Topic: Carbon NanotubesWritten by Lori Keesey
Mahmooda Sultana won funding to advance a potentially revolutionary, nanomaterial-based detector platform. The technology is capable of sensing everything from minute concentrations of gases and vapor, atmospheric pressure and temperature, and then transmitting that data via a wireless antenna — all from the same self-contained platform that measures just two-by-three-inches in size. Under a $2 million technology development award, Sultana and her team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, will spend the next two years advancing the autonomous multifunctional sensor platform. ![]() Technologist Mahmooda Sultana holds an early iteration of an autonomous multifunctional sensor platform, which could benefit all of NASA’s major scientific disciplines and efforts to send humans to the Moon and Mars.

NASA looks to use Carbon Nanotube Technology for Spaceflight ApplicationsWritten by Lori Keesey
In the most recent application of the carbon-nanotube coating, optical engineer John Hagopian, a contractor at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and Goddard scientist Lucy Lim are growing an array of miniscule, button-shaped bumps of multi-walled nanotubes on a silicon wafer. ![]() John Hagopian (left) collaborated with instrument scientist Lucy Lim to develop a new instrument that relies on carbon nanotubes to provide the electrons needed to excite minerals contained in an extraterrestrial sample. Larry Hess (right) patterns all the leads and patches where the catalyst for growing nanotubes is deposited.

NASA looks at studying Venus using CubeSatsWritten by Lori Keesey
A team of scientists and engineers working at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, has received funding from the agency’s Planetary Science Deep Space SmallSat Studies, or PSDS3, program to advance a CubeSat mission concept revealing the nature of this mysterious absorber situated within the planet’s uppermost cloud layer. ![]() As seen in the ultraviolet, Venus is striped by light and dark areas indicating that an unknown absorber is operating in the planet’s top cloud layer. The image was taken by NASA’s Pioneer-Venus Orbiter in 1979. (NASA) «Read the rest of this article» Sections: Technology | No Comments
NASA explores using Nanotechnology for Aerospace ApplicationsNASA Headquarters
Carbon nanotubes are small hollow tubes with diameters of 0.7 to 50 nanometers and lengths generally in the tens of microns. While ultra-small, carbon nanotubes offer big-time attributes. For instance, materials can be manufactured that exhibit superior strength but are still extremely lightweight. Think in terms of 200 times the strength and five times the elasticity of steel. For good measure, add in that they offer highly-efficient electrical and thermal conductivity. ![]() A carbon nanotube Composite Overwrap Pressure Vessel (COPV) is to fly this month as part of the SubTec-7 mission using a 56-foot tall Black Brant IX rocket launched from NASA’s Wallops Flight Facility in Virginia. Shown here is the SubTec7 payload undergoing final testing and evaluation at Wallops Flight Facility. (NASA/Berit Bland) «Read the rest of this article» Sections: Technology | No Comments
