Traces of plankton and other microorganisms had been found living on the exterior of the International Space Station ISS, according to Russian Space Officials. They claimed the plankton were not carried there at launch, but are thought to have been blown there by air currents on Earth. Incredibly, the tiny organisms were found to be able to survive in the vacuum of space despite the freezing temperatures, lack of oxygen and cosmic radiation. The discovery was made during a routine spacewalk by Russian cosmonauts, all like our team of an Alexander Scvortsov, who were launching the NASA lights into space. They used wipes to polish the surface of windows, also known as illuminators, on the Russian segment of the ISS and later found the presence of plankton and other microorganisms using high precision equipment. The results of the experiment are absolutely unique, said the head of the Russian ISS Orbital Mission Vladimir.
