ISS Filling With Fungi And Bacteria That Can Decay Spacecraft

The ISS (International Space Station) is brimming with fungi and bacteria that can form biofilms and lead to diseases that promote antibiotic confrontation, and can even decay the spacecraft, a new research has discovered.

The station, developed in 1998 and revolving above the Earth around 250 Miles, has been seen by over 222 astronomers and almost 6 resupply missions annually till August 2017. NASA researchers found microbes majorly arriving from humans and were same to those seen in public offices and buildings here on land. The research—the first to offer a complete catalogue of the fungi and bacteria lurking on inner surfaces in closed systems—was posted in the Microbiome journal.

One of the authors of the study and a senior research scientist at the NASA Jet Propulsion Laboratory, Dr Kasthuri Venkateswaran, claimed: “The ISS is a hermetically preserved closed system, subjected to radiation, microgravity, the recirculation of air via HEPA filters, and increased carbon dioxide, and is believed as an ‘extreme environment’.” He claimed that microbes are believed to survive and even flourish in extreme cases.

On a related note, almost after 6 Years in space, the first orbital station by China, the Tiangong-1 (also dubbed as the “Heavenly Palace”) has lastly outlived its working restrictions and started its journey to Earth. In a few months, it is anticipated to re-enter the atmosphere whereupon a bulk of the 9.3-ton station must burn up prior to reaching the land. This is how obsolete satellites are supposed to be getting rid of. Unluckily, until very lately, that has not often been the situation.

For the last 5 Decades, we have been crowding the Low Earth Orbit with obsolete upper stages of launch vehicle, satellites, and different bits of broken spacecraft (comprising coolant, frozen water, and paint flecks).
