The future of smallsats: The smallest satellites of the world going to ready for the very next generation

The big news is the small satellite front of the world going to ready for the very next generation. From super secret agencies & the U.S. military to academia & private firms, as well as world space agencies & NASA, ultra small satellites are the big thing.

Cornell University has begun to delve into a postage stamp size satellite on a chip design, called Sprite, envisioning a swarm of these tiny probes exploring planetary atmospheres for organic compounds.

Call them a powerful force in the universe. Smallsats have already shown their ability to monitor disasters, study Earth's environment & support agriculture, cartography & earth science missions.

The future of smallsats, there will be growth, new missions, & new ways of working together, said Bille,expressing his own views & not speaking for Booz Allen Hamilton policy. CubeSats are like the personal computer of this industry.

Hunsaker's personal crystal ball predicts networked satellites with individual IP addresses controlled through the Internet & providing individualized positioning, communications, social & multimedia capability.Perhaps just like personal computing & cell phones that have common utility among individual consumers today, smallsats will also follow that trend, said colleague Tom Hunsaker, also an associate at Booz Allen Hamilton.

Bille concluded: The age of microspacecraft is on solid ground now. There's a definite trend toward putting small things together to do big accomplishments.

A New universal charging system for electric vehicles

The worldwide infrastructure of charging stations for electric vehicles[EV] may seem overwhelming, you know what would make it even more challenging? If each station had to separately cater to each make of EV on the road think of how many different styles of mobile phone chargers are currently out there, for instance, & then picture that applying to cars. Fortunately a consortium of automakers has developed the Combined Charging System that will allow any one vehicle to charge its batteries using a variety of different charging methods.

The system was developed by Germany's Audi, BMW, Daimler, Porsche, & Volkswagen, working in partnership with America's Ford & General Motors.

It consists of a single interface on the vehicle, which is compatible with methods such as one-phase AC-charging, fast three-phase AC/DC charging at home & ultra~fast DC charging at public stations. This is intended to make EV development a less complex process, as vehicles won't need to incorporate multiple inlets, nor will their drivers need to seek out specific charging stations. Instead, all electric vehicles will be able to recharge at all stations.

The technology also features a charging communication system, along with an electrical & safety architecture, that will work with any vehicle using the system.

The Combined Charging System is being demonstrated at the 15th International VDI Congress & Exhibition [Electronic Systems for Motor Vehicles], which takes place this Wednesday & Thursday in Baden~Baden. It should be ready for deployment in the auto industry by the middle of next year.

Ultrasound Help For Heal Broken Bones

Scottish doctors are using ultrasound to help speed the recovery of broken bones by stimulating bone regeneration through cell vibration. And the sound frequency & pulse rate of the ultrasound is different than that used on pregnant women, but the technology is the same. The transducer gets a coating of water based gel, & is then slipped into a strap that holds it on the break, stimulating cellular activity.

Doctors found that the ultrasound therapy can lower recovery time by more than one third.

A Florida School District is Taking Attendance by Scanning Students' Fingers

Roll call is going high-tech in Washington County, Fla. Rather than the usual name calling & response, students are now checking into class with finger scanning devices. & to keep better track of students from the minute they come under district supervision until they are delivered safely home again, the scanners are now moving from the school building to the school bus.

The systems have been active inside Washington County schools for roughly two months, but since most of the students in the district ride the bus anyhow, officials have decided the best place for the scanners is on the buses themselves. In the next week, a handful of buses will get the scanners. If the system proves worthwhile, all buses will have them by semester’s end.

At $30 per student per year, the system isn’t necessarily cheap. But considering the uptick in attendance (which means more money from the state in many districts) & the inherent increase in accountability & student safety, it may well be worth the cost. & naturally, parents who don’t want their children fingerprinted coming to & from school for whatever reason can opt to have their kids check in with their teachers in a more analog fashion.

Criminals target mobile devices & social networks !

Smartphones & social networking sites are likely to become the next big target for cyber criminals, according to a security industry report.

Symantec's annual threat analysis warns that the technologies are increasingly being used to spread malicious code.

Users of Facebook, Twitter & Google's mobile operating system, Android, are said to be particularly vulnerable.

However, the number of attacks remains small compared to other online crimes such as e-mail phishing.

According to Symantec, known vulnerabilities in mobile operating systems rose from 115 in 2009 to 163 in 2010.

In several cases, the security holes were exploited & used to install harmful software on Android handsets - suggesting that criminals now view smartphone hacking as a potentially lucrative area .

At least six different varieties of malware were discovered hidden in applications that were distributed through a Chinese download service.

"It is something we have started to see happen, albeit on a small level," said Orla Cox, security operations manager at Symantec.

"It allows people to do a variety of things from intercepting SMS messages to dialling toll numbers. They have opened up the possibility of what is there."

Several pieces of malware were also found on iPhones, however only devices that had been "jailbroken" to bypass Apple's security were affected.

The company's process of pre-vetting all new applications is believed to have spared its devices from a major attack.

Rogue applications

On Facebook & Twitter, Symantec's analysis highlighted several different types of threat.

Among the most prevalent were web links that encourage users to click through to other sites containing malware & rogue applications, designed to collect personal information.

The company estimates that one in six links posted on Facebook pages are connected to malicious software.

User information is said to be particularly valuable in "social engineering" attacks, where criminals use knowledge of an individual to trick them into scams that appear to relate to them personally.

Attack toolkits

Symantec makes its money selling internet security software & services to individuals & corporations

Its annual Internet Security Threat Report - based on data supplied by users around the world - is generally regarded as a reliable measure of changing trends in cyber crime.

Globally, the company recorded a 93% increase in the volume of web-based attacks between 2009 & 2010.

The dramatic rise was largely attributed to the widespread availability of "attack toolkits" - software packages that allow users with relatively little skill to design their own malicious software.

Toolkits are available to buy online for as little as a few pounds & as much as several thousand for the latest versions.

The most popular attack kit was Phoenix, which exploits vulnerabilities in the Java programming language - commonly used for web-based applications.

Symantec's report also notes a rise in the number of targeted attacks, where specific companies, organisations or individuals are singled out.

The most sensational targeted attack of 2010 was undoubtedly Stuxnet. The software worm was designed to take control of mechanical systems used in Iran's nuclear plants.

It has been widely speculated that the USA or Israel may have played a role in its creation.

Despite Stuxnet's headline-grabbing nature, Orla Cox believes that it may not be indicative of things to come.

"It was interesting to see that it is possible to attack physical systems. I think it unlikely that we will see a whole slew of attacks of that nature," she said.
