NASA’s Marshall Space Flight Center researchers have developed a new, stronger aluminum alloy, ideal for cast aluminum products that have powder or paint-baked thermal coatings. With advanced mechanical properties, the NASA-427 alloy shows greater tensile strength and increased...

New insulative carbon-fiber composite systems have been developed for use in structural and thermal applications for the aerospace vehicle interface. The sandwich-type composite structure, including carbon fiber and aerogel blanket materials, is based on the previously disclosed family of...

Minimally invasive and non-invasive therapeutic ultrasound treatments can be used to ablate, necrotize, and/or otherwise damage tissue. High-intensity focused ultrasound (HIFU), for example, is used to thermally or mechanically damage tissue....

There is a need to calculate the radiative heating rate at the surface of a vehicle entering any atmosphere, (e.g., Earth, Saturn, Titan, Mars, Venus etc). NEQAIR simulates the actual chemical and physical actions and reactions of the gaseous species in high-temperature shock...

This application serves as Web-based management of the Systems Engi - neering Education and Development (SEED) program, and enables the SEED Program Manager to track and manage the applications and assignments. In the past, the handling of the applications and assignments was...

Many software applications have scripting needs including those based on the Goddard Mission Services Evolution Center (GMSEC) framework. In GMSEC, a user may want to automate the actions to take when a sequence of events occurs. Ideally, the scripting solution should allow the use of a familiar programming language and avoid unnecessary...

An assessment of a system’s safety requirements is required early in the design process when cost and time impacts are minimal. These requirements include fault detection, failure isolation, and failure recovery. Systems engineering groups at NASA have been exploring model-based products to better...

The Sample Capture Mechanism (SCM) is a remotely actuated, spring-driven mechanism designed to remotely capture and seal a 15-mL sample in less than 1 second. It was used to capture a 10-g sample of simulated regolith dispensed from a drill in a...

Invasive surgical procedures are essential for addressing various medical conditions. When possible, minimally invasive procedures are preferred, but these technologies are often limited in scope and complexity. These limitations are due in part to mobility restrictions from the use of rigid tools in small...

Production of precision optical mirrors by replication requires molds or mandrels of the complementary shape. For example, replicating a concave mirror requires a convex mandrel. Convex shapes are difficult to fabricate and test since they do not focus light. Convex...
