NASA's study reveals some Martian auroras form via a process similar to Earth's Dungey cycle, involving magnetic reconnection ...

Today, Mars is a cold, dry planet covered in dust, but scientists believe it looked very different billions of years ago, ...

Mars may react differently when trouble arrives from two directions at once. A solar particle storm and a planet-wide dust storm overlapped in 2018, and temperatures rose in the lower atmosphere ...

NASA MAVEN (Mars Atmosphere and Volatile Evolution) mission scientists have uncovered a key puzzle piece in understanding certain types of auroras on Mars, finding that they form in a similar way to ...

(NEW YORK) — Mars is a cold, dry, desert-like planet. But billions of years ago, scientific evidence suggests that it had a thick atmosphere, which kept it warm enough to support flowing water on its ...

Over more than a decade at Mars, the orbiter revealed how the solar wind strips away the planet’s atmosphere — and why the world lost its water.

Envision a time when hundreds of spacecraft are exploring the solar system and beyond. That’s the future that NASA’s ESCAPADE, or Escape and Plasma Acceleration and Dynamics Explorers, mission will ...

We know Mars to be many things: dusty, cold, and missing a global magnetic field. In a recent discovery that baffled scientists, a space weather phenomenon previously associated with powerful magnetic ...

After six months of radio silence, NASA’s Maven spacecraft at Mars has been declared dead. The space agency confirmed Wednesday that the mission had ended after more than a decade of observations.

NASA MAVEN has officially reached the end of its active mission after more than a decade spent studying the upper atmosphere of Mars. As a dedicated Mars orbiter, it played a central role in advancing ...

NASA has lost contact with one of its three spacecraft orbiting Mars, the agency announced Tuesday. Meanwhile, a second Mars orbiter is perilously close to running out of fuel, and the third mission ...
