    An interesting aspect of global warming..Was thinking of that today and apparently there are some studies but very limited.Involves a lot of satellite data to measure also moisture etc. in the atmoshpere

  • Finding power laws has now become de rigueur when analyzing popularity distributions. Long tails have been reported for the frequency of word usage in many languages [2], the number of citations of scientific papers [3], the number of visits (hits) to individual websites in a given time interval [4], and many more.

    Is there such a law for the technology used in satellites ?

    the largest cable into the Netherlands comes in apparently at Katwijk - we should have super fast internet!!! :-)
  • Ma Ru on 15 Jul 11
     
    You mean: "then why don't we have super fast internet?" :-) If you zoom the map in, it's actually way past Noordwijk. My quess is this could be attached somewhere near the naval radio station area? This remembered me the good old times of bike trips in the dunes, eh...

    well, the description says clearly Katwijk; am quite sure that the maps are less accurate than the description ...

  • Lizards were sent into orbit as part of study into effects of weightlessness on sexual intercourse
  • On Thursday, the team behind the research confirmed that the vessel was not responding to commands, potentially leaving the reptiles to their out-of-this-world sexual intercourse while video footage continues to beam down to Earth.

Experimental space telescopes to be 3D-printed at NASA - Laser Focus World - 0 views

    From the article: By the end of September 2014, Jason Budinoff, an aerospace engineer at NASA's Goddard Space Flight Center (Greenbelt, MD), is expected to complete the first imaging telescopes ever assembled almost exclusively from 3D-manufactured components. The devices' optics and electronics will be fabricated using conventional methods. "As far as I know, we are the first to attempt to build an entire instrument with 3D printing," says Budinoff. He is building a fully functional 50 mm camera whose outer tube, baffles, and optical mounts are all printed as a single structure. The instrument is appropriately sized for a CubeSat (a small satellite made of individual units each about 100 mm on a side).
