Prior to launch, there was a proposal call for large, coherent investigations using Spitzer. The first released images from Spitzer were designed to show off the abilities of the telescope and showed a glowing stellar nursery, a big swirling, dusty galaxy, a disc of planet-forming debris, and organic material in the distant universe. Mit kreativen Lösungen wurde „Spitzer“ immer weiter am Leben gehalten, mehrmals wurde die Mission des Weltraumteleskops verlängert - immer mit Blick in die Zukunft: Das geplante Weltraumteleskop „James Web Space Telescope“ soll neue Bilder aus dem frühen Universum liefern.

Zu den vier Weltraumteleskopen* zählen auch „Hubble“, das Röntgenteleskop „Chandra“ und das Gammastrahlen-Observatorium „Compton Gamma Ray Observatory“. [58] Spitzer used the transit photometry and gravitational microlensing techniques to perform these observations. „,Spitzer‘ ist weiter von der Erde entfernt, als wir je dachten, dass es sein würde, während es noch in Betrieb ist“, sagte Nasa-Manager Sean Carey zum 15. Astronomers have used a technique nicknamed "echo mapping" to measure the luminosity of black hole disks in over 500 galaxies. "[12], The US$776 million[15] Spitzer was launched on 25 August 2003 at 05:35:39 UTC from Cape Canaveral SLC-17B aboard a Delta II 7920H rocket.

Unlike most telescopes that are named by a board of scientists, typically after famous deceased astronomers, the new name for SIRTF was obtained from a contest open to the general public. [35] This was the first time the light from extrasolar planets had been directly detected; earlier observations had been indirectly made by drawing conclusions from behaviors of the stars the planets were orbiting. The new images of the comet were taken on 8 August and feature the visitor’s coma, the fine shell that surrounds its nucleus, and its dusty output. [57] According to NASA's Sean Carey, "We never even considered using Spitzer for studying exoplanets when it launched. Scientists have long wondered how tiny silicate crystals, which need high temperatures to form, have found their way into frozen comets, born in the very cold environment of the Solar System's outer edges. However, after the 1986 Challenger disaster, the Centaur LH2–LOX upper stage, which would have been required to place it in its final orbit, was banned from Shuttle use. What is Spitzer Space Telescope?

Das „Spitzer“-Weltraumteleskopwird nach fast 17 Jahren abgeschaltet Das Teleskopkämpfte bereits länger mit … [49], Spitzer observations, announced in May 2011, indicate that tiny forsterite crystals might be falling down like rain on to the protostar HOPS-68. Das Weltraumteleskop „Spitzer“ der Nasa hat fast 17 Jahre durchgehalten. Pre-launch tests had been conducted to determine the expected performance of the equipment in this state, along with tests at the University of Rochester, confirming the continuing capability of the detectors. Doch sein Starttermin im Jahr 2021 scheint derzeit zu wackeln. This orbit also simplifies telescope pointing, but does require the NASA Deep Space Network for communications. Humanity has "eyes" that can detect all different types of light through telescopes around the globe and a fleet of observatories in space. Phillips Davis

Like a prism breaking up light into a rainbow, the spectrograph takes the incoming infrared light from a distant object and breaks it up into a spectrum.

The launch of SIRTF in 2003 aboard the 300th Delta rocket. [12] Spitzer wrote a 1946 report for RAND Corporation describing the advantages of an extraterrestrial observatory and how it could be realized with available or upcoming technology.

Surveying sunspots is the most basic of ways we study how solar activity rises and falls over time, and it’s the basis of how we track the solar cycle.
