Juan Vuletich from Cuis Smalltalk is working at Satellogic company (Buenos Aires). Back in 2013 the company launched "Captain Beto" (a.k.a. CubeBug-1), the first Argentine CubeSat.
Now as one of the earth-observing
companies who push for more-advanced science satellites they were mentioned also in this article from nature.com. Nice.
Juan helped design and build the hyperspectral cameras in satellites Fresco and Batata. And he wrote the geometric and spectral processing software. The geometric software (image rectification and correction), the most complex part of the processing, was written by him in Cuis Smalltalk, and runs in a Cuis Smalltalk + OpenCL application.
Always interesting to see where Smalltalk is used and what kind of things people built with the help of Smalltalk
