The mission to the moon failed: NASA was unable to launch a rocket to the Earth's satellite

NASA's return to the moon has been delayed due to problems with one of the rocket's four main stage engines.

Engine 3 does not reach the proper temperature range required to start it. The process is carried out by feeding some cryogenic fuel into the engines, but this engine is generally out of the game.

All four R-25 engines from the rocket's main stage needed to be "conditioned" with cryogenic fuel to bring them up to the right temperature for launch, but one of the four did not fire as NASA expected, according to NASA. The Guardian.

The engine "didn't reach the temperature it needed," launch control communicator Darrol Neil said, adding that the rocket would remain refueled at Launch Pad 39B at the Kennedy Space Center in Florida while engineers collected data.

“The rocket is currently in a stable configuration,” he said. “The team was unable to cope with the engine bleed, which was not showing the correct temperature, and ultimately the launch director called a cancellation for the day.”

“We have to wait to see what comes out of their test data that they are collecting now and wait for the decision the launch team has to make on where to go next,” he said.

The countdown stopped at T minus 40 minutes for a while.

Engineers fixed one of the problems - a supposed crack in the fuel tank flange.

“There was a line of ice on the core stage inner tank where there is a flange,” Derrol Neil said. “Engineers took a long look and concluded that the ice that formed along the line was essentially air cooled by the reservoir that was getting into a crack in the foam, but not into the reservoir itself.”

But the problem with the engine turned out to be more complicated.

The next mission launch window is Friday, September 2nd. Artemis I has a two-hour launch window on this day, starting at 12:48 pm ET (16:48 pm UTC). The return of the mission will take place in 40 days, on October 11, as opposed to the 42-day mission if it was carried out today. If the launch is delayed further, the next window will begin on September 5 at 17:12 pm ET (21:12 pm UTC) and will last 90 minutes. Once launched, the mission will last 43 days, returning on October 17th.

NASA said it could not yet set a new launch date for the Artemis I rocket as it was "too early to talk about options," a spokesman for the canceled mission said. Independent.

After launch (whenever it takes place), the Orion capsule attached to Artemis I will spend six days of the mission in orbit around the moon. It will test important technologies, paving the way for Artemis II, the first manned mission to lunar orbit since Apollo 17 in 1972.

Various voices, including astronauts, senior NASA officials and others, explain why we are returning to the Moon and what we need to get there.

Bill Nelson, a NASA administrator and himself a former spacecraft astronaut, also laid out the rationale in an interview with NBC's Meet the Press on August 28. He said that the ultimate goal is to put people on Mars, and that returning to the Moon and building a base there is an important step towards that journey.

“We need to be on the Moon for much longer than just landing, as we are used to, staying for a couple of days and leaving. This time we will return, we will live there, we will study there. We are going to develop new technologies, all so that we can go to Mars with people,” he said. - All this should develop where we can live, on other planets. This could be the surface of Mars. But this is just part of our desire to go out, our desire to explore, to find out what is in the universe.”
