Aleksandra Stankovic is an aerospace psychologist and spaceflight biomedical researcher who studies how to optimize human performance and behavioral health in extreme operational environments. In this article, she describes how a person gets ready to travel to space.

The spaceflight environment presents many challenges—technical, physical, and psychological. With more people having access to space travel today than ever before, successful and safe spaceflights require varying levels of preparation before launch day.

For government astronauts, candidates undergo a rigorous two-year initial training period before qualifying for flight assignment. This training includes learning about Space Station and flight vehicle systems, studying orbital mechanics, becoming proficient in emergency procedures (like how to handle scenarios such as fire, cabin depressurization, or medical issues), conducting flight training in T-38 jets (to build quick decision-making skills in high-performance aircraft), and developing Russian language skills (since international space missions involve collaboration among astronauts from various countries).

To prepare for the microgravity environment of space, astronauts also participate in simulations of weightlessness, including parabolic flights and training in the Neutral Buoyancy Lab, a large swimming pool where astronauts practice conducting spacewalks and learn to perform tasks in their pressurized spacesuits.

Refined mapping tools that identify subsurface water ice on Mars will help determine the best targets for robotic and human missions to the planet.

NASA's Atmospheric Waves Experiment, or AWE, mission is scheduled to launch to the International Space Station in November 2023, where it will make use of a natural, ethereal glow in Earth's sky to study waves in our planet's atmosphere.

Built by Utah State University's Space Dynamics Laboratory in North Logan, Utah, AWE will be mounted on the exterior of the space station.
