Snapshots from Atlas 5 launch

Signs that a launch to the International Space Station is approaching are obvious this week at Cape Canaveral, with the Atlas 5 booster rocket beginning to take shape and the commercial resupply ship heading to its propellant depot.

Narrated video packages show the shrouded NROL-37 payload being hoisted atop the United Launch Alliance Delta 4-Heavy rocket and the retraction of the mobile service gantry.

The robotic lander will attempt to touch down on the lunar surface at Mare Crisium near Mons Latreille Sunday morning. The anticipated landing time is no earlier than 3:34 a.m. EST (0834 UTC).
