Titolo: Lago Vostok: missioni di esplorazione

Avevo letto distrattamente che la Nasa stava preparando una missione per 
raggiungere il lago Vostok posto sotto l'antartide,
per simulare una possibile misione su Europa
Cercando maggiori info non trovo alcuna  conferma ufficiale;
Qualcuno di voi è informato su questo enigmatico lago Vostok?
Ciao

Ti ringrazio lo aveo già letto quel link, stavo cercando informazioni sullo 
stato della fantomatica missione NASA li sotto
in realtà sembra che non sia una voce confermata oppure la missione è in 
qualche maniera "riservata"

 non ti ricordi dove lo avevi "distrattamente"letto?
Su un libro national geographic letto in una sala d'attesa...

ma intendi questa roba ?

Questa era la base di partenza visti questi dati avrebbero dovuto 
organizzare una spedizione di esplorazione del lago con un robot
sommergibile, missione equivalente (a quanto si vorrebbe fare su europa)
E' Di questa missione che non trovo alcuna voce ufficiale   sull'avanzamento 
lavori
Probabilmente non c'è alcuna missione ufficiale tutto qui....

c'e' anche questa

non saprei dirti , forse è uno dei tanti progetti che si vorrebbero fare ma
chen on hanno ancora ne una data ne un "progetto" ufficiale
in parole povere i ricercatori sono li a sbavare per avere i fondi ...

"The large Jovian moon Europa may be hiding liquid water beneath its
frozen crust. Europa's frosty surface has intrigued scientists ever
since the Voyager spacecraft missions flew through the Jupiter system
in 1979. At -260° F, the moon's surface temperature could deep-freeze
an ocean over several million years, but it's possible that warmth
from a tidal tug of war with Jupiter and neighboring moons could be
keeping large parts of Europa's subsurface in a liquid state. Tidal
friction from Jupiter is also thought to be responsible for volcanic
activity on Europa's neighbor Io, and for a similar underground ocean
on Callisto. A number of prominent microbiologists along with NASA
planetary scientists strongly believe that Europa may harbor the best
bet for locating extraterrestrial life, despite the fact that its
surface is lethal to humans due to high velocity ion impact whipped up
in the Jovian gravitational field. This, plus the substantial travel
time, make the exploration of the purported subsurface ocean, and the
ultimate search for life therein, a job tailor made for a robot. The
mission NASA envisions involves a 3-stage spacecraft consisting of a
lander, a nuclear powered "cryobot" that melts its way down through up
to 10 kilometers of ice and which then deploys the third stage: an
autonomous "hydrobot" that propels itself into water depths that may
ultimately reach 50 kilometers in a totally uncharted world, uses a
hierarchical discrimination science payload to "sniff" out life
metabolites and environmental gradients favorable to life, locates,
verifies, and collects microbiological lifeforms, uses its own
just-created world map to return to the cryobot, and then "phones
home" with the data. In April 2004 NASA funded a 3-year project known
as DEPTHX, to build and test the prototype Europa third stage… the
hydrobot. If successful, DEPTHX will generate radical advances in
autonomous navigation and in the ability for silicon intelligence to
discriminate life. Bill Stone, who is leading a consortium of six
university and industry partners to develop DEPTHX, will speak on the
origins of the project, some of the more novel technical directions
being investigated, and the ultimate expedition to the world's deepest
cenote where the vehicle will be field tested in 2007.

Thx Eccolo! esiste allora;
è il progetto DEPTHX!
in questo link si parla espicitamente che l'indagine potrà prevedere 
l'esplorazione del Vostok
http://www.lpi.usra.edu/meetings/lpsc2005/pdf/2206.pdf
"In a later phase,
after the autonomous exploration system is fully tested,
the DEPTHX project will extend its terrestrial trials to
settings in the Antarctic ice, where conditions may
more closely approximate cracks or other openings in
Europa's ice. Other potential settings for testing (and
possible practical applications) may include unexplored
sub-aqueous environments like Lake Vostok,
other deep geothermal springs like Grand prismatic
Spring of Yellowstone, various marine environments,
and artificially created inhospitable environments (e.g.
the Berkeley acid mine drainage pit, Butte, MT, or
nuclear reactor cooling ponds."
