A new study, led by a team at Boston University, is offering new insights into how the Sun’s relentless solar wind—a stream of high-speed charged particles—removes Mars’ atmosphere. Since Mars is ...

Mars just gave up one of its oldest secrets — and it took a decade, a spacecraft, and a cosmic cannonball to catch it in the act. For the first time, NASA's MAVEN mission has directly observed a ...

Our sun constantly releases a stream of high-speed charged particles, known as the solar wind. Unlike Earth, Mars does not have a strong global magnetic field to shield its atmosphere from this flow.

For years, scientists have puzzled over how Mars lost the thick atmosphere it once had. That atmosphere was essential for liquid water to exist on the planet's surface, billions of years ago. Today, ...

It's not entirely clear how neighboring planet Mars went from a presumably life-supporting planet to a place as dead as all others in the solar system. We do know, however, that whatever water and ...

How has Mars lost its atmosphere over time? This is what a recent study published in Science Advances hopes to address as a team of scientists investigated a connection between the solar wind the Mars ...

HOUSTON—Scientists assigned to NASA’s Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft have quantified the red planet’s loss of atmosphere to the forces of the solar wind and radiation, ...

Our Sun constantly releases a stream of high-speed charged particles, known as the solar wind. Unlike Earth, Mars does not have a strong global magnetic field to shield its atmosphere from this flow.

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 ...
