NASA’s second Artemis I launch attempt in jeopardy

TITOSVILLE, Fla. (WFLA) — NASA’s second Artemis 1 mission launch attempt from Kennedy Space Center is now a “no” on Saturday.

The Artemis I mission management team attempts to launch the new Space Launch System (SLS) rocket and Orion spacecraft on Saturday afternoon. Artemis I will launch the SLS rocket – also known as the giant moon rocket – and send the Orion spacecraft on a 37-day, 1.3 million mile test flight around the moon.

But as the team prepared to start the mission on Saturday morning, they discovered a leak in the hydrogen line. NASA made three unsuccessful attempts to repair the leak.

“While refueling the Artemis 1 mission, the power side of the 8-inch quick disconnect leaked while trying to deliver fuel to the rocket,” NASA said. “So far, attempts to remedy this have failed. Hit.”

NASA’s launch team recommended “no” around 11 a.m., with a second official mission expected this week.The first launch attempt was canceled on Monday morningAfter NASA encountered several technical issues before the launch window.

What went wrong?

Task Manager Meet several times this week to discuss Monday’s issues And analyze the data recorded during the countdown period before the task is completed. The team decided to go ahead with the Saturday afternoon launch attempt. They have, however, updated their procedures and schedules in response to Monday’s major issue, where one of the rocket engines apparently did not cool enough to launch.

“The team will adjust the engine cool down procedure, also known as the start exhaust test, with a countdown of approximately 30 to 45 minutes during the liquid hydrogen rapid fill phase of the stage. central,” NASA explained. “This will allow more time to cool the engine down to the correct temperature for launch.”

SLS project manager John Honeycutt said he believed Monday’s problem was actually caused by a faulty sensor and said he was confident all four main motors were working fine.

“The way the sensor behaves does not correspond to reality,” he said.

Saturday Forecast

In a launch forecast released on Friday, US Space Force meteorologists said weather conditions near Kennedy Space Center appeared to be about 60% favorable by early Saturday afternoon. The situation should improve over time.

“This should allow east coast sea breezes to form scattered showers early Saturday afternoon, but gradually push activity westward away from the spaceport by late afternoon.” , according to forecasts. “The timing of the launch window will be during this transition period.”

Meteorologists say the main focus during the launch window will be cumulus rulers and surface electric field rulers.

“Basically, the weather looks good. I wouldn’t be shocked if there was a time when we were technically ‘red’ to the weather,” said Delta 45 space launch weather officer Melody Lovin on Thursday. “But most importantly, I don’t think the weather will be an obstacle.”

NASA has aList of meteorological standardsThis must be respected to continue shooting. The agency monitors temperature, wind, precipitation, lightning, clouds and solar activity.

If the launch has to be canceled again on Saturday, NASA could try again as early as Monday.

“As with all scrubs, it depends on what you are scrubbing for. It really boosts your transformation,” says Blackwell-Thompson. “But if it’s a climate issue, we’re driven by the replenishment of raw materials – hydrogen is the main driver. We can leave on Monday, so it’s a 48 hour delay.

Project Artemis

Launch pad 39B, the launch pad from which Artemis launched, is the same launch pad as Apollo 10. The Apollo program was the last time humans set foot on the moon there. is over 50 years old. In Greek mythology,Artemis was the twin sister of Apollo.

According to the new Project Artemis, NASA plans to land the first woman and first person of color on the moon. NASA is looking to establish a long-term presence on the lunar surface and use what it learns to eventually send astronauts to Mars.

Artemis I

Artemis I is NASA’s first step toward achieving the goals of the Artemis program. This is an unmanned mission, which means there will be no humans in flight. NASA calls it “the first in a series of increasingly complex missions aimed at establishing a long-term human presence on the Moon for decades to come.”

“The mission will demonstrate the capabilities of the SLS rocket and test the capabilities of Orion in approximately six weeks as it flies approximately 40,000 miles past the Moon and returns to Earth,” NASA explained.

NASA explains on its website that the primary objectives of the mission are to “demonstrate Orion’s systems in a spaceflight environment” and “to ensure safe reentry, descent, splashdown and recovery.” . This will help future missions, including Artemis II, which will be the program’s first crewed orbit around the moon.

Artemis I marks the first “integrated test” of NASA’s deep space exploration system. If the mission launches on Saturday, NASA will sputter on October 11.

deep space exploration system

The SLS and Orion rocket, along with ground systems at Kennedy Space Center, make up NASA’s deep space exploration system.

ThisSLS rocketDescribed by NASA as the most powerful rocket in the world. According to the agency, it is currently the only rocket capable of safely sending the Orion spacecraft to the Moon.

“The SLS is designed for manned space missions and will send the Orion spacecraft to the Moon nearly 1,000 times farther than the International Space Station in low Earth orbit,” NASA said. “The rocket will provide the power needed to help Orion reach speeds of 22,600 mph to escape Earth’s gravity [and] Send a spaceship to the moon. “

According to NASA, the Orion spacecraft will launch on an SLS rocket designed to take humans into deep space. It is “specifically designed to support humans hundreds of thousands of miles from home,” the agency said.
