The most important technical breakthrough landing of Mars and Mars Rocket Design
Aerospace Science and Technology to the development of science and space technology today, rely mainly on the modernization of modern physics, astronomy, geology, biology, computer technology, materials technology, mechanical and electrical integration, electronic communications, information technology, nutrition, food, aerospace and technology many, machining, metallurgy, casting technology, automation technology, programming, technology, marine technology, medical technology, mathematical logic, remote sensing technology, precision manufacturing technology, instrumentation technology, the limits of technology, nuclear chemistry, etc. disciplines and professional categories cross comprehensive, high precision, sharp, partial, special, unique, high-tech intensive, criss-cross, a huge investment in R & D funding, a lot of difficulty doubt, the vast majority of the most cutting-edge technology integration, test, design, manufacture, testing, testing ,, industrialization experiment, forming stereotypes, such as product and technology.
Countries in the world, the United States, Russia, China, Europe, India, Japan, Arab and other countries have invested a lot of human material and financial resources, research and development strengths and weaknesses. Among them, the United States took the lead, far ahead, topped the list. Explorations and studies of Mars, more successful. Technical strength and overall strength second to none, followed by Russia, Europe and China followed.
Now mainly manned Mars landing on Mars, the moon is far better than a hundred times difficult, dangerous times. They invested hundreds of billions of dollars, a huge investment. And risky, success and failure coexist. Flight detector detects far much easier than manned flight, and whether successful or not, does not involve the lives and safety of the astronauts return. Manned flight is required to ensure the health and safety of the lives of the astronauts, otherwise, never to return, the man-machine died, or been heard, lost contact without a trace. Airlines lost contact with the plane crash, the difficulties missing accidents everywhere, not to mention aerospace space flight, the risk of accidents harder to avoid. Various risk assessment to Mars, much larger than fly to the moon or space station. Therefore, an important technical breakthrough Mars rocket and overall design fateful decision success or failure.
The overall design attached safety-aided design (A) rocket
(B). Rocket power to rely on traditional fuels, but also to configure the new compensation power switch.
(C). Rocket Segment, member configured with a safe alternative design techniques.
(D). Overloading, high speed, safety is the focus of the new rocket design.
(E). Rocket and spacecraft design and manufacturing materials design spacesuits radiation glued.
(F) necessary to reload, but also to ensure the rocket body, not too heavy, bulky, failure to avoid accidents.
(G). Often wearing parts and spare parts versatility interchangeability. Maintenance of sensitive components of maintenance and repair.
(H) escape system is equipped with double-entry system.
(I). Rocket crisis, auxiliary spacecraft can start to return.
(J) in the rocket and the spacecraft’s life support systems and emergency medical systems overlap and complement each other.
(K). Rockets own detection and prevention system in the long flight.
(L). Rocket and the spacecraft upon arrival at Mars, landing design techniques, the use of double insurance design, lander weighing several tons or several tens of tons. Recommendation manned lander minimize weight, mainly manned landing; cargo landed or reloadable rocket cargo equipment. Therefore, Mars rocket should fly binary, one cargo, one manned rocket if any risk of failure, the two alternative safe return. Binary rocket into account both the overall design versatility, interchangeability of emergency. Of course, the binary operating costs to be much larger rocket, the first manned landing on Mars investment is essential, otherwise, the greater the cost and the cost of failure and loss of pay, the latter is several times higher several times. Large heavy-duty rocket integrity, and cost less than binary rockets, however, relatively bulky, safety and reliability Mars voyage is less than medium and small rocket rockets, it intends to use binary comparison solid rocket flight. Mars and the moon, after all, very different, and potentially dangerous accident risk is far greater than the latter, especially nourishing and astronauts landing on Mars on Mars need to add a few years of life, etc., you can return astronauts to the moon after landing. Of course, special design considerations can also be used to return to the moon and timely manner. But copying the way the moon difficulties surge in the limited time, the change in distance, immediate return is difficult to make the trip. Astronaut tired, hurried past, prone to all kinds of dangers and accidents. Therefore, the Mars landing spacecraft rocket technology using picture-contrast, low risk, safety factor, reliability geometric single rocket better than many, but the cost is bound to increase. Especially humans first manned landing on Mars, a surefire plan is the best policy. Large rocket to Mars direct cost of about 50 billion -700 billion (direct costs, indirect costs of research and development costs extra), binary picture rocket is about 100 billion -1200 one hundred million US dollars .. This is a preliminary estimate, the actual figures may be slightly higher or lower them. Of course, a variety of programs unique to selective advantages. Starting from cost reduction, single rocket landed also has its benefits, it can be neglected.
(M). Mars survive life-sustaining support system.
(N). Mars rover intelligent multi-purpose, Mars truck. Software program designed to have a dual system backup and manual control operation system.
(O). Mars landing aircraft or ground lift rocket. Miniature nuclear reactor can be a conventional fuel or the like. Landing can be lifting flight. Starting rocket maintenance and repair. Back cabin technical support. Lifting can launch a rocket and mothership will then also be on their own long-distance return flight. Selection of design parameters is very important, especially starting manned rocket and cargo rocket design is very different.
(P). Mars Auto workstations, automatic monitor. Unattended around the clock work, Mars Communications status information, to avoid high-risk radiation, dust storms and extreme environmental changes interference. Interstellar communications relay. Solar cells or batteries and other nuclear energy supply.
(Q). Mars life support system. Food and Nutrition Mars, Mars planting. Mars life support care system.
(R). Unforeseen accidents and dangerous self-help self-help system, emergency response systems.
(S) technical parameters rocket design: the initial thrust to weight ratio than the specific impulse load per unit area than
(T) sub-structure coefficient
(U) off mass equation:
Safety margin (V) Build quality flight propellant mass consumed propellant mass loading coefficient consumed before take-off into the left
(W) Overall design and technical solutions technical route at stake. Directly related to the success or failure of Mars and safe return. In addition to the substantial investment, overall planning and design layout, the overall technical route and technical solutions as well as the overall design, and so a lot of thousands of sub-sub-polymerization technology integration, compatibility with a variety of techniques unique fusion of alternative support should be OK possess and perfect.
Major human landing on Mars unprecedented initiative, especially first manned flight and safe return to Earth at stake, significance. Human landing on the moon was a great one small step out of the earth, then the human landing on Mars and return safely to Earth is humanity taken a big step. Its meaning is far more than the year Columbus discovered the New World, Christopher Columbus discovered because just the inside of the Earth, Mars and the Mars immigration boundless expanse of the universe is the universe of the natural world. Both quite different. From Galileo’s telescope invention, Copernicus, Tsiolkovsky, mankind has gone through several hundred thousand years, until Gagarin first flew the Earth, the moon and the United States successfully returned safely to Earth, human footsteps moment It has not stopped. March to the moon, to Mars marching to Venus, Mercury, Jupiter, marching to the Galaxy, its overwhelming. In fact, the human race and Zeus in the race and the universe, this is a great show high intelligence and special nature of animal life aggressive. This is of special significance at the level of a natural substance, and on human societies and world level, its great significance would be immeasurable, influencing and changing the whole world of mankind and human history.
