Proposals are being considered at NASA for a mission to an asteroid to study asteroid composition and movements. A NASA feasibility study showed that such an asteroid mission is possible with the new vehicles NASA is developing for a trip to the moon.

Earth can breathe a sigh of relief. NASA on Wednesday downgraded the odds of an 885-foot asteroid striking the planet in 2036. Scientists initially believed there was a 1-in-45,000 chance that Apophis could hit the planet on April 13, 2036. But the threat was lowered to a 1-in-250,000 chance after researchers recalculated the asteroid's path. "It wasn't anything to worry about before. Now it's even less so," said Steve Chesley, an astronomer with the Near Earth Object Program at NASA's Jet Propulsion Laboratory. Chesley and his colleagues refined the asteroid's orbit after an astronomer in Hawaii analyzed previously unreleased images that gave scientists a ... Read Full Story

Image Credit: Don Davis/NASA Using updated information, NASA scientists have recalculated the path of a large asteroid. The refined path indicates a significantly reduced likelihood of a hazardous encounter with Earth in 2036. The Apophis asteroid is approximately the size of two-and-a-half football fields. The new data were documented by near-Earth object scientists Steve Chesley and Paul Chodas at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. They will present their updated findings at a meeting of the American Astronomical Society’s Division for Planetary Sciences in Puerto Rico on Oct. 8. “Apophis has been one of those celestial bodies that has captured the public’s interest ...

The first images from Rosetta’s OSIRIS imaging system and VIRTIS infrared spectrometer were derived from raw data and have delivered breathtaking results. "Steins looks like a diamond in the sky," said Uwe Keller, Principal Investigator for the OSIRIS imaging system from the Max Planck Institute. Visible in the image are several small craters on the asteroid, and two huge ones, one of which is 2 km in diameter, indicating that the asteroid must be very old. Rita Schulz, Rosetta Project Scientist, said, "In the images is a chain of impact craters, which must have formed from recurring impact as the asteroid rotated. The impact ... Read Full Story

This sounds like something from a science fiction movie, but it is a real threat to the whole planet. It can happen any time. A medium sized asteroid of a few kilometers in diameter crashing into the Earth can completely destroy our civilization and exterminate the whole human race, just like it happened to the dinosaurs. But fortunately there are some ways to prevent all this. The human race is at the point that it can prevent it’s own extinction. There are numerous ways of deflecting such an asteroid to a safer orbit, but it has to be spotted years before potential impact, otherwise ... Read Full Story

The energy recorded was estimated to be 0.9 to 1.0 kT of TNT and the time of detection was 02:45:45 on October 7 (Greenwich Standard Time). More details on this detection will be forthcoming. An additional confirmation was apparently reported by a KLM airliner as reported by Peter Brown (University of Western Ontario, Canada), a preliminary examination ... Read Full Story

Hopes are fading for the return of the Hayabusa space probe after another of its ion thrusters failed last week, leaving just one already-damaged engine to guide the hard-luck spacecraft back to Earth.

SPACE.com - A fireball over Utah overnight Tuesday was the talk of the state. And an asteroid that could have delivered nearly half the energy of the Hiroshima atom bomb whizzed past Earth earlier this month, NASA reported recently. Meanwhile, a meteor shower dazzled skywatchers around the globe early Tuesday morning.

Even before swine flu hysteria comes to an end, momentum is building behind the next Internet-driven global threat to human health and well-being. NASA has received so many inquiries about an impending planetary collision (which of course is being kept quiet via a Huge International Conspiracy of Alarming Proportions) that it has launched a web page to respond to them: Question (Q): Are there any threats to the Earth in 2012? Many Internet...

Did you hear about this? Last Friday, November 6, 2009 an asteroid named 2009 VA and about 7 meters across passed about one Earth diameter away.  That’s a mere whisker.  In fact, NASA is saying this is the third-closest known (non-impacting) Earth approach on record.  NASA estimates an asteroid of this size does impact the Earth [...]

In October 2009 , one asteroid of radius 10 meters came very close to earth to the point that in a city of indonesia , fire balls were visible which resulted from asteroif getting burnt , even in november another huge asteroid came as close as few thousand miles to earth and in both this occasion...

Launched in 2003, Japan's Hayabusa was supposed to travel 2 billion kilometres and bring back samples from an asteroid. It would be a world's first asteroid sample return mission, but in November 2005, following encouraging news that Hayabusa had landed on the asteroid (named Itokawa), JAXA officials expressed serious doubt over whether it was actually able to get any rocks (see: A shot in the dark?). A loss of communication in December 2005...
