NASA Unveils Centennial Challenges 262

Posted by samzenpus from the step-right-up dept.
wonderfesten writes "NASA has finally got its Centennial Challenges program off the ground. Like the X Prize, the Challenges award cash prizes to private inventors who come up with solutions to problems. The first challenges are to design a light-weight, ultra-strength tether and a means of transmitting power wirelessly. But with a prize of just $50,000, will anyone give it a shot?" Details also available on MSNBC and Space.com.

        Thank you for posting the real link for this story.

        To everyone who is positing various ways of transmitting power wirelessly, they already have a method in mind:

        Showcasing the first representative prototypes of Space Elevator climbers, this event will re-define public perception of the Space Elevator project by taking the first step away from mathematical models and drawing boards and into the world of real working hardware. By participating, you get the opportunity to partner in writing this unique chapter of history.

        The competition provides the race track, in the form of a crane-suspended vertical ribbon, and a strong light source to power the climbers. Competing teams provide climbers, which have to use the power beamed to them and scale the ribbon while carrying some amount of payload. Climbers will be rated according to their speed and the amount of payload they carried.

        The climbers (unmanned, of course) will weigh 25-50 kg [50-100 lbs], and will ascend the ribbon at about 1 m/s. [3 feet per second or 2.5 MPH]

        The beam source is a 10 kWatt Xenon search-light (80 cm beam diameter, about 25% efficient), which should yield a climber power budget of about 500 watts.

        The ribbon is roughly 30cm (1 foot) wide by 1 mm thick, is about 60m (200 feet) long, and is tensioned to about 1 ton.

        Building a climber is not an easy task. The designers have to juggle light weight structure, efficient photo-voltaic arrays, efficient motors and power electronics, low-loss traction mechanism, thermal management, and control systems.

        Not a walk in the park, but we'll make it worth your while. We will be offering $50,000, $20,000 and $10,000 to the 3 best teams.

      I have wondered why the space elevator people want to use transmitted power. Why not just have your tether be a loop with a pully on the satellite? Then you just clamp a payload on and turn a crank on the ground. You get bi-directional delivery at the same time. Now there are potential issues with the 2 strands and associated payloads running into each other, but that seems like it should be easier to solve than all the issues with robotic climbers with beamed power.

    NASA Announces First Centennial Challenges' Prizes

    NASA and its partner, the Spaceward Foundation, today announced prizes totaling $400,000 for four prize competitions, the first under the agency's Centennial Challenges program.

    NASA's Centennial Challenges promotes technical innovation through a novel program of prize competitions. It is designed to tap the nation's ingenuity to make revolutionary advances to support the Vision for Space Exploration and NASA goals. The first two competitions will focus on the development of lightweight yet strong tether materials (Tether Challenge) and wireless power transmission technologies (Beam Power Challenge).

    "For more than 200 years, prizes have played a key role in spurring new achievements in science, technology, engineering and exploration," said NASA's Associate Administrator for Exploration Systems Mission Directorate, Craig Steidle. "Centennial Challenges will use prizes to help make the Vision for Space Exploration a reality," he added.

    "This is an exciting start for the Centennial Challenges program," said Brant Sponberg, program manager for Centennial Challenges. "The innovations from these competitions will help support advances in aerospace materials and structures, new approaches to robotic and human planetary surface operations, and even futuristic concepts like space elevators and solar power satellites," he said.

    The Tether Challenge centers on the creation of a material that combines light weight and incredible strength. Under this challenge, teams will develop high strength materials that will be stretched in a head-to-head competition to see which tether is strongest.

    The Beam Power challenge focuses on the development of wireless power technologies for a wide range of exploration purposes, such as human lunar exploration and long-duration Mars reconnaissance. In this challenge, teams will develop wireless power transmission systems, including transmitters and receivers, to power robotic climbers to lift the greatest weight possible to the top of a 50-meter cable in under three minutes.

    The winners of each initial 2005 challenge will receive $50,000. A second set of Tether and Beam Power challenges in 2006 are more technically challenging. Each challenge will award purses of $100,000, $40,000, and $10,000 for first, second, and third place.

    "We are thrilled with our partnership with NASA and we're excited to take the Tether and Beam Power challenges to the next level," said Meekk Shelef, president of the Spaceward Foundation.

    The Centennial Challenges program is managed by NASA's Exploration Systems Mission Directorate. The Spaceward Foundation is a public-funds non-profit organization dedicated to furthering the cause of space access in educational curriculums and the public.

    Today, good ir lasers can get 60% wallplug efficiency (>99% quantum efficency and little outcoupling losses, plus little additional resistances adding to the bandgap).
    The main reason why solar cells are unefficient is that you have to gamble with the bandgap: set it too high, and you will lose to many low energy photons. set it too low, and all those high energy photons will lose all energy >E_gap as phonons/heat. So even an absolutely ideal Solar cell could only get a little over 25% or so efficiency with a backbody spectrum.

    But now take a laser and create a optimally tuned solar cell with a bandgap just a bit lower than the laser wavelenght. You should be able to get 20-30% total transmission efficiency at least, imho, after a little optimisation.
    That doesnt sound too good, but its not so bad compared to other ways to store and carry energy (batteries, ect).

      NASA has always been aware of the risks of space flight. So have the astronauts who went into orbit, as well as to the moon. Man has always taken risk (had balls, as you so delicately put it) to push the frontier a little further away.

      Just because the media has duped sheep such as yourself into believing that space is too dangerous and NASA needs massive reforms doesn't mean that the majority of people feel that way. That's one reason that there isn't a si

  • Wake me up when they come up with a light weight ultra strength means of transmitting power *and* a wireless tether.
  • If NASA offered a major prize, say one, five or ten million dollars, it'd be both a sizeable chunk of their budget and something which might just produce far more results for the money than NASA itself does.

    It is therefore not a huge surprise to find the prize is paltry.

    I know there are plenty of people at NASA who'd encourage this sort of prize based competition and would want a large prize, because they really want space travel to get going, but the behaviour of an *organisation* as a whole is *not* th

    It seems to me that questing for wireless power transmission is a waste of time. The problem with high-power microwave beams is that anything getting in the way would get cooked, same with lasers. The focus should instead be on miniaturization of power sources such as fuel cells, and maybe even miniature elementary particle power generators that harness the energy that permeates the universe on a quantum level.
  • How about the NASA challenge of just getting off the ground?

  • Honestly, I'm a little confised. I know people always assume beamed power when talking about the space elevator. But I also usually hear about the tether being made of carbon nanotubes [google.com]. And I know I heard about research in superconducting carbon nanotubes [google.com].

    Anyone wanna tell me why this isn't a promising direction of research?

    Wireless power in many instances is easy but low powered. What the focus needs to be on is superconducting materials that enable us to make devices that require minimal power to function.

    Imagine a watch that took your body heat and with the right chips in the watch would convert that heat and power/charge the watch.

    The same could be said for any number of ways to get power somewhere. If things were ultra low powered then fiber optics could be used to power devices.

    That is also a reason I think seti faces a problem. Modern civilizations may be using superconductor tech that gives them virtually no ELM footprint past their local region of space. If we do find something more likely that signal will fade and eventually dissapear over time.
  • Why, just yesterday, I submitted my patents on devices for climbing light-weight, ultra-strength tethers, operating on broadcast power, such as laser beams.

    I already had a patent pending on "tethers or tethering-style devices or mechanisms which are light in weight, and yet simultaneously and concurrently ultra in strength".

    I submitted this story a couple of times yesterday, but it sadly wasn't accepted. Maybe it was too long or had too many links? In any case, here's a copy, which has a little additional info:

    MSNBC [msn.com], Space.com [space.com], and Wired [wired.com] report that NASA, in collaboration with the non-profit Spaceward Foundation, has announced [nasa.gov] its first two Centennial Challenges. The Centennial Challenges, inspired by the Ansari X Prize and DARPA Grand Challenge, are prize contests [elevator2010.org] seeking to stimulate private industry development [msn.com] of technologies relevant to space exploration. One contest is the Tether Challenge, for building the sort of super-strong tether needed to make a space elevator feasible. The other is the Beam Power Challenge, for creating a wirelessly-powered ribbon-climbing robot capable of lifting as large a payload as possible within a limited timeframe. The initial set of challenges in 2005 will award $50K to the winners of each contest. A second set of challenges in 2006 will award first, second, and third place prizes worth $100K, $40K, and $10K. It's hoped that these contests will further space elevator technology and help eliminate the 'giggle factor' surrounding them. Additional contests will be announced in the coming weeks, although Congress currently restricts NASA from awarding prizes of more than $250K; the agency is lobbying to try to get this limit raised to $40 million for future prizes.
