NASA Postpones Artemis I Mission Again Due to Fuel Leak Hours Before Scheduled Launch

A full Moon is in view from Launch Complex 39B at NASA’s Kennedy Space Center in Florida on June 14, 2022. The Artemis I Space Launch System (SLS) and Orion spacecraft, atop the mobile launcher, are being prepared for a wet dress rehearsal to practice timelines and procedures for launch. The first in an increasingly complex series of missions, Artemis I will test SLS and Orion as an integrated system prior to crewed flights to the Moon. Through Artemis, NASA will land the first woman and first person of color on the lunar surface, paving the way for a long-term lunar presence and using the Moon as a steppingstone on the way to Mars.

Artemis I is grounded once again.

NASA postponed its mission to the moon Saturday due to a fuel leak hours before the scheduled launch at Kennedy Space Center in Florida, after the original launch was scrubbed earlier this week because of engine issues.

"During tanking of the #Artemis I mission, a leak developed in the supply side of the 8-inch quick disconnect while attempting to transfer fuel to the rocket," NASA announced on Twitter. "Attempts to fix it so far have been unsuccessful."

They provided another update an hour later: "The #Artemis I mission to the moon has been postponed. Teams attempted to fix an issue related to a leak in the hardware transferring fuel into the rocket, but were unsuccessful. Join NASA leaders later today for a news conference."

At the heart of the Artemis I mission are the Orion, NASA's reusable spacecraft, and the agency's Space Launch System (SLS), the first rocket in half a century designed to fly astronauts to the Moon.

According to NASA, the Orion and SLS will fly 280,000 miles from Earth, and thousands of miles past the moon, during a six-week journey.

Once the Orion reaches the moon, the spacecraft will stay in orbit for about six days to collect data and allow mission controllers to test the spacecraft's performance. It will then set a path back to Earth.

During this time, the spacecraft will have remained in space "longer than any ship for astronauts has done without docking to a space station and return home faster and hotter than ever before," NASA said on its website.

NASA's Artemis I flight test is the first integrated test of the agencys deep space exploration systems: the Orion spacecraft, SLS rocket, and supporting ground systems. Launch of the uncrewed flight test is targeted for no earlier than Aug. 29 at 8:33 a.m. ET.

Artemis 1 is the first of a series of missions planned by NASA in the coming years to expand "human existence to the moon and beyond," per the space agency.

The Artemis mission was named after the Greek goddess of the moon, who is also the twin sister of Apollo, the god of sun and light. Apollo was also the name given to the series of missions that eventually led to astronauts Buzz Aldrin, Neil Armstrong, and Michael Collins reaching the Moon in 1969.

For the second Artemis mission, NASA plans to send astronauts on a different trajectory than the current mission with the goal of testing "Orion's critical systems with humans aboard," according to their website.

In future missions, NASA plans to land the first woman and first person of color on the moon, which could happen as soon as 2025, per National Geographic. These missions would be the first time NASA sent humans to the Moon since Apollo 17 in December 1972.

The objective of the Artemis missions is to create a long-term, sustainable lunar presence — while also serving as a foundation to eventually send astronauts to Mars, in addition to the moon.
