Israel Aerospace Industries, Hankuk Carbon, to make drones

Israel Aerospace Industries says it has formed a joint venture with Korean company Hankuk Carbon to make unmanned aircraft together. It says the new company, called Korea Aviation Technologies, will develop drones with vertical takeoff and landing capabilities. Its products will be aimed at both the military and civilian markets in South Korea. The two companies signed their joint venture agreement on Tuesday at the International Aerospace and Defense Exhibition in Seoul. Each will hold a 50 percent stake…

Drone hit Canadian airliner: minister

A view of Quebec City taken on July, 16 2017 A Canadian passenger plane landed safely after it was hit by a drone in the first case of its kind in the country, a cabinet minister said Sunday. With increasing numbers of unmanned aerial devices in the skies, collisions are still rare, but authorities around the world are looking at ways to keep jetliners out of harm’s way. The Canadian incident happened last Thursday when a drone collided with…

How scientists used NASA data to predict the corona of the Aug. 21 Total Solar Eclipse — ScienceDaily

When the total solar eclipse swept across the United States on Aug. 21, 2017, NASA satellites captured a diverse set of images from space. But days before the eclipse, some NASA satellites also enabled scientists to predict what the corona — the Sun’s outer atmosphere — would look like during the eclipse, from the ground. In addition to offering a case study to test our predictive abilities, the predictions also enabled some eclipse scientists to choose their study targets in…

NASA sounding rocket instrument spots signatures of long-sought small solar flares — ScienceDaily

Like most solar sounding rockets, the second flight of the FOXSI instrument — short for Focusing Optics X-ray Solar Imager — lasted 15 minutes, with just six minutes of data collection. But in that short time, the cutting-edge instrument found the best evidence to date of a phenomenon scientists have been seeking for years: signatures of tiny solar flares that could help explain the mysterious extreme heating of the Sun’s outer atmosphere. FOXSI detected a type of light called hard…

Asteroid tracking network observes close approach — ScienceDaily

On Oct. 12 EDT (Oct. 11 PDT), a small asteroid designated 2012 TC4 will safely pass by Earth at a distance of approximately 26,000 miles (42,000 kilometers). This is a little over one tenth the distance to the Moon and just above the orbital altitude of communications satellites. This encounter with TC4 is being used by asteroid trackers around the world to test their ability to operate as a coordinated international asteroid warning network. 2012 TC4 is estimated to be…

Changes in perspective may affect how useful drones really are

Credit: New Zealand Defence Force. Shared under a Creative Commons license. A recent study finds that users have trouble utilizing images from unmanned aerial systems (UASs), or drones, to find the position of objects on the ground. The finding highlights challenges facing the use of UAS technology for emergency operations and other applications, while offering guidance for future technology and training development. “Because UASs operate at heights that most normal aircraft do not, we are getting new aerial perspectives of…

Developing sensors to defend aircraft against lasers

Credit: Massachusetts Institute of Technology Laser strikes, the aiming of high-power laser pointers at aircraft, are a growing safety concern for pilots and aircraft passengers. They pose numerous dangers to pilots, including distraction during crucial moments in flight, temporary flash blindness, and in rare cases, permanent eye damage. Laser strikes have…

FAA bans drone flights near major US landmarks

The Federal Aviation Administration is banning drone flights within 400 feet (122 meters) of several national landmarks, including the Statue of Liberty and Mount Rushmore. The FAA announced the no-fly drone zones at 10 Department of the Interior sites on Thursday. They take effect Oct. 5. The restricted sites also include Boston National Historical Park, Philadelphia’s Independence National Historical Park and Jefferson National Expansion Memorial in St. Louis, Missouri. Five dams also are on the list: Nevada’s Hoover…

Solving the mystery of Pluto’s giant blades of ice — ScienceDaily

NASA’s New Horizons mission revolutionized our knowledge of Pluto when it flew past that distant world in July 2015. Among its many discoveries were images of strange formations resembling giant knife blades of ice, whose origin had remained a mystery. Now, scientists have turned up a fascinating explanation for this “bladed terrain”: the structures are made almost entirely of methane ice, and likely formed as a specific kind of erosion wore away their surfaces, leaving dramatic crests and sharp divides.…
