Live coverage: Space station crew concludes 186 days in orbit

The final flight of a discontinued version of Europe’s Ariane 5 rocket added four more spacecraft to Europe’s Galileo navigation constellation Wednesday, giving the multibillion-euro network enough satellites to remain on track for the start of full global service in 2020.

Last week’s successful launch of a Vega rocket with a European re-entry technology demonstrator marked the first of at least 11 flights planned this year by Arianespace to put communications satellites, Earth observatories and research probes into space.

This is video footage documenting preparations for the commercial Orbital ATK Cygnus cargo freighter to perform the OA-7 mission to the International Space Station. Activities occurred at the Kennedy Space Center’s Space Station Processing Facility and the Payload Hazardous Servicing Facility. The craft will be boosted into orbit by a United Launch Alliance Atlas 5 rocket on April 18 at 11:11 a.m. EDT (1511 GMT).
