Space.com’s Leonard David reports that NASA and ESA planetary scientists are working out the details on possible flagship-class missions to Jupiter and Saturn that include landers, balloons and a mini-submarine.
“We have the outer planet flagship mission in the [NASA] budget … I do believe it will happen,” said Dr. Fran Bagenal, who heads up the chair of the Outer Planets Assessment Group (OPAG). “I couldn’t have said that four years ago … now I have great confidence that this will happen.”
One mission under review involves two orbiters to study Jupiter and its frozen moon Europa, which scientists believe possesses a subsurface ocean. Russia has proposed a Europa lander for the flight.
The Saturn mission would involve a main spacecraft that would orbit the gas giant and a smaller one to explore its satellite Titan. The Titan vehicle could deploy an atmospheric balloon, surface probes, or a mini-submarine to explore the moon’s methane lakes.
