Images & 3-D Movie around Marius Hill by TC & MI
Updated : 2009.11.02
Observation date :

Images of a possible 65 m diameter lunar lava tube skylight in the Marius Hills taken by SELENE Terrain Camera (TC) and Multi-band Imager (MI).

(Upper left figure) Overview of the region from (TC, 20 May 2008; 12.9 to 14.4 degrees north latitude and 55.7 to 57 degrees west longitude, and is 35 x 45 km in size).
(Upper right figure) A hole (Marius Hills Hole; MHH) at 303.3°E, 14.2°N in a rille (Rille A). (Lower four figures) Enlarged TC and MI images of MHH (first and second figures from the left are TC images from 20 May 2008 and 21 January 2009; third and fourth are MI images from 17 March 2009 and 13 April 2009). Arrows indicate the directions of solar illumination (I) and the view vector from the camera (V).
The depth of MHH has been estimated to be 80 to 88. If there exists a lava tube under MHH, its maximum width can be wider than a few hundred meters.

A 3-D movies around Marius Hill by TC are available from the followings.

The area shown in the movie is same as the upper left figure (12.9 to 14.4 degrees north latitude and 55.7 to 57 degrees west longitude, and is 35 x 45 km in size). The left edge is south in its beginning of the movie.
First, we directly approach the Marius Hills Hole (MHH) and circle above it. Then, we fly away from the MHH along a rille (Rille A) towards the east. Next, we change course to the north and fly over the volcanic crater from which lavas flowed to form the rilles. After looking at the northern rille (Rille B), we cross a hilly region that contains lots of volcanic domes. This area, the Marius Hills, was one of the most volcanologically active regions of the Moon. Finally, we head back toward the MHH.

The data was processed by the LISM/TC team.
