how fast is artemis 2

Artemis II is very fast: NASA’s mission materials and recent coverage indicate it reaches about 28,160 km/h (17,500 mph) in Earth orbit, then about 40,200 km/h (25,000 mph) on reentry.

Quick Scoop

• Around Earth: about 17,500 mph once the main engine cutoff stage is reached.

• On return to Earth: about 25,000 mph , which would make the crew the fastest humans in history during reentry.

• Launch acceleration: it gets to about 3,100 mph just after booster separation early in ascent.

What that means

Artemis II is not “fast” in the everyday sense so much as astronomically fast —fast enough to reach orbit and then travel to the Moon on a 10-day crewed flyby mission. If you want, I can also break down how fast it is compared with Apollo 10 or Artemis I.
