ESA's mission to explore Jupiter and its icy moons called JUICE just passed the Key Decision Point C approval from NASA. This means the mission is now out of the design phase and will now move to the building stage.
NASA's Europa mission is moving to the second phase. Phase B is the design stage where the draft of systems and subsystems will be created before fabrication and testing in phase C and D.
In hopes of understanding the marine environments of the Earth, scientists make use of underwater drones. This same method is also being used by scientists working at NASA, but the difference is that they are developing an “intelligent” kind which would help them study Jupiter’s moon, Europa.
