Natick High Altitude Balloon–Successful Tethered Test

Successful tethered test! We didn’t launch (due to the cloud cover), but the test was great. With the large tank, the balloon filled quickly and easily. You can have pretty much any lift you want. We filled the balloon too much, and went off the 2 kg scale for lift. The last aspect we need to control is the amount of lift, and that’s pretty straightforward. At this point we’re ready to launch(!)
If you look at the picture full size you can see the parachute and instrument package up there. We had it 150ft up, and got good satellite and APRS data. 
To the Stars, and Beyond!
