Cape Canaveral, Fla.: NASA aimed to launch a Crescent rocket on Saturday after fixing a fuel leak and circumventing a bad engine sensor that thwarted the first attempt.

The maiden flight of the 322-foot rocket, the most powerful NASA has ever built, was delayed late Monday’s countdown. The clocks at Kennedy Space Center started ticking again as administrators expressed confidence in their plans and forecasters indicated the odds of fair weather.

At the top of the rocket is a crew capsule with three test dummies that will fly around the moon and back over the course of six weeks. This is his first NASA attempt since the Apollo program 50 years ago. NASA wants to squeeze out the spacecraft before it puts astronauts on its next flight, scheduled in two years.

“This is a test flight, right? And I’m very happy with our procedures, but in the eyes of the team, they’re ready. We can’t control the weather.” ‘, said NASA’s Jeremy Parsons, Exploration Ground Systems, Friday.

Engineers in charge of the Space Launch Systems rocket claimed Thursday night that all four main engines were fine, with one of them appearing too warm on Monday due to a faulty temperature sensor. The engine must match minus 420 degrees Fahrenheit (minus 250 degrees Celsius) for liquid hydrogen fuel at takeoff. Otherwise, it may break and stop during flight.

Rocket program manager John Honeycutt said:

When refueling begins Saturday morning, the launch team will conduct another engine test – this time early in the countdown. Even if that suspect sensor indicates that one engine is too hot, he uses the other to make sure everything is working properly and count down if something goes wrong could be stopped, Honeycutt told reporters.

NASA was unable to perform that kind of engine test during dress rehearsals earlier this year because of a fuel leak. More fuel leaks occurred on Monday. A technician found the connections loose and tightened them.

The $4.1 billion test flight is NASA’s first step toward sending astronauts to the moon in 2024 and landing on the moon in 2025. The last time an astronaut walked on the moon was in 1972.
