Google's $30,000,000 Lunar X PRIZE

chroma writes "It's been a long time since anyone has explored the surface of the moon. But now Google has teamed up with the X PRIZE Foundation to offer a $30,000,000 bounty to the first privately funded organization to land a robotic rover on the moon. Google, of course, has offered the free Google Moon mapping service for a few years now. Looks like the other search engines have some catching up to do in the space exploration department."

  6. Lunokhod program; other thoughts by FleaPlus · · Score: 5, Interesting
    If I recall correctly, the only unmanned rovers that have explored the Moon are the pair of rovers of the Lunokhod programme of Russia (then Soviet Union), during the early 1970s. From wikipedia:

    Lunokhod 2 was equipped with three television cameras, one mounted high on the rover for navigation, which could return high resolution images at different rates--3.2, 5.7, 10.9 or 21.1 seconds per frame (not frames per second). These images were used by a five-man team of controllers on Earth who sent driving commands to the rover in real time. There were 4 panoramic cameras mounted on the rover.

    Power was supplied by a solar panel on the inside of a round hinged lid which covered the instrument bay, which would charge the batteries when opened. A polonium-210 radioactive heat source was used to keep the rover warm during the long lunar nights. ...

    During its 322 Earth days of operations, Lunokhod 1 traveled 10.5 km and returned more than 20,000 TV images and 206 high-resolution panoramas. In addition, it performed twenty-five soil analyses with its RIFMA x-ray fluorescence spectrometer and used its penetrometer at 500 different locations.

    Lunokhod 2 operated for about 4 months, covered 37 km (23 miles) of terrain, including hilly upland areas and rilles, and sent back 86 panoramic images and over 80,000 TV pictures. Many mechanical tests of the surface, laser ranging measurements, and other experiments were completed during this time. With regards to a human lunar base, I think the prize could also have great benefits. I think it's pretty much a given that robots and rovers will play an integral support role of a manned lunar base, and getting robots to operate in a lunar environment is still something we have little experience with. The prize will likely lead to discovering plenty of new ideas and techniques which do and don't work on the lunar surface.

    Also, rovers are a great way to captivate people's attention. Just look at how much the Mars rovers has increased people's attention at what's going on with Mars. For my generation, lunar exploration (human or robot) is something that exists only in history books. Seeing the Moon through the eyes of a rover (a rover put up by entrepreneurs, not a government) can change that, and increase support for human exploration of the Moon.

    Also, I think this is a great way for the "space == science only" crowd to get interested in private space activity. Thus far, many of them have either been ambivalent about private space, or outright antagonistic about it ("just a way for rich people to waste money"). This prize helps cement the idea that yes, private spaceflight can have benefits for science.

    15. How much do you think it will cost for a rover to get to the Moon and sustain itself throughout the competition?

    Traditionally, prizes have encouraged people to invest a wide range of resources. Lindbergh was one of few to spend less than the prize amount during the Orteig prize--others, like Admiral Byrd, spent nearly $100,000, or four times the $25,000 prize value. It has been reported that Mojave Aerospace Ventures spent significantly more than the $10 million purse to win the Ansari X PRIZE. Teams are willing to spend more than the prize value, as they get to keep their intellectual property and capitalize on it. In the case of the Google Lunar X PRIZE, we expect some teams to be willing to spend more than the value of the prize. Other teams may be able to complete the mission at or below the value of the Grand Prize purse. I don't think comparing the prize reward from a 1919 prize award of flying from Paris to NYC is accurate. I mean, people had already been flying. How many people put things into orbit, much less on the moon?

    Just to put this into perspective, the pair of Mars rovers cost NASA $820 million. Granted you're only expected to send one and it's only to the moon, NASA does already have the infrastructure & experienced personel to do this. Even an 1/8 of that cost is 3 times the prize money.

    Add the requirements of a 500 meter 'rove' and hi def 'Mooncast' and I think you're looking at too much risk for any person--possibly any company.

    Frankly, I don't think $30 million is enough. I know it may sound ridiculous but I personally think $300 million would start to entice competition. What intellectual property would you have in the end? You would have patents on specifically design tools for getting a piece of machinery to the moon only capable of Mooncasts & 500 meters of roving. I'm not so sure any company would try to enter this competition as it is a major investment and a major risk with very little gain.

This is similar to Branson's prize he's offering for removing CO2 from the atmosphere at some rather significant rate; the challenge to be surpassed in meeting the qualifications are high enough that there is little chance of having to make a payout.

    If they do have to make a payout, the publicity is huge, and it's certainly possible that they have some commercial return in mind...perhaps rights to the rover design. I think the field of contenders will be small and weak, because the challenge is significant and the prize amount is unlikely to match the cost. At least for the original X-prize there was a hypothesized market for system developed as a result.

    Of course, if I'm going to say this on Slashdot, I'd better be prepared to back it up:

    The guidelines are that it must soft-land on the moon by the end of 2012, roam 500+ meters, and send back video and pictures. The basic prize is $20 million. If it can be done by 2014, the prize is $15 million. There is an additional $5 million if a second lander (by any competitor) to land by 2014. There is a bonus $5 million for extra duties like roaming 5000+ meters, photographing existing man-made objects on the moon, surviving the 14 day lunar night, or discovering water-ice.

    The requirements and bonus objectives are roughly inline with the design parameters of the Mars Exploration Rovers. I'm sure a private group can build a device with that kind of capabilities for less than $30 million. However, I'm positive they can't get it to the moon for that little.

    Landing a meaningful payload on the moon requires a fairly decent-sized launch vehicle. If we assume a mass similar to the old Surveyor Lunar landers, which were about 1/3 as heavy as the MER's (landing mass, not mobile mass) and not mobile, then we can start looking at launch vehicles capable of sending it on it's way.

    The Surveyors were launched on Atlas-Centaur rockets, which have an LEO payload of about 5000 pounds. There isn't anything directly comparable currently on the market. There's few offerings that are too small. A Falcon 1 ($8 million, 1500 pounds) won't cut it. A Falcon 9, on the other hand would be significant overkill, with 21,000 pound LEO capacity and a $35 million price tag.

    A Russian Dnepr would probably be the best bet. These converted ICBM's are what Bigelow hired to launch his two prototype inflatable modules with. It has an 8000 pound LEO capacity and costs $15-20 million.

    So you're left with $5-10 million (because the last $5 million are only available to a second mission) to develop and build the rover (piece of cake), but also a reliable landing platform and an earth departure stage. The latter can probably be adapted from existing upper stage products, but the first two are being done from scratch.

    I just can't imagine that much work being accomplished, even with heavy use of volunteer labor, for that price.

And since we have to launch at exactly 11:23pm, some neighbours may complain about a bit of noise. This should be limited to about the sound of being in the center between 4 jet-engines running at full power, but should last only about 4.3 seconds. The ear ringing might last a week or two.

    Ofcourse our research isn't complete yet. We are still working on the radiation protection of the robot, finding the cheapest sunblock creme isn't that easy. But we expect to be ready to launch around newyear 2009.

    Launch vehicle: The Minotaur V (not yet in production as far as I know), essentially refurbished and upgraded ICBM, should be able to deliver a 100kg or so payload into lunar orbit. DoD has thousands of Minotaurs that are scheduled for retirement. It is possible for a government agency (don't know about private enterprise) to request repurpose of one of these Minotaurs. Cost? One off - maybe $20M each. Buy in bulk - I've heard $7M each. This is not including launch services which also run into multiple $M.

    Probably the most economical way for a competitor to get to the moon will be to go as a secondary payload with another mission - sharing the same launcher. In most cases, this would be to Earth orbit (low) and a translunar injection stage will be needed to get to lunar orbit insertion (LOI). Still going to cost multiple $M.

    Better yet --- catch a ride with somebody else who is going to the moon. Who? China, India, Europe -- all have announced lunar orbiting missions to be launched in the next several years. It is too late to team up with India on their first mission. China maybe? NASA is deciding whether to send a science mission to lunar orbit (two are already in the works for launch in Oct 2008: LRO http://lro.gsfc.nasa.gov/ and LCROSS http://lcross.arc.nasa.gov/ ). LCROSS is a secondary payload for LRO and has a budget of under $100M. It won't exactly land... let's call it a "sporty" landing.

    The next NASA mission could use a Delta IV; if so, there will be plenty of room within the fairing on the next mission for a secondary payload (if the mission is approved). That could be a "free" delivery to lunar orbit.

    Putting a spacecraft on the surface with not less than 5kg useful payload is possible, but a rover (especially one with the capabilities required by the prize) will likely be quite a bit heavier, and more costly.

    I know of one team that thinks they can do such a mission - including the launcher - for under $100M. Maybe $75M on a good day. Most in NASA would say $120M would be cutting it very tight ... need more like $175M.

    Where will the money come from? How about sponsorship from a few companies who would like to be associated with a lunar mission? Pick any 10 at $10M each and you are on your way.
