The towering rocket NASA will use to help propel four astronauts on a historic trip around the moon is vertical on the launch pad, and you can see it anytime.

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.

NASA has decided to bring the Crew-11 astronauts home a month earlier than originally planned due to a "medical concern" with one of them.
