While on one hand NASA is preparing to launch the Artemis I spacecraft to pave the way for a crewed flight test and future human lunar exploration, on the other, a massive 150-foot wide asteroid just passed the Earth from very close quarters. NASA revealed that an asteroid named 2022 QO31 made its closest approach of around 3.32 million miles to Earth today.
