Smart Lander for Investigating Moon (SLIM) is a lunar lander being developed by the Japan Aerospace Exploration Agency (JAXA). The lander will demonstrate precision landing technology.[3] As of 2017, the lander is planned to be launched in 2021.[2][4]

Overview[edit]
SLIM is Japan's first major lunar surface mission, and will demonstrate precise, pinpoint lunar landing. During its descent to the Moon, the lander will recognize lunar craters by applying technology from facial recognition systems, and determine its current location from utilizing observation data collected by the SELENE (Kaguya) lunar orbiter mission. SLIM aims to soft land with an error range of 100 m (330 ft).[4][5][6] In comparison, the error range of the Apollo 11 Eagle lunar module was an elliptic which was 20 km (12 mi) wide in downrange and 5 km (3.1 mi) wide in crossrange.[2] According to Yoshifumi Inatani, deputy director general of the JAXA Institute of Space and Astronautical Science (ISAS), by succeeding in this extremely precise landing, it will lead to enhancing the quality of space exploration.[7]
SLIM is planned to be launched together with the XRISM space telescope, and is to land near the Marius Hills Hole,[8] a lunar lava tube entrance discovered by Kaguya.[9] The expected cost for developing this project is 18 billion yen.[10]
Potential rover[edit]
The SLIM team assessed in the past the inclusion of a small rover in this mission. A preliminary concept considered a rover with two inflatable wheels that would enter —or drop into— the lava tube while deploying miniature communication relay devices along the traverse.[11] Other concepts suggested developing a miniature rover without wheels but able to "hop" along.[12][13][14]
History[edit]
The proposal which later came to be known as SLIM existed as early as back in 2005, as the Small Lunar Landing Experiment Satellite (小型月着陸実験衛星).[15] On 27 December 2013, ISAS called for proposals for its next "Competitively-Chosen Medium-Sized Focused Mission", and SLIM was among the seven proposals submitted.[2] In June 2014, SLIM passed the semi-final selection along with the DESTINY technology demonstration mission, and in February 2015 SLIM was ultimately selected.[16] From April 2016, SLIM gained project status within JAXA.[17] In May 2016, Mitsubishi Electric (MELCO) was reportedly awarded the contract for building the spacecraft.[18] SLIM is scheduled to be the second Japanese lunar lander to operate from the Moon's surface; on 27 May 2016 NASA announced that the OMOTENASHI (Outstanding MOon exploration TEchnologies demonstrated by NAno Semi-Hard Impactor) CubeSat lander jointly developed by JAXA and the University of Tokyo will be launched as a secondary payload on Space Launch System Exploration Mission 1. OMOTENASHI will deploy a mini lunar lander weighing 1 kg.[19]
In 2017, because of funding difficulties arising from XARM(XRISM)'s development cost, SLIM's launch was switched from a dedicated Epsilon flight to a rideshare H-IIA flight.[20] The resulting cost savings will be transferred to develop other satellites that are behind schedule due to XARM.[20]
