This has been an exciting decade for lunar exploration, but it hasn’t been without its setbacks. NASA officials announced a revised schedule for the Artemis lunar program. The subsequent missions are expected to be delayed by approximately one year each, reflecting the extensive work required before astronauts can undertake lunar missions in the latter part of this decade.

The successful Mars InSight mission employed a NASA/European Space Agency robotic lander designed to study the interior of Mars. The mission recently ended with last contact as its dust-choked solar panels failed to deliver enough electricity to keep InSight going. InSight had two science goals: Seek to determine the interior structure and composition of Mars and to reveal how a rocky planet forms, and to study the rate of Martian tectonic activity and meteorite impacts.

Human exploration of the Earth and our universe is pushing ever-expanding boundaries. Along with renewed exploration of the moon and ongoing exploration of Mars, we have also probed the outer reaches of the solar system, and beyond. Beginning in 1972, NASA has executed many successful missions to the outer solar system that have exponentially increased our knowledge of Jupiter, Saturn, Uranus, Neptune, Pluto and their myriad of intriguing moons, such as Pioneer 10 and 11, Voyager 1 and 2, Galileo, Cassini, New Horizons and Juno. These missions have also kindled questions that we did not even know to ask a few decades ago.

In December 1972, geoscientist Harrison Schmitt traveled more than a quarter-million miles, dropped 8.7 nautical miles out of lunar orbit and took a stroll on the moon. That was 50 years ago, and today, with Artemis, NASA envisions a multistage program to return humans to the moon and eventually create a sustainable manned lunar habitat. In Greek mythology, Artemis was a moon goddess and twin sister of Apollo. The Artemis I Space Launch System rocket launched on Nov. 16.

A 15-kilometer-wide asteroid hit the planet 66 million years ago, ending the Cretaceous Period. It wiped out 99 percent of all life and 75 percent of all species of life on Earth. If we were to discover another such a threat coming from space today, what could we do about it? NASA's Double Asteroid Redirection Test launched Nov. 24, 2021 from Vandenberg Space Force Base in California. The DART spacecraft was built and is operated by the Johns Hopkins Applied Physics Laboratory under NASA’s Planetary Defense Coordination Office.

This debate began decades ago: How much of the planet's natural gas is abiotic – made up of methane with nonbiological origins? At times, the scientific back-and-forth argument has resembled a slow-motion tennis match, with a new volley coming every few years. Now, Daniel Xia thinks he has helped deliver a winning smash across the net. His findings were most clearly laid out in a recent article “Validity of geochemical signatures of abiotic hydrocarbon gases on Earth,” by Xia and coauthor Yongli Gao, published in the Journal of the Geological Society.

NASA’s Perseverance rover is currently exploring the delta front of Jezero Crater on Mars. It has traveled 7.4 miles and drilled twelve core samples. For Katie Stack Morgan, geologist and deputy project scientist for the Perseverance Mars rover, the first close-up image of layered rocks at the base of Jezero Crater’s ancient river delta grabbed her imagination. “These are the layered rocks that we came for!” she said.

We are proud of the accomplishments and science achieved with the exploration of the moon by Apollo crews culminating in 1972 with Apollo 17, 50 years ago. No time since has offered so much promise for crews to return to explore the moon and deep space. There are signs of hope that that’s about to change, though.

NASA’s Perseverance rover successfully landed on Mars on Feb. 18, 2021, which AAPG celebrated with a live watch party. Perseverance has since explored the Séítah region and is currently at the delta front of Jezero Crater on Mars using an enhanced autonomous navigation system and under guidance from NASA/JPL controllers. As of May 13, 2022, Sol 436, Perseverance has traveled 11.4 kilometers and drilled eight core samples. The rover has returned more than 249,000 raw images that are publicly available in the mission multimedia catalog.

VG Abstract

The Betic hinterland, in the westernmost Mediterranean, constitutes a unique example of a stack of metamorphic units. Using a three-dimensional model for the crustal structure of the Betics-Rif area this talk will address the role of crustal flow simultaneously to upper-crustal low-angle faulting in the origin and evolution of the topography.

Climate change is not only happening in the atmosphere but also in the anthroposphere; in some ways the former could drive or exacerbate the latter, with extreme weather excursions and extreme excursions from societal norms occurring all over the earth. Accomplishing geoscience for a common goal – whether that is for successful business activities, resource assessment for public planning, mitigating the impacts of geological hazards, or for the sheer love of furthering knowledge and understanding – can and should be done by a workforce that is equitably developed and supported. Difficulty arises when the value of institutional programs to increase equity and diversity is not realized.

In comparison with the known boundary conditions that promote salt deformation and flow in sedimentary basins, the processes involved with the mobilization of clay-rich detrital sediments are far less well established. This talk will use seismic examples in different tectonic settings to document the variety of shale geometries that can be formed under brittle and ductile deformations.

The Energy sector is a changing business environment. Throughout the 20th century fluctuations of oil supply and demand produced changes in the barrel price that pushed the growth or shrinkage of the industry. In this 21st century, new challenges such as diversification of the energy mix, boosting gas demand, require the exploration of critical minerals and development of new technologies as well.

The carbonate sequences that were deposited in the now exhumed Tethyan Ocean influence many aspects of our lives today, either by supplying the energy that warms our homes and the fuel that powers our cars or providing the stunning landscapes for both winter and summer vacations. They also represent some of the most intensely studied rock formations in the world and have provided geoscientists with a fascinating insight into the turbulent nature of 250 Million years of Earth’s history. By combining studies from the full range of geoscience disciplines this presentation will trace the development of these carbonate sequences from their initial formation on the margins of large ancient continental masses to their present day locations in and around the Greater Mediterranean and Near East region. The first order control on growth patterns and carbonate platform development by the regional plate-tectonic setting, underlying basin architecture and fluctuations in sea level will be illustrated. The organisms that contribute to sequence development will be revealed to be treasure troves of forensic information. Finally, these rock sequences will be shown to contain all the ingredients necessary to form and retain hydrocarbons and the manner in which major post-depositional tectonic events led to the formation of some of the largest hydrocarbon accumulations in the world will be demonstrated.

DL Abstract

Paleozoic North America has experienced multiple mountain building events, from Ordovician to Permian, on all margins of the continent. These have had a profound effect on the resulting complex basins and their associated petroleum systems. Subsequent uplift, erosion and overprinting of these ancient systems impedes the direct observation of their tectonic history. However, the basin sedimentary records are more complete, and provide additional insights into the timing and style of the mountain building events. In this study, we employ ~90 1D basin models, ~30 inverse flexural models, isopachs, and paleogeographic maps to better understand the Paleozoic history of North America.

DL Abstract

For well over a century there have been conflicting indications of the strength of the crust and of faults and what controls them.  Much of our ignorance comes quite naturally from the general inaccessibility of the crust to measurement--in contrast with our understanding of the atmosphere, which is much more accessible to observation as well as more rapidly changing.  Crustal strength is best understood in deforming sedimentary basins where the petroleum industry has made great contributions, particularly in deforming petroleum basins because of the practical need to predict. In this talk we take a broad look at key issues in crustal strength and deformation and what we can learn from boreholes, earthquakes, active fault systems, and toy models.
