Live coverage: Vega rocket launches with LISA Pathfinder

A Proton rocket lifted off from the Baikonur Cosmodrome in Kazakhstan with the Spektr-RG X-ray astronomy mission at 1230:57 GMT (8:30:57 a.m. EDT) Saturday.

Most parts of the joint European-Russian ExoMars lander and rover are nearly ready for launch, but trouble with parachutes, electronics, software and concerns about the growing coronavirus pandemic have delayed the mission’s departure to Mars from this year until 2022, officials announced Thursday. 

A Soyuz booster set for liftoff Wednesday with a Russian cosmonaut, a German flight engineer, and a former NASA flight surgeon heading for the International Space Station arrived at its launch pad in Kazakhstan Monday.
