Earth observations during Space Shuttle Flight STS-46: Atlantis' Mission to Planet Earth

The photographic and videographic documentation of the Earth during STS-46 mission has enhanced the Space Shuttle Earth Observations Project (SSEOP) database. Increasing numbers of scientists are using this database; many are downloading the imagery from our electronic database for specific scientific analyses. We believe the scientific returns of the Earth Observations photography from this mission will add to the global change databases and will contribute to the better understanding of our home planet. The use of manned space flights in understanding the global process first hand is a vital component in NASA's Mission to Planet Earth. The following are discussed along with photographs from the mission: landforms and geologic observation; environmental observations; meteorological/atmospheric observation; and oceanographic observations.

Global geologic applications of the Space Shuttle earth observations photography database

The advantages of the astronaut photography during Space Shuttle missions are briefly examined, and the scope and applications of the Space Shuttle earth observations photography database are discussed. The global and multidisciplinary nature of the data base is illustrated by several examples of geologic applications. These include the eruption of Mount Pinatubo (Philippine Islands), heat flow and ice cover on Lake Baikal in Siberia (Russia), and windblown dust in South America. It is noted that hand-held photography from the U.S. Space Shuttle provides unique remotely-sensed data for geologic applications because of the combination of varying perspectives, look angles, and illumination, and changing resolution resulting from different lenses and altitudes.

Earth observations during Space Shuttle flight STS 50 - Columbia's mission to planet earth (June 25-July 9, 1992)

A review of the imagery acquired during the STS 50 mission of the Space Shuttle is presented. The earth viewing photography from this flight includes photos of dust plumes over several portions of the Red Sea, Arabian Sea, Persian Gulf, the Mediterranean Sea, and the Atlantic Ocean. Over land, prominent dust plumes were seen over Iraq, North Africa, Sudan, and West Africa. The color infrared photography includes images of the tropical rain forests of South America and South and Southeast Asia. Other examples include photographs of floods in Argentina, photos of Lake Chad in Africa, Coastal Madagascar, the Aswan dam and the Nile, geologic features of North Africa, the center pivot irrigation land areas of Saudi Arabia, flooding in Asian rivers, and sediment plumes of South American and South and Southeast Asian coasts.

Earth observations during Space Shuttle Mission STS-42 - Discovery's mission to planet earth

The noteworthy imagery acquired during Space Shuttle Mission STS-42 is documented. Attention is given to frozen Tibetan lakes, Merapi Volcano in Java, Mt. Pinatubo in the Philippines, the coastline east of Tokyo Japan, land use in southern India, and the Indus River Delta. Observations of Kamchatka Peninsula, Lake Baikal, Moscow, Katmai National Park and Mt. Augustine, Alaska, the Alaskan coast by the Bering Sea, snow-covered New York, the Rhone River valley, the Strait of Gibraltar, and Mt. Ararat, Turkey, are also reported.

Earth observations during Space Shuttle flight STS-29 - Discovery's voyage to the earth

The environmental, geologic, meteorologic, and oceanographic phenomena documented by earth photography during the Space Shuttle STS-29 mission are reviewed. A map of the nadir point positions of earth-viewing photographs from the mission is given and color photographs of various regions are presented. The mission photographs include atmospheric dust and smoke over parts of Africa and Asia, Sahelian water sites, center pivot irrigation fields in the Middle East, urban smog over Mexico City, isolated burning in the Bolivian Amazon, and various ocean features and cloud formations.

Medium format cameras used by NASA astronauts

The medium format cameras and other hardware used for photographing the earth from the Space Shuttle are discussed. Illustrations and descriptions are given for the two types of cameras used for most earth photography, the NASA-modified Hasselblad 500 EL/M 70-mm cameras and the Linhof AeroTechnika 45 camera. Also, the data recording modules used on Space Shuttle missions and a mounting device to produce simultaneous photography using two cameras are examined.
