The National Aeronautics and Space Administration’s planned launch Monday of a towering rocket and spacecraft is a test of the agency’s effort to return to missions it pulled off decades ago: landing astronauts on the moon. 

The uncrewed launch would mark a milestone after years of work and setbacks by the space agency and aerospace contractors hired to develop vehicles and related hardware. It would also serve as a starting point for the Artemis program, NASA’s renewed effort to put astronauts back on the moon for the first time since 1972. The agency has said it wants to send the first woman and person of color to the lunar surface in 2025 and establish a long-term presence there.
