Spacecraft Elegy
Apr 24, 2017

Spacecraft Elegy Spacecraft give their all in the name of exploration

Exploration: It’s exciting, it’s novel, and you can’t always count on a round-trip ticket.  You can boldly go, but you might not come back.  That’s no showstopper for robotic explorers, though.  Spacecraft go everywhere.

While humans have traveled no farther than the moon, our mechanical proxies are climbing a mountain on Mars, visiting an ice ball far beyond Pluto, plunging through the rings of Saturn, and landing on a comet.  Oh, and did we mention they’re also bringing rock and roll to the denizens of deep space, in case they wish to listen.

We consider some of the most daring explorers since the 16th century – made of metal and plastic - venturing to places where no one else could go.  What have they done, what are they doing, and at what point do they declare “mission accomplished” and head for that great spacecraft graveyard in the sky?

ENCORE  Ask anyone what extraordinary powers they’d love to have, and you’re sure to hear “be able to fly.”  We’ve kind of scratched that itch with airplanes.  But have we gone as far as we can go, or are better flying machines in our future?  And whatever happened to our collective dream of flying cars?   We look at the evolution - and the futu

We all may retreat to our protective shells, but evolution has perfected the calcite variety to give some critters permanent defense against predators.  So why did squids and octopuses lose their shells?  Find out what these cephalopods gained by giving up the shell game.
