"NASA and some other companies are going to be launching some weather balloons during the eclipse. They'll go extremely high, about 70,000 feet and then they'll start to descend during the eclipse collecting data, taking pictures," KSP trooper Sean Wint said. "They do have blinking lights on them so we don't want people to freak out thinking something's coming down to visit us. It's actually just going to be the weather balloons."
