#WASHINGTON — The IM-1 mission by Intuitive Machines is on track to attempt a landing on the moon later this week after performing an in-flight test of its main engine.
The company announced late Feb. 16 that it fired the main engine of its Nova-C lander in a commissioning maneuver. The test was the first firing of the engine, which uses liquid oxygen and methane propellants, since its launch early Feb. 15 on a Falcon 9 from the Kennedy Space Center.
That test was originally scheduled for about 18 hours after liftoff. The company said earlier Feb. 16 it postponed the maneuver after finding it took longer than expected to chill the liquid oxygen feed line. The company also blamed intermittent communications with the lander for the delay.
