The Small Explorer program (SMEX) is an effort within NASA to fund space exploration missions that cost no more than {{US$|120 million}}.[1] Extending the larger Explorers program, it was started in 1989.[2] Program historyThe first set of three SMEX missions were launched between 1992 and 1998. The second set of two missions were launched in 1998 and 1999. These missions were managed by the Small Explorer Project Office at NASA's Goddard Space Flight Center (GSFC). In early 1999, that office was closed and with the announcement of opportunity for the third set of SMEX missions NASA converted the program so that each mission was managed by its Principal Investigator, with oversight by the GSFC Explorers Project.[3] As of 2017, NASA is funding a competitive study of five candidate heliophysics Small Explorers missions, with the expectation that one finalist proposal will be selected as a mission for flight in 2022. The proposals are Mechanisms of Energetic Mass Ejection – eXplorer (MEME-X), Focusing Optics X-ray Solar Imager (FOXSI), Multi-Slit Solar Explorer (MUSE), Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS), and Polarimeter to Unify the Corona and Heliosphere (PUNCH).[4][5][6] List of missions
