why dont they send a probe to scoop up some venus air and bring it back? seems much easier than going with humans around the moon
Well, there's the scenario where a Venusian superbug, having evolved in the roughest possible conditions (temp, acidity, etc...) in the upper Venusian atmosphere, will find Earth's conditions warm, balmy, and altogether ideal to reproduce at 1000x the rate it was constrained to back home :D
Better, why don't they do some sort of "ocean fertilization" experiment on Venus cloud decks. Putative life high on Venus atmosphere must be limited by low levels of minerals. Sending a probe with a few tons of salts to disperse in a cloud patch should be enough to produce a local equivalent to an algal bloom, detectable through imaging from orbit.
"The probe's cargo vessel has a really awesome ablative heat shield on it, as well as some extremely reliable parachutes, and Mission Control is projecting a very soft touchdown in the Utah desert within the next 12 hours. If anyone in the Western United States sees a huge fireball going slower than most meteors, it is probably the Venus Sample Return vessel full of dangerous chemicals! Go VSRM!"
