IN AUGUST 2017, scientists sailed a boat off South Carolina outfitted with a climate balloon. The plan was to float it above the clouds for a assured view of an impending whole solar eclipse. Then, a horrible storm struck. “They were mostly trying to keep the boat from capsizing,” says Angela Des Jardins, a physicist at Montana State University who leads the Nationwide Eclipse Ballooning Project.
The crew behind this mission had launched 55 balloons throughout the US in whole. As these popped and parachuted again to Earth, many bought caught in bushes. It took weeks to get them again. “This time,” says Des Jardins, “we’re giving everyone a special tree pole.”
After a six-year wait, the next whole solar eclipse over the US is nearly right here. First comes a apply run. On 14 October, an annular solar eclipse will see virtually all of the solar blocked by the moon, leaving simply a “ring of fire”. Then, on 8 April 2024, the actual deal arrives – a whole eclipse seen over a slender strip of North America.
The latter affords a chance to see a part of the solar normally hidden from view: its wispy, mysterious outer ambiance, referred to as the corona. This is the birthplace of the solar wind that travels by our patch of area, typically inflicting aurorae and disrupting satellites. But we understand little or no about it. The coming eclipses provide a unique, if fleeting, alternative to examine it. Over the previous few years, researchers have been…
