Russian scientists are developing automatic sealing systems to protect future manned space stations on the Moon and Mars from debris, Russia's Central Research Institute of Machine Building said.
"Protection of spacecraft modules against micrometeorite impact and space debris, based on the use of protective screens, that is passive protection, is at the limit of its technical capability due to weight restrictions," the institute's experts said.
"This is why we need to develop new protection based on self-sealing systems capable of independently and quickly restoring the object's air-tightness in case of leaks," they said.
Scientists said there are three ways of self-sealing a spacecraft. The first is to place a plug into the hole and thus stop the air leak. The second is to feed liquid sealant into the rupture, and the third is a combination of the two methods.

The solution to the Ukrainian problem will directly depend on how the military operations unfold in Donbass. If the militia fighters take over the strategic initiative, win back Donbass and extend the war to the Zaporozhye and the Kharkov regions, then Kiev will be more amenable to a compromise
