List Of Proposed Space Observatories
This list contains proposals for space telescopes, space-based (situated in space) astronomical observatories. It is a list of past and present space observatory plans, concepts, and proposals. For observatories in orbit, see list of space telescopes. Unlike that list, this one includes concepts and proposals that are unlikely ever to be launched, as they may have been cancelled or were only proposals. Space observatories under development Merged, cancelled, or superseded space observatories Additional examples and non-space telescopes For launch in the 2030s, NASA is evaluating four possible designs: the Origins Space Telescope, Lynx X-ray Observatory, Habitable Exoplanets Observatory (HabEx), and Large UV Optical Infrared Surveyor (Large Ultraviolet Optical Infrared Surveyor, LUVOIR). Balloon-borne telescopes have been in use since the 1950s. A 20–30 meter balloon telescope has been suggested. The balloon would be transparent on one side, and have a circular re ...

Space Telescopes
A space telescope (also known as space observatory) is a telescope in outer space used to observe astronomical objects. Suggested by Lyman Spitzer in 1946, the first operational telescopes were the American Orbiting Astronomical Observatory, OAO-2 launched in 1968, and the Soviet Orion 1 ultraviolet telescope aboard space station Salyut 1 in 1971. Space telescopes avoid several problems caused by the atmosphere, including the absorption or scattering of certain wavelengths of light, obstruction by clouds, and distortions due to atmospheric refraction such as twinkling. Space telescopes can also observe dim objects during the daytime, and they avoid light pollution which ground-based observatories encounter. They are divided into two types: Satellites which map the entire sky (astronomical survey), and satellites which focus on selected astronomical objects or parts of the sky and beyond. Space telescopes are distinct from Earth imaging satellites, which point toward Earth f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compton Spectrometer And Imager
The Compton Spectrometer and Imager (COSI) is a NASA Explorers Program, SMEX astrophysics mission that will launch a soft Gamma-ray astronomy, gamma-ray telescope (0.2–5 MeV) in 2027. It is a wide-field compact Compton telescope (CCT) that is uniquely suited to investigate the "MeV gap" (0.1–10 MeV). It provides imaging, spectroscopy, and polarimetry of astrophysical sources, and its germanium detectors provide excellent energy resolution for emission line measurements. The germanium detectors have an instantaneous field of view of more than 25% of the sky, and they are surrounded on the sides and bottom by active shields, which provide background rejection while also allowing for detection of gamma-ray bursts and other gamma-ray flares across the majority of the sky. History COSI has its origins in the Nuclear Compton Telescope (NCT), which was a prototype designed to study astrophysical sources of nuclear line emission and gamma-ray polarization. The NCT was a balloo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taiji Program In Space
The Taiji program is a proposed Chinese satellite-based gravitational-wave observatory. It is scheduled for launch in 2033 to study ripples in spacetime caused by gravitational waves. The program consists of a triangle of three spacecraft orbiting the Sun linked by laser interferometers. There are two alternative plans for Taiji. One is to take a 20 percent share of the European Space Agency's LISA project; the other is to launch China's own satellites by 2033 to authenticate the ASE project. Like LISA, the Taiji spacecraft would be 3 million kilometers apart, making them sensitive to as similar range of frequencies, although Taiji is proposed to perform better in some of that range. Program Goal 'Taiji Program' is the ELISA Program proposed by ESA, and the predecessor of the ELISA Program is the LISA Program cooperated by ESA and NASA. Similar to the configuration of the three networking satellites in the LISA Program, the three satellites in the Taiji Program also rotate a ...

Advanced X-Ray Imaging Satellite
Advanced X-ray Imaging Satellite (AXIS) is a space telescope under development by NASA for launch in 2032. It is a NASA Probe mission concept designed for high angular resolution X-Ray imaging. The mission goals are to examine galaxies over cosmic time, feedback in galaxies, Black Hole strong gravity, Dual AGN, the high redshift universe. History The Advanced X-ray Imaging Satellite (AXIS), a response to NASA's Astrophysics Probe Explorer (APEX) program. Instruments The X-ray grazing incident mirror would be developed by NASA Goddard Space Flight Center and combines 10,000 mirror segments made from silicon, grouped into 10 shells. The detector is an array of CCDs giving a field of view of about 24 arcminutes and a spatial resolution of about 1.5 arcsecond over the entire field. See also * List of proposed space observatories * International X-ray Observatory The International X-ray Observatory (IXO) is a cancelled X-ray telescope that was to be launched in 2021 as a joint ...

Grenoble Alpes University
The (, ''Grenoble Alps University'', abbr. UGA) is a ''grand établissement'' in Grenoble, France. Founded in 1339, it is the third largest university in France with about 60,000 students and over 3,000 researchers. Established as the University of Grenoble by Humbert II of Viennois, it split in 1970 following the widespread civil unrest of May 1968. Three of the University of Grenoble's successors—Joseph Fourier University, Pierre Mendès-France University, and Stendhal University—merged in 2016 to restore the original institution under the name . In 2020, the Grenoble Institute of Technology, the Grenoble Institute of Political Studies, and the Grenoble School of Architecture also merged with the original university. The university is organized around two closely located urban campuses: Domaine Universitaire, which straddles Saint-Martin-d'Hères and Gières, and Campus GIANT in Grenoble. UGA also owns and operates facilities in Valence, Chambéry, Les Houches, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extremely High Frequency
Extremely high frequency (EHF) is the International Telecommunication Union designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz). It is in the microwave part of the radio spectrum, between the super high frequency band and the terahertz band. Radio waves in this band have wavelengths from ten to one millimeter, so it is also called the millimeter band and radiation in this band is called millimeter waves, sometimes abbreviated MMW or mmWave. Some define mmWaves as starting at 24 GHz, thus covering the entire FR2 band (24.25 to 71 GHz), among others. Compared to lower bands, radio waves in this band have high atmospheric attenuation: they are absorbed by the gases in the atmosphere. Absorption increases with frequency until at the top end of the band the waves are attenuated to zero within a few meters. Absorption by humidity in the atmosphere is significant except in desert environments, and attenuation by rain ( rain f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JAXA
The is the Japanese national air and space agency. Through the merger of three previously independent organizations, JAXA was formed on 1 October 2003. JAXA is responsible for research, technology development and launch of satellites into orbit, and is involved in many more advanced missions such as asteroid exploration and possible human exploration of the Moon. Its motto is ''One JAXA'' and its corporate slogan is ''Explore to Realize'' (formerly ''Reaching for the skies, exploring space''). History On 1 October 2003, three organizations were merged to form the new JAXA: Japan's Institute of Space and Astronautical Science (ISAS), the National Aerospace Laboratory of Japan (NAL), and National Space Development Agency of Japan (NASDA). JAXA was formed as an Independent Administrative Institution administered by the Ministry of Education, Culture, Sports, Science and Technology (MEXT) and the Ministry of Internal Affairs and Communications (MIC).
