Apollo 17 ANGSA Workshop
October 26–28, 2022
Houston, Texas


The 50th anniversary of the Apollo 17 mission is in December 2022. By every metric, this mission to the Taurus-Littrow Valley (TLV) was the most accomplished of any of the Apollo missions to the Moon, leading to 50 years of extensive, continuing analytical investigations of its observations, samples, photography, and geophysical data. Using mobility offered by the lunar rover, 35.7 kilometers were traversed during three excursions (aka extravehicular activities or EVAs) of greater than 7 hours each. Active seismic, gravity, and electrical property data added three-dimensional context. During the EVAs, over 110 kilograms of rock and regolith samples were collected, and years of detailed analyses have placed them within the geologic context of the TLV locally and the Moon as a whole. These samples include a deep drill core nearly 3 meters in length and three double (70 centimeters) and two single (35 centimeters) drive tube cores that contain records of the history of both the Moon and the Sun. The double drive tube from Station 3 was never examined until recently, and the lower section of the core was sealed in a core sample vacuum container (CSVC). This drive tube and frozen samples collected from shadowed areas and the deep drill core are targets for the Apollo Next Generation Sample Analysis (ANGSA) initiative.

The Apollo 17 surface activities, capabilities, training, crew makeup, and operations are an invaluable baseline for future human endeavors on the Moon’s surface during Artemis missions. New analyses of Apollo 17 samples enabled by ANGSA, NASA’s research and analysis funding programs, independent synthesis, and recent orbital and landed missions (e.g., LRO, LADEE, GRAIL, LCROSS, SELENE, Chandraynaan-1, and Chang’e missions) have fundamentally changed many of our concepts for the geology of the TLV as well as the Moon. The goals of this workshop include:

  • Revisiting the TLV by integrating new geologic and exploration context, new ANGSA sample data, orbital observations, and the full breadth of data sets from all six Apollo landed missions for a fuller understanding of the Moon, the Sun, and the Earth.
  • Establishing links among multiple generations of lunar scientists and engineers as we prepare for our future on the Moon.
  • Focusing on scientific and design lessons learned from both Apollo and from ANGSA in preparation for near-term human exploration of the Moon.

Topics, Purpose, and Scope

  • New Apollo 17 sample and ANGSA results
  • Lunar volatiles
  • Magmatic evolution and volcanic, tectonic, and cratering history as informed by remote sensing studies and laboratory analyses of samples from the TLV
  • Solar and terrestrial history
  • Triggers and dynamics of lunar landslides and features of their deposits
  • Nature of lunar basin massifs
  • Nature of the lower crust and mantle
  • Paleointensity and orientation of the global magnetic field
  • Collecting-preservation-curating-analyzing lunar volatiles
  • Future Apollo 17 collaborative studies preparing for the future of lunar exploration
  • Examining the potential of pre- and post-cursor robotic missions.


The workshop will consist of invited and contributed presentations plus breakout groups focused on specific topics, with short reports expected from the breakout groups and presented during the workshop. Presentations and results of the workshop will form the basis of a special issue in a peer-reviewed journal. Manuscripts for this special issue will be due within three months after the workshop.

To be added to the mailing list to receive pertinent information about this workshop, submit an Indication of Interest.
