Machines, not people, should be exploring the stars for now
Why does the author believe that robotic space exploration is better than manned space exploration for now? Provide two pieces of evidence from the text to support your answer.
The author believes that robotic space exploration is better than manned space exploration for now for the following reasons:
1. Efficiency: The author states, "Robotic exploration is more efficient and cost-effective than manned missions." This suggests that machines are able to explore space in a more resource-efficient manner compared to humans. Robotic missions can be designed specifically for scientific objectives without having to accommodate human needs such as life support systems or provisions for long-duration space travel, thus making them more efficient in achieving their goals.
2. Safety Considerations: The author points out that "robotic missions can also venture into environments too dangerous for humans, such as the intense radiation belts around Jupiter." This indicates that machines can be sent to explore hazardous or hostile environments where human presence would be risky or even fatal. This prioritizes safety by utilizing robotic missions to gather information from locations that may pose potential harm to human astronauts.
Overall, the author believes that robotic space exploration is currently preferred due to its efficiency in achieving scientific objectives and its ability to explore hazardous environments without risking human lives.
