Abstract

By acquiring the technique of pinpoint landing to the place where you want to land and demonstrating it on the moon, it enables landing the planet that is more restrictive than the moon and sample return.

Goal

It is the development of a small spacecraft aiming to research the pinpoint landing technique and demonstrate it on the moon.

Objective

1. Demonstration of high accuracy landing technology to the moon, 2.Improvement observation accuracy with lightweight exploration system

Use of the Supercomputer

In the development of the satellite contact part by the lattice composite material structure for the kick stage, it was utilized for the design evaluation analysis and the verification analysis with the test.

Necessity of the Supercomputer

Supercomputer was necessary to obtain analysis results of dozens of cases quickly.

Achievements of the Year

The lattice composite material satellite joint part were conducted strength evaluation before and after the rigidity test and the strength test.The validity of the design was confirmed and the cause of the nonlinear phenomena occurring the test was also clarified.
