A United Launch Alliance Atlas 5 rocket took off Saturday from California with the InSight spacecraft heading for Mars.

An all-veteran crew of four astronauts jetted into NASA’s Kennedy Space Center Friday for the final few days of rehearsals, briefings, and relaxation before blasting off Thursday bound for a six-month stint on the International Space Station.

Two Russian cosmonauts stepped outside the International Space Station Wednesday, sent birthday greetings to former cosmonaut Alexey Leonov, the first man to walk in space, and then carried out a full slate of maintenance work.
