NASA Is Smarter Than Dinosaurs

Thursday, June 20, 2013


NASA says the community can show humans are "smarter than the dinosaurs" by serving them situating asteroids that have the possible to end the person pursuit.
The dinosaurs were extremely killed off by an asteroid bang about 66 million years ago, and humans could one day appearance a comparable danger.
"NASA previously is functioning to discover asteroids that capacity is a menace to our planet, and while we have established 95 percent of the large asteroids near the Earth's orbit, we want to find all those that might be a threat to Earth," says deputy administrator Lori Garver.
"This grand challenge is paying attention on detecting and characterizing asteroids and learning how to deal with possible coercion. We will also connect public rendezvous, open modernism and citizen science to help solve this global problem."
The mission has backing from the White House, which says the hunt for killer asteroids requires an "all-hands-on-deck effort".
"The efforts of private-sector partners and our citizen scientists will augment the work NASA already is doing to improve near-Earth object detection capabilities," says Tom Kalil, deputy director for technology and innovation at the White House Office of Science and Technology Policy
NASA estimates it has only found a quarter of near-Earth asteroids larger than 100m in diameter. Those larger than about 140m could destroy an entire city, if they hit at the right angle and speed. An asteroid that exploded above the Russian city of Chelyabinsk earlier this year, injuring hundreds, was only about 15m across.
"This is really a call to action to find all asteroid threats to human populations and know what to do about them;" says Ms Garver, adding that a successful deflection would prove "we're smarter than the dinosaurs".
NASA is also looking for ideas and in sequence on how it can achieve its other asteroid-related goal capturing one and bringing it into orbit around the moon.

Dinosaurs Killed by Thousand Year Long Meteor Shower

Monday, August 30, 2010


Were the dinosaurs killed by an ice age? A meteor shower? Aliens? A new study shows that dinosaurs were likely killed by a meteor shower, but not one that sent a few rocks to earth. The meteor shower that killed the dinosaurs lasted thousands of years.

Previously, scientists believed that a single meteor strike killed the dinosaurs. The giant Chicxulub crater in the Gulf of Mexico is usually regarded as the site of the dino-killing meteor strike, but an impact crater in the Ukraine is making scientists rethink their meteor shower theory.

The Telegraph reports that the crater in the Ukraine, the Boltysh Crater, predates the Chicxulub crater by thousands of years. A new crater which was found inside the Boltysh Crater, has led scientists to believe that the meteor shower that killed the dinosaurs was not a one time occurrence, but a shower that spanned over thousands of years.

Whether one or hundreds of meteors killed the dinosaurs, will continue to be debated, but in the meantime, NASA has developed a program to make sure that we don't meet the same fate. The SpaceGuard program keeps a watchful eye on the sky in an attempt to give us early warning of a meteor impact.

But as of now, detection is the only part of the SpaceGuard program that has been completely fleshed out. Deflecting a meteor is another problem entirely, and the only answers to that problem are coming from Hollywood.
