TITUSVILLE, Fla. — SpaceX postponed the launch of an Intuitive Machines lunar lander by a day after encountering an issue fueling the spacecraft on the launch pad.
SpaceX introduced about 90 minutes earlier than the scheduled 12:57 a.m. Jap Feb. 14 launch of the IM-1 mission that it was delaying the launch by a day. The launch has been rescheduled for 1:05 a.m. Jap Feb. 15.
“Standing down from tonight’s try because of off-nominal methane temperatures previous to entering into methane load,” the corporate mentioned in its announcement of the delay, however offered no further particulars.
A novel side of the mission is that the Nova-C lander is loaded with liquid oxygen and methane propellants whereas on the launch pad. That fueling is meant to begin a couple of hours earlier than launch. SpaceX modified each the launch pad and the rocket to allow the lander to be fueled whereas contained in the payload fairing on the pad.
That requires extra coordination between the payload and the launch car in the course of the countdown than for a typical launch, mentioned Invoice Gerstenmaier, vp of construct and flight reliability at SpaceX, throughout a Feb. 13 briefing. “It’s just a little extra intense for us and just a little bit longer timeline than we sometimes have,” he mentioned.
SpaceX and Intuitive Machines carried out two moist costume rehearsals of the fueling course of final week. Trent Martin, vp of area methods at Intuitive Machines, mentioned in a Feb. 12 interview that the corporate tweaked a few of the parameters of the fueling course of after every take a look at however that each had gone nicely. “On each days we did the moist costume, we might have been go for launch,” he mentioned.
Lunar landers have historically used storable propellants and are fueled nicely upfront of being put in on the rocket. Using cryogenic propellants by the Nova-C lander requires it to be fueled as near launch as doable to restrict lack of propellants from boiling off.
“It permits us the chance to have a really massive rocket engine,” Martin mentioned on the Feb. 13 briefing. That enables a fast transit to the moon, with a touchdown scheduled for a few week after liftoff. “It permits us to function in a short time.”
He mentioned utilizing these propellants opens the door for future capabilities, together with the potential for getting liquid oxygen from lunar assets. That creates “the potential for a reusable rocket utilizing in-situ assets.”
The modifications by SpaceX to help IM-1 might be utilized by future Intuitive Machines landers, however Gerstenmaier mentioned they may be utilized by different clients. “We see this as a manner of basically advancing what sort of providers that we are able to present to future customers.”
Regardless of the delay, the touchdown, close to the Malapert A crater within the south polar areas of the moon, stays scheduled for Feb. 22. One ultimate launch alternative is on the market Feb. 16, after which Intuitive Machines must wait till March to strive once more.
The lander is carry six NASA payloads via the Industrial Lunar Payload Companies (CLPS) program below an award valued at about $118 million. Additionally it is carrying six non-NASA payloads from clients starting from artist Jeff Koons to Embry-Riddle Aeronautical College.
