NASA has revealed a sneak peek at how we may be travelling in the year 2025.
Last year, the US space agency awarded contracts to three teams - Lockheed Martin, Northrop Grumman and Boeing - to study advanced concept designs for aircraft of the future. Their brief was a difficult one: to create aircraft that delivered less noise, cleaner exhaust and lower fuel consumption than today's planes, while still being able to achieve speeds up to 85 per cent of the speed of sound; cover a range of approximately 11,000 kilometres; and carry between 50,000 and 100,000 pounds (22,600 and 43,200 kilograms) of payload, either passengers or cargo. "Each aircraft has to be able to do all of those things at the same time, which requires a complex dance of tradeoffs between all of the new advanced technologies that will be on these vehicles," NASA said on its website.

On June 8, Google, Facebook, Yahoo and a host of other leading web companies will turn on a new way of running web addresses. The system, called IPv6, is designed to stop the world running out of the web addresses that underlie the locating of websites and devices. Currently, just 0.2 per cent of web users have access to the new protocol, however. 'World IPv6' Day is designed to encourage its adoption. Vint Cerf, one of the web’s founding fathers, is leading a global campaign to encourage web service providers and IT managers to switch from the current system, IPv4, to IPv6. The new standard offers many trillions of new web addresses, but cannot be accessed from modems and routers that only use IPv4. It is likely, however, that most of the changes needed will take place without consumers losing access to any part of the web because they will be part of the standard software and hardware upgrade cycle. Earth's Magnetic Field is constantly being bombarded by solar radiation by Zach Royer | Apparently Apparel ----------------------------------------------------------------------------------------------------------------------------------- (Overview of BGS) British Geological Survey - http://www.bgs.ac.uk/home.html Founded in 1835, the British Geological Survey (BGS) is the world's oldest national geological survey and the United Kingdom's premier centre for earth science information and expertise. The BGS provides expert services and impartial advice in all areas of geoscience. Our client base is drawn from the public and private sectors both in the UK and internationally. From the category "Earth Hazards" on the above website. The South Georgia observatory will plug a significant gap in the global network of magnetic observatories. In particular South Georgia observatory will allow better monitoring of the South Atlantic Anomaly and of changes occurring deep within the Earth. By establishing the new observatory, BGS will re-start continuous magnetic observations in South Georgia, last carried out in 1982. What is the South Atlantic Anomaly? The Earth’s magnetic field, generated deep within the planet, is a shield against particle radiation from space. In the South Atlantic this shield is much weaker than elsewhere across the globe and radiation from space therefore penetrates deeper into the atmosphere. This region is known as the South Atlantic Anomaly (SAA) and the radiation in the SAA is a known hazard to satellites, spacecraft and high-altitude aircraft. By Mike Wall This story originally appeared on Space.com When considering the prospect of alien life, humankind should prepare for the worst, according to a new study: Either we're alone, or any aliens out there are acquisitive and resource-hungry, just like us. These two unpalatable options are pretty much the only possibilities, according to the new study. That's because evolution is predictable, and alien biospheres should thus produce intelligent creatures much like us, with technological prowess and an ever-increasing need for resources. But the fact that we haven't run across E.T. yet argues strongly for the latter possibility -- that we are alone in the universe's howling void, the study suggests. "At present, as many have observed, it is very quiet out there," study author Simon Conway Morris, of the University of Cambridge, told SPACE.com in an e-mail interview. "And given many planetary systems are billions of years older than ours, I'd expect us to be best grilled on toast back in the Cambrian." STANFORD, Calif.--President Obama is planning to hand the U.S. Commerce Department authority over a forthcoming cybersecurity effort to create an Internet ID for Americans, a White House official said here today. It's "the absolute perfect spot in the U.S. government" to centralize efforts toward creating an "identity ecosystem" for the Internet, White House Cybersecurity Coordinator Howard Schmidt said. That news, first reported by CNET, effectively pushes the department to the forefront of the issue, beating out other potential candidates, including the National Security Agency and the Department of Homeland Security. The move also is likely to please privacy and civil-liberties groups that have raised concerns in the past over the dual roles of police and intelligence agencies. The announcement came at an event today at the Stanford Institute for Economic Policy Research, where U.S. Commerce Secretary Gary Locke and Schmidt spoke. |
