    We have recovered our HAB! It landed in a pond in Maine. Fortunately, Jamey, KC1ENX and Curtis, N1CMD had Jamey’s kayak and were able to retrieve it. The equipment is wet but appears to be in good condition. We have all of the HAB telemetry data and we will be analyzing that along with our students later this week.

    We broke our previous altitude record by A LOT! The balloon burst at over 117,000 ft! This is more the 25,000 ft higher than the last flight!

    Our flight path prediction matched our modeling quite well. The shape of the path was almost the same as what our model predicted but the flight took longer and went higher than we expected.

    Due to a glitch at launch, the platform flew on its side for the entire flight but we did get some video from the first 50 minutes of the flight. More pictures and video to come later in the week.

    Congratulations to our HAB Team and to our students for their successful launch!

    Congratulations on a unique flight and successful recovery. I was able to watch part of it on my computer while I was up north. For a while it looked like it would come down near Rochester, but must have been picked up by strong winds when it said it was traveling at 70+ MPH. Last location noted was near the 3 lakes or ponds in Maine… I was hoping it could have landed on the island or continue past the water. Last elevation I recall was about 1600 ft ASL.

    Even with the reported problem it was a good learning experience for the students and they still have all of the telemetry data to analyze… They must be excited and hopefully will share their experience with their classmates…

    Bet they’ll all reach “new heights” with their education. Perhaps we’ll encourage some of the students to join the ranks of Amateur Radio.

    73’s and great job all!

    Great work! While I could not participate, I did alert several hams in the Rochester and Southern Maine area thru the DMR net. They followed on aprs.fi and watched the sky! Glad the local digipeaters could follow it down to 1500′.

    We had a chance to look at the data recorded by HAB-2’s flight computer today. Here’s some data from the actual burst –

    • Max. Altitude: 35,955 m (117,962 ft)
    • Pressure At Burst: 0.73 mB ( < 1% of pressure at launch)
    • Temperature At Burst: -1.1 C (30 F)
    • Coldest Temperature Recorded: -56.6 C (-70 F) @ ~47,000 ft during decent

    We experienced significantly colder temperatures compared to our last flight and we see evidence of temperature impacts on the camera batteries and the Flight Computer GPS. More to come as well look at the data.

    Congratulations on a job well done!  Neat idea using APRS to send position data.  I remember using a Tiny Tracker 3 APRS interfaced with my HT to lof the “bread crumbs” on my commute to/from work.  I could see where traffic bunched up and where things were moving nicely.

    Given the band conditions this weekend, I should have paid more attention to the HAB flight instead of the CQ SSB contest, hi.
