NASA Is Sending Humanity's First Spacecraft to the Sun in 2018

NASA announces the details of its mission to the sun, set to launch in 2018.


NASA announced the details of an “unprecedented” mission, which launches in 2018. Its spacecraft, in humanity’s first visit to a star, will get the closest we ever got to the sun. 

The probe, designed to survive at extreme temperatures and radiation levels, is named after living astrophysicist Eugene Parker, whose work contributed significantly to our knowledge of the sun, developing the theory of solar wind. NASA sees the probe as not only “historic” but promising to “revolutionize our understanding of the sun.” It will get within 3.9 million miles to the sun’s surface, more than seven times closer than our previous spacecraft. The hope is that it will help us prevent damaging space weather events, like solar storms.

The Parker probe will zip along at the speed of up to 430,000 miles per hour, covering 90 million miles and eventually traveling through the sun’s atmosphere into its corona. It will be built to withstand heat of 2,500 degrees Fahrenheit, providing us with invaluable information about the sun’s workings. The materials used in the probe simply didn’t exist before, according to the scientists.

“Parker Solar Probe is going to answer questions about solar physics that we’ve puzzled over for more than six decades,” said the project scientist Nicola Fox of Johns Hopkins University. “It’s a spacecraft loaded with technological breakthroughs that will solve many of the largest mysteries about our star, including finding out why the sun’s corona is so much hotter than its surface.”

The Parker Solar Probe is currently set to launch in a 20-day window opening on July 31, 2018.

Five foods that increase your psychological well-being

These five main food groups are important for your brain's health and likely to boost the production of feel-good chemicals.

Mind & Brain

We all know eating “healthy” food is good for our physical health and can decrease our risk of developing diabetes, cancer, obesity and heart disease. What is not as well known is that eating healthy food is also good for our mental health and can decrease our risk of depression and anxiety.

Politics & Current Affairs

For those of us who follow politics, we’re used to commentators referring to the President’s low approval rating as a surprise given the U.S.'s “booming” economy. This seeming disconnect, however, should really prompt us to reconsider the measurements by which we assess the health of an economy. With a robust U.S. stock market and GDP and low unemployment figures, it’s easy to see why some think all is well. But looking at real U.S. wages, which have remained stagnant—and have, thus, in effect gone down given rising costs from inflation—a very different picture emerges. For the 1%, the economy is booming. For the rest of us, it’s hard to even know where we stand. A recent study by Porch (a home-improvement company) of blue-collar vs. white-collar workers shows how traditional categories are becoming less distinct—the study references "new-collar" workers, who require technical certifications but not college degrees. And a set of recent infographics from CreditLoan capturing the thoughts of America’s middle class as defined by the Pew Research Center shows how confused we are.
