The Mars 2 through Mars 7 spacecraft were of a new, heavy design, weighing approximately 5 metric tons and requiring the Proton booster for launch.
It was announced that Mars 2 and 3 had completed their missions by 22 August 1972, after 362 orbits completed by Mars 2 and 20 orbits by Mars 3.
Mars 96 was an orbiter launched in 1996 by Russia and not directly related to the Soviet series of probes.

 Mars - Wikipedia, the free encyclopedia
Mars has only a quarter the surface area of the Earth and only one-tenth the mass (though its surface area is approximately equal to that of the Earth's dry land because Mars lacks oceans).
The atmosphere on Mars is 95 percent carbon dioxide, 3 percent nitrogen, 1.6 percent argon, and traces of oxygen and water.
The datum for Mars is defined by the fourth-degree and fourth-order spherical harmonic gravity field, with the zero altitude defined by the 610.5 Pa (6.105 mbar) atmospheric pressure surface (approximately 0.6% of Earth's) at a temperature of 273.16 K. This pressure and temperature correspond to the triple point of water.

The Mars 96 spacecraft was launched into Earth orbit, but failed to achieve insertion into Mars cruise trajectory and re-entered the Earth's atmosphere at about 00:45 to 01:30 UT on November 17 1996 and crashed within a presumed 320 km by 80 km area which includes parts of the Pacific Ocean, Chile, and Bolivia.
The Russian Mars 96 mission was designed to send an orbiter, two small autonomous stations, and two surface penetrators to Mars to investigate the evolution and contemporary physics of the planet by studying the physical and chemical processes which took place in the past and which currently take place.
Mars 96 was scheduled to arrive at Mars on September 12 1997, about 10 months after launch, on a direct trajectory.

 USGS Astrogeology: Mars MDIM Digital Image Mosaic
This mosaic, known as Mars Digital Image Model (MDIM) 2.1, replaces two earlier mosaics produced by the USGS from the same set of approximately 4600 Viking Orbiter images.
The positional accuracy of features in MDIM 2.1 is estimated to be roughly one pixel (200 m), compared to 3 km for MDIM 2.0 released in 2001 and >6 km for MDIM 1.0 released in 1991.
In addition to relatively imprecise geodetic control, the previous mosaics were affected by changing definitions of cartographic parameters (such as the definition of zero longitude), resulting in an overall longitude shift of as much as 0.2° between the early MDIMs and other datasets.
