What are you up to at say... 2:30ish in the morning on Saturday? That's when the #ParkerSolarProbe's launch countdown begins for the NASA mission to "Touch the Sun." If you cannot get up that early (or stay up that late) check in with us later in the day for coverage. You can also tune into Facebook on Sunday for a Live Q&A with #UChicago graduate and #NASA mission principal investigator Kasper.Justin (NASA Live Stream Link in Bio)
