Senate and House pass bills for future of NASA
July 22, 2010
The Senate and the House of Representatives have both passed their own versions of Obama’s proposed budget for NASA. As I’ve mentioned here before, Obama’s plan to abandon the Constellation program and leave American access to low earth orbit in the hands of the private sector was met with a good bit of criticism, both from Republicans and Democrats alike. Though I supported (and still support) his initial plan, I figured we would end up with some sort of compromise in the end. Not surprisingly, that’s where we’re headed now that the Senate and House versions have come out. I don’t have the time nor the willpower to type out the gritty details of the differences, but in a nutshell, the Senate wants to extend the space shuttle by another mission or two, slash funding for commercial space companies in half, accelerate the development of a heavy-lift rocket based on current shuttle booster technology, and slash funding of research into advanced technologies. For a more detailed comparison between Obama’s plan and the Senate plan, check out this article on Universe Today.
The House plan, which was issue by the House Science and Technology Committee (chaired by TN’s own Bart Gordon) is even worse. They want to slash funding for development of commercial access to low earth orbit by MUCH more than the Senate version, and like the Senate they want to speed up development of a heavy-lift rocket. The biggest problem is that the House version essentially brings back Constellation. For more detailed info on the House version, check out this article on Space.com.
I’m by no means a politician or an economics expert, but I’m firm in my belief that if NASA keeps focusing money and effort on access to LEO/the ISS, then we are spinning our wheels and making no progress. NASA cannot keep funding and worrying about getting our astronauts to and from the ISS AND worry about/fund our exploration into the rest of the solar system at the same time.
NASA updates/Chile earthquake shortens day length
March 2, 2010
It’s been a minute since I mentioned the NASA budget/direction controversy, so here’s a bit of an update:
Lots of NASA employees and contractors in the vicinity of Cape Canaveral have launched a campaign against Obama’s budget cuts/change of direction for NASA. They are doing this because when the shuttle program winds down later this year, and the Constellation program gets ousted altogether, there won’t be nearly as many jobs in the area. That’s a legitimate concern, but in the big picture, I say it’s a necessary evil. Besides, these people are engineers, scientists, etc… they are all very smart and quite capable of finding work in other areas, maybe even for the private companies like SpaceX that will take over the duties of getting cargo and astronauts to the International Space Station. I am all for Obama’s plan, because it pushes NASA to look ahead into exploring the rest of our solar system. That’s where the REAL science/discoveries happen. In reality the space shuttle is a dinosaur- it’s expensive to maintain, and it’s not safe. It has no bailout system whatsoever, so if something goes wrong (see: Challenger and Columbia), the astronauts inside are screwed. It is most definitely an impressive piece of engineering, but it’s time to move on. NASA can NOT continue spinning its wheels, never getting us past the ISS and/or low Earth orbit. NASA needs to focus its efforts/money on projects like the VASIMR plasma rocket engine, which could cut a spacecraft’s trip to Mars from 6 months to roughly 40 days. The new commercial spaceflight companies will be more than capable of handling NASA’s cargo and low Earth orbit needs much sooner than NASA could on its own via the Constellation program. End of rant.
In some happier science news, Google is developing a new thermal mirror energy system that could cut the cost of electricity to 5 cents per kWh. This would make solar thermal energy much cheaper than coal. These stations are made up of a huge array of mirrors arranged so that they create one gigantic parabolic mirror. The parabolic shape reflects all the sunlight into one point, at which a heat-collecting device is mounted (on top of a tower), which in turn heats water into steam that runs a turbine to generate power. Naturally this system is only good for areas which receive a lot of sunlight such as deserts, but if Google can make them cheap to build, they could play a big part in getting the world weened off of fossil fuels for energy production. As I’ve said before, we shouldn’t be fiddling with ways to cleanup our use of fossil fuels, we should be focusing eliminating our dependence on them altogether. (Via EcoGeek)
Finally, the earthquake that rocked Chile over the weekend may have actually shortened the length of a day. Granted the current estimate is that our day was shortened by only 1.26 milliseconds, but that’s still pretty amazing. Not only did the day shorten, but the figure axis was also offset by about 3 inches. Think of how big this planet is… that earthquake had to release an unfathomable amount of energy to actually alter its axis! (Via Space.com)
Snowpocalypse: Part Duex/NASA rumors
January 28, 2010
Here we go again. I recommend investing in Kroger stock this year, because they’re gonna get a big boost in sales in TN from all these “snowstorms” wherein a meteorologist utters the word “snow” and 75% of the population immediately clears the milk, bread, and egg isles. (Apparently people only eat french toast during snowstorms?) As usual, I’ve been monitoring the progress of the forecast and find it interesting that the NWS hasn’t issued the winter storm warning yet, only a watch. I’m sure the warning will come, but it’s kinda funny that they’re hesitating, no doubt because of the giant snow fail from a few weeks ago. (To be fair, some areas around the midstate did get something close to the forecasted amounts, though no one really got the full 2-3 inches that was initially forecast…) This system is a little different than the last one, however. This one will most definitely have enough moisture to generate the 3-5 inches, unlike the last system which had moisture “issues.” The big limiting factor with this system will instead be temperatures. Nashville will literally be right on the dividing line between having an ice/rain mix and having an all snow event. If this system decides to track just 50 to 100 miles further north than the models think it will, that will cause more warm air to advect farther north, and we’ll end up having mostly rain friday changing to a little snow on the backside fri. night into sat. morning. If it decides to track slightly further south, we’ll have all snow, but much less of it, and areas to the south of us could actually see more snow than Nashville does. This system has a little better chance of “success” in giving us a good ol’ fashioned snowfall than the last one, but I wouldn’t place any bets yet.
Big rumors abound in the blogosphere about Obama’s budget proposal due to land in Congress on Monday. The biggest rumor is that it will completely cutout NASA’s Constellation program, which is the rocket system currently under development to not only replace the Space Shuttle, but also put men back on the Moon. I reported many times on the progress of the Augustine Commission and its recommendations for how NASA should proceed given that its current “trajectory” was financially unsustainable. One of the options they proposed was to eliminate the Constellation program and let commercial spaceflight companies like SpaceX takeover the duties of getting astronauts to the International Space Station and other low-earth orbit missions. I have a feeling that if the budget really does cut the Constellation funds, that’s where we’ll be headed next. Honestly I think it may not be a bad idea, because it would allow NASA to focus more on getting man further out into the solar system, and eventually to Mars. I tend to agree with Dr. Phil Plait’s (the Bad Astronomer) sentiments on the issue (as usual) but I’m not in total agreement with him that we should still go back to the moon. But then again, he’s the astronomer with a Ph.D and I’m not. For even more info, check out Universe Today. Check those blogs again on Monday afternoon, as I’d say they’ll be able to update waaaay sooner than I will once the actual budget info is released.
Bizarre balloon-rocket moon mission/Gibson gets raided by the Feds
November 18, 2009
Two cool things come your way via Universe Today today:
Apparently a Romanian group is competing for the Google Lunar X-prize with a bizarre balloon-rocket combination. They have a nice animation video in the post that explains the design far better than I could with word, so just check it out for yourself. I never thought I’d see helium balloons involved in a project where getting to the moon is the final goal… It’s one of those things that’s mind-numbingly simple and you say “why did no one think of this before?”
Also from UT is this cool HD video of Space Shuttle Atlantis blasting off on Monday. The shuttle docked today with the ISS.
Regarding the Feds’ raid of Gibson HQ yesterday: (FYI- it wasn’t the FBI, it was the Fish & Wildlife Agency that raided them…)

The floodgates of exoplanet discovery just opened. The High-Accuracy Radial Velocity Planet Searcher (known as HARPS) discovered a batch of 32 new exoplanets, pushing the list of known exoplanets to over 400. Most of these are low-mass planets about the size of Neptune. Since HARPS (which is a spectrograph) works with a land-based telescope which has to put up with the distortions and aberrations of the Earth’s atmosphere, that’s a very impressive feat. It shows just how good astronomers are getting at planet-hunting, and with the recently-deployed Kepler space observatory working like a charm, it won’t be long before we find the jackpot of astronomy to date: an Earth-like planet orbiting a distant star.

I’ve mentioned that new theories challenging the textbook theory of a massive asteroid impact in Mexico killing off the dinosaurs are gaining serious momentum in the field of paleontology. The main challenge to the impact theory is the one involving a massive, long-erupting supervolcano in India known as the Deccan Traps. India has coughed up yet another, 3rd challenge to the impact theory: an impact event of its own. Some researchers from Texas Tech University think that a huge depression that exists beneath part of the Indian Ocean is actually an impact crater, and that it’s the result of an asteroid that smacked into the earth near the time the dinosaurs went extinct. (In geologic terms “near” actually means within a few million years…) If this turns out to be a true crater, and not just the result of normal tectonic plate movements or volcanic activity, then I’d say it definitely had at least some effect on the dinosaurs, and probably some effect on the ongoing eruption of the Deccan Traps.

NASA rolled out the first full sized test vehicle for its new Constellation program earlier this week. The Ares I-X was rolled out to launch pad 39B for its scheduled test flight next week on Oct. 27th. This is a full-scale mock-up of the Ares I, which (if the current plan is adhered to) will replace the Space Shuttle as NASA’s method of delivering astronauts to and from low Earth orbit. The test flight, of course, will be unmanned. Here’s a pic via NASA’s website. Keep up with the test launch at the launch blog. The new rocket is 327 feet tall, over 100 feet taller than the Space Shuttle.

I also found on UT the final explanation of the Google UFO logo that caused quite a stir yesterday all over the interwebz. The Google tech-nerds were simply showing some love for the Japanese video game Zero Wing, the one with the famous quote “All your base are belong to us” at the beginning. Google also tweeted a mysterious set of numbers. It turns out if you insert the corresponding letters of the alphabet, you get “All your O are belong to us.” No, Google doesn’t know something we don’t. No, it wasn’t a hint that we’ll soon be visited by aliens, or that the government will finally come clean on a huge conspiracy theory. Sorry, Fox Mulder.
Until this morning I’d never heard of EEStor, but this new technology could revolutionize…. everything. But apparently it’s been met with quite a bit of skepticism. Basically it’s a new way of storing electricity, much more efficient than a lithium ion battery, and it would make storage of power generated by wind turbines and solar cell arrays much easier. The problem with power from the wind and sun is that it isn’t constant, therefore you need a way to store that power so that it can be used at all times, even when it’s dark or there’s no wind. That storage has been a big hurdle for the progress of these types of energy. Basically what they’ve done is invent a capacitor capable of storing much more energy than any capacitor before. It was once thought that basic problems with the very laws of physics prevented the development of capacitors with this much storage potential. But apparently this company has managed to convince the Zenn motor company, along with several investors with deep pockets, that they have found a way around those problems. If they’re really on to something it could make 100% green, sustainable power much closer to reality.

Chicxulub challenges/rocket fuel made of ice/eclectic astronauts
August 24, 2009
The theory that the dinosaurs were wiped out from an asteroid impact near the modern-day Yucatan Peninsula is beginning to face major challenges. There’s no doubt that a huge impact caused the Chicxculub Crater, but some recent findings suggest that the impact may have occurred some 300,000 years earlier than originally thought. This comes as a second blow to the impact theory, with the first being the discovery/dating of the Deccan Traps in India. This gigantic volcanic feature is the result of a huge eruption that is believed to have lasted around 30,000 years. Can you imagine a massive volcano erupting for 30,000 years and covering an area equivalent to 1/2 of modern India with lava? Trust me, something on that scale is hard for the human mind to comprehend, but that much volcanic ash and gas in the atmosphere would’ve had a devastating effect on the ecosystem, and almost certainly played a major role in the extinction of the dinosaurs. Get ready for science textbooks to be re-written, because the asteroid impact theory is about to see the same fate as the dinosaurs themselves. (Via Daily Galaxy)
NASA recently teamed up with the Air Force Office of Scientific Research to test a new, Earth-friendly type of solid rocket fuel. I’m not exactly sure of the details, but somehow they’ve managed to make rocket fuel out of aluminum powder and ice. Yes ice… as in frozen water. The secret apparently is that the aluminum powder is so finely ground that it’s considered “nanoscale.” The nanoscale aluminum has so much surface area in contact with the water ice that the exothermic reaction when it burns is more efficient than normal solid rocket fuel, which is usually powdered aluminum (not nanoscale) mixed with an oxidizer such as ammonium perchlorate and a binding agent. Seriously though, who would’ve ever thought you could make rocket fuel out of ice and aluminum? It just sounds crazy, but it’s true. (Via EurekAlert)
When you think of the type of person who becomes an astronaut, you don’t typically think of race car drivers or musicians, but two of the astronauts about to launch on Space Shuttle Discovery tomorrow morning are just that- a former off-road truck racer and a drummer. Check out this Space.com article to find out more about Commander Rick Struckrow, formerly a Baja off-road race driver, Pilot Kevin Ford who is also a drummer, and several other astronauts who come from surprising backgrounds.
Space Underwear/new state of matter
July 29, 2009
Remember Star Trek IV? That was the movie where they ended up time traveling back to the 20th Century and got stuck there, needing some transparent Aluminum to create a holding tank for a humpback whale. Some scientists have now created just that, if only for about 40 femtoseconds. They say it’s an entirely new state of matter, because they used a high-powered laser to remove one of the core electrons from each atom in a tiny area of Aluminum. This allowed X-ray and ultraviolet radiation to pass through uninhibited, effectively making the Aluminum transparent. (Via LiveScience)
Astronaut Koichi Wakata
There are many common luxuries that we take for granted on Earth, such as being able to wash our clothes. Unfortunately, in space you don’t have that luxury. Just going to the bathroom requires a highly sophisticated and technologically advanced toilet system. When astronauts wash their bodies they use special soap and shampoo that doesn’t require water. But in a microgravity environment where droplets of water can float around and destroy sensitive equipment, washing their clothes just isn’t an option. Unfortunately dirty clothes must be simply discarded. But apparently some Japanese scientists are working to fix that by inventing clothes that clean themselves… or don’t get dirty in the first place, depending on how you look at it. Astronaut Koichi Wakata, who just left the ISS on Endeavour, tested these new clothes during his 4 1/2 moth stay. It sounds utterly disgusting, but he never changed his underwear while he was there. The high-tech material actually kills odor-causing bacteria and absorbs moisture. He says that even after 4 1/2 moths of wear, they didn’t smell at all. This is yet another great example of how manned space exploration drives innovation and ultimately leads to technologies that are very applicable here on the ground. This could one day lead to clothes that literally clean themselves, eliminating the need for washing machines and dryers, which are energy and water hogs. (Via Universe Today)
In a related note, Universe Today also posted a set of great photos from Endeavour’s mission. Check it out.
That’s all I have time for today!
Shuttle Mission update/new Apple tablet/Life on Venus?
July 28, 2009
I agree with Yewknee- Day. Made.
Ok, now that you’ve been properly entertained by that photograph thanks to Yewknee’d, let’s get on with the good stuff.
Rumors have been spreading like wildfire for months that Apple will be releasing a new tablet device that could revolutionize mobile entertainment. According to this article on Financial Times, (via Kottke) it’s looking like the device will be released this fall, just in time for the Holiday shopping season. If this thing is as good as it sounds, Apple’s REALLY gonna cash in, and if it flops, their public image will be severely tarnished. But I have no doubt they will succeed with this in the same way they succeeded with the iPhone, save for that minor pricing debacle when it first came out. It seems to me that this thing will be an iPod Touch on steroids. Having just bought a new Macbook Pro, I sure as hell won’t be able to cough up the cash for one of these, but I can’t wait to go play with them at the Apple Store!
Space Shuttle Endeavour undocked from the ISS today after successfully installing the newest Japanese component. The shuttle is scheduled to land at the Kennedy Space Center this Friday at 10:47am EDT, weather permitting. (Via Space.com)
There’s been a lot of speculation about the possibility of life on Mars and more recently, life on Saturn’s moons Titan and Enceladus, and Jupiter’s moon Europa. But not since the 50’s have we ever thought that life could exist on Venus. People used to think Venus might have a climate somewhat like a tropical paradise, but that notion came to a screeching halt when scientists discovered that its surface is basically a good approximation of hell. Its surface temperature is over 860 degrees Fahrenheit, the atmospheric pressure is 92 times greater than Earth’s and made of mostly CO2 and laden with sulfuric acid clouds. But recent research has shown that it’s possible that microbial life could thrive in conditions found in the upper atmosphere of Venus. We continually discover life in places on Earth once thought to be utterly inhospitable, so it’s no longer such a stretch to imagine life surviving in such extreme environments as are found in Venus’ upper atmosphere. Scientists think that Venus was once much more Earth-like, and even had oceans. But what’s commonly referred to as a “runaway greenhouse effect” took over and caused the planet to heat up enough to boil away all water on the surface and create the hellish environment we see today. It’s possible that primitive life may have emerged during the planet’s more hospitable past and had time to evolve, adapt, and escape to the planet’s outer atmosphere where it could survive.
