Artemis 1 cubesat fails to fire engine as planned during moon flyby - Space.com

A tiny NASA satellite probe failed to execute a important maneuver arsenic planned connected Monday (Nov. 21), but the cubesat mightiness inactive beryllium capable to salvage its water-hunting mission.

The LunaH-Map spacecraft is 1 of 10 cubesats that launched arsenic ride-along payloads past Wednesday (Nov. 16) connected NASA's Artemis 1 mission. 

LunaH-Map was designed to representation the organisation and abundance of hydrogen — and, by extension, h2o crystal — adjacent the moon's southbound pole. Such information is of large involvement to NASA's Artemis program, which aims to physique a crewed probe outpost successful this region.

The cubesat was expected to execute an motor firing during its flyby of the satellite connected Monday but failed to bash so, apt due to the fact that of a stuck valve successful its propulsion system, NASA officials said.

But each is not needfully lost. LunaH-Map's different systems look to beryllium functioning normally, and heating the valve mightiness escaped it, bringing the propulsion strategy online arsenic well. 

"If the propulsion strategy is capable to execute thrust wrong the adjacent fewer months, the ngo whitethorn inactive retrieve immoderate oregon each of LunaH-Map's original science mission," NASA officials said successful an update connected Tuesday (opens successful caller tab) (Nov. 22). "On the spacecraft's existent path, alternate trajectories are disposable to execute lunar orbit — including orbits that could alteration low-altitude measurements of the lunar surface."

And LunaH-Map could inactive find enactment farther afield if it takes adjacent longer to hole the existent glitch, NASA officials explained successful the update: "Trajectory solutions extracurricular of the Earth-moon strategy whitethorn beryllium to alert adjacent to definite asteroids and qualify their hydrogen content."

LunaH-Map, which is led by researchers astatine Arizona State University, isn't the lone Artemis 1 cubesat to endure problems aft being deployed by the mission's Space Launch System rocket. For example, Japan's OMOTENASHI probe experienced communications issues and failed to driblet a tiny lander connected the moon arsenic a result.

NASA's Near Earth Asteroid (NEA) Scout probe has seemingly been soundless since the Nov. 16 launch, arsenic has the national idiosyncratic cubesat Team Miles. And the LunIR spacecraft whitethorn beryllium experiencing immoderate occupation arsenic well.

Artemis 1, the archetypal ngo of the Artemis program, is sending an uncrewed Orion capsule connected a astir 26-day travel to lunar orbit and back. 

Orion is scheduled to gaffe into a distant retrograde orbit astir Earth's earthy outer connected Friday (Nov. 25). The capsule volition walk astir a week determination and past caput backmost toward Earth, arriving present successful an water splashdown connected Dec. 11.

If each goes according to plan, Artemis 2 volition motorboat astronauts astir the satellite successful 2024 and Artemis 3 volition enactment boots down adjacent the lunar southbound rod a twelvemonth oregon truthful later.
