Treasure Valley Near Space Program Inc (TVNSP Inc) will launch TV04B on
Saturday, September 4th at approx 7:15 am MDT (1415 UTC).
The flight will consist of 2 capsules flying under the TVNSP Inc call sign
NS7TV-1 and Dan Paulson's callsign KD7OST-11. The balloon will be a 1200
gram Kaysam. The expected burst altitude will be 103,000 feet or more.
The first capsule, NS7TV-1, will be flying an Alinco DJ-S11 with a TT3 and
Garmin GPS 35 LV on 144.39 MHz. This capsule will be Jeff's Camera Platform
and will also control the cut-away device for the balloon. The capsule will
carry a panoramic camera and is programmed to take photos of the balloon,
horizon, and the release of the second capsule.
The second capsule, KD7OST-11, which will be the first test of Dan's High
Altitude/Low Opening Freefall (HALO) recovery system (Project Icarus) will
also be flying a Alinco DJ-S11 with a TT3 with a Gecko GPS also on 144.39
MHz. This is likely to be the first and only flight of this hardware
configuration. We hope to implement this recovery technology into most if
not all of our future capsules.
This flight will have a single launch with separate recoveries for the two
capsules. The release capsule will be cut away upon a command from the
ground and will freefall to 20k where it will deploy it's parachute and
enter a normal recovery mode.
Photos of both of the capsules can be found at
The launch point is yet to be determined. Landing of both capsules will be
along the Owyhee front.
