NASA's Artemis Moon Rocket: A Second Chance at Success
CAPE CANAVERAL, Fla. (AP) - NASA is giving its giant moon rocket another shot at fueling, a crucial step towards the Artemis II mission. This comes after a series of leaks halted the initial dress rehearsal, delaying the first lunar trip by astronauts in over half a century. The rocket, standing at 322 feet tall, requires more than 700,000 gallons of supercold fuel for liftoff. The process is a two-day practice countdown, with the outcome determining the March launch possibility for the Artemis II mission carrying four astronauts.
During the previous rehearsal, dangerous amounts of supercold liquid hydrogen escaped from the connections between the launch pad and the rocket. Engineers replaced seals and a clogged filter, aiming to address the issue for the repeat test. The crew, including three U.S.-Canadian members, joined the launch team to monitor progress. The astronauts' soonest launch date is set for March 6, a 10-day out-and-back trip to the moon, a feat not seen since Apollo 17 in 1972.
NASA's battle with hydrogen fuel leaks dates back to the space shuttle era, which supplied many of the SLS engines. The first Artemis test flight, without astronauts, faced months of grounding due to leaking hydrogen before finally launching in November 2022. NASA's new administrator, Jared Isaacman, a tech entrepreneur, has promised to redesign the fuel connections before the Artemis III mission, aiming to land two astronauts near the moon's south pole. Isaacman emphasizes safety, stating, 'We will not launch unless we are ready, and the safety of our astronauts will remain the highest priority.'
The fueling test on Thursday was a critical moment, with Isaacman releasing a report on Boeing's Starliner capsule program, criticizing its handling of a crisis that could have led to crew loss. This incident highlights the ongoing challenges NASA faces in ensuring the safety of its astronauts and missions.
