Gravity field map of the moon generated by GRAIL probes boosts Giant impact hypothesis, which states that the Moon was formed out of the debris left over from a collision between the Earth and a body the size of Mars, about 4.5 billion years ago. This new map is also
The Earth never sleeps. The night is nowhere near as dark as most of us think. In fact, Earth is never really dark; it twinkles with lights from humans and nature. Away from human settlements, light still shines – wildfires and volcanoes rage, oil and gas wells burn
NASA scientists have announced entry of Voyager 1 in a new region in deep space, which they’re calling a magnetic highway for charged particles; presumably the last leg of Voyager mission’s journey. In this region, magnetic field lines of sun are found connected to
This weekend the International Space Station will turn itself to position ESA’s SOLAR instrument for a better view of the Sun. This would be the first time ISS has changed attitude for scientific reasons alone.SOLAR instrument was installed on ESA’s Columbus
“The Gravity field and steady-state Ocean Circulation Explorer” or GOCE, has been orbiting Earth since March 2009, with objective to map our planet’s gravity. In order to improve the quality of the gravity model, maximise its sensitivity to variations in Earth’s
Rise of atmospheric carbon dioxide in upper level of Earth’s atmosphere is expected to gradually result in a cooler, more contracted high-altitude atmospheric layer or thermosphere, and a consequent reduction in the atmospheric drag experienced by satellites,
Mars rover Curiosity has completed the first-ever detailed X-ray analysis of Martian sand showing the mineralogy of Martian soil is similar to weathered basaltic soils of volcanic origin in Hawaii.Curiosity used its Chemistry and Mineralogy instrument (CheMin) to
ESA’s new deep-space mission tracking station is nearing inauguration in Malargüe, Argentina, 1000 km west of Buenos Aires. Deep Space Antenna 3 (DSA 3) will ensure reliable communications with missions voyaging hundreds of millions of kilometres into our Solar
Since Sentinels of the Heliosphere in 2008, there have been a few new missions, and a few missions have been shut down. As of Fall of 2012, here’s a tour of the NASA Near-Earth Heliophysics fleet, covering the space from near-Earth orbit out to the orbit of the
Yesterday NASA revealed some really intriguing radar images of Titan’s terrain captured by Cassini spacecraft’s radar instrument during its May 22 flyby, which recently completed its 15 years in space. One of them depicts a giant, nearly circular mound which looks like
