NASA ran into a leak while fueling its new moon rocket Monday in one final make-or-break test that will determine when astronauts can launch on a lunar fly-around. The launch team began loading the 322-foot (98-meter) rocket with super-cold hydrogen and oxygen at Kennedy Space Center at midday.

NASA muscled through familiar headaches Monday at Kennedy Space Center during a critical tanking test dealing with liquid hydrogen leaks at the launch pad for the Artemis II moon mission that could fly as soon as this Sunday.

NASA begins Artemis II wet dress rehearsal, fueling the SLS and Orion ahead of a possible Feb. 8 launch window.

NASA teams worked through technical issues Monday as they conducted a high-stakes dress rehearsal for the Artemis II mission at Kennedy Space Center, a critical test ahead of the planned crewed flight around the moon.

Preparations are underway to begin critical testing of NASA spacecraft for the Artemis II mission that will send four astronauts around the moon. Fuel testing is set to begin Monday, NASA says. The fueling phase of prelaunch testing known as a "wet dress rehearsal" was delayed because of freezing temperatures at the launch pad located at NASA's Kennedy Space Center in Florida.

Dr. Addie Dove, the Physics Department Head and Professor at UCF joins FOX 35's Garrett Wymer live via Zoom to break down NASA's wet dress rehearsal for the Artemis 2 rocket and whether the intense cold snap could delay the mission again as we get closer to the launch window for the latest moon mission from Florida's Space Coast at Cape Canaveral.
