And now the news from Alpha Centauri(Oh, I’ve waited for so long to utter those words! News. From Alpha Centauri. Wow!)

The Exoplanet next door: Astronomers have discovered the lowest-mass planet yet orbiting a Sun-like star. But the even-more exciting news is that it orbits α Centauri B, a member of the stellar system that is our Solar System’s nearest neighbour. Although nearly identical to Earth in mass, the planet is much closer to its star than Mercury is to the Sun, meaning that it is likely a scorched and barren rock.

Citizen engagement is essential to our fast-changing civilization. Politics could certainly use more empowerment of common citizens. So could innovative commerce, and even national defense relies on a robust citizenry. But one area with especially bright prospects, is crowd-sourced -- or individual participation in -- inventiveness and science.

A balanced and well-researched Wired article by Jason Kehe reveals the latest "yoo-hoo transmission to aliens"  stunt.  Of course I consider these things to be, at best, dopey, with a small but significant chance of being thoughtlessly dangerous for all of humanity.  Above all, to cast such noises outward, based on untested assumptions, without at least offering to discuss it first with our planet's population and its greatest sages?  That is simply rude.

INTRO:  On September 14, 2012, I served as the guest speaker at the grand opening and dedication of the new Structural/ Materials Engineering Building at UC San Diego (UCSD).  Present also and offering remarks were Frieder Seible, Dean of the Jacobs School of Engineering; Pradeep Khosla, the new Chancellor of UCSD; Nathan Fletcher, State Assemblyman; Seth Lerer, dean of UCSD's Division of Arts and Humanities; and Karl Beucke, President of Weimar's famed Bauhaus Universit

I've been feeling a bit inspired about our prospects in space, lately.  Foremost (of course) by the incredible competence displayed by the makers of the Curiosity probe that landed on Mars, last week, and the JPL controllers and the citizenry that backed such a wonderful venture.
