NASA has 10 new astronauts chosen from more than 8,000 applicants. The space agency introduced its 2025 astronaut class Monday. The six women and four men will undergo two years of training before becoming eligible for spaceflight, including trips to the moon and possibly Mars. It’s the 24th astronaut class for NASA since the original Mercury Seven made their debut in 1959. The previous class was in 2021. Only 370 people have been selected by NASA as astronauts, making it an extraordinarily small and elite group.
