Chief Executive Officer Elon Musk said late on Monday that the braking issue on Tesla Inc’s Model 3 sedan, pointed out by Consumer Reports, can be fixed with a firmware update which the electric car maker will be rolling out in a few days. “With further refinement, we can improve braking distance beyond initial specs. Tesla won’t stop until Model 3 has better braking than any remotely comparable car,” Musk wrote in a tweet. Influential U.S.

It's becoming increasingly common to see a self-driving car on the road these days, but a large portion of Americans are still opposed to or hesitant about the concept. According to a new Gallup poll more than half of Americans expect autonomous cars to be commonly used within 10 years. Only a fourth of the poll participants expect it to take longer than 16 years.Western states were more likely than any other US region to believe it'll happen within the decade.

Gaia crea el mapa más preciso de la Vía Láctea

2018-05-17    0 views
Hemos ido hasta el Observatorio de París, en pleno corazón de la capital francesa.

Vamos a entrevistar a astrónomos que trabajan en la misión Gaia , que ha estado observando más de mil millones de estrellas alrededor de nuestra galaxia, tratando de resolver algunos de los misterios de la Vía Láctea".

El astrónomo francés Frédéric Arenou es uno de los muchos científicos que trabajan con los datos ofrecidos por el telescopio espacial Gaia.

La misión acaba de publicar el catálogo de estrellas más importante jamás registrado. La esperanza es que sepamos más acerca de la Vía Láctea.

Frédéric Arenou comenta:

"Esta es nuestra galaxia, la Vía Láctea. Cien mil años luz de extensión, y estamos a unos 26 mil años luz del centro aunque no lo tenemos del todo claro, esto es solo una impresión. No sabemos el número de brazos de nuestra galaxia, o dónde se forman las estrellas. Gaia nos lo dirá."

Se espera que Gaia nos diga muchas cosas.

El telescopio espacial de la ESA ha realizado mediciones de alta precisión de 1.700 millones de estrellas.

Son 10.000 veces más mediciones que en la anterior misión de la ESA llamada Hipparcos.

Es un momento crucial en laastronomía.

Frédéric Arenou comenta:

"De repente tenemos una enorme muestra de objetos de los que conocemos su distancia, y por lo tanto su luminosidad. A partir de su luminosidad podemos deducir sus propiedades físicas que ya las habíamos intentado conocer antes. Y así de fácil, obtenemos una respuesta".

Durante mucho tiempo el objetivo de los astrónomos ha sido obtener este catálogo.

Todo comenzó aquí, en el Observatorio de París en 1887, con un proyecto llamado la ‘Carte du Ciel’, que produjo estos complicados mapas estelares.

Hoy en día, los astrónomos tienen un telescopio de mil millones de píxeles girando sigilosamente en un lugar del espacio.

Chantal Panem, jefe de proyecto de Gaia, comenta:

" Gaia está a 1,5 millones de kilómetros de la Tierra , y está alineada sobre el eje: Sol-Tierra-Gaia. Gira sobre sí mismo cada 6 horas, y es capaz de observar toda la galaxia, así que en unos cuantos años tendremos un mapa completo del cielo".

Hay tres instrumentos: un astrómetro, que permite medir las posiciones. Un fotómetro, que se utiliza para medir los colores, y un espectrómetro, que nos permite medir la velocidad radial - la velocidad radial es la velocidad a la que las estrellas se alejan o se acercan a nosotros".

Este es el resultado, como se ve nuestra galaxia desde el espacio. La mejor imagen que hemos tenido de la Vía Láctea.

El astrónomo finlandés Timo Prusti dirige el equipo científico Gaia de la ESA.


"Gaia utiliza las medidas reales. Estamos midiendo el número de estrellas que estamos observando en diferentes partes del cielo. ¿Qué es lo que vemos? Vemos una estructura aplastada, esa es nuestra Vía Láctea. Ese es el disco de la Vía Láctea. Tenemos algunas manchas oscuras encima, y ¿qué significa esto? Significa que allí vemos menos estrellas. Hay más estrellas, pero hay polvo frente a ellas, y por eso no las vemos".

Los datos de Gaia también han sido animados en una pantalla que ofrece una vista única de la Vía Láctea. Vemos cómo las estrellas se mueven a través del espacio y el tiempo.

Mirando esta animación, y analizando los datos, los astrónomos son capaces de mirar en la oscuridad cosas que no se imaginaban.

Timo Prusti recalca:

"Creemos que nuestra galaxia, la Vía Láctea es un disco, con una estructura en espiral y todo gira alrededor.

Lo que vemos con los datos de Gaia es que las estrellas que están un poco más lejos del Sol, en realidad no se comportan como pensamos. Están perturbadas, algo ha perturbado a la Vía Láctea. Todavía no sabemos qué. Pero seguro que se van a llevar a cabo muchos estudios acerca de esto.

Tener la habilidad de estudiar la historia y el futuro de nuestra galaxia desde dentro de la Vía Láctea, promete muchos descubrimientos en todas las áreas de la astronomía.

François Mignard, uno de los fundadores de la misión Gaia, espera que los nuevos datos sobre los 1.700 millones de estrellas ayu

Two astronauts, Drew Feustel and Ricky Arnold of NASA, carried out the fifth spacewalk of 2018 on May 16, swapping out cooling components on the exterior of the International Space Station.
According to information provided by NASA, the astronauts were fixing the station’s pump flow control subassembly, which is one of the instruments used to regulate the station’s flow of ammonia coolant. This coolant is used to maintain temperatures for the station’s delicate hardware.
This footage shows the astronauts on their spacewalk.

NASA has decided it wants a birds-eye view of Mars the next time it sends a craft there. The Mars Helicopter, a tiny remote-control dual-rotor drone, will make the trip to the red planet stowed in the belly pan of the Mars 2020 Rover.
Once on the surface, the six-wheeled rover will deploy the small chopper in a suitable location. This will allow it to charge its batteries and run through a variety of pre-flight tests before making history in the thin Martin atmosphere.

Black Panther’s Vibranium Tech Coming Soon To A Real World Near You

2018-05-11    0 views
According to a report by ScreenRant, some real life materials are bringing the Black Panther's Vibranium technology from the Marvel Cinematic Universe to the real world. While human beings haven't yet discovered a magical metal with the ability to absorb and redistribute energy, scientists have been able to develop several materials that share some incredible properties with the make-believe Marvel metal. Kevlar, while a formidable armor, lacks the flexibility of the Black Panther's suit. 'Dragon Silk,' currently being developed by the U.S. Army, is significantly more flexible than Kevlar, but only 67% as strong. However, Graphene is a semi-metal stronger than both Kevlar and steel that can redistribute impacts as “vibrations” throughout the material, which is comprised of diamond-based carbon bonds.
