I'm sure they figured this out and decided against it, but I never understood why they often only send 1 device on missions like these. I understand launching things is very expensive, but you'd figure the R&D and risk associated with failure would cost much more.
- Monotoko 12y agoAye, most of the work is already done. I'm sure a second one could be launched at a fraction of the cost.
- danielweber 12y agoIt's hard to wow the governments with "we are going to do the same thing again, much cheaper." Even though it's the good way to get the most science bang for buck.
