Sonda Voyager

Extracto de la nota.

En 1977, la NASA disparó al espacio a la sonda Voyager 1. Hoy, 34 años, 9 meses y 17 días después, es el aparato fabricado por el hombre que más lejos ha llegado en la historia, y estaría próximo a abandonar el sistema solar en cualquier momento. El año pasado, la NASA indicó que la sonda estaba en una nueva región hasta entonces desconocida del espacio llamada de “estancamiento”, que sería la última capa de la burbuja que rodea aj nuestro sistema solar.
“El análisis indica que el límite entre el espacio interestelar y la burbuja de partículas cargadas que el sol empuja alrededor de sí mismo probablemente mide entre 16.000 y 23.000 millones de kilómetros desde el sol, con una mejor estimación de aproximadamente 18.000 millones de kilómetros. Considerando que el Voyager está a alrededor de 18.000 millones de kilómetros de distancia, podría cruzar al espacio interestelar en cualquier momento”, explicó Tom Krimigis, investigador del Voyager.
Los nuevos cálculos se realizaron tomando datos de la sonda Cassini, que orbita Saturno, y que tiene sensores para captar átomos que vienen desde fuera de nuestro sistema solar. Los resultados fueron publicados en la revista Nature.

 Es importante que a traves de nuevas observaciones espaciales y utilizando toda la información disponible este realizando nuevos calculos para estas sondas viajeras.

Capitán Raymar : Harlock

Captain Harlock ( 宇宙海賊キャプテンハーロック , Uchū Kaizoku Kyaputen Hārokku , lit. Space Pirate Captain Harlock ) is a fictional character created by manga artist Leiji Matsumoto . Harlock is the archetypical romantic hero, a space pirate with an individualist philosophy of life. He is as noble as he is taciturn, rebellious, stoically fighting against totalitarian regimes, whether they be earthborn or alien. In his own words, he "fight[s] for no one's sake... only [...] for something deep in [his] heart". The character first appears in Adventures of a Honeybee . (1953) The first series featuring Harlock in the lead role is 1978's Space Pirate Captain Harlock . As with most of Matsumoto's works, continuity is not a crucial issue. An appearance of any particular version of the character does not necessarily connect to any previous or following versions, and the interconnectedness of the various series is a common subject of speculation among fans.

Warp 11

Cuando pense que todo sobre Star Trek, podria estar cubierto, me encontre con esta banda de lunaticos llamados Warp 11, y su Capitan Karl. Miren la opiniones en EEUU: "Warp 11 is one of the best bands in America, not since KISS has a band had this level of shtick, and an amazing sound backing it up." - Mark S. Allen Premiere Radio Networks "Warp 11 is a Trek band that has crossed over from fandom to mainstream music." - Tammy Oler Geek Monthly "This isn't a bunch of Trekkies who decided to rock, but rather it's a buncha rockers who dediced the world of Star Trek was ripe with rockin' potential.. Warp 11 doesn't let any joke get by.. they're so gloriously vulgar!" - Jerry Perry Alive & Kicking "Sactown's own Warp 11 are the bad boys at the Trekkie convention." - Justin Allen Sacramento News & Review "It's Dead, Jim - a typically ass-kicking release from the Warped ones." - A.L. Sirois Sci Fi Channe...

Free as in Freedom

Free as in Freedom interweaves biographical snapshots of GNU project founder Richard Stallman with the political, social and economic history of the free software movement. It examines Stallman's unique personality and how that personality has been at turns a driving force and a drawback in terms of the movement's overall success. Free as in Freedom examines one man's 20-year attempt to codify and communicate the ethics of 1970s era "hacking" culture in such a way that later generations might easily share and build upon the knowledge of their computing forebears. The book documents Stallman's personal evolution from teenage misfit to prescient adult hacker to political leader and examines how that evolution has shaped the free software movement. Like Alan Greenspan in the financial sector, Richard Stallman has assumed the role of tribal elder within the hacking community, a community that bills itself as anarchic and averse to central leadership or authority...
