launch window opens at 6:46:17 pm ET on February 25. The satellite will be deployed approximately 31
minutes after liftoff.

This mission is going to a Geostationary Transfer Orbit. Following stage separation, the first stage of the
Falcon 9 will attempt an experimental landing on the “Of Course I Still Love You” droneship. Given this
mission’s unique GTO profile,
a successful landing is not expected.
