    Default Hubble Captures Phobos



    While imaging Mars, Hubble took 13 separate exposures over 22 minutes to create a time-lapse video showing the small moon's orbital path: https://www.nasa.gov/feature/goddard...the-red-planet.

    - A football-shaped object just 16.5 miles by 13.5 miles by 11 miles, Phobos is one of the smallest moons in the solar system
    - The little moon completes an orbit in just 7 hours and 39 minutes, which is faster than Mars rotates
    - Phobos was discovered by Asaph Hall on August 17, 1877 at the U.S. Naval Observatory in Washington, D.C., six days after he found the smaller, outer moon, named Deimos

    Quite the rarity. You don't hear much about Phobos in the news!

    While we're on the topic of Phobos, here is older NASA update you might not have seen: https://www.nasa.gov/feature/goddard...-falling-apart!

    - The long, shallow grooves lining the surface of Phobos are likely early signs of the structural failure that will ultimately destroy this moon of Mars
    - Orbiting 3,700 miles (6,000 kilometers) above the surface of Mars, Phobos is closer to its planet than any other moon in the solar system
    - New modeling supports the view that the grooves are more like “stretch marks” that occur when Phobos gets deformed by tidal forces
    - The tidal forces acting on Phobos can produce more than enough stress to fracture the surface

    Again very interesting. Looks like the groves have been there long before a lot of the impact craters. It almost looks like the moon was extruded, then peppered with meteors.
    Thanks again, Dave.

    Phobos does not even get love from Mars after all the planet essentially is eating away at Phobos and it will soon in cosmic time scales anyway be gone...

    For those interested, here is a pretty comprehensive 2016 article on Phobos: https://www.space.com/20346-phobos-moon.html. Some highlights:

    - In 1971, NASA's Mariner 9 spacecraft first orbited Mars; images revealed that both Phobos and Deimos have lumpy, potato-like shapes

    - The two moons are dark gray in color, and heavily cratered; some of the darkest, least reflective objects in the solar system

    - After observing the pair, scientists concluded that they were made of material similar to what makes up asteroids and dwarf planets

    - Within 50 million years, the moon will either collide with its parent planet or be torn into rubble and scattered as a ring around Mars

    - One of the competing concepts for NASA's next low-cost, Discovery-class mission selection would explore both Martian moons; this mission would launch in 2020 and arrive in 2021
