The images acquired by the Mariner 9 Mars orbiter, launched in 1971, revealed the first direct evidence of past water in the form of dry river beds, canyons (including the Valles Marineris, a system of canyons over about 4,020 kilometres (2,500 mi) long), evidence of water erosion and deposition, weather fronts, fogs, and more.

The Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) [1] was a technology demonstration on the NASA Mars 2020 rover Perseverance investigating the production of oxygen on Mars. [2] On April 20, 2021, MOXIE produced oxygen from carbon dioxide in the Martian atmosphere by using solid oxide electrolysis .
This means that Mars has lost a volume of water 6.5 times what is stored in today's polar caps. The water for a time would have formed an ocean in the low-lying Mare Boreum. The amount of water could have covered the planet about 140 meters, but was probably in an ocean that in places would be almost 1 mile deep. [1] [2]
Martian weather cannot be predicted unless dust behavior is studied and understood in the weather context. [ 3 ] [ 8 ] MEDA is a suite of environmental sensors designed to record dust optical properties and six atmospheric parameters: wind speed / direction , pressure , relative humidity , air temperature , ground temperature, and radiation (UV ...
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 ...
NASA will test a nuclear-powered rocket for space travel. The technology could speed up a manned trip to Mars from the current seven-month minimum to 45 days.
By 2008, Mars Odyssey had mapped the basic distribution of water below the shallow surface. [40] The ground truth for its measurements came on July 31, 2008, when NASA announced that the Phoenix lander confirmed the presence of water on Mars, [41] as predicted in 2002 based on data from the Odyssey orbiter. The science team is trying to ...
The study suggests leveraging Rocket Lab’s vertically integrated technologies to retrieve samples from the Red Planet for the first time as part of NASA’s Mars Sample Return Program.
