Space Apps Challenge 2018

In space mission to Mars, the meteorological condition and the accidents present risks to the equipment used. In order to find a solution, the team Sirius has thought in a way to provide greater safety to the crew chosen for future missions, and also, exploration probes sent to Mars, ensuring greater control against possible unforeseen.

Thus, in this way, arise the WS-Mars, a sensor whose main objective is to continuously test the integrity and resistence of materials exposed to adverse conditions of the red planet, such as constant sandstorms and thermal variation, guaranteeing its reliability in short and long term use. The exposure to sandstorm, which is more common during the perielium, when the planet receive 40 more sunlight is a risk factor to be taken in to consideration. The storms that can last for long periods and whose winds reach speeds above 160km/h that although its inertia is attenuated due to the lower atmospheric pressure of (600 pascal, compared to approximately to 101000 a.p. of the Earth ) represent a threat to the integrity of materials due to the abrasion generated by long-term kinetic friction. Another point we should taken in consideration is the extreme temperature variation on Mars, that can also present risks to the long-term durability of materials.

According to Nasa data, Mars has extremely low temperature conditions, reaching -140 degrees Celsius in Winters and 30 degrees Celsius in Summer. We have noticed that among the sensors that are displayed on the Rover from Mars mission 2020, there is no Tool to measure the wear material. Under these circunstances the system was developed on a prototyping platform, in order to report a failure on a particular line of the circuit, obtaining guidance in engineering circuits on degradation in material such as tines and brake disks.

This technology can be installed at key points in the layers of the space suite or at critical points of instalation. Thus, the information collected will be available on the equipment itself, or monitored remotely by mission control center . The energy consumption of this prototype may be as low as possible, since the date processing for this procedure need not be Swift. These sensors will indicate how damaged was the equipment and when is necessary its exchange.
