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.
In 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.

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.
Advanced Materials Applications, LLC (AMA) is pleased to announce our name change to Yosemite Space. This change reflects our primary focus on developing innovative products for Space applications. In late October 2014, a Yosemite Space experiment using state of the art System on Chip (SoC) technology will be deployed in the NanoRacks External Platform outside the International Space Station. This platform will expose the components to space radiation and communicate the status of the Yosemite Space payload back to Earth. Information on computing performance will be used by Yosemite Space to develop next generation reliable computers.
The Yosemite Space logo was inspired by the Space.com photograph of the International Space Station traveling across the night sky above the spectacular landmark Half Dome.
Special Update: Our payload was bumped from the Oct. 2014 flight. Final flight date is still pending.
Jeremy Zawodny of AMA traveled to Houston in early July of this year to work with Astrium of North America and NanoRacks on the integration of our boards into the NanoRacks External Platform (NREP). The primary goals of testing were to confirm AMA’s communication software was compatible with the NREP Command Data and Handling (CDH). Testing was successful.
Our payload will transmit information on single event effects during the space mission through the NREP health and status reporting and the medium rate telemetry stream. As a result, AMA can retrieve this rate semi-real-time back on Earth.
Dr. Morse of AMA spoke at the NASA Digital Learning Network in March 2014. She discussed the space-friendly nature of current generation cell phone processors with high school students from across the U.S.. She explained how terrestrial electronics can be protected from the space radiation environment and provides a powerful computing platform for space applications.
Dr. Kathleen Morse poses this question to high school students across the U.S. as part of the CASIS and NASA sponsored Digital Learning Network program.
During the chat, ask Dr. Morse your question by sending it via email email@example.com or tweet the question with #askDLN.
The hourlong event will be webcast on the NASA DLiNfo Channel on March 5, 2014, at 2 p.m. EST.

Dr. Kathleen Morse is to speak at the Third International Workshop on Lunar Cubes this November 15th in Palo Alto, CA.
She will discuss the progress that AMA is making towards understanding how current generation system on a chip (SoC) technology behaves in a radiation environment. In addition, she will provide updates on the SoC payload scheduled to arrive on the external module of the ISS September 2014.
AMA looks forward to learning of the electronics requirements of Deep Space CubeSats and how we can work with customers to help them meet their exploration goals.
She will speak on AMA’s plans to evaluate the performance of Gumstix™ system on a chip in ground based and space based radiation studies. Ground based radiation studies will take place at Crocker Nuclear Labs from July to December of this year. Space based studies will occur on an external module of the International Space Station.
The ground and space based radiation studies of the Gumstix™ module will be the first published studies of its kind. This will be an initial and an important first step to integrate this powerful system on a chip technology into future radiation tolerant computers.

An excerpt from the abstract of the proposal is provided below.:
Radiation hardened and radiation tolerant computers do not offer an optimum processing solution for space applications that are computationally demanding such as signal processing and analysis, data capture, and sensing and detection. Current space qualified computers use processors that are 2 or 3 generations behind the state-of-the-art terrestrial processing technologies. Advanced Materials Applications, LLC (AMA) proposes ground based and space based radiation studies to investigate the feasibility of the Gumstix™ Computer On Module (COM) technology for use in non-critical computationally intensive space applications. Gumstix™ modules are gum stick sized and use current generation OMAP processors with ARM Cortex-A8 architecture. The proposed study is an important step towards their use in a fault tolerant computers that could meet the computational demands of current and next generation space missions.
