NASA's Artemis II rocket successfully completed a major prelaunch test. The crew will now enter quarantine as potential launch dates come as early as March.

NASA said that it will roll the SLS rocket and Orion spacecraft for Artemis II off the launch pad at the agency’s Kennedy Space Center in Florida as soon as Tuesday, Feb. 24. ・NASA’s Jared Issacman said that this will “assuredly impact” the March launch window.
