“…Hara et al reported a landing method that used a momentum-exchange impact damper (MEID). [4][5][6][7][8][9][10] This method realizes a soft landing by controlling the momentum of a spacecraft by launching damper masses. To increase the momentum exchange efficiency, Kushida et al proposed an active/passive hybrid MEID (HMEID), 7) which uses both active and passive elements for the mass launch.…”

“…We focus on the rebound suppression performance, as in the previous work. 9,11) In addition, this work also focuses on the acceleration suppression performance as a more detailed evaluation. This paper reveals the effectiveness of the BESM in comparison with the G-HMEID and discusses its robustness against variations in some of the parameters such as the ground stiffness, ground damping, base mass, installed mass, and separation timing.…”

In future surveys, planetary exploration spacecraft will need to land on rock beds and slopes. Therefore, spacecraft should be equipped with landing methods to facilitate soft landings in these severe regions. However, conventional landing methods have problems such as high rebound, the impossibility of reuse, and excessive resource consumption. To overcome these problems, the authors previously invented several landing methods, but these have practical limitations. Thus, this paper proposes a novel landing mechanism called the base-extension separation mechanism (BESM), which focuses on energy conversion using springs and separable units, and discusses a single-axis falling-type small-scale model of a spacecraft with the BESM. Then, the rebound and acceleration suppression performance is evaluated through simulations. These reveal that the BESM realizes good performance under nominal conditions. The BESM is shown to have good robustness against variations in the ground stiffness, ground damping, spacecraft mass, and installed mass. The study findings reveal that the BESM is a promising method: it overcomes the drawbacks of the conventional methods and our previous inventions. In addition, the BESM generally performs better in soft landings than our previous inventions.

“…Until now, the effectiveness of MEIDs has been demonstrated with simulations and experiments based on a single axis (SA) [5][6][7][8], and the effectiveness of MEIDs in a double-axis scenario has been verified only for AMEID systems [4]. However, actuators increase the overall mass of the system, and may lead to control errors.…”
