NASA has postponed the pivotal fueling test for Artemis II because of a near-freezing chill in Florida, making a February space launch far less likely.

As early as Sunday, Feb. 8, the rocket could provide the initial burst of thrust to propel the crew of Artemis 2 into space on the first human lunar spaceflight in more than 50 years.

The second flight under NASA's multibillion-dollar lunar program, Artemis 2 will send three Americans and one Canadian on a 10-day trip around the moon.
