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

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!

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.) "

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.
