Video: Rosetta scientist Matt Taylor on the end of mission

A Russian Soyuz spacecraft streaked into space and chased down the International Space Station Tuesday, but a problem with the ferry ship’s automated rendezvous system forced commander Yuri Malenchenko to take over manual control at the last minute.

Five years after winning $1 billion from NASA to mount the first U.S. asteroid sample return mission, scientists and engineers will get their last look at the OSIRIS-REx spacecraft this week as it is closed up inside the nose cone of an Atlas 5 rocket for launch in September.

Ground crews have mounted the fully-fueled Sentinel 2B spacecraft, the next mission in Europe’s multibillion-dollar Copernicus Earth observation satellite fleet, on top of a Vega rocket inside a protective gantry on its launch pad in French Guiana for blastoff next month.
