The skies above the Eastern Shore of Virginia were filled with a massive fireball on Tuesday after an unmanned commercial rocket, which was supposed to bring fresh supplies to the people aboard the International Space Station, exploded just a few short seconds after it began it’s ascension.
According to The New York Times, the Antares rocket, developed by Orbital Sciences on a contract from NASA, was carrying over 5,000 pounds of fresh supplies, science experiments, and equipment when it lifted off from NASA’s Wallops Flight Facility in eastern Virginia, bound for the International Space Station.
Shortly after leaving the ground, however, the rocket burst into flames before exploding into countless pieces and falling back to the ground. Frank L. Culbertson Jr., the executive vice president of Virginia-based Orbital Sciences, said that “The ascent stopped. There was some disassembly of the first stage, it looked like, and then it fell to earth.”
“It is far too early to know the details of what happened,” Culbertson said in a statement, as quoted by NBC News, adding that the rocket and cargo alone were valued at around $200 million. “As we begin to gather information, our primary concern lies with the ongoing safety and security of those involved in our response and recovery operations.”

Alec Momont, a graduate student at the Delft University of Technology in the Netherlands, has created a prototype drone that will be able to autonomously navigate a location in just a few short minutes and deliver a defibrillator to people in need, according to PCWorld. The drone could prove life-saving in the event that someone collapses from cardiac arrest and there’s no defibrillator around to help reestablish normal heart rhythm.
“It is essential that the right medical care is provided within the first few minutes of a cardiac arrest,” Momont said, as quoted by CNET. ‘If we can get to an emergency scene faster, we can save many lives and facilitate the recovery of many patients. This especially applies to emergencies such as heart failure, drownings, traumas and respiratory problems, and it has become possible because life-saving technologies, such as a defibrillator, can now be designed small enough to be transported by a drone.”
“Some 800,000 people suffer a cardiac arrest in the EU every year, and only 8% survive,” Momont said, as quoted by Business Standard. “The main reason for this is the relatively long response time of the emergency services, while brain death and fatalities occur within 4 to 6 minutes. The costs should not be an issue; I have calculated these at approximately 15,000 euros per drone, which is clearly a reasonable amount if you consider the number of lives that could be saved.”

Researchers from the United States and the Netherlands have managed to transmit data across a kilometer-long, single strand of fiber cable at a whopping 255Tb/s, which is about 2,500 times faster than any commercial fiber. According to ExtremeTech, that’s close to 32TB per second, enough to transfer a 1GB movie in 0.03 milliseconds.
The researchers were able to achieve this using a so-called multi-core cable with 7 separate channels, although the hardware alone didn’t account for the insane speed. They also squeezed 50 carriers down the 7 cores, cranking each up to 5.1Tb/s using something that’s known as “spatial multiplexing.”
While none of that technology is new by itself, using them together is how the team was able to achieve a speed that’s so high, that the single strand of fiber that they used would be enough to handle the entire world’s peak internet traffic. Although you shouldn’t expect this technology to be implemented any time soon, as there’s no way to mass produce the cables. Still impressive.

Her jokes are getting funnier and her math is getting fuzzier. That seems to be the path that Hillary Clinton is traveling as she prepares for her 2016 presidential campaign with her latest sound bite from the pre-campaign trail.
“Don’t let anybody tell you it’s corporations and business that create jobs.” she said to a friendly audience supporting Martha Coakley’s gubernatorial campaign.
She then went on to attack the concept of trickle down economics. When neither statements drew applause of agreement, she resorted to a joke about her husband bringing arithmetic to Washington DC, which drew the intended laughs and changed the subject quickly.
There is no clear course for her campaign at this point. As the far left looks for someone more liberal and the right still attaches Benghazi and other failures to her name, she seems to be positioning herself to achieve something her husband had mastered before and during his terms. She’s trying to be likable.
Here’s the video:
