Data will help scientists read Curiosity Mars rover samples for signs of life, says UMD coauthor of study published today in Nature. (PRWEB) April 16, 2014 Geologists who analyzed 40 meteorites that fell to Earth from Mars unlocked secrets of the Martian atmosphere hidden in the chemical signatures of these ancient rocks. Their study, published April 17 in the journal Nature, shows that the atmospheres of Mars and Earth diverged in important ways very early in the 4.6 billion year...

Small Asteroid Regolith Formed By Thermal Fatigue
2014-04-04 06:21:44

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Small asteroids contain a layer of loose, unconsolidated rock and dust known as a regolith composed of centimeter-sized fragments and smaller particles. New research from researchers at the Observatoire de la Côte d'Azur, Hopkins Extreme Materials Institute at Johns Hopkins University, Institut Supérieur de l'Aéronautique et de l'Espace and Southwest Research Institute (SwRI), have now determined that this layer is formed by...

NASA Scientists Find Evidence Of Water In Martian Meteorite
2014-02-28 07:16:06

Lawrence LeBlond for redOrbit.com - Your Universe Online Evidence of water and life on Mars is a hotly debated topic that has been ongoing for decades. While most scientists agree that Mars had an abundant source of water in its ancient past, there has only been limited evidence that life may have once existed on the Red Planet. However, scientists from NASA’ Johnson Space Center in Houston and the Jet Propulsion Laboratory in Pasadena, California have found evidence of past water...

[ Watch the Video: New Technique For Studying Out-Of-This-World Particles ] Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists have long delved into the mysteries of the origins of life here on Earth and more recently have found evidence pointing to the skies above us. Some evidence has been found in material created in space and delivered to Earth via comets and meteors, containing the building blocks for life. The latest round of evidence comes by way of Michael...

Meteorite Reveals Martian Secrets
2013-11-21 07:06:46

April Flowers for redOrbit.com - Your Universe Online A new study has uncovered what may be the first recognized example of ancient Martian crust. The findings, published in Nature, are the work of Munir Humayun of Florida State University. His work is based on an analysis of a 4.4 billion-year-old Martian meteorite unearthed by Bedouin tribesmen in the Sahara desert. The rock, designated NWA 7533, might be the first recognized sample of ancient Martian crust and holds a wealth of...

Crater -- A crater is a circular depression on the surface of a planet, moon, asteroid, or other celestial body. Craters are typically caused by meteorite impacts, although some are caused by volcanic activity. In the center of craters on Earth a crater lake often accumulates, and in craters formed by meteorites a central island (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake. Ancient craters whose relief has disappeared leaving only a...
