text:  It's actually in terms of it is cheaper because we can get multiple satellites on the same mission, and also very much in terms of precision. Again, I'll refer to Ariane 5 that launched the James Webb telescope in Christmas a couple of years ago, and it did such a good injection precision of the injection that the life of the satellite was extended from a predicted 10 years to 20 years. So when you're getting a satellite in exactly the right orbit, then it uses much less of its own propellant, so it can actually survive longer in orbit and operate for a longer time.
