Carbon Detected In Martian Meteorites
2012-05-25 04:02:11

Lee Rannals for RedOrbit.com Carbon, a building block for creating life, has been detected in a Martian meteorite that landed on Earth, according to a Carnegie Institution for Science study. The researchers were able to detect strong evidence that complex carbon chemistry has taken place on Mars. "These findings show that the storage of reduced carbon molecules on Mars occurred throughout the planet's history and might have been similar to processes that occurred on the ancient...

[ Watch the Video ] Lee Rannals for RedOrbit.com NASA unleashed a new analysis of the giant asteroid Vesta on Thursday based on data taken by its Dawn spacecraft. Carol Raymond, Dawn deputy principal investigator at NASA´s Jet Propulsion Laboratory, said that Dawn's success has transformed scientists' perspective of Vesta from a fuzzy form, into a planetary body. She said that the asteroid formed within 2 million years after the first solids formed in the solar system....

Engineers Working Towards Laser Deflection Of Asteroids

Protecting the Earth from an extinction-threatening asteroid has in the past been left up to Hollywood, which has deployed a barrage of special effects box office blockbusters that have kept deadly space rocks from smashing our planet into oblivion. But now, Scottish engineers have come up with a plausible way of dealing with asteroids that doesn´t include Hollywood special effects. Engineers at the University of Strathclyde in Glasgow are developing an innovative technique based on...

By studying samples from carbon-rich meteorites, scientists with NASA's Goddard Space Flight Center say they have discovered that the building blocks of life can be created and maintained in extreme heat, not just in cooler conditions as had previously been believed. In a Friday press release, the U.S. space agency reports that experts from the Greenbelt, Maryland facility's Astrobiology Analytical Laboratory studied 14 samples and discovered "minerals that indicated they had experienced...

The Fireballs Of February
2012-02-23 04:23:03

Feb. 22, 2012:  In the middle of the night on February 13th, something disturbed the animal population of rural Portal, Georgia. Cows started mooing anxiously and local dogs howled at the sky. The cause of the commotion was a rock from space. "At 1:43 AM Eastern, I witnessed an amazing fireball," reports Portal resident Henry Strickland. "It was very large and lit up half the sky as it fragmented. The event set dogs barking and upset cattle, which began to make excited sounds. I...

When NASA's Dawn spacecraft entered orbit around giant asteroid Vesta in July, scientists fully expected the probe to reveal some surprising sights. But no one expected a 13-mile high mountain, two and a half times higher than Mount Everest, to be one of them. The existence of this towering peak could solve a longstanding mystery: How did so many pieces of Vesta end up right here on our own planet? For many years, researchers have been collecting Vesta meteorites from "fall sites"...

Image 1 - Meteorite Shockwaves Cause Martian Dust Avalanches

Dust avalanches around impact craters on Mars appear to be the result of the shock wave preceding the actual impact, according to a study led by an undergraduate student at the UA When a meteorite careens toward the dusty surface of the Red Planet, it kicks up dust and can cause avalanching even before the rock from outer space hits the ground, a research team led by an undergraduate student at the University of Arizona has discovered. "We expected that some of the streaks of dust that...

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...
