Are you kidding?
Eagle costs millions for us to launch P4 lite is FREE?
Phase 4 will have 400 watts of power given to us for FREE for 15 years.
Phase 4 will have engine and fuel and ground control station keeping
in a geo sat position for FREE for 15 years.
All we need to do is build the transponder and enjoy the free ride
... and not to even go begging to find a ride.
Phase 4 to me should have absolute priority over Eagle, at least for
the first P4 (I assume there may be more in the future?).
