NASA Keeps An Eye On Some Space Junk

Posted by 3citynewswire on 06/18/2010

CAPE CANAVERAL, Fla. (June 18, 2010)–NASA is keeping a close watch on three pieces of old Russian and Chinese satellite and rocket parts that could come uncomfortably close to the International Space Station this weekend.

Mission managers decided there was no need to move the station Friday to dodge a fourth piece of junk, but the station’s orbit continues to be reassessed.

A Russian capsule docked Thursday carrying three new residents.

The Soyuz arrival means there are now two women living full time at the space station for the first time ever.

Shannon Walker, a physicist from Houston, joins Tracy Dyson Caldwell. Walker took Amelia Earhart’s watch into orbit.

Four men also are on board the space station.

Space Station to Receive New Anti-Matter Detector Component

Posted by 3citynewswire on 04/28/2010

Scientist plan on replacing the liquid helium cooled magnet, in the anti-matter detector, with an Alpha Magnetic Spectrometer. This will increase the life span of the detector from 3 years to about 18 years.

The AMS (anti-matter spectrometer) is designed to search for anti-matter particles as well as perform other experiments. The device is equipped with over 300,000 data channels that require compression with an on-board supercomputer before the information can be transmitted to Earth.

AMS functions by sampling high-energy particles from deep space. The sensitivity of the AMS is more than 100 to 1,000 times more sensitive than previous instruments.

Samuel Ting of MIT is overseeing a 500 member global team of scientist to work on this 1.5 billion dollar project. This was made possible because US President Barack Obama has proposed to extend the space station for a minimum of 5 years beyond 2015, with an additional budget of 3 billion dollars per year.

In an interview Ting stated: “This really is the very first very, very precise particle physics detector. You enter into a totally new domain. It’s very hard to predict what you’ll find.”

The AMS is a prototype that flew on a 1998 space shuttle mission and was recently taken out of a clean room storage facility in Germany. By replacing the liquid helium cooled magnet with the AMS cuts the power of the magnetic field that is used bend the path of charged cosmic particles while they pass through various detectors.

Ting is optimistic that having the less powerful AMS in orbit the extra years would more than compensate for the liquid helium cooled magnet. There are also spares on hand if it ever requires replacement.
