NASA is planning to conduct a critical fueling test known as a wet dress rehearsal that will determine if Artemis 2 is on track to launch in Florida.

NASA began a two-day practice countdown Saturday leading up to the fueling of its new moon rocket, a crucial test that will determine when four astronauts blast off on a lunar flyby.

NASA's Artemis II mission reached a critical milestone this week as teams conducted a wet dress rehearsal of the Space Launch System rocket and Orion spacecraft during an unusually intense blast of cold air surged across Florida, delivering record-breaking low temperatures to the Sunshine State.

The countdown for NASA’s next trip around the Moon has shifted from planning to practice, as controllers begin a high‑stakes fueling rehearsal for the Artemis 2 Space Launch System. The wet dress test is designed to push the rocket and ground systems through a full launch‑day script,

If the fueling test goes well, the Artemis II flight around the moon and back could take off as early as Feb. 8.

NASA has run into exasperating fuel leaks in a make-or-break test of the moon rocket that's supposed to send astronauts on a lunar fly-around.
