It is not a dumb question, but it is not a particularly useful analogy.
There is a massive difference in technological requirements between sending out a spacecraft, manned or unmanned, and the kind of atmospheric engineering you are talking about. One, rocket flight, is essentially ballistics, and extension and development of a science we have known about for centuries.
The size, chaotic nature and complex interractions of the climate are staggering.
We are only just beginning to develop the technology required to map, track , & properly model the climate, with the development of computers powerful enough and software sophisticated enough to do justice to the climate.
To actively manage the climate, to manipulate temperature, humidity, cloud cover wind, wind speed etc at a localised level - to switch rain on in one area whilst at the same time making sure we are not causing a draught in another part of the globe, or a megastorm somewhere else is quantitatively beyond our technology right now, and a very good thing too.
