A tiny NASA moon probe did not carry out a vital maneuver as deliberate on Monday (Nov. 21), however the cubesat would possibly nonetheless be capable to salvage its water-hunting mission.
The LunaH-Map spacecraft is considered one of 10 cubesats that launched as ride-along payloads final Wednesday (Nov. 16) on NASA’s Artemis 1 mission.
LunaH-Map was designed to map the distribution and abundance of hydrogen — and, by extension, water ice — close to the moon’s south pole. Such information is of nice curiosity to NASA’s Artemis program, which goals to construct a crewed analysis outpost on this area.

The cubesat was purported to carry out an engine firing throughout its flyby of the moon on Monday however failed to take action, seemingly due to a caught valve in its propulsion system, NASA officers mentioned.
However all shouldn’t be essentially misplaced. LunaH-Map’s different methods look like functioning usually, and heating the valve would possibly free it, bringing the propulsion system on-line as effectively.
“If the propulsion system is ready to obtain thrust inside the subsequent few months, the mission should still recuperate some or all of LunaH-Map’s authentic science mission,” NASA officers mentioned in an replace on Tuesday (opens in new tab) (Nov. 22). “On the spacecraft’s present path, alternate trajectories can be found to attain lunar orbit — together with orbits that might allow low-altitude measurements of the lunar floor.”
And LunaH-Map may nonetheless discover work farther afield if it takes even longer to repair the present glitch, NASA officers defined within the replace: “Trajectory options outdoors of the Earth-moon system might exist to fly near sure asteroids and characterize their hydrogen content material.”
LunaH-Map, which is led by researchers at Arizona State College, is not the one Artemis 1 cubesat to undergo issues after being deployed by the mission’s House Launch System rocket. For instance, Japan’s OMOTENASHI probe skilled communications points and did not drop a tiny lander on the moon in consequence.
NASA’s Close to Earth Asteroid (NEA) Scout probe has apparently been silent because the Nov. 16 launch, as has the citizen scientist cubesat Staff Miles. And the LunIR spacecraft could also be experiencing some bother as effectively.
Artemis 1, the primary mission of the Artemis program, is sending an uncrewed Orion capsule on an almost 26-day journey to lunar orbit and again.
Orion is scheduled to slide right into a distant retrograde orbit round Earth’s pure satellite tv for pc on Friday (Nov. 25). The capsule will spend a couple of week there after which head again towards Earth, arriving right here in an ocean splashdown on Dec. 11.
If all goes in response to plan, Artemis 2 will launch astronauts across the moon in 2024 and Artemis 3 will put boots down close to the lunar south pole a 12 months or so later.
