When the Great American Solar Eclipse sweeps across the continental U.S. on Aug. 21, astronauts aboard the International Space Station (ISS) will have a chance to see it from a unique vantage point.

"We're going to have a front-row seat to that [the solar eclipse] — 250 miles [400 kilometers] closer than you will there down on Earth," NASA astronaut Randy Bresnik told Space.com in a preflight interview on NASA TV.

Bresnik is scheduled to blast off toward the space station Friday (July 28) along with his two Expedition 52/53 crewmates, European Space Agency astronaut Paolo Nespoli and Russian cosmonaut Sergey Ryazanskiy. Liftoff is set for at 11:41 a.m. EDT (1541 GMT) The trio will spend six months aboard the orbiting lab.

Because the ISS orbits Earth every 92 minutes, the astronauts on board will have multiple chances to see the eclipse, which will last for a little over 4 hours. The eclipse will begin over the Pacific Ocean at 11:46 a.m. EDT (1546 GMT) and move southeast across the U.S., ending over the Atlantic Ocean shortly after 4 p.m. EDT (2000 GMT).

"Over three different passes, we'll get to see the solar eclipse looking up from the station on the first one," Bresnik said. "The next pass, when we come over the United States, we'll actually be able to see the solar eclipse as it transits across the continental U.S. And then, on the third pass … we'll actually be able to look up and see about an 85 percent occlusion of the sun."

In addition to seeing the moon's shadow on Earth, the ISS crew will get to view the eclipse directly by looking out the window toward the sun — with the proper eye protection, of course.

"We've got special filters and cameras, and we're ready to go take those pictures and go ahead and share them with you on the ground," Bresnik said.
