Quote:OSIRIS-REx will be launched in September 2016, and will encounter the asteroid in 2018. It will then study the asteroid for about 6 months, globally mapping the surface from a distance of 7 km down to 250 m. The sample will be returned to Earth in 2023.

Quote:The target asteroid, Near-Earth Object (NEO 101955) 1999 RQ36, is an exciting and accessible volatile and organic-rich remnant from the early Solar System, as well as one of the most potentially hazardous asteroids known to humanity. Observations using telescopes have revealed that 1999 RQ36 is very dark. Scientists have classified it as a B-type asteroid, a rare subgroup of the dark, carbonaceous C-type asteroids. These asteroids are considered to be primitive objects, having changed little from their time of formation.

Well at least they are trying to doing something to protect the Earth from these dangerous asteroids. By bringing home a sample of the asteroid, they can then determine which measures should be used for deflection, or blowing it up, or hopefully in 10 years there will be new technology available.

Asteroid 1999 RQ36 likely to hit the Earth in 2182:

Yes, they are looking to the far future for solutions that may save us from possible extinction. Now if only they would take a stab at looking ahead in regards to environmental and societal issues. This study may all be in vain.

from conversations around me ,,,

and a parking cop sitting behind me with her radio on ,, and what i am hearing
from it ,,,

extinction is quite possible , and it won't require any off World objects chuckle.gif

A new study suggests volcanic activity is to be blamed for the last mass extinction. So, we've got potential mass extinction threats coming from all directions.

Quote:The deadly ancient volcanoes weren't mountains. Rather, they were long, magma-spewing fissures in the Earth, similar to the Krafla eruptions in Iceland, but "much, much bigger," McHone said.

I read this just today:

Four asteroids flash past Earth in one day

Quote:Earth is experiencing an unusual cosmic bombardment as four large asteroids pass it in just one day. Fortunately astronomers don't seem to joking when saying none are expected to pose danger.

The largest is 4034 Vishnu, which is 800 meters across - the length of the Burj Khalifa in Dubai - though much greater in mass. In comparison, the Tunguska meteorite that devastated hundreds of miles of Siberian wilderness when it landed in 1908 was estimated to be no bigger than 100 meters. The asteroid that may have led to the extinction of dinosaurs 65 million years ago may have been up to 10 kilometers across.

But 4034 Vishnu - which was discovered in 1986 - will pass nearly 23 million kilometers from the Earth's surface. The closest of the four, EN 89, will be just over 5 million kilometers away from the planet. The asteroid was only discovered a fortnight ago.

Also think this might be a reason they're interested in studying these space rocks:

Quote:Earlier this year, Astrorank, a company that evaluates the make-up of asteroids in view of future space mining operations, said that 4034 Vishnu - which is composed largely of platinum and nickel-iron - is worth around $40 trillion dollars, more than half of the world's gross national product last year.

Yes, I read studies where the scientists are saying that most of the asteroids are too small, or are composed of materials that will explode/dissintegrate within our atmosphere, so nothing to worry about folks...move along.

Wouldn't it just be easier to mine the moon?

Easier probably, but perhaps the moon doesn't contain any valuables. dunno.gif

From this article, it seems the moon is worthless in mineral resources.

So, then we turn our eyes to diamond asteroids. Why do all the 'good' asteroids end up in Russia?

The moon has Helium-3.
Quote:Helium-3 is proposed as a second-generation fuel for nuclear fusion in hypothetical fusion power plants, but such plants are still very early in their development—especially since first generation reactors have not yet entered into service. Helium-3 can be used in instruments for the detection of free neutrons, such as neutrons leaking from nuclear reactors.

Still, my money is on Thorium for ease of access and abundance. http://www.telegraph.co.uk/finance/comme...orium.html

They just won't let the 'catch an asteroid in a bag' idea go - but this time it's a draw-string bag. chuckle.gif
