In the summer of 2008, the TEGA and WCL experiments on the 2007 Phoenix Mars lander found between 3–5wt% (percent by weight) calcite (CaCO 3) and an alkaline soil. [65] In 2010, analyses by the Mars Exploration Rover Spirit identified outcrops rich in magnesium-iron carbonate (16–34 wt%) in the Columbia Hills of Gusev crater. The magnesium ...
A mineral grain from a meteorite preserved evidence that water was present on Mars 4.45 billion years ago, and it may have created hot springs habitable for life. ‘Black Beauty’ was found on ...
Martian regolith is toxic, due to relatively high concentrations of perchlorate compounds containing chlorine. [3] Elemental chlorine was first discovered during localised investigations by Mars rover Sojourner, and has been confirmed by Spirit, Opportunity and Curiosity.
Deep Impact at Comet 9P/Tempel 1 Dart Impact at Dimorphos Mars 2020 Skycrane descend stage crash smoke plume in the distance. This is a list of uncrewed spacecraft which have been intentionally destroyed at their objects of study, typically by hard landings or crash landings at the end of their respective missions and/or functionality.
The Mars Global Surveyor, active from 1997 to 2006, was the first spacecraft able to image Mars in high enough resolution to detect new impacts, with a resolution of up to 1.5 meters (4.9 ft). The first detected impact, a 14.4-meter (47 ft)-diameter crater in southern Lucus Planum , happened between 27 January 2000, and 19 March 2001. [ 2 ]
Microscopic images of the soil taken by Opportunity revealed small spherically shaped granules. They were first seen on pictures taken on Sol 10, right after the rover drove from the lander onto martian soil. When Opportunity dug her first trench (Sol 23), pictures of the lower layers showed similar round spherules. But this time they had a ...
Launched in 1996, it used the Mars Orbiter Camera (MOC), Mars Orbital Laser Altimeter, and Thermal Emission Spectrometer to show layering on the surface, presence of surface ice, and the mineral hematite. The presence of ice over the surface is essential to understanding why certain water bearing minerals are on Mars.
Among those killed were two people in the eastern state of Saxony, according to local public broadcaster MDR, including a 45-year-old man who was killed after handling what was described as a ...
