Live coverage: Four astronauts return home after 167 days in space

Four days after a picture-perfect blastoff from southern Japan, a cargo-carrying supply freighter arrived at the International Space Station on Tuesday with 4.5 tons of equipment, food, clothing and experiments.

This is the launch timeline to be followed by the Atlas 5 rocket’s ascent into space from Cape Canaveral with NASA’s Mars 2020 mission.

SpaceX’s first Falcon Heavy rocket took off on its inaugural test launch from NASA’s Kennedy Space Center in Florida at 3:45 p.m. EST (2045 GMT). The high-power launcher successfully boosted Elon Musk’s electric Tesla sports car into deep space as a shakedown for future Falcon Heavy missions.
