A space tower is a tower that would reach outer space.To avoid an immediate need for a vehicle launched at orbital velocity to raise its perigee, a tower would have to extend above the edge of space (above the 100 km Kármán line), [26] but a far lower tower height could reduce atmospheric drag losses during ascent.
Apollo (spacecraft) The Apollo spacecraft was composed of three parts designed to accomplish the American Apollo program 's goal of landing astronauts on the Moon by the end of the 1960s and returning them safely to Earth. The expendable (single-use) spacecraft consisted of a combined command and service module (CSM) and an Apollo Lunar Module ...
Apollo 13 (April 11–17, 1970) was the seventh crewed mission in the Apollo space program and the third meant to land on the Moon. The craft was launched from Kennedy Space Center on April 11, 1970, but the lunar landing was aborted after an oxygen tank in the service module (SM) ruptured two days into the mission, disabling its electrical and life-support system.
Moonlight tower. A moonlight tower or moontower is a lighting structure designed to illuminate areas of a town or city at night. Only the collection of towers in Austin, Texas, have been termed historically "moonlight towers," a term that dates to the mid-20th century. The light from the towers was compared to moonlight, after they were ...
The concept of a Tsiolkovsky tower combined with a classic space elevator cable (reaching above the level of GEO) has been suggested. [6] Other ideas use very tall compressive towers to reduce the demands on launch vehicles. [97] The vehicle is "elevated" up the tower, which may extend as high as above the atmosphere, and is launched from the ...
Moonrise and moonset are times when the upper limb of the Moon appears above the horizon and disappears below it, respectively. The exact times depend on the lunar phase and declination, as well as the observer's location. As viewed from outside the polar circles, the Moon, like all other celestial objects outside the circumpolar circle, rises ...
Apollo 10 (May 18–26, 1969) was the fourth human spaceflight in the United States' Apollo program and the second to orbit the Moon. NASA, the mission's operator, described it as a "dress rehearsal" for the first Moon landing (Apollo 11, two months later [ 4 ]). It was designated an "F" mission, intended to test all spacecraft components and ...
Each display included Moon dust from Apollo 11 and flags, including one of the Soviet Union, taken along by Apollo 11. The rice-sized particles were four small pieces of Moon soil weighing about 50 mg and were enveloped in a clear acrylic button about as big as a United States half-dollar coin. This acrylic button magnified the grains of lunar ...
