However, modern satellites are designed to break up into smaller pieces upon reentry, so less material makes it to the surface. The U.S. Air Force sent the first GPS satellite into orbit in 1978, and many other launches followed over the years. However, removing space debris from LEO is logistically challenging and there is still no agreed upon method of removal, according to Scientific American (opens in new tab). In, JSR. Once launched, GPS satellites do not change their plane assignment but slot assignments are somewhat arbitrary and are subject to change. The worst known space collision in history took place in February 2009 when the U.S. telecommunication satellite Iridium 33 and Russia's defunct military satellite Kosmos-2251 crashed at the altitude of 490 miles (789 kilometres).
