Q&A with Jamie Bock, principal investigator of NASA’s SPHEREx mission (members only)

Spaceflight Now recently sat down with George Whitesides, chief executive of Virgin Galactic, to discuss the company’s recovery from a fatal crash of its SpaceShipTwo rocket plane on a test flight last year and get an update on its air-launched rocket designed to carry small satellites into orbit.

Orbital ATK transferred an Antares rocket and Cygnus supply ship to their launch pad on Virginia’s Eastern Shore late Thursday for a liftoff now targeted for Monday with nearly 7,400 pounds of cargo heading for the International Space Station.

This video replay shows the liftoff of SpaceX’s Falcon Heavy rocket from the Kennedy Space Center in Florida with 5.1 million pounds of thrust, followed by the nearby landing of the launcher’s twin side boosters nine minutes later. The rocket’s center core missed a landing attempt on SpaceX’s offshore drone ship.
