This recruitment drive aims to identify individuals who will support the Artemis program and future human missions to Mars. Interested U.S. citizens must submit their complete documentation by 11:59 p.m. EST on Thursday, December 3, 2025. ## Strategic Exploration Goals The selected candidates will play a critical role in establishing a long-term human presence on the lunar surface. These explorers will train to operate near the lunar South Pole and develop systems necessary for deep space travel. Their work will directly contribute to the first human missions to the planet Mars. ## Rigorous Selection Timeline NASA plans to finalize its selection process by late 2027 to begin the training phase for the new cohort. This follows the 2024 call for applications, which resulted in the selection of 10 candidates from over 8,000 applicants. These individuals are currently finishing a two-year training program at the Johnson Space Center. ## Educational Qualification Requirements Applicants must hold a master's degree in a STEM field, including engineering, biological science, physical science, or computer science. Alternatively, candidates may qualify by completing two years of doctoral study in a relevant technical field or by earning a medical degree. Specialized training in a recognized test pilot school is also accepted. ## Professional Experience Standards Beyond academic credentials, candidates must possess at least three years of related professional experience. Pilots are required to have 750 hours of command time in high-performance jet aircraft or 1,500 hours of total flight time. Medical professionals may count their residency period toward the three-year requirement if completed before July 2027. ## Training and Physical Standards Selected candidates must pass the NASA long-duration spaceflight physical examination to ensure they can handle the rigors of space. Training encompasses diverse skills including spacewalking, lunar geology, and operating high-performance aircraft. Leadership, teamwork, and communication skills are considered essential attributes for all successful applicants joining the current corps of 32. ## Historical Context of Selection Since the 1960s, NASA has selected 370 individuals to train as astronaut candidates for increasingly complex missions. The agency continues to rely on exceptional Americans who demonstrate technical excellence and courage. This legacy of exploration remains central to the agency's mission of expanding human knowledge beyond the Earth and the Moon. ## Future of Human Spaceflight As the agency enters a new golden age of innovation, the role of the astronaut is evolving to meet unprecedented challenges. The upcoming class will not only contribute to scientific advancement but also inspire future generations of engineers and scientists. Their contributions will define humanity's footprint in the solar system for decades. ## Sources covering this story - https://www.nasa.gov/news-release/la-nasa-busca-a-la-proxima-generacion-de-astronautas/ — --- _Summary written by Brifing from the original reporting.
