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.

With the increasing size of the seismic data volumes, machine learning applications have been found to accelerate the discrimination of seismic facies used in the identification of geologic patterns, defining stratigraphy and the direct indication of hydrocarbons. Many practitioners have demonstrated the application of dimensionality reduction tools such as principal component analysis and independent component analysis, or clustering techniques. Some of these are available in several commercial interpretation software packages.

In the world of oil and gas, an increasing number of plays in stratigraphic traps are being made – in large part due to ever-evolving seismic technology. The Discovery Thinking forum at the annual IMAGE conference in August served to highlight some of these plays in offshore frontier basins and the role that geophysics played in their discovery. “We are seeing more giant stratigraphic fields, and seismic is the key,” said past AAPG President Charles A. Sternbach, chair of the Discovery Thinking forum. “And, we are seeing more oil found at greater depths. Unconventional plays are migrating outside of the Western Hemisphere.”

In June of 2020, I set out to hike just the first 470 miles of the Appalachian Trail. Less than two weeks into my adventure, I thought to myself, “What the heck, why not do the whole thing?” It was then that I decided to hike the entirety of the nearly 2,200 miles that summer. I later decided that I would also write a book about it. “Rocks, Roots and Rattlesnakes” is that story of my daily adventures, as written from a geologist’s perspective.

The war between Russia and Ukraine has seen several phases since the initial invasion in February. A series of advances by the Ukraine armed forces in the Eastern part of the country in early September created the impression that the conflict might be near an end. Russian annexation of four provinces at the end of the month convinced others that the war is far from over. What is not debatable, however, are the devastating effects that the war continues to have, particularly on Ukrainian refugees who fled hundreds or thousands of miles to escape the turmoil and seek safety for themselves and their families. This is the second in a two-part series about Ukrainian geologist refugees who fled their homeland and received assistance from colleagues living around the world, which shares the stories of other geoscientists who benefitted greatly from the funding but still struggle to find stability after having their world turned upside-down.

“It takes a village to raise a new generation of Earth scientists, and our societies are our village.” Those words are not engraved on the door of the East Texas Geological Society, nor any other geological society in America, but if you talk to Julie Bloxson, assistant professor of geology at Stephen F. Austin State University in Nagadoches, they should be. At their best, she said, geological societies, “Create a space to share information, socialize and pass along information to the next generation of geoscientists.”

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.

Natural disasters worldwide, public debate, policy decisions and shareholder pressure are just some of the factors motivating companies to seek alternatives to traditional oil and gas to fuel the ever-increasing demand for energy worldwide. One of those alternatives is hydrogen – a renewable energy source that proponents believe brings a wealth of opportunities and challenges. Argentina’s national energy company YPF is one such proponent. They are considering using natural gas from the massive Vaca Muerta play to produce “blue hydrogen,” which is produced by combining natural gas and steam.

If the world had a comprehensive plan to address climate change, what would it look like? That’s an important question, even a crucial question for industry and businesses globally, especially the energy industry. Companies need to plan for significant climate-related action coming in the years and decades ahead. “The world does have a climate plan – or rather, a lot of plans. There’s a ton of economic and climate models that have been done around various pathways,” said Derek Pankratz, senior research manager with the Center for Integrated Research in Deloitte Services LP.
