Mars Crater Offers Window on Temperatures 3.5 Billion Years Ago
Once upon a time, seasons in Gale Crater probably felt something like those in Iceland. But nobody was there to bundle up more than 3 billion years ago.
Field Geology at Mars’ Equator Points to Ancient Megaflood
Floods of unimaginable magnitude once washed through Gale Crater on Mars' equator around 4 billion years ago - a finding that hints at the possibility that life may have existed there, according to data collected by NASA's Curiosity rover and analyzed in joint project by scientists from Jackson State University, Cornell University, the Jet Propulsion Laboratory and the University of Hawaii.
Sustained Planetwide Storms May Have Filled Lakes and Rivers on Ancient Mars
A new study from The University of Texas at Austin is helping scientists piece together the ancient climate of Mars by revealing how much rainfall and snowmelt filled its lake beds and river valleys 3.5 billion to 4 billion years ago.
A New Look at Mars’ Eerie, Ultraviolet Nighttime Glow
Every night on Mars, when the sun sets and temperatures fall to minus 80 degrees Fahrenheit and below, an eerie phenomenon spreads across much of the planet's sky: a soft glow created by chemical reactions occurring tens of miles above the surface.
Ancient asteroid impacts created the ingredients of life on Earth and Mars
A new study reveals that asteroid impact sites in the ocean may possess a crucial link in explaining the formation of the essential molecules for life.
MAVEN maps electric currents around mars that are fundamental to atmospheric loss
Five years after NASA's MAVEN spacecraft entered into orbit around Mars, data from the mission has led to the creation of a map of...
