The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, CA and Denver, CO. The Thermal Emission Spectrometer is operated by Arizona State University and was built by Raytheon Santa Barbara Remote Sensing. MSSS operates the camera from its facilities in San Diego, CA. and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. Previous images from the Viking spacecraft in the 1970's were not of sufficient resolution to show the effectiveness of gravity on Phobos in moving material down slopes. The motion of debris down slopes is guided by gravity, which is only about 1/1000th that of the Earth - e.g., a 68-kilogram (150- pound) person would weigh only about 57 grams (2 ounces) on Phobos. The presence of material of different brightness on the far crater slopes and in some of the grooves shows that the satellite is heterogeneous (that is, it is made of a mixture of different types of materials). The far wall of the crater shows lighter and darker streaks going down the slopes (C). This crater is nearly half the size of Phobos and these grooves may be fractures caused by its formation. Also crossing at and near the rim of Stickney are shallow, elongated depressions called grooves. Some of these boulders are enormous - more than 50 meters (160 feet) across.
Individual boulders are visible on the near rim of the crater (D), and are presumed to be ejecta blocks from the impact that formed Stickney. This is the largest crater on Phobos, Stickney, 10 kilometers (6 miles) in diameter. The image shows several new features of this lumpy moon - features that are associated with the prominent crater seen in the upper left quarter of the image. This image is one of the highest resolution images (4 meters or 13 feet per picture element or pixel) ever obtained of the Martian satellite. Phobos was observed by both the Mars Orbiter Camera (MOC) and Thermal Emission Spectrometer (TES). The minimum distance between the spacecraft and Phobos was 1,080 kilometers (671 miles).

Elizabeth first got interested in space after watching the movie Apollo 13 in 1996, and still wants to be an astronaut someday.This image of Phobos, the inner and larger of the two moons of Mars, was taken by the Mars Global Surveyor on August 19, 1998. Elizabeth is also a post-secondary instructor in communications and science since 2015. in Space Studies from the University of North Dakota, a Bachelor of Journalism from Canada's Carleton University and a Bachelor of History from Canada's Athabasca University. Her latest book, "Why Am I Taller?", is co-written with astronaut Dave Williams. Elizabeth's reporting includes multiple exclusives with the White House and Office of the Vice-President of the United States, an exclusive conversation with aspiring space tourist (and NSYNC bassist) Lance Bass, speaking several times with the International Space Station, witnessing five human spaceflight launches on two continents, working inside a spacesuit, and participating in a simulated Mars mission. She was contributing writer for (opens in new tab) for 10 years before joining full-time, freelancing since 2012.

Solar eclipse guide 2022: When, where & how to see themĮlizabeth Howell (she/her), Ph.D., is a staff writer in the spaceflight channel since 2022 covering diversity, education and gaming as well. "As a result," they added, "geophysicists can use those changes to better understand how pliable the interior of Mars is, revealing more about the materials within the crust and mantle." These forces also slowly change Phobos' orbit," JPL officials said in the statement.
"As Phobos circles Mars, its gravity exerts small tidal forces on the Red Planet's interior, slightly deforming rock in the planet's crust and mantle. We're also learning more about the structure of Mars from such observations. Mars Express is currently the only spacecraft capable of close encounters with Phobos. The movie comprises 41 images taken on 17 November 2019, when Phobos passed Mars Express at a distance of 2400 km. Roughly 20 years of eclipse observations like this, taken from rovers on Mars, have refined the understanding of that moon's slowly collapsing orbit. A new image sequence from Mars Express now captures Phobos’ motions and surface in detail. Phobos is in a death spiral over Mars and will likely crash into the Red Planet's surface in a few tens of millions of years, researchers say. Scientists think the two lumpy bodies may be former asteroids that were captured by Mars' gravity. The other, Deimos, is even smaller than Phobos.
Phobos, which is about 157 times smaller than Earth's moon, is one of Mars' two natural satellites.
