Could you please help me with this question;

Scientists in the future hope to land a mannea spacecraft on Mars in order to survive on this planet problems associated with lack of air, water, food and shelter must be faced. Select 2 of these problems and describe how you think they might be overcomed.

I will be happy to critique your thinking on this.

To overcome the problem of lack of air on Mars, scientists may consider developing different methods. One possibility is utilizing a process called terraforming, which involves modifying a planet's environment to make it habitable for humans. In the case of Mars, scientists could introduce greenhouse gases, such as carbon dioxide, into the atmosphere to create a thicker atmosphere and increase the air pressure. This would enhance the greenhouse effect, trapping heat and potentially leading to the melting of frozen water on the planet's surface, thereby releasing oxygen. Alternatively, scientists have proposed creating an artificial closed-loop system within the spacecraft or establishing habitats on the planet that use advanced life support systems to recycle and regenerate the available air supply.

As for the problem of lack of water, scientists can explore several possibilities. One approach is to search for underground water sources on Mars, such as groundwater or ice deposits. Once located, techniques like drilling or extraction can be employed to access and utilize these water resources. Another option is to develop advanced water purification and filtration systems capable of extracting and purifying water from the Martian soil, atmosphere, or even from moisture contained in the spacecraft itself. Additionally, scientists can also consider deploying technologies like "hydroponics" or "aeroponics" that enable the cultivation of plants, using minimal water and nutrient solutions, to provide a sustainable source of food while also recycling water.

It's important to note that these are speculative approaches and may still require significant advancements in technology and substantial research before they can be implemented effectively.
