NASA Readies for Future Artemis Moon Missions with Rocket Engine Test Series (Press Release)

NASA marked a significant milestone Sept. 30 in its plans for future missions to the Moon and, eventually, Mars with completion of an RS-25 single-engine Retrofit-2 test series at Stennis Space Center near Bay St. Louis, Mississippi.

A full-duration hot fire of RS-25 developmental engine No. 0528 on the A-1 Test Stand at Stennis culminated a seven-test series to support development and production of new engines for the agency’s Space Launch System (SLS) rocket on future missions.

“This successful test series for the Space Launch System RS-25 engine puts us one step closer to manufacturing the first new set of engines for future Artemis missions to the Moon,” said Johnny Heflin, manager of the SLS liquid engines office at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “We are testing engine parts made with advanced manufacturing techniques that can reduce the cost of each engine by more than 30 percent yet still maintain the RS-25 engine’s reliability and high performance.”

During the Sept. 30 hot fire, operators fired RS-25 developmental engine No. 0528, used for each of the seven tests in the series, for more than eight minutes (500 seconds), the same time required during an actual launch.

The test series provided valuable information to Aerojet Rocketdyne, lead contractor for the SLS engines, as it produces engines for use after the Artemis IV mission to the Moon. Operators collected hot fire data to demonstrate and verify various engine capabilities, and to evaluate new engine components manufactured with cutting-edge and cost-saving technologies and reduce operational risk.

Tested components included a 3D-printed pogo accumulator to dampen pressure oscillations that can cause flight instability and a main combustion chamber fabricated using a hot isostatic pressure (HIP) bonding technique. These components are significant early milestones in NASA’s and Aerojet Rocketdyne’s effort to maximize state-of-the-art manufacturing methods to significantly reduce the cost and time needed to build new RS-25 engines.

The Sept. 30 test was delayed from its original date due to impacts from Hurricane Ida, which struck the Gulf Coast region on Aug. 29. The storm initially impacted propellant deliveries to the center, necessitating a delay as suppliers recovered full capabilities.

“I am proud to see how the test team and our propellant suppliers overcame the impacts of Hurricane Ida to get us back to testing the RS-25,” Stennis RS-25 Project Manager Chip Ellis said. “With each test we learn more and more about the RS-25 engine and how it operates. And it is exciting to know that what we are doing contributes to the safety of the astronauts that will fly on SLS.”

Four RS-25 engines, along with a pair of solid rocket boosters, will help power SLS at launch. Firing simultaneously, the engines will generate a combined 1.6 million pounds of thrust at liftoff and 2 million pounds during ascent.

Previous RS-25 testing at Stennis began Jan. 9, 2015, and concluded April 4, 2019. During this period, NASA completed acceptance testing of former space shuttle main engines that will help power the first four SLS missions, conducted developmental and flightworthiness testing for all 16 new controllers (plus one spare) to be used on the heritage RS-25 engines, and demonstrated the ability of RS-25 engines to perform at the higher power level required to launch the super-heavy SLS rocket.

The first hot fire of the most current series was conducted on Jan. 28, 2021. Over the course of the seven-part test series, which coincided with Green Run testing of the SLS core stage at Stennis, developmental engine No. 0528 underwent 3,650 seconds of hot fire. The schedule included six full-duration, hot fire tests of more than eight minutes (500 seconds) and one hot fire of just under 11 minutes (650 seconds). A full-duration test refers to the time the engine must fire during an actual launch in order to power SLS towards orbit. Longer duration hot fires are conducted to test the limits of engine performance.

The Retrofit-2 test series followed major maintenance and upgrade projects on the A-1 Test Stand, including installation of a new NASA-designed-and-manufactured thrust vector control system on the structure that allows operators to “gimbal” test RS-25 engines, moving them on a tight circular axis. Gimbaling is a critical capability that ensures SLS can maintain a proper flight trajectory.

Operators are scheduled to begin a follow-up Retrofit-3 test series, using RS-25 developmental engine No. 0525, on the A-1 Test Stand later this fall. The new series will continue to collect data for new engine production.

NASA is building SLS as the world’s most powerful rocket. With Artemis, NASA will land the first woman and the first person of color on the lunar surface and establish long-term exploration at the Moon in preparation for human missions to Mars. SLS and the Orion spacecraft, along with the commercial Human Landing System and the Gateway in orbit around the Moon, are NASA’s backbone for deep space exploration. The agency is working towards the launch of the Artemis I uncrewed flight test in upcoming months, which will pave the way for future missions.

RS-25 tests at Stennis are conducted by a combined team of NASA, Aerojet Rocketdyne and Syncom Space Services operators. Syncom Space Services is the prime contractor for Stennis facilities and operations.

Photos of the Day: Nauka Begins One of Its Roles as the Space Station's Newest Docking Port...

ESA / Thomas Pesquet

Several hours ago, European Space Agency astronaut Thomas Pesquet took these amazing photos showing the Soyuz MS-18 capsule relocating from its docking port on the International Space Station's (ISS) Rassvet module to Russia's brand-new Nauka science laboratory.

The Soyuz spacecraft—which carried cosmonauts Oleg Novitskiy and Pyotr Dubrov, as well as NASA astronaut Mark Vande Hei—docked to Nauka at 9:04 AM, Eastern Daylight Time (6:04 AM, Pacific Daylight Time) today.

The relocation clears the way for next month's arrival of the Soyuz MS-19 capsule...whose crew consists of cosmonaut Anton Shkaplerov, film director Klim Shipenko and actress Yulia Peresild, respectively.

Shipenko and Peresild will shoot scenes for a Russian movie [titled Vyzov (or The Challenge)] aboard the ISS after their Soyuz launches from Baikonur Cosmodrome in Kazakhstan on Tuesday, October 5, and then docks to the Rassvet module later that day.

NASA Begins a New Round of Competition to Select the Next Human Landing System...

NASA

NASA Selects Five U.S. Companies to Mature Artemis Lander Concepts (Press Release - September 14)

NASA has selected five U.S. companies to help the agency enable a steady pace of crewed trips to the lunar surface under the agency’s Artemis program. These companies will make advancements toward sustainable Human Landing System concepts, conduct risk-reduction activities, and provide feedback on NASA’s requirements to cultivate industry capabilities for crewed lunar landing missions.

The awards under the Next Space Technologies for Exploration Partnerships (NextSTEP-2) Appendix N broad agency announcement are firm fixed-price, milestone-based contracts. The total combined value for the awards is $146 million, and the work will be conducted over the next 15 months. The companies that received awards and their award values are:

- Blue Origin Federation of Kent, Washington, $25.6 million.
- Dynetics (a Leidos company) of Huntsville, Alabama, $40.8 million.
- Lockheed Martin of Littleton, Colorado, $35.2 million.
- Northrop Grumman of Dulles, Virginia, $34.8 million.
- SpaceX of Hawthorne, California, $9.4 million.

“Establishing a long-term human presence on the Moon through recurring services using lunar landers is a major Artemis goal,” said Kathy Lueders, NASA’s associate administrator for Human Exploration and Operations at Headquarters in Washington. “This critical step lays the foundation for U.S. leadership in learning more about the Moon and for learning how to live and work in deep space for future missions farther into the solar system.”

The selected companies will develop lander design concepts, evaluating their performance, design, construction standards, mission assurance requirements, interfaces, safety, crew health accommodations, and medical capabilities. The companies will also mitigate lunar lander risks by conducting critical component tests and advancing the maturity of key technologies.

The work from these companies will ultimately help shape the strategy and requirements for a future NASA solicitation to provide regular astronaut transportation from lunar orbit to the surface of the Moon.

"Collaboration with our partners is critical to achieving NASA’s long-term Artemis lunar exploration goals,” said Lisa Watson-Morgan, Human Landing System Program manager at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “By partnering with innovative U.S. companies, we will establish a robust lunar economy while exploring new areas of the Moon for generations to come.”

This opportunity is distinct from the initial crewed lunar landing demonstration mission awarded under the NextSTEP-2 Appendix H procurement, which will serve as the proof of concept for the Artemis architecture.

NASA’s goals under Artemis include enabling a safe and cost-efficient long-term approach to accessing the lunar surface and becoming one of multiple customers purchasing services in a lunar transportation market. Much of what the agency develops for the Moon will be applied to future exploration at Mars.

NASA’s Artemis missions include landing the first woman and first person of color on the lunar surface, sending a suite of new science instruments and technology demonstrations to study the Moon, and establishing a long-term presence there.

Artemis 1 Update: The Space Launch System Has One More Test to Go Before Orion Is Attached to It...

NASA

SLS Modal Testing: Finding the Range of a Rocket’s Reflexes (News Release)

Before NASA’s Space Launch System (SLS) launches the Artemis I mission to the Moon, teams inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida will conduct a series of tests to determine the deep space rocket’s reflexes. During launch and flight, SLS will experience and react to a series of frequencies and vibrations.

Engineers conduct integrated modal testing to determine the full range of these frequencies and vibrations so that the flight software and navigation systems can safely guide the rocket through launch and ascent. To do that, technicians use a test version of the Orion stage adapter and Orion mass simulator to determine the natural frequencies, flexes, and vibration patterns of the SLS rocket.

Artemis I stacking will resume with flight versions of the Orion stage adapter and NASA’s Orion spacecraft following completion of the test series.

With Artemis, NASA will land the first woman and the first person of color on the lunar surface and establish long-term exploration at the Moon in preparation for human missions to Mars.

SLS and NASA’s Orion spacecraft, along with the commercial Human Landing System and the Gateway in orbit around the Moon, are NASA’s backbone for deep space exploration. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission.

Photos of the Day: An Unobstructed View of Artemis 1's SLS Rocket Inside the Vehicle Assembly Building...

NASA / Frank Michaux

Happy First Day of Autumn! Just thought I'd share these four photos showing the Space Launch System (SLS) rocket after work platforms were retracted inside the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida...on Friday, September 17.

The removal of these platforms from around SLS paved the way for the Umbilical Release and Retract Test—which was originally supposed to occur about a month ago, but instead conducted last Sunday, September 19.

As of this update, the Integrated Modal Test should've begun on SLS and its mobile launcher inside the VAB. Once completed, this clears the way for the Mass Simulator for Orion and the Orion stage adapter's (OSA) structural test article to be removed from the mammoth Moon rocket.

By early next month, the flight-worthy OSA and the actual Orion spacecraft should be mated to SLS, completing assembly of the giant launch vehicle as it continues to be prepped for Artemis 1. Stay tuned!

A New Era of Human Spaceflight Has Finally Begun!

John Kraus Photography

Inspiration4 Crew Launches First All-Civilian Orbital Mission to Space (Press Release)

CAPE CANAVERAL, FL – On September 15 the crew of Inspiration4, the world’s first all-civilian human spaceflight mission to orbit, officially ushered in a new era of space exploration at 8:02:56 PM EDT as SpaceX’s Falcon 9 lifted off from historic Launch Complex 39A at NASA’s Kennedy Space Center.

“Our crew carries the responsibility and importance of this mission as we prepare to blast off,” said Inspiration4 Commander Jared Isaacman just before launch. “We have been well-prepared for the challenges ahead of us the next three days and look forward to sharing our experience with the world as we continue to bring attention to St. Jude Children’s Research Hospital® here on earth.”

Since the mission’s announcement in March 2021, the Inspiration4 crew has spent the past six months completing a wide range of training activities including centrifuge training, Dragon simulations, observations of other launch operations, Zero-G plane training, altitude training and additional classroom, simulation and medical testing. This intensive, focused preparation was essential to helping four diverse strangers grow into their new roles as the first all-civilian astronaut crew to orbit Earth.

The crew’s collective goal has not only been to fly to space but also make a significant contribution in the fight to cure childhood cancer back on Earth. Started by an initial $100 million gift from Isaacman to St. Jude, Inspiration4 has a fundraising goal to raise $200 million through February 2022 to help accelerate research advancements and save more children worldwide. To date, the mission has a commitment of more than $130 million with new auction items and ways to support being shared during and after the mission. To get involved, click here.

“We are thankful to Jared for his incredible leadership as the commander of the historic mission and for his work helping to raise $200 million for St. Jude Children’s Research Hospital,” said Richard C. Shadyac Jr., President and CEO of ALSAC, the fundraising and awareness organization for St. Jude Children’s Research Hospital. “The significance of Inspiration4 cannot be overstated. The mission ushers in a new era in citizen space travel and gives hope to children. Cancer is diagnosed each year in about 400,000 children worldwide. Curing catastrophic diseases in children is a multi-trillion-dollar, multi-year problem and the public’s support – through initiatives like Inspiration4 – makes it possible for us to raise the critical funds needed to help save children everywhere.”

The Inspiration4 mission marks several historic milestones for human space exploration. They will be the first all-civilian crew to orbit Earth, the first free-flight Crew Dragon mission, and the first orbital human spaceflight mission that will not dock with a space station since the final Hubble mission on STS-125 in 2009. Inspiration4 is being monitored at every step by SpaceX mission control as the spacecraft orbits the planet every 90 minutes along a custom flight path. The crew is targeting an approximate 575 km orbit, flying farther than any human since Hubble, for an expected mission duration of approximately three days. To learn about the research and activities the crew will participate in during the mission, see the previous announcement here.

“The all-civilian Inspiration4 astronauts are paving the way for a future where space is more accessible to all who wish to go, and we are so proud that they entrusted us to fly them,” said SpaceX President and Chief Operating Officer Gwynne Shotwell. “On behalf of all SpaceX employees, I want to thank the crew and their families for allowing us to be a part of their historic mission.”

After an approximately three-day journey, the Inspiration4 team will re-enter the Earth’s atmosphere for a soft water landing off the coast of Florida.

The mission can be tracked at spacex.com/launches through their Dragon Tracker tool. To see updates on Inspiration4’s journey throughout the mission, visit www.inspiration4.com and follow Twitter (@inspiration4x), Facebook (@inspiration4mission), Instagram (@inspiration4) and YouTube (@Inspiration4).
