Live coverage: Vega rocket launches with LISA Pathfinder

Seven Japanese and Vietnamese smallsats are set to ride Japan’s solid-fueled Epsilon launcher into orbit at 0050 GMT Friday (7:50 p.m. EST Thursday) on a mission that engineers say will demonstrate the light-class rocket’s ability to accommodate multiple payloads on a single flight.

Veteran Russian cosmonaut Oleg Kononenko, flanked by Japanese flight engineer Kimiya Yui and NASA astronaut Kjell Lindgren, boarded a Soyuz landing craft Friday and made a parachute-assisted touchdown in Kazakhstan at 1312 GMT (8:12 a.m. EST) to close out more than 141 days on the International Space Station.

Blaming a slew of technical snags and “avoidable errors,” NASA officials said Tuesday that the launch of the James Webb Space Telescope, already years behind schedule, will be delayed to 2020, potentially pushing the mission’s development cost above an $8 billion cap mandated by Congress.
