Video: Cygnus freighter arrives at orbital destination

SpaceX and NASA launched a planet-hunting satellite Wednesday from Cape Canaveral, two days after calling off a launch attempt to conduct additional guidance, navigation and control analyses. Liftoff occurred at 6:51 p.m. EDT (2251 GMT), and the first stage of the Falcon 9 rocket successfully landed on a drone ship in the Atlantic Ocean.

Lighting up the pre-dawn sky, a Soyuz rocket roared to life and streaked into orbit Tuesday carrying a Russian cosmonaut and two NASA astronauts to the International Space Station, boosting the lab’s crew back to six and the U.S. complement to four NASA-sponsored astronauts.

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.
