2007 TU24 to be Radar Imaged in Great Detail.
http://www.spaceflightnow.com/news/n...id/index2.html
We were all waiting for this announcement. Arecibo is a science jewel. |

Arecibo is going to be closed down, the univesity can't find anybody
with the money to keep it open. A shame too since they just finished an upgrade and repainting not too long ago. |

..
If they get some really good shots of TU24, maybe they will reconsider. Asteroids are a major threat. Not bloody likely, until AFTER a BIG ONE hits and causes major panic. Only THEN will there be a political scramble for more and better sapceguard funding and deployment. Absent that major knock onthe head, don't count on politicians to do anything about it. They can't think ahead any further than their next election. "If they get some really good shots of TU24, maybe they will reconsider." Not unless they charge 2 million per picture. I think that's the bare minimum the University spends on annual operations for "El Radar". Could be more. Federal funding was cut with NASA's official blessing, of course they just do what the President tells them. No bucks, no Buck Rogers. There are none so blind as those who will not pay to let the telescope continue to see. When they shut down Aricebo, the Goldstone dish will be the largest remaining operational radio telescope I know of that's at all steerable. Goldstone, last I read, is usually tied up most of the time for DSTN and planetary probe communications work. There may be a powerful radar/radio telescope in Russia somewhere that's bigger, but their programs are even more destitute than ours, it's probably been turned into condos for nuveau-rich oil oligarcs and Russian mafiosi. Things look bleak and the best "hope" is to pray for a disaster, not good. |

Back to the topic at hand, there are preliminary images : http://www.centauri-dreams.org/?p=1692 Hopefully Arecibo will do better. |

When they shut down
Aricebo, the Goldstone dish will be the largest remaining operational radio telescope I know of that's at all steerable. Effelsberg in Germany is larger (100 m vs 70 m dish diameter) and is used for research exclusively. But loosing Arecibo will really be a shame. Jan |

Don't forget the dish array at Westerbork, see
http://www.astron.nl/p/WSRT2.htm Also http://en.wikipedia.org/wiki/Green_Bank_Telescope (about 100m, steerable). But Arecibo, at 305 m, is much larger than any of these (although it is only slightly steerable, so you have to wait for your target to pass over the dish). |
