Efficient Adaptive Carrier Tracking for Mars to Earth Communications During Entry, Descent and Landing

In the Mars rover missions the signals transmitted back to Earth travel under low SNR conditions in highly non-stationary channels [1, 2]. During the entry, descent and landing phase (EDL), the spacecraft high dynamics yields severe Doppler effects. We pro ...

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 ...

Using an Artificial Intelligence Tool to Perform Science Data Downlink Planning as Part of the Mission Planning Activities of Mars Express

Thomas Léauté

Solving the science data downlink problem for Mars Express (MEX) has been a challenge. An artificial intelligence (AI) based tool, MEXAR2, has been developed and integrated in the mission planning process that allows the user to quickly and effortlessly ge ...

Microscopic four-point probe based on SU-8 cantilevers

Jürgen Brugger, Giovanni Boero, Schahrazede-Lila Mouaziz, Stephan Keller

A microscopic four-point probe (u4PP) for resistivity measurements on thin films was designed and fabricated using the negative photoresist SU-8 as base material. The device consists of four microscopic cantilevers, each of them supporting a probe tip at t ...

Microscopic four-point probe (u4PP) based on SU-8 cantilevers

Jürgen Brugger, Giovanni Boero, Schahrazede-Lila Mouaziz, Stephan Keller

Four-point probes (4PPs) are used for the resistivity measurement of thin metal or semiconductor films. There is an interest in miniaturization of 4PPs to obtain higher surface sensitivity, increased spatial resolution and less damage to the sample. Severa ...

SKY-SAILOR Design of an autonomous solar powered martian airplane

Roland Siegwart

For more than two decades, Mars has been of great interest for scientific exploration, using orbiting spacecrafts or landers. Orbiters like Mars Express cover large areas and give images of the surface with a resolution limited to several meters. Rovers ...

Statistical features of drainage basins in mars channel networks - Can one guess from the landscape the past presence of water?

Paolo De Los Rios

Erosion by flowing water is one of the major forces shaping the surface of Earth. Studies in the last decade have shown, in particular, that the drainage region of rivers, where water is collected, exhibits scale invariant features characterized by exponen ...
