1 Venus: NASA HQ Perspectives National Aeronautics and Space Administration Andrew Danztler Planetary Division Director Adriana Ocampo Venus Discipline Scientist Pasadena, USA 1-2 May

2 Venus Express (ESA) CONGRATULATIONS to VeX Team for a successful VOI!!!!!!! Looking forward to great science results NASA is happy to be part of Vex via: Participating Scientist (10) And Interdisciplinary Scientist and Support Investigators (soon to be announced) Timely results from VeX will help define the next steps for Venus exploration Ref: ESA 2

3 Venus Exploration Analysis Group (VEXAG) VEXAG plays a key role to identify scientific priorities and strategy for exploration of Venus. Voice for the scientific community. Forum for coordination VEXAG working together with Venus Express needs to include the latest findings and fold them into Venus scientific priorities. VEXAG will report on the community assessment and provide input to NASA, but will not make recommendations. Key to work together with other assessment groups (OPAG, MEPAG, etc) to have an integrated program 3

4 Potential Future Missions: Discovery / New Frontiers Classes Next Step: NASA s s Options for Venus Exploration in the near term Discovery Program (<$350M) PI-led and competitively selected (6 to 7 per decade) Venus concepts have been proposed at each opportunity; Include orbiter, probe, lander and balloon concepts; Discovery 12 Announcement of Opportunity has close and the proposal are under review New Frontiers Program (<$650M) PI-led and competitively selected, but to a specified set of targets (4 per decade) Announcement of Opportunity expected in late 2008 or 2009 Two mission selected, New Horizons (Pluto) and Juno (Jupiter) International collaboration and coordination - Mission of Opportunity via Discovery and New Frontiers 4

5 Summary VeX results are important for future exploration of Venus, off to a a great start VEXAG play a key role to coordinate the scientific community and prioritized objectives NASA near term path for Venus exploration are the: - Discovery Program - New Frontiers 5
