Venus sample return mission

Venus is quite a forbidden planet: it has a surface atmospheric pressure of 9.3 MPa (93 bar), an atmospheric density of 67 kg/m3 and a surface temperature of 740 K.

If in a near future we will be able to build a rover for this prohibitive environment, we will probably also want to retrieve some sample.
Given we have found a way to store propellants at the right temperature, I suppose rockets would have a very poor performance at 9.3 MPa of ambient pressure (It's right, GW?).

So a good strategy might be to reach the upper atmosphere with a helium balloon, then fire the rocket.

Re: Venus sample return mission

For Quaoar,

There are 55 topics in this forum which contain the word Venus.

Of those, several are about missions to Venus, in addition to a possible Russian probe in 2024.   I presume you read ALL of those posts before starting a new topic about Venus.  You have chosen wording that is NOT an exact duplicate of the existing topics, but the similarity is so close it seems to me one of the existing topics would have been a good place to look to see if this topic has been discussed at great length previously. 

Now would be a good time for you to collect all the related posts and include them (by link of course, not the actual contents) in your new topic.
