We like to fly balloons and get them back or at least keep track of them in orbit. We launch high altitude balloons, predict where they'll land and track their flight and find the payloads by radio. We launch our balloonSats (pico balloons) which float at about 50,000 feet for weeks to months to years in orbit. We use solar powered radio beacons to track the balloons in orbit. We are always looking at new ways to build and launch out balloons and payloads.
