China to launch first e-commerce satellite in 2017
Posted by Karen Hurst in categories: economics, food, satellites
China plans to launch its first e-commerce satellite in 2017, with the primary purpose of using satellite data in agriculture.
The plan was announced on Monday during an international aviation and aerospace forum in Zhuhai, Guangdong Province, by the China Academy of Launch Vehicle Technology, China Aerospace Museum and Juhuasuan, an arm of e-commerce giant Alibaba.
“In an era of space economy, the potential of a commercial space industry is immeasurable,” Han Qingping, president of the Chinarocket Co., Ltd, said at the forum.

EU Commission’s new space policy to invest in startups to boost private investment
Posted by Andreas Matt in categories: policy, satellites, space
PARIS — The European Union’s executive commission on Oct. 26 unveiled a new space strategy that promises public investment to stimulate the creation of space start-up companies.
The Brussels, Belgium-based commission, which acts on behalf of the 28 European Union members — still including Britain for a couple of years — is already the biggest single customer for Europe’s Arianespace launch-service provider and for Europe’s satellite manufacturers.
The EU plans to launch some 30 satellites in the coming decade for the Galileo navigation and Copernicus environment-monitoring programs, which are the major beneficiaries of the commission’s space budget of 12 billion euros ($13.5 billion) between 2014 and 2020.

CubeSats could soon be zooming around space under their own power
Posted by Klaus Baldauf in categories: energy, satellites
Rubik’s-cube-sized CubeSats are a nifty, cheap way for scientists to put a research vessel into space, but they’re limited to orbiting where they’re launched – until now. Los Alamos researchers have created and tested a safe and innovative rocket motor concept that could soon see CubeSats zooming around space and even steering themselves back to Earth when they’re finished their mission.
Consisting of modules measuring 10 × 10 × 11.35 cm (3.9 × 3.9 × 4.5 in), these mini-satellites first launched in 2003, but are currently lacking in propulsion because they’re designed to hitch a ride into space with larger, more expensive space missions. They’re usually deployed along with routine pressurized cargo launches, usually into low orbits that limit the kinds of studies that CubeSats can perform.

No satellites needed for next-gen navigation system that uses “signals of opportunity”
Posted by Shane Hinshaw in categories: encryption, internet, military, mobile phones, robotics/AI, satellites
The Global Positioning System (GPS) is a great navigation aid – unless you lose the signal while negotiating a complicated spaghetti junction. That’s bad enough for conventional cars, but for autonomous vehicles it could be catastrophic, so the University of California, Riverside’s Autonomous Systems Perception, Intelligence, and Navigation (ASPIN) Laboratory under Zak Kassas is developing an alternative navigation system that uses secondary radio signals, such as from cell phone systems and Wi-Fi to either complement existing GPS-based systems or as a standalone alternative that is claimed to be highly reliable, consistent, and tamper-proof.
Today, there are two global satellite navigation systems in operation, the US GPS and the Russian GLONASS, with the European Galileo system set to become fully operational in the next few years, and plans for the Chinese Beidou system to extend globally by 2020. These have revolutionized navigation, surveying, and a dozen other fields, but GPS and related systems still leave much to be desired. By their nature, GPS signals are weak and positions need to be confirmed by several satellites, so built up areas or mountainous areas can make the system useless. In addition, GPS signals can be deliberately or accidentally jammed or spoofed due to insufficient encryption and other protections.

Rocket Lab Aims to Win Cubesat-Launching Race
Posted by Klaus Baldauf in categories: business, satellites
Rocket Lab is dedicating itself to launching small satellites cheaply and efficiently — a capability the American company thinks the burgeoning private spaceflight industry desperately needs.
Small satellites, some no bigger than a lunch box, are revolutionizing how people gather data about the Earth, and they might be the future of global communications.
Rocket Lab’s business model is a bit like Henry Ford’s was when he started selling Model T’s: keep the machine simple, produce a lot of them and keep them affordable. Peter Beck, the company’s owner, told Space.com that he’d like to reach a point where Rocket Lab launches one of its custom-made, small-satellite rockets about once per week. And similar to Henry Ford (who didn’t even want to make different colors of the Model T), Beck said that until that basic goal is met, he has no plans to diversify the company’s services.

Orbital ATK and Stratolaunch Systems Partner to Offer Competitive Space Launch Opportunities
Posted by Klaus Baldauf in categories: business, satellites
DULLES, Va.—(BUSINESS WIRE)— Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense technologies, and Stratolaunch Systems today announced a multi-year production-based partnership that will offer significant cost advantages to air-launch customers. Stratolaunch Systems, in cooperation with Vulcan Aerospace, is responsible for realizing Paul G. Allen’s vision for space.
“The combination of our extensive air-launch experience and the Stratolaunch aircraft has the potential to provide innovative and cost-effective options for commercial launch customers.” Tweet this
Under this partnership, Orbital ATK will initially provide multiple Pegasus XL air-launch vehicles for use with the Stratolaunch aircraft to provide customers with unparalleled flexibility to launch small satellites weighing up to 1,000 pounds into low Earth orbit. Pegasus has carried out 42 space launch missions, successfully placing more than 80 satellites into orbit for scientific, commercial, defense and international customers.

World War 3 Warning: Space War ‘Challenge’ Looming With China And Russia, U.S. Strategic Command General States
Posted by Karen Hurst in categories: existential risks, government, military, robotics/AI, satellites
A top U.S. general has issued a sobering warning that both China and Russia, given their years of emphasis on upgrading and renovating their space war arsenals, could, in the future, place the United States in a position of weakness if matters were to degenerate into a state of war between the countries. Air Force Gen. John E. Hyten believes that China and Russia have been attempting to outpace the U.S. in military matters with regard to space and that the Pentagon is now moving to counter the foreseen “challenge” of possibly being outmaneuvered and outgunned in space. If a World War 3 scenario were to actualize, he thinks the U.S. should be prepared to meet said challenge.
The Washington Times reported last week that Air Force Gen. John E. Hyten, who has been chosen as the next commander of Strategic Command, told Congress’ Senate Armed Services Committee that the U.S. is moving to counter the threat of a space war disadvantage with China and Russia. He said China and Russia are currently in the process of developing anti-satellite missiles, laser guns, and maneuvering killer space robots that could, once deployed, knock out or incapacitate strategic U.S. communications, navigation and intelligence satellites. As military experts know, these craft are crucial to the maintenance and actionability of America’s high-technology warfare systems.
“The Department of Defense has aggressively moved out to develop responses to the threats that we see coming from China and Russia. I believe it’s essential that we go faster in our responses.”
