NASA Uses Laser to Beam HD Video from International Space Station
NASA successfully beamed a high-definition video from the International Space Station to Earth last Thursday using a new laser communications instrument. The 175-megabit video transmission of “Hello, World!” was the first of its kind for the Optical Payload for Lasercomm Science (OPALS), a technology demonstration that allows NASA to test optical communications—also known as … [Read more...]
EMF Instrument to Fly Aboard Virgin Galactic Flight
Researchers from the Johns Hopkins University Applied Physics Laboratory (APL) have announced plans to install an electromagnetic field measurement instrument aboard Virgin Galactic’s SpaceShipTwo as part of the first NASA-funded science mission on a suborbital space plane. The instrument will analyze the electromagnetic fields inside the spacecraft during the 90-minute … [Read more...]
Medical-Grade Heat-Shrink Tubing for Cable Shielding
Methode Electronics, Inc. has released new medical grade shrinkMate™ heat-shrink tubing, which provides easy-to-apply shielding at the cable-to-connector joint, a common point of leakage. Made of clear medical grade polyester, the lightweight tubing shrinks when heat is applied to firm a conductive seal around an object, providing EMI, RFI and ESD shielding without the use of … [Read more...]
