We all know that new technology will likely be used as we humans begin to travel through space. No exploration crew from our planet will leave without some form of nanotechnology. Exploration crews will surely benefit from this tech that could potentially be used in numerous places. While nanotech will surely be used for a lot of major things, there is a possibility that it could become problematic. This might affect just the crew of a specific ship, but it might also affect other exploratory vessels from our planet too. Moreover, we could potentially cause problems with other celestial bodies. There is also no telling how our nanotech could be used with things like alien technology.
