Near-Space
Balloon Projects

Project Eos

As part of The Bay School's immersive program, our "atmospheric science and engineering" students take a three-week course in which they refine their understanding of Earth's atmosphere experimentally, designing and releasing balloon payloads to record data about different characteristics of the atmosphere. Eos I took flight in 2019. Eos II flew in 2021. Eos III flew in 2022. Eos IV flew on June 7, 2023.

Project Rahu

Bay School faculty Craig Butz and David Friedlander-Holm spent Summer 2017 preparing a flock of four weather balloons that were launched into the path of the total solar eclipse over Madras, OR on August 21st.

Project Ikaros

Between 2010 and 2013, students at The Bay School of San Francisco successfully launched and recovered four near-space balloon payloads, sailing into the stratosphere and returning atmostpheric data, photos, and video.

Ikaros I

Our first mission in May of 2010 proved that we could successfully launch and recover video and data from the upper atmosphere.

Ikaros II

Refining our first design, Ikaros II tested new components and a multi-package arrangement.

Ikaros III

With a new, lighter, more stable payload, including electronics we constructed ourselves, Ikaros III tweeted its way to 96,000 feet on April 11, 2012.

Ikaros IV

The flight of Ikaros IV, configured with better cameras, data-logging capability, and a bacteria collection device, was completed on April 11, 2013.
