It heavily depends on the cost of the asset. If a satellite costs close to 1bn, it worth to use $110/launch but more reliable rocket.
- hackuser 11y agoTrue. Also don't forget the opportunity cost of the time lost: 1) building a replacement and waiting for a spare slot in which to launch it, 2) engineering, manufacturing, and other resources which could have been used for (and likely were planned for) something else, but now are used for the replacement, and 3) the project the asset was used for, and its output (revenue, research results, etc.), now put on hold. Many organizations don't have the spare time and capacity to afford all of that; they or their project may simply be done.
- fbender 11y agoKeep in mind that several copies of a satellite will be built during production. Some are mockups of a few subsystems (e.g. structure), some are used for tests (e.g. thermal, electrical, interference), often there's also a "flight spare" which is an exact copy of the satellite in case something goes wrong with the flight hardware (e.g. broken during testing, launch failure). E.g. Curiosity has such a spare (I'm not sure if it's the same as the flight hardware or close enough) which will be sent in a future mission (I think 2017, though I don't have any sources at hand) with (some) different experiments on board.
- damoncali 11y agoFor some context, that's roughly the cost of a single instrument for the Hubble (~$100M). There's no free lunch in the space business...
- jimrandomh 11y agoBut do realize that the replacement cost of an instrument is much lower than the original creation cost; most of the cost of these things is designing and tooling, and not part of the unit cost of the actual article.
- solomatov 11y agoThere're much more expensive satellites. See, for example, http://www.space.com/11606-rocket-launches-missile-defense-satellite-geo-1-sbirs.html http://www.space.com/11606-rocket-launches-missile-defense-s...
- 27182818284 11y agoAnd if I recall, some of the SpaceX launches are pricier (though not that level) for the more sensitive payloads--as in there is a Secret-Spy-Satellite optional charge package.
- greglindahl 11y agoThe extra charge is due to the paperwork requirement for these launches... which were imposed after a series of launch failures by LM and Boeing rockets carrying very expensive US Government satellites.
- will_hughes 11y agoAnd the paperwork is (in part) because the US Government doesn't purchase insurance on their launches.
