Astrobotic ’s lunar lander will be reentering Earth ’s atmosphere over a removed part of the South Pacific Ocean tomorrow afternoon , bringing to a shut the failed moonlight landing charge .
The Peregrine lunar lander is expected to reenter around 4PM EST over an unpeopled stretchiness of ocean near Fiji , according to coordinates Astrobotic posted in a Wednesday update . The spacecraft will not survive reentry . The company said it had been working with NASA to monitor its re - entry path and ensure Peregrine ’s reentry is both dependable and predicable .
Pittsburgh - based Astrobotic has been providing frequent updates on the Peregrine lunar lander since it launched on United Launch Alliance ’s Vulcan Centaur on January 8 . While the launch was execute with no issues , Astrobotic report an unusual person with the spacecraft mere hour after it was deploy in orbit .
The informant of the anomaly was an on-going propellent leak , which were preventing Peregrine from pointing its solar arrays at the sun . While Astrobotic engineers were successful in reorienting the arrays , the company later suppose that it distrust the root lawsuit of the issue was a decisive propellent leak in the propulsion arrangement . That likely came down to a valve in the pressurant system that fail to close .
The company confirmed that there was“no prospect of a soft landing place on the moon”due to the leak the following day .
Astrobotic has extended the lifespan of the mission far longer than it in the first place thought possible : the same Clarence Day that the company confirmed a synodic month landing place was off the tabular array , it judge that the spacecraft had only 40 hours of propellant left . But by the time it reenters the atmosphere tomorrow , Peregrine will have manoeuvre in space for over ten days .
Due to the propellant leak , Astrobotic say it had devised a two - whole tone process to maneuver the ballistic capsule to the projected trajectory for reentry . In the first , the ship’s company fired the five main engines in very short pulsing , because a longer burning was taken off the table due to the escape . Peregrine executed 23 little principal locomotive engine burns overall .

The society also adjusted the spacecraft ’s “ attitude , ” or orientation , so that the leaking propellent shift Peregrine toward the South Pacific Ocean .
“ The procedures the team executed were to downplay the risk of rubble reaching land , ” Astrobotic said in a Wednesday statement . “ Astrobotic continues to work closely with NASA and other relevant politics office to keep everyone informed and to solicit feedback as appropriate . ”
Despite the troupe not achieving the mission objective , Astrobotic sound out it was able-bodied to welcome worthful data from many of the payloads on table . A percentage of those warhead were scientific musical instrument and other research from NASA , which plunk for the mission in a $ 79.5 million contract awarded to Astrobotic in 2019 .
