CAPE CANAVERAL, Fla. — NASA loaded gasoline into its moon rocket Wednesday in a leak test ahead of a launch try as early as next week.
The daylong demo will decide whether or not the 322-foot (98-meter) rocket is prepared for its first test flight, a lunar-orbiting mission with mannequins as a substitute of astronauts.
Managers wish to confirm repairs to all of the hydrogen leaks that spoiled the primary two launch makes an attempt, in addition to earlier countdown assessments. So a lot hydrogen escaped throughout the countdown earlier this month that it exceeded NASA’s restrict by greater than double.
NASA changed two seals after the most recent delay. One had a tiny indentation.

“The team is really excited to get through this test. Everybody’s been working hard these last few weeks,” NASA engineer Wes Mosedale mentioned from Kennedy Space Center’s Launch Control.
Wednesday’s goal: pumping almost 1 million gallons (4 million liters) into the rocket, with minimal — or no — leakage. That would put NASA on the right track for a potential launch try Tuesday, offered the U.S. Space Force extends the certification of batteries on board which can be half of the flight security system.
Besides changing seals, NASA altered the fueling course of, easing extra slowly into the loading of the super-cold liquid hydrogen and oxygen. That means, the plumbing must be subjected to much less stress and be much less prone to spring a leak, in response to officers.
Once launched, the crew capsule atop the rocket would be the first to orbit the moon in 50 years. The $4.1 billion mission ought to final greater than 5 weeks, ending with a splashdown in the Pacific. Astronauts would climb aboard for the second test flight, dashing across the moon in 2024. The third mission, focused for 2025, would see a pair of astronauts really touchdown on the moon.
NASA’s Space Launch System rocket is extra highly effective than the Saturn V rocket that despatched Apollo astronauts to the moon throughout the late Nineteen Sixties and early Seventies. The engines and boosters are carryovers from the now-retired area shuttles. Just like now, NASA struggled with elusive hydrogen leaks throughout the shuttle period, particularly throughout the early Nineties.
