Summary
MMS 3, also known as Magnetospheric Multiscale spacecraft 3, is a US satellite developed by GSFC (Goddard Space Flight Center) for magnetospheric research. Launched on March 13, 2015, from Cape Canaveral Air Force Station's SLC41 launch pad using the Atlas V 421 launch vehicle, this satellite has dimensions of 1.2 meters in length and a diameter of 3.6 meters with a span of 112 meters due to its antennae. It weighs 1000 kg dry and had an initial mass of 1360 kg at launch. MMS 3 is equipped with solar cells and batteries for power, has a shape described as cylindrical with antennae, and a surface area of approximately 2.6555 square meters. The satellite's mission was expected to last around 2.5 years, focusing on magnetospheric research within the Magnetospheric Multiscale constellation managed by GSFC.
