No moon shot today: NASA's launch delayed by a leaky engine

The Space Launch System rocket set to lift off Monday from Florida with three test dummies aboard has been postponed. NASA hopes to send four astronauts around the moon in 2024 and land humans there as early as 2025.

NASA’s new moon rocket was scheduled to blast off from Florida's Kennedy Space Center on Aug. 29, but the launch has been delayed due to a fuel leak and engine troubles.

A fuel leak and then an engine problem during final liftoff preparations led NASA to call off the launch of its mighty new moon rocket Monday on its debut flight with three test dummies aboard.

The next launch attempt will not take place until Friday at the earliest and could be off until next month.

The flight, when it happens, will be the first launch in NASA’s Artemis project, a quest to put astronauts back on the moon for the time since the Apollo program ended 50 years ago.

As precious minutes ticked away Monday morning, NASA repeatedly stopped and started the fueling of the Space Launch System rocket with nearly 1 million gallons of super-cold hydrogen and oxygen because of a leak of highly explosive hydrogen. The leak happened in the same place that saw seepage during a dress rehearsal back in the spring.

Then, NASA ran into new trouble when it was unable to properly chill one of the rocket’s four main engines, officials said. Engineers continued working to pinpoint the source of the problem after the launch postponement was announced.

“This is a very complicated machine, a very complicated system, and all those things have to work, and you don’t want to light the candle until it’s ready to go,” said NASA Administrator Bill Nelson.

Referring to launch delays, Mr. Nelson said: “It’s just part of the space business and it’s part of, particularly, a test flight.”

The rocket was set to lift off on a flight to propel a crew capsule into orbit around the moon. The six-week mission was scheduled to end with the capsule returning to Earth in a splashdown in the Pacific in October.

The 322-foot (98-meter) spaceship is the most powerful rocket ever built by NASA, out-muscling even the Saturn V that the Apollo astronauts rode.

As for when NASA might make another liftoff attempt, launch commentator Derrol Nail said engineers were still analyzing the engine problem and “we must wait to see what shakes out from their test data.”

No astronauts were inside the rocket’s Orion capsule. Instead, the test dummies, fitted with sensors to measure vibration, cosmic radiation, and other conditions, were strapped in for the shakedown flight, meant to stress-test the spacecraft and push it to its limits in ways that would never be attempted with humans aboard.

Even though no one was on board, thousands of people jammed the coast to see the rocket soar. Vice President Kamala Harris was among the VIPs who arrived for the event.

Assuming the shakedown flight goes well, astronauts will strap in for the second mission and fly around the moon and back as soon as 2024. A two-person lunar landing could follow by the end of 2025.

The problems seen Monday were reminiscent of NASA’s space shuttle era, when hydrogen fuel leaks disrupted countdowns and delayed a string of launches back in 1990.

Later in the morning, NASA also officials spotted what they feared was a crack or some other defect on the core stage – the big orange fuel tank with four main engines on it – but they later said it appeared to be just a buildup of frost in a crevice of the insulating foam.

Launch director Charlie Blackwell-Thompson and her team also had to deal with a communication problem involving the Orion capsule.

Engineers scrambled to understand an 11-minute delay in the communication lines between launch control and Orion that cropped up late Sunday. Though the problem had cleared by Monday morning, NASA needed to know why it happened before committing to a launch.

Regardless of all the technical snags, thunderstorms ultimately would have prevented a liftoff. Dark clouds gathered over the launch site as soon as Blackwell-Thompson halted the countdown, with thunder echoing across the coast.

What is the Monitor difference? Tackling the tough headlines – with humanity. Listening to sources – with respect. Seeing the story that others are missing by reporting what so often gets overlooked: the values that connect us. That’s Monitor reporting – news that changes how you see the world.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
