SpaceX has made significant progress toward its ambitious goal of conquering Mars. This is due to the Falcon 9 rocket's success in launching NASA's DART, the world's first planetary defense mission. This achievement, according to Elon Musk, will help them break past the "Great Filter." According to Astronomy, the Great Filter states that "intelligent interstellar lifeforms must first perform some key steps, at least one of which must be very implausible." This stumbling block for Elon Musk might be the journey to Mars.
