Snapshots from Atlas 5 launch

A United Launch Alliance Atlas 5 rocket is set to roll to its launch pad Wednesday at Cape Canaveral, a day before liftoff with a new-generation NOAA weather satellite. The launch of a SpaceX Falcon 9 rocket with a Spanish communications satellite is expected to be shuffled after the Atlas 5 flight in a rapid-fire launch sequence at the Florida spaceport this week.

As NASA turns up support for future commercial lunar landers, the space agency last week canceled a mission that would have placed a rover on the moon to survey resources, such as water and helium, that could be used by future human explorers.

The launch will be preceded by a company talk from Elon Musk, discussing SpaceX’s plans for developing the rocket for Mars exploration. Launch teams are targeting a liftoff from Pad A at Starbase, Texas, on Tuesday, May 27, at 6:30 p.m. CDT (7:30 p.m. EDT, 2330 UTC).
