I eventually got round to watching The Search for a New Earth…

Hearteningly I had anticipated most of the issues and challenges outlined in the programme in my similarly-themed tetralogy Lights in the Sky…

What I hadn’t anticipated were: plasma rockets as a means of space propulsion rather more efficient than chemical rockets (I may substitute these in the relevant chapter, as it would only be a modest change), Proxima b as the Earth-like planetary destination, and artificially-induced hibernation as a means of dealing with the length of time needed to traverse the distance between here and the Centauran system…

But overall, not bad!  

I enjoyed the programme (…at least at first!), but after a while it began to strain credulity, featuring as it did; postage stamp-sized space probes capable of reaching another star system (and beaming back data!), hibernating bears immune to radiation sickness, and hibernation-inducing serum obtained from hamsters, for Christ’s sake!  And I began to wonder if the whole thing wasn’t some kind of late April Fool’s joke! Then I remembered the original Tomorrow’s World (my favourite television programme growing up!), anchored as it was by overly-enthusiastic, manically-grinning presenters, and showcasing (on a weekly basis) ground-breaking technological developments that were never heard of again!  

But seriously folks, there were a couple of important issues that weren’t raised by the programme. Firstly, any manned mission to Proxima b would appear to be asking the putative crew members to spend twenty years of their lives in hibernation, time they would presumably never get back! The question of whether being in hibernation would slow the ageing process was never discussed, but it doesn’t seem to do so in the case of bears (or indeed, hamsters!).

Secondly, we have the elephant in the room!  The Proxima expedition (like my Alpha Mission!), would do nothing for the billions left back on Earth, presumably to die miserably in the impending ecological catastrophe! Eventually, a significant number of those billions would realise this and start to seriously oppose these plans, asking (quite reasonably) why the effort and the (billions of) dollars going into an expedition to the stars aren’t being spent sorting out the problems here on Earth!   

I was also re-assured by the rather precarious prospect offered to any settlement on the planet orbiting Proxima Centauri, with its one face permanently turned towards its primary (and being baked by its rays), while the other remains in deep freeze, and with only a thin strip of supposedly habitable planet between the two! I decided that, on reflection, I much preferred my world, Alpha 5, as the fictional destination for my explorers cum colonists…   

Imaginary worlds need to be better than the one we live in, or why else would we invent them?
