All communications from NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. to the Mars rovers and orbiters will be temporarily suspended during the next few weeks to prevent the sun from disrupting or damaging radio transmissions as it passes between Earth and Mars, NASA announced late last month. According to NASA, this phenomenon, known as a Mars solar conjunction, … [Read more...]
Giant Radio Telescope Prevents Use of Wi-Fi, Digital Textbooks, Online Standardized Testing at Nearby Public School
Students at a small public school in West Virginia are unable to use Wi-Fi because it could interfere with a giant radio telescope located nearby—a restriction that could spell trouble when the state completes its move to an online-only standardized aptitude test within the next two years. Located within the U.S. National Radio Quiet Zone and protected by the Appalachian … [Read more...]
PC-Based Universal PCB Test System Assists With Electronics “Fault-Finding” in Range of Industries
Saelig Co., Inc. has announced the availability of the System 8 Diagnostic Solution Plus PCB test system for electronics testing and “fault-finding” in a wide range of industries, including aircraft and transportation maintenance, PCB production houses and manufacturing. According to the company, the System 8 Diagnostic Solution Plus test system offers up to 64 digital and 24 … [Read more...]
FAA to Lift Electronics Flight Ban by End of Year, Sources Say
The Federal Aviation Administration (FAA) may soon lift the ban on the use of personal electronic devices (PEDs) during taxiing, take-off and landing and establish new rules on the use of tablets, laptop computers, e-readers and portable media players by the end of the year. The changes will not include cell phones. The New York Times reported Sunday that an FAA official and a … [Read more...]
EMP Blasts Emitted by “Space Dust” Determined as Cause for Satellite Failure
A Stanford researcher claims to have discovered the reasoning behind why some satellites inexplicably fail without extensive or visible damage. Although impacts with large space objects in space remain a potential cause, according to aeronautics and astronautics assistant professor Sigrid Close, the most likely cause of satellite failure is impacts from fast-moving … [Read more...]
Interference Affects NASA's Mona Lisa Transmission to the Moon
NASA has successfully transmitted a digital copy of Leonardo da Vinci’s Mona Lisa to the Lunar Reconnaissance Orbiter (LRO) via laser beam as part of an experiment designed to evaluate the possibility of replacing current radio systems with laser transmissions. Launched in June 2009, the robotic orbiter is currently in the process of creating a detailed, three-dimensional map … [Read more...]
Scientists Warn Earth Would Have 15 Minutes to Prepare for Solar Flare; Need to Develop Adequate Protection Now
As the sun continues to enter the peak of its 11-year cycle of magnetic activity, scientists around the world are becoming increasingly concerned about the possibility that a solar flare—a plasma cloud of charged particles—emitted by a solar superstorm could destroy global electronics networks with as little as a 15-minute warning. “Our message is, don’t panic, but do prepare … [Read more...]
U.S. Air Force Completes Testing of “Flying Wireless Router” Software Upgrade
The U.S. Air Force (USAF) has completed testing on a new software upgrade designed to provide airborne US military aircraft with wireless router capabilities, enabling “almost instantaneous” communication between groups of ground forces. According to the USAF, the Net-T software upgrade will be included in the LITENING and Sniper advanced targeting systems. The Net-T … [Read more...]
Sun Enters Peak of Magnetic Activity Cycle; Scientists Theorize Solar Eruptions Could Endanger Power Grids
Earlier this month, the National Weather Service’s Space Weather Prediction Center reported that a “type IV radio emission”—a major solar eruption of charged particles known as a coronal mass ejection (CME)—was approaching the earth. CMEs are capable of disrupting Earth’s magnetic field and triggering a geomagnetic storm that could potentially damage communications satellites, … [Read more...]
Quantum Imaging Experiment May Lead to “Unjammable” Aircraft Radar Detection System
Researchers at the University of Rochester in New York have utilized a technique based on the quantum properties of photons to develop the possible first “unjammable” aircraft radar detection system. Traditionally, anti-detection methods include drowning radar signals out with noise or launching false signals. Menhul Malik and his colleagues have developed a system capable of … [Read more...]
