Public Lecture: The Apollo Missions, the far side of the Moon and continued studies from a distance

Public Lecture hosted by the St. Louis Astronomical Society

Room 162 McDonnell Hall, Washington University in St. Louis

Abstract:  In light of the recent 49th Anniversary of Apollo 11, we will discuss how the Apollo missions reframed our understanding of the Moon and how this research continues with lunar orbiters. Before stepping foot on the Moon, man’s knowledge of our neighbor came from remote sensing. Photometry, or the science of the measurement of light, has been used for about 2,000 years by astronomers. The dark patches on the near side of the Moon were named “mare” or sea based on differences in reflected light.


During the Apollo program we landed six missions on the lunar surface and found an ancient, lifeless world that was genetically related to Earth but with virtually no water. Despite traversing only 60mi (97km) of the Moon’s 2160mi (3475km) diameter, the discoveries made from the Apollo missions greatly enhanced our knowledge of the entire Moon, including the far side. These discoveries led to the “Giant Impact” theory and the Lunar Magma Ocean (LMO) hypothesis.


What about today? Though humanity’s last footprint on another planetary body was 45 years ago, the discoveries from the Apollo missions continue to inform modern lunar research.   Read more... 

Call for Research Papers: Meteoritics & Planetary Science (MAPS) - Special Issue in honor of Dr. Christine Floss

Papers are solicited for a Special Issue of Meteoritics & Planetary Science dedicated to the memory of Dr. Christine Floss and organized around the general theme of “Understanding our solar system history through In-situ micro- and nano-analysis of extraterrestrial materials”.


For over 30 years, Dr. Christine Floss analyzed the isotopic and elemental compositions of macro- to submicroscopic components in extraterrestrial materials using coordinated in-situ ion microprobe (IMS-3f and NanoSIMS 50) and electron microscopy (SEM, Auger Nanoprobe and FIB-TEM) techniques to better understand secondary processes (e.g., thermal metamorphism, aqueous alteration) during the early history of our solar system. Christine worked on a wide range of planetary samples, from meteorites, micrometeorites and interplanetary dust particles to returned samples from NASA Apollo, Stardust and Genesis missions. She was also one of the experts on the identification and characterization of circumstellar and protosolar components in these materials, in particular presolar silicate grains, to investigate their abundances and origins.



Manuscripts that focus on current and critical issues related to Christine’s broad research interest will be considered for this Special Issue. 

The review process of manuscripts for this Special Issue will be overseen by MAPS chief-editor A J Timothy Jull, MAPS Associate Editor Alexander Ruzicka, and guest editor Larry Nittler. All manuscripts will undergo the normal MAPS review processes.


Special Issue Proposers: Pierre Haenecour and Maitrayee Bose.



Deadline for submission: December 31, 2018 



All the guidelines for manuscript preparation and submission are posted on:

In Step-6 of the submission process, please select “Christine Floss issue” in the Special Issue section.
