What could be the water pressure under the ice of Europe moon?
Could it be toleratable for not super expensive machines, structures?

Manned submarines that dove to Titanic were under 20 t. Unmanned submarines even lighter, but could not find numbers.stefan r said:0.134g. A vessel should be able to go 7.5 times as deep. A Los Angeles class submarine uses 'bout 290 meters, Some on Europa it could sink to 2,160m. I believe they are capable of more than the official operating depths.
You need a rocket that can launch a 6000 ton payload to Jupiter.
At the temperatures of Europa, yes, mechanical breaking would take complex and irreplaceable moving parts.SimplePrimate said:I guess there's the small matter of breaking through the ice

How about thermal breaking - a submarine that, for a test, dives through Antarctic ice sheet to Lake Vostok, and then to Europa? How conductive of heat is ice at -60 Celsius or under -100, and how much thermal power output (electrical power is not required for that purpose!) does a submarine 1 m across need to keep its surface just above 0 Celsius inside ice at -100 Celsius?
The pressure under the ice of Europa is estimated to be around 100 megapascals, which is equivalent to about 1000 times the atmospheric pressure on Earth.
The high pressure under the ice of Europa makes it unlikely for complex life forms to exist. However, some scientists believe that microbial life may still be able to survive in these extreme conditions.
The ice on Europa is primarily made up of water, but it also contains other elements such as sulfur and magnesium salts. This composition is similar to the ice on Earth, but with higher concentrations of these elements due to Europa's unique environment.
The pressure under the ice of Europa varies across its surface, with the highest pressures found near the equator and the lowest pressures near the poles. This is due to the varying thickness of the ice crust and the gravitational pull of Jupiter.
Scientists use remote sensing techniques such as radar and infrared imaging to measure the thickness of the ice crust on Europa, which can then be used to estimate the pressure underneath. Future missions to Europa may also include instruments specifically designed to measure pressure and other environmental factors directly.
