American Airlines' Computer Glitch Leaves It Without Pilots Over Christmas

Traveling during the holidays is, by definition, no fun. If you caught a flight over Thanksgiving this year, you got lucky—everything ran more or less to plan. No freak winter storms, no striking baggage handlers, no collapsing computer systems. Expecting the Christmas travel rush to go just as …

Cable-laying drone wires up remote Welsh village

A drone has helped bring superfast broadband services to an isolated Welsh village. Cable company Openreach used the drone to avoid having to lay cable across "challenging" terrain that included woods, a river and steep hills. The drone was flown across a section of forest near Pontfadog, Wrexham...

Would You Go to School to Learn How to Mine in Space?

Hunter Williams used to be an English teacher. Then, three years into that job, he started reading the book The Moon Is a Harsh Mistress. The 1966 novel by Robert Heinlein takes place in the 2070s, on the moon, which, in this future, hosts a subterranean penal colony. Like all good sci-fi, the pl...

Crossing drones with satellites: ESA eyes high-altitude aerial platforms / Navigation / Our Activities / ESA








High Altitude Pseudo-Satellites, or HAPS, are platforms that float or fly at high altitude like conventional aircraft but operate more like satellites – except that rather than working from space they can remain in position inside the atmosphere for weeks or even months, offering continuous coverage of the territory below.

The best working altitude is about 20 km, above the clouds and jet streams, and 10 km above commercial airliners, where wind speeds are low enough for them to hold position for long periods.continue reading http://www.esa.int/Our_Activities/Navigation/Crossing_drones_with_satellites_ESA_eyes_high-altitude_aerial_platforms/(print)

Rocket Lab announces window for next Electron launch



PR





Rocket Lab will open a ten-day launch window from Friday December 8, 2017 NZDT to carry out the company’s second test launch of the Electron rocket. During this time a four-hour launch window will open daily from 2:30 p.m NZDT.

The test launch, titled ‘Still Testing’, will take place from Rocket Lab’s Launch Complex 1 on the Māhia Peninsula, New Zealand. It follows on from the successful inaugural Electron test carried out on May 25, 2017.

Still Testing will be the first Rocket Lab launch to be live streamed to the public. A live video stream will be available approximately 12 minutes prior to a launch attempt at www.rocketlabusa.com

The test launch attempt will only proceed if conditions are ideal for launch. Due to the nature of launching rockets, planned lift-offs are often subject to multiple and subsequent postponements, or scrubs, to allow for small, technical modifications and to wait for ideal weather conditions.

Peter Beck, Founder and CEO of Rocket Lab, says the test is an important next step in making space accessible and the team will be focusing on gathering more data to inform future launches.

“Electron’s first test made history when it became the first orbital-class launch vehicle to reach space from a private launch facility. We analysed more than 25,000 channels of data from flight one, and we’re eager to learn more from this test flight. This is the first test carrying customer payloads and we’ll be monitoring everything closely as we attempt to reach orbit,” he says.

“Once again, we’re expecting to scrub multiple times as we wait for perfect conditions and make sure everything on the vehicle is performing as it should.”

Still Testing will carry an Earth-imaging Dove satellite for Planet and two Lemur-2 satellites for Spire for weather and ship tracking, enabling Rocket Lab to gather crucial data and test systems for the deployment stage of a mission.

Still Testing is the second of three test launches planned from Launch Complex 1 ahead of commercial operations, however if the vehicle performs nominally throughout the second test the commercial phase may be accelerated.
