NASA astronaut candidates Marcos Berríos, left, Deniz Burnham, Jack Hathaway, Christopher Williams, and Jessica Wittner, are seen during a meeting with NASA Administrator Bill Nelson, NASA Deputy Administrator Pam Melroy, and Bob Cabana, NASA associate administrator, Wednesday, Oct. 18, 2023, at the Mary W. Jackson NASA Headquarters building in Washington. Upon completion of two years of training they could be assigned to missions that involve performing research aboard the International Space Station, launching from American soil on spacecraft built by commercial companies, as well as deep space missions to destinations including the Moon on NASA’s Orion spacecraft and Space Launch System rocket.

Astronauts and astronaut candidates from NASA and the Canadian Space Agency pose for a photograph in front of NASA’s Artemis I Space Launch System and Orion spacecraft atop the mobile launcher on the pad at Launch Complex 39B on Aug. 28, 2022. The astronauts are, from left to right: Randy Bresnik, NASA astronaut; Joshua Kutryk, Canadian Space Agency astronaut; Zena Cardman, NASA astronaut; Jack Hathaway, NASA astronaut candidate; Christina Birch, NASA astronaut candidate; Reid Wiseman, NASA astronaut; Jessica Wittner, NASA astronaut candidate; Joe Acaba, NASA astronaut; Andre Douglas, NASA astronaut candidate; Kate Rubins, NASA astronaut; Jeremy Hansen, Canadian Space Agency astronaut; Stephanie Wilson, NASA astronaut; Jessica Meir, NASA astronaut; Don Pettit, NASA astronaut; Chris Williams, NASA astronaut candidate; Victor Glover, NASA astronaut; Shannon Walker, NASA astronaut; Stan Love, NASA astronaut. Artemis I is scheduled to launch Aug. 29, at 8:33 a.m. EDT. The first in a series of increasingly complex missions, Artemis I will provide a foundation for human deep space exploration and demonstrate our commitment and capability to extend human presence to the Moon and beyond. The primary goal of Artemis I is to thoroughly test the integrated systems before crewed missions by operating the spacecraft in a deep space environment, testing Orion’s heat shield, and recovering the crew module after reentry, descent, and splashdown.
