HiRISE: Better preserved on Mars than on Earth
In many ways, Mars bears remarkable similarities to Earth, but in some ways it is drastically different. Scientists often use Earth as an example, or analog, to help us to understand the geologic history of the Red Planet. As we … Continue reading

HiRISE: Beauty of layered stratigraphy
The layered bedrock in this image was brought from several kilometers of depth during the formation of this 44 kilometer wide crater in the volcanic plains of Lunae Planum. As these layers were exhumed and brought to nearly vertical orientations, … Continue reading
Does Black Beauty represent bulk of Mars crust?
New spectroscopic analysis of “Black Beauty,” a meteorite found in the Moroccan desert, has given scientists a better picture of the crust beneath Mars’ red dust. The meteorite, also known as NWA 7034, is like no other rock ever found … Continue reading
‘Black Beauty’ zircons record ancient Mars climate
Was Mars — now a cold, dry place — once a warm, wet planet that sustained life? And if so, how long has it been cold and dry? … By analyzing the chemical clues locked inside an ancient Martian meteorite … Continue reading

HiRISE: Big block of red bedrock
This image covers a 26-kilometer-wide impact crater northeast of the Hellas impact basin. The crater exposes large blocks of bedrock (called “megabreccia”) in both the central uplift and in the walls of the crater. The enhanced-color subimage from the wall … Continue reading

“Black Beauty” Mars meteorite unique
It’s young, it has been shattered and naturally recemented, and it’s about ten times richer in water than any other Mars meteorite. And if the scientists who studied it are right, it’s the also first meteorite to come from the … Continue reading
