The main components of the spacecraft are:

1. Payload: This is the scientific or operational instrumentation that the spacecraft is designed to carry out its mission. This could include cameras, sensors, communication systems, and other instruments.

2. Structure: This is the physical frame of the spacecraft, which provides structural support and protection for all other components. It also helps to maintain the spacecraft's orientation in space and control its attitude.

3. Propulsion System: This is used to provide thrust to move the spacecraft through space and to make changes in its orbit or attitude. It can include chemical thrusters, electric propulsion systems, or other types of propulsion systems.

4. Power System: This is used to provide power for all of the spacecraft's systems and instruments. It can include solar panels, batteries, fuel cells, or other types of power sources.

5. Thermal Control System: This is used to regulate the temperature inside the spacecraft and protect sensitive equipment from extreme temperatures in space. It includes insulation materials and radiators that release heat into space when necessary.

6. Communication System: This is used to send data from the spacecraft back to Earth or other locations in space as well as receive commands from ground control stations on Earth or elsewhere in space. It includes antennas, transceivers, receivers, transmitters, amplifiers, etc..

Your figures should contain a caption which describes the figure to
the reader. Figure captions go below the figure. Your figures should
{\bfseries also} include a description suitable for screen readers, to
assist the visually-challenged to better understand your work.

Figure captions are placed {\itshape below} the figure.

\subsection{The ``Teaser Figure''}

A ``teaser figure'' is an image, or set of images in one figure, that
are placed after all author and affiliation information, and before
the body of the article, spanning the page. If you wish to have such a
figure in your article, place the command immediately before the\\ \verb|\maketitle| command:\\ \verb|\begin{teaserfigure}|\\ \verb| ...|\\ \verb|\end{teaserfigure}|\\

Galileo was an unmanned spacecraft launched by the European Space Agency (ESA) in 1989. It was the first spacecraft to orbit Jupiter, and it provided scientists with a wealth of data about the planet and its moons. Galileo's mission lasted from 1989 to 2003, when it was deliberately crashed into Jupiter's atmosphere. During its mission, Galileo made numerous discoveries, including evidence that Jupiter's moon Europa may have a subsurface ocean of liquid water.
