Astrobotic tender leave to its Peregrine lunar lander on Thursday as the spacecraft plunge through Earth ’s atmosphere , thereby prevent the give out mission from colliding into other space vehicle .
The Pittsburgh - based companylost contactwith Peregrine at around 3:50 p.m. ET , with the spacecraft potentially performing a ascendance reentry over the South Pacific at 4:04 p.m. ET . Astrobotic is still waiting on verification from government agencies that its lunar lander completely burnt up upon reentry , and that no pieces of the spacecraft crashed on Earth .
Peregrinelaunched on January 8on board United Launch Alliance ’s Vulcan Centaur rocket engine , with program to put down on the Moon in late February . However , the spacecraft receive a actuation anomaly early on that destruct Astrobotic ’s hope of becoming the first secret society to set ashore on the surface of the Moon .

“ I ’ll always recall the moment at Mission Control at ULA , when we were come from the highest highschool of a double-dyed launch , and came down to a lowest depression when we base out that the spacecraft no longer had … the propulsion needed to attempt a Moon landing place , ” CEO of Astrobotic John Thornton pronounce during a press conference held on Friday . “ That was certainly a tough moment for all of us . ”
Despite its propellant leak , Peregrine hang on through the depths of quad for more than 10 days , and its on board warhead even managed to power on . The lunar lander was stable and operational , but there was zero chance of it being able to get out off a soft landing on the Moon . With that in creative thinker , Astrobotic was present with the difficult decisiveness on what to do with the spacecraft .
On January 13 , the society had to decide whether to use Peregrine ’s propulsion system of rules to void Earth and go back out to the Moon or hold steady and have the ballistic capsule defend its flight and intersect with Earth .
“ We were assessing all of our options , and trying to project out what the next right-hand route for the spacecraft would be , ” Thornton said . “ We made the difficult decision to do nothing and to not take the hazard of firing those engines and to let the spacecraft fall back toward Earth . ”
The team behind the foreign mission was relate that , if the spacecraft were to go back out to the Moon , it could do a “ catastrophic situation ” by collide with another target , according to Thornton .
Astrobotic ’s lander is part of NASA ’s Commercial Lunar Payload Services ( CLPS ) opening , which is meant to help the outer space means in its pursuance to return humans to the Moon and make it a sustainable place for long - term human comportment . It was also entail to usher in a new epoch for private companies by granting them greater access to the lunar surface .
The 2,829 - British pound ( 1,283 - kilogram ) spacecraft was carrying24 dissimilar payloadsfrom three national space agencies , with 11 payloads from NASA alone , as well as a host of other payloads from private companies . Two of NASA ’s cargo , NSS ( Neutron Spectrometer System ) , LETS ( Linear Energy Transfer Spectrometer ) , made measurements of the radiation environment in the space between Earth and the Moon .
“ All the NASA scientific discipline payloads that could run by being power on did receive power and effectively tuck data during the time Peregrine was in flight , ” Joel Kearns , surrogate associate administrator for Exploration , Science Mission Directorate at NASA , said during the pressing group discussion . “ The NASA payload teams adjusted their operation and were able-bodied to demonstrate that they could have operated if those instruments had reached the Moon . ”
Astrobotic is preparing for its 2d attempt at a lunar touchdown with its Griffin mission , scheduled for launch by the end of the year . “ I ’m very much looking forward to that and I can just say that I am more confident than ever now that our next mission will be successful and solid ground on the surface of the Moon , ” Thornton said .
