Submarine to Titan's methane to be tested in an artificial sea
NASA engineers and the University of Washington are working together to develop a submarine capable to help scientists study the sea of Titan, Saturn's moon. A few years ago, the "alien submarine" was only a concept, but now developers are already conducting trials of its early prototype and even pose for these purposes, an artificial sea of methane and ethane.
On Titan, there are many rivers, lakes and seas, consisting of methane. On Earth, it is present in the gaseous state, but on Titan is very different conditions, and the temperature is too far removed from our own, so there is liquid methane, and this means that it is possible to swim, spending in this study. Pressure and low temperatures, as well as other unpleasant nuances that can significantly hamper the process of investigation, photo and video shooting, so now scientists are trying to solve the problem. The recent testing of a special camera and borescope tested positive, which is very encouraging.
NASA plans to send a submarine to Titan in the coming 20 years, and while testing its prototype artificial "sea" of methane and ethane, in which the temperature is - 180 degrees Celsius. The submarine, on which scientists are working, will operate autonomously, collecting data on oceanic and atmospheric conditions of Titan.
