View Full Version : RapidScat on the big expensive thing

Much has been made about how Dragon CRS-4 delivered the RapidScat (seriously, noone saw the flaw in that name?) instrument to ISS and so now the station will be doing a bit of a Skylab by being an advanced meteorological observation post.

So what are the benefits of putting it on ISS rather than just launching a satellite? ISS in particular gets much criticism for being an expensive political project that isn't worth the huge amount of cash sunk into it and everything it does could be done by robots better. Does RapidScat serve to help justify the orbital outpost?

The main 2 benefits are COST and SCHEDULE. This method allows for a much cheaper and more rapid deployment of a world-class scientific instrument.

So it's good to have a platform already there on which to mount instruments rather than each needing to be self contained with their own propulsion, power, communications etc. But does that platform need to be manned?

I suppose it didn't *have* to be an inherent requirement, but there are no other platforms available that can be supplied and can have an instrument installed. I suggest researching the history of the RapidScat intstrument and how it all came to be.

Nice to be able to fix it, or replace it. I miss ENVISAT.
