With the wet dress rehearsal, essentially a critical fueling test of the Artemis 2 Space Launch System moon rocket, now back on Feb. 2, NASA said in a statement that it can no longer target Feb. 6 or Feb. 7, the first two days of its launch window. The Artemis 2 launch window originally ran from Feb. 6 to Feb. 10.

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. Already in quarantine to avoid germs,

NASA spent roughly a billion dollars to send a car‑sized robot into the Sun’s atmosphere, and to get there it had to accelerate to about 400,000 mph, faster than any spacecraft in history. That extreme journey has now paid off with the closest images ever taken of our star and a trove of data from
