Russian Venus probe. The 1VA probe, the first spacecraft sent towards Venus, consisted of a cylindrical body topped by a dome, totaling 2 meters in height.

AKA: 1VA. Status: Operational 1961. First Launch: 1961-02-04. Last Launch: 1961-02-12. Number: 2 . Gross mass: 644 kg (1,419 lb).

Two solar panels extended radially from the cylinder. A large (over 2 meter diameter) high-gain net antenna was used to receive signals from the ground. This antenna was attached to the cylinder. A long antenna arm was used to transmit signals to Earth. The probe was equipped with scientific instruments including a magnetometer attached to the end of a 2 meter boom, ion traps, micrometeorite detectors, and cosmic radiation counters. The dome contained a pressurized sphere which carried a Soviet pennant and was designed to float on the putative Venus oceans after the intended Venus impact. Venera 1 had no on-board propulsion systems. Temperature control was achieved with thermal shutters.
