Yorick 0 #76 February 17, 2012 Nice article in Wired: Would the Stratos Space Jump Be Similar to Reentry? http://www.wired.com/wiredscience/2012/02/would-the-stratos-space-jump-be-similar-to-reentry/ spoiler: no. "The 'perfect' parachute jump was thought to be one where the opening shock and touchdown were simultaneous" -Lyle Cameron, ~1965 --- Falling-With-Style.com Quote Share this post Link to post Share on other sites
JohnMitchell 14 #77 February 17, 2012 It's pretty obvious, if you think about it, that a skydiver from a balloon has a lot less energy than a similar mass reentering at 17-25K mph. But it was a very well done analysis. My math is not that good anymore. Quote Share this post Link to post Share on other sites
TampaPete 35 #78 February 18, 2012 The physics is spot on. If you remember the X prize competition (first civilian group to send a vehicle into orbit twice) Dick Rutan sent a plane just into space and bounced along the edge of the atmosphere surface until the vehicle speed reduced enough to fall back into the atmosphere. He used the basic theory of low speed = low heat on reentry. http://scaled.com/projects/tierone/spaceshipone_flies_again_within_14_days_-_wins_10m_x_prize Quote Share this post Link to post Share on other sites

linebckr83 3 #94 September 27, 2012 I was on KROW in Roswell all last week for flight testing. From our telemetry station you could see their camp pretty well. Apparently they have a couple trailers that can move a transportable building around. Pretty cool little mobile setup. We were using the other side of the runway because of wind directions, but the couple times were on that side we stopped to look. There wasn't much activity outside...a truck driving around every once in awhile. If it was busy I thought of trecking over there to check it out."Are you coming to the party?
