Following a successful launch at 8:44 p.m. MDT 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 in Florida. After reaching orbit, each spacecraft deployed from the rocket’s upper stage sequentially, in five-minute increments, beginning at 10:16 p.m., with the last separation occurring at 10:32 p.m. NASA scientists and engineers were able to confirm the health of all separated spacecraft at 10:40 p.m.
Comprised of four identical, octagonal spacecraft flying in a pyramid formation, the MMS mission is designed to better understand the physical processes of geomagnetic storms, solar flares, and other energetic phenomena throughout the universe.
LASP will serve as the Science Operations Center for a NASA mission launching this month to better understand the physical processes of geomagnetic storms, solar flares and other energetic phenomena throughout the universe.
The $1.1 billion Magnetospheric Multiscale (MMS) mission will be comprised of four identical, octagonal spacecraft flying in a pyramid formation, each carrying 25 instruments. The goal is to study in detail magnetic reconnection, the primary process by which energy is transferred from the solar wind to Earth’s protective magnetic space environment known as the magnetosphere, said LASP Director Daniel Baker, Science Operations Center (SOC) lead scientist for MMS.
Final preparations are underway for the launch of NASA’s quartet of Magnetospheric Multiscale (MMS) spacecraft, which constitute the first space mission dedicated to the study of magnetic reconnection. This fundamental process occurs throughout the universe where magnetic fields connect and disconnect with an explosive release of energy.
The launch of MMS, on a United Launch Alliance Atlas V rocket, is scheduled for 8:44 p.m. MDT on Thursday, March 12 from Cape Canaveral Air Force Station, Florida.
