The Surveyor 1 spacecraft, its operation, and findings are briefly described. Data were obtained on the topography, photometric and colorimetric properties, temperature, radar cross section, and mechanical properties of the lunar surface. The mare surface around the landing site consists of separate, somewhat cohesive, particles. The bulk of the particles are smaller than 1 mm (0.04 in.), but the particle size distribution extends up to 1-meter (3 ft) blocks or larger. The surface bearing resistance is about 5 × 105 dynes/cm² (7 psi). The solar corona was photographed from the moon. Plans for future Surveyor flights are outlined.
