Robert Zubrin, the planet’s leading strategist for landing humans on Mars, predicts SpaceX’s Starship will win the race to speed astronauts to Mars, but not until 2031.

SpaceX launched another batch of Starlink satellites into orbit, a little more than 12 hours after the private company teamed up with NASA to send four astronauts to the International Space Station -- also from Florida.

NASA astronauts Sunita "Suni" Williams and Barry "Butch" Wilmore have been on the International Space Station for more than eight months, even though they initially expected to stay for just about eight days.

The crew-swap mission will enable NASA’s Butch Wilmore and Suni Williams to return to Earth from the International Space Station.
