How long away is mars




















On average, the distance between Earth and Mars is million miles, according to Nasa. Unmanned spacecraft travelling to Mars have taken anywhere from days to days to reach the red planet. According to physics professor Craig Patten, of the University of California, San Diego, a trip could be shortened by burning more fuel, but it would not be advisable.

Currently, the space agency is following a five-step plan for getting astronauts there, but the likely outcome will be at least a three-year journey to and back from the planet. The health of astronauts going to Mars is a major challenge for scientists and researchers for a few reasons. According to Dorit Donoviel, director at Translational Research Institute for Space Health, the first reason is because the length of the trip.

The answer to this question varies quite a bit. Both planets are in orbit around the sun and a single year for each planet one complete orbit around the sun takes a different amount of time. A year on Mars lasts for about Earth days or sols Mars days.

The distance between Mars and Earth will vary greatly depending on where each planet is in its orbit. At its closest approach to Earth in , Mars was about That's about the exact same distance it'll be from Earth when the planets have another close approach in Those happen roughly once every two years.

As Space. Though, the closest we've seen the two was When the planets are as far away from each other as possible, they could be as many as million miles apart. For reference, on average, Earth is about 93 million miles away from the sun. There are a whole lot of factors at play, like the distance and how you think you're getting there.

A rocket you made up or on the path which NASA has sent rovers? Since it would be nice to spend some time at Mars, we are only interested in the one way trip solid line which is half of the orbit, and would take half the time of the full orbit, or about nine months. So it takes nine months to get to Mars. It is possible to get to Mars in less time, but this would require you to burn your rocket engines longer, using more fuel. With current rocket technology, this isn't really feasible.

You have to plan ahead to make sure that by the time you reach the distance of Mar's orbit, that Mars is where you need it to be! Practically, this means that you can only begin your trip when Earth and Mars are properly lined up. This only happens every 26 months.

That is there is only one launch window every 26 months. After spending 9 months on the way to Mars, you will probably want to spend some time there. If you were to continue on your orbit around the Sun, then when you got back to where you started, Earth would no longer be where you left it! In order to get out of your elliptical orbit around the Sun, and into Mars orbit, you will again need to burn some fuel. If you want to explore the surface of Mars, you will also need fuel to get your lander off the surface of Mars.

On the first trip to Mars, it is necessary to bring all of this fuel with you to Mars. Maybe someday we could manufacture rocket fuel on Mars. This is also the time that Mars is smallest and faintest. The closest and furthest distances of Mars from Earth happen every 26 months. The average distance of Mars from Earth hovers around million miles million km.

Now, it is important to note that these figures are not set in stone, but are useful approximations to remember. It takes anywhere between 39 days to days for a spaceship to get to Mars. Light, on the other hand, travels to Mars in 12 minutes and 42 seconds at its average distance of million miles. So far, in this article, we have learned the distance from Earth to Mars at two important points in its orbit. We can now proceed to understand how long it takes to get to the famous red planet.

There are two ways to go about this. First, we will look at the time light takes to reach Mars. Light travels the fastest of all known objects because it has no mass. Its speed is a whopping , miles per second.
