Mel's Arecibo Adventure
Let me introduce you to Mel. He's a little stuffed koala that my wife and I take on our travels, and as it turns out we much prefer to take pictures of where Mel has been been than where we've been.
Last week Mel found himself in Puerto Rico, where I was covering the 41st annual meeting of the American Astronomical Society's Division for Planetary Sciences. After the meeting concluded, we headed west from San Juan to visit Arecibo Observatory.
I'd been to Arecibo before, but on this particular visit I was keen to see the big dish in action. Luckily, that evening astronomer Marina Brozović (Jet Propulsion Laboratory) planned to "ping" a small near-Earth asteroid designated 1999 AP10 to try to determine its shape and surface characteristics.
These are challenging times for the observatory. In 2006, a top-level review for the National Science Foundation concluded that the facility should either find funding from non-NSF sources or be closed. Even though an National Research Council report released last month affirms that the observatory provides "unmatched precision and accuracy" in detecting asteroids or comets that could hit the Earth, as things stand now there'll be no more money to fund Arecibo's unique radar capability after fiscal year 2010. You can get more background via the Arecibo Science Advocacy Partnership (ASAP).
I'll have more to say about Arecibo's precarious future at a later date, but for now let's get back to Mel's excellent adventure. As the photos below attest, the observatory is an amazing place. In a few years it may no longer be the world's largest radio dish, but for now there's no place like it on Earth.
Mel thanks staffers Mike Nolan and Ellen Howell, who paved the way for his visit and also served as gracious hosts.

Thanks for the tour!

So great to see the people and the environment of such an iconic piece of wonder in astronomical science. I am a huge fan of "Contact" and really enjoyed seeing inside what we only get a glimpse of in the movie. Looks like there are still a few Ellen Arroways left working there, but are any of them listening for an intelligent message from beyond? Perhaps we are beyond listening, as they may already be here making contact in person.
Arecibo Telescope Closed?

I grew up in Puerto Rico. I saw the amazing sight of a structure apparently brought here from the 24th century when it was brand new. Thomas Gold. Cornell University. This was big, impressive news.
Now I hear it may be closed in a few months. How sad! This magnificent window into the universe that we're just beginning to understand will be closed before we even get to the 24th century.
Is there anything a fan out here on the west coast of the US can do to help avert the closing? Before it gets converted to a skateboard park?

Awesome!

Thought I recognized this dish (not Ms. Brozovic, although she's a dish also). Just finished watching "Contact" the other night. Never realized how truly awesome this massive dish is. And like in the movie, money is always the bottom line, sadly. "No bucks, not Buck Rogers", as the saying went in the movie "The Right Stuff". But this dish has all the right stuff, just needs a better selling job to the public, I guess.
Closeing of Arecibo bad idea

It wpuld be a bad idea to close the telescope. But if the money runs out, they will have no choose but to close it. I hope the obsevitory can get the funds.

Let's not dwell on the closing......let's figure out how to save this treasure, starting NOW. My observtions conclude, as others have, that Ms Brozovic is indeed a considerable dish, but on a different "curve" plane.

As of this moment, 2 of 7 comments are about the appearance of one of the female researchers. No wonder women are put off getting into science.

Interesting photos -- "alien spaceship" & aerial shots are very cool.
Maybe Mel's adventures in astronomy should be a regular feature? :)
Arecibo Radio Telescope

My first engineering job after graduating from Bucknell U. (1963) was for Praeger-Kavanagh (the consultant for the telescope's design & construction) in Arecibo. A wonderful experience! Using precision instruments, we meticulously established exacting locations for dish tiedowns & the superstructure. The construction tolerances were miniscule vis-a-vis conventional engineering projects. The work was fun, the experiences unique. Thanks for reviving this long-ago adventure, my first outside the contiguous 48. Arecibo & friends will always be fondly remembered.
