Mars takes longer to orbit the sun than Earth does, so the distance between the two planets varies greatly. Spacecraft can only travel between the two planets when their orbits bring them relatively close together, which occurs roughly every 26 months. The journey from one planet to the other takes about 8 months, so the shortest time you could spend on Mars would be 18 months.
What else can I help you with?
Which position will earth be in after 18 months have passed?
It would be positioned approximately 270 degrees from its current location after 18 months. This means it would be on the opposite side of the sun in its orbit.
Why haven't we gone to Mars yet?
Some of the main reasons: - Cost - Lack of public support - Time: It would take to get to and from Mars. Six months to get there, staying there for 18 months(waiting for Mars and the Earth to line up) and six months back. - Physiological problems due to space travel like bone degeneration (from lack of gravity) and radiation exposure that we have not yet resolved. - Psychological effects of prolonged space travel like limited room/ human contact. - Limits of current technology to allow us to carry sufficient supplies (oxygen, water, food) the necessary distance - Lack of appropriate habitat to support astronauts during the time they would have to stay on the planet's surface - No real good reason to go. (Yes, it would be neat, epic even, from an historical standpoint, but Mars itself has not shown to have anything useful to people)
When are Mars and Earth the closest?
Six to seven months for current space probes (2011-2012).Because Earth and Mars have separate and unrelated orbits, the actual closest approach (about 58 million kilometers) only occurs once every few decades. But each year, the Earth comes within 60 to 100 million kilometers of Mars. With current technology (2012), space probes take around 7 months to make the journey to Mars, and usually longer. Any manned mission would probably need to reduce this time well below 6 months each way.
How much would a person weigh on mars planet compared to on earth?
About 2 times less, so if you weigh 50 pounds on Earth, you would weigh about 18(mars is a bit less massive than half the size of earth) on Mars.
When was Biker Mice from Mars created?
Biker Mice from Mars was created on 1993-09-18.
Why would you have to be on mars at least 18 months at a time?
A person would need to be on the planet Mars for at least 18 months before they could return home because of the launch window. It would take about 8 months to reach the planet and then another 18 months on the planet until the next launch window to open.

What is the revolution in mars?
18 months
How long did it take the Mars rover to get to Mars?
It would take about 7 months to get to Mars
How long would it take to get to mars and back?
A round trip to Mars can take anywhere from 18 months to 3 years, depending on the alignment of the planets and the trajectory chosen. The actual time spent on the surface of Mars would be limited to a few weeks, as the rest of the time would be spent in transit. Extensive planning is required to ensure the safety and well-being of astronauts during such a long-duration mission.
If it takes 18 months to travel from earth to mars how long would it take to travel from earth to Jupiter?
It would take about 9 years to travel from Earth to Jupiter, assuming a similar speed and trajectory as the trip from Earth to Mars. Jupiter is much farther away from Earth than Mars, so the journey would be significantly longer.
How many months in 18 years?
That would be 18 x 12 which is 216 months
What is the time to get to Ceres?

How much jail time do you serve out of 18 months?

What age would heifers calve for the first time?
That really depends on when she was bred. The average gestation period of a cow (or heifer) is around 285 days. Thus, if a heifer was bred when she was 15 months old, then she would likely give birth by the time she is 24 months of age. If she was bred when she was 18 or 20 months old, then she would calve out when she's 27 to 29 months of age.
