A geosynchronous transfer orbit or geostationary transfer orbit (GTO) is a Hohmann transfer orbit—an elliptical orbit used to transfer between two circular orbits of different radii in the same plane—used to reach geosynchronous or geostationary orbit using high-thrust chemical engines.
The Molniya series satellites are military and communications satellites launched by the Soviet Union from 1965 to 2004. These satellites use highly eccentric elliptical orbits known as Molniya orbits, which have a long dwell time over high latitudes. They are suited for communications purposes in polar regions, in the same way that geostationary satellites are used for equatorial regions.
A Molniya orbit is a type of satellite orbit designed to provide communications and remote sensing coverage over high latitudes. It is a highly elliptical orbit with an inclination of 63.4 degrees, an argument of perigee of 270 degrees, and an orbital period of approximately half a sidereal day. The name comes from the Molniya satellites, a series of Soviet/Russian civilian and military communications satellites which have used this type of orbit since the mid-1960s.
Ofeq, also spelled Offek or Ofek is the designation of a series of Israeli reconnaissance satellites first launched in 1988. Most Ofeq satellites have been carried on top of Shavit rockets from Palmachim Airbase in Israel, on the Mediterranean coast. The Low Earth orbit satellites complete one earth orbit every 90 minutes. The satellite launches made Israel the eighth nation to gain an indigenous launch capability. Both the satellites and the launchers were designed and manufactured by Israel Aerospace Industries (IAI) with Elbit Systems' El-Op division supplying the optical payload.

Pardon My Sarong is a 1942 comedy film starring Abbott and Costello.
The Intelsat VI series of satellites were the 8th generation of geostationary communications satellites for the Intelsat Corporation. Designed and built by Hughes Aircraft Company (HAC) in 1983-1991, there were five VI-series satellites built: 601, 602, 603, 604, and 605.
TarcherPerigee is a book publisher and imprint of Penguin Group (USA) focused primarily on mind, body and spiritualism titles. Jeremy P. Tarcher Inc. was founded in 1973 in Los Angeles by Jeremy P. Tarcher (1932–2015), husband of actress, singer and ventriloquist Shari Lewis (1933-1998). The company began by focusing on health, psychology, and philosophy, with a strong emphasis on the Human Potential Movement, though over the years the company has expanded to include serious nonfiction books of all types. Putnam purchased the company in 1991, and the offices were moved to New York. Tarcher remained head of the company until early 1996, and Joel Fotinos was named Publisher later that year. Tarcher merged with sister imprint Perigee to form TarcherPerigee in 2015.
A total solar eclipse occurred in North America on February 26, 1979.
A total solar eclipse occurred on February 16, 1980. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. The path of totality crossed central Africa, southern India, and into China at sunset. The southern part of Mount Kilimanjaro, the highest mountain in Africa, also lies in the path of totality. Occurring only about 24 hours before perigee, the Moon's apparent diameter was larger.
An annular solar eclipse occurred on May 30, 1984. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Annularity was visible in Mexico, the United States, Azores Islands, Morocco and Algeria. It was the first annular solar eclipse visible in the US in 33 years. The moon's apparent diameter was near the average diameter because occurs 6.7 days after apogee and 7.8 days before perigee.
A total solar eclipse occurred at the Moon's ascending node of the orbit on June 11, 1983. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Occurring only 48 hours before perigee, the Moon's apparent diameter was larger.
A total solar eclipse occurred at the Moon’s ascending node of the orbit on Friday, July 31, 1981. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. The continental path of totality fell entirely within the Soviet Union, belonging to Georgia, Kazakhstan and Russia today. The southern part of Mount Elbrus, the highest mountain in Europe, also lies in the path of totality. Occurring only 3.8 days after perigee, the Moon's apparent diameter was larger. With a path width of 107.8 km, this total solar eclipse had an average path.
There will be a solar eclipse on July 16, 2186, which will be the longest total eclipse for thousands of years. The eclipse will pass over the southern Galápagos Islands, the northern tip of Ecuador, central Colombia, central Venezuela, and northern Guyana.
A partial solar eclipse occurred on January 25, 1982. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.
A partial solar eclipse occurred on July 20, 1982. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.
An annular solar eclipse occurred at the Moon's descending node of the orbit on February 4–5, 1981. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. This annular solar eclipse was large because the Moon covered 99.4% of the Sun, with a path width of only 25 km . It was visible in Australia, crossing over Tasmania and southern Stewart Island of New Zealand near sunrise on February 5th (Thursday), and ended at sunset over western South America on February 4th (Wednesday). Occurring only 4 days before perigee, the moon's apparent diameter was larger.
An annular solar eclipse occurred on August 10, 1980 centred over the Pacific Ocean. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Annularity was visible in Tabuaeran of Kiribati, Peru, Bolivia, northern Paraguay and Brazil. Occurring 5 days before apogee, the Moon's apaprent diameter was smaller. At greatest eclipse, the Sun was 79 degrees above horizon.

A supermoon is a full moon or a new moon that nearly coincides with perigee—the closest that the Moon comes to the Earth in its elliptic orbit—resulting in a slightly larger-than-usual apparent size of the lunar disk as viewed from Earth. The technical name is a perigee syzygy or a full Moon around perigee. The term supermoon is astrological in origin and has no precise astronomical definition.
