NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission has identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm and wet environment that might have ...
ESA's Mars Express has shed new light on the Red Planet's rare ultraviolet aurora by combining for the first time remote observations with in situ measurements of electrons hitting the atmosphere.
Scientists may be closer to solving the mystery of how Mars changed from a world with surface water billions of years ago to the arid Red Planet of today.
If planets had personalities, Mars would be a rock star according to recent preliminary results from NASA's MAVEN spacecraft. Mars sports a "Mohawk" of escaping atmospheric particles at its poles, "wears" a layer of metal ...
An international team of researchers has discovered traces of methane in Martian meteorites, a possible clue in the search for life on the Red Planet.
In June 2015, Mars will swing almost directly behind the sun from Earth's perspective, and this celestial geometry will lead to diminished communications with spacecraft at Mars.
Mars. It's a pretty unforgiving place. On this dry, dessicated world, the average surface temperature is -55 °C (-67 °F). And at the poles, temperatures can reach as low as -153 °C (243 °F). Much of that has to do with ...
An international team of researchers has for the first time predicted the occurrence of aurorae visible to the naked eye on a planet other than Earth.
The United Arab Emirates' planned 2020 mission to Mars will study the planet's atmosphere and be appropriately named "Hope," members of the project team revealed Wednesday.
NASA has beefed up a process of traffic monitoring, communication and maneuver planning to ensure that Mars orbiters do not approach each other too closely.
