Even as the National Science Foundation (NSF) proceeds with the disassembly of the destroyed Arecibo radio telescope in Puerto Rico, some astronomers are proposing that a new radio telescope be built in its place, with a new design that will not require the instrument platform floating above a single dish.
Here’s the idea as outlined in a white paper circulated by Roshi and his colleagues: The Next Generation Arecibo Telescope would pack hundreds, maybe even more than 1,000 smaller radio dishes into the same space now occupied by the single 305-meter dish. Those smaller antennas would combine forces to act like a single larger telescope (no suspended instrument platform required).
Ideally, those dishes would be on a single, tiltable platform to access more of the sky from the Arecibo site; it’s possible multiple platforms could do the same.
The revamped telescope would have twice the sky coverage of the legacy dish, 500 times the field of view in individual images, at least double the sensitivity, and five times the radar power.
The cost for this new radio telescope is presently estimated to be about half a billion. Considering that the NSF didn’t have the money to operate the old Arecibo telescope, which was why it wasn’t properly maintained and collapsed, I doubt it has the cash to build this replacement. Congress, which likes printing money it doesn’t have, might step in and fund it, but if so that will only add to the national debt that is certainly going to cause the bankruptcy of the nation at some point in the future, a point that is getting closer and closer with each new trillion that Congress nonchalantly spends, on almost a monthly schedule.
From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.
Unfortunately, that is exactly where that journey takes him.
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.
He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.
