The lander and its [[aeroshell]] separated from the orbiter on 3 September 19:39:59 UT. At the time of separation, the lander was orbiting at about 4 km/s. After separation, rockets fired to begin lander [[deorbit]]. After a few hours, at about 300 km attitude, the lander was reoriented for entry. The aeroshell with its ablative [[heat shield]] slowed the craft as it plunged through the atmosphere.

The Viking 2 Lander touched down about 200 km west of the crater Mie in [[Utopia Planitia]] at {{Coord|48.269|N|225.990|W|globe:mars_type:landmark_dim:100|display=inline,title}} at an altitude of -4.23 km relative to a reference ellipsoid with an equatorial radius of 3397.2 km and a [[flattening]] of 0.0105 ({{Coord|47.967|N|225.737|W|globe:mars|name=Viking 2 landing site planetographic}} [[Longitude#Longitude on bodies other than Earth|planetographic]]) at 22:58:20 UT (9:49:05 a.m. local Mars time).

Approximately {{convert|22|kg|abbr=on}} of propellants were left at landing. Due to radar misidentification of a rock or highly reflective surface, the thrusters fired an extra time 0.4 second before landing, cracking the surface and raising dust. The lander settled down with one leg on a rock, tilted at 8.2 degrees. The cameras began taking images immediately after landing.
