GREENBELT, Md. (NASA PR) — For the first time, NASA’s Neil Gehrels Swift Observatory tracked water loss from an interstellar comet as it approached and rounded the Sun. The object, 2I/Borisov, traveled through the solar system in late 2019.

“Borisov doesn’t fit neatly into any class of solar system comets, but it also doesn’t stand out exceptionally from them,” said Zexi Xing, a graduate student at the University of Hong Kong and Auburn University in Alabama who led the research. “There are known comets that share at least one of its properties.”

This project aims to study the feasibility of integrating an array of microchips with space satellite functions, or ChipSats, on a multifunctional shape memory polymer (SMP) bus that is capable of self-folding when exposed to solar radiation.

This technology may enable the flat fabrication of kilometer-sized antenna arrays for radio astronomy that self-transform into the operative configuration once in orbit.

NASA Selects Early Stage Innovations from US Universities for Multi-Year Research, Development

WASHINGTON, DC (NASA PR) — Universities help propel NASA technology forward, researching everything from unique rocket engine designs to how landers interact with surfaces on other worlds. NASA has selected 14 university-led research proposals to study early-stage technologies relevant to these topics and more. The grants will fund ambitious projects to mature technologies for future NASA missions.

“There are talented researchers outside of NASA, working at universities across the country, who are poised to help us look at challenging aspects of space exploration in new ways,” said Walt Engelund, deputy associate administrator of programs within NASA’s Space Technology Mission Directorate in Washington. “With the help of these institutions and principal investigators, NASA will accelerate innovation for critical space technologies.”


NSF, CASIS Select 3 Combustion & Thermal Transport Experiments for ISS

KENNEDY SPACE CENTER, Fla., August 9, 2017 (CASIS PR) –  The Center for the Advancement of Science in Space (CASIS) and the National Science Foundation (NSF) today announced three projects have been selected from a joint solicitation focused on leveraging the International Space Station (ISS) U.S. National Laboratory in the fields of combustion and thermal transport. In total, up to $900,000 will be awarded for these three investigations to support flight projects to the ISS National Laboratory.

Through this partnership, CASIS and NASA will facilitate hardware implementation and on-orbit access to the ISS National Laboratory.  NSF will fund the selected projects to advance fundamental science and engineering knowledge. CASIS is the nonprofit organization responsible for managing and promoting research onboard the ISS National Laboratory. NSF supports transformative research to help drive the U.S. economy, enhance national security and maintain America’s position as a global leader in innovation.
