i've been fascinated about rockets since im 3, was drawing engines with turbopumps by 5, but since i read about ecology at 35 i am now convinced we need exactly two types of satellites:

1) earth observation and weather one, to monitor a very dangerous warming on this planet

2) icbm early warning systems, to avoid cooling it very fast.

what argument do you have for more orbital stuff and which type?

[oh_sigh]

Communications and astronomy seem like very reasonable uses of space. Comms because how much of the planet can be seen/covered be a single device, and astronomy to bypass information loss from the atmosphere.

[immmmmm]

agreed! it's important to communicate, and studying distant worlds makes us human (but as a physicist im biased).

maybe an international mission to mars could be useful. dunno.

GPS etc. are pretty important.
