Last March (March 2019), the NASA Mars Curiosity rover camera captured the solar eclipse of every month on the planet, Phobos and Deimos.
The Curiosity Mastcam camera, which has solar filters that allow it to look directly into the sun, was recorded by Fobos on the morning of March 26, 2019 and Deimos on March 17, 2019.
The eclipse on Mars is not as complete as those we sometimes see here on Earth, during which the moon is completely darkening the sun. Two months of Mars are small, Phobos is 11.5 km away, and Deimos is only about 1/2 mile (2.3 km). As you can see in two animations, neither the Mars completely covers the sun.
With the recording of each month before the sun, one of the Curiosity cameras followed the shadow of Fobos on March 25, 2019. As the shadow of the Moon crossed the rover during sunset, the light shook for a moment. NASA said:
The picture was taken after the sun fell behind the horizon, just as Fobos lifted and threw an elongated shadow across the Mars area. Atmospheric dust particles acted as a screen against which a shadow was projected.
The solar eclipse has been seen many times by curiosity – which landed on Mars 2012 – and other roveries in the past. Besides being cool, these events also help researchers to precisely determine their understanding of the orbit every month around Mars.
Before the rope Spirit and Opportunity landed in 2004, there was much greater uncertainty in the orbits of each month, said Mark Lemmon from Texas A & M University, a co-researcher with Curiosity's Mastcam. The first time one of the rover tried to imagine Deimos blinding the sun, they found that the Moon was 40 miles away from where they were expecting. Lemmon said in a statement:
More observations over time help to determine the details of each orbit. These orbits are constantly changing in response to the gravitational attraction of Mars, Jupiter or even of every Mars that pulls on the other side.
So far, Mars roveri – or the Spirit, Opportunity or Curiosity – have made eight observations of Deimos that dazzle the sun from about 40 Fobos.
Conclusion: Mars Curiosity rocket camera captured solar eclipse with two months of Phobos and Deimos planets.
