Guggenheim Aeronautical Laboratory
The Guggenheim Aeronautical Laboratory at the California Institute of Technology (GALCIT), was a research institute created in 1926, at first specializing in aeronautics research. In 1930, Hungarian scientist Theodore von Kármán accepted the directorship of the lab and emigrated to the United States. Under his leadership, work on rockets began there in 1936. GALCIT was the first—and from 1936 to 1940 the only—university-based rocket research center. Based on GALCIT's JATO project at the time, the Jet Propulsion Laboratory was established under a contract with the United States Army in November 1943. In 1961 the GALCIT acronym was retained while the name changed to Graduate Aeronautical Laboratories at the California Institute of Technology. In 2006, during the directorship of Ares J. Rosakis, Ares Rosakis, GALCIT was once again renamed, taking on the new name Graduate Aerospace Laboratories of the California Institute of Technology (while continuing to maintain the acronym ...

National Historic Landmark
A National Historic Landmark (NHL) is a building, district, object, site, or structure that is officially recognized by the United States government for its outstanding historical significance. Only some 2,500 (~3%) of over 90,000 places listed on the country's National Register of Historic Places are recognized as National Historic Landmarks. A National Historic Landmark District may include contributing properties that are buildings, structures, sites or objects, and it may include non-contributing properties. Contributing properties may or may not also be separately listed. Creation of the program Prior to 1935, efforts to preserve cultural heritage of national importance were made by piecemeal efforts of the United States Congress. In 1935, Congress passed the Historic Sites Act, which authorized the Interior Secretary authority to formally record and organize historic properties, and to designate properties as having "national historical significance", and gave the Nation ...

Small Solar System Body
A small Solar System body (SSSB) is an object in the Solar System that is neither a planet, a dwarf planet, nor a natural satellite. The term was first defined in 2006 by the International Astronomical Union (IAU) as follows: "All other objects, except satellites, orbiting the Sun shall be referred to collectively as 'Small Solar System Bodies' ". (IAU) This encompasses all s and all s other than those that are |
JPL Small-Body Database
The JPL Small-Body Database (SBDB) is an astronomy database about small Solar System bodies. It is maintained by Jet Propulsion Laboratory (JPL) and NASA and provides data for all known asteroids and several comets, including orbital parameters and diagrams, physical diagrams, close approach details, radar astrometry, discovery circumstances, alternate designations and lists of publications related to the small body. The database is updated daily when new observations are available. In April 2021 the JPL Small-Body Database Browser started using planetary ephemeris ( DE441) and small-body perturber SB441-N16. Most objects such as asteroids get a two-body solution (Sun+object) recomputed twice a year. Comets generally have their two-body orbits computed at a time near the perihelion passage (closest approach to the Sun) as to have the two-body orbit more reasonably accurate for both before and after perihelion. For most asteroids, the epoch used to define an orbit is updated twice a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psyche (spacecraft)
''Psyche'' is a planned orbiter mission to explore the origin of planetary cores by studying the metallic asteroid of the same name. Lindy Elkins-Tanton of Arizona State University is the principal investigator who proposed this mission for NASA's Discovery Program. NASA's Jet Propulsion Laboratory (JPL) will manage the project. 16 Psyche is the heaviest known M-type asteroid, and was once thought to be the exposed iron core of a protoplanet, the remnant of a violent collision with another object that stripped off its mantle and crust. Numerous recent studies have all but ruled that out. Radar observations of the asteroid from Earth indicate an iron–nickel composition. On January 4, 2017, the ''Psyche'' mission was selected for NASA's Discovery #14 mission, and launch was scheduled for no earlier than September 20, 2022. On June 24, 2022, the Psyche launch was postponed until at least 2023. As of October 2022, Psyche is scheduled to launch no earlier than October 10 ...

X-ray Telescope
An X-ray telescope (XRT) is a telescope that is designed to observe remote objects in the X-ray spectrum. In order to get above the Earth's atmosphere, which is opaque to X-rays, X-ray telescopes must be mounted on high altitude rockets, balloons or artificial satellites. The basic elements of the telescope are the optics (focusing or collimating), that collects the radiation entering the telescope, and the detector, on which the radiation is collected and measured. A variety of different designs and technologies have been used for these elements. Many of the existing telescopes on satellites are compounded of multiple copies or variations of a detector-telescope system, whose capabilities add or complement each other and additional fixed or removable elements (filters, spectrometers) that add functionalities to the instrument. Optics The most common methods used in X-ray optics are grazing incidence mirrors and collimated apertures. Focusing mirrors The utilization of X-r ...
