1. Space debris

   Space debris, also known as orbital debris, space junk, and space waste, is the collection of defunct objects in orbit around Earth. This includes everything from spent rocket stages, old satellites, fragments from disintegration, erosion, and collisions. Since orbits overlap with new spacecraft, debris may collide with operational spacecraft. Currently about 19,000 pieces of debris larger than 5 cm are tracked, with another 300,000 pieces smaller than 1 cm below 2000 km altitude. For comparison, ISS orbits in the 300–400 km range and both the 2009 collision and 2007 antisat test events occurred at between 800–900 km. Most space debris is less than 1 cm, including dust from solid rocket motors, surface degradation products such as paint flakes, and coolant released by RORSAT nuclear-powered satellites. Impacts of these particles cause erosive damage, similar to sandblasting. Damage can be reduced with "Whipple shield", which, for example, protects some parts of the International Space Station. However, not all parts of a spacecraft may be protected in this manner, e.g. solar panels and optical devices, and these components are subject to constant wear by debris and micrometeoroids. The flux of space debris is greater than meteroids below 2000 km altitude for most sizes circa 2012.

   There's a real need for us here on Earth who don't work in the space industry to begin to understand how space debris impacts us every day, many of us don't realize how much of our lives are reliant on services delivered from and through space — GPS services, financial transactions, climate monitoring. Our life on Earth is connected to space and even the smallest debris orbiting the Earth can damage and destroy these critical capabilities for some of the most basic aspects of our day-to-day life.
