A paper published today in the journal Icarus identifies distinct deposits of minerals called carbonates along the inner rim of Jezero, the site of a lake more than 3.5 billion years ago. On Earth, carbonates help form structures that are hardy enough to survive in fossil form for billions of years, including seashells, coral and some stromatolites – rocks formed on this planet by ancient microbial life along ancient shorelines, where sunlight and water were plentiful. ![]() NASA’s Mars 2020 Will Hunt for Microscopic Fossils Lighter colors represent higher elevation in this image of Jezero Crater on Mars, the landing site for NASA’s Mars 2020 mission. The oval indicates the landing ellipse, where the rover will be touching down on Mars. (NASA) «Read the rest of this article» Sections: Technology | No Comments

NASA picks 10 Studies for future CubeSat missionsWritten by Andrew Good
For these studies, small satellites are defined as less than 180 kilograms in mass (about 400 pounds). CubeSats are built to standard specifications of 1 unit (U), which is equal to about 4x4x4 inches (10x10x10 centimeters). They often are launched into orbit as auxiliary payloads, significantly reducing costs. ![]() A global view of Venus created from Magellan data and a computer-simulated globe. A JPL-led mission concept study was recently selected to study Venus using a Cubesat. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA researchers say Mars may have had RingsWritten by Brian Wallheimer
That’s the theory put forth by NASA-funded scientists at Purdue University, Lafayette, Indiana, whose findings were published in the journal Nature Geoscience. David Minton and Andrew Hesselbrock developed a model that suggests that debris that was pushed into space from an asteroid or other body slamming into Mars around 4.3 billion years ago alternates between becoming a planetary ring and clumping together to form a moon. ![]() This sequence of images from NASA’s Curiosity Mars rover shows one of Mars’ two moons, Phobos, passing directly in front of the other, Deimos, in 2013.

NASA’s Mars Reconnaissance Orbiter discovers evidence of Ancient Volcanoes on MarsWritten by Guy Webster
The research about these volcanoes helps show there was extensive ice on ancient Mars. It also adds information about an environment combining heat and moisture, which could have provided favorable conditions for microbial life. Sheridan Ackiss of Purdue University, West Lafayette, Indiana, and collaborators used the orbiter’s mineral-mapping spectrometer to investigate surface composition in an oddly textured region of southern Mars called “Sisyphi Montes.” ![]() This graphic illustrates where Mars mineral-mapping from orbit has detected minerals that can indicate where a volcano erupted beneath an ice sheet. The site is far from any ice sheet on modern Mars, in an area where unusual shapes have been interpreted as a possible result of volcanism under ice.

NASA picks Researchers to take part in Curiosity Mars Rover missionWritten by Guy Webster
The six new additions work in Alabama, Colorado, Indiana, Pennsylvania, Michigan and Tennessee. Eighty-nine scientists around the world submitted research proposals for using data from Curiosity and becoming participating scientists on the Mars Science Laboratory Project, which built and operates the rover. ![]() Patches of Martian sandstone visible in the lower-left and upper portions of this March 9, 2016, view from the Mast Camera of NASA’s Curiosity Mars rover have a knobbly texture due to nodules apparently more resistant to erosion than the host rock in which some are still embedded.
