Systems engineering and design of a Mars Polar Research Base with a human crew

Claudio Leonardi, Anne-Marlene Rüede, Anton Ivanov, Tatiana Maillard

Mars Polar Ice caps have been known ever since they were first observed by Cassini. Robotic exploration mis- sions, starting with Mariner 9, have confirmed that they are composed of water ice. During later missions, instruments such as Mars Global Surveyor ...

Spectral heterogeneity on Phobos and Deimos: HiRISE observations and comparisons to Mars Pathfinder results

Nicolas Le Thomas

The High-Resolution Imaging Science Experiment (HiRISE) onboard Mars Reconnaissance Orbiter (MRO) has been used to observe Phobos and Deimos at spatial scales of around 6 and 20 m/px, respectively. HiRISE (McEwen et al., JGR, 112, CitelD E05502, DOI: 10.10 ...

Order-adaptive frequency trackers for direct-to-Earth Mars communications

Ali H. Sayed

During the entry, descent and landing phase (EDL) of the missions to Mars, the spacecraft's high dynamics imprints severe Doppler swings on the signals transmitted via the direct-to-Earth (DTE) channel. In order to recover the data that record the mission ...

Adaptive Carrier Tracking for Direct-To-Earth Mars Communications

Ali H. Sayed

We propose a robust and low complexity scheme to estimate and track carrier frequency from signals traveling under low SNR conditions in highly non-stationary channels. These scenarios arise in planetary exploration missions subject to high dynamics, such ...
