I'll be 77 then, with some luck between now and then. That's a long time for electronics/electromagnetics/computers these days. The constellation will be obsolete before it dies. Which is no bad thing. Dying while in action, like the existing constellation, is annoying. Dying before action is even worse; I have just read the launch fiasco of the dozen destroyed on the Zenit in 1998. The existing constellation has still got to get through to launch of the replacement constellation. It will help to have the spares launched, to plug a few holes, but that will be palliative only. Reaching the end of the constellation life and no satellites ready to go. That's hazardous. If there is a gap of 6 months from when the existing constellation conks out and the new one is ready, a LOT of subscribers will have to change to Iridium or other services. They won't come back in a hurry. The new constellation should have been launched BEFORE the existing one started fizzling, not after. The still-surviving satellites will probably fail about the same time, with service decline as photovoltaics continue to whither, fuel runs low and old age sets in. It will be interesting to see the planned launch dates. Long before 2025, there will be other constellations launched, to enable further upgrades and increased capacity of swarms of people sign up for service. This next constellation will have a cost per minute of about 2c a minute, which is a lot less than the 8c a minute of the previous constellation. That's so cheap that if it's sold in the right way [meaning no stupid, greedy, rip-off telecom prices per minute] nearly everyone could afford it at a retail price of 5c a minute when the system is fully loaded - they should of course be sold for 0c a minute until the system is loaded, with profits coming from handset sales and financing of handset purchases. 10 years later, and off we go again. Maybe this time they'll get it a bit right instead of doing it all wrong. So far, there are some good indications, but plenty of bad ones. Mqurice
