Artemis, Orion and the quest to get humans to the moon again A virtual tour of European Service Modules headed for the moon on NASA's human spaceflight program Artemis is not what it seems.

A cleanroom is a surreal space inhabited almost exclusively by enthusiastic men If you've ever been on a tour of a cleanroom — a sterile environment where engineers build and test satellites and other spacecraft — you will know it's a pretty surreal experience.
