Engine Problem Leads NASA to Scrub Artemis 1 Launch

CAPE CANAVERAL, Fla.: A gas leak after which an engine drawback throughout closing liftoff preparations led NASA to wash the launch of its mighty new moon rocket Monday morning on a shakedown flight with three take a look at dummies aboard.

The subsequent launch try won’t happen till Friday on the earliest.

As treasured minutes ticked away, NASA repeatedly stopped and began the fueling of the House Launch System rocket with almost 1 million gallons of super-cold hydrogen and oxygen due to a leak of extremely explosive hydrogen in the identical place that noticed seepage throughout a gown rehearsal again within the spring.

Then, NASA bumped into new bother when it was unable to correctly chill one of many rocket’s 4 major engines, officers mentioned. Engineers continued working to collect knowledge and pinpoint the supply of the issue after the launch postponement was introduced.

The rocket was set to raise off on a mission to place a crew capsule into orbit across the moon. The launch represents a milestone in America’s quest to place astronauts again on the lunar floor for the primary time for the reason that Apollo program ended 50 years in the past.


The 322-foot (98-meter) spaceship is probably the most highly effective rocket ever constructed by NASA, out-muscling even the Saturn V that took the Apollo astronauts to the moon.

As for when NASA may make one other launch try, launch commentator Derrol Nail mentioned the issue was nonetheless being analyzed, and “we should wait to see what shakes out from their take a look at knowledge.”

No astronauts had been contained in the rocket’s Orion capsule. As an alternative, the take a look at dummies, fitted with sensors to measure vibration, cosmic radiation and different circumstances, had been strapped in for the six-week mission, scheduled to finish with the capsule’s splashdown within the Pacific in October.

Though nobody was on board, hundreds of individuals jammed the coast to see the rocket soar. Vice President Kamala Harris was anticipated among the many VIPs.

The launch, when it occurs, would be the first flight in NASA’s Twenty first-century moon-exploration program, named Artemis after Apollo’s mythological twin sister.

Assuming the take a look at goes properly, astronauts will climb aboard for the second flight and fly across the moon and again as quickly as 2024. A two-person lunar touchdown might observe by the tip of 2025.

The issues seen Monday had been harking back to NASA’s house shuttle period, when hydrogen gas leaks disrupted countdowns and delayed a string of launches again in 1990.

Later within the morning, NASA additionally officers noticed what they feared was a crack or another defect on the core stage — the massive orange gas tank with 4 major engines on it — however they later mentioned it seemed to be only a buildup of frost.

Launch director Charlie Blackwell-Thompson and her group additionally needed to cope with a communication drawback involving the Orion capsule.

Engineers scrambled to grasp an 11-minute delay within the communication traces between launch management and Orion that cropped up late Sunday. Although the issue had cleared by Monday morning, NASA wanted to know why it occurred earlier than committing to a launch.
