U.S. Army Puts a Stop to Its Use of Chinese-Made DJI Drones

No longer Army material: DJI’s Inspired 1 drone.
Security concerns lead to ban of a popular brand of UAV.

Citing a worry over “cyber vulnerabilities,” the U.S. Army this week ordered that all drones built by China-based DJI, the world’s largest drone manufacturer be forthwith removed from Army service. The order comes following a classified study of the issue completed in May by the Army Research Laboratory, and the simultaneous release of a Navy memorandum titled “Operational Risks with Regards to DJI Family of Products.”

According to aviation attorney Jonathan Rupprecht, the FAA has recently created more than 500 security-related flight restrictions prohibiting unpiloted aircraft flights over military locations...

Earth from Space: NASA 15 Amazing Things in 15 Years. Enjoy this journey.

NASA and other space agencies had launched satellites to study Earth before. But the past 15 years have produced a more comprehensive look at Earth from space than any other period in history. At a time when our planet is undergoing critically important changes, this global view offers not only stunning imagery but also vitally important information about how Earth is changing.

To celebrate 15 successful years of the Earth Observing System, we’ve collected 15 impressive, awe-inducing or simply just plain interesting images gathered by NASA’s three flagship Earth orbiters since the Terra launch.

Enjoy. And here’s to the next 15.

HERE IS WHAT THE SUN LOOKS LIKE UNDER THE NEW XRAY TELESCOPE FROM NASA

NuStar, NASA’s newest x-ray telescope, has returned its first startling image of the sun. image www.spy-drones.com

NuStar, NASA’s newest x-ray telescope, has returned its first startling image of the sun.

The telescope was built to spot black holes and other distant and dark stellar objects. This is the first time the spacecraft has trained its eyes on our own sun. It’s a kind of out-there idea hatched in the early days of the mission, when scientists realized NuStar’s powerful instruments might be able to see new details in our star. Because NuStar senses x-rays, they could turn it toward the sun without hurting the instruments.

NuStar already has given insights into temperature fluctuations above sunspots. It may also be able to capture theorized nanoflares in action...

NASA FUNDS LOCKHEED TO DESIGN A SUPERSONIC DRONE FOR THE AIR FORCE.

NASA awarded Lockheed Martin a modest $892,292 earlier this month to study the feasibility of developing an unmanned hypersonic spy plane called the SR-72. This superfast recon drone, first teased in November 2013, would fly at speeds of Mach 6.0, or 4,500 mph. That’s almost double the speed of the Lockheed SR-71 Blackbird, which made its first flight 50 years ago.

Neither Lockheed Martin Skunk Works nor NASA Glenn Research Center officials are talking about the recent award. But a Lockheed Martin website notes that the company has been working with Aerojet Rocketdyne to find a way to integrate a turbine engine, which would get the plane up to Mach 3, with a supersonic ramjet engine, or scramjet, to push it to Mach 6.

ooo

Scramjets are, structurally at least, pretty simple...

Laser Message from Space Says “Hello World”

On June 5th, 2014, the ISS passed over the Table Mountain Observatory in Wrightwood, CA, and beamed an HD video to researchers waiting below. Unlike normal data transmissions, which are encoded in radio waves, this one came to Earth on a beam of light. “It was incredible to see this magnificent beam of light arriving from our tiny payload on the space station,” says Matt Abrahamson, who manages the Optical Payload for Lasercomm Science at NASA’s Jet Propulsion Laboratory.

Better known as “OPALS,” the experimental laser device was launched to the space station onboard a Space-X Dragon spacecraft in the spring of 2014. Its goal is to explore the possibility of high-bandwidth space communications using light instead of radio waves...
