The United States Space Shuttle Program officially ended with the landing of Atlantis in Florida July this year. Without the Space Shuttle, National Aeronautics Space Administration (NASA) will be required to find other spacecraft to transport its astronauts to the International Space Station (ISS) for research and maintenance operations. Our group has developed a comprehensive, ten-year program for NASA that outlines costs, payloads, and flight schedules to maintain the ISS from 2012 to 2021.

 

We first determined the areas that we needed to allocate NASA’s budget to. The four categories we decided on were personnel, operation, research, and resupply. Personnel includes the cost of the astronaut crew (NASA will be reliant on the Russians for transport to the ISS for the duration of the plan and each seat on the Soyuz spacecraft will cost $62.75 million) and the salaries of all of NASA’s astronauts and ground operations crew. Operation includes the operation and maintenance costs for all of the ISS during the plan. As hardware on the ISS will soon exceed their certification limit, total operation costs include equipment re-certification and replacement costs. As it is difficult to determine the cost of the research equipment needed to be transported to the ISS for as yet undetermined research programs, a model of future cost-per-kilogram rates on Commercial Orbital Transportation Services (COTS) was developed to allow calculation of cost by research material mass.
