*01 January 2023* *Make Sunsets * We plan to fly at least *3 balloons in January 2023.* Here's some details. *Anyone can comment here* ( https://docs.google.com/document/u/0/d/1vpPNk7f2yOzbX0UdaBDgGj-7gzObm2ZMy6RM_bWx5lA/mobilebasic), and *we'll consider input before finalizing launch plans!* *Where/When*: Southern Baja, Mexico. We'll plan exact location based on weather conditions, utilizing *SondeHub Predictor* (https://predict.sondehub.org/) to decide exactly where and when. Target will be near a road but away from any population center. *Balloons:* These flights will be latex weather balloons rated at 1200g. *Lift Gas:* These flights will utilize helium. *Clouds:* We will utilize sulfur dioxide generated by burning sulfur in the presence of oxygen. Each launch will include between 10g and 500g of clouds (target 100g+). *Target altitude:* We will use a *balloon performance calculator* ( http://tools.highaltitudescience.com/#) to inflate such that we're likely to achieve a burst altitude of ~33km. *Flight Body: * We're running *this body* ( https://www.highaltitudescience.com/products/eagle-pro-near-space-kit), and we'll likely add pool noodles for floatation (in case of a water landing). *Telemetry*: We're including *this flight computer* ( https://www.highaltitudescience.com/collections/electronics/products/eagle-flight-computer) as well as a Spot tracker. Note that the *Spot tracker* ( https://www.findmespot.com/en-us/) cuts out at 18km and the flight computer isn't transmitting data, so we'll only get full detail if we recover the balloon. Additionally, we'll be flying a camera. *Publication*: Within a week of each flight, we will publish all data obtained on our website. Next Round (after January flights), priorities to add include: - *Swarm* (https://www.sparkfun.com/products/19236) for data transmission during flight -waterproof + buoyant flight body -separate "cloud" chamber that vents at target altitude -partial balloon venting at target altitude -lighter camera and/or flights without -switch to hydrogen (if we can safely flare at altitude or otherwise deal with GHG implications). *Source: Make Sunsets* -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
