Using diving technology to reach the surface of Venus

[zypofaeser]

Given that there has previously been concepts for missions to the upper atmosphere of Venus (NASAs HAVOC etc), I began to wonder if the technologies used for diving could solve some of the issues related to surface mission. Deep dives, both simulated and under water (https://www.newscientist.com/article/mg13618493-000-technology-dry-run-for-deepest-dive/ , https://en.wikipedia.org/wiki/Saturation_diving#Depth_records), have been conducted at depths with pressures higher than what can be found on the mountains of Venus (https://en.wikipedia.org/wiki/Maxwell_Montes), so is it possible that the first person to set foot on Venus, will do so while breathing Hydreliox?

Edit for clarification: This is mostly with the idea that you can avoid having to reinforce your habitat/space suit against the immense pressure of the atmosphere, instead allowing you to have the astronauts mainly focussing on keeping the heat out of the habitat. (On that note I wonder how the AC system is going to work  )

The surface temperature of Venus is 900 degrees Fahrenheit, which is hot enough to melt lead. Humans should just stay up in the clouds.

The thermal issues are a concern. But in terms of expeditions/planting flags you might have to have a dry ice cooled habitat/suit in order to "get the achievement".

The planned VERITAS mission will use high resolution to get a clearer view of the surface of Venus, even with high atmospheric pressure and heat enveloping the planet's surface.

OK... but you go first.

Solvable. Am reminded of the A12/ SR-71 cockpit air conditioning. Quote from Ben Rich’s book on ground testing, page 216 “The guy sat inside a cylinder cooled to 75F degrees by Ben’s air- conditioning system while the outer skin of the cylinder cooked at 600F degrees”

EDIT: Thinking about this more, Ben had the frigid air to play with and that most obvious heat sink does not exist readily on Venus. So more difficult than I thought initially.

Maybe, but the SR-71 wasn't sitting in an effectively infinite sink of 900F, 93 bar CO2.

Agreed, just realized that myself see edit.

The only realistic long term way of landing biological matter on Venus's  surface is to territory the atmosphere.

My first thought was, just dig down some to a nice cool depth away from the heat above.  Then with a bit of research on the idea learned that there is no cool depth underground on Venus.  It just gets even hotter as you go underground.  That makes the idea of human visitation to the surface of Venus not only really, really hard, but pointless without Terraforming first.  [deleted]
