WASHINGTON, May 15, 2013 /PRNewswire-USNewswire/ -- Scientists using images from NASA's Mars Reconnaissance Orbiter (MRO) have estimated that the planet is bombarded by more than 200 small asteroids or bits of comets per year forming craters at least 12.8 feet (3.9 meters) across.

Underground Explosions Responsible For Pits Inside Twin Craters On Mars
2013-04-11 11:32:25

ESA Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside these two large martian impact craters, imaged by ESA´s Mars Express on 4 January. The ℠twin´ craters are in the Thaumasia Planum region, a large plateau that lies immediately to the south of Valles Marineris, the largest canyon in the Solar System. The northernmost (right) large crater in this scene was officially given the name Arima in early 2012, but the southernmost...

3-D Image Of Buried Mars Flood Channels
2013-03-08 05:54:03

April Flowers for redOrbit.com - Your Universe Online For the first time ever, new maps of the subsurface of Mars show buried channels below the surface of the planet. These channels suggest evidence of flooding on a planet that has been considered by scientists to be cold and dry for the last 2.5 billion years. The young channels are located in Elysium Planitia, an expanse of plains along the equator. This region is also the youngest volcanic region on Mars. Understanding the scale and...

WASHINGTON, March 7, 2013 /PRNewswire-USNewswire/ -- NASA's Mars Reconnaissance Orbiter (MRO) has provided images allowing scientists for the first time to create a 3-D reconstruction of ancient water channels below the Martian surface. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO ) The spacecraft took numerous images during the past few years that showed channels attributed to catastrophic flooding in the last 500 million years. Mars during this period had been considered...

Using 3D Printing Technology To Build A Lunar Base
2013-02-01 15:16:12

Lee Rannals for redOrbit.com — Your Universe Online Three-dimensional printing is growing rampantly and the European Space Agency (ESA) has decided to utilize the up-and-coming technology to build a base on the moon using lunar soil. ESA is partnering with industrial partners, including architects Foster + Partners, to see if the idea of building a lunar habitat on the moon is a feasible one. Foster + Partners created a dome with a cellular structured wall that could help to...

Mars Express Orbiter Snaps Image Of River-Like Formation On Surface Below
2013-01-18 16:04:26

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency's (ESA) Mars Express has offered up a high-resolution photo of a river-like structure on Mars. The spacecraft used its high-resolution stereo camera last year to snap an image of Reull Vallis on the Red Planet. Reull Vallis is a river-like structure believed to have formed when running water flowed in the distant martian past. The ancient river bed cuts a steep-sided channel through the Promethei...

Earth’s Magma Mantle Melts Hotter Than Previously Thought
2013-01-10 10:10:41

April Flowers for redOrbit.com - Your Universe Online According to a new study by researchers at Rice University, the Earth's mantle magma melts far hotter and deeper in the Earth's core than previously thought, a discovery that will have lasting implications for our understanding of the planet's geophysical and geochemical properties. The research team, led by Rajdeep Dasgupta, put small amounts of peridotite under large pressures in a laboratory to determine that rock can and does...

Disney Name Goes Interplanetary With Impact Crater Identity
2012-12-21 13:55:02

Lee Rannals for redOrbit.com - Your Universe Online Mercury has gained a little more fame in the eyes of Hollywood, after the International Astronomical Union (IAU) agreed to name nine impact craters after Walt Disney. The MESSENGER Science Team proposed nine names for impact craters on Mercury, all of which refer to either a blues singer, animation pioneer Walter Elias "Walt" Disney, or other artists. IAU has been the gatekeeper for planetary and satellite nomenclature since 1919,...

Ancient Mars Caverns May Have Captured Flood Water
2012-12-05 16:24:33

Lee Rannals for redOrbit.com — Your Universe Online Researchers have found evidence that ancient caverns on Mars may have captured enormous flood waters some 2 billion years ago. Planetary Science Institute researchers studied the terminal regions of the Hebrus Valles, which is an outflow channel that extends about 155 miles downstream from two zones of surface collapse. The Martian outflow channels are made up of some of the largest known channels in the solar system....

Moon Formation - Evidence Backs Up Giant Impact Theory
2012-10-17 14:15:54

[ Watch the Video: What is the Moon? ] | [ Watch the Video: Planetary Demolition Derby ] Lee Rannals for redOrbit.com - Your Universe Online Scientists are backing up a theory, claiming that the Moon was created when a planetary body the size of Mars collided with Earth. Planetary scientists found evidence that backs up the Giant Impact Theory, which was first proposed at a conference in 1975. The Giant Impact Theory says that Earth´s moon was created in an apocalyptic...

Harrison Schmitt was a NASA astronaut, and is also an American geologist. He was born Harrison Hagan "Jack" Schmitt on July 3, 1935 in Santa Rita, New Mexico. After high school, he went to the California Institute of Technology and received a B.S. degree in science in 1957. He then went to Norway to study geology at the University of Oslo. In 1964, Schmitt earned a Ph.D. in geology from Harvard University. After receiving his doctorate, he worked at the U.S. Geological Survey's...

The Planet Venus is the second planet from the sun. It is often called the evening star or morning star and is brighter than any object in the sky except the sun and the moon. Because its orbit lies between the sun and the orbit of the earth, Venus passes through phases like those of the moon, varying from a large bright crescent when the planet is near inferior conjunction (nearest the earth) to a smaller silvery disk when it is at superior conjunction (farthest from the earth). Since...
