It looks like our GGreg20_V3 DIY Geiger counter module has a chance to join the Klo-01 stratospheric probe as part of the COMETA student educational project (Uruguay).

The project is complex and currently in preparation; the payload of the probe is not yet finalized and may still change. We’re keeping our fingers crossed that everything goes as planned by the project creators.

We once tested the module at low temperatures, but we couldn’t even dream of launching it into the stratosphere.
