National Aeronautics and Space Administration

NASA is the federal agency responsible for civilian space exploration, aeronautics research, and the science missions that study Earth, the solar system, and the universe beyond it. Created in the late 1950s as an independent executive agency, it sits outside the cabinet departments but answers to the president and Congress, which sets its budget and priorities each year.

Human spaceflight remains one of NASA’s most visible roles, spanning astronaut training, crewed missions, and long-term goals like sustained presence on the Moon and eventual travel to Mars. Coordinating multiple crews and vehicles at once is a genuine logistical and technical challenge, one that stretches the agency’s launch infrastructure and ground teams.

Partnerships with private industry now shape much of how NASA gets to space. Rather than designing and building every rocket and capsule itself, the agency increasingly buys transportation and services from commercial companies, a shift that has changed how missions are funded, planned, and carried out.

Science and research make up the rest of NASA’s mandate, including satellites that monitor climate and weather, telescopes that probe deep space, and aeronautics work that feeds into the broader aviation system. These programs compete for funding alongside human spaceflight, and debates over how to balance exploration, science, and commercial partnerships are a recurring feature of the agency’s politics.
