Space Tourism Feasibility Study

题目与答案

1. 21 What surprised Mark most about the history of space tourism?
   • the extremely early dates of the original proposals
   • the astronomical cost of the initial test flights
   • the lack of public interest in the early stages

   答案：the extremely early dates of the original proposals

   原文定位：I was looking at early proposals. You’d think the astronomical cost of initial test flights would be the most shocking thing. But honestly, what really blew my mind was just how far back the original concepts were drafted; I had no idea people were seriously planning this decades ago

   同义替换：「what really blew my mind」↔「surprised most」，「decades ago」↔「extremely early dates」

2. 22 Lena argues that the biggest challenge for current space tourism companies is
   • finding enough civilians willing to risk the journey.
   • securing sufficient funding from government bodies.
   • developing launch vehicles that are completely reliable.

   答案：developing launch vehicles that are completely reliable.

   原文定位：Many articles claim that finding civilians willing to risk their lives is the main barrier. Actually, there is a huge waiting list. From what I’ve researched, the absolute biggest hurdle these corporations are struggling with is actually engineering launch vehicles that won’t fail; ensuring that level of reliability is the bottleneck

   同义替换：「corporations」↔「companies」，「absolute biggest hurdle」↔「biggest challenge」，「won’t fail」↔「completely reliable」，「engineering」↔「developing」

3. 23 What do Mark and Lena agree must happen regarding the environmental impact?
   • The industry could be shut down due to public backlash.
   • Companies will be forced to utilize eco-friendly propellants.
   • Regulatory bodies will ban short-duration tourist flights.

   答案：Companies will be forced to utilize eco-friendly propellants.

   原文定位：Yeah, safety is the priority. And then there’s the environmental side. I honestly think the backlash over emissions could shut down the whole industry;I don’t think it’ll be banned completely. But regulatory bodies will force them to innovate. The only viable way forward is for companies to transition completely to developing eco-friendly propellants;You’re right, shifting to greener fuel types will be mandatory

   同义替换：「forced」↔「mandatory」，「utilize eco-friendly propellants」↔「transition to developing eco-friendly propellants」

4. 24 For their presentation on ‘passenger preparation’, they decide to focus on
   • the standard physical fitness tests.
   • the psychological conditioning required.
   • the emergency procedures and protocols.

   答案：the psychological conditioning required.

   原文定位：Okay, what about the section on passenger preparation? I was thinking we could discuss the physical fitness tests they have to pass;We could, but the physical stuff is heavily documented. What’s much more compelling, and what the class would find unusual, is how they get civilians mentally ready to be in such a confined, hostile environment. Let’s focus on that

   同义替换：「mentally ready」↔「psychological conditioning」

5. 25 They agree to conclude their feasibility study by examining
   • the projected timeline for regular commercial operations.
   • the potential for future destinations like Mars.
   • the changes needed in international space law.

   答案：the projected timeline for regular commercial operations.

   原文定位：Great. And for the conclusion? I’d love to talk about where we might go next, like hotels on the Moon or potential Mars bases;Those destinations are exciting, but maybe too sci-fi. It would be much more grounded to end by analyzing exactly when these companies realistically expect to start regular, scheduled commercial operations

   同义替换：「conclude their study」↔「end by analyzing」，「projected timeline」↔「expect to start」

6. Launch noise
   • implement fully automated systems
   • construct offshore facilities
   • utilize computer-simulated environments
   • employ 3D printing technology
   • develop pill-based nutrition
   • restrict overall flight durations

   答案：construct offshore facilities

   原文定位：One paper suggested restricting flight durations, but that doesn’t solve it. The most viable proposal is constructing the launch pads out at sea, away from major cities

   同义替换：「offshore facilities」↔「pads out at sea」

7. Passenger motion sickness
   • implement fully automated systems
   • construct offshore facilities
   • utilize computer-simulated environments
   • employ 3D printing technology
   • develop pill-based nutrition
   • restrict overall flight durations

   答案：utilize computer-simulated environments

   原文定位：Instead of drugs, the new approach is to have passengers use computer-simulated environments before the flight, so their brains adapt to the visual disconnect

8. Spacesuit design
   • implement fully automated systems
   • construct offshore facilities
   • utilize computer-simulated environments
   • employ 3D printing technology
   • develop pill-based nutrition
   • restrict overall flight durations

   答案：employ 3D printing technology

   原文定位：The breakthrough there is using additive manufacturing. They can scan a person’s body and just manufacture the suit layer by layer on demand;using 3D printers will cut costs

9. Food storage
   • implement fully automated systems
   • construct offshore facilities
   • utilize computer-simulated environments
   • employ 3D printing technology
   • develop pill-based nutrition
   • restrict overall flight durations

   答案：develop pill-based nutrition

   原文定位：compressing all the essential daily vitamins and calories into a tablet form, which saves massive amounts of space and weight

   同义替换：「pill-based nutrition」↔「tablet form」

10. Waste management
    • implement fully automated systems
    • construct offshore facilities
    • utilize computer-simulated environments
    • employ 3D printing technology
    • develop pill-based nutrition
    • restrict overall flight durations

    答案：implement fully automated systems

    原文定位：The recommendation is to install self- contained, robotic disposal mechanisms that handle everything without human intervention. Lena: Agreed, relying on automated machinery is the safest option

    同义替换：「fully automated systems」↔「automated machinery」
