Deep within the hushed corridors of a facility in Suitland, Maryland, lies a collection so vast it feels less like a museum and more like an above-ground catacomb. This is the Smithsonian Museum Support Center (MSC), a sprawling complex of cream-colored cabinets and kilometers of shelving that houses some of the most extraordinary Smithsonian secrets most likely to blow your mind. While the public flocks to the National Mall in Washington, D.C., the true weight of the institution’s biological and geological record is held here, tucked away in massive storage pods.
The MSC was established in 1983 to alleviate overcrowding at the National Museum of Natural History, which maintains a collection of nearly 150 million objects. These are not merely curiosities; they are “forever” collections. As a physician and medical writer, I find the intersection of these archives and public health particularly striking. These specimens provide a physical baseline of the planet’s health, allowing scientists to track environmental degradation and evolutionary shifts across centuries.
The scale of the operation is staggering. The center currently operates five storage pods, each roughly the size of a football field and nearly three stories tall. To protect these irreplaceable items from floods, fires, and power outages, the facility employs 24/7 security and rigorous climate controls. The risks are diverse: while dried specimens fear water, the “wet collection” faces the opposite threat—evaporation or, in extreme cases, the risk of alcohol-filled jars exploding.
The Biological Archive as a Scientific Time Machine
The value of the MSC extends far beyond curation; it is an active laboratory. By analyzing these archives, researchers can answer questions that were inconceivable when the specimens were first collected. For example, scientists are currently utilizing the collection to analyze DNA from an African elephant population that has long remained elusive to human observers.
The archives as well serve as a critical tool for forensic ecology. Decades ago, researchers studied bird eggs preserved in these collections to discover that the insecticide DDT was causing shells to thin. This discovery was pivotal in revealing how the chemical nearly drove several species, including the bald eagle, to extinction. According to Kirk Johnson, director of the National Museum of Natural History, these collections create a “cloud of knowledge about the planet” that would otherwise be lost to time.
In an era dominated by artificial intelligence and digital simulations, the physical reality of the MSC provides an essential anchor. Rebecca Johnson, the museum’s chief scientist, notes that “people still want to know what is real,” and the MSC is the definitive place where the “real thing” is preserved.
The Unsung Heroes of Bone Preservation
One of the most surprising “staff members” at the MSC isn’t human. The hide beetle (Dermestes maculatus) and its larvae are essential to the museum’s osteological preparations. These insects are tasked with cleaning animal bones by eating away remaining tissue, a process that is far more precise than allowing flesh to rot in water, which often results in a disorganized pile of bones.
The efficiency of these beetles is remarkable. In 2025, the beetles were responsible for cleaning 429 skeletons. While a hummingbird’s bones can be stripped in less than a day, a massive whale skull may take several months of meticulous work. Once the beetles have finished, osteological specimen preparator Inger Toraason removes any remaining remnants by hand and treats the bones with a degreasing solution to ensure long-term stability.
Botanical Oddities and Sensory Marvels
The Smithsonian Gardens Orchid Collection contains specimens that challenge our traditional perceptions of floral beauty. Some utilize mimicry and scent to survive in the wild, creating experiences that are as olfactory as they are visual.
The tongue orchid (Bulbophyllum fletcherianum) is one of the largest orchid species on Earth, with leaves reaching nearly two meters in length. Though, it is most famous for its scent; when in bloom, it emits the fragrance of “fetid flesh” to attract carrion beetles and blow flies. In contrast, the Dracula orchid (Dracula chimaera ‘Pacifica’) targets fungus gnats by mimicking the scent and appearance of mushrooms, featuring fine ribs on its central petal that resemble mushroom gills.
| Specimen | Key Characteristic | Biological Purpose/Function |
|---|---|---|
| Tongue Orchid | Rotting flesh scent | Attracts carrion-seeking pollinators |
| Dracula Orchid | Mushroom mimicry | Attracts fungus gnats via scent and gills |
| Hide Beetle | Tissue consumption | Cleans skeletons for anatomical study |
| Raggiana Bird-of-Paradise | Vibrant red plumage | Ritual dance and courtship display |
The Scale of the ‘Wet Collection’
Perhaps the most visually overwhelming section of the MSC is the wet collection. Roughly 25 million specimens—including octopuses, slipper lobsters, coral, and shrimp—are preserved in fluid. These specimens occupy approximately 72 kilometers of shelving, a distance more than four times the length of the trails leading to the bottom of the Grand Canyon.
Maintaining this archive requires a constant battle against chemistry. The jars contain nearly two million liters of ethanol, which must be regularly topped off to prevent the specimens from drying out and deteriorating. This massive liquid library allows researchers to study soft-tissue anatomy that would be lost in traditional taxidermy.
Cultural Records and Ritual Artifacts
The MSC also archives the human experience through cultural objects. Among these are the Raggiana bird-of-paradise (Paradisaea raggiana) headdress ornaments, which entered the collection in 1946. Originating from what is now Papua New Guinea, these ornaments were designed for movement.
Globalization curator Joshua Bell explains that during ritual performances, the rapid motion of the dancers combined with glinting light would blur the red feathers. This effect was intended to make the dancers appear as if they were transforming into birds themselves, bridging the gap between the human and natural worlds.
As the institution continues to grow, the facility is expanding to meet the needs of future generations. A sixth storage pod is currently in development to accommodate the ever-increasing influx of biological and cultural data. This expansion ensures that the “record of the world” remains intact for the scientists of the next century.
