Why
name a crater after Pablo Neruda?
Our
planet is not a single entity separate from the rest
of the universe. It is a living celestial body that
is dependent on every other living thing. Earth was
bombarded with meteorites and other particles, but through
the shifting of continents and changing landscape of
our planet, the damage is not apparent. While other
planets have their scars exposed as craters. Craters
on other planets and on our own Moon are clear examples
of our connectivity and dependency with everything in
the universe and of our own frailty. Much of Pablo Neruda's
work deals with humanity's frailty and passion for life.
He is one of our greatest poets and the people's poet.To
honor him and his work, we have petitioned the International
Astronomical Union to name a crater on Mercury after
him. Why Mercury? There are strict naming conventions
developed by the Union, and only craters on Mercury
can be named after literary figures. For exampe, a crater
located at 41.4N (Lat) and 110.4 (Long) on Mercury is
named after Walt Whitman. We
will announce the results of our petition when we learn
more from the International Astronomical Union.

Mercury,
the least explored terrestrial planet, is fundamental
to understanding the evolution of the inner solar system.
Visited by only one spacecraft, Mariner 10, it
is a planet of superlatives, an "end-member" among the
rocky planets. Its density (corrected for self-compression
by gravity) is the highest of any planet. Its ancient
surface records processes from the earliest part of
planetary formation. Its exotic atmosphere is the thinnest
among those of all the terrestrial planets. It is the
only terrestrial planet besides Earth to possess a global
magnetic field. And temperatures on this planet of fire
and ice vary from nearly the highest in the solar system,
at the equator, to among the coldest, in the permanently
shadowed poles where paradoxically ice deposits seem
to lurk.
MESSENGER
will peel back Mercury's veil of mystery. MESSENGER
is a MErcury Surface, Space ENvironment,
GEochemistry, and Ranging mission to orbit
Mercury following two reconnaissance flybys. MESSENGER
will investigate key science questions using an optimized
set of miniaturized instruments: What is the origin
of Mercury's high density? What are the composition
and structure of its crust? What is Mercury's tectonic
history, and is its surface shaped by volcanism? What
are the characteristics of the thin atmosphere and miniature
magnetosphere? And what is the nature of the mysterious
polar caps? The scheduled launch is March 2004.
