Wireless 10 kW power transmission - 1 views

  •  
    Mitsubishi Heavy Industries said Friday that it has succeeded in transmitting 10 kW of power through 500 m. An announcement that comes just after JAXA scientists reported one more breakthrough in the quest for Space Solar Power Systems (http://phys.org/news/2015-03-japan-space-scientists-wireless-energy.html). One step closer to Power Generation from Space/
  •  
    from the press release (https://www.mhi-global.com/news/story/1503121879.html) "10 kilowatts (kW) of power was sent from a transmitting unit by microwave. The reception of power was confirmed at a receiver unit located at a distance of 500 meters (m) away by the illumination of LED lights, using part of power transmitted". So 10kW of transmission to light a few efficient LED lights??? In a 2011 report (https://www.mhi-global.com/company/technology/review/pdf/e484/e484017.pdf), MHI estimated this would generate the same electricity output as a 400-megawatt thermal plant - or enough to serve more than 150,000 homes during peak hours. The price? The same as publicly supplied power, according to its calculations. There are no results to boost these claims however. The main work they do now is focused on beam steering control. I guess the real application in mind is more targeted to terrestrial applications, eg wireless highway charging (http://www.bbc.com/future/story/20120312-wireless-highway-to-charge-cars). With the distances so much shorter, leading to much smaller antenna's and rectenna's this makes much more sense to me to develop.

Antimatter Starship Scheme Coming to Kickstarter - 1 views

  •  
    "Hbar Technologies plans a Kickstarter effort to raise US $200,000 for the next phase design of an antimatter-propelled spaceship. The two scientists behind this design effort are a veteran Fermilab particle accelerator scientist and a former Los Alamos National Laboratory physicist and founding director of the U.S. Center for Space Nuclear Research. They originally developed it for NASA at the turn of the millennium."

Suburban space oddities | 1843 - 0 views

  •  
    "The forecasts were the product of a series of "summer studies" led by NASA's Ames Research Centre and Stanford University, at which top academics, scientists, and engineers gathered to imagine how future space colonies could look. Artists gave life to the blueprints, producing a stunning series of images that look like a cross between CGI real-estate models (complete with would-be residents smugly sipping wine) and the fantastical worlds of Isaac Asimov."

    For the first time, ultra-cold atoms interfere in space The MAIUS 1 experiment was launched on 23 January 2017 at 3:30 CET on board a sounding rocket from Esrange Space Center near Kiruna in northern Sweden. German scientists have, for the first time, succeeded in producing a Bose-Einstein condensate in space and using it for interferometry experiments.

Hubble to Watch Historic Venus Transit, Using Moon as Mirror - 2 views

  •  
    "Scientists are planning to use NASA's Hubble Space Telescope to observe next month's historic transit of Venus across the sun's face. But there's a twist. Researchers can't point Hubble anywhere near the sun, because our star's bright light could damage the telescope's super-sensitive instruments. So Hubble will watch the June 5-6 Venus transit by using the moon as a mirror."

Prolonged Space Travel Causes Brain and Eye Abnormalities in Astronauts | SpaceRef - Yo... - 1 views

  •  
    "Magnetic resonance imaging (MRI) of the eyes and brains of 27 astronauts who have spent prolonged periods of time in space revealed optical abnormalities similar to those that can occur in intracranial hypertension of unknown cause, a potentially serious condition in which pressure builds within the skull."

First Digital Message Sent Using Neutrinos - Technology Review - 1 views

  •  
    ...obvious use for space...
  •  
    Indeed, you only need ONE antenna to communicate with your satellite irrespective of its position, since one can freely send the signals right through the Earth. Small disadvantage: you should tell the launcher section to design a new launcher that is capable to bring a 200tons detector to space...

Kepler space telescope could find exomoons - physicsworld.com - 0 views

  •  
    NASA's Kepler space telescope could be used to find exomoons, which are the moons of planets orbiting stars other than the Sun. That is the claim of an international team of astronomers, which says that careful analysis of data collected by Kepler could reveal if such exoplanets are circled by moons.

NASA studying solar-electric propulsion for "space tugboat" - 0 views

  •  
    NASA announced it was seeking proposals for mission concept studies of a high-power solar electric propulsion (SEP) system that could be used in a "space tugboat." Such a ship would be used ferry payloads in low Earth orbit (LEO) into higher energy orbits,

    New technology (STARE-a constellation of nano-satellites) for tracking satellites and space debris could improve the accuracy from 1km (current by NORAD) to less than 100m. Increasing the reliability of collision detection, preventing 99% of false warnings.

    why are we not getting these type of startups in Europe .... btw: Will is british
  • ...1 more comment...
  •  
    Nobody in Europe would invest 13Mio $ (or the equivalent in €) venture capital for this idea, it's just a different mentality. In Europe, VCs start to get interested when the investment risk is significantly lower.
  •  
    I agree, the mentality is different, it's hard to find VC funding for hardware stuff, even more so if you wanna shoot your HW into space. but there is movement, e.g. pioneers.io, they are in vienna and are actively trying to get more VC funding (in europe) for HW and other engineering startups
  •  
    thanks for the link ... just read this blog ... http://pioneers.io/blog/space-race-2-0-putting-satellites-into-the-hands-of-everyone a lot of selling talk but fundamentally I agree that they have a point ... and as ACT we will face the criticism in not so long that we have not managed (nor tried hard enough) to convince ESA about the need to embrace this "new space"

Noordwijk | Space Apps Challenge - 1 views

  • On the weekend of the 12 and 13 April 2014 ESA Business Incubation Centre Noordwijk and Verhaert Connect are proud to host the NASA International Space Apps Challenge in the European Space Innovation Centre Noordwijk.
  • Developers, designers, innovators all kinds of creative thinkers from all seven continents will come together for two days of creativity and computer coding to address challenges of global importance. This year we expect to have about 40 challenges that support NASA's mission directorates in five themes: Earth Watch, Technology in Space, Human Spaceflight, Robotics and Asteroids.
  •  
    "Developers, designers, innovators all kinds of creative thinkers" aka "nerd objective-C programmers with no life"?
  •  
    Well, the ACT actually proposed a few of the topics (BEWARE, THERE BE CUCUMBERS!). Some are not necessarily software based, like creating a LEGO model of the ExoMars rover (although they stripped LEGO from the challenge description and now it just says "create an ExoMars rover from hardware" ... ). Also we had no clue that they would host part of the challenge here at ESTEC - so our 5 or 6 challenges will all be hosted in Rome... ...
