Almost forgot this week! *1 billion stars in one image!*
Massive, 150,000 megapixel compost infrared image of the galactic plane! Over 1 billion stars are in the full size image, which is only 1% of the stars in our galaxy. http://blogs.discovermagazine.com/badastronomy/2012/04/04/to-grasp-a-billion-stars/ *Replacing some FRSI on the Shuttle* The Felt Reusable Surface Insulation (FRSI) is a nomex foam that covers the top side of the orbiter to shield the aluminium skin from thermal effects. Some photos of replacing a small piece of it. https://plus.google.com/116992234810067730471/posts/K1Z8eb56SAJ *Mercury Battered by Solar Wind* Planet Mercury imaged with massive particle outflows surrounding and impacting it. http://www.universetoday.com/94490/watch-mercury-get-smacked-by-cmes/ *Orion Parachute Test* Boeing's capsule "Orion" being drop tested. http://www.youtube.com/watch?feature=player_embedded&v=lvBa5Oiej_U *Copenhagen Suborbital's Crazy Huge Engine* CSS is upping the crazy by building a ~65-90 kN liquid (alchohol LOX) engine. Here is an almost 20 minute walk-through. [My Notes: I don't like the fact that it's He blow down, but it is simple and the He heat exchanger is a great idea. A combo of regen and film cooled nozzle is also cive and should give plenty of cooling for reuse of the engine.] http://www.youtube.com/watch?v=bqASqda0ylc _______________________________________________ psas-team mailing list [email protected] http://lists.psas.pdx.edu/mailman/listinfo/psas-team This list's membership is automatically generated from the memberships of the psas-airframe, psas-avionics, and psas-general mail lists.
