Stevan Spremo is the project manager of COTSAT-1, or Cost Optimized Test of Spacecraft Avionics and Technologies. The ongoing development project aims to build a fully functional spacecraft for $500,000 in parts and $2 million labor. The prototype is the first of...

Dr. Patrick Fink leads technology development of radio frequency identification (RFID) systems. The RFID technology will support NASA's efforts to track its various inventories on the International Space Station, from personal supplies...

Using the Global Precipitation Measurement (GPM) Core Observatory satellite, launched in 2014, NASA and Japan Aerospace Exploration Agency researchers have taken the first 3D images of raindrops and snowflakes. The GPM snapshots will help research meteorologist...

On December 6, 2015, two small satellites, or CubeSats, successfully launched to the International Space Station. As part of NASA’s Nodes mission, the CubeSats will soon communicate with each other and demonstrate the benefits of a...

In 2020, NASA's first-ever integrated-photonics modem will be tested aboard the International Space Station. Mike Krainak leads the development of the modem, which integrates optics-based functions such as lasers, switches, and wires onto a microchip....

Jim Heidmann of Glenn Research Center (Cleveland, OH) and Jason Welstead of Langley Research Center (Hampton, VA) have led NASA efforts to develop all-electric and hybrid-electric designs for large passenger aircraft....

Convective weather, such as severe thunderstorm activity, is the leading cause of delay in the U.S. National Airspace System. Two NASA-developed tools – the Dynamic Weather Routes (DWR) tool...

Dr. Catharine A. Conley, Planetary Protection Officer, NASA Headquarters, Washington, DC

As NASA plans launches to Mars, Europa, and beyond, the agency's Office of Planetary Protection ensures that the environments are shielded against contamination, especially bacteria and microbes from Earth....

As NASA plans launches to Mars, Europa, and beyond, the agency's Office of Planetary Protection ensures that the environments are shielded against contamination, especially bacteria and microbes from Earth. Dr. Catherine Conley oversees and audits the...

Dr. Santo Padula has developed testing techniques to support the development of advanced materials like metallic foams and shape memory alloys (SMAs). SMAs are metals that “remember” their original shape. With the application of heat, a deformed SMA...

Al Bowers is the program manager of Preliminary Research Aerodynamic Design to Lower Drag, or Prandtl-d. The project’s researchers validated elements of a boomerang-shaped wing design that could greatly improve the efficiency of future aircraft.
