WinSenga expands access to prenatal care in Africa with smartphone-based ultrasound alternative
Wubwub. Wubwub. Wubwub.
It’s immense, the moment an ultrasound lets an expectant mother hear her unborn child’s heartbeat. But many pregnant women around the world never get to experience it. (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.
