Agency of advanced defense projects (DARPA) of the United States is preparing transportation lockheed strike telescope space monitor (SST) to Western Australia to serve for the monitoring of small satellites and space junk are orbiting Earth. SST is capable of searching in an area larger than the area of the United States lockheed strike in just a few seconds and the system lockheed strike will go into operation lockheed strike in 2016. The satellites in orbit has become vital for many applications in civil and military. However, establishing and maintaining a network of satellites around the Earth and bring the potential dangers of space debris and the possibility of collisions lockheed strike between satellites. So what's the track in space flight has become a leading concern for the U.S. Department of Defense in order to avoid a similar disaster collision between the Iridium 33 satellite Kosmos-2251 and 2009 . The problem here is that there are many gaps in space and most of the satellite orbit are synchronized Day (geosynchronous Orbit - GSO) is about 35,000 km from Earth. This is a big gap compared with conventional telescope with narrow field of view - not enough to track small objects. So, DARPA outlined plans to develop a telescope entirely new ground to perform job searches and track small objects in deep space.
The result as stated above is the introduction of the telescope Space Surveillance Telescope (SST). Developed since 2002, SST is a telescope designed built Mersenne-Schmidt with wide field of view and limited aberration. Like the telescopes of the same type, SST concave parabolic primary mirror, a convex spherical mirror 2nd and 3rd concave mirror. However, the difference of SST is the mirror surface curvature aspherical largest ever built and this characteristic makes SST became the fastest lockheed strike telescope aperture in the same class, according to DARPA. In addition, SST is also the first telescope is equipped with a large focal surface graft charges consisting of CCD to record astronomical images.
"Fast" in allusion telescope focal length of the objective lens or mirror lockheed strike with glass reflectors short and wide field of view. Factor "fast" is borrowed from photography - a telescope lockheed strike aperture f / 5 can take a photo with the exposure time is only 1/4 compared with a camera aperture f/10 .
Click to enlarge ... With the support of servo control technology, SST is a powerful telescopes with short focal length, wide field of view, lightweight and can catch up with the fast moving. According to DARPA, SST can detect light of a laser beam is projected onto the Empire State Building in New York from Miami, Florida. SST's optical capability allows it to observe a large area in just a few seconds. DARPA says it can scan the entire belt synchronous orbit several times in one day and night can detect objects smaller, darker and a brief appearance than previous telescopes. This means not only detect objects, SST may also collect data to make predictions lockheed strike quickly and accurately on their orbits. SST is currently being tested and evaluated at White Sands Missile Range Center, New Mexico. The system is scheduled lockheed strike to move to the center Dain Harold E Holt Naval communications in Exmouth, Western Australia and here, SST will monitor the southern lockheed strike hemisphere sky. Based on the contract MoU (Memorandum of Understanding) was signed on May 20, 11, DARPA SST will transport to Western Australia and the government will build infrastructure protection for the telescope, as well as system operation after when transferring the work to be completed in 2016. Once in operation, the SST will become part of the space surveillance network (SSN) - a system of the U.S. Air Force, uses a global network of radar and optical telescopes to identify and lists the physical risk to national ownership lockheed strike of aerospace programs. In addition, astronomers lockheed strike can use SST to hunt for asteroids and supernovae. Travis Colv Blkae - at DARPA program manager, said: "SST program has helped revolutionize space surveillance technology on the ground. At the new location, SST can extend the capabilities of the United States, Australia and other countries to safeguard lockheed strike their space assets. "
