The BHALDI Team and The Works plan to launch 2 weather balloons into near space! Each balloon will carry a payload consisting of still cameras, HD video cameras, and other data capturing equipment such as thermometers, altimeters, barometers… possibly even a Geiger counter. The balloons will travel to an altitude of over 90,000 ft (17 miles!) before the balloons pop and parachutes bring the payloads back to earth. Each payload will include GPS tracking devices that will transmit their location to a website where everyone can track each balloon’s progress and see where it lands!

The Works is inviting interested families to come and participate in the launch and other science and engineering activities. Prior to launch, the launch team will conduct ademonstration of how the balloons, parachutes, and payloads are assembled and how the team determines howmuch helium to use. The launch team also will show a map that predicts the path of the balloon from launch to landing. After the launch, our launch team will set out to retrieve the balloons (they will likely land a couple hours away in Wisconsin), and families can follow the balloons in real-time and get reports from the retrieval team via Mission Control. This is the perfect opportunity for families to participate in an innovative hands-on project! Coordinated by B.H.A.L.D.I. and The Friends of The Works with support from the University of Minnesota Aerospace Engineering and Mechanics Department.

1st Launch: Halloween 2010

On Halloween 2010 the BHALDI team launched its first 2 systems, BHALDI I and BHALDI II:

BHALDI I

  • Weather Balloon
  • Parachute
  • Styrofoam cooler containing:
  • Kodak Zx3 HD Video Camera
  • Auxiliary battery for camera connected via USB
  • SPOT GPS Messenger tracking beacon
  • Chemical handwarmers to keep electronics warm
  • BHALDI II

  • Weather Balloon
  • Parachute
  • Styrofoam cooler containing:
  • 2 Canon cameras,each taking pictures every 10 seconds
  • SPOT GPS Messenger tracking beacon
  • Chemical handwarmers to keep electronics warm
  • We retrieved BHALDI II late in the afternoon from a resident of rural WI near Arcadia, north and east of Winona MN.  We located BHALDI I a bit west of BHALDI II, but were unable to retrieve it that day and had to return 2 days later, eventually cutting down the small diameter tree it had landed in.

    Despite difficulty retrieving BHALDI I, the launch was a huge success!  Click here to access more video on the BHALDI YouTube Channel and here for links to more pictures.
