NASA is taking another crack at fueling its giant moon rocket after leaks halted the initial dress rehearsal and delayed astronauts' first trip to the moon in more than half a century
CAPE CANAVERAL, Fla. -- NASA took another crack at fueling its giant moon rocket Thursday after leaks halted the initial dress rehearsal and delayed the first lunar trip by astronauts in more than half a century.
For the second time this month, launch teams began pumping more than 700,000 gallons (2.6 million liters) of supercold fuel into the rocket atop its launch pad.
It’s the most critical and challenging part of the two-day practice countdown. The outcome will determine whether a March launch is possible for the Artemis II moon mission with four astronauts.
During the rehearsal two weeks ago, dangerous amounts of supercold liquid hydrogen escaped from the connections between the pad and the 322-foot (98-meter) Space Launch System rocket. Engineers replaced a pair of seals and a clogged filter in hopes of getting through the repeat test at Kennedy Space Center.
NASA won’t set a launch date for the Artemis II mission until it passes the fueling demonstration. Like last time, the crew — three Americans and one Canadian — watched the test from afar.
