Recallin Week 4 which stated that the ISS alone had cost between US$140 and 160 billion!
Figure 1 shows the cost history of the ISS for the period between the financial years (FY) 1995 and 2002. Note that 2002 has two cost elements – ‘assembly complete’ and ‘core complete’. Please ignore the last column for ‘core complete’ as these values are taken forward into 2004 and 2006.
Now use Figure 1 to complete Activity 1.
