An equally significant event is the dispatch of an expedition to Jupiter's moon Europa. As we all know, Europe is covered with ice, and there could theoretically be liquid water under its layers, which is heated from the bottom of a huge ocean. So it will also be a landmark event if something is revealed there.
Most likely, these can be the simplest microorganisms, but I think everyone will hope for more.
I hope that the expedition will not be rescheduled to 2025 as expected (if problems arise) and we can all witness the existence of extraterrestrial life.
