D-RATS astronauts test lunar technology in the desert

A team comprising people from NASA and its Japanese counterpart, JAXA, is currently in an Arizona desert carrying out tests of a rover and other technology that could one day be heading to the moon.

NASA’s Desert Research and Technology Studies (D-RATS) has been operating on an annual basis since the late 1990s, but the work is becoming increasingly important as the space agency is on the verge of launching a new era of lunar exploration through its Artemis program.

Current D-RATS members include NASA astronauts Jessica Meir and Stan Love, along with their Japanese colleagues Aki Hoshide and Norishige Kanai.

“D-RATS will consist of three simulated missions, each lasting three days, and will be located at Black Point Lava Flow, 40 miles from Flagstaff, Arizona,” NASA explained in a post on its website. “This unique location will allow teams to emulate conditions astronauts will experience near the lunar South Pole during Artemis missions including challenging terrain, interesting geology, and minimal communications.

The astronauts’ “day in the life” desert missions will run through October 22 and include thorough testing of JAXA’s pressurized rover. The astronauts will live and work inside the vehicle for 72 hours at a time so that engineers can determine if it’s able to safely handle the demanding lunar conditions.

“Operated like a real mission, the Desert RATS crews will carefully rove the desert, exiting the vehicle in their mock spacesuits when they come across scientifically intriguing regions to explore,” NASA said. “At NASA’s Johnson Space Center in Houston, a Mission Control team will track crew movement and activities, help them stay on schedule, and troubleshoot for them if problems arise.”

The tests will help engineers to discover ways to design, build, and operate better equipment, as well as establish requirements for operations and procedures essential to any crewed lunar mission.

NASA’s Artemis program should get underway next month with the first launch of its next-generation Space Launch System rocket. The Artemis I mission has already suffered several delays due to technical issues, but when it finally gets underway it’ll send an uncrewed Orion spacecraft on a fly-by of the moon as part of a test flight.

If successful, Artemis II will send a crew on the same journey, while Artemis III, which could take place as early as 2025, will endeavor to put the first woman and first person of color on the lunar surface. Following that, NASA and its partners will set about building a permanent moon base, which could act as a stepping stone for the first crewed mission to Mars, possibly in the late 2030s.

NASA’s Artemis moon astronauts suit up for mission practice run
NASA's crew for the Artemis II lunar mission.

The four Artemis II astronauts who will embark on a flyby of the moon in November next year successfully conducted a pre-launch practice run on Wednesday.

In line with launch day procedures, NASA astronauts Christina Koch, Victor Glover, and Reid Wiseman, along with Canadian Space Agency astronaut Jeremy Hansen, started the day by waking up inside the crew quarters at the Neil Armstrong Operations and Checkout Building at the Kennedy Space Center in Florida.

NASA performs critical tests for Artemis V moon rocket
NASA tests the SLS rocket's new RS-25 engines for the Artemis V mission.

NASA is performing hot fire tests of the new RS-25 engines that will power the agency’s Space Launch System (SLS) rocket toward the moon in the Artemis V mission, currently scheduled for 2029.

“NASA entered the stretch run of a key RS-25 certification engine test series with a successful hot fire [on] June 1, continuing to set the stage for future Artemis missions to the moon,” the agency said in a post on its website.

Here are the 4 astronauts who will travel to the moon for Artemis II

NASA has announced the four crew members who will be traveling around the moon for the Artemis II mission, the first time that humans will have left low-Earth orbit in over 50 years.

The crew consists of three NASA astronauts and one Canadian Space Agency (CSA) astronaut, who will travel on a 10-day flight using the recently tested Space Launch System rocket and Orion spacecraft which flew uncrewed on the Artemis I mission late last year. They will test out new technologies and systems ahead of a planned Artemis III mission which will see humans land on the moon for the first time since 1972.
