    A habitable settlement will be waiting for the settlers when they land. The settlement will support them while they live and work on Mars the rest of their lives

    Nice video featuring the technology. Plus it comes with a good soundtrack! Google's project wing uses a lifting wing concept (more fuel efficient than normal airplane layouts and MUCH more efficient than quadrocopters) but it equips the plane with engines strong enough to hover in a nose up position, allowing vertical landing and takeoff. For the delivery of packages the drone does not even need to land - it can lower them on a wire - much like the skycrane concept used to deliver the Curiosity rover on Mars. Not sure if the skycrane is really necessary but it is certainly cool. Anyways, the video is great for its soundtrack alone! ;-P

    could we just use genetic algorithms to evolve these shapes and layouts? :P

    Honest question, are we ever going to see this in practice? I mean besides some niche application somewhere, isn't it fundamentally flawed or do I need to keep my window opened on the 3rd floor without a balcony when I ordered something from DX? Its pretty cool yes, but practical?
  • Guido de Croon on 02 Sep 14
     
    Package delivery is indeed more complicated than it may seem at first sight, although solutions are possible for instance by restricting delivery to distribution centers. What we really need of course is some really efficient and robust AI to navigate without any problems in urban areas : ) The hybrid is interesting since it combines the advantage of a Vertical Takeoff and Landing (and hover), and a wing for more efficient forward flight. Challenges lie in the control of the vehicle under any angle and all that this entails also for higher levels of control. Our lab has first used this concept a few years ago for the DARPA UAVforge challenge, and we had two hybrids in our entry last year for the IMAV 2013 (for some shaky images: https://www.youtube.com/watch?v=Z7XgRK7pMoU ).
  • Thijs Versloot on 04 Sep 14
     
    Fair enough, but even if you consider advanced/robust/efficient AI, why would you use a drone? Do we envision hundreds of drones above our heads in the street instead of UPS vans, or postmen, considering delivers letters might be more easily achievable. I am not so sure if personal delivery will take this route. On the other hand, if the system would work smoothly, I can image that I'm send a mail with the question whether I'm home (or they might know already from my personal GPS tracker) and then notify me that they are launching my DVD and it will come crashing into my door in 5min.
  • Paul N on 08 Sep 14
     
    I'm more curios how they're planning to keep people from stealing the drones. I could do with a drone army myself and having cheap amazon or google drones flying about sounds like a decent source.

NASA Next Mars Rover Mission: new landing technology - 3 views

JPL is also developing a crucial new landing technology called terrain-relative navigation. As the descent stage approaches the Martian surface, it will use computer vision to compare the landscape...

    The Opportunity rover, which landed on Mars nearly eight years ago, has discovered a thin, bright mineral vein along the rim of a huge crater called Endeavour. This mineral is almost certainly gypsum that was deposited by liquid water billions of years ago, researchers said.

    Check the landing video from the onboard camera - Guido: how well would our optical flow algorithm cope with such images? Looks quite complicated to me....

    Note that videos there are said to be "thumbnail" quality, so I think videos with higher resolution (and possibly frame rate) have been acquired, just that they were not downloaded yet.

AI UAV StarTiger

shared by Luís F. Simões on 08 Jul 14 - No Cached
  • “StarTiger is a fresh approach to space engineering,” explains Peter de Maagt, overseeing the project. “Take a highly qualified, well-motivated team, gather them at a single well-equipped site, then give them a fixed time to solve a challenging technical problem.”
  • StarTiger stands for ‘Space Technology Advancements by Resourceful, Targeted and Innovative Groups of Experts and Researchers’ working within the Agency’s TRP Basic Technology Research Programme. It brings team members together on a single site to work on a set challenge, aiming to produce a working prototype by the end of the project’s time limit.
  • Luís F. Simões on 08 Jul 14
     
    StarTiger: similar, yet different from the way the ACT does things. Seems like a very interesting programme.
  • Thijs Versloot on 10 Jul 14
     
    Nice initiative and also a good approach, problem-oriented within a fixed time frame. Could definitely be a highly motivating approach, similar to GTOC... I think the ACT should do this more often, targeted at future technologies and/or missions. The team could be structured around 'problems' instead of 'research areas', this will promote multidisciplinary work as well, plus it will also focus activities more. The problems, or more broadly concepts, are identified by the team and a few get chosen as main activities. Subsequent RF and YGT hiring is then done to strenghten the research team. These projects have a maximum lifetime maybe of 1 year? Thoughts?
  • Ma Ru on 10 Jul 14
     
    I'm impressed already by what an innovative group of experts and researchers was able to achieve when resourcefully targeted at coming up with the project's name...

    In similar story (http://www.orlandosentinel.com/news/os-spacex-rocket-elon-musk-20110405,0,3234336.story) the quote: " "This is a rocket of truly huge scale," said Musk, adding it would have the capability to one day enable moon or Mars missions." tells a lot about the ambition of it...

    even bigger booster also coming: China Aims To Build World's Largest Rocket "Back in March, China revealed it is studying the feasibility of designing the most powerful carrier rocket in history for making a manned moon landing and exploring deep space, according to Liang Xiaohong, vice head of the China Academy of Launch Vehicle Technology. The rocket is envisaged to have a payload of 130 tonnes, five times larger than that of China's current largest rocket. This rocket, if built, will eclipse the 53 tonne capacity of the planned Falcon 9 Heavy from SpaceX. It will even surpass the largest rocket ever built, the 119-tonne Saturn V."
