Spectacular New Crater and Ejecta on Mars|
February 6, 2014 | NASA.gov
“Space rocks hitting Mars excavate fresh craters at a pace of more than 200 per year, but few new Mars scars pack as much visual punch as one seen in a NASA image released today.” Quoted from the NASA press release (February 5, 2014).
Surprise White Rock on Mars|
January 23, 2014 | NASA
While preparing to start robotic arm work on the target “Cape Elizabeth” on Sol 3541 (Jan. 8, 2014), Opportunity encountered a slight surprise — a rock had appeared in the images that had not been there before. This target that has been named “Pinnacle Island” and its origin has been the target of much speculation.
Dating Rocks on Mars|
December 29, 2013 | Caltech
“Although researchers have determined the ages of rocks from other planetary bodies, the actual experiments—like analyzing meteorites and moon rocks—have always been done on Earth. Now, for the first time, researchers have successfully determined the age of a Martian rock—with experiments performed on Mars.” Quoted from the Caltech press release.
Megafloods in Idaho and on Mars|
December 26, 2013 | Caltech
“South-central Idaho and the surface of Mars have an interesting geological feature in common: amphitheater-headed canyons. These U-shaped canyons with tall vertical headwalls are found near the Snake River in Idaho as well as on the surface of Mars. Various explanations for how these canyons formed have been offered—some for Mars, some for Idaho, some for both. [...] Kenneth A. Farley offers a plausible account that all these canyons were created by enormous floods.” Quoted from the Caltech press release.
Seasonal Changes on Mars|
December 12, 2013 | NASA
“NASA’s Mars Reconnaissance Orbiter has revealed to scientists slender dark markings — possibly due to salty water – that advance seasonally down slopes surprisingly close to the Martian equator.” Quoted from the NASA press release.
Ancient Lake in the Gale Crater on Mars?|
December 10, 2013 | NASA
“This illustration depicts a concept for the possible extent of an ancient lake inside Gale Crater. The existence of a lake there billions of years ago was confirmed from examination of mudstone in the crater’s Yellowknife Bay area.”
Granite on Mars?|
November 20, 2013 | Georgia Tech
“Researchers now have stronger evidence of granite on Mars and a new theory for how the granite – an igneous rock common on Earth — could have formed there. The findings suggest a much more geologically complex Mars than previously believed.” Quoted from the Georgia Tech press release.

Did the Lower Crust Flow on Mars?|
July 19, 2013 | Speaking of Geoscience Blog
“In particular, the southeast region of Tharsis bears strong resemblance in structure and topography to eastern Tibet. High topography and thick crust of eastern Tibet produces long, low-gradient plateau margins that may be caused by the flow of weakened lower crust. This has me thinking: if the lower crust flows in Tibet, did it do so on Mars?” Quoted from the Speaking of Geoscience article.

Wind Deposits Three Miles Thick?|
May 8, 2013 | Princeton University
“A roughly 3.5-mile high Martian mound that scientists suspect preserves evidence of a massive lake might actually have formed as a result of the Red Planet’s famously dusty atmosphere, an analysis of the mound’s features suggests.” Quoted from the Princeton University press release.
Mars Drilling Site|
April 11, 2013 | NASA
“This image shows the first holes into rock drilled by NASA’s Mars rover Curiosity, with drill tailings around the holes plus piles of powdered rock collected from the deeper hole and later discarded after other portions of the sample had been delivered to analytical instruments inside the rover.”
USGS Crowd-Sourcing Test|
April 5, 2013 | USGS
“Over a trial period of ten months, 143 volunteers collected, improved, or deleted data on more than 6,400 structures in Colorado. The volunteers’ actions were accurate and exceeded USGS quality standards. In the Colorado pilot project the volunteer-collected data showed an improvement of approximately 25 percent in both location and attribute accuracy for existing data points. Completeness, or the extent to which all appropriate features were identified and recorded, was nearly perfect.” Quoted from the USGS summary.
