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

The U.S.-operated Global Positioning System (GPS) is only accurate to about 10 meters, while Europe’s corresponding Galileo system

A Photon Has Been Sent To Space Using Quantum Teleportation | IFLScience

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.

Transfer of atomic mass with a photon solves the momentum paradox of light – Aalto University

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

Launching Open Hardware Satellites – Hackster’s Blog

The 10 cm × 10 cm × 10 cm cubes have become so common that you can buy
