Vega (rocket)
Vega (, , ) was a European expendable small-lift launch vehicle developed by Avio and operated by Arianespace for the European Space Agency (ESA) and the Italian Space Agency (ASI). Designed to carry payloads between into low Earth and polar orbits, Vega served primarily scientific and Earth observation missions. Development of Vega began in 1998, with its maiden flight launched from the Guiana Space Centre on 13February 2012. Over the next decade, it became the eighth most launched small-lift launch vehicle history, though it struggled to compete in the commercial launch market. After initial success, two in-flight failures and rising competition from SpaceX's rideshare programs, which offered lower prices, relegated Vega to primarily serving European government agencies willing to pay more to support independent space access. The rocket took its name from Vega, the brightest star in the constellation Lyra. It featured a single-body design without strap-on boosters, con ...

Landsat
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from ; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wide ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SPOT (satellite)
SPOT (, lit. "Satellite for observation of Earth") is a commercial high-resolution optical Earth observation satellite system operating from space. It is run by Spot Image, based in Toulouse, France. It was initiated by the CNES (''Centre national d'études spatiales'' – the French space agency) in the 1970s and was developed in association with the SSTC (Belgian scientific, technical and cultural services) and the Swedish National Space Board (SNSB). It has been designed to improve the knowledge and management of the Earth by exploring the Earth's resources, detecting and forecasting phenomena involving climatology and oceanography, and monitoring human activities and natural phenomena.

Mediterranean Sea
The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccation, desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The sea was an important ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
