The small STEDI (Student Explorer Demonstration Initiative) program was also known as the University Explorer (UNEX) series. First launch was the HETE astronomy satellite built by the Massachusetts Institute of Technology. This was followed by SNOE, the Student Nitric Oxide Explorer, built by the University of Colorado. Major Events: .
The High Energy Transient Experiment (HETE) is an international mission led by The Massachusetts Institute of Technology (MIT). Its prime objective is to carry out the first multiwavelength study of gamma ray bursts (GRBs) with UV, X-ray, and gamma ray instruments. A unique feature of the mission is its capability to localise bursts with several arcsecond accuracy, in near real-time aboard the spacecraft. These positions are transmitted to the ground, and picked up by a global network of primary and secondary ground stations (SGS), enabling sensitive follow-up studies.
SNOE, the Student Nitric Oxide Explorer. Small satellite built by the University of Colorado to measure the Nitric Oxide density as a function of altitude. First satellite in the STEDI (Student Explorer Demonstration Initiative) program.
