MAVEN maps electric currents around Mars, crucial clues to atmospheric loss

NASA's MAVEN spacecraft has created a map of electric currents around Mars, five years after it entered into its orbit. These currents hold crucial clues in the atmospheric loss that made the red planet incapable of supporting life. "These currents play a...

Comet Siding Spring plunged the magnetic field around Mars into chaos

When comet C/2013 A1 (Siding Spring) made its historic encounter with planet Mars in October 2014, passing roughly 140 000 km (87 00 miles) from its surface, it wreaked havoc on the magnetic environment around Mars. The effect, temporary but profound, was measured...

MAVEN data reveals solar wind emptied Mars' atmosphere, left behind a dry planet

Data from NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission has allowed researchers to understand the drastic transformation in the Martian environment - from a wet, warm climate which may have supported life to the cold and dry planet that it has...

MAVEN identifies links in chain leading to atmospheric loss

Early discoveries by NASA’s newest Mars orbiter are starting to reveal key features about the loss of the planet’s atmosphere to space over time. The findings are among the first returns from NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) missio

Siding Spring's flyby effects on Martian atmosphere revealed

Two NASA and one European spacecraft that obtained the first up-close observations of a comet flyby of Mars on October 19, 2014 have gathered new information about the basic properties of the comet’s nucleus and directly detected the effects on the Martian atmosph

Space fleet ready for Siding Spring's historic brush with Mars

C/2013 A1 (Siding Spring) is scheduled for a very close flyby at only about 139 500 km (88 000 miles) away from the surface of Mars on October 19, 2014 around 18:27 UTC. That is less than half the distance between Earth and its moon and less than one-tenth the distance

The evolution of Mars - MAVEN ready for launch

Billions of years ago when the Red Planet was young, it appears to have had a thick atmosphere that was warm enough to support oceans of liquid water - a critical ingredient for life. The animation shows how the surface of Mars might have appeared during this

Mars atmosphere loss: neutral processes

When you take a look at Mars, you probably wouldn't think that it looks like a nice place to live. It's dry, it's dusty, and there's practically no atmosphere. But some scientists think that Mars may have once looked like a much nicer place to live,

MAVEN gets magnetometers to study the Red planet's magnetic field

Could Mars have supported life? Many scientists think that long ago it had a denser atmosphere, cloudy skies that supported liquid water flowing over the surface. They propose the red planet lost its atmosphere due to sputtering as it eroded by
