Lava-tube on the Moon and exploration to it (Student Organized Event)

Summary
This seminar will include three parts. The first one is Dr. Junichi Haruyama's presentation about lava tube and his related research. He will introduce the method that his research team utilized during period of searching. Some properties of lava tube will be exposed. In the second part, GLT2 team B would like to present their contributing to moon base development with "Nuclear battery based power supply system for future lunar explorations". Final part is our discussion panel discussion.

Abstract
In this lecture, I would introduce recent research results for lunar lava tube and our exploration plan to them. We are aiming to return to the Moon to establish habitable bases on the Moon. However, the surface of the Moon is harsh environment: fatal radiation showers, wide temperature oscillation, and continuous micrometeorite bombardments and so on. On the contrary, subsurface void space such as lava tube where humans and instruments will be protected from the harsh lunar environment seems one of the best candidates to establish lunar base in it. In addition to the potential habitability, lava tube is a treasure cave for science stocking many clues to solve lunar and planetary science issues. Since the discovery of a skylight hole on the Marius Hills on the Moon in 2009, nearly ten possible skylight holes have been found in the images of SELENE (Kaguya) Terrain Camera and LRO Narrow Angle Camera. However, it was difficult to say that each hole apparently connects to a large and long lava tube. Recently Kaku et al. (2018) investigated patterns of radar echo acquired by Lunar Radar Sounder onboard SELENE (Kaguya) and found a pattern at the Marius Hills suggesting existence of intact lava tubes. A possible lava tube was estimated its length to be 50km. We are now planning lunar lava tube through its skylight hole. The exploration was named "Unprecedented Zipangu Underworld of the Moon Exploration (UZUME)".

Introduced
Dr. Junichi Haruyama is the moon and planetary scientist. He has participated in various space studies, for example, Hayabusa, SELENE (Kaguya), Hyabusa2, and so on. Especially, in SELENE project, he is the chief-principal investigator (PI) of Terrain Camera, Co-PI of the multiband imager and the spectral profiler. In Unprecedented Zipangu Underworld of the Moon Exploration (UZUME) project, he is in charge of important positions. In addition, he participated in international lunar and planetary mission. He was selected as the Associate editor of Journal of Geophysical Research (JGR) Planets from 2009 to 2011.
