NASA's Artemis II crewed mission to the moon shows how U.S. space strategy has changed since Apollo -- and contrasts with China's closed program.

NASA plans to launch the Crew-12 mission earlier than intended after a medical evacuation at the ISS. But could the Artemis 2 mission delay it?

NASA's first tragedy is recalled annually at Launch Complex 34. This year is different, as the Artemis II mission sits on the horizon.

The first is the rapid rise of China’s space program, which only flew its first human to orbit in 2003 but now boasts spaceflight capabilities second only to the United States. The second trend is the rise of the commercial space sector, first in the United States and led by SpaceX, but now spreading across much of the planet.
