The landers were identical to that of the previous five ''[[Venera]]'' missions and were to study the atmosphere and surface. Each had instruments to study temperature and pressure, a [[UV]] spectrometer, a water concentration meter, a [[Gas-liquid chromatography|gas-phase chromatograph]], an [[X-ray]] [[spectrometer]], a [[mass spectrometer]], and a surface sampling device.

The ''Vega 1'' lander's surface experiments were inadvertently activated at {{cvt|20|km}} from the surface by an especially hard wind jolt, and so failed to provide results. It landed at 7.5°N, 177.7°E.

The ''Vega 2'' lander touched down at 03:00:50 UT on 15 June 1985 at 8.5° S, 164.5° E, in eastern [[Aphrodite Terra]]. The altitude of the touchdown site was {{cvt|0.1|km}} above the planetary mean radius. The measured pressure at the landing site was 91 atm and the temperature was {{convert|736|K}}. The surface sample was found to be an [[anorthosite]]-[[troctolite]]. The lander transmitted data from the surface for 56 minutes.{{Citation needed|date=November 2023}}
