https://opensource.com/article/17/3/iot-security-raspberry-pi?sc_cid=7016000000127ECAAY The Raspberry Pi and many other inexpensive computer boards like it have become part of the “Internet of Things” or IoT revolution. Because your Raspberry Pi is a Linux system, most advice for security on larger systems applies to your project, too. Find out what sensible steps you can take to protect your Raspberry Pi →
https://www.space.com/38160-when-how-watch-cassini-saturn-dive.html Today (Sept. 15), NASA’s Cassini spacecraftwill dive into Saturn’s atmosphere and disintegrate. You can watch the action live right here on Space.com The $3.26 billion Cassini-Huygens mission — a joint effort of NASA, the European Space Agency and the Italian Space Agency — launched toward Saturn in 1997 and arrived at the system in 2004. “We’ll be →

Solar eclipse is nearing for people who live in USA. You can enjoy he view and even make scientific experiments (like verify yourself Was Einstein Right?). Whatever you do, be sure to know what to do to be safe. As August 21 solar eclipse in USA nears, remember that it’s extremely dangerous to look at the sun directly, even →

The U.S.-operated Global Positioning System (GPS) is only accurate to about 10 meters, while Europe’s corresponding Galileo system →
http://www.iflscience.com/physics/a-photon-has-been-sent-to-space-using-quantum-teleportation/ Last month, Chinese researchers showed that quantum communication between Earth and space is possible, and now they have used the tech to send a photon to space using quantum teleportation. As this research shows, to create a truly global network for quantum communication, we will need quantum satellites. →
http://www.aalto.fi/en/current/news/2017-06-30/ In a recent publication, Aalto University researchers show that in a transparent medium each photon is accompanied by an atomic mass density wave. The novel discovery solves the centennial momentum paradox of light. If this theoretical finding is proven true with experiments, it can affect our understanding of universe: “Presently the Hubble’s law is explained →
https://blog.hackster.io/launching-open-hardware-satellites-93813a1fe842 Created almost twenty years ago the CubeSat standard has lowered the barrier to entry to the point where you can put your own satellite into orbit for not much more than the price of a high end car. The 10 cm × 10 cm × 10 cm cubes have become so common that you can buy →
http://spectrum.ieee.org/tech-talk/aerospace/space-flight/scientists-figure-out-possible-new-threat-to-spacecraft Micrometeoroids don’t pack enough punch to get through a spacecraft’s hull. But according to new simulations reported this week in the journal Physics of Plasmas, they can generate a potentially crippling pulse of radio-frequency radiation. →
