1985年6月，作为织女星（VEGA）任务的一部分，两个装有仪器的气球被放置在金星的大气层中。每个气球在约54公里的漂浮高度绕行星飞行了大约30%的路程。原位传感器测量了气压、温度、垂直风速、云粒子后向散射、环境光照水平和闪电频率。一个由20个无线电天线组成的地面网络通过甚长基线干涉测量（VLBI）技术跟踪气球，以监测金星的风。本文描述了这个国际气球实验的历史、组织和主要特点。
In June 1985, two instrumented balloons were placed in the atmosphere of Venus as part of the VEGA mission. Each balloon traveled about 30 percent of the way around the planet at a float altitude near 54 kilometers. In situ sensors measured pressure, temperature, vertical wind velocity, cloud particle backscatter, ambient light level, and frequency of lightning. A ground-based network of 20 radio antennas tracked the balloons by very long baseline interferometry (VLBI) techniques to monitor the Venus winds. The history, organization, and principal characteristics of this international balloon experiment are described.
