In order to meet the 2029 deadline and reduce costs, this design will use primarily synergistic applications of NASA’s planned current investments. Additional propulsion stages may be required to decrease the time to Mars as to keep mission costs low and to make the crew not have too much exposure to radiation. Similarly, advanced physics and thermodynamics are unknown in the time of writing this and could potentially allow design flaws from the future design proposal.
To remain conservative, Glenn Research Center (GRC) Collaborative Modeling for Parametric Assessment of Space Systems (COMPASS) had chosen the first of two designs as it was the wider and heavier choice of the two options12. This design similarly will continue to be assumed

It was previously stated that “solar electric propulsion provides such high fuel economy that it reduces the amount of propellant required onboard vehicles for deep-space missions by as much as 90 percent”18. With this statement, alternate ions and configurations have been extensively researched and compared to find the best alternative solution.
One alternative possibility that could be strong considered is Pulsed Lorentz Force Acceleration (PLFA). As a part of this propulsion there is a Lithium Lorentz Force Accelerator (LiLFA) Thruster, which has been proven by research with a power of 500kW to generate a specific impulse (I_sp) of 4000 and an efficiency of 60%18, 19. These characteristics were recorded and demonstrated by V. P. Ageyev, V. G. Ostrovsky, and V. A. Petrosov with the LiLFA engine “operating in this mode uninterruptedly about 500 hours”20 in Russia in 1993. NASA has concurred similar characteristics of Pulsed Lorentz Force Acceleration (PLFA) propulsion system which is described to combine “design elements of the Lithium Lorentz Force Accelerator”21 in addition to quasi-steady Magnetoplasmadynamic thrusters and pulsed plasma thrusters. In the same article, the PLFA is described to achieve a specific impulse of 4800, an efficiency of 60%, max power of 12.5 kW, and a max thrust of 365 mN21. This thruster uses less power than the Xenon thruster in
Space—the final frontier. Ever since the beginning, man-kind has dreamt of escaping the world around us and soaring high, up into the clouds. Many people today still share those same dreams, but they are now looking past the clouds, past the moon to a red planet we call Mars. Three companies are in a race to colonize Mars: NASA, SpaceX, and Mars One. Colonizing Mars will lead to many positive outcomes—new technologies, economic advantages, more jobs, and ideas to avert the population crisis of the future.
The National Aeronautics and Space Administration (NASA) is one of the leading organizations in space technology and research. In the past 60 years, NASA has sent numerous satellites, telescopes and crew modules into space. Despite drawbacks in launch failures and lack of funding, NASA continues to focus on its mission in space exploration and technological advancement. One of NASA’s projects is to explore deep space, in which entails a manned missions to Mars, exploration of the asteroid belt, and beyond. With these goals in mind, NASA has engineered new rocketry and even created a program to better allocate costs of such conquests. With these new advancements, NASA has created a new age of how space travel is carried out.
This source will be used to introduce one of the current theories attempting to explain how the EmDrive produces thrust. The article also addresses the lack of scientific explanation which will help to prove my own credibility in the report as I address a multitude of theories. Because the article was published recently I will likely introduce this source last.

- Member of NASA's 2016 Student Launch, a program where we had to build a rocket around a research or engineering payload and go through an extensive design review process. Along with our initial proposal, our team wrote four design documents and gave corresponding PowerPoint presentations to a team of NASA engineers. Our research project involved examining the effects of he extreme gravitational forces from a rocket launch
In the year 2065, climate change on Earth has spiraled out of control and nations are now fighting for new real estate in space to begin colonization. Mars had been a likely candidate for many years now and was becoming a massive fighting ground for numerous nations. However, it’s arid landscape and small size made it a questionable choice to some. More adventurous and risk-taking politicians urged their researchers to aim for Pluto or planets outside of our solar system. Feeling modern technology was not yet ready for such long distance travel, the United States has chosen to look toward the asteroid belt. As they are setting off, researchers will monitor sunspots to help forecast the behavior of the sun and predict coronal mass ejections (CMEs). Solar-powered sails will make use of solar wind for the early journey after leaving Earth. Radioisotope thermoelectric
Ever since I was a little kid, I looked up at the night sky in awe, fascinated by the infinite wonder of space. I also remember spending countless hours learning facts about space from a science book at my grandma’s house. Today, as a young adult, I look up at the stars, seeing them as destinations. As humanity looks towards Mars, a massive engineering effort will be necessary. Both NASA and private space companies will soon require a plethora of well-educated engineers. I hope to be one of those engineers and am willing to do whatever it takes to ensure that I make my mark on the progress of space exploration.

One major issue with the US Space Program is amount of money it cost to fund the missions but, it is all worth the advancements that we will make. The US Space Program provides space vehicles and different advancements in society. According to NASA,” To enable practical interstellar travel, here are the 3 breakthroughs we’ll need...new propulsion methods...transit speeds...new onboard energy production…”. These new breakthroughs and advancements.
Although space is empty and vast, it contains the most amount of usable energy, the sun. However, even with something so mass and what appears infinite it has its limitations. “The amount of electrical power a spacecraft requires is dictated by the mission. Uninterrupted power must often be supplied for up to 10 years or more.” Solar power requires large equipment and must maintain line-of-sight with the sun, however, solar power has the most concentration of energy. Nuclear power can have large independent output while taking up less space. However, the power, though continuous, is not always constant. Both methods of power are able to sustain equipment energy needs for long journeys across the universe
About 10 years ago, scientists began building an outpost on Mars a few miles from Gale Crater. Robots are maintaining the facility, but their hands are not quite suited for wiring the base. Thus, NASA deemed it necessary to send humans to Mars to get the base running for future missions on an improved version of NASA’s Orion spacecraft. The Orion spacecraft
Amid other things, NASA provides valuable aeronautics research and development when they begin creating a new shuttle or rocket. Charting more and more of space, the program furthers human exploration of our galaxy. When NASA make momentous discoveries, scientists in all fields scramble to strategically analyze and inspect the new data. NASA pioneers the space travel and space technology fields, and it plans to have a human set foot on mars by the year 2025. This lofty goal, which would change science, would improve the way humans view the universe if it is allowed to fruition. Essentially, if NASA continues to operate, science will flourish in the
As coined by the writers of Star Trek, space is widely considered to be the final frontier in human exploration. There are so many advancements that humanity is striving to make in regards to the exploration of this final frontier. Arguably the main goal of humanity at the moment in terms of space travel is to inhabit another planet. That planet is of course our close neighbor, Mars. But with the inhabitation of Mars comes many challenges, which, logically enough, is why it has not happened yet. There are many questions being asked about what technological advances need to be made and what is needed in order to successfully and safely colonize, or even visit, Mars. For instance, do we need to bring water, or can we use the water on Mars? Can humans adapt to an environment with less gravity? How long will it be until a rocket that can realistically be used to transport humans to Mars is operational? All of these questions, once answered, lead to the unavoidable fact that humans will most certainly colonize Mars someday.
Compared with chemical propulsion, it is much safer and more efficient due to jts lesser dependence on propellants to produce the overall same effect. NASA actively propels the development of Solar Electric Propulsion which is a strong sign that electric propulsion is definitely a promising research direction. However, two main problems issues still needed to be solved. Firstly, most of electric propulsion devices are designed for spacecraft; however, low amounts of electrical power are available onboard. Secondly, electric thrusters work with small flows of propellants which result in knockdown acceleration. Both of these could be solved by finding better alternative propellants or coming up with innovative design methods. As one of the world leading technology institutions, Princeton set up the Electric Propulsion and Plasma Dynamics Laboratory to focus on the lithium Lorentz force accelerator. Because of enthusiasm Princeton shows in the electric propulsion and efforts made to push its development, I wish I could have the opportunity to join the Mechanical and Aerospace Engineering Department at Princeton and study with Professor Edgar Choueiri. Also, I am interested in discussing with Professor Craig Arnold’s and Emily A. Carter about their research on clean energy. The advent of the Solar Electric Propulsion will be around 2030 and I hope to spend the next decade working toward its development. My plan is to finish the master’s program in two years and continue to the Ph.D. degree study with an experimental thesis. Afterward, my dream is to continue my research work at Jet Propulsion Laboratory and contribute to the development of better electric propulsion
Space exploration has been a part of human history for more than fifty years. Over this time the exploration of space has produced a continuing stream of benefits, both for society, the environment, etc. From the early years of exploration, it became apparent that it is an efficient driving force for basic science and technology. Further space exploration goals call for sending humans and robots beyond Low Earth Orbit and establishing sustained access to destinations such as the Moon, asteroids and Mars. Space agencies participating in the International Space Exploration Coordination Group (ISECG) are discussing an international approach for achieving these goals. That approach begins with the International Space Station (ISS), and leads to human missions to the surface of Mars. These space exploration missions offer a unique perspective on humanities place in the universe, satisfying our curiosity and inspiring wonder. They provide great opportunities for addressing the many large and seemingly impossible questions such as “What is the nature of the Universe”, "Is the destiny of humankind bound to Earth?", “Are we and our planet unique?”, and "Is there life elsewhere in the Universe?”.
