RE Arecibo funding. They want to cut the funding.. hey guys it's a an opportunity like no other for the next ten years minimum. Sole source of how many kinds of data. And it looks like the price is operational cost and upkeep only.... Why don't we just fund it ourselves? I'm nuts and it runs in the family OK.... My father was one of the guys that kicked in the bucks to fund the first OSCAR.. amateur radio satellite. Oh my...was that 40 years ago... So figure we'd have to carry the Big Baby 15 years before the next big array really would be fully on line.. with how many members and a general inflation rate of... This may be the investment opportunity of a life time. Ok Ill crawl back under my rock. best weird george |

Just was reading last night. The SETI Institute has searched over 1000 stars since 1995. They now have the Allen Array coming on-line. Claims are it's possible to hear airport radar out to 200 light years. New probes in space with a larger than Hubble telescope are expected to find many more Earth sized planets so SETI search can be concentrated looking for Narrow band signals. New enlightenment on probabilities in the Drake equation put the closest ET estimate at 45 light years and also maybe we are the only ones in the Galaxy-ET would need : A moon to tidally lock the Planet to stabilize the spin. Large gas planets in outer orbits to shield the planet from comets Nearly circular orbits for all planets for climate stability and to keep Jupiter-sized plants from crossing planets orbits and flinging it out into space. Spread spectrum communications are more likely to be heard say when compared to single (narrow band) communications in the sense that the signal would be easier to detect for a given amount of power The Allen array will produce many more "looks " than the Arecibo Dish. We beamed our only Hello message out to a Distant Galaxy 30,000 + light years away (?) With new stuff coming on line maybe we need to pool resources and concentrate on the most likely avenue of success. Perhaps Arecibo should become our narrow band beacon. What's the cost to kep it going? |
