Why Not Mars (idlewords.com)

Article summary

The article argues that sending humans to Mars with current technology would be a wasteful and destructive endeavor, and that the cost and risk of such a mission outweigh any potential benefits. The author suggests that robotic spacecraft are more capable and cost-effective than human astronauts, and that the pursuit of a Mars landing is driven more by a sense of destiny and adventure than by scientific or practical considerations. The article also discusses the discovery of new forms of life on Earth and the implications of this for the search for life on Mars. The author concludes that NASA's plans for a Mars landing are misguided and that the agency's resources would be better spent on other scientific and technological pursuits.

What commenters say

• Sending humans to Mars is a wasteful and unnecessary endeavor that will not provide significant scientific or practical benefits.
• The pursuit of a Mars landing is driven by a sense of destiny and adventure rather than scientific or practical considerations.
• Robotic spacecraft are more capable and cost-effective than human astronauts for exploring Mars and other celestial bodies.
• The discovery of new forms of life on Earth has significant implications for the search for life on Mars and the potential for contamination of the Martian environment.
• The cost and risk of a Mars landing outweigh any potential benefits, and NASA's resources would be better spent on other scientific and technological pursuits.
• The development of technology for a Mars landing could have spin-off benefits for other areas of science and technology, such as improved life support systems and radiation protection.
• The idea of preserving Mars as a pristine and untouched environment is not a compelling reason to avoid sending humans to the planet, as the universe is vast and human activity will have a negligible impact on it.
• Colonizing the moon first could be a more practical and necessary step before attempting to send humans to Mars, as it would allow for the development and testing of necessary technologies and strategies.
