Perseverance rover watches eclipse of Mars' doomed 'potato' moon

NASA's Perseverance Mars rover captured this image of Phobos, one of Mars' two moons, during an eclipse.

(CNN)The Perseverance rover just witnessed a unique kind of eclipse while sitting on the surface of Mars -- and the robotic explorer captured video of it.

Perseverance observed the 40-second eclipse on April 2. If this sounds much shorter than a typical solar eclipse we might see from Earth when our moon passes in front of the sun, it's because Phobos is about 157 times smaller than our moon.
    The rover continues an 18-year history of robots watching eclipses on Mars that began with NASA's Spirit and Opportunity rovers in 2004 and was followed by Curiosity capturing the first video of a Martian eclipse in 2019.
      Perseverance has provided the best video of this eclipse yet using the zoom capabilities of its mast-mounted camera system.
      "I knew it was going to be good, but I didn't expect it to be this amazing," said Rachel Howson, Mastcam-Z camera operator at Malin Space Science Systems in San Diego, in a statement. "It feels like a birthday or holiday when they arrive. You know what's c
