In 1973, the USSR launched Mars 5, on a Proton SL-12/D-1-e booster. It was one of several Soviet Mars probes - Mars 4, 5, 6, and 7 - launched in Jul-Aug 1973.

However, after only 22 orbits, the mission ended prematurely due to loss of pressurization in the transmitter housing.

The probe also sent more measurements made by other instruments.«
