North America is on the verge of another masking of the sun.

Monday's total solar eclipse will make landfall along Mexico's Pacific coast and cross into Texas and 14 other U.S. states, before exiting over Canada.

It will last almost twice as long, with an even wider audience, than the total solar eclipse that stretched coast-to-coast in the U.S. in 2017.

The moon will shroud the sun for up to 4 minutes, 28 seconds, a spectacle normally unfolding in remote corners of the globe but this time passing over major cities like Dallas, Indianapolis and Cleveland.

NASA's VIPER—short for the Volatiles Investigating Polar Exploration Rover—now stands taller and more capable than ever, thanks to its mast.

VIPER's mast, and the suite of instruments affixed to it, looks a lot like the rover's "neck" and "head." The mast instruments are designed to help the team of rover drivers and real-time scientists send commands and receive data while the rover navigates around hazardous crater slopes, boulders, and places that risk communications blackouts. The team will use these instruments, along with four science payloads, to scout the lunar South Pole.

Don't be alarmed when the sky goes dark on April 8. A total solar eclipse will traverse North America, crossing Mexico, the United States, and Canada. This event will mark the only total solar eclipse visible from the United States until 2044. The full path of totality, as it's called, will begin on Mexico's Pacific Coast, cross northwestern Pennsylvania and New York state, and exit at the Atlantic Coast of Newfoundland, Canada.

A total solar eclipse occurs when the moon passes between the Earth and the sun, completely obscuring the sun from view. Those situated in the path of totality will see the moon fully cover the sun, the resulting shadow plunging the area into darkness during the day.

If the weather permits, spectators may also observe the "ring of fire," a term NASA uses to describe the stunning visual effect when the sun's outer atmosphere is visible as a luminous ring around the moon's silhouette against the darkened sky.

Here's what you need to know to experience this awe-inspiring event.

When is the next total solar eclipse?

The total solar eclipse will occur on April 8.

Japan's valiant moon lander was put to sleep again after unexpectedly surviving its second ultra-chilly long lunar night, the space agency said Monday.
