Forget about jetpacks or flying cars. How about your own personal stealth aircraft? NASA has unveiled the Puffin, an experimental electrically propelled, super-quiet, tilt-rotor, hover-capable one-man aircraft. According to Scientific American, the 3.7-meter-long, 4.1-meter-wingspan craft is designed with lightweight carbon-fiber composites to weigh in at 135 kilograms (not including 45 kilograms of rechargeable lithium phosphate batteries.) The Puffin can cruise at 240 kilometers per hour, but for those high speed chases, can zoom at more than 480 kph. See video below.
Since it doesn’t have an air-breathing engine, the Puffin is not limited by thin air. So, basically, it doesn’t have a flight ceiling. The designers say it could go up to about 9,150 meters before its energy runs low enough to drive it to descend. With current state-of-the-art batteries, it has a range of just 80 kilometers if cruising, “but many researchers are proposing a tripling of current battery energy densities in the next five to seven years, so we could see a range of 240 to 320 kilometers by 2017,” says researcher Mark Moore, an aerospace engineer at NASA’s Langley Research Center in Hampton, Va. He and his colleagues unveiled the Puffin design on January 20, 2010 at an American Helicopter Society meeting in San Francisco.
For takeoff and landing, the Puffin stands upright. But during flight the whole aircraft pitches forward, putting the the pilot in the prone position, like in a hang glider.
Of course, the original idea for this personal aircraft is for covert military operations. But if they can design them safe enough and cheap enough, everyone will want one. It could change our ideas about electric propulsion and personal aircraft.
By March, the researchers plan on finishing a one third–size, hover-capable Puffin demonstrator, and in the three months following that they will begin investigating how well it transitions from cruise to hover flight.
To get something into space right now, you need a rocket. You also need a lot of money, as the current going rate for getting something into orbit is about $5,000 a pound ($11,000 per kg). But what if you could, instead, do away with the rocket and still get your payload to space, for under $1,000 a pound? Sounds like a deal, right.
According to Dr. John Hunter, a physicist at Lawrence Livermore National Laboratory and president of the company Quicklaunch, Inc., using a hydrogen-powered cannon may be the ticket for cheap access to space. That’s right, a “space gun” platform for inserting satellites, fuel, and other supplies into space genuinely could be the next big thing in space technology.
You might say, “A gun to shoot stuff into space? That sounds like something out of Jules Verne!” And you’d be right: in Verne’s “From the Earth to the Moon” a giant cannon called the Columbiad was used to propel three of the characters in the story to the Moon.
“Jules Verne got it right, he just had to pick the correct fluid, ” Hunter said in a Google Techtalk, embedded below.
Rockets have been the workhorse of space-faring nations for decades, but there are a few newcomers to the game that are just getting started. Space elevators are starting to get “off the ground”, so to speak – the Space Elevator Games turned out a winner just last year – as an alternative method of transporting materials into space.
“We do hear about space elevators a lot of the time, and people always ask, ‘Are you related to space elevators?’, but we don’t interact as far as technologies go.” Hunter said.
Light-gas cannons work almost like you’d expect a really, really big gun to work: at one end inside of a long tube a gas, hydrogen, helium or methane, is pressurized to an extreme pressure, 15,000 PSI in the largest cannon proposed by Hunter. The payload is at this end of the cannon, when the pressure is released, the bullet-shaped projectile that holds the payload is ejected out of the end. Hydrogen is used because of its lightness. Since a projectile can’t go faster than what’s pushing it along inside a cannon, the lighter gas – which can travel quicker – allows for a projectile to be accelerated to incredible speeds, in excess of 13,000 miles per hour (21,000 km/hr).
These cannons have been around since the 1960s, though they haven’t seen any use in space payload delivery technology. The record setting cannon for altitude of a projectile was the High-Altitude Research Project (HARP) cannon. It was built by the United States Department of Defense and Canada’s Department of National Defence, and placed in the Yuma proving grounds in Arizona. It successfully lobbed a Martlet-2C inert projectile to 180 km (112 miles) on November 12th, 1966, which still stands as the altitude record for this type of gun.
Another iteration, developed by Dr. Hunter himself, was the Super High-Altitude Research Project (SHARP, an homage to the original cannon) in the late 1980s by Lawrence Livermore University.
Hunter explained to Universe Today via phone interview, “So here’s what happens: I started back in 1985 at Livermore and I was fresh out of grad school and they hired me to build electric guns which I could have done pretty straightforwardly. But I ran into a guy at a cocktail party, believe it or not. He knew I was working on post-production coil guns and and he said, ‘John, those are great because you can get 12km/s where we can only get to like 9 km/s with these gas guns.’ I said, ‘What’s a gas gun?’ That’s what started this whole ball rolling. As it turns out, the electric guns only get to 5.5 km/s and gas guns get to 11km/s.”
SHARP was – and still is – owned by the United States Air Force. Hunter’s company has a five-year contract to utilize the gun for testing shots, but it’s not set up to do shots vertically. SHARP was originally designed as a testbed for hypersonic engines for scramjets – jets that are accelerated to high speeds, then use a specialized engine of their own to push up to 8 or 9 times the speed of sound.
“If we’re going to to a publicized shot, where there’s a lot of publicity and stuff, we’d have to go to a different system, which would not be a big deal to build one because I could dedicate it for that particular application. If we decide to do the shot with the Air Force, that’ll probably be a smaller subset of people who could watch the shot. The Air Force is sorta careful how they do things so we have to get approval. They actually own the gun.”
So Hunter has struck out on his own to develop a commercially viable cannon that can deliver payloads at a fraction of the cost of conventional rockets. He and two other scientists, Dr. Harry Cartland and Dr. Rick Twogood, formed Quicklaunch, Inc.
“We got out of the blocks the 30th of September when we had the Space Investment Summit. Then I made the talk at Google and then the Popular Science article and we have now briefed a venture capital group. We’re in the “hustle phase” and I expect us to be in this hustle phase for six months, where we have to go just shop our project around. But while we’re in this phase we still believe in hardware so I’m actually going to have a demonstrating submerged version late February. It basically will acquire the right inclination and do shots. It’s going to be a 10-foot prototype,” Hunter said.
Ultimately, Hunter envisions a large-scale cannon that will launch from the sea near the equator. In launching from the sea, the gun will be able to pivot and swing around to launch payloads to different orbits easily. Being near the equator is necessary because that’s where the Earth is spinning its fastest, so objects launched from equatorial latitude can obtain a higher orbit with less energy.
Critical to getting the payloads into orbit is the use of a single-stage rocket attached to the payload projectile. Since the largest gun is projected to get the package going at a little over 7km/s (4.3 miles/s), a booster is needed for that extra push to get it past the escape velocity of the Earth, which is 11.2 km/s (6.95 miles/s).
Don’t expect to see humans launching to the Moon or Mars aboard one of the projectiles, though, as the force of launch from the cannon could be up to 5,000 Gs.
The largest – and most expensive – cannon would be capable of launching 1,000-pound (454 kg) payloads into a Low-Earth Orbit (LEO). The projected cost for this cannon is $500 million, but this is the last stage in a proposed series of cannons that would start out small and build on the lessons learned from each iteration.
After some initial testing with the SHARP gun and prototype models, a system that is capable of launching 2-pound (0.9 kg) payloads into space will be designed. The cost of this cannon, Hunter estimates, will be around $10 million and take two years to get rolling.
“[The 2lb capability launcher] is actually tailored to a small niche, which is the Cubesat community. It makes sense because we can “G-harden” cubesats. To me, that would make a nice niche to be able to work with academics. That’ll be a lot of fun because they’ll be orbiting Cubesats, obviously. In Phase one we’re just going to feed inert rounds, and we’re just going to do maybe 20 shots into low space and break the world record ten or twelve times. In phase two we’ll be orbiting things that will take data and will transmit,” Hunter said.
Cubesats – small satellites that are no larger than a liter volume (10cm cube) and weigh less than a kilogram – can be easily “G-hardened”, or made to withstand the impressive forces of being launched out of a huge cannon.
After this system has been tested, Hunter said, “The first commercial system is going to be a $50 million system for 100-pound [45 kg] capability. $50 million is less than the price of an F-15, basically. I think that’s quite within a lot of folks’ means, particularly if you’ve demonstrated phases one and two before that.”
Don’t get Hunter wrong: $50 million is not within the means of the average Joe, but for launching small satellites into space that’s a pretty small number. Each space shuttle mission, for example, costs $450 million, and to launch a communications satellite you’re talking $50 million to $400 million.
The largest gun – 1.1km in length – would run about $500 million and would be able to be constructed within seven years, optimally. Given that the gun itself is reusable, and that capturing the hydrogen from each firing of the gun could be done to save on fuel costs, the cost for somebody wishing to launch a payload would range between $250-$1000 per pound.
Hunter has already seen interest from various enterprises, he said.
“There has been one private company that will remain confidential. We’re going to keep them private until the smoke clears here. We’ve had serious interest from some people. We intend to increase that number of candidates substantially. We’re going to have more candidates than the last republican convention, that’s my goal!”
With regards to whether or not this type of system has had any interest from the R&D over at NASA, Hunter replied, “We have not approached NASA, and I think NASA is ultimately going to become a client of ours…I’m going to be approaching NASA in the next couple of weeks.”
For more about the specific details of the gun and payload deliver system, watch the Google Techtalk embedded above, or listen to the January 15th episode of The Space Show, on which Hunter appeared as a guest.
The new joint Mars exploration program of NASA and ESA is quickly pushing forward to implement an agreed upon framework to construct an ambitious new generation of red planet orbiters and landers starting with the 2016 and 2018 launch windows.
The European-led ExoMars Trace Gas Mission Orbiter (TGM) has been selected as the first spacecraft of the joint initiative and is set to launch in January 2016 aboard a NASA supplied Atlas 5 rocket for a 9 month cruise to Mars. The purpose is to study trace gases in the martian atmosphere, in particular the sources and concentration of methane which has significant biological implications. Variable amounts of methane have been detected by a martian orbiter and ground based telescopes on earth. The orbiter will likely be accompanied by a small static lander provided by ESA and dubbed the Entry, Descent and Landing Demonstrator Module (EDM).
The NASA Mars Program is shifting its science strategy to coincide with the new joint venture with ESA and also to build upon recent discoveries from the current international fleet of martian orbiters and surface explorers Spirit, Opportunity and Phoenix (see my earlier mars mosaics). Doug McCuiston, NASA’s director of Mars Exploration at NASA HQ told me in an interview that, “NASA is progressing quickly from ‘Follow the Water’ through assessing habitability and on to a theme of ‘Seeking the Signs of Life’. Looking directly for life is probably a needle in the haystack, but the signatures of past or present life may be more wide spread through organics, methane sources, etc”.
NASA and ESA will issue an “Announcement of Opportunity for the orbiter in January 2010” soliciting proposals for a suite of science instruments according to McCuiston. “The science instruments will be competitively selected. They are open to participation by US scientists who can also serve as the Principal Investigators (PI’s)”. Proposals are due in 3 months and will be jointly evaluated by NASA and ESA. Instrument selections are targeted for announcement in July 2010 and the entire cost of the NASA funded instruments is cost capped at $100 million.
“The 2016 mission must still be formally approved by NASA after a Preliminary Design Review, which will occur either in late 2010 or early 2011. Funding until then is covered in the Mars Program’s Next Decade wedge, where all new-start missions reside until approved, or not, by the Agency”, McCuiston told me. ESA’s Council of Ministers just gave the “green light” and formally approved an initial budget of 850 million euros ($1.2 Billion) to start implementing their ExoMars program for the 2016 and 2018 missions on 17 December at ESA Headquarters in Paris, France. Another 150 million euros will be requested within two years to complete the funding requirement for both missions.
ESA has had to repeatedly delay its own ExoMars spacecraft program since it was announced several years ago due to growing complexity, insufficient budgets and technical challenges resulting in a de-scoping of the science objectives and a reduction in weight of the landed science payload. The ExoMars rover was originally scheduled to launch in 2009 and is now set for 2018 as part of the new architecture.
The Trace Gas orbiter combines elements of ESA’s earlier proposed ExoMars orbiter and NASA’s proposed Mars Science Orbiter. As currently envisioned the spacecraft will have a mass of about 1100 kg and carry a roughly 115 kg science payload, the minimum deemed necessary to accomplish its goals. The instruments must be highly sensitive in order to be capable of detecting the identity and extremely low concentration of atmospheric trace gases, characterizing the spatial and temporal variation of methane and other important species, locating the source origin of the trace gases and determining if they are caused by biologic or geologic processes. Current photochemical models cannot explain the presence of methane in the martain atmosphere nor its rapid appearance and destruction in space, time or quantity.
Among the instruments planned are a trace gas detector and mapper, a thermal infrared imager and both a wide angle camera and a high resolution stereo color camera (1 – 2 meter resolution). “All the data will be jointly shared and will comply with NASA’s policies on fully open access and posting into the Planetary Data System”, said McCuiston.
Another key objective of the orbiter will be to establish a data relay capability for all surface missions up to 2022, starting with 2016 lander and two rovers slotted for 2018. This timeframe could potentially coincide with Mars Sample Return missions, a long sought goal of many scientists.
If the budget allows, ESA plans to piggyback a small companion lander (EDM) which would test critical technologies for future missions. McCuiston informed me that, “The objective of this ESA Technology Demonstrator is validating the ability to land moderate payloads, so the landing site selection will not be science-driven. So expect something like Meridiani or Gusev—large, flat and safe. NASA will assist ESA engineering as requested, and within ITAR constraints.” EDM will use parachutes, radar and clusters of pulsing liquid propulsion thrusters to land.
“ESA plans a competitive call for instruments on their 3-4 kg payload”, McCuiston explained. “The Announcement of Opportunity will be open to US proposers as well so there may be some US PI’s. ESA wants a camera to ‘prove’ they got to the ground. Otherwise there is no significant role planned for NASA in the EDM”.
The lander would likely function as a weather station and be relatively short lived, perhaps 8 Sols or martian days, depending on the capacity of the batteries. ESA is not including a long term power source, such as from solar arrays, so the surface science will thus be limited in duration.
The orbiter and lander would separate upon arrival at Mars. The orbiter will use a series of aerobraking maneuvers to eventually settle into a 400 km high circular science orbit inclined at about 74 degrees.
The joint Mars architecture was formally agreed upon last summer at a bilateral meeting between Ed Weiler (NASA) and David Southwood (ESA) in Plymouth, UK. Weiler is NASA’s Associate Administrator for the Science Mission Directorate and Southwood is ESA’s Director of Science and Robotic Exploration. They signed an agreement creating the Mars Exploration Joint Initiative (MEJI) which essentially weds the Mars programs of NASA and ESA and delineates their respective program responsibilities and goals.
“The key to moving forward on Mars exploration is international collaboration with Europe”, Weiler said to me in an interview. “We don’t have enough money to do these missions separately. The easy things have been done and the new ones are more complex and expensive. Cost overruns on Mars Science Lab (MSL) have created budgetary problems for future mars missions”. To pay for the MSL overrun, funds have to be taken from future mars budget allocations from fiscal years 2010 to 2014.
“2016 is a logical starting point to work together. NASA can have a 2016 mission if we work with Europe but not if we work alone. We can do so much more by working together since we both have the same objectives scientifically and want to carry out the same types of mission”. Weiler and Southwood instructed their respective science teams to meet and lay out a realistic and scientifically justifiable approach. Weiler explained to me that his goal and hope was to reinstate an exciting Mars architecture with new spacecraft launching at every opportunity which occurs every 26 months and which advance the state of the art for science. “It’s very important to demonstrate a critical new technology on each succeeding mission”.

The next big thing for airliners made its maiden flight today. Boeing’s new 787 Dreamliner jet took off at 10:27 am (1827 GMT) from Paine Field near Boeing’s plant in Washington state in the US. As Boeing’s first new design model in over a decade, it takes advantage of advances in aviation technology and is capable of flying long-haul routes using up to 20 percent less fuel. At two year overdue, the milestone is critical for Boeing at the key to the future of the US aerospace company. Continue reading “Dreamliner Makes First Flight”
Heat shields are an important part of any space vehicle that re-enters the Earth’s atmosphere. The next generation of heat shields to protect astronauts and payloads on their re-entry into the Earth’s atmosphere may use superconducting magnets to deflect the plasma that forms in front of spacecraft as they travel at high speeds in the air. The first test of such a heat shield could happen as early as ten years from now, and the basic technology is already in development.
Traditional heat shields use the process of ablation to disperse heat away from the capsule. Basically, the material that covers the outside of the capsule gets worn away as it is heated up, taking the heat with it. The space shuttle uses tough insulated tiles. A magnetic heat shield would be lighter and much easier to re-use, eliminating the cost of re-covering the outside of a craft after each entry.
A magnetic heat shield would use a superconductive magnetic coil to create a very strong magnetic field near the leading edge of the vehicle. This magnetic field would deflect the superhot plasma that forms at the extreme temperatures cause by friction near the surface of an object entering the Earth’s atmosphere. This would reduce or completely eliminate the need for insulative or ablative materials to cover the craft.
Problems with the heat shield on a spacecraft can be disastrous, even fatal; the Columbia disaster was due largely to the failure of insulative tiles on the shuttle, due to damage incurred during launch. Such a system might be more reliable and less prone to damage than current heat shield technology.
At the European air and space conference 2009 in Manchester in October, Detlev Konigorski from the private aerospace firm Astrium EADS said that with the cooperation of German aerospace center DLR and the European Space Agency, Astrium was developing a potential magnetic heat shield for testing within the next few years.
The initial test vehicle would be launched from a submarine aboard a Russian Volna rocket on a suborbital trajectory, and land in the Russian Kamchatka region. A Russian Volan escape capsule will be outfitted with the device, and the re-entry trajectory will take it up to speeds near Mach 21.
Though the scientists are currently testing the capabilities of a superconducting coil to perform this feat, there is the challenge of calculating changes to the trajectory of a test vehicle, because the air will be deflected away much more than with current heat shield technology. The ionized gases surrounding a capsule using a magnetic heat shield would also put a wrench in the current technique of using radio signals for telemetry data. Of course, there are a long list of other technical challenges to overcome before the testing will happen, so don’t expect to see the Orion crew vehicle outfitted with one!
The European Southern Observatory (ESO) is planning on building a massive – and I do mean massive – telescope in the next decade. The European Extremely Large Telescope (E-ELT) is a 42-meter telescope in its final planning stages. Weighing in at 5,000 tonnes, and made up of 984 individual mirrors, it will be able to image the discs of extrasolar planets and resolve individual stars in galaxies beyond the Local Group! By 2018 ESO hope to be using this gargantuan scope to stare so deep into space that they can actually see the Universe expanding!
The E-ELT is currently scheduled for completion around 2018 and when built it will be four times larger than anything currently looking at the sky in optical wavelengths and 100 times more powerful than the Hubble Space Telescope – despite being a ground-based observatory.
With advanced adaptive optics systems, the E-ELT will use up to 6 laser guide stars to analyse the twinkling caused by the motion of the atmosphere. Computer systems move the 984 individual mirrored panels up to a thousand times a second to cancel out this blurring effect in real time. The result is an image almost as crisp as if the telescope were in space.
This combination of incredible technological power and gigantic size mean that that the E-ELT will be able to not only detect the presence of planets around other stars but also begin to make images of them. It could potentially make a direct image of a Super Earth (a rocky planet just a few times larger than Earth). It would be capable of observing planets around stars within 15-30 light years of the Earth – there are almost 400 stars within that distance!
The E-ELT will be able to resolve stars within distant galaxies and as such begin to understand the history of such galaxies. This method of using the chemical composition, age and mass of stars to unravel the history of the galaxy is sometimes called galactic archaeology and instruments like the E-ELT would lead the way in such research.
Incredibly, by measuring the redshift of distant galaxies over many years with a telescope as sensitive as the E-ELT it should be possible to detect the gradual change in their doppler shift. As such the E-ELT could allow humans to watch the Universe itself expand!
ESO has already spent millions on developing the E-ELT concept. If it is completed as planned then it will eventually cost about €1 billion. The technology required to make the E-ELT happen is being developed right now all over the world – in fact it is creating new technologies, jobs and industry as it goes along. The telescope’s enclosure alone presents a huge engineering conundrum – how do you build something the size of modern sports stadium at high altitude and without any existing roads? They will need to keep 5,000 tonnes of metal and glass slewing around smoothly and easily once it’s operating – as well as figuring out how to mass-produce more than 1200 1.4m hexagonal mirrors.
The E-ELT has the capacity to transform our view not only of the Universe but of telescopes and the technology to build them as well. It will be a huge leap forward in telescope engineering and for European astronomy it will be a massive 42m jewel in the crown.
Ever wonder what it would be like to walk on the Moon or run on Mars? A treadmill developed using NASA technology can provide users the feeling of moving about in less than 1 G. Anti Gravity treadmills, sold under the name of Alter-G, are becoming common in hospitals, rehab centers, and sports facilities, and just about every professional sports team in North America has one. They are a bit pricey for individuals to afford, but athletes and physical therapists say the device is a fantastic addition to their exercise repertoire.
Anti G treadmills allow people to improve mobility and health, recover from injury and surgery more effectively, overcome medical challenges that limit movement, and enhance physical performance. Runners and other athletes use the anti gravity treadmills to maintain their fitness level after a minor injury, without adding stress to their injury.
The Alter-G treadmill creates a seal around the user’s waist and then inflates to create a pressurized environment that can take away up to 80% of the user’s body weight, lessening the pounding to the joints.
The technology was first proposed for use on the space station to actually increase the amount of gravity felt by the body by using differential air pressure in space to mimic the Earth’s gravity to prevent bone loss and muscle deterioration.
Ames Research Center scientist, Robert Whalen, who came up with the idea said the anti-G trainer evolved directly from his original idea of how to add weight to an astronaut’s body during treadmill exercise in the low gravity of space. On Earth, it works just the opposite, giving users an astronaut-like experience.
A variety of patients—whether suffering from brain injury, neurological disorders, athletic injuries, or other stresses on the joints such as arthritis or morbid obesity—now use the NASA-derived technology in physical therapy.
In order for the G-Trainer to control air pressure effectively, users first have to don specially designed shorts which attach to a waist-level enclosure. After the person’s lower body is sealed in an enclosure – basically a big plastic bag around the treadmill, the system performs a calibration, adjusting to the person’s size and weight. Then running speed and incline can be chosen, along with what percent of weight should be removed. If a patient desires more unloading—more weightlessness—a button is simply pressed on a touch screen, and the air pressure increases, lifting the body, reducing strain, and further minimizing impact on the legs.
Prices run from USD $24,000 to $75,000 or leases for about $500 a month.
If you can build a better mousetrap, then you can certainly build a better glove for astronauts! Making a glove that both protects the hands of the astronauts in the harsh environment of space or on the Moon, and allowing them the dexterity to manipulate tools is a tough challenge for NASA. That’s why they are holding the second Astronaut Glove Challenge on November 19th, with a $400,000 prize for the best glove.
The layers of protection that an astronaut glove needs to have to shield against micrometeorites in space and insulate the hand of the wearer make for one rigid glove. The gloves are also pressurized, which makes them more rigid and further detracts from the mobility of an astronaut. NASA has held one previous competition to see who could build a better glove, in 2007, and the winner was Peter Homer, a former aerospace engineer. He took home the $200,000 prize last time, and is expected to return this year to compete against at least one other team. To read more about his story and see a video of his glove in operation, visit NASA’s page about him. Homer was also featured on Wired Magazine’s “Geek Dad” series, and a video interview is available here.
The last competition involved performing a series of tasks inside of a box that is under vacuum to measure how fatiguing to the fingers the glove was. The inside bladder of the glove was subjected to a burst test, in which it was pressurized to the point at which it bursts. The amount of force required to bend each finger of the glove was also measured.
These same rules will apply in this year’s competition, but the added challenge will be to perform all of these tests inside of an improved thermal micrometeorite garment, the outside layer of the glove that protects the astronaut’s hand from damage. This is basically a complete glove that is ready for operation in space.
NASA has been holding several challenges with some hefty prizes to incite development in space-related technology. The Centennial Challenge program most recently gave away prizes for the Power Beaming Challenge and the Lunar Lander Challenge. The prize will be provided by NASA, but the competition is managed by Volanz Aerospace Inc. of Owings, Md. and sponsored by Secor Strategies, LLC of Titusville, Fla.
Good luck to all the competitors, and may the best glove win!
The 2009 Space Elevator Games ran from November 4-6, and there is a winner! LaserMotive from Seattle took home the Level 1 prize of $900,000. Three teams competed for the $1.1 million and $900,000 prizes in this year’s event: LaserMotive from Seattle, the Kansas City Space Pirates, and the University of Saskatchewan Space Design Team (USST).
As we covered last week, on the very first day of the event LaserMotive successfully climbed the 1km (.6mile) ribbon “racetrack” at NASA’s Dryden Flight Research Center at Edwards Air Force Base near Mojave, California. LaserMotive is the first team that has qualified for a prize in the 5 years the games have run. They made a successful climb of the 1km ribbon at 4m/s (13ft/s), far beyond the 2m/s requirement for the Level 1 prize. LaserMotive made 4 runs of above 2m/s (6.6ft/s), an impressive showing considering that this is the first time a team has made the 1km mark, let alone qualify for one of the prizes! Their top time of 3-minutes 47-seconds was on Thursday.
The Kansas City Space Pirates made several climbs, none of which reached the top of the cable. Though their lasing system is the most powerful, they had trouble tracking the climber throughout the competition and were unable to get it up past about the halfway point.
USST didn’t have much luck this time around. Their climber had a number of issues, and during many of their climbing windows it was completely grounded.
The Level 2 prize of $1.1 million still remains unclaimed. This will go to the team that can climb 1km at 5m/s (16.5 ft/s) or more at the next Power Beaming Challenge. LaserMotive made an unsuccessful attempt to lighten their climber and get it to the 5m/s mark on the last day of the games. Maybe next year?
The Space Elevator Games/Power Beaming Challenge are part of NASA’s Centennial Challenges program, which provides monetary incentives for private companies to develop technologies in space-related fields. Just last week, the program handed out $1.5 million for the The Northrop Grumman Lunar Lander X-Prize challenge. The Space Elevator Games are run by the Spaceward Foundation.
Check back with us here at Universe Today next year to see if anyone nabs the big prize!
BREAKING NEWS: LaserMotive successfully qualified for the $900,000 prize! Their official speed was 3.72 m/s. Way to go! See more below.
Though it’s unlikely that anyone will be pressing the elevator button labeled ‘Space’ on one of the competitors’ vehicles this year at the 2009 Space Elevator Games, there is hope that a winner will walk away with the $1.1 million prize. Three different teams will compete to see if any can send a laser powered vehicle up a thin but strong ribbon 1km (.6 miles) into the sky. Italian readers can bet on this game using any of the online casinos that offer these odds – many of which can be found on our recommended casino resource Stranieri.com. Stranieri offers the best online casino reviews for betting on things like markets and slots, as well as space events like this one as well as other Air Force events.
This is the 5th year of the games, which started in 2005. The games are part of NASA’s Centennial Challenges program, which awards monetary prizes in the attempt to spur new technologies. This is a busy week for the program; as we covered earlier today, the Northrop Grumman Lunar X-prize announced two winners, and is part of the Centennial Challenge program.
To win the $1.1 million prize, one of the teams must propel their vehicle 1 km (.6 miles) into the sky at an average of at least 5 m/s (16.4ft/s). A second place prize of $900,000 will be awarded to any team that can go the 1km at an average of 2m/s (6.6 ft/s). The games this year will run from November 4th-6th, with each team getting the chance to launch their laser powered vehicles during a pre-determined 45-minute window for each day of the competition. The event takes place at NASA’s Dryden Flight Research Center at Edwards Air Force Base near Mojave, California.
For each test, a helicopter brings the elevator up the cable to a fixed starting point. The team is then given a go to calibrate their laser, and start beaming power to the craft. Each elevator uses small wheels to grip the ribbon, which is held aloft by a balloon tethered by three guy wires.
For a taste of what these elevators look like, check out this video:
Here’s a breakdown of what happened so far today: The Kansas City Space Pirates gave it three tries. In the first attempt, their elevator failed to take off. After fixing the problem, they were able to get the craft to move, but it then stopped. During the third, it started to climb the ribbon but they were unable to keep the laser locked on the elevator to power it, and it wasn’t able to climb the 1km to the top of the ribbon and brought back down.
LaserMotive had much better luck, despite a no-go on their initial attempt. Their elevator was lifted to the start by the helicopter, but failed to move despite repeated lasing attempts. After bringing it down for a tweak or two, the elevator was again placed at the start. It took off, making the first 300m (985ft) in a little under a minute, which met the 5m/s goal. The speed tapered off towards the top, but they bumped up against the 1km mark at approximately 4 minutes, making them the first to successfully claim the minimum 2km/s prize! While watching the live feed of this fantastic feat, I overheard a transmission from LaserMotive saying, “This is LaserMotive requesting permission to breathe.”
USST will not launch today, as there are no more open windows where satellites overhead will not be accidentally hit by the intense lasers used as power sources for the elevators. They will go tomorrow, November 5th, at 7am PST. Be sure to check back with us at Universe Today for more coverage, or head over to the official site for live streaming.
