Live coverage: International Space Station crew lands in Kazakhstan

International Space Station commander Jeff Williams set a new U.S. space endurance record Wednesday, his 521st day in orbit over four missions, eclipsing the 520-day record set earlier this year by astronaut Scott Kelly at the end of his nearly one-year stay aboard the lab complex.

Former astronaut Bruce McCandless II, a retired Navy captain and son of a Medal of Honor winner who joined NASA during the buildup to the Apollo program, served as capsule communicator when Neil Armstrong took his historic first step on the moon and later flew in space twice during the shuttle program, died Thursday. He was 80.

After a four-day delay due to a ground power supply anomaly and unfavorable weather, an Ariane 5 rocket lifted off at 4:23 p.m. EST (2123 GMT) Tuesday to send into orbit a hush-hush communications satellite for the Egyptian military and a spacecraft to expand the capacity of Inmarsat’s mobile Internet service.
