nasa is not a brand, nasa is the abbreviation of NASA.

NASA is an administrative research agency of the U.S. federal government, responsible for formulating and implementing the U.S. space program and conducting research on aeronautics and space science. NASA is the world's most authoritative aerospace research institution. It shares its research data with many domestic and international scientific research institutions.

Many clothes have the NASA logo on them because they are brand clothes co-branded with NASA. After some brands apply for NASA trademark authorization, they can launch some products containing NASA elements and trademarks. Authorizing co-branding is very simple. You only need to report the clothing pattern to NASA.

NASA’s research fields are as follows:

1. Aeronautical research and exploration

Including space science (solar system exploration, Mars exploration, lunar exploration , Universe structure and environment), earth science research (Earth systems, earth science applications), biophysical research, aeronautics (aviation technology), and undertake certain training plans.

2. Aviation technology

Aerodynamics (turbulence, airfoils, supersonic flight), propulsion technology (combustion and fuel, noise and its propagation, computational fluid dynamics, turbine Mechanical component research), materials and structures (composites, high-temperature materials, dynamic loading and aeroelasticity, structural analysis), avionics and human engineering (navigation, avionics, flight management and simulation technology).
