximately 10-day mission around the Moon and back, marking the first crewed flight of the Artemis program.

Canadarm2 Grips Cargo Spacecraft, Spacewalk Prep and Biology Continue (News Release)

A JAXA (Japan Aerospace Exploration Agency) cargo spacecraft is in the grasp of the Canadarm2 robotic arm following its detachment from the International Space Station’s Harmony module on Thursday. The Expedition 74 crew continued its spacewalk preparations, transferred more cargo, and conducted biology research throughout the day.

The HTV-X1 cargo spacecraft was uninstalled from Harmony with Canadarm2 at 2:26 p.m. EST on Thursday and maneuvered to an overnight parking position. During the crew’s sleep shift, Japanese mission controllers will conduct a laser-ranging sensor demonstration test with HTV-X1 still held by the robotic arm.

Then at 12 p.m. EST on Friday, robotics controllers will command the Canadarm2 to release HTV-X1 into Earth orbit. The spacecraft will remain at a safe distance from the station for approximately three months while conducting a series of remotely-controlled science experiments. NASA will broadcast the release live, beginning at 11:45 a.m. Friday on NASA+, Amazon Prime and the agency’s YouTube channel.

While robotic operations continued outside the space station, the astronauts pressed ahead with spacewalk preparations. NASA flight engineers Jessica Meir, Chris Williams and Jack Hathaway gathered together and reviewed the tools and equipment required to install a modification kit and route cables for a future roll-out solar array on the port side of the orbital outpost. NASA will soon announce the date and name the two spacewalkers who will exit the station’s Quest airlock into the vacuum of space for the roll-out solar array preparation work.

ESA (European Space Agency) astronaut Sophie Adenot began her shift packing cargo for disposal inside Northrop Grumman’s Cygnus XL cargo spacecraft attached to the Unity module’s Earth-facing port. Cygnus will conclude its mission soon at the orbital outpost that began on September 18 with its robotic capture and installation to Unity. Adenot also worked in the Kibo laboratory module removing computer and electronics hardware for stowage and later reuse.

Cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev teamed up early Thursday for a Roscosmos digestion study. Shortly after waking, the duo scanned their stomachs with an ultrasound device before eating their breakfast. After their meal, the station commander and flight engineer repeated the stomach scans helping researchers understand how the digestive system adapts to weightlessness.

Flight Engineer Andrey Fedyaev kicked off his shift servicing the Elektron oxygen generator and its components in the station’s Roscosmos segment. Fedyaev then inspected video recording gear, downloaded video and imagery for mission controllers, and installed automated Earth observation hardware to capture imagery of islands across the Asia-Pacific region.

NASA Repairs Upper Stage Helium Flow, Preps Continue Ahead of Rollout (News Release)

With NASA’s Artemis II SLS (Space Launch System) rocket and Orion spacecraft in the Vehicle Assembly Building at the agency’s Kennedy Space Center in Florida, technicians have accessed the launch vehicle stage adapter to inspect components that prevented helium from flowing to the upper stage after a February 21 wet dress rehearsal.

Engineers determined that a seal in the quick disconnect, through which helium flows from the ground systems to the rocket, was obstructing the pathway. The team removed the quick disconnect, reassembled the system, and began validating the repairs to the upper stage by running a reduced flow rate of helium through the mechanism to ensure that the issue was resolved. Engineers are assessing what allowed the seal to become dislodged to prevent the issue from recurring.

While the upper stage repair has been underway, technicians have also been working to refresh other systems on the rocket. They are activating a new set of flight termination system batteries ahead of end-to-end retesting of the system and are also replacing the flight batteries on the upper stage, core stage, and solid rocket boosters, and charging the Orion launch abort system batteries. Work to replace a seal on the core stage liquid oxygen line feed system began on March 2.

Once complete, teams will reassemble the oxygen tail service mast umbilical plate and perform various integrity tests to ensure that the seal interface is tight.

Work on the rocket and spacecraft will continue in the coming weeks as NASA prepares for rolling the rocket out to the launch pad again later this month ahead of a potential launch in April.

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 to Rollback Artemis II Rocket, Spacecraft (News Release)

Weather pending, NASA will roll the SLS (Space Launch System) rocket and Orion spacecraft for Artemis II off the launch pad at the agency’s Kennedy Space Center in Florida as soon as Tuesday, February 24.

Engineers are continuing to prepare for the move after encountering an issue with the flow of helium to the rocket’s upper stage.

On February 21, managers decided to remove recently-installed platforms before high winds descend on the Space Coast, which poised teams for rollback while discussions about the issue were ongoing. Returning to the Vehicle Assembly Building at Kennedy is required to determine the cause of the issue and fix it.

Teams are reviewing the exact time to begin the approximately 4 mile, multi-hour trek.

The quick work to begin preparations for rolling the rocket and spacecraft back to the VAB potentially preserves the April launch window, pending the outcome of data findings, repair efforts, and how the schedule comes to fruition in the coming days and weeks.

The Artemis II crew members were released from quarantine the evening of February 21 and remain in Houston.

NASA will hold a media event in the coming days to discuss rollback, and plans for the Artemis II test flight.
