The challenges faced to operate a UAS on Mars can be broken down into 3 areas of delivering the UAS to Mars, operating in the Martian atmosphere, and supporting the UAS. Each area will have unique requirements which can vary based on several factors. For example is the UAS being delivered as a stand alone platform or is it to be operated from a manned based with support? This discussion will focus on a stand alone platform and assume there will be no manned support. Also the mission will remain generic, but we will assume our UAS will carry some kind of sensor payload to perform a mission.

Delivering the UAS to Mars will require a craft to bring it into the Martian atmosphere and then deploy the UAS into the air or launch it from the ground. This can be done as a standalone deployment or as a piggy back on another mission such as a rover. NASA is designing and testing the Prandtl-m UAS for a flight on Mars which would be deployed at altitude from an aeroshell of a future Mars rover (Levine, 2015). The other option would be to have an aeroshell deliver the UAS to the surface similar to a rover where it would then be launched. …show more content…

On Mars the general theme is the environmental parameters such as gravity, atmospheric pressure, and temperature are lower and specifically the atmospheric density at sea level is approximately one one-hundredth of that on Earth. (Dhanji, Dupuis, & Nahon, 2006). The result is less lift is generated and therefore the UAS must have larger surfaces or higher thrust than it have on Earth. The temperature on Mars is also considerably lower than that on Earth and will have a possible degrading effect on components such as sensors and batteries. Finally, the gravity is lower on Mars, which will mean payload and aircraft weight will differ from that on Earth (Levine,

In the novel The Martian by Andy Weir, there are various connections between the book and real-life events. Firstly, NASA has conducted expeditions to Mars in real-life, similar to the book’s events. “I dug out one of the rovers and had a good drive around, but after days of wandering, I think it’s time to give up.” (Weir 14). Weir takes inspiration from many real-life Mars rovers, such as Spirit and Opportunity.

Anti-aircraft weapons were used to shoot enemy planes out of the sky. Carbines are shortened, more compact automatic rifles and are used to approach without the loss of fire power. UAV/Drones are unmanned vehicles that are usually used to gather intelligence or to bomb specific targets. Bombers are of course used to bomb cities, targets or

Some of the possibilities NASA has for Mars are, as the article says, “plans for radiation shielding, centrifugal artificial gravity, in-transit consumable resupply, and a return-lander.” (Williams) This quote explains a few possibilities of how NASA could colonize Mars. Any of these possibilities could potentially work in the future. An advantage humans have with Mars colonization is that the days are similar.

NASA currently has several missions, including the Mars Exploration Rover Opportunity, Spacecraft Fire Experiment-I (Saffire-I), Glenn Research Center’s Icing Research, the James Webb Space Telescope, and Dawn. However, NASA is not the only force in space, as seen by the progress of several private companies. NASA’s budget could be the key to change within NASA’s programs. One NASA mission in exploration is the Mars Exploration Rover Opportunity. Opportunity was launched on July 07, 2003, at 11:18 p.m. EDT, landed on Mars on January 25, 2004, at 04:54 UTC, and is still roaming the planet today.

Traveling to Mars has been in the minds of the American people since the Apollo moon missions of the 1970s. It seemed as if the natural progression of the space program would be to explore Mars next, or at the bare minimum, continue exploration of the moon. However, space exploration has seemingly ground to a halt. Aerospace engineer and author, Robert Zubrin is an acclaimed professional in the concept of sending humans to Mars. He is a strong advocate of reinvigorating human space exploration and establishing a colony on the red planet to expand human influence into the solar system.

Phase 1 will involve quantitative data collection with a follow on qualitative phase 2. This method is appropriate since it will allow the researcher to collect and analyze numerical data, then use a qualitative approach to better understand the statistical results and to make conclusive recommendations. In phase 1, the DroneShield system will be set up, initial conditions uploaded and checked, and then testing will involve three locations types: a rural flat environment, rural hilly, and a dense urban tall building environment. Next, four types of small UAVs will be flown into the detection zone at various altitudes and from various directions.

This is a police drone that has been helping law enforcement to find criminals or find lost hikers. This technology is so cost efficient that it replaced helicopters. Ben Miller, Director of Mesa County’s UAV program said, “We can fly 50-60ft off the ground and literally photo-map an entire crime scene.” (Cited, Lev Grossman 2013) It is a great little-advanced tool to document crime scenes more accurately, help to find clues quickly to prosecute criminals.
