In February 2013, NASA published the most detailed and accurate 3D map of Mercury to date, assembled from thousands of images taken by MESSENGER. [21] The probe continued collecting scientific data until April 30, 2015, when under a decaying orbit, the probe was allowed to crash onto the surface of Mercury.
It was created by NASA physician William Randolph Lovelace, who developed the physical and psychological tests used to select NASA's first seven male astronauts for Project Mercury. The women completed physical and psychological tests, but were never required to complete the training as the privately funded program was quickly cancelled.
Mercury is one of four terrestrial planets in the Solar System, which means it is a rocky body like Earth. It is the smallest planet in the Solar System, with an equatorial radius of 2,439.7 kilometres (1,516.0 mi). [4] Mercury is also smaller—albeit more massive—than the largest natural satellites in the Solar System, Ganymede and Titan.
The Mercury-Redstone Launch Vehicle, designed for NASA's Project Mercury, was the first American crewed space booster.It was used for six sub-orbital Mercury flights from 1960–1961; culminating with the launch of the first, and 11 weeks later, the second American (and the second and third humans) in space.

The Mercury Space Flight Network (MSFN) was completed in 1961, ... Carnarvon NASA tracking station, circa 1969 Ascension tracking station in 2005.
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.
Mercury could have a thick underground layer of diamonds, scientists say. Some of the stones may have found their way to the surface, according to a recent study. Mercury could have an 11-mile ...
