Why in news?

Researchers at the Massachusetts Institute of Technology in a new study finds that Climate change will soon be making a mess in orbit around the planet.

  • Global Warming – Burning of coal, oil and gas reduce the space available for satellites in the Low Earth orbit (LEO).
  • By the end of the century almost 82% of the space will be reduced because of carbon emissions.
  • Greenhouse Effect – Along with warming of air near earth’s surface it simultaneously cools the upper parts of the atmosphere.
  • This makes the upper atmosphere less dense which reduces the drags of the debris present.
  • Atmospheric DragKnown as Air resistance, this drag pulls the space junks down to the earth by burning it.
  • But having reduced drag effect makes less space cleaning making the atmosphere more crowded with satellites and space debris.
  • Natural cleaner – Atmosphere is the natural cleaner to clean up the debris as there is no other way as there are million pieces of it.
  • Circling Trash – According to the Aerospace Corporation, circling earth is home to millions of space debris which travels at the speed of a bullet and has the power of a crashing bus.
  • Satellites Records - According to the tracking website orbit.ing-now.com, there are 11,905 satellites circling Earth, 7,356 in the LEO.
  • Decreasing Density - The density at 250 miles (400 kilometers) above Earth is decreasing by about 2% a decade and is likely to get intensify because of the Greenhouse Gas Effect, according to British Antarctic Survey.
  • NASA Records – Shows that there is measurable reduction of drag, realizing climate change component is really important.
