While Mars is visible in the night sky nearly all year round, it can get extremely bright every few years.
But the eclipse that will stretch from South America to New Zealand on Friday will last nearly four hours, coming in at three hours and 55 minutes. A period of complete eclipse, known as "totality", will last from 3:30 p.m.to 5:13 p.m. ET.

You can see the live stream below: If you aren't aware, a lunar eclipse takes place when Earth comes in between the Sun and the Moon.
The probability of a simultaneous blood moon and total lunar eclipse is very low, reports say.

"This is actually nearly as long as a lunar eclipse could be", Prof Tim O'Brien, an astrophysicist at University of Manchester, explained.
Friday night's total lunar eclipse will be visible across Europe, Africa, the Middle East and in many parts of Asia and Australia. The Bible contains references to the moon turning into blood and some ultra-Orthodox Jews consider lunar eclipses ominous and a cause for moral contemplation.
The moon will be totally eclipsed for an estimated 1 hour and 43 minutes in the prime viewing region, according to NASA predictions.
While hoaxers have claimed that Mars will appear as the same size of the moon during the eclipse, the US-based National Aeronautics and Space Administration (NASA) dispelled the rumors.
Almost 2,000 curious skygazers converged at New Delhi's Nehru Planetarium to witness the century's longest lunar eclipse, but had to return disappointed as clouds completely surrounded the moon as if to hide it.
And yes, you'll likely hear this eclipse being referred to as the "blood moon".
"Part of South America will be able to watch the final stages of the eclipse just after sunset on July 27".
Aside political events, changes in weather patterns including events in the atmosphere like eclipses have also been seen as signs of the end times.
It depends partly on "how cloudy or transparent those parts of the Earth's atmosphere are which enable sunlight to reach the moon", he said. These two events so close to one another will make Mars brighter and much easier to view in the night sky. This light appears reddish.
