Surveyor 7 is a lander mission by NASA / JPL on Moon. Landed January 10, 1968. Landing site: Near Tycho crater rim.

Surveyor 7 was the last and most scientifically ambitious of the Surveyor series. Unlike all previous Surveyors that landed on flat mare regions, it targeted the rugged highland terrain near Tycho crater. It carried a surface sampler, alpha-scattering instrument, and camera, discovering that highland soil is chemically different from mare basalt, with higher aluminum content suggesting anorthosite composition.

  • Highland soil differs chemically from mare basalt
  • Higher aluminum content in highlands indicates anorthosite
  • Magnetic material present in lunar soil
  • Only Surveyor mission to land in lunar highlands
  • Most scientifically capable Surveyor mission
  • Combined scoop, camera, and chemical analysis
