Asunto:[mysteryplanet] FRACASA estripitosamente Experimento en Polo Norte de Marte - A. Araya

Hi...

      Yo sin ser Cientifico se que si voy al Polo Norte de cualquier Planeta es obvio que la tierra estara mojada o humeda al menos y por lo tanto estara como barro, pero, la NASA que tiene 700 Cientificos no lo sabe al parecer, ya que le dejo unos orificios demasiado pequenos al Horno de quemazon de tierra en que iban aextraerse o producirse los gases para ser analizados y asi lo muestra la Foto de la BBC, en que la tierra marciana se ve acumulada pero NO PUDO PASAR POR LOS PEQUENOS AGUJEROS...es decir, al parecer, no se hicieron pruebas con tierra humeda ni nada por el estilo, sino que se envio la Nave a pasearse a Marte - sin saberlo - es decir UN ESTRIPITOSO Fracaso de experimento - logicamente con 80 % de probabilidad de fracaso dado por seguro...Mien que extrano AAAAH..?

Aca la informacion de la BBC...

Martian soil frustrates Phoenix

Soil sample (Nasa)

Images clearly show the soil sample covering the entrance to the oven

Scientists working on Nasa's Phoenix lander are trying to work out why a soil sample dropped on to an instrument bay was not registered.

Images sent back from Mars clearly show the sample lying across a screen protecting the opening to a tiny oven.

But it seems the soil may have been too lumpy to pass through into the Thermal and Evolved-Gas Analyzer.

                    ************************

Los científicos que trabajan en la NASA Phoenix aterrizaje están tratando de determinar por qué una muestra de suelo soltada en un instrumento para ser usado no estaba registrado/reconocido.
Las imágenes enviadas desde Marte muestran claramente la muestra se extiende a través de una pantalla de protección de la apertura de un pequeño horno.
Pero parece que el suelo puede haber sido demasiado desigual para pasar a través/adentro del Analizador Térmico y  de Gas evolucionado/producido.

                                 ***************

The oven would have baked the soil to gain some insights into its possible water content and mineral make-up.

The sample was the first delivered to Phoenix's onboard laboratory by the 2.4m-long robot arm.

Until this time, the arm had merely been practising its digging technique.

The screen which covers the entrance to the analyzer is designed to let through only particles that are smaller than one millimetre, to stop a funnel leading to the tiny oven becoming clogged with larger fragments.

Polygon shape on ground (Nasa)

Polygon patterns are similar to those in permafrost regions on Earth

But an infrared beam crossing the pathway failed to register any material falling through the funnel, suggesting none of the sample material made it into the analyzer.

Scientists and engineers on the Phoenix mission team are now working through ideas on what to do next.

"I think it's the cloddiness of the soil and not having enough fine granular material," said Ray Arvidson, of Washington University in St Louis.

"In the future, we may prepare the soil by pushing down on the surface with the arm before scooping up the material to break it up, then sprinkle a smaller amount over the door," he explained.

Phoenix landed on Mars' northern plains on 25 May. It has sent back pictures of a flat, rust-coloured landscape which is marked by polygonal shapes in the ground.

Scientists think these polygonal features are the result of large quantities of water-ice expanding and contracting just below the dusty surface.

Phoenix will spend the next three months investigating its landing location for signs that life could ever have found the conditions there habitable.
