Mercury and Venus

Mercury

Venus

To date only two satellites have visited Mercury.
Mariner 10 and Messenger. Scheduled to launch later in 2018 is BepiColombo. No human travel to Mercury exists yet...

Venus has had numerous satellites fly by and study it. Only the Venera probes have landed on
The hot, thick surface.

Factoid:
Due to the extreme pressure and temperature of the surface of Venus any human visitation or settlement would be in the upper atmosphere. Floating cloud "cities" are a possibility.
