Space shuttles for sale - Short Sharp Science - New Scientist - 4 views

  • If an entire shuttle is beyond your budget, consider a main engine instead. NASA had hoped to charge up to $800,000 for these but lack of interest has forced it to slash the price. They are now available for free

    will it fit in diego's van?

NASA will miss Congressional deadline for asteroid tracking - Science Fair - USATODAY.com - 0 views

  • he panel finds the 2005 order to find 90% of Earth-threatening asteroids 460 feet or larger infeasible,
  • No method for diverting asteroids has been experimentally demonstrated
  • Options include a "gravity tractor" orbiting slow-moving objects and tugging them off course with tidal tugs, a "kinetic" impact of a heavy spacecraft into an asteroid, or a nuclear explosion
  • ...1 more annotation...
  • Unlike the dinosaurs, we are smart enough to do the math and figure out the answer that modest resources should be dedicated to the problem

      "we are smart enough" is a completely subjective comment. Reading the article it does not give the same impression :|

UNITED KINGDOM SPACE AGENCY UKSA (fake website) - 3 views

  •  
    according to the normal website (http://www.bnsc.gov.uk/): "The UK Space Agency website will officially launch on 1 April 2010. Until then, the BNSC website will be in a state of transition " the guys above i think just take the piss coz theres no official website. Mission statement: TOGETHER WE ARE GOING TO EMBARK ON A JOURNEY INTO SPACE. ..........................THE MISSION IS......MARS................................."
  •  
    I've just read a blog entry about this on New Scientist, and while the entry itself is not interesting, I learned from it where the UKSA and ESA's UK establishment are going to be based. Answer: it's even more in the middle of nowhere than Plymouth! BTW does anyone (Leo?) know what is the basis on which new ESA establishments locations are chosen (if this info is classified, you can send it on priv ;) [Edit] Esa has released a news item about it... Whatever one can say about the British Space Agency, they certainly have a fantastic logo!

How to quadruple your productivity with an army of student interns - 6 views

  •  
    Potential lessons for out own trainee program?
  •  
    well - part of it we already do ... e.g. : (did you see the picture in the report?) "Tolerate a little crowding. It took a little creativity to suddenly find a dozen new workspaces in our two-room office. Fortunately, we've found that a room can always fit one more person-and by induction, you can fit as many as you need. (All those years we spent proving math theorems came in handy after all.) "

The Semicolon Wars » American Scientist - 2 views

  •  
    Pretty interesting piece on computer languages.
  •  
    Yes, very good, but I don't get what all the fuss is about... everyone knows Python is the ultimate programming language! :) Follow up reading: If programming languages were religions... (quite accurate actually) Great quote from the article you linked to: In 1975 Edsger W. Dijkstra, a major figure in the structured-programming movement, wrote a memo titled "How Do We Tell Truths that Might Hurt?" The "truths" were mostly Dijkstra's opinions of programming languages; how he told them was very bluntly. Fortran is "an infantile disorder," PL/I "a fatal disease," APL "a mistake, carried through to perfection." Students exposed to COBOL "are mentally mutilated beyond hope of regeneration," he said. "The use of COBOL cripples the mind; its teaching should, therefore, be regarded as a criminal offense."

Russian Physicists Solve Radio Black-Out Problem for Re-Entering Spacecraft  - Technology Review - 1 views

  • When spacecraft return to Earth, one of the tensest parts of the mission is the radio black out that occurs as the vehicle re-enters the atmosphere. Travelling at hypersonic speeds of between Mach 8 and 15, the spacecraft heats and breaks down molecules in the atmosphere causing a plasma to form. It is this plasma sheath that prevents radio communication.

    we were 1,5 year ahead to switch to diigo !
  •  
    Man, I remember, long long time ago, altavista was my first contact with the internet ever.
  •  
    indeed ... and it was largely thanks to you ... remember well the discussion in the group meeting with the arguments brought forward: why change, it works ...

New Type Of Entanglement Allows "Teleportation in Time", Say Physicists - Technology Review - 1 views

  • Conventional entanglement links particles across space. Now physicists say a similar effect links particles through time.
