El lanzamiento más incierto de la NASA

Empiezan las pruebas del Ares, polémico sucesor de los ‘shuttle’

Casi 30 años después, la NASA va a poner a prueba un nuevo cohete para llevar humanos al espacio. Esta madrugada en EEUU, el Ares I-X, el cohete más alto del mundo, comenzará a rodar desde el hangar en que fue construido durante los últimos 10 meses hasta su rampa de lanzamiento en Cabo Cañaveral. El trayecto, de seis kilómetros y medio, durará siete horas. Si no surgen contratiempos, el prototipo del cohete Ares I, diseñado para reanudar las expediciones tripuladas a la Luna, se lanzará el 27 de octubre.

Observaciones astronómicas por toda España

Del 22 al 24 de octubre se celebran las Noches de Galileo

Durante los días 22, 23 y 24 de octubre decenas de astrónomos amateur tomarán las calles y plazas españolas para rendir homenaje a la figura de Galileo Galilei. Se trata de las Noches de Galileo, un celebración enmarcada en el Año Internacional de la Astronomía cuyo objetivo es mostrar al público lo que el astrónomo italiano observó por primera vez a través de su telescopio hace 400 años. Alrededor de 40 agrupaciones astronómicas españolas participarán a partir de mañana en esta serie de actividades, sujetas en parte a que las condiciones meteorológicas lo permitan. Consultar el programa aquí .

Además de las más de 80 observaciones astronómicas previstas, también se han organizado charlas y conferencias, talleres para aprender a usar un telescopio, acampadas, retransmisiones en directo de observaciones a través de Internet, sesiones de planetario…[]

ESA vodcast ‘Charting the Galaxy – from Hipparcos to Gaia’

‘In this sixth episode of the Science@ESA vodcast series Rebecca Barnes discovers the motions of the stars, learns how astronomers measure their distances and looks at the new European mission that will really get to grips with our place in the Universe.’

The Planck Mission: Looking Back To The Dawn Of Time

In the Science@ESA series Rebecca Barnes will take you on a journey of discovery into the rapidly evolving field of space astronomy and planetary exploration.

In this second episode Rebecca takes a close look at Planck – a European Space Agency mission built to detect radiation from the microwave portion of the electromagnetic spectrum. This mission will help find answers to some of the most important questions in modern science.

The Big Bang is the cosmological model of the initial conditions and subsequent development of the Universe that is supported by the most comprehensive and accurate explanations from current scientific evidence and observation.

As used by cosmologists, the term Big Bang generally refers to the idea that the Universe has expanded from a primordial hot and dense initial condition at some finite time in the past (currently estimated to have been approximately 13.7 billion years ago), and continues to expand to this day.
Planck was selected as the third Medium-Sized Mission (M3) of ESA’s Horizon 2000 Scientific Programme, and is today part of its Cosmic Vision Programme. It is designed to image the anisotropies of the Cosmic Background Radiation Field over the whole sky, with unprecedented sensitivity and angular resolution.

Planck will provide a major source of information relevant to several cosmological and astrophysical issues, such as testing theories of the early universe and the origin of cosmic structure.

Planck was launched on 14 May 2009 together with the Herschel satellite. After launch, Planck and Herschel separated and are now proceeding to different orbits around the second Lagrangian point of the Earth-Sun System.

NASA What’s Up for October 2009? Andromeda Galaxy

Ares I-X Rocket Rollout 20 October 2009

The Ares I-X rocket has moved Launch Pad 39B Kennedy Space Center Florida.

 

ARES 1X Rollout

For the first time in more than a quarter century, a new vehicle is sitting at Launch Pad 39B at NASA’s Kennedy Space Center in Florida. The Ares I-X flight test vehicle arrived at the pad atop of a giant crawler-transporter at approximately 7:45 a.m. EDT Tuesday.

The crawler-transporter left Kennedy’s Vehicle Assembly Building at 1:39 a.m., traveling less than 1 mph during the 4.2-mile journey. The rocket was secured on the launch pad at 9:17 a.m.

The vehicle is scheduled to launch at 8 a.m. on Oct. 27. This test flight of the Ares I-X rocket will provide NASA an early opportunity to test and prove hardware, models, facilities and ground operations associated with the Ares I launch vehicle.

Nasa nuevas imagenes del Hubble

‘A recent NASA/ESA Hubble Space Telescope image captures what appears to be one very bright and bizarre galaxy, but is actually the result of a pair of spiral galaxies, like our own Milky Way, smashing together at incredible speeds. This object was a target of Hubble’s and a handful of its “sibling” spacecraft as part of a massive comprehensive sky survey called GOALS.’

NASA | Earth Science Week: Keeping Up With Carbon

Semana de la Tierra en la NASA: El ciclo del carbono

“Keeping Up With Carbon” is the final episode in the six-part series “Tides of Change”, exploring amazing NASA ocean science to celebrate Earth Science Week 2009.

http://climate.nasa.gov/esw/

Carbon is all around us. This unique atom is the basic building block of life, and its compounds form solids, liquids, or gases. Carbon helps form the bodies of living organisms; it dissolves in the ocean; mixes in the atmosphere; and can be stored in the crust of the planet. A carbon atom could spend millions of years moving through this complex cycle. The ocean plays the most critical role in regulating Earths carbon balance, and understanding how the carbon cycle is changing is key to understanding Earths changing climate.

 

NASA Earth Science Week: Melting Ice, Rising Seas

Melting Ice, Rising Seas” is Episode 5 in the six-part series “Tides of Change”, exploring amazing NASA ocean science to celebrate Earth Science Week 2009.

Sea level rise is an indicator that our planet is warming. Much of the world’s population lives on or near the coast, and rising seas are something worth watching. Sea level can rise for two reasons, both linked to a warming planet. When ice on land, such as mountain glaciers or the ice sheets of Greenland or Antarctica, melt, that water contributes to sea level rise. And when our oceans get warmer – another indicator of climate change – the water expands, also making sea level higher. Using satellites, lasers, and radar in space, and dedicated researchers on the ground, NASA is studying the Earth’s ice and water to better understand how sea level rise might affect us all.

El viernes impacto del LCROSS en la luna

Este viernes, el cráter Cabeus A, situado cerca de la región polar Sur de la Luna, será el sitio más observado del Sistema Solar. Esto se debe a que esta huella -de unos 40 kilómetros de diámetro- impresa en la superficie de nuestro satélite natural por el impacto de un meteorito, se ha convertido en el sitio donde se estrellará la sonda espacial LCROSS, de la NASA y un trozo del cohete Centaur. La agencia busca analizar la columna de escombros que se elevará tras el impacto para ver si hay rastros de agua.

Aunque mucha gente no lo sepa, la Luna nos ha servido de diana antes. Efectivamente, son muchas las sondas y restos de vehículos espaciales que han sido deliberadamente estrellados contra la superficie del satélite. En julio de 1999, por ejemplo, impactó en la Luna la sonda Lunar Prospector (de la NASA) y en septiembre de 2006, la Smart-1 (de la Agencia Europea del Espacio), una vez que había concluido su misión. En general, estos impactos han servido par efectuar análisis sismográficos de nuestro satélite. Sin embargo, esta vez enviaremos un par trozos de chatarra que golpearán la Luna a 9000 kilómetros por hora para generar una columna de polvo Lunar.

El vehículo elegido para tener el “honor” de impactar contra la Luna es la parte superior del cohete Centaur utilizado para llevar la sonda espacial LCROSS, de la NASA, a la órbita de nuestro satélite natural. La sonda, que partió de la Tierra el pasado 18 de junio, atravesará la pluma de polvo y escombros que generará el choque del cohete, la analizará buscando indicios de agua, transmitirá los datos a la Tierra y poco después se estrellará también contra la Luna.
