Live coverage: U.S.-Russian-Italian crew arrives at space station

Two software errors detected after launch of a Boeing Starliner crew ship during an unpiloted test flight last December, one of which prevented a planned docking with the International Space Station, could have led to catastrophic failures had they not been caught and corrected in time, NASA said Friday.

A nearly 180-foot-tall (54.8-meter) Ariane 5 rocket rolled out of its integration hangar to the ELA-3 launch zone Wednesday at the Guiana Space Center in South America, moving into position for liftoff Thursday with two geostationary communications satellites.

A Soyuz rocket delivered a Russian military intelligence satellite to orbit Thursday after lift off from the Plesetsk Cosmodrome in Russia’s far northern Arkhangelsk region, the first flight of a Soyuz variant since an aborted crew launch earlier this month.
