Step By Step-Some Humble Space Links

Frank Drake brings some realism to the S.E.T.I. debate.  The space-time distances are a huge hurdle, and the challenges of becoming a spacefaring civilization make the journey to nearby star systems fairly impractical at the moment.

The less evidence and fewer data points there are, the more rampant the speculation, inventive the Sci-Fi imaginings, and important the foundation to create such new fields of knowledge.

In addition to recent rapid advances in ‘seeing’ with radio waves, gravity waves and light, and we’ve got better tools to get a little further out into our own neighborhood.

This means we could find out if we can find some life on Mars (methane spikes), Jupiter’s icy moon Europa and Saturn’s icy moon Enceladus:
