Lithium-oxygen breakthrough clears the air for boosted batteries [feedly]

Boasting an energy density similar to that of gasoline, lithium-air (or lithium-oxygen) batteries may one day prove the panacea for the range-anxiety associated with electric vehicles. But first there are a number of challenges that need to be overcome, one of which is the unwanted buildup of lithium peroxide on the electrode which hampers this type of battery's performance. Scientists have now figured out a way that this mess might be avoided – an advance they say could lead to batteries with five times the energy density of those currently available.

Eye tracking monitors helicopter pilots flying blind [feedly]

From battle zones to oil rigs, helicopters often operate in some of the hairiest situations in which pilots are forced to rely solely on cockpit instruments. In an effort to improve safety, the non-profit helicopter safety organization HeliOffshore is using eye-tracking technology to gain a greater understanding of how pilots operate in such scenarios.

Airbus Defence and Space and OneWeb create OneWeb Satellites company – the next stage of the OneWeb adventure

January 26, 2016 - Press release

- OneWeb Satellites is a joint venture equally owned by Airbus Defence and Space and OneWeb
- Company to design and build 900 satellites for OneWeb, as well as satellites for other future constellations marketed by Airbus Defence and Space

Airbus Defence and Space, the world’s second largest space company, and OneWeb, which is building a new global satellite communications system, announced the creation of OneWeb Satellites. The new joint venture, equally owned by Airbus Defence and Space and OneWeb, will design and build the 900 satellites of the OneWeb constellation, which will offer high-speed internet with global coverage. The new company will be led by Brian Holz as CEO.

OneWeb Satellites will also be able to build satellites, platforms and equipment to be marketed by Airbus Defence and Space to other operators of future constellations.

“The next stage of the OneWeb adventure is here! On both sides of the Atlantic, our teams are now working under a common flag to meet the incredible challenge: to mass-produce 900 satellites for the OneWeb constellation,” said Eric Béranger, Head of Programmes Space Systems. “For several months now, we have been working on the design of this unprecedented constellation and how we are going to manufacture them – both ground-breaking in their own way. The next step will be to set up a prototype line in Toulouse for production of the first 10 satellites. This will also be used to test the industrialisation method for the series production of the other satellites.”

"Airbus is a key partner to our success as we move forward and are very happy to have them being a part of OneWeb and our new joint venture. We are benefiting from Airbus Defence and Space’s manufacturing and assembly knowledge as we look to initiate services,” said Matt O’Connell, CEO of OneWeb. “As we build out the constellation, besides its very reliable satellite performance heritage and technical support, Airbus brings design for manufacturing capability into this operation which is key to achieving both our short term and long term goals for providing cost effective solutions on time for our future customers,” O’Connell added.

OneWeb Satellites will undertake design activities for the entire satellite fleet and the manufacture of the first 10 flight models will take place in France, with the first ever mass production of the operational satellites planned for North America. Each satellite will weigh less than 150 kg and will operate in low Earth orbit. They will be launched by Arianespace and Virgin Galactic starting from 2018 and reach their orbital positions using electrical propulsion.
