The Explorers and Heliophysics Projects Division (EHPD) consists of three programs: Explorers, Living With a Star (LWS), and Solar Terrestrial Probes (STP). The Explorers Program is an uncoupled Program which provides frequent flight opportunities for world-class scientific investigations from space within NASA Heliophysics and Astrophysics Space Science goals. Explorers projects are typically implemented in the Principal Investigator (PI) mode. The LWS Program is a loosely coupled Program which provides missions to improve our understanding of how and why the Sun varies, how the Earth and Solar System respond, and how the variability and response affects humanity in Space and on Earth. The STP Program is an uncoupled Program which provides missions to understand the fundamental physics processes from the Sun to Earth, to outer planets, and beyond to the interstellar medium.
03.11.15 – Scheduled to lift off on March 12, 2015, NASA's new Magnetospheric Multiscale, or MMS, mission consists of four identical spacecraft that each carry 25 sensors with unprecedented observational speeds. All that power will be essential to gather the first ever, three-dimensional measurements of a little understood phenomena in space called magnetic reconnection. Magnetic reconnection happens when magnetic field lines realign quickly and explosively, initiating the movement of large-scale flows of particles, and accelerating particles up to nearly the speed of light. This is one of the most dramatic occurrences in space, powering gigantic explosions on our closest star such as solar flares, and causing particles to funnel into near-Earth space leading to aurora.
