With aerobraking it's much easier to get to Venus, though, and every landing we've ever done on Mars or Venus has made heavy use of Aerobraking.

- Symmetry 7y agoHow so? If you do an aerocapture to descent the way we normally land planetary probes it's 3850 m/s of delta-v from LEO to Venus intersect but 4270 m/s for Mars. We don't have as good a sense for the atmosphere on Venus as on Mars so I assume you wouldn't have the same prevision in landing on Venus as Mars doing things this way but for a blimp that doesn't really matter. Also, the Venus intersect will be at higher velocity so you'll need a heavier heat shield.
