As of 11:40 p.m. on July 21, a launch scrub has been called. The next attempt will be Monday, July 23 with a window of 5-8 a.m.
Congrats!In case anybody was wondering what "a high-speed U.S. Navy Stiletto boat" is, it's this: http://en.wikipedia.org/wiki/M80_StilettoKinda bad-ass recovery ship.

"that would be perfectfor spacex recovery if they wanted to go with the whole dr. no/evil joke."On a more serious note, did they have to choose the Stiletto because they had only a vague idea where the craft would reenter and the Stiletto's speed gave them a huge range for recovery? Or do the Navy SEALS just have the day off so they decided to loan out one of their babies.
My favorite inflatable, Moose... Woohoo! Enjoy the ride! http://www.astronautix.com/craft/moose.htm
As of some time yesterday afternoon they hadn't recovered it yet. I'll ask around and see what I can find out though.

The surveillance plane spotted what they thought was it looking and directed them towards something but it ended up being part of or all of a derelict sailboat.After talking with some people on the project, recovery wasn't a primary objective so they aren't too upset by it. Also, I can confirm that in the mission readiness review document it was not listed as a requirement under minimum or comprehensive success.
IRVE was apparently initially designed "to enable the exploration of higher-altitude terrain on Mars" (http://www.newscientist.com/article/dn22094-inflatable-spacecraft-makes-successful-splash-landing.html)any reference for this?also, have a look at this very cool prez, with lots of technical details http://www.planetaryprobe.org/SessionFiles/Session6B/Presentations/7_Dillman_IRVE-3.pdf
jcm, thanks for having included the reentry speed of the inflatable reentry tests so far in your latest space report. it gives an idea of how much work remains to be done.you mention IRVE-3 reentry speed at about 2.7 km/s, which is much less than needed for LEO rentry (7 km/s), Mars landing (6-7 km/s) or hyperbolic reentry to Earth (>10 km/s)
"The 680-lb. flight demonstration payload lifted off at 7:01 a.m. EDT from Wallops Flight Facility atop a three-stage Black Brant sounding rocket that carried it to an altitude of 253 nm, where its onboard control system flipped it over and inflated its concentric-ring structure with nitrogen into a 10-ft.-dia. aeroshell covered with a four-layer thermal blanket.{snip}

That initiative could make possible returning several metric tons back to Earth from the International Space Station, making use of an aeroshell of some 26 feet to 32 feet (7.9 meters to 9.8 meters) in diameter.

Why did they resort to an expensive and ineffective surveillance plane?
