| Such a microsatellite has to be placed in a libration point between the Sun and the Earth. |
| Accuracy of libration angles depending on accuracy of measuring selenographic coordinates is estimated. |
| Its space segment will be composed of a group of X-ray telescopes based around one of the libration points or Lagrangian points. |
| The one on the left illustrates the manner in which the libration in longitude is made apparent. |
| To see how a global ocean could affect libration, take two bottles, fill one with sand and the other with water, then spin them. |
| Spacecraft located near the L1 libration point provide data on several characteristics of the solar wind. |
