Using Reaction Control Thrusters or Cold Gas Jets (small thrusters). The astronauts fire them in the opposite direction that the spacecraft is traveling and this thrust slows down the craft.
The astronaut floated weightlessly in the spacecraft, looking down at the Earth below.

Astronaut
Cosmonaut or astronaut.
An astronaut landing on Mars would require a spacecraft to enter the Martian atmosphere, slow down through a combination of aerodynamic drag and parachutes, and use retro-rockets for a controlled descent to the surface. The spacecraft would need to deploy landing gear to touch down safely on the Martian terrain.
The plural form of astronaut is astronauts.
An astronaut commands, pilots, or serves as a crew member of a spacecraft.
The astronaut is connected to the spacecraft by a tether or umbilical cord. This ensures they remain secured to the spacecraft while performing spacewalks or other external activities. The tether also provides communication, power, and life support systems to the astronaut.
An astronaut or cosmonaut.
A person who is trained to travel in a spacecraft.
In space, there is no air resistance to slow down spacecraft traveling at constant velocity. Additionally, spacecraft can use thrusters or gravitational assists to adjust their speed if needed. The laws of physics allow spacecraft to maintain their speed in the vacuum of space.
A parachute would not work in the vacuum of space as there is no air for it to catch and create drag. Instead, spacecraft approaching the moon slow down through a combination of a retrograde rocket burn and gravity assist maneuvers to enter lunar orbit. Mission planners carefully calculate the spacecraft's trajectory and use precise engine firings to control its speed and trajectory.
