How will Artemis 2 astronauts exercise on the way to the moon?

Artemis 2 astronauts are preparing for the first moon excursion since 1972 that will have humans on board.

The Artemis 2 crew will spend 30 minutes daily doing squats and deadlifts using cables on the flywheel.

The flywheel is tiny, smaller than a carry-on suitcase airlines typically allow in the passenger cabin.

Orion only has 316 cubic feet ( 8.9 cubic meters ) of space in it.

Hirsch : Exercise data will fortify the spacecraft design against risky vibrations ahead of more ambitious moon-landing missions later in the decade .

Hirsch said the data will help fortify Artemis 2 , which will launch in 2018 .

Howell 's latest book, " Why Am I Taller ?", is co-written with astronaut Dave Williams .
