Q&A with Curt Blake, president of Spaceflight Industries (members only)

SpaceX put on hold its plan to launch a Falcon 9 rocket from NASA’s Kennedy Space Center and rescheduled it for no earlier than Wednesday. Liftoff is scheduled for 7:19 a.m. EST (1219 UTC) at the earliest.

A week after a test-firing of SpaceX’s new crew capsule went awry, SpaceX successfully completed a hold-down firing of its next Falcon 9 launcher Saturday morning at Cape Canaveral in preparation for a predawn liftoff Wednesday carrying several tons of food, supplies and experiments to the International Space Station.

An Indian Polar Satellite Launch Vehicle, crowned with 31 satellites from 15 countries, is counting down to liftoff early Friday from an island spaceport on the country’s east coast.
