Challenges in forming Phobos and Deimos directly from a splitting of an ancestral single moon [PDF]
arXiv, 2022 The origin and evolution of Martian moons have been intensively debated in recent years. It is proposed that Phobos and Deimos may originate directly from a splitting of an ancestral moon orbiting at around the Martian synchronous orbit. At this hypothetical splitting, the apocenter of the inner moon (presumed as Phobos) and the pericenter of the outer

The breakup of Martian boulders
Physics Today, 2013 The rate at which boulders have disintegrated on the surface of Mars can be estimated thanks to an unusual geomorphological formation. The rate at which boulders have disintegrated on the surface of Mars can be estimated thanks to an unusual geomorphological formation.

Perchlorate and Agriculture on Mars
Soil Systems, 2021 Perchlorate (ClO4−) is globally enriched in Martian regolith at levels commonly toxic to plants. Consequently, perchlorate in Martian regolith presents an obstacle to developing agriculture on Mars.

Physically Based Real‐Time Rendering of Eclipses
Computer Graphics Forum, EarlyView.Abstract We present a novel approach for simulating eclipses, incorporating effects of light scattering and refraction in the occluder's atmosphere. Our approach not only simulates the eclipse shadow, but also allows for watching the Sun being eclipsed by the occluder.

What Is the Radiation Impact of Extreme Solar Energetic Particle Events on Mars?
Space Weather, 2023 Solar Energetic Particles (SEP) are one of the major sources of the Martian radiation environment. It is important to understand the SEP‐induced Martian radiation environment for future human habitats on Mars.

Evidence for a Past Martian Ring from the Orbital Inclination of Deimos [PDF]
, 2020 We numerically explore the possibility that the large orbital inclination of the martian satellite Deimos originated in an orbital resonance with an ancient inner satellite of Mars more massive than Phobos. We find that Deimos's inclination can be reliably generated by outward evolution of a martian satellite that is about 20 times more massive than ...

Perchlorates on Mars enhance the bacteriocidal effects of UV light
Scientific Reports, 2017 Perchlorates have been identified on the surface of Mars. This has prompted speculation of what their influence would be on habitability. We show that when irradiated with a simulated Martian UV flux, perchlorates become bacteriocidal.

Improving the Accuracy of the Martian Ephemeris Short-Term Prediction
Advances in Astronomy, 2018 The Chinese Mars exploration mission is planned to be launched in 2020, which includes an orbiter, a lander, and a rover. High precision Martian ephemeris is very important in Mars exploration, especially for the Martian orbit insertion and the Martian ...
