NASA Proposal

Many scientists, engineers, and politicians have proposed wondrous ideas about missions to Mars. This mission called ‘Project Global’ will be a long term exploration on the Martian surface in order to find sustainable future life habitats on Mars. Earth is our natural habitat. It is passed from one generation to the next. What our future children will have depend directly on the generation of ours, thus it is our responsibility and duty to care for our environment today. Environmental issues here on Earth such as global warming, depletion of natural resources, and water pollution have resulted from human activities. One solution to these to these problems is environmental conservation, which is the use of natural resources to ensure enough for the future and minimal damage to the environment. However, it is our responsibility to find a suitable living before the natural resources run out at a later date. The mission objectives, timeline, landing site, rover specifications, instruments, and experiments will contribute to the Project Global proposal.

  • 1. Many scientists, engineers, and politicians have proposed wondrous ideas about missions to Mars. This mission called ‘Project Global’ will be a long term exploration on the Martian surface in order to find sustainable future life habitats on Mars. Earth is our natural habitat. It is passed from one generation to the next. What our future children will have depend directly on the generation of ours, thus it is our responsibility and duty to care for our environment today. Environmental issues here on Earth such as global warming, depletion of natural resources, and water pollution have resulted from human activities. One solution to these to these problems is environmental conservation, which is the use of natural resources to ensure enough for the future and minimal damage to the environment. However, it is our responsibility to find a suitable living before the natural resources run out at a later date. The mission objectives, timeline, landing site, rover specifications, instruments, and experiments will contribute to the Project Global proposal. The first mission objective is to learn everything that there is about the planet Mars including Mars’ structure, chemical makeup, temperature, and atmospheric conditions. By going to Mars and analyzing everything there is to know, then the most important knowledgeable information can be brought back to Earth in order to share it with our upcoming future generations. This will benefit our society with education, which is the forefront of everything. Without education nothing will succeed correctly. Education will help people get the jobs they want in order to put people back to work. Schools can expand with specific classes targeted at engineers and scientists to put forth applied ideas to practical work situations. For example, an engineer would have a hard time designing a way for a rover to land at a specific surrounding on a planet. A solution to this problem would be to use mathematics and physics to calculate the trajectory for a precise landing. When we are armed with education, then we can steer ourselves in any specific direction in order to accomplish many goals. Another mission objective is studying the Martian environment. Scientists have already discovered Earth bacterium that can survive in a similar Mars’ environment. It is a microbe that can survive in places without oxygen like down a cow’s stomach. The soil was very close to the dirt of Mars. The result was a thriving colony of methane-producing bacteria. Methane is a greenhouse gas meaning that it can warm the surface. In order to find life on Mars, there needs to be water. There even may be enough natural resources on Mars to bring back to Earth and save our planet from global warming or using up our own natural resources. The final mission objective is to evolve advancing technology. This is the most important goal. As evolution progresses from the caveman to the robot and beyond, humans will have to adapt as time changes. For example, as population growth increases here on Earth, demand for resources will create pressure for humans to colonize new habitats. Terraforming, a process by which the climate, surface, and properties of Mars would be changed with the goal of making it habitable by humans, will provide a safe and supportable colonization of Mars. This would be a possible solution in order to make Mars habitable long before a deadline here on Earth. Hydrogen importation could be done for atmospheric and hydrospheric engineering. For instance, the hydrogen from the Martian soil could react with iron (III) oxide to give water as a product. Since Mars is made of mostly carbon dioxide, importation and the reaction of

The timeline is an important aspect to consider because it will help the Johnson Space Center in Houston, Texas stay organized with leaving Earth, arriving on Mars, staying on Mars, departing from Mars, and returning back home. Rover ‘Envy’ will be launched from the Kennedy Space Center in Cape Canaveral, Florida on October 1, 2013. It will then travel for a six month trip to Mars. It will arrive on the Martian surface on April 14, 2014. While it is there, Envy will then stay on Mars for twenty Earth months gathering data, collecting soil, analyzing the surface, checking atmospheric conditions, and finding water. Envy will then depart from Mars on December 31, 2015. It will arrive back to Earth on June 7, 2016 where scientists will begin to study the evidence of life on Mars from the soil, chemistry, and weather system. Once all of this information is gathered and put forth, many jobs will be created. The educational system can benefit from this by accepting any and all determined students in order to better themselves for their family, organization, and the public. Industries would also send employers such as environmental or chemical engineers back to school with a promise of a future job opportunity. Envy will be projected onto a landing site within a 120 mile radius of the Korolev crater. This part of the planet has a less rugged and scarred terrain than the majority of the planet. There are seven major craters within this radius. The rover will be encased inside of a balloon cushioned shell (BCS). Once it enters the Martian atmosphere, computers will initiate the balloons to cushion the impact landing. When the momentum of the (BCS) comes to a halt, the balloons will deflate allowing the rover to be accessible to the environment. Envy will land in this area with the hope of finding ice under the craters. The coordinates for the landing site are 70°03’59.34”N 155°50’08.58”E. Landing there will be the most challenging part of the mission. It will be important to land on the smoothest possible surface, because it will also be helpful to launch back into space. Harsh conditions such as high speed winds, dust storms, tornadoes, and possible rockiness need to be taken into consideration. This type of landing site will offer a good geological and potential exobiological diversity. There are many rover specifications like propulsion, energy, communications, guidance, instruments, and experiments. Envy will be built and flight tested by engineers in Pasadena, California at the Jet Propulsion Laboratory. A wheel and axel systemwill be built in order for the rover to propel and move. It will be driven by the motors. High efficiency solar cells will provide the power required for the duration on Mars. These cells will convert solar energy into electricity. Envy will consistently clean the dust off the dirty panels for cleaner energy. Envy’s energy supply will be about 30 watt-hours to about 210 watt-hours. The rover will use about 180 watt-hours per day for basic survival and communications. The rover will be guided and controlled by computers through the communications system. Space communications systems are highly dependent on the frequency and wavelength used for communication. The lower the frequency and the longer the wavelength, the greater will be the impact of man-made interference and solar and galactic noise on the system. At lower frequencies the ionosphere also reflects more transmitter power back toward the earth. Also, antennas will become larger

Microwaves are considered to begin at about 1 Gigahertz (30 centimeter wavelength) in the (UHF) band and extend through the (SHF) band to 30 Gigahertz (1 centimeter wavelength). Frequencies Waves Ranging from Wavelength Very High Frequencies (VHF) Metric 30 Megahertz to 300 Megahertz 10 Meters to 1 Meter Ultra High Frequencies (UHF) Decimetric 300 Megahertz to 3 Gigahertz 1 Meter to 10 Centimeter Super High Frequencies (SHF) Centimetric 3 Gigahertz to 30 Gigahertz 10 Centimeter to 1 Centimeter Extremely High Frequencies (EHF) Millimetric 30 Gigahertz to 300 Gigahertz 1 Centimeter to 1 Millimeter Envy’s dimensions and weight are similar to NASA’s Spirit rover. Envy will measure 5.0 feet in length, 7.5 feet in width, and 4.8 feet in height. The total weight of the rover at launch time is 2250 pounds consisting of a 350 pound rover, 800 pounds of the lander, 400 pounds of back shell, 200 pounds of heat shield, 100 pounds of fuel, and 400 pounds of the cruise stage. Chemistry experiments such as fractional distillation can be used in order to extrapolate a certain liquid for laboratory analysis. Project Global will be a significant step in improving America’s economy. It will put all types of people back to work. From everybody working together to benefit a common goal, the world will be a better place. There are many challenges for engineers and scientists, but the implemented work will make the world better than we already have. The main goal to accomplish in the distant future is terraforming, an idea that will work for us when the deadline for natural resources is approaching here on Earth. It is going to take all of us working together in order to make these accomplishments.
