NASA drafted a 20yr+ roadmap for the development of nanotechnology and injected the relatednanotechnologies into its launch missions. Those nanotechnologies are considered to enable a precise control of desiredmaterial properties, and after being fully utilized, could lead to the manufacture of smaller spacecrafts with betterenvironmental applicability in the future. This paper follows the important projects concerned, include: 1) Advancedstructural materials and their applications; 2) Energy generation and storage; 3) Thermal control materials and theirapplications; 4) Sensors, electronics and devices; 5) New patterns of propellant and propulsion.
