Large deployable antenna program. Phase 1: Technology assessment and mission architecture

The program was initiated to investigate the availability of critical large deployable antenna technologies which would enable microwave remote sensing missions from geostationary orbits as required for Mission to Planet Earth. Program goals for the large antenna were: 40-meter diameter, offset-fed paraboloid, and surface precision of 0.1 mm rms. Phase 1 goals were: to review the state-of-the-art for large, precise, wide-scanning radiometers up to 60 GHz; to assess critical technologies necessary for selected concepts; to develop mission architecture for these concepts; and to evaluate generic technologies to support the large deployable reflectors necessary for these missions. Selected results of the study show that deployable reflectors using furlable segments are limited by surface precision goals to 12 meters in diameter, current launch vehicles can place in geostationary only a 20-meter class antenna, and conceptual designs using stiff reflectors are possible with areal densities of 2.4 deg/sq m

Florida on the Eve of the Civil War as Seen by a Southern Reporter

In the days prior to the firing on Fort Sumter, readers of the Charleston Daily Courier were kept well informed on current events by its various correspondents. No paper in the South was better supplied with journalists, who sent in weekly, and often daily, reports from centers of interest. One of these reporters styled himself “Batchelor,” and he made a tour of Florida for the Courier

The Power of the Written Word and the Spoken Word in the Rise and Fall of William Lee Popham

William Lee Popham first came to the small fishing and lumbering town of Apalachicola in 1916. Seat of government for Franklin County in northwest Florida and located at the mouth of the Apalachicola River, the town had an aesthetic appeal. Equally important, it enjoyed strategic economic advantages. As a port opening to the Gulf of Mexico, antebellum Apalachicola imported manufactured goods and luxuries and shipped them by steamboats up the Apalachicola River and beyond. They went to individuals and businesses in north Florida, southwest Georgia, and southeast Alabama. In turn, Apalachicola received timber and agricultural products, especially cotton, from the interior and transhipped them to American and international markets. It became Florida’s premier port of shipment and third on the Gulf of Mexico after New Orleans and Mobile. With little agricultural income from Franklin County’s poor soil or from limited urban manufacturing, Apalachicola became a conduit of trade. It prospered from the 1830s through the mid-1850s. Yet, over sixty years before the exuberant Popham came to town, Apalachicola had begun to decline

A Description of the Naval War College Management Study

The study of management is a relative newcomer to the War College curriculum and may seem somewhat anomalous among the more traditional studies of strategy and tactics

Newspaper Mottoes in Ante-Bellum Florida

Southern newspapers before the Civil War were individualistic, caustic, and for the most part politically partisan. The typical newspaper devoted a page to foreign news, contained a section devoted to literary items, and had an outspoken editorial page. Editors borrowed liberally from each other, usually but not always citing the sources of their borrowings. The last page was filled with advertisements but they were also scattered throughout the paper, frequently appearing on page one

A Great Stirring in the Land: Tallahassee and Leon County in 1860

On the eve of the Civil War Tallahassee and Leon County were the center of Florida’s economic, political, and social life. Tallahasseans read about themselves in their two weekly, and decidedly political, newspapers: the strongly Democratic Floridian and Journal (circulation 1,500) and the Whiggish Florida Sentinel (circulation 1,000). As a national force the Whigs had disintegrated, but the Florida Sentinel retained the party’s principles. Local people kept further informed by talking among themselves. Conversations ranging from philosophical discussions to plain gossip were held on street corners, at stores, at churches, and at meetings of clubs and fraternal orders such as Jackson Lodge, No. 1, the state’s oldest masonic organization

As to the People : Thomas and Laura Randall\u27s Observations on Life and Labor in Early Middle Florida

Moving from Baltimore to the wilds of Florida in 1827 held for Thomas and Laura Wirt Randall both promise and uncertainty. He had practiced law in Maryland and would preside as a superior court judge in Florida. Laura, the daughter of United States Attorney General William Wirt, came from a similarly cloistered background and was ill-prepared for life on the frontier. The recently married couple settled in Jefferson County, in the heart of Middle Florida, a region bounded on the east and west by the Suwanee and Appalachicola rivers and containing some of the South’s more fertile soil.1 It was here, in what Randall refers to as the “woods country,” that they built a home and named the new residence Belmont
