Neil deGrasse Tyson (stage left) is an American astrophysicist, science communicator, the Frederick P. Rose Director of the Hayden Planetarium at the Rose Center for Earth and Space, and a Research Associate in the Department of Astrophysics at the American Museum of Natural History. Since 2006 he has hosted the educational science television show NOVA scienceNOW on PBS, and has been a frequent guest on The Daily Show, The Colbert Report, and Jeopardy!.

He let loose a with a series of tweets today (@neiltyson) before the launch of STS 135, Atlantis. I'm going to quote a few of his tweets, and offer my own piquant observations.
@neiltyson Many lament the shuttle era's end. But that's misplaced sentiment. Lament instead the absence of an era to replace it.
He's absolutely right. As he would go on to tweet, we had Mercury leading directly into Gemini, which then led directly into Apollo and the moon landings. Unfortunately when they stopped Apollo at 17, launched in December 1972, there wasn't another manned program ready to launch like there'd been for Apollo. There was a confused pause on the part of Nasa, a troubling precident.

Nasa filled the gap, as it were, with Skylab. Skylab was launched 14 May 1973 (chronologically not long after Apollo 17) and stayed in orbit until it re-entered the Earth's atmosphere on 11 July 1979. A product of the Apollo Applications Program, it was one of two space stations that were meant to be orbited.

Unfortunately, due to budget constraints the second Skylab was never launched, and now sits as an exhibit in the at the National Air and Space Museum in Washington D.C. It never launched because Nasa's nascent Shuttle program was pulling in Nasa funding the way a black hole sucks in matter, leaving no funding to prep Skylab B and the Saturn V needed to place it in orbit.
@neiltyson No. I'm not in Florida for the launch today. I'm a much bigger fan of when things begin than of when they end.
Yeah, I kinda sorta know how he felt. I tried twice to win a slot on Nasa's Tweetup, but I lost out both times. I guess I wasn't important enough to rate.
@neiltyson The US military spends as much in 23 days as NASA spends in a year - and that's when we're not fighting a war.
@neiltyson The entire half-century budget of NASA equals the current two year budget of the US military.
When you consider the trillions spent everywhere else in the federal budget, it's amazingly hypocritical of Nasa's many critics to claim that Nasa's budget is a waste. Yes, there are overruns and schedule slips to the right for Nasa programs. But how many hundreds of billions, nay trillions, have been wasted on innumerable DoD contracts?
@neiltyson Apollo in 1969. Shuttle in 1981. Nothing in 2011. Our space program would look awesome to anyone living backwards thru time.
Or to look at it in a different way: Nasa's budget since 1975 has been 1% of the federal budget or less, too many times far less. The only time it exceeded 1% was from 1962 to 1974, with the development of Mercury, Gemini, Apollo, and the launch of Skylab. A tremendous amount of science and engineering was accomplished in those days. Throttling Nasa's budget's to %1 or less of the federal budget since 1975 brought us the long-strung-out Shuttle program and the ISS over the next 30 years. And with the end of Shuttle, all we have left is the ISS.

Neil doesn't seem to have much use for commercial space (SpaceX, for example). The problem with that attitude is with a tacit approval of Big Space. Big Space is the same guilty group that have given us the Military Industrial Complex and the trillions spent and wasted on defense. Big Space turned the Shuttle program into their own personal jobs program. We got a very expensive spacecraft and a very expensive LEO space station that pretty much sucked precious funding into it, leaving little left for pure planetary science.

We need commercial space to actually give us what Shuttle promised and never delivered; low-cost access to space. Yes, commercial space will take us to where we've been before. But that's not the point. By way of analogy, the early microprocessors were giving us what we already had in minis and main frames. Except it made computing dirt cheap and extremely accessible. The explosion of creative that resulted helped shape the world we live in today.

It would be great if we could reproduce that same kind of explosive creativity for space travel. We won't have dirt cheap personal rockets, but we will have access to space orders of magnitude cheaper than what the old guard in Big Space have given us. And we need that. I don't ever want to see anything like the Shuttle program created again for the U.S.

A Decade Long Religious Con Job

I rarely write inflammatory (what some might call trolling) titles to a post, but this building you see before you deserves it. I've been seeing this building next to I-4 just east of Altamonte/436 and Crane's Roost for nearly 12 years, and never knew who owned it. Today on a trip up to Lake Mary with my wife I saw it yet again. That's when I told her I wanted to stop by on the way back and poke around the property, and photograph any parts of it if I could.

What I discovered was this still unfinished eighteen story (I counted) white elephant, overgrown with weeds and yet still under slow-motion construction. It looks impressive with its exterior glass curtain walls, but that impression is quickly lost when you see the unfinished lower stories and look inside to the unfinished interior spaces.

A quick check via Google leads to an article written in 2010 by the Orlando Sentinel about the Majesty Tower. Based on what I read in the article it's owned by SuperChannel 55 WA…

Be Careful of Capital One Mailings

Capitol One ("What's in your wallet?") sent me a bit of deceptive snail mail today. I felt sure it was a credit card offer, and sure enough, it was. I open all credit card offers and shred them before putting them in the trash. Normally I just scan the front to make sure I don't miss anything; the Capital One offer made me stop for a moment and strike a bit of fear into my heart.

The letter's opening sentence read:
Our records as of December 30, 2009 indicate your Capital One Platinum MasterCard offer is currently valid and active.Not paying close attention during the first reading, I quickly developed this irrational worry that I was actually on the hook for something important, but I wasn't quite sure what. The letter listed "three ways to reply" at the bottom; via phone, the internet, and regular snail mail. I elected to call.

Once I reached the automated phone response system, the first entry offered was '1', to "activate my Capital …

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…
