Humans have sent space missions to Venus since the 1960s, though many early attempts ended in failure.
The first successful flyby of Venus was performed by Mariner 2 in 1962, with the first successful atmospheric entry by Venera 4 in 1967. Later missions successfully soft landed on Venus, providing us with a view of the planet's surface.

Tell us about going to Venus… What makes it so hard?
