Goddard Rocket Launching Site
The Goddard Rocket Launching Site is a National Historic Landmark commemorating the launch site of the world's first successful liquid-fueled rocket. History Dr. Robert H. Goddard launched his historic rocket on March 16, 1926, from what was then the Asa Ward Farm. The rocket reached an altitude of , flew for two-and-a-half seconds, and fell to the ground from the launching frame. Goddard's final launch from Auburn, on July 17, 1929, was also a historic first. The rocket carried an aneroid barometer, thermometer, and a camera triggered when the parachute opened. All three instruments operated successfully and were recovered. The rocket achieved a maximum altitude of in an 18.5-second flight covering a distance of . The site was declared a National Historic Landmark A National Historic Landmark (NHL) is a building, district, object, site, or structure that is officially recognized by the United States government for its outstanding historical significance.

Auburn, Massachusetts
Auburn is a town in Worcester County, Massachusetts, United States. The population was 16,889 at the 2020 census. History The Auburn area was first settled in 1714 as of today outer parts of Worcester, Sutton, Leicester and Oxford, Massachusetts, and the town was officially incorporated on April 10, 1778, as the town of Ward, in honor of American Revolution General Artemas Ward. The town changed its name to Auburn in 1837, after the Post Office complained that the name was too similar to the nearby town of Ware. Before incorporation, most of Auburn was known as the South Parish of Worcester; other portions fell within the town limits of Leicester and Millbury. Today, Auburn is bordered by Worcester to the north, Leicester to the west, Millbury to the east, and Oxford to the south. Robert H. Goddard launched the first liquid-fueled rocket from Pakachoag Hill, on his aunt Effe Ward's farm, in Auburn on March 16, 1926. Goddard is commemorated in Goddard Memorial Park, located ...

National Historic Landmark
A National Historic Landmark (NHL) is a building, district, object, site, or structure that is officially recognized by the United States government for its outstanding historical significance. Only some 2,500 (~3%) of over 90,000 places listed on the country's National Register of Historic Places are recognized as National Historic Landmarks. A National Historic Landmark District may include contributing properties that are buildings, structures, sites or objects, and it may include non-contributing properties. Contributing properties may or may not also be separately listed. Creation of the program Prior to 1935, efforts to preserve cultural heritage of national importance were made by piecemeal efforts of the United States Congress. In 1935, Congress passed the Historic Sites Act, which authorized the Interior Secretary authority to formally record and organize historic properties, and to designate properties as having "national historical significance", and gave the Nation ...

Rocket
A rocket (from it, rocchetto, , bobbin/spool) is a vehicle that uses jet propulsion to accelerate without using the surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Signific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert H
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Aneroid Barometer
A barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries. Barometers and pressure altimeters (the most basic and common type of altimeter) are essentially the same instrument, but used for different purposes. An altimeter is intended to be used at different levels matching the corresponding atmospheric pressure to the altitude, while a barometer is kept at the same level and measures subtle pressure changes caused by weather and elements of weather. The average atmospheric pressure on the earth's surface varies between 940 and 1040 hPa (mbar). The average atmospheric pressure at sea level is 1013 hPa (mbar). Etymology The word ''barometer'' is derived from the Ancient Greek (), meaning "weight", and (), meaning "measure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermometer
A thermometer is a device that temperature measurement, measures temperature or a temperature gradient (the degree of hotness or coldness of an object). A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury-in-glass thermometer or the digital readout on an infrared model). Thermometers are widely used in technology and industry to monitor processes, in meteorology, in medicine, and in scientific research. History While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale. Today there is an absolute thermodynamic temperature scale. Internationally agreed temperature scales are designed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of National Historic Landmarks In Massachusetts
The Commonwealth of Massachusetts has a total of 191 National Historic Landmarks (NHLs) within its borders. This is the second highest statewide total in the United States after New York, which has more than 250. Of the Massachusetts NHLs, 57 are in the state capital of Boston, and are listed separately. Ten of the remaining 134 designations were made when the NHL program was formally inaugurated on October 9, 1960; the most recent were in 2021. Cambridge is the city with the most NHLs outside Boston (at 19), and Middlesex County is home to 43 NHLs (again outside the 58 from Boston, which comprise all but two of the NHLs in Suffolk County). Every county in the state has at least one NHL ( Franklin County has exactly one, the Old Deerfield Historic District). The state's NHLs were chosen for a diversity of reasons. Some of the nation's oldest surviving structures are included: a number of 17th-century houses are listed, including the Fairbanks House (late 1630s) of Dedha ...

Monuments And Memorials On The National Register Of Historic Places In Massachusetts
A monument is a type of structure that was explicitly created to commemorate a person or event, or which has become relevant to a social group as a part of their remembrance of historic times or cultural heritage, due to its artistic, historical, political, technical or architectural importance. Some of the first monuments were dolmens or menhirs, megalithic constructions built for religious or funerary purposes. Examples of monuments include statues, (war) memorials, historical buildings, archaeological sites, and cultural assets. If there is a public interest in its preservation, a monument can for example be listed as a UNESCO World Heritage Site. Etymology It is believed that the origin of the word "monument" comes from the Greek ''mnemosynon'' and the Latin ''moneo'', ''monere'', which means 'to remind', 'to advise' or 'to warn', however, it is also believed that the word monument originates from an Albanian word 'mani men' which in Albanian language means 'remember ...

Buildings And Structures In Auburn, Massachusetts
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
