Resumen
El Imager for Mars Pathfinder (IMP) reveló una compleja superficie marciana formada por el agua, el viento y los impactos. El análisis identificó distintos tipos de roca y suelo, y observó delgadas nubes de hielo de agua azulado en el cielo antes del amanecer.

- Ciencias planetarias Ciencias planetarias.
- Geología Geología Geología.
- Ciencias de la atmósfera Ciencias atmosféricas.
Sus antecedentes:
- La superficie marciana exhibe complejas características geológicas.
- Las misiones anteriores han proporcionado datos limitados sobre la composición de la superficie y las condiciones atmosféricas.
Objetivo del estudio:
- Para analizar las características geológicas y la composición de la superficie de Marte utilizando el Imager for Mars Pathfinder (IMP).
- Para investigar los fenómenos atmosféricos, específicamente la formación de nubes, en el cielo marciano antes del amanecer.
Principales métodos:
- Análisis de imágenes de la superficie tomadas por el Imager for Mars Pathfinder (IMP).
- Análisis de la firma espectral de las rocas y suelos marcianos (440-1000 nm).
- Observación y análisis de imágenes IMP del cielo antes del amanecer.
Principales resultados:
- Identificó una compleja superficie marciana con crestas y valles modificados por procesos fluviales, eólicos y de impacto.
- Caracterizó tres tipos de roca distintos y cuatro clases de suelo basadas en firmas espectrales.

02:16Light Acquisition
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.
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.

01:29Kepler's Second 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. His first law states that all planets orbit the Sun in an elliptical orbit, with the Sun at one of the ellipse's foci. Therefore, the distance of a planet from the Sun varies throughout its revolution around the Sun.
While in an elliptical orbit, the total energy of the planet is conserved. Therefore, the planet slows down when it is at apogee and...

01:26Phase Contrast and Differential Interference Contrast Microscopy
Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

01:24X-ray Imaging
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
01:16Flame Photometry: Lab
In a flame photometer, when a solution like potassium chloride is aspirated into the flame, the solvent evaporates, leaving behind dehydrated salt. This salt dissociates into free gaseous atoms in their ground state. Some of these atoms absorb energy from the flame, leading to their excitation. The excited atoms return to the ground state, emitting photons at characteristic wavelengths. Because only electronic transitions are involved, the resulting emission lines are very narrow. The intensity...
