Observaciones multicolores de fobias con las cámaras del módulo de aterrizaje vikingo: evidencia de una composición
Science (New York, N.Y.)
|January 6, 1978
Resumen
Phobosos es el nombre de Phobos.
Área de la Ciencia:
- Ciencias planetarias Ciencias planetarias.
- Astrogeología y Astrogeología.
- La espectroscopia es una técnica de espectroscopia.
Sus antecedentes:
- Fobos, una luna de Marte, tiene una composición de la superficie que no se entiende completamente.
- Estudios anteriores han proporcionado datos espectrales limitados para Phobos.
Objetivo del estudio:
- Para determinar la reflectividad de Fobos en la región espectral de 0,4 a 1,1 micrómetros.
- Para comparar las propiedades espectrales de Fobos con muestras de laboratorio para inferir su origen.
Principales métodos:
- Análisis de los datos de reflectividad de las imágenes de las cámaras de aterrizaje del Viking.
- Comparación de datos espectrales observados con espectros de laboratorio de condritas y basaltos carbonáceos.
Principales resultados:
- Phobos exhibe una curva de reflectividad plana entre 0,4 y 1,1 micrómetros.
- Se determinó que el albedo geométrico de Fobos es de 0,05 +/- 0,01.01.
- Los espectros observados se alinean con las condritas carbonáceas, no con los basaltos.
Conclusiones:
- Las características espectrales de Fobos son consistentes con el material de condrita carbonácea.
- Los hallazgos sugieren que Phobos puede ser un asteroide capturado en lugar de un satélite natural de Marte.

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...
01:21The Phosphorus Cycle
Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.
01:20Sulfur Assimilation
Sulfur is an essential element in biological systems, contributing to synthesizing key biomolecules, including amino acids such as cysteine and methionine, and cofactors such as coenzyme A and biotin. Microorganisms primarily assimilate sulfur as sulfate (SO₄²⁻) from the environment, which must undergo a series of biochemical transformations before it can be incorporated into cellular components. As sulfate is highly oxidized, it must undergo assimilatory sulfate reduction to become...
02:56The Fossil Record
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
01:02Flame Photometry: Overview
Flame photometry, also known as flame emission spectrometry, is a technique used for the qualitative and quantitative analysis of elements present in a sample using a flame as the source of excitation energy. The concept of flame photometry was realized in the early 1860s by Kirchhoff and Bunsen, who discovered that specific elements emit characteristic radiation when excited in flames. The first instrument developed for this purpose was used to measure sodium (Na) in plant ash using a Bunsen...
01:26Microbes and Methanogenesis
Methanogenesis is a critical microbial process in anaerobic ecosystems responsible for the biological production of methane, a potent greenhouse gas and valuable biofuel. This metabolic pathway is primarily facilitated by methanogenic archaea, which thrive in anoxic environments such as wetlands, sediments, and animal gastrointestinal tracts. The absence of oxygen in these habitats prevents aerobic respiration, thereby favoring alternative biochemical pathways for organic matter degradation.In...
