The number of new U.S. astronauts officially added to NASA ranks last Friday. “The new graduates may be assigned to missions destined for the International Space Station, the Moon, and ultimately, Mars. With a goal of sustainable lunar exploration later this decade, NASA will send the first woman and next man to the surface on the Moon by 2024. Additional lunar missions are planned once a year thereafter and human exploration of Mars is targeted for the mid-2030s.” (NASA - January 10, 2020)
