Radiation in space poses threats for both astronauts and electronic equipment.nbsp; While it is relatively easy to shield against non-ionizing RF and microwave radiation, shielding against higher energy ionizing radiation ndash; gamma rays, protons, neutrons and galactic cosmic radiation (GCR) ndash; is much more challenging.nbsp; With longer missions to Jupiter or future manned missions and with ...

Proposed herein is a novel non-contact chromatic phase-measuring interferometric probe capable of measuring the surface form of a free-form telescope optic to nanometer, or even sub-nanometer, levels.nbsp; The probe retains all the benefits of a chromatic optical probe (i.e., large measurement range and small spot size) as well as the benefits of a phase-measuring interferometer (i.e., high accura ...

In recent years, industry and government have begun adopting Model Based Engineering (MBE) practices in an unprecedented way. No longer exclusively the domain of isolated experts, MBE has been implemented across the full product lifecycle. This success is, however, giving rise to new challenges. The ability to share disparate models across teams, organizational boundaries, and among communities of ...

The Surface Space Suit Boot (SSSB) is an advanced subsystem level project that addresses several issues in planetary boots including mobility, thermal protection, stability and comfort, and dust migration.nbsp; The SSSB leverages decades of Lunar boot development and includes an advanced ankle mobility joint, a unique closure system, next generation outer garment materials, and an advanced polymer ...

Zero-G Horizons Technologies (ZGHT) in partnership with Embry-Riddle Aeronautical University (ERAU) is developing a Spacecraft On-Orbit Advanced Refueling and Storage (SOARS) system. SOARS directly supports Moon to Mars Campaign (NASArsquo;s Space Policy Directive-1). The key innovation of SOARS enables the separation of liquid and gas in microgravity through our unique rotational settling technol ...

A new class of materials, called hierarchical materials, characterized by microstructure rich in features with different length scale, showing revolutionary properties, has emerged recently in multiple application areas, especially in the additivenbsp;manufactured metals and alloys. Similarly, recent advancement innbsp;process control abilities and novel manufacturing technologies have demonstrate ...

Windhover Labs proposes to create an Integrated Development Environment (IDE) to enable rapid software development of NASArsquo;s Core Flight System (CFS) projects by managing and auto generating flight software configuration and table data, integrating real time commands and telemetry, and providing an integrated scripting engine for testing. Open extensible, flight software combined with a highl ...

Frequency selective surfaces (FSSs) are periodic arrays of conductive elements/patches that cause a particular reflection response when illuminated with high frequency electromagnetic energy. nbsp;These arrays arenbsp;used for high frequency filters and in antenna applications.nbsp; We propose to use FSSs as multi-functional sensors. nbsp;FSS sensors are unpowered, low-profile (thin), wireless and ...

The proposed Phase II supports completion of the RINGS science missions on ISS using SVGS as real-time sensor for the EMFF maneuver. During Phase I, SVGS-based navigation of RINGS was developed and tested on a 3DOF ground-based platform, and mechanical and electrical integration of RINGS with the free-flying robotic platforms on ISS (Astrobee) was designed in detail. SVGS was deployed and tested o ...

This NASA sponsored STTR project will investigate methods for close-out of large, liquid rocket engine, nickel or stainless steel nozzle, coolant channels utilizing robotic laser and pulsed-arc additive manufacturing (AM)methods. Structural jacket to coolant channel land area interface strength will be quantified and metallurgical characterization completed.Process optimizations will be conducted ...
