Problem A:Space Shuttle Problem:No More Space Shuttles
On July 21,2011,the 135th and final US Space Shuttle landed in Florida after its 13-day mission
into orbit,complete with a docking at the International Space Station (ISS).NASA will now
have to rely on other nations or commercial endeavors to travel into space until a replacement
vehicle is developed and constructed.Develop a comprehensive ten-year plan complete with
costs,payloads,and flight schedules to maintain the ISS.
Some interesting facts possibly worthy of your consideration:
• The ISS is at full capacity with 6 astronauts,but can surge during shuttle docks to as high
as 13.
• The ISS is scheduled to remain in service until at least the year 2020.
• Historically,transport to the ISS using US Shuttles has cost between $5000-10,000 per
pound.Shuttle missions have lasted approximately 10-14 days in orbit.Missions on
board the ISS typically last around six months.
• Recently,progress has been made within private industry to launch unmanned rockets
into space.
• Russia is willing to launch US astronauts into space at a cost of about $60 million each

Answer 1

题目中不是说了吗“Develop a comprehensive ten-year plan complete with
costs, payloads, and flight schedules to maintain the ISS”,那你就从costs,payloads和flight schedules来分别讨论嘛.然后下面还给了“Some interesting facts possibly worthy of your consideration”,你自己再结合看看嘛.主要还是自己查资料了,自己建模型,然后看看自己的模型效果怎么样了.不要期待着别人把现成的东西给你,那是不可能也是没意思的,是不是?
