Live coverage: Vega rocket launches with LISA Pathfinder

The European Space Agency has cinched an agreement with Arianespace for the October 2018 launch of the James Webb Space Telescope aboard an Ariane 5 rocket, which will dispatch the nearly $10 billion observatory on a bold mission that promises to rewrite astronomy textbooks.

SpaceX launched a Falcon 9 rocket at 1:09 p.m. PDT (4:09 p.m. EDT) Wednesday from Vandenberg Space Force Base, California, on a mission hauling 51 more Starlink internet satellites into orbit.

Fifty years to the day after Neil Armstrong stepped onto the surface of the moon, a NASA astronaut, an Italian flight engineer and a Russian commander geared up for launch aboard a Soyuz spacecraft Saturday on a six-hour flight to the International Space Station.
