Abstract:                                                                                                                 
Venus is an extremely difficult target to study, but worth the effort. The tesserae, the highly tectonized and ancient highlands of Venus, will help constrain the conditions necessary for plate tectonics and habitability, as well as answer dozens of other long standing (and some new) scientific questions. But, they aren’t easy to get to. Our highest resolution imagery and topography are ~100 m/pixel and ~1-2 km/pixel; the surface boils at ~840F; and the surface is obscured by the cloud deck and atmospheric Rayleigh scattering until within a few kilometers of the tesserae. In this talk, we’ll discuss why we need to visit the tesserae, the hurdles we have to cross, and some of the ways in which landers and unmanned aerial vehicles will cross those hurdles and get the data that we need.
