From Planets to Silicon Chips |
The search for life in our universe has been an outward journey for the most part. However, life is being defined on many different levels of complexity and our understanding of possible life-forms is expanding. The following resources will make all of this apparent as you examine the process of life from planets to silicon chips.

This is
the
STARTING
POINT
for a voyage of discovery
that only "The
Web" can supply. The
excitement is almost palpable as we surf the Solar System
and Universe in search of adventure. Read and learn as much
as you can. Mars will be our second home one
day. Mars is the
most Earth-like
other world
known, and with the two planets on the verge of their
closest approach in recorded history, it's time for the
planets to weigh in. In this tale of the tape, we present
the most pertinent and interesting facts that compare and
contrast the two very different worlds. The
Mars
Exploration
site operated by NASA has links to any pertinent information
concerning the Red Planet. The
Mars
Global Surveyor
has been and continues to be one of NASA's biggest success
stories. With it camera from Malin Scientific sending back
images daily, the Surveyor produces the most relavant data
of any of the mission robots that have been depolyed thus
far. Here's the NASA
site that is following the current Mars
Odyssey Mission.
Examine the latest data and pictures as the orbiter studies
the Martian surface for its chemical composition, the
possibility of subsurface water and measures the radiation
levels. Dr. Charles Elachi, director of
the National Aeronauticsand Space Administration's (NASA
(news
- web
sites)) Jet
Propulsion Lab, said final preparations were underway with
one 'exploration rover' arriving at Cape Canaveral this week
and the second due in three weeks. He said the rovers, which
are the size of an office desk, were set to be launched on
May 30 and June 25, piggy-backing on two rockets then
parachuting down to Mars in January in an air-bag cushioned
landing. "What a night," said Steve
Squyres, Principal Investigator for Spirit from Cornell
University. "Spirit has shown us her new home, Gusev Crater.
It's a glorious place
a wonderful place from a science
perspective," he said in a midnight press event at JPL.
NASA's twin robot geologists,
the Mars Exploration Rovers, launched toward Mars on June 10
and July 7, 2003, in search of answers about the history of
water on Mars. Primary among the mission's
scientific goals is to search for and characterize a wide
range of rocks and soils that hold clues to past water
activity on Mars. The spacecraft have landed on sites on
opposite sides of Mars that appear to have been affected by
liquid water in the past. The landing sites are at Gusev
Crater, a possible former lake in a giant impact crater, and
Meridiani Planum, where mineral deposits (hematite) suggest
Mars had a wet past.
The big science
question for the Mars Exploration Rovers is how past water
activity on Mars has influenced the red planet's environment
over time. While there is no liquid water on the surface of
Mars today, the record of past water activity on Mars can be
found in the rocks, minerals, and geologic landforms,
particularly in those that can only form in the presence of
water. That's why the rovers are specially equipped with
tools to study a diverse collection of rocks and soils that
may hold clues to past water activity on Mars.

Rather then my explain this
site I'll let the author's words entice you to visit the
treasures
here. "I
have organized things a bit differently and blended some
topics together which you won't normally find in a space- or
biology-related website. This comes from my view that
understanding what may lay out there starts with
understanding the intricacies of life here on
earth. ....I have
been captivated by space exploration since I was in grammar
school which included a mysterious recuring illness that
seemed to coincide with space missions. Like everyone, my
world view is a product of many early influences. Two of
them, at the age of 12, are most notable: reading (as best I
could) I.S.Shklovskii
and Carl
Sagan's
"Intelligent Life in the Universe" and seeing/reading
Stanley Kubric and Arthur
C. Clarke's "
2001: A Space Odyssey ". Over the ensuing three decades,
their books and TV shows have made a continual impression
upon me. If you think you see the influence of these guys
upon anything in this website you are not at all
mistaken."
How does life
begin and evolve? Is there life elsewhere in the Universe?
What is the future of life on Earth and beyond?
NAI carries out
collaborative research and education in astrobiology, the
interdisciplinary science that seeks answers to these
fundamental questions. It supports investigation of these
issues on Earth and serves as a portal to space for the
scientific community. NASA's

a Mars mission can be affordably accomplished and why it's
so important to explore the "red planet" in the first place.
And, watch Alan try out some of the tools currently being

Tight-Lipped More convincing were
closer observations with two instruments on the rover arm,
the Moessbauer and alpha particle X-ray spectrometers, as
well as the mast-mounted miniature thermal emission
spectrometer. Those devices found a pattern of salt
deposition found in the slow evaporation of water.
"This is a window into
the past on Mars unlike anything that is happening today,"
Squyres said. Water is essential to
life as we know it. Clark said the discovery, especially the
sulfate deposits, could make the past existence of life on
Mars very possible. "There

he said. Evidence

"The
NAI arrives at an exciting time for the study of life in
the universe. Advances in scientific knowledge and
technical capability over the past decade have yielded
dramatic new knowledge about the origin, distribution,
and destiny of life. We have analyzed complex organic
chemistry in interstellar clouds of gas and dust and have
discovered almost 70 planets outside of our solar system.
Life on Earth has been found thriving at environmental
extremes such as in Antarctic rocks, boiling hot springs,
and aquifers buried kilometers below the land surface. We
have found that liquid water, the one essential
ingredient for life as we know it, once flowed on the
surface of the planet Mars and probably exists today
below the icy crust of Jupiter's moon, Europa. Life on
Earth has been traced back 3.8 billion years to the
period of heavy cometary bombardment, an era that
simultaneously brought life-giving water and organic
compounds to the terrestrial planets while battering them
with lethal quantities of impact energy. We are
discovering both the fragility and robustness of life, as
we investigate the history of mass extinctions on our
planet (including extinctions taking place today), the
subtle alterations in climate triggered by volcanic
eruptions and human industry, and the destruction of our
protective shield of ozone. While we celebrate the
ability of astronauts to live and work and achieve
wonderful feats of engineering in space, we ponder the
implications of baffling physiological and chemical
changes induced by the space environment. We are only
beginning to probe the adaptability of life to conditions
beyond our home planet Earth. "
