There are plans in the works for a sample return mission from Mars in the next 10 to 15 years.
No mission has ever returned anything outside of lunar orbit.
Venus would be verry difficult for anything but upper atmosphere. Probes don't last above a few minutes with pressures 10 to 50 times that of earth, tempatures on the surface aloow for molten rock on much of the surface and sulpheric acid for rain.
Can we get a decision?
