Mars and organic matter:-
Seasonal Methane Releases: - Scientists describe the discovery of seasonal variations in methane in the Martian atmosphere over the course of nearly three Mars years, which is almost six Earth years. This variation was detected by Curiosity’s Sample Analysis at Mars (SAM) instrument suite. Water-rock chemistry might have generated the methane, but scientists cannot rule out the possibility of biological origins. Methane previously had been detected in Mars' atmosphere in large, unpredictable plumes. This new result shows that low levels of methane within Gale Crater repeatedly peak in warm, summer months and drop in the winter every year. (organic molecules could be created by non-biological processes which aren’t necessarily indicators of life) ·Robot Details: - … In order to increase NASA database about the Organic matter and the humidity levels in several areas in Mars, we designed a robot that is able to measure the methane gas which is a great indication of organic matter in any planet in addition to humidity. These measurements open the possibilities of ancient life on mars as well as irrigation. All the project and prototype description will be displayed below:
· Bluetooth module: to control the movement of the prototype only.· Soil moisture sensor: Calculate the humidity of the soil according to variation of its resistance which cause a variation on the voltage which the Arduino read as an analog signal. · LDR: An LDR is a component that has a (variable) resistance that changes with the light intensity that falls upon it. Consequently, the voltage of the circuit changes and this enables us use it in our robot for light intensity sensing because we can know the intensity of light on mars by reading the voltage of the circuit. · Monitor: Its function is to display the data received from the temperature and MQ-2 gas sensors. · Driller: As we will control the robot from earth using remote-controlling devices, we supplied it with a driller to take some samples from Mars’s ground when we give it order to do so. In addition, we will use this ability to measure the humidity of the ground because the robot will insert the electrodes of the humidity sensor in the position we ordered it to drill and measure the humidity of this area.
