Russia’s space agency says a Kazakh cosmonaut will fly to the International Space Station on 10-day mission in September, replacing British singer Sarah Brightman, who backed out of the mission in May.

Europe’s Rosetta spacecraft — six months into its mission at comet 67P/Churyumov-Gerasimenko — made its closest flyby of the comet’s boulder-strewn nucleus Saturday, capturing photos and measurements to help scientists unravel how the duck-shaped body is evolving on its path around the sun.

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 blasted off from Kazakhstan Saturday aboard a Soyuz spacecraft, chased down the International Space Station and glided in for a picture-perfect docking.
