LA AGENCIA ESPACIAL EUROPEA (ESA) REVELA EL MAPA MEJOR CONCEBIDO DE LA TIERRA

ESA unveils latest map of world’s land cover
 
ESA’s 2009 global land cover map
 

21 December 2010
ESA’s 2009 global land cover map has been released and is now available to the public online from the ‘GlobCover’ website. GlobCover 2009 proves the sharpest possible global land cover map can be created within a year.
 
The map was produced using 12 months of data from Envisat’s Medium Resolution Imaging Spectrometer at a resolution of 300 m.
ESA and Belgium’s Université catholique de Louvain created the map using software developed by Medias France and Germany’s Brockmann Consult on data collected from 1 January to 31 December 2009. GlobCover 2009 was generated within a year of acquiring the final satellite data.
The map’s legend uses the UN Food and Agriculture Organisation’s Land Cover Classification System.
Some 8000 people have downloaded the previous version, GlobCover 2005. These maps are useful for studying the effects of climate change, conserving biodiversity and managing natural resources.

ESTACION ESPACIAL INTERNACIONAL - EXPERIMENTOS LOS DIAS 27 28 Y 29 DE DICIEMBRE DE 2010

Los astronautas a bordo de la Estación Espacial Internacional llevarán a cabo varios experimentos con los radios a bordo,   los días 27, 28 y 29 de diciembre de 2010.

El experimento llamado "ET sombra"  consiste en enviar señales de radio a una frecuencia de 145.800 y 145.825. Estas señales de radio son recibidas por los radioaficionados entierra y grabado por ellos. Estos audios recibidos deben ser enviados a los siguientes e-mail:

shadow@tsniimash.ru
vastra@mail.ru
Junto con el audio,  los radio aficionados deberán enviar todos sus datos como:

Nombre: Indicativo: Dirección: Equipo utilizado: Antena: Situación Geográfica: Hora UTC Recibido: Foto de la foto de la estación o personales
El objetivo de este experimento es la observación de las señales de radio reflejadas por la atmósfera en diferentes localizaciones geográficas y el plasma en el espacio.
Los astronautas a bordo de inyectan una nube de plasma en el espacio y al mismo tiempo envían señales de baliza en la banda VHF para ser recibido por los radioaficionados enla tierra.. Debido a la refracción y la dispersión de las señales en las regiones de sombra la nube de plasma aparecerá al lado del satélite. Cuando el audio subido por aficionados son analizados por los controladores de tierra que se sabe que los puntos en las señales recibidas sufren refracción y no se han recibido provocando una sombra sobre un punto particular de la recepción de la señal.
Estas experiencias servirán para desarrollar nuevos cohetes propulsores que le ayudarán en el viaje espacial en el futuro. También ayudan a los conductores del futuro para desarrollar nuevos equipos de radio que no sufriría los efectos de la refracción o la interferencia con los cortes producidos por nubes en las comunicaciones enviadas por los propulsores de plasma a bordo de la nave espacial.

BBQ EN INGLATERRA PARA LOS AFICIONADOS A LOS 6 METROS EL SABADO 6 DE AGOSTO DE 2011

G3WOS's 2011 6M BBQ
Hi Manuel, After the great success of the previous BBQs, I am thinking of holding a 6m BBQ (if there is sufficient interest) on Saturday 6th August 2011 in Farnborough, Hampshire UK - so make a note in your diary!
Take a look at the 2005 BBQ web site. As we have always had a good number of non-UK 6m hams attend, I am sending this now so that you can plan your summer around the event by visiting the UK!
[Click on the picture for the GIANT version].
There will be plenty of food and drink, lots of 6m guys to talk to and argue with and XYLs are positively encouraged! I hope that we will see an even better turn out of non-UK 6m enthusiasts. For those wanting to stay over on Friday night, we will get everyone into the same hotel (The Falcon as in 2007) and organise another great 6m dinner for the Friday evening.

There will be several interesting talks to help pass the long hot summer day...

The cost of the BBQ is not yet known but will be around 30 UK POnds and will need to be paid in advance of the event.
I know it's a long way off, but if you are interested in attending PLEASE send me an email. If I don't don't hear from you I could assume there is no interest and cancel as I had to do in 2010!73 Chris G3WOS - chris@gare.co.uk

26 AÑOS DE VIDA Y EL OSCAR 11 CONTINUA ENVIANDO SEÑALES A TIERRA - INFORMACION DEL COLEGA MAURICIO BERALDO PY4MAB EN EL GRUPO ISS FAN CLUB DE BRASIL

De: py4mab
> Assunto: [ISSFANCLUBEBRASIL] Satelite Oscar 11 continua ativo após 26 anos
> Para: ISSFANCLUBEBRASIL@yahoogrupos.com.br
> Data: Quinta-feira, 2 de Dezembro de 2010, 15:10
>
>
> O satélite Oscar 11 esta completando 26 anos em órbita e continua enviando sinais para a Terra.
>
> No período de 29 de outubro a 30 de novembro de 2010 estações de todo o mundo receberam sinais do satélite. O satélite permaneceu ativo por esse período porque passou por um grande período de iluminação proporcionada pelo Sol. Um novo período de iluminação esta para iniciar no dia 10 de dezembro de 2010 e possivelmente o satélite voltará a ativa.
>
> A maioria dos sinais recebidos por Radioamadores em Terra foram sinais fracos indicando a baixa capacidade das baterias do satélite. O relógio a bordo do Oscar 11 esta muito estável ganhando oito segundos em novembro. Esse comportamento do relógio mostra que o satélite esta funcionando da mesma forma que há 26 anos atrás.
>
> O satélite funcionando nos períodos de eclipse e a estabilidade do relógio sugerem que alguma parte do sistema pode ter falhado recentemente, (circuito aberto), reduzindo assim o consumo de energia global do sistema e permite que mais energia seja armazenada pelo satélite nos períodos de eclipse.
>
> Quando foi coletado os sinais de telemetria do Oscar 11 os controladores do satélite observaram uma fuga inexplicável de energia mas essa falha já não acontece recentemente.
>
> Os controladores do satélite Oscar 11 pedem a todos os radioamadores que ajudem na recepção dos sinais e toda recepção pode ser postada nesta pagina abaixo:
>
> http://oscar.dcarr.org/index.php
>
> As freqüências do Oscar 11 são:
>
> Sinais do Beacon
> VHF 145.826 MHz.  AFSK FM  ASCII Telemetria
> UHF 435.025 MHz.  OFF
> S-band 2401.5 MHz. OFF
