SEATTLE, July 12 (Reuters) - Jeff Bezos' rocket company plans to charge passengers about $200,000 to $300,000 for its first trips into space next year, two people familiar with its plans told Reuters.Potential customers and the aerospace industry have been eager to learn the cost of a ticket on Blue Origin's New Shepard space vehicle, to find out if it is affordable and whether the company can generate enough demand to make a profit on space tourism.Executives at the company, started by Amazon.com Inc founder Bezos in 2000, told a business conference last month they planned test flights with passengers on the New Shepard soon, and to start selling tickets next year.The company, based about 20 miles (32 km) south of Seattle, has made public the general design of the vehicle - comprising a launch rocket and detachable passenger capsule - but has been tight-lipped on production status and ticket prices.Blue Origin representatives did not respond to requests for comment on its programs and … [Read more...] about Sources reveal what Jeff Bezos plans to charge for space rides

In past negotiations aimed at reducing the arsenals of the world's nuclear superpowers, chiefly the U.S. and Russia, a major sticking point has been the verification process: How do you prove that real bombs and nuclear devices -- not just replicas -- have been destroyed, without revealing closely held secrets about the design of those weapons? Now, researchers at MIT have come up with a clever solution, which in effect serves as a physics-based version of the cryptographic keys used in computer encryption systems. In fact, they've come up with two entirely different versions of such a system, to show that there may be a variety of options to choose from if any one is found to have drawbacks. Their findings are reported in two papers, one in Nature Communications and the other in the Proceedings of the National Academy of Sciences, with MIT assistant professor of nuclear science and engineering Areg Danagoulian as senior author of both. Because of the difficulties in proving that … [Read more...] about For Nuclear Weapons Reduction, a Way to Verify Without Revealing
Tech & Science NASA A crash-test dummy’s life is full of ups and downs. That is perhaps even truer for the dummies NASA has enlisted. The space agency’s Langley Research Center in Virginia has given shed some light on the experiences of these abused figures, including footage of the devastating crashes they endure in the name of science. Researchers “have to use crash test dummies to evaluate the likelihood of injury when they’re either coming back to the ocean or they’re going to be coming back to land,” Martin Annett, a structural impact dynamics engineer, said in the NASA video. The “they” he refers to are astronauts returning from a space mission, but crash-test dummies are used to investigate more than just spacecraft—they could be used to make airplanes safer too, for example. The dummies are rigged up to deliver data from the crash’s impact to a computer, and the researchers analyze that data to find out if … [Read more...] about Watch: NASA Wrecks Crash-Test Dummies, Vehicles in the Name of Science
Sizing an IT infrastructure today can be tough. Although science is used to determine data center needs, there is still an art that goes into the decision process. The reason is simple. A variety of IT devices of various ages from various vendors — each with its own lifecycle, costs, and on-going maintenance issues — often present unforeseen consequences.Most IT equipment is expected to actively contribute for at least 3 years without any additional purchases, but it is difficult to anticipate things like IOPS and capacity one year in advance, much less 3 to 5 years ahead. And how do you plan for future technologies that haven’t been invented yet? Faced with so many variables, it’s surprising more IT professionals don’t consult Ouija boards before they make sizing decisions. All joking aside, sizing your infrastructure does include an element of fortune-telling, and some amount of risk is inherent in the process.Too small, too large, too many changesIf you … [Read more...] about The Art of Sizing Your IT Infrastructure
I sometimes like to tell a story about a computer science professor at my alma mater discussing the trade-offs of various data structures.It goes like this: A clever student tried to stump the professor. He asked: “What if I wanted a data structure that I wrote to but never read from?”The professor paused for a moment, and then responded: “In that case, I’d simply take the data and throw it away.”Put another way: If you’re never going to access the data, why store it in the first place? This friction is not hypothetical: Forrester Research estimates that somewhere between 60%and 73%of enterprise data is never used for analytics.While there are many contributing factors, security is a big one. In choosing between “data defense” (reducing risk) and “data offense” (driving revenue), businesses are forced to determine how much they are willing to limit access in the name of security. The sports adage that … [Read more...] about The Balance Between Going Fast and Being Safe: Can You Have Both?
