  • Oberg, Jamie (). „Russia's Dark Horse Plan to Get to Mars”. Discover. Arhivat din original la . Accesat în . The total delta-v required for a mission to land on Phobos and come back is startlingly low—only about 80 percent that of a round trip to the surface of Earth’s moon. (That is in part because of Phobos’s feeble gravity; a well-aimed pitch could launch a softball off its surface.)

  • „Stickney Crater-Phobos”. One of the most striking features of Phobos, aside from its irregular shape, is its giant crater Stickney. Because Phobos is only 28 by 20 kilometeri (17 by 12 mi), it must have been nearly shattered from the force of the impact that caused the giant crater. Grooves that extend across the surface from Stickney appear to be surface fractures caused by the impact.
