Carbon nanotubes, which are cylindrical forms of carbon molecules,  assist NASA and other space companies in saving money by miniaturizing the size of instruments, without sacrificing its abilities. Additionally, because NASA generates their own power source for their missions, it is in their best interest to make wise decisions about where they are spending money. Luckily, nanotechnology can be used to develop architectures, devices, materials, and systems at the nanoscale level to produce  lightweight and often times tiny products.
