The ISS is the only crewed space station in orbit. Due to be completed in 2011, the ISS is also the most active and massive space station ever deployed. NASA, a main contributor, received $## billion for the ISS in fiscal year (FY) 2010 compared to $## billion approved by Congress in FY 2009. This funding does not include flight or ground operations costs of shuttle flights to and from the ISS. Two new modules were added to the ISS during 2010. In February, Space Shuttle Endeavour delivered the Tranquility module, which contains life support systems and a unique seven-windowed cupola from which astronauts can conduct robotic operations.
The largest in-space platform is the International Space Station. NASA, the main contributor to the ISS, received $## billion for the station in fiscal year (FY) 2010 compared to $## billion approved by Congress in FY 2009. This funding does not include flight or ground operations costs of shuttle flights to and from the ISS. During 2009, two major modules were added: the final truss segment and a section of the solar array. The truss acts as the junction through which external utilities, such as power, communications, and ammonia for thermal control systems, are routed to the pressurized modules.
Funding for the largest in-space platform, the International Space Station, is included in the government budgets of ISS partners. NASA, the largest contributor, allocated $## billion for the space station in fiscal year (FY) 2008 and requested $## billion for FY 2009. During 2008, two major modules were added to the ISS: the Japanese Kibo, which cost approximately $# billion to develop; and the European Space Agency’s (ESA) Columbus, which cost €880 million (US$## billion).
