Michelle Munk, Principal Investigator, Langley Research Center, Hampton, VA

Michelle Munk is Entry, Descent and Landing Principal Investigator for the Space Technology Mission Directorate. Most recently, Munk was the subsystem lead and the Deputy Project Manager for the Mars Science Laboratory Entry, Descent, and Landing Instrumentation (MEDLI) flight payload. NASA Tech Briefs: What is MEDLI? Michelle Munk: MEDLI is an instrumentation system that was put on the heat shield of the Mars Science Laboratory. It measured the pressure and temperature of the front face of the vehicle as it flew through the Martian atmosphere to land Curiosity on the surface.

Tom Flatley, Computer Engineer, Goddard Space Flight Center, Greenbelt, MD

Tom Flatley, computer engineer and current head of the Science Data Processing Branch at Goddard Space Flight Center, leads a group of engineers and programmers in their development of flight and ground-based science data processing systems and applications, including SpaceCube, CubeSats/SmallSats, modeling/simulation/visualization, and other technologies. NASA Tech Briefs: Why will NASA require improvements in on-board computing power? Tom Flatley: Many of the next-generation instruments currently being developed are going to produce tremendous data volumes, and at extremely high data rates. Their needs are surpassing the capabilities of current flight processing systems, so what we’re trying to do is enable an order of magnitude or more improvement in on-board processing power so that we can handle the large data volumes and high data rates that the next generation of missions will require.

David Wing, Air Traffic Management Researcher, Langley Research Center, Hampton VA

David Wing is the principal investigator for the Traffic Aware Strategic Aircrew Requests (TASAR) concept and software application. The cockpit technology, while taking aircraft traffic, weather, and other data sources into account, will compute trajectory changes during the flight to save pilots time and fuel. NASA Tech Briefs: What is TASAR? David Wing: TASAR is a near-term concept for improving aircraft operations that we’ve developed at NASA Langley. It stands for Traffic Aware Strategic Aircrew Requests. Basically, it’s putting technology on the aircraft in the cockpit that is monitoring the aircraft’s route of flight, and looking for opportunities to optimize that route with lateral and/or vertical changes, either to save time or save fuel or both. And in the process, it’s looking at the environment around the aircraft. First and foremost, we’re focusing on traffic awareness. Using airborne surveillance technology, such as ADS-B [Automatic Dependent Surveillance Broadcast], which is a technology where aircraft broadcast their position over a data link,a TASAR-equipped aircraft can receive and process the positions of other aircraft in the vicinity. The cockpit technology takes that data into account when computing optimum trajectory changes, to ensure those changes don’t interfere with the nearby traffic.
