CAPE CANAVERAL, Fla. — NASA engineers are scrambling to stem a gas leak on its large new moon rocket forward of a essential take a look at flight Saturday, September 3.
NASA started fueling the Artemis 1 lunar rocket, NASA’s first Area Launch System (SLS), early Saturday to launch an uncrewed Orion spacecraft to the moon from Pad 39B right here at Kennedy Area Middle at 2 p.m. 5:00 p.m. EDT (6:17 p.m. GMT). However a persistent leak of liquid hydrogen detected slowed launch preparations.
NASA has a two-hour window to launch the mission, with promising climate forecasts ranging between 60% and 80% “go”, the company stated. You may watch its launch reside on-line.

The hydrogen leak was first detected at 7:15 a.m. EDT (11:15 GMT) as NASA started filling the huge SLS rocket with the 730,000 gallons of liquid hydrogen and liquid oxygen propellant required for launch. The leak is situated on the connection level of an 8-inch hydrogen line close to the engine compartment on the base of the 32-story rocket.
Engineers first tried warming the connector and cooling it with chilly gas to stem the leak, then tried repressurizing it with helium to repair it. Each makes an attempt failed, with NASA making an attempt this primary warming and cooling methodology once more to cease the leak.
A trouble-free refueling course of for Artemis 1 can take as much as 4 hours, however there’s not a lot room within the schedule for delays, NASA stated.
It was throughout the refueling course of (or “tanking” as NASA calls it) that launch controllers encountered an issue throughout the company’s first launch try on Monday (August 29). NASA canceled that take a look at launch when it couldn’t verify that one of many 4 RS-25 principal engines on the SLS core stage was at its correct coolant temperature of minus 420 levels Fahrenheit for launch.
The company finally decided {that a} unhealthy sensor was the supply of the issue and carried out workarounds for Saturday’s launch try. On Saturday, NASA deliberate to start the principle engine cooling course of earlier to offer the SLS rocket engines extra time to succeed in their goal temperature. However this course of was delayed by the gas leak.
NASA’s Artemis 1 mission is the primary take a look at flight of NASA’s Artemis program to return astronauts to the moon by 2025. The mission consists of a 37-day journey across the moon to confirm that the spacecraft Orion spacecraft and the SLS rocket are secure for astronauts. The mission may also deploy 10 Artemis cubesats on the best way to the moon and carry out a sequence of experiments to measure the expertise of astronauts on the Orion spacecraft.
Artemis 1 is about to return to Earth on October 11 with a dip within the Pacific Ocean off California. If all goes properly, NASA goals to launch a crewed orbit of the moon on the Artemis 2 mission in 2024, adopted by the Artemis 3 crewed lunar touchdown in 2025.
