"If we could discover an ocean on Europa ... unbelievable!"
-- Dan Goldin, NASA Administrator, 1995

Shortly after the first NASA unmanned Voyager mission to Jupiter,
in March, 1979, Richard C. Hoagland published in Star & Sky magazine
a radical new theory -- regarding implications stemming from Voyager's
historic fly-by and data return from one of the "Galilean moons":
Europa.
Hoagland proposed that a planet-wide ocean still exists under the tens-of-miles-thick
sulphur-tinged ice now completely covering Europa. Further, that in that
extremely ancient ocean -- the only other planetary "near-by"
liquid water that may have persisted from the beginnings of the solar
system (other than on Earth)--
Life may have once originated ... an alien type of life
that -- because of the present uniqueness of Europa in the entire solar
system -- currently might still exist ...
At the time, Hoagland's theory encountered overwhelming
opposition from almost everyone at NASA, official and/or scientist ...
except for two significant exceptions: inventor of the communications
satellite, famed science and science fiction writer ("2001: A Space
Odyssey"), Arthur C. Clark; and, Dr. Robert Jastrow -- one of the
founders of NASA, and former Director of its Goddard Institute for Space
Studies. Based on Hoagland's startling theory, Clark two years later would
create a sequel to his most famous work ("2010: Odyssey Two"
-- after long claiming that such a follow-on was "impossible").
This would then be followed by a movie sequel (co-written and directed
by Peter Hyams) of the same name.
In the acknowledgments to "2010," Clark would write:
"The fascinating idea that there might be life on Europa, beneath
ice-covered oceans kept liquid by the same Jovian tidal forces that heat
Io, was first proposed by Richard C. Hoagland in the magazine Star &
Sky ( The Europa Enigma,' January, 1980). This quite brilliant concept
has been taken seriously by a number of astronomers (notably NASA's Institute
of Space Studies, Dr. Robert Jastrow), and may provide one of the best
motives for the projected GALILEO Mission..."
NASA's long-awaited unmanned GALILEO follow-on to Voyager -- consisting
of a separable instrumented "probe" (designed to actually plummet
into the huge Jovian atmosphere and report back its findings), and a much
longer-lived "orbiter" loaded with cameras and other sensors
(for close-up surveys of the planet and its unique space environment,
including the "Galilean moons") -- finally reached Jupiter on
December 7, 1995. The probe successfully streaked into Jupiter's crushing
atmosphere that afternoon, sending back 54 minutes of invaluable data
as it fell ... before the rising temperatures and pressures silenced it
forever; meanwhile, the Orbiter successfully fired its own retrorockets
-- becoming the second manmade object to be forever captured by the giant
planet Jupiter.
In a few short months, after completing its first elongated swing around
the largest of known planets, the Orbiter portion of the GALILEO spacecraft
will have an opportunity to turn its wide variety of sensors for the first
time on Europa -- only one of the many Jupiter "Galilean moon"
encounters planned for the next two-years.
And, in an astonishing reversal of their previous opinions,
NASA's entire Galileo team (if not all of NASA itself) is now on record
as "eagerly awaiting confirmation of the existence of Europa's planet-wide,
ice-covered ocean via GALILEO information" -- if not what may lurk
below ... Included in this vocal outpouring of "new Europa interest"
is NASA's present Administrator, Dan Goldin (see above).
At the University of Washington (Seattle), a team of oceanographers
is even now busily creating (for an official NASA mission proposal) a
full-scale, unmanned robotic expedition to Europa -- to follow GALILEO.
The idea: to remotely explore Europa's oceans from the Earth ... to actively
seek out "the new life forms" that Hoagland first proposed,
and Arthur Clarke then made seem so real.
Remarkable, totally unacknowledged amid all this new interest
in "Europa"-- by either NASA, the GALILEO scientists, or the
busy oceanographers at the University of Washington -- is the originator
of this remarkable idea, himself ...
Here, then, is Hoagland's original, unedited, highly controversial
1980 STAR & SKY "Europa Proposal" -- even as an official
NASA mission, 16 years after it was written -- clandestinely explores
its implications. Enjoy.
