A tiny NASA moon probe did not carry out a vital maneuver as deliberate on Monday (Nov. 21), however the cubesat would possibly nonetheless have the ability to salvage its water-hunting mission.
The LunaH-Map spacecraft is certainly one of 10 cubesats that launched as ride-along payloads last 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 knowledge is of nice curiosity to NASA’s Artemis program, which goals to construct a crewed analysis outpost on this area.

Dwell updates: NASA’s Artemis 1 moon mission
The cubesat was alleged to carry out an engine firing throughout its flyby of the moon on Monday however failed to take action, possible due to a caught valve in its propulsion system, NASA officers stated.
However all isn’t essentially misplaced. LunaH-Map’s different techniques 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 throughout the subsequent few months, the mission should get well some or all of LunaH-Map’s unique science mission,” NASA officers stated in an update 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 might nonetheless discover work farther afield if it takes even longer to repair the present glitch, NASA officers defined within the replace: “Trajectory options exterior of the Earth-moon system could 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 endure issues after being deployed by the mission’s Space Launch System rocket. For instance, Japan’s OMOTENASHI probe skilled communications points and failed to drop a tiny lander on the moon in consequence.
NASA’s Near Earth Asteroid (NEA) Scout probe has apparently been silent because the Nov. 16 launch, as has the citizen scientist cubesat Team 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 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 based on 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 yr or so later.
