Check out NASA’s latest footage of a solar eclipse on Mars

Watching the most recent footage of a photo voltaic eclipse on Mars provides an entire new that means to the phrase “out of this world.”

Earlier this month, NASA’s Perseverance rover noticed one in all Mars’ moons, Phobos, passing throughout the Solar. The 40-second eclipse was captured by the rover’s Mastcam-Z digital camera system. It’s a partial photo voltaic eclipse due to the moon’s dimension. Whereas Phobos is the bigger of Mars’ two moons, it’s nonetheless extraordinarily small, measuring 17 x 14 x 11 miles in diameter. Its small dimension signifies that there can by no means be a complete eclipse on Mars. It doesn’t matter what, elements of the solar will at all times peek out from behind the shadows of Mars’ moons.

This isn’t the primary photo voltaic eclipse noticed from Mars. Different rovers have captured eclipses from the planet’s floor many occasions earlier than, together with this one from 2012, as seen by the Curiosity rover:

However this new footage is the “most zoomed-in video of a Phobos photo voltaic eclipse but – and on the highest-frame charge ever,” in response to NASA’s Jet Propulsion Laboratory (JPL). The Mastcam-Z digital camera is a serious improve to the cameras of earlier rovers. It’s a zoomable coloration digital camera and has a photo voltaic filter “that acts like sun shades to cut back mild depth,” in response to JPL. The end result? We are able to see Phobos’ craggy shadow passing throughout the Solar, together with some sunspots dotting our star’s orange floor.

“I knew it was going to be good, however I didn’t count on it to be this superb,” Malin House Science Techniques’ Rachel Howson, one of many individuals who operates the Mastcam-Z digital camera, stated in an announcement.

Along with simply being cool, the footage can be useful to scientists finding out Phobos’ orbit and its relationship to Mars. Because the moon orbits the planet, the 2 our bodies exert a gravitational pull on one another. Phobos tugs on Mars’ crust and inside, and Mars’ gravity pulls the moon towards the planet, altering its orbit. The truth is, Phobos has a fairly restricted lifespan. It’s getting pulled towards Mars at a charge of greater than 6 ft each century, and scientists suppose that the moon will finally be pulled aside within the subsequent tens of thousands and thousands of years. Luckily for us, that also leaves loads of time for rovers to seize beautiful movies just like the one launched this week.
