Launching of the beetles to Earth

Realizing he cannot return to Earth himself, Grace decides to launch the four beetle probes, each carrying a mini-farm of Taumoeba-80 and a USB drive with all his scientific findings. He programs them to return to Earth, hoping they will provide humanity with the solution to the Astrophage problem. This act is a desperate gamble, as it means Grace will likely never see Earth again, but it represents his commitment to saving his species even at the cost of his own survival.
