Isn't the dv/dt really the issue? If Venus has stable high altitude wind, would the speed really matter?

- klyrs 6y agoCall me pessimistic but I'd expect some pretty wicked turbulence... what'll happen to that blimp when each side is taking on cat5 velocities in different directions? "Artificial gravity" is not the right answer ;)
- omgwtfbyobbq 6y agoThat doesn't seem to be the case for the most part, although I'm sure something would need to consistently monitor weather conditions to avoid anything close to that. This altitude is within the high-velocity "superrotation" region of the Venus atmosphere, where a constant wind moves at a velocity on the order of a hundred meters per second. This means that over the two days of the mission, the balloons traversed about 11,000 km, from the night hemisphere into the day hemisphere. About two days into the mission, the primary batteries were depleted, and contact was lost. https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20110016033.pdf https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/201100... Edit - According to this the zonal winds are ~60mph at certain elevations. https://trs.jpl.nasa.gov/bitstream/handle/2014/44535/13-5079A1b.pdf?sequence=1 https://trs.jpl.nasa.gov/bitstream/handle/2014/44535/13-5079...
