讲座摘要：
NASA’s magnetospheric multiscale (MMS) mission aims to discover the electron-scale physics of magnetic reconnection, which is a dominant mechanism for eruptive processes in space plasma environment. The mission was launch on March 12th, 2015 UT, and contains four identical spacecraft forming a tetrahedron with about 10 km separation. More than 60 MMS articles were published in Science, PRL, GRL, and JGR until now. This talk will introduce the mission, instruments, and the on-going sciences briefly. Two topics that I was working on will be presented in detail. The first one is the kinetic physics due to Kelvin-Helmholtz instability; the other one is the cold ions in magnetic reconnection. The high-resolution observations of MMS provide the first opportunity to study these problems.
