Photos: More Launch shots of Delta 375 rocket

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Thursday evening, heading due east over the Atlantic Ocean to deliver the BulgariaSat 1 communications satellite into orbit 35 minutes later.

A Russian-made Soyuz booster rolled out to its launch pad in French Guiana on Friday, and hydraulic lifts rotated the launcher vertical in preparation for liftoff Tuesday with the first in a new series of French military spy satellites.

Follow the key events of the Soyuz rocket’s ascent into orbit from the Guiana Space Center with the first COSMO-SkyMed Second Generation, or CSG 1, radar observation satellite, the European Space Agency’s CHEOPS exoplanet telescope, and three CubeSats.
