Baltimore is the largest city in Maryland and one of the busiest ports in the United States. Its economy focuses on research and development, especially in the areas of aquaculture, pharmaceuticals, and medical supplies and services. Before European settlement, the site of Baltimore was inhabited by Native Americans of the Susquehannock tribe. The town was founded in 1729 and named for the barons Baltimore, the British founders of the Maryland Colony. This ASTER image of Baltimore was acquired on April 4, 2000, covers an area of 17 by 20 km, and is located at 39.3 degrees north latitude and 76.7 degrees west longitude. http://photojournal.jpl.nasa.gov/catalog/PIA11089

During Spring 2003, students, teachers, and scientists worked side-by-side, measuring the properties of aerosols fine particulate matter suspended in the air over Baltimore, Maryland using hand-held instruments shown here by NASA Terra spacecraft.

SL3-83-166 (July-September 1973) --- A vertical view of the Washington D.C. and the Baltimore, Maryland area is seen in the Skylab 3 Earth Resources Experiments Package S190-B (five-inch Earth terrain camera) photograph taken from the Skylab space station in Earth orbit. The Chesapeake Bay is on the right (east) side of the picture. The Potomac River flows through the Washington area in the lower left (southwest) corner of the photograph. Several transportation routes and major highways stand out very distinctly. Especially conspicuous are the beltways around the cities, Interstate 95 between Baltimore and the nation?s capitol and Interstate 70N leading west from Baltimore. The tunnel and harbor facilities in Baltimore show clearly, also. Identifiable features in the Washington area include the Capitol Building, the Mall area, Robert F. Kennedy Stadium (white circle), the five bridges across the Potomac, Andrews Air Force Base (on east loop), and the smaller Anacostia River. The extent of the urbanization in this area is dramatically illustrated in this picture. The photograph has sufficient resolution that the housing patterns for individual suburban areas are clearly defined with the houses shown as pink gray, wooded areas as dark green and cleared areas light green. Chesapeake Bay circulation patterns are indicated by contrast of dark and light blue. Sediment plumes (red) are seen entering the bay north and east of Baltimore. The bay bridge stands out white against the blue water. The detailed information contained in this one photograph will be of direct use to several EREP investigator teams in land use analysis, sedimentation and circulation patterns in the bay, and resource surveys of Maryland. All EREP photography is available to the public through the Department of Interior?s Earth Resources Observations Systems Data Center, Sioux Falls, South Dakota, 57198. Photo credit: NASA

STS098-716-057 (7-20 February 2001) --- Baltimore, Maryland can be identified in this northwest-looking view, photographed with a 70mm handheld camera from the Space Shuttle Atlantis, which shows the western shore of Chesapeake Bay. Numerous drowned river valleys provide excellent natural harbors along the periphery of the bay. Baltimore’s harbor has been developed along one of these drowned valleys, the Patapsco River. With a population of over 2.5 million people, the greater Baltimore urban area is part of the northeastern U.S. Megalopolis that extends from the Boston (MA) area to Richmond (VA). Specific features that can be seen in the image include a short segment of Interstate Highway 95 that connects southwest Baltimore with northeast Washington, D.C.; the intersecting runways of Baltimore-Washington International Airport south of downtown Baltimore; Francis Scott Key Bridge that skirts around the southeast side of Baltimore; the Chesapeake Bay Bridge that spans the bay and connects the Baltimore area with the eastern shore of Maryland; and the central business district of Baltimore where the two arms of the inner harbor terminate. The darker-looking vegetation cover is mixed hardwood forests (notice that many wooded areas are located along streambeds and floodplains of small river valleys), while lighter-looking land parcels in the rural countryside is used for crops or pasturelands.

Philadelphia lies in the center of this image from NASA Terra satellite. Larger cities, including New York, Newark, Philadelphia, Wilmington, Baltimore and Washington D.C., are visible from upper right to lower left.

ISS033-E-014186 (16 Oct. 2012) --- A nighttime view of Baltimore, Maryland is featured in this image photographed by an Expedition 33 crew member in the International Space Station. Baltimore is located on the U.S. mid-Atlantic coastline along the terminus of the Patapsco River into Chesapeake Bay, and is the largest seaport along this part of the coast. Like many large U.S. metropolitan areas, the most brightly lit area corresponds to the highest density of buildings and typically indicates the urban core -- in this case, downtown Baltimore at center. Highways and large arterial streets appear as bright yellow-orange lines extending outwards from the downtown area into the surrounding suburban regions (light violet and reddish brown regions of diffuse lighting). Dark areas beyond the suburban zone are rural - or to the southeast, indicate the waters of Chesapeake Bay. Small dark patches within the metropolitan area are open space including parks, cemeteries, and the Baltimore Zoo (top left). Two large, brightly-lit areas along Chesapeake Bay are commercial/industrial regions, and include the major port facilities for Baltimore. The City of Baltimore was incorporated in 1796, after serving as the de facto capital of the nascent United States of America during the Second Continental Congress (from Dec. 20, 1776 to March 4, 1777). Today, the Baltimore metropolitan area (as defined by the Baltimore Metropolitan Council) includes over 2.5 million people and includes six Maryland counties (Anne Arundel, Baltimore, Carroll, Harford, and Howard) in addition to the City of Baltimore. The region is also a focus of urban ecological research through the Baltimore Ecosystem Study.

SL2-05-393 (22 June 1973) --- The nation's capital lies astride the Potomac River (38.5N, 77.5W) at the head of the Potomac Estuary. Baltimore, MD, also in the scene, is connected to Washington by the Baltimore-Washington Parkway. The suburbs of both cities tend to cluster around the Washington and Baltimore Beltways. Most of the countryside in the eastern two-thirds of this scene is either heavily forested or is in farming, dairy operations or poultry production. Photo credit: NASA

City lights shine brighter during the holidays in the United States when compared with the rest of the year, as shown using a new analysis of daily data from the NASA-NOAA Suomi NPP satellite. Dark green pixels are areas where lights are 50 percent brighter, or more, during December. Because snow reflects so much light, the researchers could only analyze snow-free cities. They focused on the U.S. West Coast from San Francisco and Los Angeles, and cities south of a rough imaginary line from St. Louis to Washington, D.C.
