[i]Of course, we all know we are going to retire the shuttle. The plan is to retire it at the end of 2010, and what that left us with was a significant gap in our capability to the resources to orbit between the time it retires and, at that time, the planned life of the International Space Station, which is -- our plan is to operate through the end of 2015 and then de-orbit it in the first quarter of 2016. And what we ended up with through our analysis is we found out we needed about 60 metric tons of upmass. And when we look at the vehicles that we have today that are available to us or will be available to us soon, we have, of course, we all know, the Russian Progress vehicle for cargo and the Soyuz vehicle for crew. We recently had the first flight of the automated transfer vehicle, which is the European contribution to payback which we call -- what we call common systems ops cost, and that's going to be four vehicles -- four more vehicles, the first one plus four. And that will be each year starting in '10. So '10, '11, '12, '13 will have an ATV vehicle. In addition to that, we're about to fly our first H-II transfer vehicle, which is the JAXA contribution, also as a payback for common systems ops costs. That will be one per year through the life of the program, starting with their first flight, which is going to occur here in September. Now, all of those vehicles together flying through those times that I just told you about, we still have a 60-metric-ton shortfall.[/i]
