NASA ’s Perseverance roamer has captured the cleared ever footage of asolar eclipseover Mars , and the answer are out of this world .
The rover snapped the ethereal video ofMars’potato - shaped moon , Phobos , moving across the human face of thesunon April 2 . During the occultation , Phobos projected its uneven shadow over the Martian surface — appearing almost as though it was the pupil of a mammoth eyeball pealing in its socket .

Mars' moon Phobos crosses the face of the sun, captured by NASA’s Perseverance rover with its Mastcam-Z camera. The faint black specks to the bottom left are sunspots.
Perseverance put down the footage midway through its journeying to a river delta on Mars ’ 28 - mile - wide ( 45 kilometers ) Jezero Crater , where it will explore for grounds of life on the Red Planet . Training its state - of - the - prowess Mastcam - Z camera on the sky , the rover recorded the misshapen moon ’s solar transit with the neat rapid climb and at the highest framerate ever .

" I knew it was going to be good , but I did n’t expect it to be this amazing , " Rachel Howson , a mission surgery specialist at Malin Space Science Systems and one of the Mastcam - Z team members who operates the camera , said in a command .

Phobos , named after the Greek god of reverence , is around 157 times smaller thanEarth ’s moon and is one of Mars ' two born satellites , alongside the even smaller Deimos ( whose name comes from the Greek graven image of apprehensiveness ) .
Scientists consider that the brother moons were once roaming asteroids that were snared into Mars ’ orbit by the planet ’s gravitational field . The orbits of these wrapped asteroids are unstable , according to investigator , and scientists predict that in a few tens of million of year ' prison term Deimos will spin out into distance while Phobos will slam into Mars ’ surface .

investigator have been making eclipse watching of Phobos from the Martian control surface since 2004 , when the twinned NASA rovers Spirit and Opportunity snapped the first clip - oversight photos of the moonlight ’s passage . Similar observations were made by NASA ’s other activeMars rover , Curiosity , in 2019 . These earlier images were not very elaborated and were read in black-market and white , but Perserverance ’s improved Mastcam - Z enable scientists to take the first gloss images of the occultation . Mastcam - Z is also equip with a solar filter , which reduces the loudness of incoming light and enables scientist to entrance never - before - seen detail .

" you may see details in the shape of Phobos ’ shadow , like ridges and bulge on the moon ’s landscape , " Mark Lemmon , a planetary astronomer with the Space Science Institute in Boulder , Colorado , say in the statement . " you’re able to also see sunspots . And it ’s cool that you’re able to see this occultation exactly as the wanderer saw it from Mars . " sunspot have beenswarming the sun ’s surfacerecently following an step-up in solar activity , which havelaunched plasma wavesat Earth’smagnetic subject area .
NASA is n’t just eclipse - catch for the pretty images . make observations of Phobos ’ track around Mars is lively for meliorate scientific sympathy of the cursed moon ’s death volute . Studying occultation footage aid scientist observe the gravitational force-out between Mars and Phobos , and can supply information on the satellite ’s DoI and the tidal force shaping its impertinence and mantle . The same forces also roleplay on Phobos to subtly affect its electron orbit .
tenacity is a cardinal part of NASA ’s $ 2.7 billion Mars 2020 mission , which , alongside the Curiosity scouter , is searching for signs of ancientlife on Mars ’ open by garner dozens of rock samples for eventual replication to Earth over the next decade . The rover is accompany by the Ingenuity helicopter , which has so far made 25 flights over Mars .
