Peggy Whitson, Space Scientist

When astronaut Dr. Peggy Whitson returned from space earlier this year, it was a triumphant conclusion to a lifelong career as a scientist, explorer, and leader. Whitson is a biochemist who became one of the most experienced and distinguished astronauts ever to serve. She’s got more time logged in space than any other American. There’s a reason that she’s been called the Space Ninja.

Education and Early Life

Some people find their vocation late in life, but Peggy Whitson figured it out in her senior year of high school. It was 1979 and NASA had just accepted its first class …read more http://pje.fyi/PzmcbQ

Humans May Have Accidentally Created a Radiation Shield Around Earth

NASA spends a lot of time researching the Earth and its surrounding space environment. One particular feature of interest are the Van Allen belts, so much so that NASA built special probes to study them! They’ve now discovered a protective bubble they believe has been generated by human transmissions in the VLF range.

VLF transmissions cover the 3-30 kHz range, and thus bandwidth is highly limited. VLF hardware is primarily used to communicate with submarines, often to remind them that, yes, everything is still fine and there’s no need to launch the nukes yet.  It’s also used for navigation …read more http://pje.fyi/PCnk2p
