    The 2006 York Maize Maze pays tribute to characters from the "Star Trek" saga.


    If you build it, will they beam down? "Star Trek" fan Tom Pearcy cut this maze in a cornfield on his farm near York in northern England, to celebrate the 40th anniversary of the science-fiction classic's first TV show. Pearcy claims it's the largest such labyrinth in the world. In its report, the Reuters news service says Pearcy used satellite imagery as a guide for the maze, which takes in 1.5 million corn plants. Fascinating.

  • Bigelow's orbital 'baby'

    Real-estate billionaire Robert Bigelow, the head of the world's newest orbital space program, says he thinks of his Genesis 1 inflatable module as "our baby" - and lies awake at night wondering how "she" is doing. On the day after the big launch, Bigelow chatted with me about the regulatory hoops he and his team had to jump through, the bugs and jumping beans that are aboard Genesis, and the road ahead to human orbital flight.

    fully inflated, with solar panels deployed.


    Just to refresh your memory, Genesis 1 is a one-third-scale prototype for what Bigelow Aerospace hopes eventually will be the building blocks for private-sector space stations: prefab modules that can be compressed down for launch, then inflated in orbit like balloons with bulletproof skins. The 14-foot-long, 4-foot-diameter spacecraft was launched Wednesday from a Russian military base atop a converted Soviet-era ICBM - and all indications so far are that the craft performed precisely as planned. (Today's mission update says the first images have been sent down from the onboard cameras.)

    "This is like the day after a war," Bigelow told me over the phone today from his Las Vegas headquarters. "We have a lot of walking wounded around here, and we have some missing in action - we don't even know where they are. ... We were not prepared for this kind of success, to tell the truth."

    Even though the first launch was successful, he still worries. After all, he's spent $75 million on the project so far, and he intends to spend $500 million before he's done. But to hear him talk, it's not just about the money.

    "I went to bed last night thinking, 'Our baby is up there, 550 kilometers up and probably on the other side of the planet right now,'" he said. "And I'm lying there thinking, 'Gee, I hope she's OK, and I hope we can take care of her.'"

    Right now, Bigelow has just one antenna feeding data to the mission control center for Genesis 1 in North Las Vegas, and he said there's not much time to pull down all the imagery and data Genesis is sending. "We're building two more S-band antennas, one in Hawaii and one in Fairbanks," he said. Bigelow said those should be ready in four or five months - perhaps in time for the Genesis 2 launch, currently scheduled for the November-December time frame.

    Part of the Genesis mission is to find out how long the spacecraft's components can last in the space environment. "We're trying things that are very new, that haven't been flown before," he said. But another part is to learn about orbital life support. That's why Bigelow made an extra effort to place some small-scale life experiments on Genesis 1.

    "We did fly some bugs and some Mexican jumping beans on this flight," he said. Genesis 1's payload also includes an experiment from NASA's Ames Research Center, which was included "as a gesture of good will," Bigelow said.

    Bigelow plans to put ant farms and scorpions on the next flight. "All that sounds kind of irrelevant, but it's actually quite serious," he insisted, "because we're endeavoring to keep things alive, no matter how small, and we have to start somewhere."

    Over the long haul, Bigelow hopes to put increasingly complex critters into space and "have them procreate, have them go into a multigenerational situation."

    In addition to the technological and scientific experiments, there will be financial experiments. "The third mission that we're on is to try to create various business cases, revenue streams that have to do with the general public and these robotic spacecraft, and involve each other through the Internet. Ways of creating entertainment, or games. Advertising."

    The "Fly Your Stuff" promotion is the first example. For this flight, Bigelow Aerospace employees contributed photos and mementos that should be floating around in zero-G, and thus should show up on internal spacecraft images being sent to Earth. The company is currently accepting other people's stuff to be flown on future spacecraft, at less than $300 a pop.

    But don't send anything you'd ever want to have back.

    "This is a one-way trip," Bigelow said. "You can walk out there at night and see the spacecraft and tell somebody next to you, 'I've got such-and-such on that spacecraft right now.'"

    If this first Genesis flight has fired up the imagination for more of those kinds of ideas, that's exactly what Bigelow is aiming for.

    "I would love to get people on board the whole space subject in a grass-roots way that has never been done before," he said. The enthusiastic reaction to this week's initial success is "a step in the right direction," Bigelow added.

    To get this far, Bigelow and his team had to deal not only with the technical difficulties of orbital spaceflight, but with the regulatory difficulties as well. "There was absolutely nothing easy," he recalled.

    The problem wasn't with the Russians: "I cannot say enough good things about the companies that we're working with in Russia," he said. Rather, it's the U.S. government's export restrictions that caused him fits - which should come as no surprise to anyone familiar with the international space industry.

    "We're about the only country in the world that has decided not to commune with the rest of humanity in terms of information about space hardware and space technologies. And I think that's a detriment," he said.

    So how did he find his way through the regulatory thicket? "It was having folks who refused to give up," he said. He had special praise for Bigelow Aerospace's Washington office and the lead attorney there, Mike Gold. The ability to launch in Russia was "thanks to him and his staff and his unrelenting drive to overcome the ITAR regulations."

    Looking ahead, Bigelow plans two launches per year, moving up from the third-scale Genesis to a roughly half-scale prototype, and finally launching the full-scale, 330-cubic-meter Nautilus spacecraft by 2012. The time line targets 2015 for an honest-to-goodness space station, capable of hosting tourists or researchers, performers or athletes.

    Bigelow hopes that the SpaceX Falcon 9 rocket will be ready to go in time for the Nautilus launches. If SpaceX founder Elon Musk is successful, "we are probably a multiple-flight customer for him," Bigelow said. But for now, the converted Russian ICBM - known for commercial use as the Dnepr rocket - is good enough.

    "That rocket will satisfy two generations of spacecraft for us, the Galaxy and the Genesis," Bigelow said. "We will fly numerous times using that vehicle for both generations. If we get to a situation where Elon is not ready, and there's no other domestic rocket on the horizon that is affordable - which is of course the problem today - then yes, we'll probably be looking for a foreign rocket."

    That would likely be a Russian launch vehicle like the Soyuz or the Proton, he said.

    Rick Tumlinson, one of the founders of the Space Frontier Foundation and a veteran rabble-rouser in space circles, said that Bigelow's project could eventually lead to the fulfillment of a decades-old dream. In a congratulatory news release, Tumlinson declared that the Genesis 1 launch was "what the opening of a frontier is all about," and would lead to bigger steps ahead.

    "At the point when we have private transportation going to a private destination in space, history just changed," Tumlinson told me today.

    But Bigelow isn't thinking about the history books just yet. He's still worrying, even after this week's apparent success.

    "We're a small, humble organization, and we make up for our small size with our enthusiasm and the expertise of our crew," he said. "I don't think we want to be overconfident. There is plenty of room for failure. We think this success doesn't preclude that we're going to have failures in the future."

    Bigelow wasn't just being metaphorical about seeing that Genesis spacecraft in the sky. Satellite experts have already worked out a schedule of viewing opportunities - some of which should be bright enough for the naked eye. Go to the Heavens-Above Web site, plug in your coordinates, then go to the satellite database and search for "Genesis-1." You can also go directly to this page to see Genesis' current location, but you won't be able to find out when and where you can see it from the ground.

    This Real Time Satellite Tracking page can also show you the orbital location of Genesis 1 and lots of other spacecraft, including the space shuttle Discovery, which was launched last week ... by that other space program. 

  • Beam my bid up

    Christie's Images Ltd. via AP
    This model of the Starship Enterprise-A, used for visual effects in the film "Star
    Trek VI: The Undiscovered Country," will be among the items put up for auction.


    October's sale of "Star Trek" memorabilia has already touched off a Warp Factor 7 buzz, and the Christie's auction house is hoping that a new online bidding system will boost participation. The system, known as Christie's Live, passed its first test during a home-furnishings auction today - but will the setup be satisfactory for legions of online Trekkers?

    Christie's spokesman Rik Pike admits that the unprecedented Oct. 5-7 auction of "Star Trek" TV and movie props "will be one of the major tests of the rollout" for the new online system, which was developed in league with Florida-based Auction Management Solutions.

    The New York sale involves more than 1,000 lots, comprising about 4,000 items ranging from a non-playable flute used by Captain Picard (estimated value $300) to a model of the Enterprise used in visual effects (valued at up to $25,000). In all, the auction could raise more than $3 million.

    Christie's Live offers a streaming-video window on the sale, plus the capability to enter bids that would be recognized by the auctioneer at the podium. The software interface signals whether your online offer is the high bid.

    "This is like being in the room with an auctioneer," Pike said.

    Would-be online bidders have to register with Christie's at least two business days in advance of the sale, but Pike told me there would be "no set limits" on the number allowed to register for the "Star Trek" sale.

    "The limits will only come down to bandwidth and technological capabilities," Pike said.

    That's different from the situation for today's pilot auction: About 15 clients were selected by Christie's to participate in the test, and according to Pike, the process worked out just fine. The first lot to be won by an online bidder was a Victorian colonial carved hardwood banquette that went for $1,680, well above the estimated price of $800 to $1,200.

    The "Star Trek" sale will serve as the highest-profile test for Christie's Live, but if all goes well, the auction house plans to offer the online option for all its sales next year, Pike said.

    In an e-mail exchange about the upcoming auction, Robert Pearlman, editor of the CollectSpace Web site and an expert on space collectibles, said the online dimension could change the character of the event:

    "I have watched and taken part over the past few years as several 'offline' auction houses that specialize in space memorabilia have gone online with their bidding, and it has added interesting, if not always positive, results to the process.

    "Obviously, the greatest benefit (from the perspective of the auction house at least) is the influx of bidders — bidders who in the past haven't or didn't choose to have the opportunity to participate because of geography, conflicting schedules or even intimidation by the auction house setting.

    "Depending on how the bidding is organized and what software is used to connect the online world to the real-life auction, the introduction of this new audience can sometimes slow the pace of the sale. Unlike in-person or even phone bidding, you can't see or hear if a person is considering a bid, so sometimes you sit waiting for a 'paddle' to pop up on the screen. For the online bidder, this process can also seemed rushed, as again depending on how the sale is presented, it can move at a far greater pace than what they are used to on sites such as eBay.

    "Online bidding can also make an auction a spectator sport, as you can sit back in the relaxed atmosphere of your office or house and watch the sale unfold. You could do this before by going to the auction, but there are issues of available seats and whether the auction house allows such.

    "Which raises another point: As online bidding has grown in popularity and reliability (early software would reportedly fail to register bids or would crash at inopportune times), some auction houses have seen a drop in physical attendance to their sales. Why spend money traveling to a different city (or country) when you could save that dough for the items you're looking to buy?

    "For Christie's, though, their auctions have typically been events unto their themselves, where attendance is part of the fun. At their 1999 first sale of space exploration memorabilia, there were Apollo astronauts in the audience. Not to mention, you had the opportunity to actually view the lots — artifacts — in-person, which besides serving as a mini-museum, can be an advantage to the bidder. A 2-D photo and a description can only do so much before you want to see and hold the actual piece before buying.

    "It is appropriate, however, that one of their first online enabled auctions should be for 'Star Trek' memorabilia. Looking past the lack of any currency in the future Federation of Planets (other than the occasional bar of 'gold-pressed latinum,' that is) one can certainly imagine a distant future where auctions are conducted inter-planet (or at least inter-space vehicle/station). Back to present day, 'Star Trek' has certainly captured the imagination of a worldwide audience, and presuming Christie's will allow registrations from any part of the world, their auction could be a very small model of the future unified-Earth that Gene Roddenberry imagined."

    As long as it's free, I'll sign up for the auction. Who knows, I might see a fake flute I just can't resist. What about you?

  • Guest workers in ancient China

    Archaeology magazine's Mark Rose sends along a link to an interview with the University of Pennsylvania's Victor Mair, about a DNA analysis done on the remains of workers who built the tomb for China's first emperor about 2,200 years ago. "One of them at least was not Chinese!" Rose writes. Researchers say the genetic signature indicates the worker's roots went back to western Eurasia, perhaps Iran.

    Mair says the presence of guest workers in ancient China wouldn't be too surprising. "After all, at this time and even earlier, we've got Iranian peoples - Wusun, Scythians, and others - running all over the Eurasian steppes from the Black Sea to what is now northern China," he's quoted as saying. Nevertheless, the findings open a new frontier for genetic genealogy.

    "I don't think anybody has picked this up," Rose says. Now somebody has.

  • Lights, camera, blastoff!

    Imagery from last week's launch of shuttle Discovery shows that it'd be a real blast to ride on one of the shuttle's solid rocket boosters, each of which packs 1 million pounds of heavy-duty explosives. Video cameras mounted on the boosters, recovered over the weekend, show the whole three-minute rise to separation from the orbiter and its tank - plus the four-minute fall to an Atlantic splashdown. It's must-see NASA TV.

    NASA
    The solid rocket booster's aft camera provided
    this view of the departing shuttle Discovery.


    NASA's space shuttle multimedia gallery links to the video files from the booster on the shuttle's right side. The view from the forward angle (Windows Media) is great for the ride up, showing engine ignition and the rise from NASA's Kennedy Space Center. Prime time for the aft camera comes about three minutes into the clip (Windows Media), when there's an amazing shot showing the shuttle leaving the tank behind.

    The forward camera gives you the best view of the descent, from an altitude of 40 miles all the way to splashdown and beyond, at about the seven-minute mark. Florida Today's Chris Kridler has put together a two-minute condensed version, set to music.

    This isn't the first time we've seen booster-cam video - check out this NBC News video from last year's Discovery launch for a sampling - but since the last mission, additional cameras have been added to the boosters, improving the video angles.

    If you're a space-video jockey, or just a fan of cool cosmic views, our "Liftoff" interactive lets you mix and match views of Discovery's ascent. There's still more video archived at the aforementioned NASA multimedia Web page, as well as in this section of MSNBC's shuttle mission coverage. And stay tuned for real-time video coverage of the current mission's final spacewalk on Wednesday.

    Update for 7:30 p.m. July 12: NBC News' Brian Williams gushed over the booster-cam video during this evening's "Nightly News." Here's the clip.

  • Inflatable space dreams

    It's taken months longer than he hoped, but real-estate billionaire Robert Bigelow might just see his first orbital spacecraft take flight at last on Wednesday, courtesy of a converted Russian intercontinental ballistic missile.

    If Bigelow Aerospace's Genesis 1 inflatable space module lifts off successfully, the test mission could mark a significant step toward an era of hotels and even sports complexes in space.

    An artist's conception shows Bigelow Aerospace's
    Genesis 1 spacecraft after orbital inflation.


    Russia's Federal Space Agency lists Genesis 1 for a Wednesday launch from the Dombarovsky military missile base in southwestern Siberia. This would be the first on-orbit test of Bigelow's inflatable-module concept, which was actually developed at NASA for future space station modules or Mars ships. When NASA canned the concept, which was known as Transhab, Bigelow bought the rights to commercialize the idea - and hired some of the original designers.

    The concept calls for sending up a compressed, soft-sided spacecraft that could be inflated once it's in orbit - sort of like one of those blow-up kiddie play chambers you see at carnivals. Only in this case, the walls are made out of graphite-fiber composite materials that would be tough enough to stand up to encounters with micrometeoroids and orbital debris.

    Such modules would be cheaper to send into space, and allow for larger pressurized volumes once they were inflated. For example, the one-third-scale Genesis prototype is designed to puff up from about 6 feet in diameter to about twice that size. As Bigelow's test program proceeds, the prototypes are supposed to grow larger - ending up in a full-scale Nautilus craft that would enclose 11,650 cubic feet (330 cubic meters), or roughly the volume of a three-bedroom home.

    Bigelow is already floating some ideas for using the test modules a commercial opportunities: The second launch, which could take place in the September-October time frame, could fly photos and mementos into space for less than $300 each. As part of the deal, pictures of the items floating in zero-G - as well as views outside - would be beamed back down to Earth. Bigelow Aerospace's Web site suggests that a space-based bingo game has been under consideration, as well as space art and orbital billboard messages.

    Eventually, space tourism ventures could offer budget accommodations in a Nautilus hotel complex, for far less than the current $20 million going rate for trips to the international space station. And IPX Entertainment's Rocky Persaud has his heart set on using an inflatable module as a venue for zero-G athletics.

    Bigelow's venture might sound like a lot of hot air, but NBC News space analyst James Oberg said in an e-mail that "the idea he is pursuing in his 'venture capitalistic' Wild West style has genuine merits and high future profit potential ... if not for him, for the next consortium that picks up the baton."

    Oberg said the key shortcoming for Bigelow's plan has always been the question of how to provide affordable access to any private facility built in orbit.

    "But two recent trends - the NASA support for commercial space transportation to support the future of the existing space station, and the French-Russian construction of a Soyuz spacecraft launch capability from the equatorial space base at Kourou in French Guiana - promise a potential solution to this shortcoming in the next six to eight years," Oberg wrote.

    In the short term, Bigelow is going with the low-cost Russian launches - and in the longer term, he's planning to use SpaceX's Falcon 9 rocket. A 2008 flight is already listed on SpaceX's launch manifest. Bigelow is also trying to kick-start the orbital options by sponsoring a $50 million America's Space Prize for private-sector orbital spaceships.

    Lots has been written about Bigelow's ambitions: Check out this archived article from Oberg for MSNBC.com, this article from Popular Science, and this from Aviation Week and Spaceflight Now. You'll also find references to the Bigelow plan this week in Technology Review and Flight International. And to keep track of the private-sector space race, you can't do better than Clark Lindsey's RLV and Space Transport News and Jeff Foust's Personal Spaceflight, which both deserve a big tip o' the hat from Cosmic Log.

    Once you've drawn in all these facts and fancies, feel free to weigh in with your comments below.

    Update for 7:05 p.m. July 11: Bigelow Aerospace's Mike Gold says in an e-mail from Russia that the launch may or may not go off on Wednesday. "All I can say right now is we still expect to hit our previously announced launch window of July 4-14."

  • The geometry of music

    The same mathematical principles that physicists use in string theory can be applied to analyze a string quartet, a music theorist writes in this week's issue of the journal Science. He's devised a new geometrical model that just might serve as a "theory of everything," at least when it comes to Western musical traditions.

    The idea of expressing music geometrically goes back centuries. The five-line staffs used in musical notation, for example, can be thought of as grids for plotting the points and curves of a melody. Musicians have looked to the "circle of fifths" as a formula for understanding tonal chord progression since the 1700s. But lots of musical styles lie outside the classical circles, ranging from the chromatic sweep of Wagner to the dissonance of  Schönberg to the fusion of Miles Davis. 

    "There have been lots of geometrical representations of music," Princeton music theorist Dmitri Tymoczko told me today. "It's as if we had maps of many small neighborhoods in a city, but we didn't have a sense of how those maps fit together."

    To try to fit them together, Tymoczko turned to mathematics that's often applied to the problems of extradimensional physics. He visualized music as a lattice of points in a folded-up, symmetrical space known as an orbifold.

    "The mathematical terminiology and technology to do that is only about 50 years old," Tymoczko said. "These spaces, these orbifolds, are familiar to modern string theorists."

    For years, string theorists have used music as a metaphor for fundamental particles, and now Tymoczko is usiing the mathematics of string theory to understand the fundamentals of music.

    The math makes it easier to understand objectively what great musicians and composers do in their head. "When you sit down to interact with a piano, you're actually interacting with a non-Euclidean space, because there are many different ways you can play a C-major chord on a piano," Tymoczko said.

    He said orbifolds capture the multidimensionality of music: how harmony interacts with counterpoint, how chords are connected with each other, even how notes are arranged "to minimize the amount of effort that musicians have to make when moving from chord to chord."

    Princeton
    Points within a tetrahedron
    represent chords from a
    Chopin piano prelude.


    Tymoczko has done up a QuickTime movie of a particularly tricky Chopin piano prelude in E-minor (Opus 28, No. 4) to illustrate how the orbifold works.

    "This prelude is mysterious," he explained in a Princeton news release. "While it uses traditional harmonies, they are connected with nonstandard chord progressions that people have had trouble describing. However, when you plot the chord movement in geometric space, you can see Chopin is moving along very short lines, staying primarily within one region."

    On Tymoczko's Web site, you can find additional resources, including his ChordGeometries software, a version of his Science paper and a series of four QuickTime video files that provide further audiovisual explanation. There's even a QuickTime depiction of the famous chords from Deep Purple's "Smoke on the Water."

    The scheme works less well for musical styles that don't have the Western notion of chord progression. But even for non-Western styles - say, the rhythms of African music - "you can use my geometric model to think about how you evolve from one rhythmic pattern to another."

    Could Tymoczko's geometrical scheme open the way to computer-composed music that might surpass Bach and Beethoven?

    "That's not going to happen," he said. "This isn't going to take anyone from being a mediocre composer to a brilliant composer. But it might help you get from being a beginning composer to a pretty good composer. ... We're going to be able to instruct computers to produce musical results. At the very least, we won't ask computers to do impossible things."

    Tymoczko said he uses his software as a tool when he's writing his own music. Another composer, Michael Gogins, is to present a paper on the application of the orbifold method at the International Computer Music Conference this November in New Orleans.

    Although they may use the same math, the composers have an advantage over the string theorists in at least one respect. String theory has shown that there may be 10500 solutions for the equations that govern the state of the universe, but Tymoczko said "one thing that the spaces show us is that Western music is much more of a unique solution than you might have thought."

    That makes it easier to determine which strings of notes make music, even the dissonant kind, and which are just plain noise.

    "It's better news than the string theorists are dealing with," Tymoczko said.

  • The space station's third man

    NASA TV via AP
    German astronaut Thomas Reiter flashes a smile and a thumbs-up sign for the
    camera Thursday after entering his new home, the international space station.


    German astronaut Thomas Reiter became an official member of the international space station's crew today and started a five-month tour of duty, cooped up with two other guys in the equivalent of a three-bedroom house bristling with cameras and computers. Think "Big Brother" in orbit.

    It may sound like a claustrophobic nightmare in the making, but instead Reiter compares it to a fishing trip. A really, really long fishing trip.

    Reiter's stay on the space station marks several firsts:

    • First time in more than three years that three astronauts have been able to live aboard the station for an extended period of time. After the 2003 Columbia tragedy, the space shuttle fleet was essentially grounded. That meant the space station's crew had to be scaled back to two, because only the shuttle could provide enough supplies for a three-person live-aboard crew.
    • First European astronaut on a station expedition crew - in fact, the first expedition member to represent a country other than the United States or Russia.
    • First station resident scheduled to join one expedition in progress (Expedition 13, with Russia's Pavel Vinogradov and NASA's Jeff Williams) and stay through the transition to a different expedition (Expedition 14, with NASA's Michael Lopez-Alegria and Russia's Mikhail Tyurin due to arrive in September).
    • First European astronaut scheduled to perform a spacewalk from the international space station.

    Reiter, 48, knows what's involved in a long-distance stay: He spent six months aboard Russia's Mir space station in 1995-1996, conducting a spacewalk during that stint. That whetted his appetite for another turn at living in space, he told NBC News during a pre-launch interview:

    "We know the sensation of [zero] gravity is just fantastic. Once you've adapted to it, to use the available space in all three dimensions is something very great. The beautiful view toward the earth, or in the opposite direction ... those are things that come together. I can relate to that now, going on the next mission. And I think everyone who has been in space is infected by all these sensations, all these impressions and experiences, and is longing to get back. So am I."

    The smile on Reiter's face as he floated into the space station today showed how thoroughly he has been infected by the space bug - but there are less pleasant side effects as well. Reiter and his wife have two boys in school in Germany, and he admitted that the separation from family - for training as well as for the mission itself - is a hardship. "I've been away from home for almost two years now," he said.

    He takes a philosophical stance toward that aspect of the job:

    "I try to relate it to other professions. We are living in the north of Germany at the moment, close to the shore where a lot of families are actually in a very similar situation, because people are going to sea on fish trawlers, and they are sometimes gone for the same time. So in this respect there are no big differences. We are in a little bit more exposed location, and the circumstances are a little bit more unique. But I think if we take that all together, my family is, hopefully, as well-prepared as I am."

    Reiter won't exactly be on a fishing trip. In addition to the spacewalk and other maintenance chores, he'll be working on an agenda of 19 scientific experiments for the European Space Agency's Astrolab program - and blazing a trail for the ESA's Columbus laboratory module, which is to be added to the station in September 2007:

    "We will use this opportunity to prepare our specialists, or flight controllers, for the moment when Columbus is up, and hopefully then they can get in an operational state in a much shorter time, having this experience now."

    The addition of Reiter to the Expedition 13 crew became official when his custom-fitted seat liner was transferred from the shuttle to the station's Soyuz escape capsule. That's the traditional transition time because Reiter's nearly 6-foot (182-centimeter) frame will need that cushioning if he has to ride the Soyuz back down to Earth.

    When will the earthward ride come? The answer to that question is a bit, well, up in the air. If the shuttle schedule holds, NASA astronaut Sunita Williams would fly up to the station as part of the STS-116 shuttle crew in December and replace Reiter, who in turn would take Williams' place on the outbound shuttle.

    If STS-116 is delayed for some reason, Reiter's stay in space would be extended - either until the shuttle flew, or until another Russian Soyuz craft brought Expedition 15 up in March or so. Then Reiter would take a Russian taxi home, and get the chance to use that Soyuz seat liner.

    On the subject of an extended stay, Reiter was once again philosophical:

    "This is always something you need to consider when you are going on a long-term mission. It might not be exactly five or six months. It could be a little more."

  • Sources of space sights

    Every time we run a "Month in Space" roundup of cosmic images, we get e-mail from readers asking where they can see the original, downloadable pictures that were adapted for the slideshow. So here's a list of links to further details about the images, plus bigger versions.

  • To the stars!

    The X Prize Foundation is working to bring regular folks up to the edge of space, NASA is aiming for the moon, and the Mars Society is pushing for trips to the Red Planet. So who's focusing on the incredibly far frontier beyond the solar system? Scientists and dreamers from NASA and elsewhere have established a new foundation to focus on the real-life prospects for interstellar flight.

    The Tau Zero Foundation, which takes its name from Poul Anderson's science-fiction novel about a near-speed-of-light odyssey, focuses on the subject of "practical starflight." Here's a description of the group's mission from one of its founding fathers, Marc Millis, who keeps tabs on breakthrough propulsion physics at NASA's Glenn Research Center:

    "The Tau Zero Foundation will establish itself as the dependable venue through which the visionary goals of interstellar flight can be advanced through imagination coupled with intellectual rigor. The allure of undiscovered breakthroughs will be used to inspire and educate the public, and in turn, these educational ventures will promote the Foundation. To advance science and technology, the Foundation will channel financial support to credible risk-takers within legitimate establishments, selected largely through competitive processes. To stay poised for capitalizing on ancillary benefits, the most promising developments will be aimed toward revenue-generating products and services."

    In a follow-up comment, Millis talks about the range of technologies to be studied:

    "The strategy of the Foundation will be to cover the whole span of ambitions, but with cycles of short-term, affordable investigations that target the most important questions. This span includes the seemingly simple concept of solar sails to the seemingly impossible goal of faster-than-light travel, to hedge the bets."

    As Millis relates in his manifesto, the foundation draws together a variety of scientists, engineers and authors who have delved into the facts and fiction surrounding interstellar flight. Several work at NASA, a couple work at Edwards Air Force Base, and others come from familiar corners of the aerospace industry.

    The organization's charter contains a call for philanthropic backing, based on the model set by the SETI Institute (which was a hit) and the Biosphere 2 project (which didn't quite work out the way its founder planned).

    Millis draws a sharp line between his work at NASA and his interest in the nascent foundation - so much so that he declines to discuss the foundation from his desk at Glenn Research Center. However, Millis says there's plenty to talk about from the NASA side of things, even though funding for his Breakthrough Propulsion Physics Project was discontinued in 2002.

    "My center is covering my time on the center's overhead to maintain awareness of the project, keep up on the research and publish assessments as things come up," Millis told me last week.

    In a recent assessment, published by the Annals of the New York Academy of Sciences, Millis looks at way-out ideas ranging from antigravity (not viable, Millis says) to the Woodward effect (unresolved) to faster-than-light travel (a candidate for future research). Here's a PDF version of the paper published by NASA.

    At one time, NASA itself conducted some research into a purported antigravity phenomenon known as the Podkletnov effect, but Millis said that's now pretty much a dead issue as far as he's concerned. He pointed to later research that found "no evidence of a gravity-like force" using an apparatus that would have been 50 times more sensitive than the original Podkletnov device.

    Millis is more interested in research into the Woodward effect - "a transient inertia effect" that could eventually have implications for propulsion, if verified - as well as a more recent study of "a fairly large gravitomagnetic effect, too large to be explained with general relativity as we understand it so far."

    He cautioned that "we're not talking about an immediate propulsive effect, and it might be a measuring artifact." But at least the research illustrates that there are still mysteries out there that could someday turn those science-fiction dreams into practical starflight.

    "The bottom line," Millis said, "is that there are no breakthroughs that appear imminent, but there are definitely small steps that can be taken to continue to look into these things."

    Is this all pure moonbeam stuff, or are there hints of practicality to way-out concepts such as the hyperspace drive? Feel free to weigh in with your comments below.

  • Snake eye saves the day

    NASA Micro Inspection Team's Brad Smith, Jeff Rowell and Charles Wassen 
    demonstrate how they used a fiber-optic, high-definition camera to inspect the area
    where foam fell off a bracket attached to Discovery's external tank.


    It might not be a giant leap on the order of the duct-tape contraption that helped save Apollo 13, but a snake-eyed camera used by launch-pad inspectors helped NASA take one small step toward the shuttle Discovery's launch on Independence Day.

    The problem came to light on Monday after inspectors found that a fleck of foam insulation had fallen off a bracket high up on the shuttle's external fuel tank. One of the things mission managers needed to do was get reassurances that there wasn't further damage to the foam in a nook or cranny that couldn't be seen from their vantage point.

    If workers had to erect scaffolding for a "hands-on" inspection, that would have set back the launch schedule at least a day - missing July 4.

    It's not so much that NASA was desperate for a Fourth of July launch, even though John Shannon, the mission management team's chairman, said such a fireworks display would be a "great gift" to the nation. Rather, Independence Day offered the best weather for launch, and NASA didn't want to miss that opportunity.

    Bill Gerstenmaier, NASA's associate administrator for space operations, said the Micro Inspection Team offered to use a contraption that had been cobbled together from an off-the-shelf boroscope camera and a flexible, 8-foot-long aluminum tube wrapped in plastic inside and out. The tiny camera, mounted on the end of a cable reel, was snaked through the tube - and the tube could be curled into curves to go around an obstructing feedline on Discovery's tank.

    "The ground ops team came to the rescue here with just a great inspection technique that allowed us to really get a good close look at this," Gerstenmaier told reporters Monday night. "They knew where the access was, what they could get to, and they knew what they had to look around and they knew they had the technique, so they just did a great job of coming up with this idea."

    The Micro Inspection Team's pictures showed that the hard-to-see areas of the tank were undamaged.

    Today, team members said they've been using the setup for years - but this was the first time it was used to peek around obstructions on a shuttle fuel tank.

    "We find new ways each day to utilize this for specialized techniques," Charles Wassen told reporters.

    Jeff Rowell was one of the guys who poked the snake eye around the tank. "We were fully extended, plus all of my arm," he said. The resolution was more than good enough to spot any damage, he said.

    "As close as you can get it, it's about like looking at it with your eyeball," Rowell said.

    He estimated the cost of the makeshift device at $50,000 to $60,000 - with most of that money tied up in the high-tech boroscope camera plus. That's not bad, considering that the cost of a holiday launch postponement is in the neighborhood of $1 million.
