He will be the last one laughing on Mars
Once his meds kick in he might be there before he is 30.
I don't take any meds and nor do I need any. I'm going to help create a spacefaring civilization by designing spacecraft which will use less fuel, be able to be converted into space stations (the massive helium reservoirs would be able to be converted into chambers and the ships themselves be building blocks to centrifugal stations).
How would you get them up there to begin with?
The lighter-than-air spacecraft would have their primary stage be ascension via buoyancy. Now, that in itself is not going into orbit, but merely gaining altitude. A valve system would be in place to have the helium reservoirs decrease in pressure with increasing altitude so that density remains a near constant. Once the maximum altitude through buoyancy has been reached, then conventional propulsion systems would be used to ascend into orbit. With increasing altitude there is less air density which will allow for a more efficient usage of fuel, also it means that the conventional propulsion would be used once a fair bit of potential energy is already imparted to the ship.
