The planets Earth and Mars orbit the sun at different speeds.
REPUBLIKA.CO.ID, JAKARTA — Although the plan is to send astronaut the Mars keep echoing, the fact is not easy to wade through the journey. Mars and Land it is more than 99 million kilometers and is almost 250 times farther from our planet than the Moon.
Additionally, missions to Mars will last 21 months or more. That duration is a lot of time for humans to spend in space. But more importantly, a mission to Mars could also be fatal for the astronauts who are part of the mission. Indeed, not only fatal, but can even be lethal to the astronaut himself.
Moreover Planet Earth and Mars orbit the Sun at different speeds, and the distance between the two planets keeps changing throughout the year. Therefore, missions to Mars must occur during the launch window where the two planets are closest. This happens every 26 months. This means that astronauts arriving on Mars may have to wait a while before they can return to Earth.
Reported by indian express, Also, on Thursday (5/1/2023), there’s a small chance that a solar flare erupting toward the Sun could expose astronauts to much higher levels of radiation than they can spare, even if the spacecraft is designed to accommodate normal amounts of radiation.
In addition to protection, the spacecraft must also carry a much greater supply of life support systems, including oxygen and water for the duration of the mission. If any of these critical systems fail or fail during the long journey to and from Mars, the astronauts will be dry thousands of kilometers away from Earth.
