The reading passage claims that space tourism will become a widely popular industry, providing exciting travel opportunities, contributing to scientific advancements, and boosting the economy. However, the professor in the lecture challenges these claims, arguing that space tourism is not as promising as it seems. First, the reading states that space tourism will offer people a once-in-a-lifetime experience, allowing them to travel beyond Earth and view space firsthand. However, the professor refutes this claim by explaining that space travel is extremely dangerous. He points out that even trained astronauts face significant risks, including exposure to radiation and the possibility of technical malfunctions. Since tourists lack the training and experience of professional astronauts, the risks involved in space tourism make it less appealing than the reading suggests. Second, the reading suggests that space tourism will contribute to scientific research by funding space exploration and helping scientists gather data from outside Earth’s atmosphere. In contrast, the professor argues that space tourism could actually hinder scientific progress. He explains that prioritizing commercial flights over research missions could divert resources away from important scientific projects. Additionally, he warns that an increase in space travel could lead to space debris accumulation, which poses a long-term threat to future space missions. Finally, the reading claims that space tourism will generate significant economic benefits by creating new jobs and attracting wealthy travelers willing to pay high prices. However, the professor challenges this idea, stating that space tourism will only benefit a small group of wealthy individuals and companies, rather than the general public. He explains that the cost of space travel is so high that only the richest people can afford it, making it an exclusive luxury rather than an industry that benefits the economy on a larger scale. In conclusion, while the reading passage presents space tourism as an exciting and beneficial industry, the professor disagrees. He argues that the dangers of space travel, the potential harm to scientific research, and the economic exclusivity of the industry make space tourism far less promising than the reading suggests.
