About Smart Lander for Investigating Moon (SLIM)

Small probe challenges an accurate lunar landing

The SLIM embodies the research of techniques that enable accurate landing and the demonstration of the techniques on the moon. These innovations, if successful, advance JAXA toward capabilities needed for future lunar exploration missions. The same innovations will bring about a paradigm shift. The current approach searches for the site target optimized for landing. The techniques to be acquired will bring the spacecraft down to the desired point, instead.
The downsizing employed in the SLIM mission is unique, opening up the possibility of reaching the navigation accuracy on other planets where spacecraft must enter with tougher payload resource requirements.
Application of the SLIM technology will deliver to Earth lunar sample about the size of Hayabusa encapsulated by a vehicle launched from the moon.
JAXA’s Institute of Space and Astronautical Science is pressing on the SLIM research with researchers from universities and other organizations.

SLIM Mission Objectives

Following are the SLIM mission objectives thereby JAXA endeavors to contribute to future missions to explore the moon and other planets;

  • Demonstration of the accurate lunar landing techniques embodied in a small explorer
  • Acceleration of the study of the moon and other planets using the lighter exploration system

Future solar science exploration will demand the level of navigation accuracy that JAXA is in the quest for through the SLIM mission. As scientific knowledge builds on the study object, more specific research will be needed. Placing spacecraft with precision facilitates the expertise. Planetary science exploration will additionally call for highly capable equipment for observation. Downsizing the exploration system can reinforce the instruments to be placed into a locale especially well suited for its mission of landing.
