Space is completely filled with all kind of space garbages which even include the kinds of stuff humans keep on sending with good intentions can cause problems. The small satellites named CubeSats, which are lesser than three pounds in weight were first sent into space December 2006. It gained popularity as it's a cost-effective choice for telecom companies which needs spreading WiFi and goodwill.

The problems which experts are very much concerned are there are chances for them bashing into each other and even worse probabilities. Recently at the European Space Agency's conference on space wreckage in Darmstadt, Germany, a senior lecturer in Aerospace Engineering at the University of Southampton, Hugh Lewis explained how tragic it could be for satellites should if CubeSats crashes each other. In the disastrous case, this could be a collisional avalanche named Kessler Syndrome, which signifies a horrible cloud of space garbage that would make the remarkable risk to proper spacecraft, which includes ISS.

 According to New Scientist, Lewis, and his team have used a supercomputer to simulate 200 years of possible orbits for 300 different mega constellation scenarios or sprawling networks of CubeSats ie small satellites. Allegedly, these endless networks of small satellites boost the hazards of a disastrous crash which may lead to the destruction of satellites by 50 percentage.

Beneficially, the ESA too released a documentary on recent space garbages, projecting the hazard posed by not only CubeSats but also hundreds of thousands of tiny space garbages floating around Earth's backyard other than small satellites. Lewis and his buddy researchers have suggested space agencies like the ESA to get back inactive satellites as soon as possible to control the space junk situation from running out of control. They also have encouraged redesigning small satellites so they can steer clear of objects and suicide plunge into Earth's orbit once their lifespan has ended.
