Launching a balloon and not landing in the ocean

balloon

In just a few short hours, the Yale Undergraduate Aerospace Association will launch their 4th high altitude balloon project into the rarefied air of the stratosphere and with any luck bring back pictures of the view high above Connecticut  Long Island, Rhode Island, and Martha's Vineyard. Inside their surprisingly strong unibody chassis is two GoPro cameras and a triple-redundant … [Read more...]

Checking out Mount Olympus from 38 km

olympus

The image above shows Mount Olympus in the center, with a tiny bit of the western suburbs of Thessaloniki, the second largest city in Greece, in the lower right hand corner. These two points are 70 kilometers apart, but we're not seeing a picture taken from the International Space Station. This is a picture from the SlaRos project, a high altitude balloon launched last summer that ascended to 38 … [Read more...]

Sending a Raspberry Pi to 130,000 feet

pi

We knew this wouldn't take long. [David] sent a high altitude balloon into the upper atmosphere last weekend using a Raspberry Pi as the brains of the payload. [David]'s payload consisted of a Raspberry Pi, natch, with a Logitech webcam, GPS receiver, and six AA batteries wired into a LDO regulator with a monstrous heat sink to keep everything in the EPX foam enclosure relatively warm in … [Read more...]

Beating the wrong amateur balloon record

Wrong

Friday, we covered a little project that attempted to beat the UK altitude record for an amateur balloon launch. Things don't always go as planned, but the APEX team did manage to beat the several other UK records, including ones for the longest distance and flight duration for a latex balloon. The APEX team was originally trying to beat the altitude record set by [Darkside] and his Horus 15.5 … [Read more...]

Going for the amateur balloon altitude record

sunrise

At 11 AM London time, October 22, the Sutton grammar school for boys is going to be launching Apex Alpha, a high altitude amateur balloon for an attempt at the UK altitude record. Unlike a few other balloons we've seen, the Apex team is doing it right and giving everyone the downlink details for the balloon. The payload for the balloon was built entirely by student of the Sutton grammar school … [Read more...]

Play-by-play of a high altitude balloon flight

horizon

[Greg Intermaggio] and [Shumit DasGupta] at Techsplosion launched a high altitude balloon last week that climbed to 90,000 feet above sea level somewhere over California. The play-by-play of the flight is one of the better stories we've seen on high altitude balloon builds. The balloon, christened VGER-1, carried a SPOT satellite GPS messanger to send telemetry back to the ground. We've … [Read more...]

Live high altitude balloon launch

On a related note, how come no matter how much helium you put in a tank, it will not float? (Hint: it has to do with density)

[Terry] is planning to launch his high altitude balloon within the next few days. As we've seen before he has gone for a general setup - GPS tracking, environment sensors including temperature and humidity and pressure, and 2 on board cameras - all with an expected height of about 100,000 feet. What makes this project unique is the transmission of live telemetry data to a Google Maps or Google … [Read more...]
