To achieve this objective there is a need for a geospatial information system (GIS) to provide lunar scientists, engineers, mission formulation teams, and mission operations teams with a broad range of quantitative analysis and visualization tools to support critical mission-related decision-making processes.

Most lunar scientists will acknowledge that transient events such as outgassing and impact cratering do occur over geologic time: the controversy lies in the frequency of such events.

Thus, after a long trouble-plagued start that taught the system engineers a great deal and the scientists very little, Project Ranger finished with three flights that greatly advanced the lunar scientists' knowledge of the surface and served to whet their appetites for a closer look.

However, standard usage among lunar scientists is to ignore that distinction.

Graham Ryder (28 January 1949 - 5 January 2002) was an English geologist and lunar scientist.

The NLSI brings together leading lunar scientists from around the world to further NASA lunar science and exploration.

These theories are orthodox in the sense that they are believed by most lunar scientists.

Paul D. Spudis (born 1952) is an American geologist and lunar scientist.
