Colonizing Mars In Class Exercise 2 Pointscomplete This Assignment I

Complete this assignment in lieu of class on October 19. Watch TED talk video and take notes on the following questions. Notes do not count towards grade: a. According to Mr. Petranek, why must humans colonize Mars? b. What are the engineering challenges of going to Mars? c. What are the engineering challenges of living on Mars and how might these be resolved? d. What are the humanitarian and ethical issues associated with sending humans to Mars?

Set a timer for one hour. Within that hour, write one short paragraph (up to 5 sentences) for each question 1.a. to 1.d. Aim to write a cohesive text that ties each paragraph to the previous paragraph. Mention Mr. Petranek as the source at an appropriate location in the text and add a footnote with the link to the video. Reserve extra time to read and edit your paragraphs for clarity and conciseness.

Paper For Above instruction

The compelling need for humanity to establish a presence on Mars stems from both the desire for survival and the pursuit of scientific advancement, as emphasized by Mr. Petranek in his TED talk. He argues that Earth faces existential threats such as climate change, planetary collisions, and resource depletion, which could jeopardize human civilization. Colonizing Mars offers a backup plan for humanity, ensuring our species can survive catastrophic events that might wipe out life on Earth. This perspective underscores the importance of expanding beyond our home planet, embracing space exploration as a vital step in humanity's long-term future.

However, the journey to Mars presents formidable engineering challenges that require innovative solutions. According to Mr. Petranek, one major hurdle is developing propulsion systems capable of transporting humans safely across the vast distance—approximately 225 million kilometers—while minimizing transit time and radiation exposure. Life support systems must be robust enough to sustain human life in the harsh environment of space and on Mars's surface. Moreover, designing spacecraft and habitats that can withstand extreme temperatures, radiation, and dust storms demands cutting-edge engineering. Overcoming these challenges is essential to enable safe and sustainable human travel to and from Mars.

Living on Mars introduces additional engineering difficulties that necessitate advanced technological solutions. The thin atmosphere, composed mostly of carbon dioxide, provides no breathable air, requiring habitats to include efficient life-support systems that produce oxygen and recycle waste. Water scarcity is another concern, as the available supply must be managed carefully or extracted from local resources such as ice. To address these issues, habitat designs may incorporate renewable energy sources like solar panels, along with shielding to protect residents from radiation. Developing closed-loop life support systems and in-situ resource utilization will be vital for creating a sustainable human presence on Mars, as suggested by Mr. Petranek.

Ethical and humanitarian issues surrounding Mars colonization pose significant debates about our responsibilities and moral obligations. Sending humans to an uninhabited planet raises questions about planetary protection, potential contamination, and the preservation of extraterrestrial environments. There are concerns about exploiting Mars's resources and the possible impacts on any extant microbial life, if present. Additionally, ethical questions about prioritizing space exploration over addressing urgent issues on Earth—such as poverty and climate change—must be considered. The decision to colonize Mars must involve careful deliberation about how to balance exploration benefits with ethical responsibilities, as discussed by Mr. Petranek in his talk.1.
