Galaxy Evolution Explorer
Galaxy Evolution Explorer (GALEX or Explorer 83 or SMEX-7) was a NASA orbiting space telescope designed to observe the universe in ultraviolet wavelengths to measure the history of star formation in the universe. In addition to paving the way for future ultraviolet missions, the space telescope allowed astronomers to uncover mysteries about the early universe and how it evolved, as well as better characterize phenomena like black holes and dark matter. GALEX was launched on 28 April 2003 for a 29-month primary mission, which was extended three times before the spacecraft was placed into standb

Nuclear Spectroscopic Telescope Array
NuSTAR (Nuclear Spectroscopic Telescope Array, also named Explorer 93 and SMEX-11) is a NASA space-based X-ray telescope that uses a conical approximation to a Wolter telescope to focus high energy X-rays from astrophysical sources, especially for nuclear spectroscopy, and operates in the range of 3 to 79 keV.

Transition Region And Coronal Explorer
Transition Region and Coronal Explorer (TRACE, or Explorer 73, SMEX-4) was a NASA heliophysics and solar observatory designed to investigate the connections between fine-scale magnetic fields and the associated plasma structures on the Sun by providing high-resolution images and observation of the solar photosphere, the transition region, and the solar corona. A main focus of the TRACE instrument was the fine structure of coronal loops low in the solar atmosphere. TRACE was the third spacecraft in the Small Explorer program, launched on 2 April 1998, and obtained its last science image on 21 J

SCISAT-1
SCISAT-1 is a Canadian satellite designed to make observations of the Earth's atmosphere. Its main instruments are an optical Fourier transform infrared spectrometer, the ACE-FTS Instrument, and an ultraviolet spectrophotometer, MAESTRO. These devices record spectra of the Sun, as sunlight passes through the Earth's atmosphere, making analyses of the chemical elements of the atmosphere possible.

The Fast On-orbit Rapid Recording of Transient Events (FORTE, occasionally stylized as FORTÉ; COSPAR 1997-047A, SATCAT 24920) is a lightweight satellite which was launched at about 8:30 AM on August 29, 1997 into a circular low Earth orbit which is inclined 70 degrees relative to the Earth's equator, using a Pegasus XL rocket. It was developed and launched by the Los Alamos National Laboratory in cooperation with Sandia National Laboratory, as a testbed for technologies applicable to U.S. nuclear detonation detection systems u

C/NOFS, or Communications/Navigation Outage Forecasting System was a USAF satellite developed by the Air Force Research Laboratory (AFRL) Space Vehicles Directorate to investigate and forecast scintillations in the Earth's ionosphere. It was launched by an Orbital Sciences Corporation Pegasus-XL launch vehicle at 17:02:48 UTC on 16 April 2008 and decayed on 28 November 2015.
