The sign by the Mariner 2 replica. It reads.

First Spacecraft to Study Another Planet

On December 14, 1962, Mariner 2 passed within 34,800 kilometers (21,600 miles) of Venus. The 109-day flight covered a distance of 58 million kilometers (36 million miles). For the first time, useful scientific information was radioed to Earth from the vicinity of another planet. Mariner 2 indicated that Venus is very hot, perhaps more than 427°C (800°F), and it has no measurable magnetic fields or radiation belts. Contact with Mariner 2 was lost on January 2, 1963; it is now in orbit around the Sun.
