NASA posted this update on its website today. No nuclear power for the next mission and list of acceptable candidate missions likely to come this spring:

"The National Aeronautics and Space Administration (NASA) Science Mission Directorate (SMD) plans to release an Announcement of Opportunity (AO) for the third New Frontiers (NF-3) mission no earlier than June 2008. Downselection would occur in 2009. This NF-3 AO will solicit only missions that do not require nuclear sources for power generation or propulsion.

Once the National Research Council's (NRC's) New Opportunities for Solar System Exploration (NOSSE) committee reports to NASA on mid decade NF science mission priorities in March 2008, NASA plans to release more details about allowed targets for the upcoming NF-3 AO."

Thanks, VJ; makes sense. They might also be trying to drive innovation by imposing such a fundamental constraint, but I'm still not wild about it.

Increasingly, the outer Solar System is where most of the really intriguing things in planetary exploration seem to be, and it would be nice to see a process/administrative framework dedicated to encouraging its exploration. Solar-powered Saturn probes are just barely within the realm of the possible, but for Uranus & beyond...fuggetaboutit.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
