Live coverage: SpaceX launches another batch of Starlink satellites

China successfully launched a Gaofen optical observation satellite Sunday toward a perch more than 22,000 miles over the equator, where it will use an Earth-facing telescope to collect remote sensing images, Chinese state media said.

NASA has agreed to consider a Boeing proposal to extend the first piloted test flight of its commercial CST-100 Starliner crew capsule from two weeks to up to six months with an extra crew member for the International Space Station, hedging against potential delays that could jeopardize U.S. crew access to the orbiting outpost.

The Centaur upper stage launching the Cygnus space freighter Tuesday persevered through a velocity shortfall from the first stage of the Atlas 5 rocket, improvising with a longer firing to reach the correct orbit.
