La misión clementina a la luna: una visión general científica
Science (New York, N.Y.)
|December 16, 1994
Resumen
La misión Clementine mapeó la geología y la topografía lunares utilizando casi dos millones de imágenes y datos de alcance láser. Esto proporcionó la primera vista global de la superficie de la Luna, revelando los tipos de roca y el grosor de la corteza.
Área de la Ciencia:
- Ciencias planetarias Ciencias planetarias.
- Geología Lunar Geología Lunar
- La geofísica es la geofísica.
Sus antecedentes:
- La composición de la superficie y la topografía de la Luna se entendieron incompletamente antes de la misión Clementine.
- Las investigaciones geológicas detalladas de las regiones polares y el lado lejano fueron limitadas.
Objetivo del estudio:
- Mapear globalmente los tipos de roca de la corteza lunar utilizando imágenes visibles e infrarrojas.
- Para llevar a cabo la primera investigación geológica detallada de las regiones polares y la cara oculta de la Luna.
- Para generar un mapa topográfico global de la Luna y determinar el grosor de la corteza lunar.
Principales métodos:
- Adquisición de casi dos millones de imágenes digitales en longitudes de onda visibles e infrarrojas por la nave espacial Clementine durante 71 días en órbita lunar.
- Utilizando mediciones de alcance láser para determinar la topografía lunar.
- Derivando el grosor de la corteza lunar a partir de datos de topografía y gravedad.
Principales resultados:
- Ahora es posible el mapeo global de los tipos de rocas de la corteza lunar.
- Se han obtenido conocimientos geológicos detallados sobre las regiones polares lunares y el lado lejano lunar.
- Se creó el primer mapa topográfico global de la Luna, que incluía mediciones de antiguas cuencas de impacto y un mapa derivado del grosor de la corteza lunar.
Conclusiones:
- La misión Clementine proporcionó conjuntos de datos globales sin precedentes para estudios geológicos y topográficos lunares.
- Estos datos permiten una comprensión completa de la composición de la superficie de la Luna, las características geológicas y la estructura interna.

01:18Projectile Motion: Example
The theory of projectile motion is very useful for players of several sports to improve their performance. For example, a javelin thrower needs to throw their javelin in such a way that it travels as far as possible. The javelin thrower takes a short run-up to increase the initial speed of the javelin. The range of a projectile is at its maximum at a 45° angle so javelin throwers try to angle their throw as close to 45° as possible.

01:16Circular Orbits and Critical Velocity for Satellites
The Moon orbits around the Earth. In turn, the Earth (and other planets) orbit the Sun. The space directly above our atmosphere is filled with artificial satellites in orbit. One can examine the circular orbit, the simplest kind of orbit, to understand the relationship between the speed and the period of planets and satellites with respect to their positions and the bodies that they orbit.

01:10Kepler's First Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. He formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe.
Polish astronomer Nikolaus Copernicus put forth a theory that stated a heliocentric model for the solar system. According to this heliocentric theory, all the planets, including Earth, orbit the Sun in circular orbits.

01:18Kepler's Third Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. In 1909, he formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe. However, in 1918, he published his third law of planetary motion, which gives a precise mathematical relationship between a planet's average distance from the Sun and the amount of time it takes to revolve around the Sun. It...
01:26Impact: Problem Solving
In an experiment conducted during a Mars mission, a rover propels a projectile with an initial velocity, and the projectile rebounds after colliding with the Martian surface. To ascertain the maximum height attained by the projectile after this collision, the known restitution coefficient and acceleration due to gravity are employed.
By designating the launch point as the origin and utilizing kinematic equations, the vertical component of the projectile's velocity at the point of impact is...

01:23Trigonometric Substitution
Trigonometric substitution is a technique used to simplify integrals that contain square root expressions involving quadratic forms. It is particularly effective when the integrand includes terms resembling those found in standard geometric equations, such as circles or ellipses.Molniya satellites follow highly elliptical orbits, repeatedly sweeping out the same regions of space as they revolve around Earth. To estimate the area enclosed by such an orbit, the path is modeled as an ellipse...
