It appears that sensors on board the International Space Station, designed to measure ozone particles and aerosols in the Earth 's atmosphere, have detected alarming levels of chemicals.
Do spatial bacteria turn into a strain threatening the health of pioneers?
These increases were related to the charge of Space X Dragon capsules, where it is thought that the problem is causing this problem, prompting the NASA US space agency to investigate this contamination.
The SAGE III sensor, launched in February 2017, recorded unexplained levels of pollution when the Dragon capsule was attached to the ISS.
The molecules were released by the capsule in a reaction known as gas release, causing them to adhere to "SAGE III".
This phenomenon occurs when the molecules trapped in the material are released, the process behind "the smell of the new car" in any vehicle.
In space, this process can be very destructive and, in the ISS, it can affect the exact measurements taken. It can also create a greasy layer that can cause disasters aboard the space station.
To solve this problem, most space devices are built in a clean room, so that they are "cooked" to remove contaminants.

NASA was at first disconcerted by the rising level of pollution recorded, and was warned in a report issued by the agency's management that "the external load is a source of pollution".
