The Parker Solar Probe was launched at oh-dark-early Sunday. From the article:

If all goes according to plan, the Parker Solar Probe will end up traveling faster than any craft ever has, and getting unprecedentedly close to the sun; indeed, it will fly through our star’s outer atmosphere, known as the corona. And the measurements the probe makes there will reveal key insights about our star’s inner workings that have eluded scientists for decades.

In addition to just being a cool bit of scientific and engineering awesomeness, this may provide some understanding of how the sun works. I’m also hoping it can help with models that can predict coronal mass ejections. Because although I do have preps, they’re mostly geared to “hurricane” not “years-long disruption of modern technology.”
