Geological investigations can be performed from orbit or at the surface of a planet. On Earth, field geologists often perform investigations with science instruments that take hours to days in order to understand subsurface processes and find buried features of interest. Astronauts and rovers will one day carry out similar investigations on other planetary surfaces. Dr. Richardson studies how astronauts and robots can best deploy geophysics instruments to look for important resources and geologic units below the surface.
Volcanism is a major geologic process on rocky and icy planets that paves new surfaces with lava flows, modifies the crusts of planets with magma intrusions, and delivers gasses and particles from deep within a planet its atmosphere. Volcanism on Earth and planetary bodies we might one day explore is also a hazard to communities near volcanoes and global air traffic. Dr. Richardson studies volcanic fields and lava flows on Earth and its neighbors to understand the cadence and magnitude of volcanism over geologic time.
Planetary Geology
In preparation for crewed missions to planetary surfaces--starting with the Moon and leading to Mars and beyond--new scientific measurements are needed to improve mission outcomes. What scientific research can be performed on the lunar surface, what research requires samples to be returned to Earth by Artemis crews, and how we can safely and expediently explore a landing site in early Artemis missions are critical decisions that NASA is now tasked with making. Researcher participants of Goddard Space Flight Center's Applied Lunar Science Group work in service of NASA's needs to advance urgent science and exploration goals for the Moon and provide foresight towards martian exploration.
Currently, Dr. Richardson serves as the Deputy Lead of the Applied Lunar Science Group.
Geophysics
GEODES (Geophysical Exploration of the Dynamics and Evolution of the Solar System) is a team within the NASA Solar System Exploration Research Virtual Institute, or SSERVI. GEODES scientists investigate the Moon, near-Earth asteroids, and the moons of Mars with geophysics methods to enable the exploration of their surfaces. Dr. Richardson serves as the Deputy Principal Investigator of GEODES and leads the Magma-Tectonics Theme, which investigates lunar lava flows and magmatic bodies as well as tectonic features on the Moon and Phobos. Magma-tectonic features can mobilize or trap volatiles and ore materials. Also, the ability for faults to become active on the Moon or other airless bodies is important to understand before humans are sent to explore their surfaces. Learn more at geodes.umd.edu.
Planetary Geology
As a lead of the Goddard Instrument Field Team (GIFT), Dr. Richardson directs and performs planetary analog research at field sites on Earth to understand similar processes and features found on other planetary bodies. Dr. Richardson's GIFT research has taken place in Iceland, Hawaii, Alaska, California, Arizona, and New Mexico, where volcanism has modified the surface over geologic time with lava flows and explosive eruptions of ash. Data collected by Richardson and colleagues are geophysical data; analysis of these data add to our understanding of the physical nature of the geologic materials in the subsurface.
Currently, Dr. Richardson studies how to detect persistent ice buried under volcanic ash in preparation for similar investigations on the Moon and Mars. He also investigates how lava flows are emplaced and how lava source vents are constructed during volcanic eruptions similar to eruptions found on Mars, Venus, and the Moon.
Mars
This project seeks to use newly abundant high-resolution data to search for evidence of explosive volcanism to evaluate claims of calderas in Arabia Terra. A systematic survey of Arabia Terra with orbital images and spectrometry is identifying locations where layers of altered minerals might have initially been deposited during volcanic supereruptions in Mars's ancient past.
Extrasolar planets
Extrasolar planets have been detected that likely have rocky surfaces that are subjected to very hot temperatures and enormous amounts of tidal stress as they orbit their star. High stresses and temperatures are known to cause volcanism in our Solar System and so volcanism is almost certainly a common process throughout the Milky Way. Dr. Richardson is a member of a team that is modeling flood volcanism (large lava flows that emit volcanic gas) on exoplanets to understand how detectable "exovolcanism" is from Earth.

Using publicly available data and models of other planets, Dr. Richardson has developed several 3D models of planetary surfaces and crusts, including the landing sites of the Apollo missions. These models can be printed with a 3D printer and downloadable STL format files are found at jacobrichardson.github.io. The Solar System Exploration Division at Goddard Space Flight Center uses these 3D models during public engagement events to show the surfaces and interiors of the Moon and Mars.
