Back to GRAIL photos

The Mobile Service Tower at Complex 17 Pad B rolls back in this nighttime time-lapse photo taken late in the evening before the first launch attempt, September 8. This is the final Delta mission from Complex 17 after nearly six decades of launches from this, the oldest active pad still in use at Cape Canaveral. Complex 17 saw its first launch in January 1957, from Pad B, and its first space launch in 1960 when Echo 1, the world's first communications satellite, failed to make orbit on what was the first Delta vehicle by name, having been transitioned from the Thor IRBM.
