That was a long, dry, airless age ago. The "cel gel" inside me takes the longest to clear. The training helps, but I'm still not used to it. I don't think anyone is. The immersion isn't long but the accelerations forces have gone way up as journey times are cut. My organs all feel fine, the pressure was spot on, with a days rest, even my liver didn't hurt this time and getting the suit on is painfree. Its annoying having to keep the ventilator on outside on this planet, but it has its advantages. The animals have no chance of personalizing us. We smell and look the same, its perfect.
Today we make history here, but nothing here will ever know it. All my training, my life has been focused towards this point. Countless trials and successes with animal breeding and now this. The evolution has been manageable for ages. We know the animal blends are past the convergent threshold for the scale and profile to support the survival of the first of the new species. I'm not volunteering for the monitoring crews and they won't need me, so I won't be back. I'm overthinking this, just do it. Clear my mind and press the button. Except now it is our genes and these animals, specially chosen as they are to closest genetically to our race. As I release it the system syncs with all the others, there's a small delay and then its done. The teams are excited, lots of chatter on air. I'm getting on the ship as soon as I can. I know there is nothing I can do in the rest of my life (well the 78.3+ years I have left) that can get close to what I helped do here to make the first humans.
