Yosemite Space Competes in NASA’s 3D Habitat Challenge

Yosemite Space joins the Artemis team to compete in NASA’s 3D Habitat Challenge.  Yosemite Space analyzed the radiation environment inside and outside the habitat.  Yosemite Space also contributed to radiation shielding design and mechanical analysis.

Yosemite Space Speaks at Single Event Effects Symposium

SEE imageIn late May of this year, Yosemite Space presented analyzed radiation data from ground radiation testing of three models of Gumstix: Earth, SandStorm and Water at the Single Event Effects Symposium.  Expected rates for single event effects in low earth orbit were presented.  Yosemite Space also showed that almost all Gumstix showed stuck bits in RAM when exposed to 64MeV protons.  Further testing indicated that this was likely due to microdosing.  Experience and knowledge from these tests are influencing the design of the Resilient Affordable Cubesat Processor.

Data from ground testing will be compared to space data once the Yosemite Space Gumstix payload is launched to the ISS and placed in the NanoRacks External Platform.  This s expected to occur in 2016.

Yosemite Space competes in the NASA Cube Quest

MILES conops

Earlier this year, Yosemite Space joined Team Miles to compete for the Cube Quest.  Yosemite Space is contributing to radiation shielding and mitigation, structure and command and data handling.  Team Miles will fly Yosemite Space’s Resilient Affordable Cubesat Processor (RACP) if Team Miles is selected in GT4 for a space flight.  RACP is currently at TRL 4.
