In 2035, humans finally landed on Mars.

A variety of advanced technologies are needed to make a manned flight to Mars a reality. First, a radiation-resistant spacecraft is essential to enable long-duration stays in space. In space, the spacecraft will be exposed to much stronger radiation than on Earth, so it must be designed to protect the safety of the crew. A sustainable life-support system is also essential, as a round-trip to Mars can take several years. Technology that can circulate air, water, and food is key. It is also important to design rovers and habitats that can cope with the harsh Martian environment. The structure must be able to withstand the extreme cold and sandstorms on Mars. In addition, fuel production technology is being developed for Mars. If water can be decomposed to produce fuel locally, there will be no need to transport everything from Earth, which will greatly reduce costs. Finally, another issue is the improvement of communication technology, which is indispensable for manned flight. We need to establish a method to eliminate communication lag between Earth and Mars, which will enable quick response in case of trouble. When all these technologies are in place, humanity will be able to realize the first step toward Mars.
The evolution of space food is a critical issue for the Mars mission. The journey from Earth to Mars will take about six months, and the entire mission will last several years, requiring a nutritious diet that can be preserved for a long time. In addition, the limited space and weight restrictions in the spacecraft must also be considered. Currently, NASA and research institutes in various countries are developing space meals that use 3D printers to prepare food, algae, insects, and other ingredients. These are attracting attention as space-saving, highly nutritious, and sustainable solutions. The taste and appearance of the food is also important for the psychological health of the crew. Successful development of space food that provides not only nutrition but also satisfaction and enjoyment will bring humanity's arrival on Mars one step closer to reality.
Mars is the next frontier for mankind, but its environment is extremely harsh. First of all, the atmosphere is almost entirely composed of carbon dioxide, and oxygen is virtually non-existent. The temperature averages minus 60 degrees Celsius, and dust storms can last for months, which poses a major challenge to Mars exploration technology and human safety. Mars' low gravity is also likely to cause loss of muscle strength and bone density over long stays. Cosmic radiation is another issue that should not be overlooked. Our bodies, protected by the Earth's magnetic field, will need special measures to withstand the powerful radiation environment. To solve these problems, research on durable space suits, radiation shelters, and biological adaptations are underway, but all are still in the early stages.
