La NASA lanza cinco satélites para investigar las auroras boreales

Bien me alegra leer noticias de paises que invierten en desarrollo de investigacion sobre todo cuando este desarrollo viene de US unos de los paises que ultimamente se centro mas en el mundo belico que cultural

¡Qué bien, por fin una noticia que no hable de guerras, asesinatos, desastres, parricidios, etc! Hoy me saco la lotería (si tuviese para comprar el billete, claro..).

Bromas aparte,

1. Esto de las auroras boreales + tormentas me recuerda al antiguo mito de los Dioses- Hermanos gemelos de la cosmología hindú llamados Mitra y Varuna, que siempre estaban juntos: Mitra era el sol de la aurora (patrón de los tratos, juramentos y promesas, nada que ver con el Mithra persa ni con el culto al toro) y Varuna el de las tormentas, las aguas y el aire revuelto... Parece que las mitologías tienen siempre alguna pizca de verdad de forma intuitiva...


2. Si el magnetismo produce calor, el calor puede producir movimiento y por tanto energía: ¿Tal vez se averigüen formas más ecológicas de aprovechamiento y fabricación de energía que no contamine y utilice procesos ya existentes en la naturaleza?

3. Seguro que al final encuentran una tercera teoría que puede ser: o bien una mezcla de las dos, o bien otra que no tenga nada que ver...

En fin, saludos.

En el momento que mas o menos nos puedan explicar el misterio de algo pierde parte o todo el encantamiento y misterio ,no quiero saber el como ni el porque solo verlas y si no puedo verlas al menos intuirlas.

Y mientras muere la gente de hambre.

La muerte por hambre de muchas personas no es debido a la investigación espacial, sino a la falta de humanidad y justicia en el mundo, y, por supuesto, al capitalismo que sólo valora el dinero y no la vida (salvo que le de beneficios).

si no saben que son y como se hacen las auroras boreales estos de la ciencia oficial de la nasa judia
¿como saben como funciona el Sol y el calentamiento global por el simplon efecto invernadero que no tiene secretos ni para los pastores o los jardineros?
NO SERAN TODOS UNOS MENTIROSOS DE TOMO Y LOMO COMO EL AL GORE

Eso de que no lo saben lo dirás tú, Jesulin. Todo el mundo sabe cómo se forma una aurora boreal: las partículas del viento solar impactan contra la atmósfera terrestres quedando algunas de ellas atrapadas por el magnetismo y produciendo un efecto luminiscente.

¡Anda! ¡no era un milagro, entonces!

:D

pero de que particulas hablas?
porque si son neutrones con tanta cantidad por segundo no quedaria ya nadie vivo sobre la tierra
vamos ni las ratas de laboratorio
y si fuesen electrones no podriamos tener ninguna comunicacion por radio seria y nitida y si son fotones se darian tambien en cualquier sitio
VOSOTROS SOIS COMO LOS CURAS catolicos que con dos palabras magicas os creis que ya sabeis todo y no sabeis nada mas que engañar a la gente y no teneis ni puta idea de la materia

seras de esos catedraticos que cobran por no hacer nada y se apuntan a todos los megaproyectos que duran mas que su vida laboral para chupar del bote del dienero publico sin ninguna responsabilidad hasta que se mueran
VALENTES VIVIDORES
o lo peor eres un tonto de baba que te cres que sabes todo con un titulin que no te sirve ni para limpiarte el culo?

SE OLVIDARON DE PONER LO DE LOS CIENTIFICOS CANADIENSES, ya que participa la universidad de Calgary provincia de Alberta, en Canadá.

Rocket blasts off on mission to study northern lights
Last Updated: Saturday, February 17, 2007 | 11:23 PM ET

A rocket launched from Florida on Saturday, carrying five satellites that Canadian and U.S. scientists hope will help them unveil the science behind the substorms that cause the northern lights.

The rocket — part of the THEMIS project, a joint venture of NASA and the Canadian Space Agency — blasted off at 6:01 ET from the Cape Canaveral Air Force Station.

Scientists believe geomagnetic substorms in the Earth's atmosphere periodically intensify the spectacular light shows seen in the northern lights.
(CBC) NASA delayed the launch twice earlier in the week because of bad weather.

Scientists hope the $200 million US project will help them figure out what causes the substorms behind the shimmering northern lights, or aurora borealis, seen in northern skies.

On Saturday, one of the Canadian scientists said the launch was special event because much time and energy has gone into the project.

"This is huge," Brian Jackal, a physicist at the University of Calgary. "This is four years of our life which could have just been flushed away if something had gone wrong."

The project includes contributions from scientists from the University of Alberta and University of Calgary.

The substorms behind the northern lights can wreak havoc on communication satellites, shut down power grids and send high levels of radiation down on astronausts doing spacewalks.

The satellites, as part of the project, are being sent into orbit to monitor the interaction between charged particles expelled by the sun and the Earth's magnetic field.

When these particles interact with the magnetic field, they occasionally release energy near the polar regions in aurora substorms.

The released electrons interact with molecules in the atmosphere and appear in the night sky as the spectacular displays of the northern lights.

Involves 20 observatories, mostly in Canada
In addition to the satellites, 20 ground-based observatories, the majority located in Canada, will take digital images and monitor magnetic signatures from the substorms to record the auroras.

Jackal said the project, using images from the observatories and information from the satellites, is the most extensive study yet of the northern lights.

"This will be really interesting," he said Friday before the launch.

"It's unfortunate that we don't have a camera up there to keep an eye on things, but actually spinning five satellites out from a single launch vehicle is, I think, a new one.

"I don't think anyone's actually done this before, so that's going to be incredibly tense until they get the first signals back from outer space saying they're going to be okay."

Mission could help prevent problems
Alan Dyer, an astronomer in Calgary, said the project is important because it help scientists better understand the northern lights.

"It's a very unique mission to really study the mechanism of how the energy from the sun drives the northern lights, at least that's where it started, how that energy gets to the earth and fires up the northern lights," he said.

If scientists can unravel what triggers the substorms, then it could help them avoid potential problems, he said.

"We'd have a more distant early warning system. We'd know when this bad space weather is coming and what its effect might be," he said.

Scientists plan to begin receiving data from the probes in about two months and continue receiving information for many years.
