A Most “Pleasantly Situated” Estate

A Most “Pleasantly Situated” Estate
August 25, 2024

Editor’s note: In honor of America’s 250th birthday, Earth Observatory is revisiting stories about the landscapes that helped shape U.S. history. The images and text on this page were originally published on February 17, 2025. Explore the full collection here.

George Washington was born in 1732 on his family’s tobacco plantation at Popes Creek in Westmoreland County, Virginia. Three years later, he moved up the Potomac River to Little Hunting Creek Plantation, a property later renamed Mount Vernon. The riverside property, approximately 15 miles (24 kilometers) south of Washington, D.C., was central to the man who became the first U.S. president.

Though the family soon moved to Fredericksburg, Virginia, and resided there for much of his youth, Washington began managing the Mount Vernon property in 1759, soon after his marriage to Martha Dandridge. Washington’s letters make clear that he cherished and longed for this place during his long absences as a surveyor, military commander, and politician—a location he called the most “pleasantly situated” estate in the United States. It was where he helped raise two stepchildren, four step-grandchildren, and an array of crops and livestock. It was also where he was laid to rest in 1799 at the age of 67.

The OLI (Operational Land Imager) on Landsat 8 captured this image of Mount Vernon and its surroundings on August 25, 2024. While much of the land surrounding the estate has been developed into things like suburban neighborhoods, shopping areas, and military bases, fragments of the pristine forests, farmland, and riverscapes that Washington would recognize remain.

In a 1793 letter to Arthur Young, an English agricultural expert and reformer, Washington expounded on the virtues of Mount Vernon’s land.

It lyes in a high, dry & healthy country, 300 miles by water from the Sea—and, as you will see by the plan, on one of the finest Rivers in the world. Its margin is washed by more than ten miles of tidewater; from the bed of which, and the enumerable coves, inlets & small marshes with which it abounds, an inexhaustable fund of rich mud may be drawn as a manure; either to be used seperately, or in a compost.

Toward the end of his life, Washington’s land holdings extended across five farms centered on Mount Vernon. The map below, based on one of Washington’s drawings, shows their layout. The Mansion House Farm encompassed Mount Vernon, with Union Farm and Dogue Run Farm to the west. Muddy Hole Farm lay to the north and River Farm to the east.

An 1801 map of Mount Vernon from a drawing provided by George Washington. Four other farms that were part of Washington’s land holdings are situated around Mount Vernon.

Washington was known as an innovative landowner who, with the labor of hundreds of enslaved people, took unusual care to manage his crops sustainably. For instance, he shifted much of his production to wheat and corn and started experimenting with a seven-year crop rotation system and cover crops to better preserve the health of his soil after realizing that growing tobacco depleted its fertility.

While most crops were raised at the outlying farms, Mount Vernon’s gardens were showcases for visitors and laboratories for experimentation. The showy upper garden was a formal garden near the mansion with carefully trimmed dwarf boxwood hedges and a heated greenhouse with lemons, oranges, and rare plants.

Closer to the river was the lower garden, a kitchen garden brimming with vegetables, and a small garden that Washington called “my botanick garden,” where he spent much of his time experimenting with new varieties. Even closer to the river was the fruit garden, an experimental orchard where the estate raised pears, cherries, peaches, and apples. This may have been the source of the centuries-old preserved cherries that archaeologists unearthed in Mount Vernon’s cellar in 2024.

A wider view of the satellite image includes more of the Potomac River and all of Washington, D.C.

The lands connecting the five farms—his “wilderness,” Washington called it—were a forested area where he often spent time hunting and fishing. Species such as oak, hickory, and heath shrubs dominated the forests in Washington’s time. Dozens of the same plant species from that period are still found on the estate’s forests in modern times, though large numbers of non-native species have established themselves as well.

One of the larger open spaces visible in the Landsat image above is Fort Hunt Park. Once part of Washington’s River Farm, Fort Hunt was constructed in 1897 to bolster Washington D.C.’s defenses during a period of heightened tensions with Spain. Across the Potomac River stands Fort Washington Park, home to ruins of a fort that was used to defend the city during the Mexican-American War and the American Civil War.

Across the river in Maryland lies another property with a connection to George and Martha Washington. National Colonial Farm in Piscataway Park was established in 1958 to preserve the couple’s beloved views across the Potomac. Today, National Colonial Farm is a living farm museum and features several 18th-century heirloom varieties of herbs, flowers, and vegetables, including “Orinoco” tobacco, red May wheat, and Virginia white gourdseed corn.

Starry Chandelier Cluster

2026-06-30 15:02

A globular cluster. It holds many thousands of bright stars, tightly packed in the center and spread out in its outer regions, but filling the entire view. The stars are colored either orange or bright blue, with the blue stars mainly concentrated in the center. Orange stars are located mainly around the edge and vary in size from small dots to glowing stars with four points, based on their position in the foreground or background of the cluster.

This image released on June 26, 2026, features the globular cluster NGC 6723, sometimes called the Chandelier Cluster. Like its namesake, it sparkles with countless lights. However, each ‘lightbulb’ in this chandelier is an individual star 27,000 light-years away in the constellation Sagittarius (the Archer).

Globular clusters like NGC 6723 contain some of the oldest stars in our galaxy. These clusters have ages that often exceed 10 billion years old, and some are nearly as old as the universe itself. Astronomers think globular clusters are some of the first structures that formed in our galaxy, coalescing potentially billions of years before the thin disk of stars in which our Sun orbits. The details of how globular clusters formed, however, are not yet certain.

Northwest Earth and Space Science Pathways Project Celebrates Student Innovation Through ROADS from Earth to Venus National Challenge

The Northwest Earth and Space Science Pathways (NESSP) project recently concluded its 2025–2026 ROADS (Rover Observation And Discoveries in Space) from Earth to Venus National Challenge, a NASA Science Activation program student challenge that engaged more than 500 students on 120 teams from eight states in authentic science and engineering experiences inspired by Venus exploration.

The challenge began with educator professional development in August 2025, preparing teachers and mentors to guide students through the ROADS experience. Registered teams then worked through challenge checkpoints from January through May 2026, with in-person Hub events held in April and May 2026 to give students opportunities to showcase their work, connect with peers, and engage with NASA-inspired STEM (Science, Technology, Engineering, and Mathematics) activities.

NESSP, led by Central Washington University in Ellensburg, Washington, creates opportunities for students and educators to connect with NASA science through hands-on STEM learning. The ROADS framework challenges upper elementary, middle, and high school students to work collaboratively on mission-inspired activities that mirror the ways NASA scientists and engineers investigate planetary environments and prepare for future exploration.

Throughout the academic year, ROADS from Earth to Venus teams completed eight Mission Objectives focused on science, engineering, teamwork, and communication. Students documented their work in Mission Development Logs, designed mission patches, modeled carbon movement on Earth and Venus, investigated the greenhouse effect, collected remote sensing data using kite-mounted cameras, programmed robotic rovers to navigate Venus-inspired terrain, explored NASA-related careers, and presented their final mission stories through virtual submissions and regional Hub events.

In addition to completing the challenge virtually, many students participated in in-person Hub events hosted by NESSP partner institutions, including Central Washington University, Montana State University, and Northern Arizona University. These events gave teams the opportunity to showcase their work, exchange ideas with peers, interact with mentors, and experience college campuses as part of a broader STEM learning community.

“The ROADS Challenge gives students the opportunity to do more than learn about NASA missions – they become part of the mission,” said Dr. Darci Snowden, Director of NESSP. “I am especially proud of this year’s teams. Students took on an exceptionally broad set of mission objectives, from modeling carbon cycles and designing experiments to conducting remote sensing operations with kites and programming rovers to navigate challenging terrain while collecting scientific data. These students participated because they were curious, motivated, and eager to learn. By investigating authentic mission challenges, collaborating with teammates, and sharing their ideas with others, students develop the confidence and skills needed to see themselves as future scientists, engineers, educators, and explorers.”

NESSP recognized top teams across elementary, middle, and high school divisions for outstanding participation and exemplary Mission Development Logs.

In the Elementary School Division, NESSP recognized The Evil Twins, The Acid Clouds, Flaming Asteroid Nebulas, and The NASA Intelligence, all from Silverdale, Washington.

In the Middle School Division, NESSP recognized Venus Ascenders from Mukilteo, Washington; Project Fuego Venus from Safford, Arizona; Galaxy Dragons from Sequim, Washington; The Four Folds from Hardin, Montana; and Crater Lake Crusaders from Medford, Oregon.

In the High School Division, NESSP recognized Laborantem from Columbus, Montana; Velocity to Venus from Sequim, Washington; Puget Sound Propulsion from Mukilteo, Washington; and Evergreen Explorers from Mukilteo, Washington.

Highlights from this year’s challenge, including student presentations and special recognitions, are available through the ROADS from Earth to Venus Virtual Recognition Ceremony on the NESSP YouTube channel, @nwessp.

Educators, families, and community organizations can continue to access ROADS from Earth to Venus activities and educational resources, along with materials from previous ROADS challenges, through the NESSP website at www.nwessp.org.

NASA’s Northwest Earth and Space Science Pathways project is supported by NASA cooperative agreement award number 80NSSC22M0006 and is part of NASA’s Science Activation Portfolio, which connects learners with authentic NASA science experiences through partnerships with educators and community organizations.

NASA and the U.S. Small Business Administration (SBA) launched the SBIC-NASA Initiative on Monday to increase investment in American manufacturers of industrial components and providers of technologies critical to space exploration to support a sustained presence on the Moon and Mars. 

Under the Memorandum of Agreement, NASA will identify technology priorities and connect businesses to funding opportunities through the agency’s new NASA Office of Strategic Capital. The initiative also will be a part of SBA’s Small Business Investment Company (SBIC) Program, which provides leverage that matches private capital raised by investment funds and is designed to enhance fund-level investment returns.

“To achieve President Trump’s National Space Policy, NASA needs a stronger industrial base capable of moving at the speed this new space race demands,” said NASA Administrator Jared Isaacman. “Through the NASA Office of Strategic Capital, this partnership with the SBA will help small businesses access the capital they need to scale, strengthen critical supply chains, rebuild America’s industrial might, and deliver the outcomes necessary to ensure the United States leads the next era of space exploration.”

By augmenting the investable capital for investment funds licensed by the SBA under this SBIC-NASA Initiative, the new initiative expands access to capital for small businesses within the space industry.

“To meet President Trump’s objective of securing American leadership on every frontier, the SBA and NASA are partnering to supercharge the industrial base behind our space program and connect the innovators building critical technologies with needed capital,” said SBA Administrator Kelly Loeffler. “Through this partnership with NASA, the SBA is mobilizing private sector investment to fuel the small businesses, manufacturers, and innovators that are driving American space dominance. By aligning capital with strategic national priorities, this exciting effort will help launch the next great era of space exploration.”

Under the agreement, NASA will define strategic aerospace technology focus areas and identify supply chain needs. The SBA will use those priorities to attract and license qualified private investment funds that commit to invest at least 60% of their capital into NASA-identified focus areas, including:

  • Energy production, infrastructure, and storage
  • Nuclear power and propulsion
  • Advanced software, avionics, and communications systems
  • Specialized materials and components
  • Inhospitable environment infrastructure
  • Scaled launch infrastructure
  • Biomedical and life support technology

Through this partnership between NASA and SBA, capital will flow into space industry sectors and upstream supply chain components vital to the National Space Policy and critical to national and economic security.
