A shoebox - sized orbiter may soon meet its untimely death after give way to go off its thrusters . The cubesat may have been compromised as it excessively waited for launch on board NASA ’s Space Launch System ( SLS ) rocket in betterment of the Artemis 1 mission last twelvemonth .
Engineers have been working to test andsalvage the LunaH - Map cubesat mission , hoping to engage its propulsion organization and give it a 2nd prospect at enter lunar electron orbit . It may be too late for the lilliputian satellite , however , as the squad behind the mission could cease its operations at the end of this month .
address at the Interplanetary Small Satellite Conference on Monday , Craig Hardgrove , the mission ’s principal investigator at Arizona State University , revealed that the team would officially call off the mission by the conclusion of May if they can not ignite the cubesat ’s propulsion organization , SpaceNews report .

The team is strain to free a stuck valve inside the system , which may be what ’s forestall the cubesat ’s pusher from firing . “ At some item , we may collapse through the valve , which could be good or could be very unfit , ” Hardgrove say . “ It ’s really all we have left to try at this point . ”
LunaH - Map , scant for Lunar Polar Hydrogen Mapper , is designed to revolve the Moon and explore possible pee - ice reservoirs beneath its surface . NASA launched the artificial satellite on November 16 , 2022 , along with nine other cubesats , as secondary payloadsaboard the Artemis 1 mission . Luna - H Map wasone of six Artemis cubesats equal to of transmitting confirmation signalsto primer teams , while the other four remained silent and were never hear from again .
Hardgrove charge the multiple delays of the Artemis 1 mission for the cubesat ’s unfortunate fate . The cubesats were tuck inside NASA ’s Space Launch System rocket in mid-2021 , and the commission teams had no room to access their consignment until launching . “ We had informed NASA that this propulsion system was not work up to withstand a long launching delay , longer than four or five months , ” Hardgrove said , according to SpaceNews . “ If we did n’t have to await over a class , I imagine we would at least have had a chance at comport our full scientific discipline mission . ”
Luna - H Map ’s thrusters use tincture of iodine as propellant , which Hardgrove suspects may have vaporized during the cubesat ’s long wait inside the rocket . As a result , the orbiter failed to discharge its thruster , preventing it from do its intended lunar flyby on November 21 , 2022 . Data collected by the mission engineers intimate that a valve within the spacecraft ’s thrusters is partially stuck , and they are attempting to use heaters in the propulsion system to free the valve .
The team still has a twain of weeks to try and free the plaguey valve in hopes that the diminutive satellite can perform some science in orbit .
