August and September 2011 mark 34 years in
the journeys of
Voyager 1 and 2. The two scientific probes, progeny of the
Mariner program, were sent out to survey this solar system and beyond.
Voyager 2 completed the
Grand Tour in 2009 (excluding Pluto), and
Voyager 1 is getting closer to interstellar space (
previously). Both scientific probes were sent out in with
a time capsule from 1977,
golden records secured in plain view on the outside of the Voyager Spacecraft. These
greetings from earth (alt links: Coral Cache, Archive.org) were recorded in the form of 116 images,
a collection of sounds of this planet,
greetings in
55 languages (
YT),
27 songs from around the world, and
brain waves of Ann Druyan, then recently
engaged to Carl Sagan. For all that work, the
"Mix Tape of the Gods" almost didn't get sent into space because of some last-minute writing in the run-outs.

On October 9th, NASA spacecraft will run into the moon, and on purpose. The
Lunar Crater Observation and Sensing Satellite (
LCROSS) and its rocket's
Centaur upper stage will impact the moon, with the goal of sending some of the (possibly present) ice above the lunar surface. Once out of the eternal shade of the moon's south pole, sunlight will break the ice up into H+ and OH- molecules, which can be detected by the
Lunar Reconnaissance Orbiter (
LRO). The
initial impact site was the crater Cabeus A, but the target was
later changed to Cabeus (proper), selected for highest hydrogen concentrations with the greatest level of certainty, and for the high-contrast back drop to detect ejecta and vapor measurements. NASA has provided
guides for amateur observations of the impact,
a facebook group, and
a Twitter feed so you don't miss the moment.
