29 lis 2021 · Imaging data reveals a low albedo of both moons – Phobos: ∼0.07; Deimos: ∼0.08. Also, Phobos manifests distinct redder and bluer units, whereas the surface of Deimos is globally comparable to the Phobos redder units with localized streaks of brighter material.
15 paź 2018 · While both Phobos and Deimos warrant further scientific exploration, we conclude that Phobos is the most viable human exploration target because of its higher surface gravity, greater escape velocity, and more potential radiation shielding.
8 gru 2017 · Phobos and Deimos bear more resemblance to asteroids than to Earth's moon. Both are tiny — the larger, Phobos, is only 14 miles across (22 kilometers), while the smaller, Deimos, is only...

27 wrz 2011 · While prior mission concepts have tended to focus on Phobos, we conclude that Deimos is the better destination for an early teleoperation mission largely because it is farther from Mars than...
Summary: Phobos and Deimos, Mars’ two moons, are associated with significant planetary protection knowledge gaps for human missions, that may be filled by a low cost robotic reconnaissance mission focused on elucidating their origin and volatile content. Introduction: Phobos and Deimos are currently
