Live coverage: SpaceX launches another batch of Starlink satellites

As Orbital ATK engineers aim for the next launch of the company’s Antares rocket from Virginia this fall, early planning for missions to keep the International Space Station supplied through the early 2020s is already underway.

This mission was the second of two Falcon 9 flights on Sunday night. Liftoff from SLC-4E at Vandenberg Space Force Base occurred at 9:09 p.m. PDT (12:09 a.m. EDT, 0409 UTC).

Tyvak, a manufacturer of small satellites, disclosed new details Monday about an experimental spacecraft launched aboard a SpaceX Falcon 9 rocket Saturday, revealing plans to validate compact optical telescopes that could offer a new way to monitor space traffic and orbital debris.
