Live coverage: Vega rocket launches with LISA Pathfinder

Russian commander Alexey Ovchinin, NASA co-pilot Nick Hague and astronaut Christina Koch lifted off aboard a Soyuz rocket Thursday from the Baikonur Cosmodrome in Kazakhstan, heading for the International Space Station to raise the research outpost’s crew complement back to six. The Soyuz booster launched at 1914 GMT (3:14 p.m. EDT), and docking at the space station occurred at 0101 GMT (9:01 p.m. EDT).

The James Webb Space Telescope is at risk of another launch delay beyond the mission’s current target launch date in March 2021, the Government Accountability Office said this week.

SpaceX intends to cut the price of a Falcon 9 rocket launch by up to 30 percent when flying with reused first stage boosters, an achievement the company still hopes to demonstrate before the end of the year, SpaceX’s president said recently.
