Snapshots: Soyuz takes off

The second set of Iridium’s next-generation satellites to launch on a SpaceX Falcon 9 rocket were prepared for liftoff inside a climate-controlled clean room at Vandenberg Air Force Base over the last few weeks.

Three heavy-duty Antonov cargo planes flew components of Europe’s ExoMars orbiter and lander from Italy to the Baikonur Cosmodrome in Kazkhastan last week, setting up for a March 14 launch toward the red planet.

The MS-25 mission was scrubbed on Thursday, but the root cause is still under investigation. The earliest that liftoff from the Baikonur Cosmodrome can now occur is Saturday, March 23, pending the outcome of the investigation.
