A total eclipse occurs when Earth passes directly between the moon and the sun, and casts a shadow on our constant, cosmic companion. The moon will be 225,000 miles (362,000 kilometers) away at the peak of the eclipse — around midnight on the U.S. East Coast.
“This is this gradual, slow, wonderful event that as long as it’s clear where you are, you get to see it,” Petro said.
If not, NASA will provide a livestream of the eclipse from various locations; so will the Slooh network of observatories.
There’ll be another lengthy total lunar eclipse in November, with Africa and Europe lucking out again, but not the Americas. Then the next one isn’t until 2025.
Launched last fall, NASA’s asteroid-seeking Lucy spacecraft will photograph this weekend's event from 64 million miles (103 million kilometers) away, as ground controllers continue their effort to fix a loose solar panel.
NASA astronaut Jessica Watkins, a geologist, plans to set her alarm clock early aboard the International Space Station.
“Hopefully, we can be up in time and be at the right place at the right time to catch a good glimpse,” she told The Associated Press earlier this week.
