Rocks on Mars dug from far underground by crater-blasting impacts are providing glimpses of one possible way Mars' atmosphere has become much less dense than it used to be. At several places where cratering has exposed material from depths of about 5 kilometers (3 miles) or more beneath the surface, observations by a mineral-mapping instrument on NASA's Mars Reconnaissance Orbiter indicate carbonate minerals. These are not the first detections of carbonates on Mars. However, compared to...

A table-top gamma-ray detector created at the University of Michigan can not only identify the presence of dangerous nuclear materials, but can pinpoint and show their exact location and type, unlike conventional detectors. "Other gamma ray detectors can tell you perhaps that nuclear materials are near a building, but with our detector, you can know the materials are in room A, or room B, for example," said Zhong He, an associate professor in the Department of Nuclear Engineering and...

Minerals in northern Mars craters seen by two orbiters suggest that a phase in Mars' early history with conditions favorable to life occurred globally, not just in the south. Southern and northern Mars differ in many ways, so the extent to which they shared ancient environments has been open to question. In recent years, the European Space Agency's Mars Express orbiter and NASA's Mars Reconnaissance Orbiter have found clay minerals that are signatures of a wet environment at thousands of...

The Special Sensor Ultraviolet Limb Imager (SSULI) developed by NRL's Spacecraft Engineering Department and Space Science Division, launched October 18, 2009 on the U.S. Air Force Defense Meteorological Satellite Program (DMSP) F18 (flight 18) satellite, observed first light on December 1, 2009. In a sample airglow profile the spectral emission features in the data are clean and show no anomalies. "The SSULI team is very excited to continue with early orbit testing and begin the calibration...

The SCIAMACHY sensor on ESA's Envisat satellite has provided scientists with invaluable data on our planet, allowing them to map global air pollution and the distribution of the most important greenhouse gases. Earlier this year, its sights were set on our nearest planetary neighbor, Venus. In March and June, SCIAMACHY (Scanning Imaging Spectrometer for Atmospheric Chartography) captured visible and near-infrared spectra of sunlight reflected by Venus. These observations, acquired from a...

Astronomers have announced plans to build an ultra-stable, high-precision spectrograph for the Science and Technology Facilities Council's 4.2-m William Herschel Telescope (WHT - part of the Isaac Newton Group or ING on La Palma) in an effort to discover habitable Earth-like planets around other stars. Dr Ian Skillen of the ING will present the new High Accuracy Radial-velocity Planet Search "“ New Earths Facility (HARPS-NEF) spectrograph in a poster on Monday 20th April at the European...

Researchers using a powerful instrument aboard NASA's Mars Reconnaissance Orbiter have found a long sought-after mineral on the Martian surface and, with it, unexpected clues to the Red Planet's watery past. Surveying intact bedrock layers with the Compact Reconnaissance Imaging Spectrometer for Mars, or CRISM, scientists found carbonate minerals, indicating that Mars had neutral to alkaline water when the minerals formed at these locations more than 3.6 billion years ago. Carbonates, which...

New findings show diverse, wet environments on ancient Mars WASHINGTON, July 16 (Xinhua) -- Mars once hosted vast lakes, flowing rivers and a variety of other wet environments that had the potential to support life, according to two new studies based on data from instruments on board NASA's Mars Reconnaissance Orbiter (MRO). By combining data from these high-tech instruments, scientists have identified three principal classes of water-related minerals dating to the early history of...
