The balloon
Balloon
A balloon is an inflatable flexible bag filled with a gas, such as helium, hydrogen, nitrous oxide, oxygen, or air. Modern balloons can be made from materials such as rubber, latex, polychloroprene, or a nylon fabric, while some early balloons were made of dried animal bladders, such as the pig...

Latex
Latex is the stable dispersion of polymer microparticles in an aqueous medium. Latexes may be natural or synthetic.Latex as found in nature is a milky fluid found in 10% of all flowering plants . It is a complex emulsion consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins,...

BEAR-1

On May 27, 2000, this helium-filled balloon with a payload of .977 kg, was launched from the Bremner airport, and reached an altitude of 31,762 meters (104,206 feet). This first flight was a test of the GPS receiver used, to ensure that the unit successfully reported location information above the 60,000 foot limit imposed upon manufacturers, as well as the payload enclosure and antenna system to be used for future flights. A Pooh Bear mascot was also included in the payload for luck.

BEAR-2

This balloon was launched from an outdoor skating rink at Sherwood Park, Alberta

 on August 5, 2000. It reached 30,322 meters (99,481 feet) before the balloon burst. It landed in the Battle River south of New Norway, but was successfully recovered. This payload contained the same tracking system as proven on BEAR-1, as well as a highly modified Icom IC-24AT handheld configured for crossband repeating. The radio was configured to receive on 446.100 MHz in the UHF band, and repeat the audio automatically on 146.520 MHz in the VHF band. Contacts were made with stations from Cold Lake, AB to Swift Current, SK as well as numerous contacts in the Edmonton, Red Deer, Calgary corridor in Alberta. A last minute addition to the payload was an inexpensive digital camera. This camera was found to cause interference with the crossband radio on board, and was therefore turned off for the flight. The hole in the payload container for the camera ended up becoming an entry point for water from the river, causing major damage to the onboard electronics. This flight was originally scheduled to fly on July 15, 2000, but was scrubbed early in the evening of July 14 due to a tornado touching down at Pine Lake
Pine Lake, Alberta Tornado
The Pine Lake, Alberta Tornado was a deadly tornado in central Alberta on July 14, 2000 that struck a campground and trailer park. Twelve people were killed, making it the first killer tornado in Canada since 1994 when a doctor was killed by an F2 tornado in Saint-Charles-sur-Richelieu, Quebec...

. Frequency and personnel resources were needed for disaster recovery efforts over the next few days dealing with the aftermath of the event which left 12 dead.

BEAR-3

Reaching 35,475 meters (116,387 feet), BEAR-3 has thus far achieved the highest altitude for the BEAR series of launches. This balloon was the first in the series to be filled with hydrogen instead of helium. The payload contained a Trimble Lassen iQ GPS, a Byonics Micro-Trak 300 and four AAA Lithium L92 Batteries. A custom payload enclosure was designed in an effort to attempt to produce an ultra light weight payload. A payload mass of 95.8 grams was achieved which puts it tied with the lightest payload in the Amateur Radio High Altitude Ballooning Records. This payload was recovered near Mundare, Alberta.

BEAR-4

The balloon was released on August 23, 2009. The flight duration was 3 hours 56 minutes and reached an altitude of 32,658 meters (107,145 feet). This flight was designed to lift a High Definition video camera to altitude, recording video from the entire flight for Tomoya Kamiko from Japan. Tomoya provided the camera, while the BEAR team provided the payload container, tracking hardware, parachute and balloon. This payload was recovered near Mannville, Alberta.

BEAR-5

Launch time and location has yet to be announced. The intended APRS tracker ID is VE6ATV-11 at 144.390 MHz. This launch will be another attempt at breaking the altitude record.
