Space flight, simulators, astronomy, books, flying, music, science, education: whatever the obsession of the moment might happen to be.

Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.
-Margaret Mead
The methods and values of scientific thinking have expanded our knowledge about life and our place in the universe. This modern knowledge—based on experience and evidence—has brought enormous benefit to humanity, yet many people still choose to rely on ancient texts and beliefs to guide their lives and their nations.
The Center for Inquiry exists to change this situation. We are here to promote the scientific outlook, to expand the methods and values of science into all areas of human endeavor.
The Carnival of Space has a slightly unusual but timely host this week - the web site of the .astronomy conference that will be held in Cardiff, Wales next week (September 22-24).
No, it's not Obama! Well, not in the same way. I'm actually in love with my new 16 GB Apple iPod Touch. I came very close to buying one of the first generation models when they came out (a year ago?). But I decided the lack of a hardware volume control was a deal breaker for using it in the car (turns out it probably would have been OK). I also thought the price vs. memory value wasn't that good with the first models. This one was $299 for 16 GB which seems like a good balance.
Whatever Apple's and Steve Jobs' faults, they create products that truly are a pleasure to use. I owned and enjoyed a Mac from 1984 to 1994 when practical considerations pushed me to PC's and Windows, and with rare exceptions, computers have just been tools for me since then. The iPod Touch reminds me of what it's like to experience geek love for a really well designed product, a pocket computer orders of magnitude more powerful than my original 1984 Mac.
I just learned about this from a member of my astronomy club. Michigan Tech University is offering an introductory astronomy class this semester (PH1600), taught by Professor Robert-J.-Nemiroff. The lecture videos are available through iTunes U and as direct downloads from Learnoutloud.com.
Although it's very narrow indeed, Obama has opened up a slight lead over McCain in the latest CBS/NY Times and Reuters/Zogby polls. This suggests that the GOP convention/Palin "bounce" has been damped out, and that the disasters on Wall Street are reminding voters that the economy matters more to them than lipstick and moose (mousse?). McCain is trying to distance himself from the Bush administration on the economy, but it doesn't seem to be working very well. I'm sure they're cooking up some fresh lies and dramas for the coming weeks to try to distract voters from the issues as Palin has done for a couple of weeks now.
In my last post, I referenced the NSS space settlement art contest and calendar, and this reminded me of something I've been meaning to write about for some time - the Lifeboat Foundation "Ark I" space settlement concept. The Lifeboat Foundation is a private foundation that is studying ways to protect humanity from various "existential risks" - things that might wipe us out, ranging from runaway biotechnology or nanotechnology to various terrorist actions (biological, nuclear, etc.) to asteroid strikes and more. They have many interesting people studying a lot of cool defensive ideas, but if the worst happens, they are also looking into space settlements, self-sustaining space colonies that could allow at least some human beings to survive to preserve our legacy and perhaps rebuild our civilization.
The picture above is an artist's impression from the Lifeboat site, not an Orbiter shot. It would be cool to have Ark I and the waverider space planes in Orbiter - I'll ask around and see if any add-on developers are interested in modeling these for Orbiter. There is one historic space settlement concept that was developed as a nice add-on for Orbiter, the Stanford Torus, shown at left. This design was the result of a 1975 space habitat workshop that was inspired by the early space colony ideas of the late Gerard K. O'Neill. The white disk is a reflector used to direct and control sunlight for the living areas on the inside surface of the toroid. More Stanford Torus pix from Orbiter here.
From recent posts, you might think the theme of this blog has morphed from space/education/science/astronomy/etc. into politics, but that is definitely not my long term plan. I normally maintain a Newsweek-level interest in politics, keeping up with important developments, but not getting too distracted by them. This fall's presidential election is a major exception, and I have gotten more involved with it than I expected, with fund raising and even canvassing and making phone calls for the Obama campaign, in addition to writing about it. I believe it's really important, and I can't help it - I want my country back. But I haven't given up on the "space stuff" by any means.
I had a great day in New Hampshire yesterday. First I joined a large and enthusiastic crowd in Manchester to hear Barack Obama speak. While he covered most of the same points made in his acceptance speech in Denver, he updated many of the comparisons between his plans and those of John McCain, with a lot of emphasis on how the economy is impacting so many Americans, and how McCain doesn’t seem to really understand this or have any plans that will help.
The “personal” part took place in the afternoon, which I spent canvassing for the Obama campaign in a small town near Keene, NH. Accompanied by an experienced local volunteer and with a big assist from my GPS, I visited around 25 homes in this rural area and spoke to a number of voters, including a good number of Obama supporters and a few undecided voters. Naturally some people were not interested in any political callers, and a few others were solidly for McCain. Usually we just thanked them for their time and moved on, but in a few homes where the person seemed open to discussion, I asked why they liked McCain over Obama. In a couple of cases, their response was clearly based on misconceptions (e.g., Obama will raise my taxes), and I was able to plant some seeds of doubt. Maybe some will change their minds, or at least dig a little bit for the facts. You never know.
Tomorrow I will take another leap from my personal comfort zone and drive up to New Hampshire to canvass for Barack Obama. While Massachusetts should be pretty "safe" for Obama, New Hampshire is a battleground state that has been decided by fewer than 10,000 votes in the last two presidential elections (went for Bush in 2000, Kerry in 2004). So I will join a lot of other Obama supporters in trying to convince undecided New Hampshire voters to vote for Obama-Biden. I've also signed up to do this on a few more weekends this fall. I don't have any idea how it will go (I haven't done this since 1972 when I campaigned in college for George McGovern!), but I can talk with people about the issues, and I won't take it personally if a few of them slam the door in my face.
The Carnival of Space is back with a lot of cool posts to explore, hosted this week by Orbital Hub. Check it out.
Now this is some cool solar technology. How do you make concentrating solar collectors cheap? Make them out of plastic sheeting and blow them up to the right shape like balloons! That's the basic idea from CoolEarth Solar. The inflatable collectors can be cheap enough to replace every two years, and they are so light, that the structure for mounting them and tracking the sun can also be light and fairly simple. As they say in this PDF presentation, "solar farming" should be taken more literally - make the individual parts cheap and scalable, like growing wheat in a big field, as opposed to growing it in a greenhouse.Our approach is to suspend concentrators on support and control cables stretched between poles. The ground under the concentrators is shaded only by about 10% and remains free for other uses like farming or ranching. Suspending the concentrators also preserves habitat. It is also inexpensive: telephone companies, ranchers, and farmers have already figured out how to set posts cheaply across vast spaces.Cool indeed.
Thanks to a post on Orbiter-Forum.com, I just discovered a really cool web site on all things related to the Russian manned space program. Космонавтка (Kosmonavtka, "female cosmonaut") is the work of Suzy McHale, who hails from Melbourne, Australia (a lovely city I got a chance to visit two summers ago). It covers everything from the cosmonaut roster to the Soyuz spacecraft to personal hygiene kits (and much more).I went to the Great New England Air Show at Westover ARB in Chicopee, Massachusetts today. It was cool. The weather was terrible yesterday, so I and basically everyone in New England went today, leading to enormous traffic delays getting in and out. But it had been about three years since my last air show, and it was worth a little traffic frustration.
Eating junky air show food on the sunny tarmac, inspecting and photographing planes I've seen dozens of times, watching amazing aerobatic and parachuting performers - I've been doing this since I was ten years old, and it's still fun. I just love stuff that flies!
The USAF Thunderbirds were the featured act and I was happy to find that Thunderbird #5 (lead solo) was flown by a woman, Major Samantha Weeks. Major Weeks is not the first woman to fly the F-16 with the Thunderbirds (that was Major Nicole Malachowski in 2006), but she was the first I had seen perform. Of course she was amazing, as you would expect from a member of this elite precision flying team.
I saw some other interesting airplanes, including a ski-equipped LC-130, and I talked with the weapons officer of a B-52. I was sitting in traffic when the USMC AV-8 Harriers flew, which was a disappointment. I've seen Harriers in static displays at several shows but never saw a flight performance by this V/STOL aircraft (the one flown by Arnold Schwarzenegger in the movie "True Lies" - a very cool albeit highly implausible scene). I have a few more pictures on Flickr.
Science and technology are vitally important to the future of this country and indeed the world. Voters should know the positions of the candidates on these vital issues. Science Debate 2008 is a grassroots initiative to encourage the presidential candidates to debate the most important questions in science. This initiative is supported by leading scientific and engineering organizations, universities, and many individuals including Nobel Prize winners. They have received over 3,400 questions from 38,000 individual signers, and they have distilled these down to the 14 most important questions, stated to encourage discussion and embellishment in a debate setting.
Free Space gives us an alphabetical tour of twenty-six space and astronomy blog posts at this week's Carnival of Space. Check it out.
I’m heading home Friday after a busy week in Glasgow, and with this very flaky hotel internet connection, I haven’t had much of a chance for blog reading or writing. But I did manage to read a great post on solar sails tonight at Centauri Dreams. Paul Gilster reviews an interesting new book, Solar Sails: A Novel Approach to Interplanetary Travel.
The solar sail configuration file says its area is 2800 (presumably square meters, about 53 meters square). This looks about right compared to the shuttle I inserted in the second picture for scale (shuttle length is about 37 meters). So this is not an interstellar sail, but it lets you play around to see how these things work. The included scenario starts you in a near-circular Earth orbit at about 1220 km altitude where you can separate from an upper stage (J), wait a few minutes for clearance, and deploy the sail (D). The animation is pretty cool.
So far Glasgow seems like a pretty nice city. I’ve only explored the area around Glasgow Caledonian University which is hosting the conference I’m attending this week. I arrived this morning in heavy rain, but by early afternoon it had gotten sunny and I spent some time walking around after lunch. I wish I had some pictures of my own to show, but the digital camera I bought at the last minute (long story) doesn’t work. I bought a couple of cheapo disposable film cameras and but I won’t know the results for a while, a rather retro experience in the digital gratification era.
I always explore bookstores, even in Germany, Taiwan, and Japan, but the nice thing about UK bookshops is I can actually read the books and magazines. I spent some time in Borders (I know, that’s American, but the books are different) and in Waterstones, a UK stalwart. I like the fact that there’s a magazine here called Spaceflight, and I bought the September issue. Serendipity struck in the science section with the late Ernst Mayr’s 2001 book What Evolution Is. This has put Tom Kelly’s LM book on temporary hold, and three chapters in, I really like it. More later, probably. Most of those three chapters were read this evening over a couple of pints of Guinness in a nearby Irish pub, so I’m ready to call it a long jet-lagged day.
