NASA scientist wants to build a new telescope to protect the Earth from the dangerous space rocks that the dinosaurs have eradicated
- The scientist has presented the Near-Earth Object Camera (NEOCam) to NASA
- These can search for asteroids through the heat-emitted telescopes instead of light
- The detection would be more accurate because asteroid light is often & # 39; blurred & # 39; could be
- It could rather find asteroids and give scientists time to come up with a strategy
A top atlas from NASA has said that the best way to protect the Earth from asteroids is to build a new telescope that it can observe as quickly as possible.
Dr. Amy Mainzer of NASA & # 39; s Jet Propulsion Laboratory in Pasadena, California, said trying to see asteroids with current telescopes was like having a & # 39; lump of coal in the night sky & # 39; tried to find.
Her team has proposed a new system to identify large meteorites that can cause significant damage.
It would identify incoming asteroids that are capable of causing enormous loss of life – just like the meteor who wiped out the dinosaurs 66 million years ago.
They claim that this would give scientists more time to come up with a strategy to intercept the stone.

A NASA scientist has said that defending the earth against dangerous asteroids is to detect them via heat using an infrared telescope called the Near-Earth Object Camera (NEOCam). Comet Catalina (photo) was captured in 2015 by such a telescope, called NEOWISE
Dr. Mainzer warned that today's telescopes are not effective when it comes to spotting asteroids until it's too late to prevent them from hitting our planet in a potentially catastrophic way.
The Chelyabinsk meteor, which was only 17 to 20 meters wide, caused extensive ground damage and numerous injuries when it exploded after a collision with the Earth's atmosphere in February 2013.
While the asteroid that hit the earth and killed the dinosaurs about 65 million years ago was about 10 kilometers wide.
Detecting these Near-Earth Objects – NEOs over time means preventing such tragedies for humanity, but spotting them is often the problem.
Dr. Mainzer compared finding NEO's in space, such as spotting a lump of coal in the night sky.
She said: & # 39; NEO & # 39; s are intrinsically weak because they are usually very small and far from us in space.
& # 39; Add to that the fact that some of them are as dark as printer toner, and trying to spot them against the black of the room is very difficult. & # 39;
Dr. Amy Mainzer said that trying to spot asteroids through their & # 39; vague & # 39; light, was like they were trying a & lump of coal in the sky of the night & # 39; but a proposed Near-Earth Object Camera (NEOCam) mission (photo) detects heat waves would make it a lot more accurate
The new camera, proposed to NASA, would use the latest camera technology to give astronomers enough time to intercept asteroids and comets on a course for Earth.
This is after NASA SpaceX from Elon Musk awarded a £ 52.7m ($ 69m) contract to launch a spacecraft to study whether asteroids can be rammed on a collision course with the Earth.
Dr. Mainzer said: & # 39; We are proposing to NASA a new telescope, the NEOCam, to do a much more extensive work of mapping asteroid locations and measuring their dimensions.
& # 39; If we find an object only a few days after impact, it greatly limits our choices, so in our search efforts we focused on finding NEO's when they are further away from the earth, the offer a maximum amount of time and open up a wider range of mitigation options for a wider audience.
Dr. Mainzer has proposed a new NEOCam telescope to NASA, which, in its view, could prevent similar stones against the dinosaurs from becoming future risks to the Earth. The image shown is a collection of images of the asteroid 2305 King by the spacecraft WISE
Their findings from the Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) telescope are crucial for setting up a defense strategy against asteroids that threaten the Earth.
This naturally includes ramming them – but the method needs details about the size and composition of the asteroid to calculate the mass.
Dr. Mainzer added a new telescope that can also be used to study ancient comets and asteroids.
She said: & # 39; With the NEOWISE mission, we can spot objects regardless of their surface color and use them to measure their dimensions and other surface properties.
& # 39; These objects are intrinsically interesting because some are supposed to be as old as the original material that made up the solar system.
& # 39; One of the things we have discovered is that NEO & s are quite diverse in composition. & # 39;
She said she now wanted to use the advancements in camera technology to help with the search for NEO's.
Dr. Mainzer is the principal investigator of NASA's asteroid hunting mission at the Jet Propulsion Laboratory in Pasadena, California.
She would present her plans to build a new telescope, the Near-Earth Object Camera (NEOCam) for this month's American Physical Society meeting in Denver, USA.

WHAT IS THE CHELYABINSK METEOR STRIKE?
A meteor that burned over the southern Ural Mountains in February 2013 was the largest recorded meteor storm in more than a century, after the Tunguska event in 1908.
More than 1,600 people were injured by the shockwave of the explosion, estimated to be as strong as 20 Hiroshima atomic bombs, when it landed near the city of Chelyabinsk.
The fireball measures 18 meters wide and screamed in the atmosphere of the earth at 41,600 mph.
A large part of the meteor landed in a local lake called Chebarkul.
Unlike the last find, scientists have already discovered more than 12 pieces from Lake Chebarkul since the February 15 incident. Only five of them turned out to be real.
What did they find in the meteorites?
Analysis of recovered Chelyabinsk meteorites revealed an unusual form of jadeite buried in glassy materials known as shock veins, which form after rock crashes, melts and solidifies again.
By calculating the speed at which the jadeite must have solidified, the team was able to determine that the asteroid formed after a collision.
Jadeite, one of the minerals in the gem jade, only forms under extreme pressure and high temperatures.
The shape of jadeite found in the meteorites of Chelyabinsk indicates that the parent body of the asteroid struck another asteroid that was at least 150 meters (490 feet) in diameter.
