In the not too distant future, the traditional memory and storage hierarchy of may be replaced by a single Storage Class Memory (SCM) device integrated on or near the logic processor. Traditional magnetic hard drives, NAND flash, DRAM, and higher level caches (L2 and up) will be replaced with a single high performance memory device. The Storage Class Memory paradigm will require high speed (< 100...
The Minimum Scale Sample Acquisition and Caching (MinSAC) architecture has been developed to enable rover-based sample acquisition and caching while minimizing the system mass. The MinSAC architecture is a version of the previously developed Integrated Mars Sample Acquisition and Handling (IMSAH) architecture. The MinSAC implementation utilizes the sampling manipulator both for sampling and sample...
Planetary protection and organic contamination control, like many technologically rich areas, continually progress. As a result of the 2011 Planetary Science Decadal Survey Report, Vision and Voyages for Planetary Science in the Decade 2013-2022, the future focus is now on proposed Mars sample return missions. In addition to Mars exploration we now have the exciting possibility of a potential mission...
Liquid chromatography mass spectrometry (LC-MS) is an important laboratory technique for the detection and analysis of organic molecules with high sensitivity and selectivity. This approach has been especially fruitful in the analysis of nucleobases, amino acids, and measuring amino acid enantiomeric ratios in extraterrestrial materials. We are developing OASIS, Organics Analyzer for Sampling Icy...
This paper presents a research work on small satellite data stream and related distribution to associated stakeholders, which is a field that needs to get explored in more detail. The algorithm that is presented to extract USDDP (User-Specific Data Denominated Products) is a self managing body, which will be within as Open Space Box environment or OSBE as a novel idea. It contains an individual stream...
The tropospheric Infrared Mapping Spectrometers (TIMS) operating at 2.33 and 4.68 µm were developed to demonstrate retrieval of atmospheric CO in several layers. In this presentation we describe the architecture of the 2.33 TIMS spectrometer, recap its development, develop its noise model, and validate that against TIMS demonstration data. We briefly describe a multi-channel geostationary space application,...
There are over 40 subsystems being developed for the future SLS and Orion Launch Systems at Kennedy Space Center. These subsystems developed at the Kennedy Space Center Engineering Directorate follow a comprehensive design process which requires several different product deliverables during each phase of each of the subsystems. This Paper describes this process and gives an example of a subsystem...
Long duration spaceflight, permanent human presence on the Moon, and future human missions to Mars will require autonomous medical care to address both expected and unexpected risks. An integrated non-invasive visual field test & diagnosis system is presented for the identification, characterization, and automated classification of visual field defects caused by the spaceflight environment. This...
A crewed mission to Near-Earth Asteroids (NEAs) would maximize the quality and the amount of returned information regarding scientific, technological, mitigation or resource utilization purposes. To effectively prepare such a mission, a robotic precursor should visit the asteroid target(s) to ensure its relevance and safety.
Government supported nano-satellite launch programs and emerging commercial small satellite launch services are reducing the cost of access to space for educational and other CubeSat projects. The cost and complexity of designing and building these satellites remains a vexing complication for many would be CubeSat aspirants. The Open Prototype for Educational NanoSats (OPEN), a proposed nano-satellite...
In multisensor track fusion systems, according to the transmit or processing delay,the measurements can come to the fusion center out of sequence.In order to avoid either a delay in the output or the need for reordering and reprocessing an entire sequence of measurements, such measurements have to be processed as out-of-sequence measurements (OOSMs).Most of the algorithm dealing with OOSMs considered...
Caves on other planetary bodies offer sheltered habitat for future human explorers and numerous clues to a planet's past for scientists. While recent orbital imagery provides exciting new details about cave entrances on the Moon and Mars, the interiors of these caves are still unknown and not observable from orbit. Multi-robot teams offer unique solutions for exploration and modeling subsurface voids...
Papers published via IEEE and AIAA conferences have presented an overview of how social media could benefit NASA working environments in general [1] and proposed three specific social applications to benefit space flight control operations [2]. One of them, Communications Dashboard, would help a real time flight controller keep up with both the “big picture” and significant details of operations via...
This paper introduces RadioBOT, a flexible system of mobile robots for acquisition of radio frequency data. The motivation for such a test system is described, namely the difficulty in acquiring real world data for the purpose of spatial cognitive radio (CR) research. Some current areas of CR research are presented for which RadioBOT can gather data. We then describe the hardware and software components...
While hurricane track forecasts have improved in accuracy by ∼50% since 1990, there has been essentially no improvement in the accuracy of intensity prediction. This lack of progress is thought to be caused by inadequate observations and modeling of the inner core due to two causes: 1) much of the inner core ocean surface is obscured from conventional remote sensing instruments by intense precipitation...
Early detection of anomalies in any system or component prevents impending failures and enhances performance and availability. The complex architecture of electronics, the interdependency of component functionalities, and the miniaturization of most electronic systems make it difficult to detect and analyze anomalous behaviors. A Hidden Markov Model-based classification technique determines unobservable...
Set to fly in the Fall of 2013 from Ft. Sumner, NM, the High Energy Replicated Optics to Explore the Sun (HEROES) mission is a collaborative effort between the NASA Marshall Space Flight Center and the Goddard Space Flight Center to upgrade an existing payload, the High Energy Replicated Optics (HERO) balloon-borne telescope, to make unique scientific measurements of the Sun and astrophysical targets...
The development of avionics systems is typically a tedious and cumbersome process. In addition to the required functions, developers must consider various and often conflicting non-functional requirements such as safety, performance, and energy efficiency. Certainly, an integrated approach with a seamless design flow that is capable of requirementsmodelling and supporting refinement down to an actual...
This paper analyzes Initial GBAS GAST D availability at a set of current ILS CAT III airports. Eurocontrol Pegasus Availability Tool, designed for SESAR projects is used for the assessment. Overall availability of the GBAS GAST D system is considered, focusing on business aircraft specifics where applicable.
As wavefront control techniques continue to improve, coronagraphic imaging of exoplanets is becoming a promising technique for both ground and space observatories. The inherent sensitivity of a coronagraph to perturbations in the electric field means that residual quasi-static speckles appear in the image plane, constraining the relative brightness (or contrast) and angular separation of an exoplanet...
