NASA's Solar Terrestrial Probes program (STP) is a series of missions focused on studying the Sun-Earth system. It is part of NASA's Heliophysics Science Division within the Science Mission Directorate.[1]
The TIMED (Thermosphere Ionosphere Mesosphere Energetics and Dynamics) is an orbiter mission dedicated to study the dynamics of the Mesosphere and Lower Thermosphere (MLT) portion of the Earth's atmosphere.[2] The mission was launched from Vandenberg Air Force BaseinCalifornia on December 7, 2001 aboard a Delta II rocket launch vehicle.[3]
Hinode, an ongoing collaboration with JAXA, is a mission to explore the magnetic fields of the Sun.[4] It was launched on the final flight of the M-V-7 rocket from Uchinoura Space Center, Japan on September 22, 2006.
STEREO (Solar Terrestrial Relations Observatory) is a solar observation mission.[5] It consists in two nearly identical spacecraft, launched on October 26, 2006.
The Magnetospheric Multiscale Mission (MMS) is a mission to study the Earth's magnetosphere, using four identical spacecraft flying in a tetrahedral formation.[6] The spacecraft were launched on March 13, 2015.
IMAP (Interstellar Mapping and Acceleration Probe) is a heliosphere observation mission. Planned for launch in 2025, it will sample, analyze, and map particles streaming to Earth from the edges of interstellar space.[7]
