Centaurus (spacecraft Mission)
''Centaurus'' is a mission concept to flyby the centaurs 2060 Chiron and Schwassmann–Wachmann 1. It was submitted in response to the NASA Discovery program call for proposals in 2019 but ultimately was not among the four missions selected for further development by NASA in February 2020. If it had been selected, ''Centaurus'' would have been the first mission to attempt a flyby of a centaur. Overview If selected, ''Centaurus'' would have been capable of launching in any year between 2026 and 2029. The primary targets of the ''Centaurus'' mission were the centaurs 2060 Chiron and 29P/Schwassmann–Wachmann (often shortened to "SW1"). Centaurs are "escapees" from the Kuiper belt with giant planet-crossing orbits. Both objects are active centaurs with perihelia within the orbit of Saturn. The ''Centaurus'' payload included imagers and spectrometers to study the surfaces, comae, and any potential rings and shepherd moons around these objects. Use of solar panels would have ...

Flyby (spaceflight)
A flyby () is a spaceflight operation in which a spacecraft passes in proximity to another body, usually a target of its space exploration mission and/or a source of a gravity assist to impel it towards another target. Spacecraft which are specifically designed for this purpose are known as flyby spacecraft, although the term has also been used in regard to asteroid flybys of Earth for example. Important parameters are the time and distance of closest approach. Spacecraft flyby Flyby maneuvers can be conducted with a planet, a natural satellite or a non-planetary object such as a small Solar System body. Planetary flybys have occurred with Mars or Earth for example: *List of Earth flybys * Mars flyby An example of a comet flyby is when International Cometary Explorer (formerly ISEE-3) passed about from the nucleus of Comet Giacobini-Zinner in September 1985. Another application of the flyby is of Earth's Moon, usually called a lunar flyby. The Apollo 13 spacecraft had an exp ...

10199 Chariklo
10199 Chariklo is the largest confirmed centaur (small body of the outer Solar System). It orbits the Sun between Saturn and Uranus, grazing the orbit of Uranus. On 26 March 2014, astronomers announced the discovery of two rings (nicknamed as the rivers Oiapoque and Chuí) around Chariklo by observing a stellar occultation, making it the first minor planet known to have rings. A photometric study in 2001 was unable to find a definite period of rotation. Infrared observations of Chariklo indicate the presence of water ice, which may in fact be located in its rings. Michael Brown's website lists it as possibly a dwarf planet with a measured diameter of 232 km. Discovery and naming Chariklo was discovered by James V. Scotti of the Spacewatch program on February 15, 1997. Chariklo is named after the nymph Chariclo ('), the wife of Chiron and the daughter of Apollo. A symbol derived from that for 2060 Chiron, x14px, was devised in the late 1990s by German astro ...

List Of Solar System Probes
This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions. Flybys (such as gravity assists) that were incidental to the main purpose of the mission are also included. Flybys of Earth are listed separately at List of Earth flybys. Confirmed future probes are included, but missions that are still at the concept stage, or which never progressed beyond the concept stage, are not. Key Colour key: * † means "tentatively identified", as classified by NASA. These are Cold War-era Soviet missions, mostly failures, about which few or no details have been officially released. The information given may be speculative. * Date is the date of: :* closest encounter (flybys) :* impact (impactors) :* orbital inserti ...

List Of Missions To Minor Planets
List of missions to minor planets is a listing of spaceflight missions to minor planets, which are category of astronomical body that excludes planets, moons and comets, but orbit the Sun. Most missions to minor planets have been to asteroids or dwarf planets. Spacecraft visits to minor planets have mostly been flybys, and have ranged from dedicated missions to incidental flybys and targets of opportunity for spacecraft that have already completed their missions. The first spacecraft to visit an asteroid was Pioneer 10, which flew past an unnamed asteroid on 2 August 1972; a distant incidental encounter while the probe was en route to Jupiter. The first dedicated mission was ''NEAR Shoemaker'', which was launched in February 1996, and entered orbit around 433 Eros in February 2000, having first flown past 253 Mathilde. ''NEAR'' was also the first spacecraft to land on an asteroid, surviving what was intended to be an impact with Eros at 20:01 on 12 February 2001 at the planned end ...

Principal Investigator
In many countries, the term principal investigator (PI) refers to the holder of an independent grant and the lead researcher for the grant project, usually in the sciences, such as a laboratory study or a clinical trial. The phrase is also often used as a synonym for "head of the laboratory" or "research group leader". While the expression is common in the sciences, it is used widely for the person or persons who make final decisions and supervise funding and expenditures on a given research project. A co-investigator (Co-I) assists the principal investigator in the management and leadership of the research project. There may be a number of co-investigators supporting a PI. Federal funding In the context of United States federal funding from agencies such as the National Institutes of Health (NIH) or the National Science Foundation (NSF), the PI is the person who takes direct responsibility for completion of a funded project, directing the research and reporting directly to the fun ...
