MESSENGER was a NASA robotic space probe that orbited the planet Mercury between 2011 and 2015, studying Mercury's chemical composition, geology, and magnetic field. [ 9 ][ 10 ] The name is a backronym for "Mercury Surface, Space Environment, Geochemistry, and Ranging", and a reference to the messenger god Mercury from Roman mythology.
The first probe to visit Mercury was Mariner 10. View of Mercury from Mariner 10 in March 1975. The exploration of Mercury has a minor role in the space interests of the world. It is the least explored inner planet. [1] As of 2015, the Mariner 10 and MESSENGER missions have been the only missions that have made close observations of Mercury.
Messenger, [11] also known as Facebook Messenger, is an American proprietary instant messaging service developed by Meta Platforms.Originally developed as Facebook Chat in 2008, the client application of Messenger is currently available on iOS and Android mobile platforms, Windows and macOS desktop platforms, through the Messenger.com web application, and on the standalone Facebook Portal ...
On NASA's MESSENGER mission, she served as the Instrument Scientist for the Mercury Dual Imaging System (MDIS) and the Chair of the Geology Discipline Group. She was the lead for MDIS-based scientific investigations of Mercury's polar, radar-bright, ice-bearing craters and led the release of web images since MESSENGER's first flyby of Mercury ...
Mariner 10 was an American robotic space probe launched by NASA on 3 November 1973, to fly by the planets Mercury and Venus. It was the first spacecraft to perform flybys of multiple planets. [3] Mariner 10 was launched approximately two years after Mariner 9 and was the last spacecraft in the Mariner program.
Hollows are a landform on the planet Mercury, discovered during the MESSENGER mission that orbited the planet from 2011 to 2015. Hollows are typically clusters of rimless depressions with flat floors and haloes of bright (high albedo) material surrounding them. Hollows are thought to form by loss of volatiles from the surface by sublimation ...
A planetary flyby is the act of sending a space probe past a planet or a dwarf planet close enough to record scientific data. [1] This is a subset of the overall concept of a flyby in spaceflight. The first flyby of another planet with a functioning spacecraft took place on December 14, 1962, when Mariner 2 zoomed by the planet Venus.
ʻOumuamua is a small object estimated to be between 100 and 1,000 metres (300 and 3,000 ft) long, with its width and thickness both estimated between 35 and 167 metres (115 and 548 ft). [ 13 ] It has a red color, like objects in the outer Solar System.
