[SatNews] A United Launch Alliance (ULA) Atlas V rocket carrying the Magnetospheric Multiscale (MMS) payload for NASA lifted off from Space Launch Complex-41 at 10:44 p.m. EDT on March 12. This launch marks ULA’s third launch of 13 planned for 2015, and the 94th successful mission since the company was formed.
“It is our honor to launch this mission that will study the physics of magnetic reconnection. This energy process is one of the key drivers of space weather which affects communication networks, like GPS navigation and electrical power grids here on Earth,” said Jim Sponnick, ULA vice president, Atlas and Delta Programs. “Congratulations to the NASA Launch Services Program team, the NASA Goddard Space Flight Center team, Southwest Research Institute, all of our mission partners and the entire MMS team on this successful launch of the MMS constellation.”
This mission was launched aboard an Atlas 421 configuration vehicle, which includes a 4-meter-diameter payload fairing along with two Aerojet Rocketdyne solid rocket boosters attached to the Atlas booster. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine, and the Centaur upper stage was powered by the Aerojet Rocketdyne RL10A engine. This is ULA’s forth launch of the 421 configuration, and NASA’s 12th mission to launch on an Atlas V rocket.

MMS is a NASA Solar Terrestrial Probes mission consisting of four identical science observatories whose objective is to understand the microphysics of magnetic reconnection. The four MMS observatories are designed, built and operated by NASA’s Goddard Space Flight Center (GSFC) in Greenbelt, Maryland and a science and instrument team led by Southwest Research Institute (SwRI) in San Antonio, Texas.
ULA's next launch is the Delta IV GPS IIF-9 mission for the United States Air Force, scheduled for March 25 from Space Launch Complex-37 from Cape Canaveral Air Force Station, Florida.
With more than a century of combined heritage, United Launch Alliance has successfully delivered more than 90 satellites to orbit that provide critical capabilities for troops in the field, aid meteorologists in tracking severe weather, enable personal device-based GPS navigation and unlock the mysteries of our solar system.
NASA's Information
Following a successful launch at 10:44 p.m. EDT Thursday, NASA’s four Magnetospheric Multiscale (MMS) spacecraft are positioned in Earth’s orbit to begin the first space mission dedicated to the study of a phenomenon called magnetic reconnection. This process is thought to be the catalyst for some of the most powerful explosions in our solar system.
The spacecraft, positioned one on top of the other on a United Launch Alliance Atlas V 421 rocket, launched from Cape Canaveral Air Force Station, Florida.
The United Launch Alliance Atlas V rocket with NASA’s Magnetospheric Multiscale (MMS) spacecraft onboard launches from the Cape Canaveral Air Force Station Space Launch Complex 41, Thursday, March 12, 2015, Florida. NASA’s MMS mission studies the mystery of how magnetic fields around Earth connect and disconnect, explosively releasing energy via a process known as magnetic reconnection.
