Problem Summary

 

The International Space Station (ISS) is a satellite in low Earth orbit, where scientists since 1998 have been investigating the long-term effects of a zero gravity environment on humans. On July 21, 2011, the final US Space Shuttle landed in Florida. Historically, these space shuttles have been used to maintain the ISS, by bringing up additional modules and by having astronauts conduct routine spacewalks and repairs. Without the space shuttles, we need to find a way to continue maintaining the ISS. We will consider the funds appropriated by the US government and the various methods of taking astronauts up into space in order to develop a comprehensive plan to maintain the ISS until 2021.

 

Background Research: As a group, we initially started out by just trying to understand what the International Space Station (ISS) is, how it functions and all the “basics” that we needed to understand before attacking this problem. We compiled a list of guiding questions and answered them to acquaint ourselves with the problem we were faced with.
