I thought the following may be of interest to the Balloons group.  Quite a
sophisticated flight package.

Subject: {WhiteStarAnnounce} Balloon Flight Announcement: White Star Flight
Today

 

I'm Proud to announce the first, and possibly only major flight of White
Star, our pride and joy, on the cutting edge of amateur science and
engineering, SpeedBall-1, "Lally":

 

Up to date info will be available here as launch time approaches:
http://whitestarballoon.com/?p=826   

Check there approximately 4 hours before launch for live audio and video of
prep.

We will have live streaming video and crew audio from mission control and
launch.  

 

 

Launch time: 7:45PM ET Saturday (2345 UTC 12 May)

Launch Location: Spaceport Indiana (KBAK Airport)

Cruise Altitude 70,000 ft  (We're movin' on up!)

Flight Duration Expected: 1-3 Days

Tracking page: http://track.whitestarballoon.com
<http://track.whitestarballoon.com/>   (note this may show (and be marked
as)simulated testing data up until about 5PM ET Saturday.

Balloon System: A hybrid floater, with a latex balloon doing the heavy
lifting to 21km altitude, far above the ZP's original design altitude of
10km.  The ZP will still provide the function of venting enough helium to
arrest the climb and establish a float.

Western with White-star designed one-way plate valve, featuring a silicone
seat, and PVC pipe port at the top for He temp sensor.

            54 Energizer Lithium AA Batteries

            5.5lbs of C2H6O ballast in a SNOX-copied ballast bottle

            Humidity Sensor

            Cloud particle sensor

            Temperature sensors

            Helium internal temperature sensor

            Raw battery pack voltage sensor

Estimated Ground Track:  Very slow progression through the midwestern USA
for several days if target altitude is reached.

 

Lift Helium is proudly provided by SpacePort Indiana, Praxair Gases, and
donors to White Star/LVL1
