- Lacus Spei was captured on Apollo 16's color-Hasselblad AS16-122-19606. In this frame, the camera was looking west-northwest. Crater Gauss is noticeable in the foreground, while the dark Lacus Spei is seen near the curved horizon. It is worthwile to compare this photograph with LAC-28 in the Clementine Atlas.

Nomenclature
- Lacus Spei is Latin for "Lake of Hope".
- In the original 1935 nomenclature of Blagg and Müller this feature was called "Struve" (the one described by Elger, and presumably named for F. G. W. Struve, the founder of a long line of famous astronomers).
- In the System of Lunar Craters that name ("Struve" without an initial) was moved to the west limb (where it was assigned to a large crater formerly known as "O. Struve"), and the name of the present feature was Latinized to Mare Struve (IAU Transactions XIIB).
- In 1976 the name was changed to Lacus Spei with a note that the feature had formerly been known as Lacus Struve (IAU Transactions XVIB). No record can be found of in the IAU Transactions of the name Lacus Struve ever having been used prior to this. - Jim Mosher
- Was Mare Struve, or Lacus Struve (or Struve) one of Madler's names? (see Appendix I, page 219) in Ewen A. Whitaker's Mapping and Naming the Moon.- DannyCaes Sep 6, 2009
