SEA5: Space Environment Automated Alerts & Anomaly Analysis Assistant

Goddard Space Flight Center, Greenbelt, Maryland The Community Coordinated Modeling Center (CCMC) provides a wide range of space weather tools and services for the general scientific community. One such product that facilitates space weather situational awareness is collectively known as the Integrated Space Weather Analysis (ISWA) System. Using the ISWA system and other tools, space weather forecasters are able to assess the space environment in both real time and for historical cases — both of which help mitigate potential space weather impacts on missions, as well as assist in spacecraft anomaly resolution. The Space Environment Automated Alerts & Anomaly Analysis Assistant (SEA5) will provide past, present, and predicted space environment information for specific missions, orbits, and user-specified locations throughout the heliosphere, geospace, and on the ground.

Scenario Power Load Analysis Tool (SPLAT) MagicDraw Plug-in

The SPLAT tool could be applied to any project that needs to track time-dependent power consumption; it computes power usage profiles based on modeled component information and scenarios. NASA’s Jet Propulsion Laboratory, Pasadena, California Power consumption during all phases of spacecraft flight is of great interest to the aerospace community. As a result, significant analysis effort is exerted by both system and electrical-domain engineers to understand the rates of electrical energy generation and consumption under many operational scenarios of the system. Previously, no standard tool existed for creating and maintaining a Power Equipment List (PEL) of spacecraft components that consume power, and no standard tool existed for generating power load profiles based on this PEL information during mission design phases. Projects have traditionally either developed ad-hoc spreadsheet-based tools, or adapted complex simulation tools to compute such resource predictions; both of these approaches have significant limitations.

Cyclops: the Space Station Integrated Kinetic Launcher for Orbital Payload Systems (SSIKLOPS)

Lyndon B. Johnson Space Center, Houston, Texas The Space Station Integrated Kinetic Launcher for Orbital Payload Systems (SSIKLOPS), also known as “Cyclops,” deployed the largest satellite ever from the International Space Station (ISS) on November 28, 2014. The satellite, SpinSat, a Naval Research Laboratory (NRL)/Department of Defense Space Test Program (DoD STP) satellite, is pioneering the utilization of electronically controlled solid propellant thrusters as well as acquiring vital atmospheric density data. It is a spherical satellite 22 inches in diameter, weighing 115 pounds, and will remain in orbit for over two years.

Constraint Force Equation (CFE) Solver for Multi-Body Dynamics and its Implementation in POST2

Langley Research Center, Hampton, Virginia Existing aerospace flight trajectory programs simulate the motion of aerospace vehicles by modeling external forces and moments acting on each body, but lack provisions for determining reaction forces and moments exerted by one body on another through a connecting joint. These reaction forces and moments are also known as constraint forces and moments because they permit specified motion of one body relative to another, and, at the same time, prohibit all other relative motions. In other words, a joint imposes certain constraints on relative motion.

Aerogel Hybrid Composite Materials: Designs and Testing for Multifunctional Applications

NASA has a history of collaboration with industry for the development of aerogels in different forms. Scientists at KSC have continued to expand the design, development, and applicability of using aerogels by developing advanced composite materials and systems with multi-functional capabilities. Hybrid composite systems include aerogel/polymer composites (AeroPlastic), aerogel/foam composites (AeroFoam), and aerogel/fiber laminate systems (AeroFiber).

Signal Digitizer and Cross-Correlation ASIC

The device can correlate outputs from a large number of receivers. NASA’s Jet Propulsion Laboratory, Pasadena, California Microwave interferometry provides a means of synthesizing large scanning antennas that are not otherwise physically practical for spaceborne Earth observational systems. By cross-correlating multiple receivers of an array, high-resolution images are synthesized from a sparse — or thinned — array of small antennas rather than relying on extremely large mechanically scanned antennas. For Earth observations from space, high-datarate cross correlators are required that operate with low power and have low mass and complexity. ASIC (application-specific integrated circuit) cross-correlators are an enabling technology for space-based interferometry. An ASIC CMOS (complementary metal-oxide semiconductor) cross-correlator was developed to correlate outputs from a large number of receivers.
