Live coverage: Station crew lands in Kazakhstan

Soyuz commander Anatoly Ivanishin and flight engineers Kate Rubins of NASA and Takuya Onishi of JAXA conduct final qualification training at the Gagarin Cosmonaut Training Center for their flight to the International Space Station in June.

The International Space Station’s oldest sections launched nearly 17 years ago, and with the huge orbiting research complex now well into its operational life as a microgravity science lab, prime contractor Boeing’s job is keeping the outpost going, according to Mark Mulqueen, who manages the aerospace company’s space station program.

Boeing and NASA officials said Thursday the first launch of astronauts on Boeing’s delay-prone Starliner crew capsule won’t happen in July after engineers recently discovered a problem with the spacecraft’s parachute system and identified flammable tape around wiring harnesses inside the vehicle.
