(23 September 2020 – NASA) NASA engineers are laying the foundation for the moonwalks the first woman and next man will conduct when they land on the lunar South Pole in 2024 as part of the Artemis program.

At the agency’s Johnson Space Center in Houston, teams are testing the tools and developing training approaches for lunar surface operations.

As part of a test series occurring in the Neutral Buoyancy Lab (NBL) at Johnson, astronauts in a demonstration version of the exploration spacesuit and engineers in “hard hat” dive equipment are simulating several different tasks crew could do on the surface of the Moon.

“This early testing will help determine the best complement of facilities for hardware development and requirements for future Artemis training and missions,” said Daren Welsh, extravehicular activity test lead for these Artemis preparation test runs. “At the same time, we are going to be able to gather valuable feedback on spacewalk tools and procedures that will help inform some of the objectives for the missions.”

The tests are focused on evaluating Johnson’s facilities for Artemis spacewalk testing, development, and crew training. Astronauts are practicing a variety of tasks, including picking up samples of lunar regolith, examining a lunar lander, and planting an American flag. There are many fundamentals that the teams have to consider and work through, such as how crew might get up and down a ladder safely, how to swing a chisel safely, and how to conduct successful moonwalks in different lighting conditions than the Apollo-era moonwalks. The tests will inform future mission planning, including how many spacewalks to conduct during a mission, how long they’ll be, and how far away from a lander the crew will travel.

While NASA has extensive experience preparing astronauts for spacewalks in microgravity like those to construct and maintain the International Space Station over the past 20 years, preparing for Moon missions comes with different challenges.

“We can evaluate tools in a lab or the rock yard, but you can learn so much when you put a pressurized spacesuit on and have to work within the limitations of its mobility,” Welsh said. “These NBL runs are so valuable for understanding the human performance component and ensuring our astronauts are as safe as possible.”

In addition to testing in the NBL, teams also are using different analog environments to simulate lunar conditions. Tests are occurring at Johnson’s rock yard, a large, outdoor test area which simulates general features of the lunar surface terrain.

Rock yard testing is a critical analog environment for spacewalk tool development and operations. The interaction between the crewmembers and the Earth-based teams in mission control and the science control centers allows engineers to mature concepts of mission operations. The testing reveals spacewalking tool design improvements and helps formulate operational timelines. Analog environments allow iterations on designs to occur quickly such that the revisions can be reevaluated in subsequent tests.

“We have experience with space station, but we need to determine how we’re going to train the crew for surface operations during these specific missions,” Welsh said. “There is a lot of work to do to get the facilities ready to work for lunar missions and figure out how to facilitate the training.”

This collaborative effort is already paying dividends for the team as they are becoming more familiar with the surface operation concepts. As the tests continue, the team is expanding the scope of the testing, with plans to complete full lunar spacewalk timelines.

With the Artemis program, NASA will land the first woman and next man on the Moon in 2024, using innovative technologies to explore more of the lunar surface than ever before. We will collaborate with our commercial and international partners and establish sustainable exploration by the end of the decade. Then, we will use what we learn on and around the Moon to take the next giant leap – sending astronauts to Mars.

Masten Space Systems awarded two NASA Tipping Point contracts

Masten Space Systems awarded two NASA Tipping Point contracts

(21 October 2020 – Masten Space Systems) NASA and Masten Space Systems announced that the Space Technology Mission Directorate has chosen Masten for two Tipping Point awards as part of the agency’s Artemis mission to return to the Moon.

The first award is for Masten’s Metal Oxidation Warming System (MOWS) which is being developed in partnership with Penn State as a chemical heating solution to help spacecraft survive in sunlight-deprived lunar environments. The second award will drive completion of Masten’s state-of-the-art aerospace testbed, named Xogdor, to provide the industry an updated flight test analog for critical Artemis technologies.

“We are excited to see such an auspicious group of Tipping Point awards this year,” said Masten CEO Sean Mahoney. “It’s an honor to be in such great company with all these amazing awards as NASA’s forward-looking Space Technology Mission Directorate steps up to fund the private companies who are producing out-of-the-box innovations that will take America back to the Moon, to stay.”

In partnership with Penn State, Masten will mature MOWS, a lunar warming solution with electricity cogeneration that allows spacecraft systems to survive the lunar night and operate in shadowed lunar regions. MOWS employs moderate-temperature chemical reactions for thermal control with order-of-magnitude greater specific energy than battery-based approaches. MOWS is useful for both robotic and manned missions, as both require thermal control for extended surface operations.

“MOWS technology benefits both NASA and commercial missions as it significantly expands the scope of lunar exploration missions,” said Matthew Kuhns, chief engineer at Masten. “The ability to survive the lunar night extends mission durations beyond the current capability of around 14 days, allowing missions at least six weeks, two lunar days and one lunar night, and possibly longer, greatly increasing our capacity to perform more science, operate customer payloads, and reduce risk for future Artemis missions on the Moon.”

Masten will mature its Xogdor flight vehicle to operational service to provide an updated system for testing aerospace technologies in a relevant flight environment. Over this three year project, Masten will complete the development and flight testing of a Xogdor vehicle. The defined effort will support risk reduction of technologies through flight testing in pursuit of NASA’s Moon-to-Mars campaign with a focus on building an EDL (Entry, Descent, Landing) test capability for near-term lunar missions. Xogdor will be the sixth vehicle in Masten’s line of reusable rockets, which have had more than 600 successful VTVL (Vertical Takeoff Vertical Landing) flights over 15 years of heritage.

“Xogdor is poised to become the industry’s state-of-the-art testing analog with performance capabilities far exceeding those of currently available EDL testbeds,” said Masten CTO, Dave Masten. “Through this Masten-NASA partnership, Xogdor will be available to test critical Artemis technologies, including hazard detection instruments, precision landing avionics, innovative flight software, Plume Surface Interaction (PSI) experiments, and other critical EDL experiments as early as 2023.”

“P3 is proud to be supporting Masten with Champ Turbopumps for the Xogdor rocket for this important NASA Tipping Point program,” said Phil Pelfrey, president of P3 Technologies.

“This is the most Tipping Point proposals NASA has selected at once and by far the largest collective award value,” said NASA’s Associate Administrator for Space Technology Jim Reuter. “We are excited to see our investments and collaborative partnerships bring about new technologies for the Moon and beyond while also benefiting the commercial sector.”

About NASA STMD’s Tipping Point Program

Through the “Tipping Point” solicitation, NASA seeks industry-developed space technologies that can foster the development of commercial space capabilities and benefit future NASA missions. A technology is considered at a tipping point if an investment in a demonstration will significantly mature the technology, increase the likelihood of infusion into a commercial space application, and bring the technology to market for both government and commercial applications. The public-private partnerships established through Tipping Point selections combine NASA resources with an industry contribution of at least 25% of the program costs, shepherding the development of critical space technologies while also saving the agency, and American taxpayers, money.
