Lastly, additional functionality on this mission includes file transfer between CSP0 and CSP1. Images products can be selectively processed with a variety of image processing techniques including edge enhancement and compression. The design enables a unique scalability by varying the size of the cold plates from lab-on-a-chip devices to application on large satellites. 1) What is the current global baseline distribution of CH4 in the atmosphere? Commercial devices have the energy and performance benefits of the latest technology but are susceptible to radiation in space, whereas radiation-hardened devices are relatively immune to radiation but are more expensive, larger, and outdated in both speed and functionality. The larger bubbles and TIDs (Traveling Ionospheric Disturbances) can span hundreds or even thousands of kilometers and can cause errors in differential navigation solutions. The 18 Mbit SRAM incorporates EDAC and an automatic read and write back which effectively scrubs the memory if the entire memory space is read. Since applications are implemented using the system's overlays rather than directly using FPGA resources, security policies can be enforced by restricting the capabilities provided by this overlay library. The frequency of upsets can be correlated to the environment through STP-H5 RHEME's dosimeter sensor developed by RMD (Radiation Monitoring Devices). The identification and frequency of occurrence of multiple bit upsets from a single heavy ion strike are especially interesting. 12) 13). Our codification algorithms are implemented through proprietary techniques that guarantee optimal performance. Many future exploration missions have to robotically or autonomously dock, capture, or land on exploration sites, whether those sites are other spacecraft, orbital outposts, asteroids, comets, or planetary moons. For future space-processing missions, it may become necessary for processing tasks to be completed autonomously. The loss of this information can cause the electronics to malfunction and jeopardize the mission. COTS (Commercial-off-the-Shelf) hardware are assessed for reliability in a harsh operating environment for long term performance changes that may impact scientific results. The CSPv1 allows multiple applications to be performed in the FPGA fabric without reconfiguring the entire device. All data is collected and inventoried in such a way that distribution is possible to SHM collaborators to investigate alternative approaches. Mechanical parts are replaced by electrodes that deliver the voltage needed to move the coolant. Results provide new methods for determining various ways in which equipment fails, from bolts that have jostled loose to debris impacts. Working in collaboration with the NASA/GSFC SpaceCube team, researchers in the NSF Center for High-Performance and Reconfigurable Computing (CHREC) at Florida and BYU are developing hybrid space computers that feature an innovative combination of three technologies: COTS devices; radiation-hardened (RadHard) devices; and fault-tolerant computing. This feature provides a spectrum of combinations to scale cost and reliability for different requirements. LITES measures the intensity of ultraviolet airglow that occurs naturally due to photochemical processes in the upper atmosphere. Together, the two will deliver tomographic measurements of the ionosphere at a 20 km vertical and horizontal resolution. The global sink of CH4 occurs largely in chemical reaction with OH molecules with little trend over the last few decades . SCH is used mostly to schedule telemetry requests to our applications. These images are in a read-only partition of the flash. Raven also reuses the flash lidar flown as part of the Sensor Test for RelNav Risk Mitigation (STORRM) demonstration on STS-134. It is designed to tolerate space radiation, which can damage computer systems, and to minimize energy use and cost. that may occur during the assembly, integration and testing operations to on-orbit missions. Note: Radiation tolerant –susceptible to radiation induced upsets (bit flips) but not radiation induced destructive failures (latch-up), • Accept that radiation induced upsets will happen occasionally .... and just deal with them, • Target 10 x to 100 x improvement in "MIPS/watt", • Hybrid processing .... CPU, DSP and FPGA logic, • Integrated "radiation upset mitigation" techniques, • SpaceCube"core software" infrastructure, • Small "critical function" manager/watchdog, Note: SpaceCube 2.0 and SpaceCube Mini can be populated with either commercial Virtex5 FX130T parts or radiation hardened Virtex5 QV parts .... offering system developers the option of trading computing performance for radiation performance, Figure 2: Commercial processor trend (image credit: NASA, DoD), Figure 3: Space processor trend (image credit: NASA, DoD), Figure 4: SpaceCube closes the gap (image credit: NASA, DoD), Figure 5: SpaceCube family overview (image credit: NASA, DoD), Figure 6: Illustration of STP-H5 assembly accommodation on ISS (image credit: DoD Space Test Program), Figure 7: STP-H5 configuration overview (image credit: NASA, DoD, Ref. The solution to the decrease in Earth-observing missions is to develop more small satellites, with high-processing capability. This concept is illustrated in Figure 10. The Random Vibration Test was performed unpowered, with a sine sweep prior to and after each axis. One of the main challenges for incorporating an FPGA device in a spacecraft system stems from the SRAM-based memory architecture, which makes it susceptible to SEEs (Single-Event Effects). Figure 20: Front view of the RHEME flight experiment prior to lid attachment (image credit: UNM (University of New Mexico), COSMIAC Research Center). Figure 11 shows a populated board using all-COTS components, where the unpopulated regions are for the placement of equivalent radiation-hardened components. The Space Test Program-H5-Spacecraft Structural Health Monitoring investigation (STP-H5 -SHM) captures how the fasteners, glue and mechanical parts on the Space Test Program equipment change from its assembly, testing and arrival in orbit. Figure 24: The STP-H5 Group-C Experiment (image credit: NRL). The workmanship vibration test of the ISEM assembly was performed successfully on all three axes, with no significant changes detected during the sine sweeps.
