The Venus Exploration Analysis Group

Unveil Venus:  Why is Earth's sister planet so different?

VEXAG was established by NASA in 2005 to identify scientific priorities and opportunities for the exploration of Venus, Earth’s sister planet. The group has an open membership and an 7-person Executive Committee, 3 Focus Groups, and 2 Topical Analysis Groups. Input from the scientific community is actively sought. The VEXAG provides findings to NASA Headquarters, but does not make recommendations. Stay in touch by visiting our Twitter and Facebook pages!

VEXAG Charter

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. 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.
