Venus will be the 3Dimensional spaceport for the entire Solar System within 2-3 decades.
Think! Coming in from a mission to Jupiter's Moons on an express path and entering Earth's atmosphere? You'd burn to a crisp!
Now, gently enter Venus' gravity well and gradually use its thick clouds for aerobraking you could slow to a convenient Venusian orbital pattern or boost to an Earth rendezvous orbit.
What all this means is that Venus WILL be the 'entry-port' for this entire Solar System, Just like JFK is for the entire USA.
Venus has a BIG future in this human-dominated Solar System and eventually, all this activity will render Venus' cloud layers 'Earth-quality' habitable.
