The Debris Field You Don’t Hear About
Posted in: Out of this World | Comments (0)
A report by the National Research Council says the debris could cause fatal leaks in spaceships or destroy valuable satellites.
It calls for international regulations to limit the junk and more research into the possible use of launching large magnetic nets or giant umbrellas.
The debris includes clouds of minuscule fragments, old boosters and satellites.
Some computer models show the amount of orbital rubbish “has reached a tipping point, with enough currently in orbit to continually collide and create even more debris, raising the risk of spacecraft failures,” the research council said in a statement on Thursday.
Situation ‘critical’
Hopes of limiting the amount of space junk in orbit suffered two major setbacks in recent years.

There are lots of ideas out there to clean up space. Many of them, I have to say, look far-fetched and utterly impractical”

In 2007, China conducted an anti-satellite weapon test which destroyed a decommissioned weather satellite, smashing the object into 150,000 pieces larger than 1cm.
Two years later, two satellites – one defunct and one active – crashed in orbit, creating even more debris.
“Those two single events doubled the amount of fragments in Earth orbit and completely wiped out what we had done in the last 25 years,” said Donald Kessler, who led the research.
There are 22,000 pieces of debris large enough to track from the ground, but smaller objects could still cause serious damage.
The International Space Station must occasionally dodge some of the junk, which flies around the Earth at speeds of up to 17,500 mph (28,164 km/h).
Dr Robert Massey, Royal Astronomical Society: “It is a serious issue”
In June, some debris narrowly missed the space station, forcing its six crew to go to their escape capsules and prepare for an emergency evacuation back to Earth.
The situation is critical, said Mr Kessler, a retired Nasa scientist, because colliding debris creates even more of the junk.
“We’ve lost control of the environment,” he said.
The report makes no recommendations about how to clean up the field of debris.
But it refers to an earlier study for the Pentagon’s science think-tank, the Defence Advanced Research Projects Agency (Darpa).
The Darpa report, dubbed “Catcher’s Mitt”, suggested a range of technologies, including harpoons, nets and an umbrella-shaped device that would sweep up the debris.
The aim would be to push the debris further towards the earth where it would burn up, or into a higher but safer orbit.

This is amazing and somewhat scarey Put your mouse on the orange dotts.
Check out this website. It’s amazing how the pacific rim is still just shaking every hour of the day!

Update Article: (From UFO Blogger) http://www.ufo-blogger.com/2011/08/starchild-skull-shocking-dna-results.html
Preliminary new DNA results from the 900 year old Starchild Skull, providing information that a percentage of the DNA in the bone may not be from Earth.

The starchild skull came into the possession of Lloyd Pye in February 1999 , the skull was found around 1930 in a mine tunnel about 100 miles (160 km) southwest of Chihuahua, Mexico, buried alongside a normal human skeleton that was exposed and lying supine on the surface of the tunnel.
radiocarbon dating results conclude the skull is 900 years old + or – 40 years
