Mars, along with our solar system, was formed from a large spinning disk of gas and dust. Astronomers believe that this occurred about 4.6 billion years ago. Reaching Mars will be the longest journey in human history. The trip has a distance of about 225 million kilometers, with six months to arrive, and six months to return to Earth.
There is a lot to take under consideration for a potential mission to the Red Planet. One of these things will be figuring out how to get there and having the necessary materials. A problem that astronauts will encounter is space radiation. Since astronauts will be away from the protection of the Earth's magnetic field, charged particles from high energy cosmic rays can negatively impact their health. The chances of getting cancer and serious health issues increase with exposure to these rays.
Mars has an atmosphere that is 100 times less dense than Earth. While our atmosphere is nitrogen and oxygen rich, the Martian atmosphere is composed primarily of carbon dioxide. With an atmosphere like that, Mars would take a person's breath away.
Astronauts will need to pack plenty of supplies like food and tools, and grow their food. Engineers are creating a 3D-printer to build tools to use for planting, eating, and returning back to Earth.
There is plenty of excitement and work being done to get humans to step foot on Mars and reach this milestone in space exploration. But humans must also be responsible and careful to not damage the planet, since we do not know how badly we can impact it.
