i have very supid question. time of which planet will be used to measure those 8 years (of marko earth mission)?
I just decided to calculate how long these 8 years will last on different planets. i got big difference in days (more when 600). it means that 8 years on adastra, its only 6,5 years on earth.
in this case, amicus will be arrive at earth 1,5 years earlier, or he will wait 2 more years of adastra.
sorry for my eng...
