This happens during Saturn's equinox, when the sun is directly over Saturn's equator. At this time, the rings, which also orbit directly over the planet's equator, appear edge-on to the...
Physics and Astronomy |Images from one of the Magnetospheric Imaging Instrument’s sensors, the Ion and Neutral Camera (MIMI/INCA), on NASA’s Cassini spacecraft suggest that the heliosphere may not have the comet-like shape ...
Physics and Astronomy |The event is the highlight of NASA's Lunar Crater Observation and Sensing Satellite (LCROSS) mission. The LCROSS spacecraft flies behind its empty upper stage, which is targeted to strike the flo...
Physics and Astronomy |"We knew there was ice below the surface at high latitudes of Mars, but we find that it extends far closer to the equator than you would think, based on Mars' climate today," said Shane...
Earth Sciences |NASA's Lunar Reconnaissance Orbiter (LRO), an unmanned mission to comprehensively map the entire moon, has returned its first data. One of the seven instruments aboard, the Diviner Lunar Radiomet...
Physics and Astronomy |The joint NASA/ESA/ASI Cassini-Huygens mission has revealed details of Titan's geologically young surface, showing few impact craters, and featuring mountain chains, dunes and even "lakes&qu...
Earth Sciences |Yesterday (2 July 2009) the Lunar Reconnaissance Orbiter (LRO) - the American mission which left Cape Canaveral on 18 June 2009 with the aim of preparing a manned return to the moon - transmitted the ...
Physics and Astronomy |The maneuver to change Odyssey's orbit began Sept. 30, 2008, and ended June 9, 2009, with a five-and-a-half-minute thruster firing. The rocket burn fixed the spacecraft's track so that THEMI...
Physics and Astronomy |A University of Colorado at Boulder research team has discovered the first definitive evidence of shorelines on Mars, an indication of a deep, ancient lake there and a finding with implications for th...
Earth Sciences |For nearly two years, professor Mark Robinson and his team have called this building home, developing it into a state-of-the-art Science Operations Center (referred to as the SOC) to work in conjuncti...
Physics and Astronomy |"I've booked my flight to Florida, I can hardly wait for things to get going," says Prof. Harald Hiesinger from the Institute of Planetology at Münster University, who is looking forwar...
Physics and Astronomy |Arizona State University researchers and scientists have created two new features for Google Earth 5.0, the popular online application that lets users tour Earth, the starry sky, and the Red Planet M...
Physics and Astronomy |Opportunity’s two-year exploration of Victoria Crater – a half-mile wide and 250 feet deep – yielded a treasury of information about the planet’s geologic history and supported previous findings indic...
Physics and Astronomy |Compiled by Helmut Lammer, PhD, Senior Editor of Astrobiology, from the Austrian Academy of Sciences, this special paper collection features a report by Pham et al. that presents a semi-analytical mod...
Physics and Astronomy |Gullies are known to be young surface features on Mars. But scientists studying the planet have struggled with locating gullies they can conclusively date. In a paper that appears on the cover of the ...
