月惑星科学会議（LPSC）：アポロの遺産と月科学

Standing by for Apollo legacy session. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

Lunar origin by Giant Impact (Canup): based on the idea on isotopic similarity and diffrence with Earth and the Moon, she discuss the requirement for the next step to clarify the details of the Giant Impact. #LPSC2019

The Lunar Magma Ocean is Dead,;Long Live the Lunar Magma Ocean! (Elardo): lunar "magma ocean" understanding need to consider many constraints. ~4.35Gy is the important age shows global magma ocean event. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

The Lunar Apollo Missions: Enabling Dating of Planetary Surfaces Throughout the Solar System (Hiesinger): So, so many co-authors whose name cannot be fit in one slide!! #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

More sample is needed to determine surface age based on crater density (crater chronology). Also, it is closely related to identify age of major lunar volcanic activities. Maybe sampling from the far side of the moon help this. (My feeling) #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

A Glint of Light on Broken Glass: Solar System Bombardment History (Barbara Cohen): Legacy of the Apollo sample is the link forged between radiometric ages and relative ages of crater counting. Definitely, time axis is really important. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

Barbara attempts sample-based approach for determining ages of ancient lunar activities. Apollo legacy is living, but we need to go beyond the Apollo, more sampling! (My opinion) #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

The best part of the pie - the crust (Gross): showing sketch by Galileo in 1610 and LRO data (maybe) in 2016. Lunar crust is an archive that needs to be studied. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

Lunar meteorites are very important source to tell us primitive history of the Moon, as well as Apollo samples. Lunar crust is the best source to know the new information on the Moon. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

An Apollo Legacy: Samples, the Gift that Keeps on Giving to Future Generations (Shearer): we have still a "new" Apollo samples after 50 years ... Reevaluation, hidden samples and some special samples. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

We have still the possibility to find new knowledge from the existing Apollo samples, We will bridge the research to the next generation by combining currently available samples; meteorites and preserved Apollo samples. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

Geophysics and Shallow Internal Structure of the Moon (Zuber): from this lecture, we will switch from geochemical and material-based apporoach to geophysical one. She is a principal investigator of #GRAIL mission. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

Geophysical (mainly by #GRAIL ) data and sample-derived data has very good consistency. "Gravitationally, no terrestrial planet resembles the Moon" #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

The Moon's Deep Interior (Weber): Seismic approach and geophysical investigation (mainly by satellite) can combine to understand structure of deeper moon interior. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

I have been involved in moonquake study in my graduate student days. I really noticed data quality of moonquake acquired by Apollo is very low. In this context, we need to hand over Apollo legacy to the NG with more precise, sensitive moonquake observation. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

Global Composition of the Moon (Carle Pieters): Kaguya & M3 revealed that PAN (Pure Anorthosite) is distributed globally. Low-Ca pyroxene dominates highland megaregolith. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

From remote observation,PAN, Mg-rich pyroxene, Olivine & Mg-spinel is all global but varies in their occurence. To fill the piece, "To be continued". #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

Endogeneous Lunar Volatiles (McCubbin): in Post-Apollo view of lunar water, no hydrous minerals, no evidence of aqueous alteration, ingineous lunar water was not definitely detected. Such depletion of volatiles has been attributed to Giant Impact. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

Magmatic volatiles are present in lunar magmas. changed former viewpoint. Also, some water-bearing minerals, such as Apatite, found in lunar samples. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

The Lunar Regolith as Understood from Near and Far (Denevi): regolith is formed during impact, distributed thick on the moon. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

Important Mysteries: Farside regolith/megaregolith, properties of polar regolith, volatile migration through regolith, space weathering & lunar swirls. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

Ten Years of LRO (Petro): @LRO_NASA the concept of LRO goes back to 1972, just after Apollo landing. LRO realized it with very modern manner. #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

Currently, LRO's 4th Extended Mission Proposal is in, with more 3 yrs. "4th series is always exciting" like Star Trek & Star Wars ... ? #LPSC2019

Junya Terazono 寺薗淳也 @terakinizers

As of January 2019, LRO has approx 20kg fuel, sufficient to continue for more 7 yrs in orbit. LRO is now linked with NASA's future lunar mission CLPS. Already LRO produced over 1 PB (PETABYTE) data at PDS. 3 more yrs of giant leaps. #LPSC2019
