VEXAG Goals and Exploration Sites Focus Groups

The Venus Exploration Analysis Group is NASA's community-based forum designed to provide scientific input and technology development plans for planning and prioritizing the exploration of Venus over the next several decades, including a Venus surface sample return. VEXAG is chartered by NASA's Solar System Exploration Division and reports its findings to NASA. Open to all interested scientists, VEXAG regularly evaluates Venus exploration goals, scientific objectives, investigations and critical measurement requirements, including especially recommendations in the NRC Decadal Survey and the Solar System Exploration Strategic Roadmap.

In addition to interested members of the scientific community, each focus group will include technology experts, NASA representatives, international partner representatives, EPO experts, and the chair. The current focus groups are listed below. Other focus groups may be added, as needed.
