SpaceX Dragon Grappled to Canadarm2

NASA – On Sunday, April 20, 2014, the Expedition 39 crew aboard the International Space Station welcomed nearly two-and-a-half tons of supplies and scientific payloads to the station with the arrival of the third SpaceX Dragon commercial cargo spacecraft. This image of SpaceX Dragon grappled by Canadarm2 was sent down by Flight Engineer Steve Swanson to Instagram with the message, “We have a Dragon. All is good.”

With Dragon securely in the grasp of Canadarm2, the robotics officer at Mission Control remotely operated the arm to install the capsule to its port on the Earth-facing side of the Harmony module. Once Dragon was in place, Flight Engineer Rick Mastracchio monitored the Common Berthing Mechanism operations for first and second stage capture of the cargo ship, assuring that the vehicle was securely attached to the station with a hard mate. Second stage capture was completed at 10:06 a.m. EDT as the station flew 260 miles above Brazil.

You Won’t Believe What This Machine Can See

GE – Two days before Christmas 1895, shortly after Wilhelm Röentgen discovered X-rays by experimenting with a cathode tube in his laboratory, he invited his wife to experience the phenomenon.

Anna Bertha Ludwig put her left hand inside his apparatus and became the first human to be X-rayed.

But when she saw her wedding ring slipped over the bones of her fourth finger, her reaction was far from jubilant. “I have seen my death,” she exclaimed.

Röentgen became immediately famous but it was not until 1913 that X-ray imaging took off.

That year physicist William D. Coolidge, a longtime director of the GE Research Laboratory in Schenectady, NY, invented the X-ray Tube.

Coolidge kept perfecting his tube and received 83 patents for the technology.

The tube effectively started radiology as a medical discipline and launched a series of innovations raging from the X-ray machine to computed tomography. more> http://tinyurl.com/las3err

Adopting Best Practices Can Be a Bad Idea

By Jackson Nickerson – Taking a best practice capability from one highly interconnected system and inserting it into another undoubtedly will lower performance, if the combined system works at all. Like Mary Shelly’s famous 1818 novel Frankenstein, combining modules from different systems can lead to a wretched capability.

When, then, does seeking out and copying a best practice capability make sense? more> http://tinyurl.com/n9n7m95

Fit to Print: New GE Plant Will Assemble World’s First Passenger Jet Engine With 3D Printed Fuel Nozzles, Next-Gen Materials

GE – GE Aviation will open a new assembly plant in Indiana to build the world’s first passenger jet engine with 3D printed fuel nozzles and next-generation materials, including heat-resistant ceramic matrix composites (CMCs) and breakthrough carbon fiber fan blades woven in all three dimensions at once.

Though the engine, called LEAP, will not enter service until 2016 on the Airbus A320neo,  it has already become GE Aviation’s bestselling engine, with more than 6,000 confirmed orders from 20 countries, valued at more than $78 billion. more> http://goo.gl/r8W1Om

Broadcasters Don’t Own the Airwaves

By Barry Diller – An “antenna in the cloud” records broadcast signals and sends them to users over the Web for viewing then or later on various devices. This has made an old analog technology relevant again, available to customers for only $8 a month. It’s not a piracy trick, as broadcasters have alleged, but a genuine innovation that consumers should be able to choose.

Yet broadcasters claim Aereo is “stealing” their content.

Why is the industry pushing to punish those who wish to receive their television through airwaves, which are not owned by broadcasters? more> http://goo.gl/YFLIkv
