The land is always changing, sometimes by human hands: cities are built, farms expanded, and forests logged. Other changes lie mostly outside people's control: wildfires burn through communities, and hurricanes reshape coastlines. For most of the past four decades, observations from the Landsat satellite record show that humans have dominated changes to the U.S. landscape. Recent research revealed a shift in that trend, suggesting that disasters might be catching up.

Since my last post before moving to southern California was all about looking for nudibranchs in Northern California, I thought I'd follow it up and write about my experiences looking for nudibranchs down here. In the spirit of being inclusive I'm going to be discussing sea slugs in general, not just nudibranchs, since I've had very good luck spotting non-nudibranch sea slugs down here.

In April 2026, NASA's Artemis program took humanity back to the Moon, providing a new look at Earth's only natural satellite. As the world celebrates the return of Artemis II's four astronauts, the lunar surface continues to play a critical role in missions much closer to Earth.

Oakland used to brag about the quality of its streets, which were made of Oakland rock. Two things, an accident of geology and technological happenstance, meant our first roads were built starting around 1860 with macadam paving, the pre-asphalt method of constructing roadways with layers of clean, sterile crushed rock, each layer wetted down and compacted under heavy rollers.

The origins of Memorial Day lie in the U.S. Civil War, a conflict that led to the deaths of nearly 700,000 Americans. By the waning days of the war, makeshift military cemeteries had sprung up throughout the country, but especially in the South and Mid-Atlantic, where much of the fighting occurred.

As NASA advances technology for long-term exploration of the Moon and missions to Mars, one of the most challenging obstacles is propulsion, specifically, how to launch astronauts off the Martian surface for their journey home. Traditional rocket engines require massive amounts of fuel or propellant. Propellant is heavy and takes up a lot of room, which makes it challenging and expensive to design and transport for longer missions. Enabling this technology, will aid in NASA's ambitious exploration goals.

It's a truism among oceanographers that there is more accurate mapping of the surface of the Moon and Mars than of the deep-ocean floor. That's especially true for the Bismarck Sea, a relatively deep body of water north of Papua New Guinea. It's an ocean basin with a geologically complex seafloor rife with faults, volcanic features, rifts, scarps, and active subduction and spreading zones at depths that make high-resolution sonar mapping challenging.

Channel Islands National Park, a chain of five ecologically rich islands off the coast of mainland California, is known for its diversity of plant and animal species, earning it the nickname "North America's Galapagos." For part of May 2026, Santa Rosa Island--the park's second-largest island--was closed to the public as firefighters worked to contain a wildland fire burning through grassland, coastal sage scrub, and areas of island chaparral.

Dr. Kelly Korreck is the program scientist for the Living with a Star (LWS) program within the Heliophysics Division of NASA's Science Mission Directorate. She leads the strategic planning and programmatic management of the LWS mission portfolio, which focuses on the Sun-Earth system and its impact on life and society. In this role, she ensures that missions providing predictive understanding of space weather meet technical, budgetary, and scientific milestones to protect technology, communication systems, and human exploration in space.
