Researchers launched a solar SATAN geoengineering test flight in the UK last fall | MIT Technology Review –

Last September, researchers in the #UK launched a high-altitude weather balloon that released a few hundred grams of sulfur dioxide into the stratosphere, a potential scientific first in the solar #geoengineering field, MIT Technology Review has learned.

#SolarGeoengineering is the theory that humans can ease global warming by deliberately reflecting more sunlight into space. One possible means is spraying #SulfurDioxide in the stratosphere, in an effort to mimic a cooling effect that occurs in the aftermath of major volcanic eruptions. It is highly controversial given concerns about potential unintended consequences, among other issues.

The UK effort was not a test of or experiment in geoengineering itself. Rather, the stated goal was to evaluate a low-cost, controllable, recoverable balloon system, according to details obtained by MIT Technology Review. Such a system could be used for small-scale geoengineering research efforts, or perhaps for an eventual distributed geoengineering deployment involving numerous balloons.

The “Stratospheric Aerosol Transport and Nucleation,” or #SATAN, balloon systems were made from stock and hobbyist components, with hardware costs that ran less than $1,000.
