4K video: Wide-angle view of Falcon 9 hotfire

A Polar Satellite Launch Vehicle lifted off Friday with 31 satellites on the first flight for India’s workhorse rocket since an August mishap that left an Indian navigation satellite unusable after reaching orbit.

NASA astronaut Nick Hague and Roscosmos cosmonaut Alexandr Gorbunov walked through a launch day simulation as NASA and SpaceX prepared to conduct a static fire test of the Falcon 9 rocket. Ignition happened at 10:05 p.m. EDT (0205 UTC).

The mission will focus on proving the reusability of the rocket and not on additional flight objectives, like operating the payload bay door or reigniting the vacuum engines on the Ship upper stage. The June 5 launch window opens at 7 a.m. CDT (8 a.m. EDT (1200 UTC).
