Powered by IBM Watson technologies, the artificial intelligence-powered astronaut assistant successfully completed the next step in its research on the effects of stress and isolation during long-term missions. (more…)
Thinking small has enabled an international team of scientists to gain new insight into the evolution of planetary building blocks in the early solar system.
The researchers compared the results of small-scale numerical simulations of colliding rock and dust particles to the composition of meteorites. They found that collisions helped transform initially porous materials into the more highly solidified asteroids and meteorites observed today. The team of seven scientists published their evidence last month in Nature Communications. (more…)
A team of about 20 working at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., through the lab’s Phaeton early-career-hire program, led the development of the Optical Payload for Lasercomm Science (OPALS) investigation, which is preparing for an April 14 launch to the International Space Station aboard the SpaceX-3 mission. The goal? NASA’s first optical communication experiment on the orbital laboratory.
Scientific instruments used in space missions increasingly require higher communication rates to transmit gathered data back to Earth or to support high-data-rate applications, like high-definition video streams. Optical communications-also referred to as “lasercom”-is an emerging technology where data is sent via laser beams. This offers the promise of much higher data rates than what is achievable with current radio frequency (RF) transmissions and has the advantage that it operates in a frequency band that is currently unregulated by the Federal Communications Commission.

Built with spare parts and without a moment to spare, the International Space Station (ISS)-RapidScat isn’t your average NASA Earth science mission.
Short for Rapid Scatterometer, ISS-RapidScat will monitor ocean winds from the vantage point of the space station . It will join a handful of other satellite scatterometer missions that make essential measurements used to support weather and marine forecasting, including the tracking of storms and hurricanes. It will also help improve our understanding of how interactions between Earth’s ocean and atmosphere influence our climate. (more…)
An astronaut orbiting Earth in the International Space Station has remotely directed a NASA rover in California to unfurl an “antenna film” that scientists at the University of Colorado Boulder are developing for use on the unexplored far side of the moon.
When astronaut Chris Cassidy used a Space Station computer to pilot the robot across a mock lunar surface at NASA’s Ames Research Center on June 17, he demonstrated for the first time that an astronaut in an orbiting spacecraft could successfully control a robot in real time on a planetary surface. The technique could have future applications for humans visiting Mars, an asteroid or the moon. (more…)
Space Station Commander Kevin Ford exchanged Valentine’s Day greetings with his adult kids Heidi and Anthony — he speeding by about 220 miles above Providence and they watching him fly past from Brown’s Ladd Observatory.
PROVIDENCE, R.I. [Brown University] — Rhode Islanders with their eyes skyward around 6 p.m. last Thursday might have noticed a curiously bright speck speeding across the evening sky. No, it wasn’t a UFO or an asteroid. It was the International Space Station, and for Providence resident Heidi Ford, it was dad’s office.
Heidi’s father Kevin Ford is currently the commander of the ISS. And with the help of Brown’s Ladd Observatory and astronomer Robert Horton, Heidi and her brother Anthony, who was visiting from Houston, got to see last week’s flyby close up while they talked to their dad on the phone. (more…)
PASADENA, Calif. – In a clever reuse of hardware originally built to test parts of NASA’s QuikScat satellite, the agency will launch the ISS-RapidScat instrument to the International Space Station in 2014 to measure ocean surface wind speed and direction.
The ISS-RapidScat instrument will help improve weather forecasts, including hurricane monitoring, and understanding of how ocean-atmosphere interactions influence Earth’s climate. (more…)
UD professor reports smart fluids research in scientific journal
Imagine a computer chip that can assemble itself.
According to Eric M. Furst, professor of chemical and biomolecular engineering at the University of Delaware, engineers and scientists are closer to making this and other scalable forms of nanotechnology a reality as a result of new milestones in using nanoparticles as building blocks in functional materials.
Furst and his postdoctoral researchers, James Swan and Paula Vasquez, along with colleagues at NASA, the European Space Agency, Zin Technologies and Lehigh University, reported the finding Sept. 17 in an article in the Proceedings of the National Academies of Science (PNAS) online edition. (more…)
