it's really cool to progressively see how things look higher and higher up from the school, and the way homes have settled around the terrain. neat stuff.
That was really great! This got such an amazing view of Central California, you can see so many features from Half Moon Bay to the Point Reyes Peninsula, the Sacramento Delta and the Sierra Nevada range. So cool, you picked a good day to do this! Amazing that you were able to recover the balloon after it touched back down in Sacramento!
Any still shot / closeup of the payload pallet? What gas did you use in the balloon? Any stats - max altitude, time to max, rate of ascent / descent (did the ballon pop?), time aloft, distance travelled, temp at diff alt?
The payload is similar to the one shown in twitter.com/NasaNovas/status/624746526665867264?s=20&t=5WSAHu6_bYCtB656RelGsA - a styrofoam cooler with pool noodles attached, and a parachute tied between the payload and the balloon. We used about 120 cu ft of helium. We didn't have an altimeter or thermometer but predicted burst altitude was about 29 km. Temperatures get down to -40 or so (and actually go up a bit as you cross the tropopause). Rate of ascent around 5 m/s and descent around 10 m/s. Ground track was around 70 miles.
I would LOVE to do this with my HS stem club! Would you be willing to chat sometime so I could pick your brain? I would love to have my ducks in a row before presenting to admin.
There's a Spot Trace GPS tracker in the payload. We ran a landing predictor ahead of time that gave an indication of where the balloon would go given wind forecasts, but our ascent rate was slower than anticipated and it landed quite far from where we anticipated.
Rather nice! Many thanks. (Class of '67)
That was incredible. I graduated from ECHS in 2002. ❤️🔥
That is AWESOME guys!! Great Job!!
So this is the "Chinese balloon" the government keeps talking about...

Really epic views as you got into space - launched right from El Cerrito!
Amazing adventure for the class and the balloon!

Looks great, well done!
How did you know where to retrieve the cameras? Did you know it will not land in the surrounding waters?

Nice
