A United Launch Alliance Atlas V 421 will launch the Magnetospheric Multiscale (MMS) mission for NASA.

Date/Site/Launch Time: Thursday, March 12, 2015, from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida. The 30-minute launch window opens at 10:44 p.m. EDT.

Mission Description: The Magnetospheric Multiscale, or MMS, mission studies the mystery of how magnetic fields around Earth connect and disconnect, explosively releasing energy via a process known as magnetic reconnection. MMS consists of four identical spacecraft that work together to provide the first three-dimensional view of this fundamental process, which occurs throughout the universe.

Launch Notes: MMS will be United Launch Alliance’s 94th launch since the company was founded in December 2006. It will mark the third of 13 planned ULA missions in 2015.
