Makes me think the Soviets may have been correct in their obsession over Venus, if only by sheer luck.

- Animats 2y agoVenus needs more attention. Mars is boring. Luna is boring. Venus might have some action. And what about Europa?
- bloopernova 2y agoEuropa is orbiting Jupiter. Jupiter puts out a lot of radiation: https://news.ycombinator.com/item?id=40978670 https://news.ycombinator.com/item?id=40978670 For sure, Venus needs exploration. I'd like to see an orbiting station with a 10 year mission to explore the Venusian atmosphere via drones or other methods.
- marcusverus 2y agoAny Europan life would be in its oceans, which are more than adequately shielded from radiation by a miles-thick layer of ice. https://en.wikipedia.org/wiki/Europa_(moon)#Subsurface_ocean https://en.wikipedia.org/wiki/Europa_(moon)#Subsurface_ocean

- ccakes 2y agoVenus definitely needs more attention but regarding outer solar system, my money is on Enceladus being the most interesting one
- idlewords 2y agoEnceladus is the new Europa!
- mcswell 2y agoAnd Enceladus doesn't have a no trespassing sign.
- moffkalast 2y agoMars is doable. Luna is convenient. Venus is pure acid under ridiculous pressure that melts any probe in minutes. Europa is too far for anything serious. Enceladus is even further away.
- c_o_n_v_e_x 2y ago>Venus is pure acid under ridiculous pressure that melts any probe in minutes. Only at the surface.
- nickserv 2y agoA balloon inflated at 1 bar would float around quite nicely in the venusian atmosphere.
- moffkalast 2y agoIt's an interesting concept to be sure, but is it technically feasible to make it reliable enough? The transition from orbital velocity, to atmospheric entry and blimp deployment sounds like it would involve significant stresses, and that's after being in space for half a year to even get there. One small micrometeorite and you have a leaky envelope and the mission is over. I think there was a proposal for a solar powered winged probe which although less cool, would be probably more likely to succeed.
- nickserv 2y agoSome of the earlier Mars rovers used inflatable balloons to cushion the landing. They bounced around for dozens of meters on rocks without popping. Not an expert by any means, but would think it should be possible to inflate a gas bag at a certain altitude, after dumping the thermal shield and using a parachute to slow down. A powered-flight probe would be interesting in that it could be more easily directed to specific areas and have the ability to stay over a given area. A balloon would likely not be as controllable. But would be happy with any Venus mission, even a low altitude orbiter would be cool.
