Wide-field Infrared Survey Explorer (WISE, observatory code C51, Explorer 92 and MIDEX-6) was a NASA infrared astronomy space telescope in the Explorers Program launched in December 2009. [ 2 ] [ 3 ] [ 4 ] WISE discovered thousands of minor planets and numerous star clusters .
Neil Gehrels Swift Observatory, previously called the Swift Gamma-Ray Burst Explorer, is a NASA three-telescope space observatory for studying gamma-ray bursts (GRBs) and monitoring the afterglow in X-ray, and UV/visible light at the location of a burst. [5] It was launched on 20 November 2004, aboard a Delta II launch vehicle. [4]
An Explorer mission observes Sagittarius A*, the Milky Way's central black hole, flaring. The Explorers program [1] is a NASA exploration program that provides flight opportunities for physics, geophysics, heliophysics, and astrophysics investigations from space. Launched in 1958, Explorer 1 was the first spacecraft of the United States to ...
Wide-field Infrared Explorer (WIRE, also Explorer 75 and SMEX-5) was a NASA satellite launched on 5 March 1999, on the Pegasus XL launch vehicle into polar orbit between 409 and 426 km (254 and 265 mi) above the surface of Earth.
SPHEREx will use a spectrophotometer to perform an all-sky survey that will measure near-infrared spectra from 0.75 to 5.0 micrometers. It will employ a single instrument with a single observing mode and no moving parts to map the entire sky (in 96 different color bands, far exceeding the color resolution of previous all-sky maps [4]) four times during its nominal 25-month mission; the crucial ...
Imaging X-ray Polarimetry Explorer, commonly known as IXPE or SMEX-14, is a space observatory with three identical telescopes designed to measure the polarization of cosmic X-rays of black holes, neutron stars, and pulsars. [6]
