Satellite Quartet: NASA's Magnetospheric Multiscale Mission in Pictures

Atlas V MMS Launch Photography

Calla Cofield,

More than a dozen photographers set up cameras only a few hundred feet from the Atlas V rocket that is set to launch today (March 12). To protect the cameras from heat and rain, the photographers build their own protection devices; here, cameras are protected by white cloth, black plastic boxes, poster board and garbage bags.

NASA MMS Satellites Launch Pad

A United Launch Alliance Atlas V rocket carrying NASA's four Magnetospheric Multiscale mission satellites rolls out to the launch pad at Cape Canaveral Air Force Station in Florida one day before its planned March 12, 2015 launch. The mission will study magnetic reconnections in Earth's magnetic field to better understand solar storms.
