The mean stable height was 53.6 kilometres (33.3 mi), with a pressure of 535 millibars (535 hPa) and a temperature of 308–316 K (35–43 °C; 95–109 °F) in the middle, most active layer of the Venus three-tiered cloud system. The balloon drifted westward in the zonal wind flow with an average speed of about 66 metres per second (220 ft/s) at nearly constant latitude. The probe crossed the terminator from night to day at 9:10 UT on 16 June after traversing 7,400 kilometres (4,600 mi). The probe continued to operate in the daytime until the final transmission was received at 00:38 UT on 17 June from 7.5 S, 76.3 E after a total traverse distance of 11,100 kilometres (6,900 mi). It is not known how much further the balloon traveled after the final communication.

The balloon package was pulled out of its compartment by parachute 40 seconds later at 61 kilometres (38 mi) altitude, at 7.45 degrees S, 179.8 degrees east. A second parachute opened at an altitude of 55 kilometres (34 mi), 200 seconds after entry, extracting the furled balloon.

The balloon was inflated 100 seconds later at 54 kilometres (34 mi) and the parachute and inflation system were jettisoned. The ballast was jettisoned when the balloon reached roughly 50 kilometres (31 mi) and the balloon floated back to a stable height between 53 and 54 kilometres (33 and

The Vega 2 Lander/Balloon capsule entered the Venusian atmosphere (125 kilometres altitude) at 02:06:04 UT (Earth received time; Moscow time 05:06:04) on 15 June 1985 at roughly 11 kilometres per second (6.8 mi/s). At approximately 2:06:19 UT the parachute attached to the landing craft cap

Vega 2 made its closest approach at 07:20 UT on March 9, 1986, at 8,030 kilometres (4,990 mi). The data intensive examination of the comet covered only the three hours around closest approach. They were intended to measure the physical parameters of the nucleus, such as dimensions, shape,

The descent module arrived at Venus on 15 June 1985, two days after being released from the Vega 2 flyby probe. The module, a 1,500 kilograms (3,300 lb), 240 centimetres (7.9 ft) diameter sphere, contained a surface lander and a
