[IGPP Everyone] [EPSS Everyone] Special Seminar, J. Haruyama (JAXA), Wednesday at 4 pm

[David Paige]

Hi Everyone, J. Haruyama of JAXA, the Japanese space agency, will be 
giving a special seminar TOMORROW at 4 pm in 3853 Slichter Hall:

Title:

UZUME project: A Japanese exploration project to lunar/Mars Caves.

Speaker:

Junichi Haruyama, Ph.D.
(JAXA: Japan Aerospace Exploration Agency/ISAS:Institute of Space and 
Astronautical Science）

Abstract:

  In 2009, three vertical holes of aperture diameters and depths of
several tens of meters to one hundred meters were discovered in the
lunar Marius Hills, Mare Tranquillitatis, and Mare Ingenii in the
Terrain Camera (TC) and Multi-band Imager (MI) aboard Selenological and
ENgineering Explore (SELENE, nicknamed KAGUYA) of Japan.Similar hole
structures have been identified at the foot of Tharsis Montes and
Elysium Mons on Mars.The lunar holes were later imaged by the United
States Lunar Reconnaissance Orbiter (LRO) Narrow Angle Camera (NAC) 4)
of better resolution 0.5 to 2 m/pixel than SELENE TC and MI. The floors
of the holes in the images taken by LRO-NAC were apparently not bawl
shapes, different from the inside floor shapes of normal craters.
Furthermore, the LRO carried out oblique observations and provided
images of cavern spaces expanding from the floors of the vertical holes.
Furthermore, recent works based on GRAIL gravity data (Chappaz et al.)
and SELENE Lunar Radar Sounder data (Kaku et al.) suggest the existence
of long caverns, perhaps intact lava tubes, under the subsurface of the
Moon. Since the last year 2016, we have started considering projects
which will directly explore the lunar and Martian caverns through their
skylight holes. We name the project as UZUME. In this presentation, I
would introduce the UZUME project.

For those interested, there will be a dinner in Westwood after the seminar.
