Prognoz 6 carried two NaI(Tl) scintillators (2-511 keV, 2.2-98 keV), and a proportional counter (2.2-7 keV) to study solar X-rays. The Space Test Program spacecraft P78-1 or Solwind was launched on February 24, 1979 and continued operating until September 13, 1985, when it was shot down in orbit during an Air Force ASM-135 ASAT test. The ...
This is a timeline of space exploration which includes notable achievements, first accomplishments and milestones in humanity's exploration of outer space. This timeline generally does not distinguish achievements by a specific country or private company, as it considers humanity as a whole.
The X-ray colors represent the temperature of the X-ray emission from each star: hot stars are blue-white and cooler stars are yellow-red. The brightest object in the optical image is the full moon, which is also in the X-ray image. The X-ray image was actually obtained by the ROSAT satellite during the All-Sky Survey phase in 1990–1991.
For a satellite or space probe to qualify as a deep space X-ray astronomer/explorer or "astronobot"/explorer, all it needs to carry aboard is an XRT or X-ray detector and leave Earth's orbit. Ulysses was launched October 6, 1990, and reached Jupiter for its " gravitational slingshot " in February 1992.
The Uhuru satellite, designed to map the sky at X-ray wavelengths, is launched by NASA. The existence of X-rays from the Sun and a few other stars has already been found using rocket-launched experiments, but Uhuru charts more than 300 X-ray sources, including several possible black holes.
Four Great Observatories. NASA's series of Great Observatories satellites are four large, powerful space-based astronomical telescopes launched between 1990 and 2003. They were built with different technology to examine specific wavelength/energy regions of the electromagnetic spectrum: gamma rays, X-rays, visible and ultraviolet light, and infrared light.
2021 — James Webb Space Telescope (JWST), was launched 25 December 2021 on an ESA Ariane 5 rocket from Kourou, French Guiana and will succeed the Hubble Space Telescope as NASA's flagship mission in astrophysics. 2023 — Euclid, was launched on 1 July 2023 on a Falcon 9 Block 5 rocket from Cape Canaveral, Florida, to study dark matter and ...
Chandra X-ray Observatory, launched July 1999, operational; Spitzer Space Telescope, launched August 2003, completed; High Energy Astronomy Observatory program; High Energy Astronomy Observatory 1 (HEAO 1), launched August 1977, completed; Einstein Observatory (HEAO 2) launched November 1978, completed – first fully imaging X-ray telescope
