The cost of a single RD-6 satellite is $350 million. A MK-8 imaging satellite carries a price tag of $300 million. Another significant factor with satellites is the cost of the launch. In particular, launching a single RD-6 satellite into space is expected to cost the company $100 million. Due to its heavier weight, launching a MK-8 satellite warrants a heavy-lift launch vehicle instead of a medium-lift launch vehicle used in the case of a RD-6 satellite launch. As a result, the cost of a MK-8 satellite launch is estimated to be $185 million. Both satellites are to be depreciated straight line down to a book value of zero over their entire useful life. Further details of each satellite’s cash flows are tabulated below:

	RD-6 satellite	MK-8 satellite
Annual revenue (to be received at the end of the year)	$105 million	$100 million
Annual operating cost (to be paid at the end of the year)	$25 million	$21 million
Satellite life	15 years	20 years

In addition to the cash flow information, you have also been provided with the following details:
 The corporate tax rate is 30%;
 Tax is paid on profits at the end of the year in which it is earned; and,
 The required rate of return for both investment opportunities is 9.8% p.a..
