I recently studied that life may exist on Europa, an icy moon of Jupiter.
Does NASA plan to land a spacecraft on Europa to study its environment in the near future?
"Plan" is a vague word...
NASA has an orbiter mission in the works: Europa Clipper as a predicate mission prior to any attempt to land.
A Europa Lander is a "concept under study" - that is, they are making plans to do the project, but haven't budgeted for it, nor have then given the actual project the proverbial "green light." NASA does have a page about a Europa Lander
So, at present, they intend to do so eventually, but a specific mission is not yet in the works.
The entire purpose of the JUICE mission is to:
to characterise the conditions that may have led to the emergence of habitable environments among the Jovian icy satellites, with special emphasis on the three ocean-bearing worlds, Ganymede, Europa, and Callisto...
In addition to NASA's plans, a key figure pushing for Europa missions is Congressman Culberson, who is in line to become the next chairman of the House Appropriations subcommittee responsible for NASA’s budget.
The interesting part of Europa (its ocean) is buried under 30 km of ice. Getting to that ocean is a challenge we haven't solved on Earth, let alone halfway across the Solar system. So this is what's being worked on at the moment. Europa Clipper's results will help solve the challenge, it is hoped (it will look for vents where liquid water comes to the surface, for example). Once we have a feasible solution, it's time to start planning a lander mission.
