CAPE CANAVERAL, Fla. — The space agency started a new practice countdown on Tuesday for its historic moon mission carrying astronauts, following repairs to address hazardous fuel leaks that have pushed the launch date to March.
Two weeks earlier, the initial fueling trial was stopped due to liquid hydrogen leaks similar to those that caused problems during the Artemis program’s unmanned debut mission three years prior.
At Kennedy Space Center, where the massive lunar rocket is positioned, crews installed new seals and replaced a blocked filter before restarting the countdown sequence. This two-day trial will reach its peak on Thursday when teams attempt to load fuel into the rocket’s tanks. The four crew members selected for Artemis II will observe this critical practice run from a distance.
NASA requires a successful test without any leaks before announcing an official launch date. The Space Launch System rocket could potentially lift off as early as March 6. Agency officials had briefly considered advancing the date by three days but decided additional time was necessary to evaluate the fueling test data.
The most recent crewed lunar mission took place in 1972 as part of NASA’s Apollo program.
