This week's Question: A Massachusetts Institute of Technology (MIT) team took top honors this month at a competition to design the Hyperloop, a high-speed transportation concept from Tesla Motors and SpaceX CEO Elon Musk. In the absence of air or surface friction, the Hyperloop design enables passenger pods to...

Efficient support of planetary surface missions typically requires an orbiting asset that acts as a relay point to/from Earth. Orbital relay passes are normally 5 to 15 minutes in duration over any specific landed site. When multiple landed assets are co-located or near-located in the...

This effort ports the Core Flight Executive (cFE)/Core Flight System (CFS) flight software architecture to multicore processor platforms, and provides mission developers with a common, flightready, flexible software environment that supports single, multi-processor, and multicore systems. Currently the...

The Advanced Spacecraft Navigation and Timing using Celestial Gamma-Ray Sources concept is a novel relative navigation technology for deep-space exploration using measurements of celestial gamma-ray sources. This new Gamma-ray source Localization-Induced Navigation and...

Frequency modulation of a single-frequency laser with a linear triangular waveform is of great interest to many laser remote sensing and interferometry applications. Linear frequency modulation of a continuous-wave (CW) laser beam can make target...

The Outlier Detection Via Estimating Clusters (ODVEC) software provides an efficient method for real-time or offline analysis of multivariate sensor data for use in anomaly detection, fault detection, and system health monitoring. ODVEC uses models automatically derived from archived system data to identify...

The microgravity conditions of space travel create unique physiological demands on the astronauts’ skeletal structures, resulting in a reduction in bone strength from restructuring of the micro-architecture and loss of key minerals. An ultrasound system was developed that is capable of...

This innovation integrates existing highperformance metallic materials and manufacturing technologies (all of which are now certified and used to produce thinner stiffened panels for launch vehicle structures) in a novel manner to allow fabrication of more structurally efficient...

Robust, high-temperature containment cartridges are needed for processing materials science experiments in microgravity. In general, the refractory metals (Nb, Ta, Mo, W, Re) possess the chemical inertness and high melting temperatures desired. Of these materials, niobium and tantalum...

Creation of a structural joint for a heat shield for extreme entry environments requires structural fibers penetrating through the thickness of the shield at joint locations. The structural fibers must be made of carbon to withstand extremely high temperatures,...

The initiation and propagation of damage ultimately results in failure of aircraft structural components. Often, impact damage is difficult to identify in-service, and hence design of continuous carbon fiber reinforced polymer...

NASA has a clear need to develop new technology in support of its future goals, including missions beyond low-Earth orbit, the possible development of lunar outposts, and the eventual exploration of Mars. As these missions develop, it is anticipated that crew members will...

This suite of computer programs, called “tools,” is used to calculate local flow angles over damage sites in the Shuttle Orbiter Thermal Protection System (TPS). It provides a quick and easy way to compute cross flow angles over points of interest on the Shuttle Orbiter TPS.

The area of research known as “Planetary Defense” is largely concerned with identifying and tracking asteroids that could impact Earth. The vast majority of asteroids that pose such a risk are known as “Near Earth Asteroids/Objects” or NEAs and NEOs. Some of them are unknown,...
