A spacecraft is beginning its 200 million mile journey back to Earth on Monday after taking samples from an asteroid.

This year’s only total solar eclipse will cross South American countries Chile and Argentina on Monday, Dec. 14. Watch live coverage of the eclipse beginning at 9:30 a.m. EST Monday in the video player below, courtesy of Slooh. A total solar eclipse occurs when the moon is the perfect size and distance from Earth to block out the sun entirely when their orbits cross paths. A total solar eclipse will cross Chile and Argentina on Dec. 14, 2020. Another total solar eclipse is expected to cross just below Detroit in 2024.

The only total solar eclipse of the year will cross South America on Monday, Dec. 14. A total solar eclipse will cross Chile and Argentina on Dec. 14, 2020. So, in those rare occurrences where the moon makes a direct path across the sun, we get a solar eclipse. Watch Slooh’s live coverage of the Dec. 14 total solar eclipse below. In 2024, a total solar eclipse will take a path quite close to Detroit.

A NASA spacecraft is preparing to land on an asteroid Tuesday to collect a sample. Spacecraft OSIRIS-REX is descending toward an asteroid named Bennu to suck up rubble as a sample for closer study back on Earth. OSIRIS-REX descended Tuesday toward the surface of the asteroid, which is 200 million miles away. The spacecraft dropped out of orbit around asteroid Bennu right on time, beginning a 4 1/2-hour plunge to the rough, boulder-covered face of the ancient space rock. Bennu’s gravity was too low for the spacecraft to land — the asteroid is just 1,670 feet (510 meters) across.
