MAVEN News & Features
After a decade of searching, NASA’s MAVEN (Mars Atmosphere Volatile Evolution) mission has, for the first time, reported a direct observation of an elusive atmospheric escape process called sputtering that could help answer longstanding questions about the history of water…
On March 15, 2024, near the peak of the current solar cycle, the Sun produced a solar flare and an accompanying coronal mass ejection (CME), a massive explosion of gas and magnetic energy that carries with it large amounts of…
One year on, NASA scientists are still making huge discoveries about the largest geomagnetic storm to hit Earth in two decades, the Gannon storm. The findings are helping us better understand and prepare for the ways in which the Sun’s…
A decade ago, on Sept. 21, 2014, NASA’s MAVEN (Mars Atmospheric and Volatile EvolutioN) spacecraft entered orbit around Mars, beginning its ongoing exploration of the Red Planet’s upper atmosphere. The mission has produced a wealth of data about how Mars’…
Mars was once a very wet planet as is evident in its surface geological features. Scientists know that over the last 3 billion years, at least some water went deep underground, but what happened to the rest? Now, NASA’s Hubble…
Scientists from around the world are gathering this week in California to take stock of the state of science from Mars and discuss goals for the next steps in exploration of the Red Planet. In the spirit of Mars 10,…
In addition to producing auroras, a recent extreme storm provided more detail on how much radiation future astronauts could encounter on the Red Planet. Mars scientists have been anticipating epic solar storms ever since the Sun entered a period of…
The Sun will be at peak activity this year, providing a rare opportunity to study how solar storms and radiation could affect future astronauts on the Red Planet. In the months ahead, two of NASA’s Mars spacecraft will have an…
There’s good news from NASA’s Cloudspotting on Mars project! That’s the project that invites you to help identify exotic clouds high in the Martian atmosphere. Congratulations to the Cloudspotting on Mars team and all the volunteers who have helped spot Martian clouds!
April 17, 2021, was a day like any other day on the Sun, until a brilliant flash erupted and an enormous cloud of solar material billowed away from our star. Such outbursts from the Sun are not unusual, but this…
