Live coverage: Soyuz crew arrives at International Space Station

The International Space Station’s crew will enjoy views of the Aug. 21 solar eclipse during three successive orbits, giving the astronauts a unique opportunity to take in the celestial show from 250 miles up as the moon’s shadow races across from the Pacific Ocean and the continental United States before moving out over the Atlantic.

A previously-flown SpaceX Falcon 9 rocket booster conducted a test-firing Monday at NASA’s Kennedy Space Center in Florida, ahead of a planned launch Oct. 7 with an Airbus-built communications satellite made for SES and EchoStar.

Technicians working at launch pad 0A at NASA’s Wallops Flight Facility in Virginia completed the final loading of cargo into Northrop Grumman’s Cygnus supply ship late Tuesday, and the Antares rocket was raised vertical again in preparation for Wednesday’s countdown.
