We have Loved the Stars Too Fondly to be Fearful of the Night

As astronomers studied the electromagnetic spectrum, we learned that the Earth's atmosphere blocked radiation at many wavelengths. While this protected life on Earth, telescopic exploration of the universe would have to be carried out above the surface by satellite telescopes. Here are some of the important and ground-breaking telescopes that help to unlock the secrets of the universe.
James Webb Telescope - now on-line
was - Advanced X-ray Astrophysics Facility (AXAF) - From TRW
Solar and Heliospheric Observatory satellite - over 25 years of solar observing
Neil Gehrels Swift ObservatoryUltraviolet/Optical Telescope (UVOT)
Nancy Grace Roman Space Telescope (RGT)
Under development at Goddard Space Flight Center, the Roman telescope was previously known as Wide Field Infrared Survey Telescope (WFIRST). It is scheduled to be launched in 2027. This instrument has a 2.4m-diameter primary mirror and operates in the visible to near infrared regions of the electromagnetic spectrum. RST will study extra-solar planets, the expansion history of the Universe, dark energy.
Xuntian Space Telescope (XST)
Under development at the Changchun Institute of Optics, Fine Mechanics and Physics, Xuntian will orbit near China's Tiangong space station. The Xuntian telescope has a 2-meter primary mirror. It is scheduled to be launched in December 2023.
Telescope for Orbit Locus Interferometric Monitoring of our Astronomical Neighbourhood (TOLIMAN) - Using astrometry to search for life around Alpha Centauri
Spitzer Space Telescope - formerly SIRTF
On January 30, 2020, Spitzer Space Telescope completed its mission.
