Cultivação Espacial em outros planetas | Yandra Liz | TEDxGreat Intl School

Space Exploration & Colonization - Humanity aims to become an interplanetary society to mitigate risks associated with being confined to a single planet [2] - Mars is a primary target for space exploration and cultivation due to the presence of water (albeit in ice form and toxic) [3] - Martian day length (24 hours 40 minutes) is similar to Earth's, easing astronaut adaptation [4] - Martian temperatures range from 20ºC to -153ºC, comparable to Earth's [5] - Mars has a rotational axis of 2519º, similar to Earth's 235º, suggesting the possibility of seasons [6] - Evidence suggests the past existence of rivers on Mars [7][8] - NASA's MOXIE experiment demonstrates the feasibility of generating oxygen from Martian atmospheric carbon dioxide via electrolysis [10] Terrestrial Benefits of Space Investment - Space program investments indirectly benefit Earth by yielding technologies applicable to terrestrial problems [12] - Apollo program led to emergency blankets and thermal packaging [13] - Mars rovers spurred the development of smaller, more precise cell phone cameras [13] - LandSAT satellites enabled agricultural monitoring, crop forecasting, water resource management, and deforestation detection [14] Potential Applications of Martian Cultivation - Martian cultivation could enable longer space missions by providing astronauts with resources and reducing reliance on Earth [15] - Cultivation in extreme environments like Mars can inform the development of agriculture in Earth's deserts and infertile regions [20] - Hydroponics, crucial for Martian cultivation, could make terrestrial agriculture more sustainable [21] - Space-related cultivation could spur new industries in bioengineering, controlled agriculture, and space equipment [21]
