<h4>United States: Innovation in Aviation</h4>
<ul>
<li><B>Successful Test of Scramjet Propelled Aircraft:</b>  NASA, the U.S. Space Agency, performed the first successful test of an <a href="http://www.reuters.com/newsArticle.jhtml?type=scienceNews&storyID=4677867&section=news">aircraft propelled by a Scramjet engine</a>.  This test follows the successful <a href="http://www.newscientist.com/news/news.jsp?id=ns99992685">in-flight ignition</a> of a scramjet engine in 2002.  The <a href="http://www.tc.cornell.edu/Research/CMI/RLVsource/scramjets.html">SCRAMjet</a> (an acronym for Supersonic Combustion RAMjet) is the next major advancement in aerospace propulsion building on the successful technology of <a href="http://www.aviation-history.com/engines/ramjet.htm">RAMjets</a> (a proven technology used successfully on the <a href="http://www.wvi.com/~lelandh/srspec~1.htm">SR-71 blackbird</a> spyplane) which is itself a further advancement over traditional <a href="http://www.aviation-history.com/engines/theory.htm">JET power</a> propulsion technology.<p>The real achievement accomplished is being able to propel an aircraft to Mach 7 (Seven times the speed of sound, approximately 5000 miles per hour) without the use of <a href="http://www.aerospaceweb.org/question/propulsion/q0161.shtml">rocket technology</a>.  Whereas rockets carry their fuel and oxygen supply with them, Jet technology uses the oxygen supply from the atmosphere for combustion.  Also, rocket technology is a one-time use propulsion technology.  Rockets are costly and time-consuming to manufacture, require very precisely managed launch cycles and are in general a volatile and dangerous technology.  Basic jet-propulsion technology has been used commercially for decades.<p>SCRAMjets will hopefully open the commercialization of outer space by enabling vehicles that are cheaper to manufacture, easier to operate, have a higher fuel vs. payload ratio, and have a very fast flight turnaround time (much like commercial jet aircraft today).<p>Related Link: Wikipedia <a href="http://en.wikipedia.org/wiki/Aviation_history">Timeline of Aviation History</a>.

Mars Once Wet With Water

By now you've no doubt heard the news. For great BLOG commentary on this new update, TNFM recommends these sites:
Those in the business seem to be taking this latest science very seriously. The bookmaking firm Ladbrokes announced it's stopped taking bets on the question of whether there was ever life on Mars.

So now that you know the news are you ready to pack your bags and buy some nice martian "once beachfront" property? You may be too late. (Don't take them too seriously argue legal scholars.)

At least some people are getting a good tongue-in-cheek laugh from all the press about Mars Rovers: Seems this Canadian writer has already got a jump on America's "Mars Wars".

Closing out Mars talk for today, with all this news about water and the possibility of Martian life on Mars, how can we be sure that there are no Earthlings living on Mars?


Comet Hunter Away

ESA's Rosetta "comet hunter" spacecraft was launched yesterday from its launchpad in French Guiana. The spacecraft, named for the famous stone that helped European scientists translate Egyptian hieroglyphics, is on a 10-year mission to drop a probe on comet 67P/Churyumov-Gerasimenko. The comet is hypothesized to have been in orbit since the beginning of the solar system and the hope is that exploration of it will help "decipher" some of the mysteries of our solar system's development.

Mars Rover Opportunity Makes 'Significant' Finding

This is a wonderful article from the International Edition of Newsweek that succinctly recaps the recent announcements and activities around the world regarding human space flight and exploration of the cosmos. The insight into the political challenges facing the U.S. regarding sustaining a space exploration program over presidential administrations is a nice analysis.
