For example, the Methane engines are a nice element that would be beneficial for future Mars missions, but removing that from the critical path to the Moon now reduces uncertainties and costs. Unfortunately, it may increase costs later on for Mars missions.<br /><br />Finally, there are some tasks that can probably be done in parallel that are currently scheduled in serial, primarily for budget reasons. With a little more money earlier in the program, these tasks could be done concurrently and thus accelerating the schedule with very little impact on the long-term cost of the program. If China or Russia appear that they may reach the Moon before the US, Griffin can propose this shifting of funds to Congress.</i>
