There was a groundbreaking Friday at Cape Canaveral’s Complex 41 to start building the astronaut access tower to board Boeing’s CST-100 capsules atop United Launch Alliance Atlas 5 rockets.

This photo gallery shows the commercial Cygnus cargo resupplier for the International Space Station on Monday at Kennedy Space Center being encapsulated in the United Launch Alliance Atlas 5 rocket’s payload fairing for the planned Dec. 3 liftoff.

Technicians inched the two halves of the Atlas 5’s aluminum nose cone around NASA’s OSIRIS-REx spacecraft to package the asteroid sample return probe, then moved the satellite to the rocket’s assembly building and hoisted it aboard the two-stage booster during the final days of August for the Sept. 8 launch.
