News Stories relating to "asteroid"

NASA plans to robotically capture a small near-Earth asteroid and redirect it safely to a stable orbit in the Earth-moon system where astronauts can visit and explore it. Is this part of NASA's search for potential "killer" asteroids?
At a recent Congressional hearing, NASA told lawmakers that it's time for...

That's the (rather unscientific) advice to Congress from NASA chief Charles Bolden, who basically says that if a large asteroid heads towards a big US city--as it recently did in Russia--there's not much else we can do. He told them, "From the information we have, we don't know of an asteroid that will threaten the population of the United...

It's like a video game in the sky: A joint mission between Europe and the US plans to slam a spacecraft into an asteroid in order to prove that incoming space rocks can be knocked off their paths before they collide with Earth.
The Asteroid impact and Deflection Assessment mission (AIDA) will intercept the asteroid Didymos in 2022,...

Will life on Mars go the way of the dinosaurs before we have a chance to discover it? Incoming Comet C213/A1, discovered on January 1st, is expected by some astronomers to pass within 28,000 miles of Marsin 2014. But cometary trajectories change, and an impact is not impossible, although NASA estimates that the object will pass Mars at a distance...

An aerospace and physics researcher has a plan to deflect a killer asteroid
by using paint. The idea may sound crazy, but he's working with NASA on the project.
Dave Hyland thinks that one possible way to avert an asteroid collision with Earth is by...

As Asteroid 2012 DA14 approached Earth, a significant meteor strike took place in central Russia. Most experts do not believe that the two events were related, and NASA has confirmed that the asteroid has not broken up. However, smaller debris is sometimes present near asteroids, and is not generally detectable, so it is possible that such debris...

Asteroid impacts are rare, but they can cause incredible harm
(look what one did to the dinosaurs
!). In 1908, one of them flattened 800 square miles in the...

That asteroid that hit the earth 13,000 years ago was a killer, all right--it triggered an ice age that wiped out most of the large animals on Earth. Melted glass buried deep within the Earth at sites around the world confirms the theory that a comet or meteor was responsible.
In the June 12th edition of the Los Angeles Times, Thomas...

A new gold rush is on! Google executives Larry Page and Eric Schmidt (along with filmmaker James Cameron) are backing a plan to mine gold and other precious metals
They've formed a company called Planetary Resources, which will start out by developing...

When US astronauts planted an American flag on the moon, it made other countries nervous because it seemed as if our country might be "claiming" it. Now space lawyers say that the international legal system must be improved and expanded before any products that are...

NASA may return to space after all--but not to explore, to MINE the valuable minerals that are on asteroids, in a NEW TYPE of "Gold Rush." And we may use robots to do the dirty work.
Space scientists think that robots will be the astronauts of the future. They'll explore the universe, find and identify...

Asteroid 255 YU55 will pass between the earth and the moon on Tuesday. The object is the larger than an aircraft carrier and would cause significant damage if it struck either our planet or the moon...

A group of scientists want to capture a near-earth asteroid and bring it closer to Earth, so we can use it as a platform for future space missions. This is not some wild future speculation
: We already have the technology to do this.

We recently had a close call
, and it turns out that the UK is one of the most vulnerable places on Earth, when it comes to an impact
from a space rock. Experts there have created a chart...

An asteroid the size of a city bus had a close call with earth on June 27th. The flyby was so close that it came nearer to us than some satellites are. LiveScience.com, Tariq Malik reports that the arriving space rock came closest to earth just after 1 pm Eastern Time, when it came within 7,500 miles of hitting us. Astronomers saw it coming on...

Comets make people crazy, and with the 2012 end-of-the-world scenario
in people's minds (NOTE: Subscribers

Astrobiologist Richard B. Hoover has discovered evidence of microfossils that resemble bacteria in fresh (so they couldn't have become contaminated later) slices of the interior surfaces of 3 carbon-filled meteorites
. After looking at them under an electron...

and meteors can come mighty close
. A 14-year-old German boy survived a direct hit by a meteorite after it fell to earth at 30,000 mph. Gerrit Blank was on his way to school when he saw "...

NASA has said that the asteroid Apophis ("The Uncreator") will have a close approach to the Earth in 2029, but will not fly close enough to strike us. However, a Russian astronomer disagrees. On the Helium website, Terrence Aym quotes Leonid Sokolov as saying, "Apophis will approach Earth at a distance of 37,000 to 38,000 kilometers...

When time slip expert Starfire Tor
joined Whitley on Coast to Coast AM on January 9, one of her predictions for 2011 was more meteor strikes. Her prediction has come true already: In Oklahoma, people recently star a "big ball of fire" streaking across the sky. It glowed slightly green, probably...

But they won't do it - There's almost nothing more scary than an asteroid impact--something that could turn us all instantly into ghosts (NOTE: Subscribers can still listen to this show). Millions of years ago, TWO asteroids did in the dinosaurs--will something similar happen to us?

Scientists have used quantum mechanics to reveal that the most common mineral on the surface of the earth is relatively UNcommon deep within the planet. Does this mean this material came to Earth by riding on the back of an asteroid?
Researcher Kevin Driver says, "Silica makes up two-thirds of the Earth
NOTE: This news...

BP may have been careless or parsimonious, but they certainly didn't want the huge oil link, and the terrible publicity (not to mention clean up costs) that have come along with it, to happen (or did they?). Every industry has near misses like this one. Sometimes they could have been prevented and sometimes, maybe not. Despite reports from the...

It's happening again: A near-Earth asteroid named 2005 YU55, which is on the list of potentially dangerous asteroids, was observed with the Arecibo Telescope's planetary radar on April 19, 2010 when it was about 1.5 million miles from the Earth, which is about 6 times the distance to the moon. Will there be an impact? Will someone help prevent...

Not with the Earth, but with EACH OTHER - X marks the spot: Asteroid impacts have wreaked havoc on this planet in the distant past (as well as probably bringing life here in the first place), but now that we have modern space telescopes, we can see two asteroids colliding with EACH OTHER. Should this worry us?
