nonrational Machines’spacecraft touched down yesterday on the lunar surface . . . sideways . chief executive officer Steve Altemus support during a press group discussion Friday that , while it was n’t a consummate landing place , it ’s nothing unforesightful of a miracle the ballistic capsule landed intact at all .
Using a small model of the lander , Altemus demonstrated how applied scientist consider the spacecraft , shout out Odysseus , made its lineage commit the most late telemetry data .
“ The fomite is stable nigh or at our intended landing site , ” Altemus said . “ We ’re downloading data point from the buffer store in the spacecraft and command the spacecraft . ”
Intuitive Machines affirm yesterday that the lander rival down on the surface at 5:24 p.m. Central Time — making the company the first to put a privately build space vehicle on the lunation — but many particular about the vehicle ’s health were unknown . Part of the reason for that is because the onboard camera , an cat’s-paw called EagleCam , was powered down during landing place . Without images , locomotive engineer had to swear on other data to determine the lander ’s orientation after it land .
nonrational Machines makes history by landing the first commercial-grade spacecraft on the moon
Even now , the company is continuing to rebuild the series of event that lead up to the historic landing . The company originally think Odysseuswas actually erect , but Altemus enunciate that was based on “ stale ” telemetry datum . presently uncommitted information is point that the ballistic capsule was indeed upright at touchdown , but because it was also moving horizontally — and a lilliputian too promptly — it ’s likely that one of its legs caught on something or broke , causing it to tilt over .

The serious news is that most of the onboard payloads are not on the downward - facing panel — the only one that does not need to operate on the lunar surface . The party was able to reassert that many of the major subsystems — let in the solar arrays provide baron to the spacecraft and the onboard payloads — are performing well .
Much of the mission ’s achiever come down to very quick thinking by Intuitive Machines ’ mission controllers — and just a solidus of very good luck .
The navigational issues take up after Odysseus conducted a plan maneuver called lunar orbital insertion on Wednesday Nox , which put it in an oval-shaped sphere around the moon . That stop up being highly “ fortuitous , ” Altemus say , because it led mission restrainer to try out to use a navigational subsystem call “ optical maser rangefinders ” far sooner than contrive ( the lasers were going to be activated for the first clock time during the terminal descent phase ) .
After review the data point , the fellowship realized the break of day of landing that the optical maser were not working — because they did not wrick off a physical safe substitution on the component while it was still on the ground .
These lasers specify vital variable for landing , like altitude and horizontal velocity ; with them non - functional , Odysseus could ’ve give in to the fate of so many other landers and crashed on the aerofoil . The company considered a handful of options , but ultimately they decided to employ a NASA Christian Johann Doppler lidar payload that was think as a engineering science demo . They directed Odysseus to orbit the moon for an extra two - hr period , to give them more time to stretch software package patches and reset the lander ’s guidance , seafaring and control system .
It was a remarkable last - minute save . Prasun Desai , deputy associate administrator of NASA ’s distance technology foreign mission directorate , say during the press conference that the agency was hop to get the Christian Johann Doppler lidar technology to a engineering readiness level ( TRL ) of 6 , but that the successful implementation onboard Odysseus has brought it to TRL 9 , the eminent level of readiness .
“ All that laborious work follow to carry yesterday when there was a technical topic and the squad make up one’s mind that hey , it was good to attempt to do the switch and rely on this tech monstrance , ” he said . “ Everything we translate from the telemetry received , which is confine to this point , until we get all the data back , is that the technology execute cleanly . ”
