The imaging and spectroscopic results from the Spitzer Space Telescope will create a solid foundation for future observatories to build upon. Space telescopes such as the Hubble Space Telescope and the Spitzer Space Telescope have allowed us to capture views of galaxies and nebulas far away from our own solar system. Thanks to its ability to detect radiation at far infrared and sub-millimetre wavelengths, Herschel will be able to observe dust obscured and cold objects that are invisible to other telescopes. About the Spitzer Space Telescope What is the Spitzer Space Telescope? Unlike the Hubble Space Telescope, which orbits Earth, Kepler has been placed in what's called an "Earth trailing" orbit around the sun. The Herschel Space Observatory's mission has been designed to unveil a face of the early Universe that has remained hidden until now. The Herschel Space Observatory With the Herschel Space Observatory believed to have entered its final year of operation, we take a look back at the telescope’s short life. An artist's depiction of the long-lived Kepler space telescope and some of the planets it discovered during its near-decade in space. A little wider and slower than our own orbit, the spacecraft will take 371 days to complete one circuit. ... Spitzer is the largest infrared telescope ever put into space. Herschel observed the far-infrared sky from 2009 to 2013, and while Spitzer is still operating, it’s observing in a … Spitzer Space Telescope, U.S. satellite, the fourth and last of the NASA fleet of ‘Great Observatories.’ Studying the cosmos in infrared light, it discovered three planets in the habitable zone of the TRAPPIST-1 system and the outermost ring of Saturn. The telescope was several decades in the making. The European Space Agency’s Herschel Space Observatory was launched in May 2009 and is currently expected to remain operational for around another year. The entire Observatory has a mass of about 935 kilograms, or about 2000 pounds. 2. Hubble’s early origins date back as far as 1946—more than 10 years before NASA was established. NASA’s Spitzer Space Telescope and the European Space Agency’s Herschel Space Observatory were the last to probe this long-wavelength regime.

On April 24, 1990, the Hubble Space Telescope rocketed into low-Earth orbit, where it's remained for 30 years.
