The increasing population of space junk raises the potential risk to all space machinery, especially to the space shuttles, International Space Station and any other spacecraft with humans aboard.
NASA considers the threat of collisions with space junk seriously and has a long-term set of guidelines on how to handle each potential threat.
A new report warns that there is excess s debris in space which collisions could begin to increase exponentially, leading to constantly growing a pile of rubble in orbit.
The Independent report, released on September 1, 2011, surveyed NASA’s effort to meet the threat of space junk. It was sponsored by Nyasaland carried out by the National Research Council, a non-profit science policy organization.
The report highlighted the necessity for NASA to lead the gathering of urgently necessary data in many areas to boost scientific models and the predictions of the effect of space debris collisions.
For instance, the committee recommended that NASA should study the difference in how different types of spacecraft act and break up during a collision.
Though the outer space is usually imagined to be an empty and desolate place, the region around our planet swarms with several pieces of artificial debris. They create potential hazards for their functioning neighbors. Space junk is the biggest problem in the universe. Some of them are gigantic, such as dead spacecraft, burnt-out rocket stages, and a few tools lost during spacewalks. Nevertheless, most of them are very small. Where did all of this space junk come from? Will it ever go away? What kind of dangers might it create to people living on Earth? Let’s explore some facts here!
Interesting facts about Space Junk and Debris:
1. Space satellites are typically launched by governments as well as companies and individuals. For example, if you have a cell phone, it operates due to satellites launched by your phone’s company.
2. In 2012, Russia had 1446 various satellites in orbit over the Earth; The United States had 1111.As of 2010, about 8,000 artificial objects were orbiting the Earth.
3. Space junk can pose grave dangers. Working satellites can accidentally crash into the space junk, creating additional space junk. Sometimes space junks fall back to our Planet. Most of the time, it touches the Earth surface. Not always!
4. Scientists are trying to come up with the ways of cleaning up space junk.
5. Satellites are over-priced. It costs approximately $100 million to build them and additional $50 million to launch them.
6. NASA was the first space agency to offer guidelines for orbital debris mitigation in 1995.
