Terrestrial Planet Finder (TPF) - Building on the technology tested by SIM (above) NASA's proposed TPF is an even more ambitious mission to launch five spacecraft to fly in formation, with four of them carrying telescopes to combine the light of a star system into one image, while simultaneously nulling out the bright parent star to detect Earth-like planets and determine what their atmosphere is composed of (which may betray the presence of life).

I have just become a presenter for the NASA Night Sky Network where members of numerous astronomy clubs get materials to present to the public. One of the fantastic items that they had is 12 monthly all-sky star maps (as seen from 35 deg. North latitude) which show the positions of easily found extra-solar planet parent stars which are titled Where are the Distant Worlds?

Jason's SETI To-do List:

Bug-Eye 12 gigahertz multi-dish wide-angle radio sky viewer feasibility study - to see if using multiple 2-3 degree wide 12 gigahertz satellite dishes would be useful.

Central SETI Target Master Catalog - identify known studied SETI candidates by different researchers into a central archive.

Optical Satellite Identification/matching - I've seen a satellite suddenly slow down, reverse direction, and then stop. I heard another person report the same thing for a different location at a different time on a radio talk show. Is this possible for a satellite with known technology without burning all its reaction thruster fuel? I have found a similar account online. I must set aside observing time t next astronomy club dark sky outing

Earth Shadow Optical Telescope Experiment - Look in Earth's shadow for optical flashes from ET civilizations.
