Nakolik jsou ale re\u00e1ln\u00e1?\u00a0Zde je pot\u0159eba rozli\u0161ovat, na jakou planetu se chceme vypravit. Bude to n\u011bjak\u00e1 v\u00a0na\u0161\u00ed slune\u010dn\u00ed soustav\u011b, nebo chceme prozkoumat n\u011bkterou, kter\u00e1 ob\u00edh\u00e1 \u00fapln\u011b jinou hv\u011bzdu?

Cestu k\u00a0na\u0161im soused\u016fm, tedy k\u00a0Marsu a Venu\u0161i, bychom s\u00a0dostatkem financov\u00e1n\u00ed zvl\u00e1dnout mohli. Jen je pot\u0159eba si uv\u011bdomit, \u017ee tyto sebou p\u0159in\u00e1\u0161\u00ed ur\u010dit\u00e9 probl\u00e9my, na kter\u00e9 je nutn\u00e9 b\u00fdt p\u0159ipraven.\u00a0V\u00a0prvn\u00ed \u0159ad\u011b je jasn\u00e9, \u017ee oba tyto sv\u011bty nejsou zrovna p\u0159\u00edjemn\u00e9. Na Venu\u0161i ani p\u0159ist\u00e1t nejde, nebo\u0165 jej\u00ed atmosf\u00e9ra je p\u0159\u00edli\u0161 hust\u00e1 a tlak by lo\u010f rozma\u010dkal i s\u00a0pos\u00e1dkou uvnit\u0159, je\u0161t\u011b ne\u017e by stihla dosednout. Na Marsu sice takov\u00fd probl\u00e9m nen\u00ed, je v\u0161ak stejn\u011b nehostinn\u00fd a pust\u00fd.\u00a0\u00a0Po\u010d\u00edtat je pot\u0159eba tak\u00e9 s\u00a0t\u00edm, \u017ee cesta bude trvat p\u0159ibli\u017en\u011b dva roky. Pokud se bude jednat o cestu s\u00a0n\u00e1vratem, je nutn\u00e9 tuto dobu zv\u00fd\u0161it na \u010dty\u0159i a\u017e p\u011bt let. To je velmi dlouh\u00e1 doba, kterou lid\u00e9 str\u00e1v\u00ed uzav\u0159eni spolu na velmi mal\u00e9m prostoru. Ponorkov\u00e1 nemoc existuje, a psychologick\u00e9 probl\u00e9my, kter\u00e9 by se vyno\u0159ily, nelze br\u00e1t na lehkou v\u00e1hu.\u00a0Je tu samoz\u0159ejm\u011b tak\u00e9 ot\u00e1zka pot\u0159ebn\u00fdch z\u00e1sob, a\u0165 u\u017e se jedn\u00e1 o j\u00eddlo a vodu, oble\u010den\u00ed, nebo i n\u00e1hradn\u00ed d\u00edly pro p\u0159\u00edpad, \u017ee by se na lodi n\u011bco porouchalo.
