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.
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)
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.
Biker Mice from Mars was created on 1993-09-18.
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.
A full year on Mars is about 687 earth days. That is about two earth years. This means that when you are 18 years old on the earth, you would be 9 years old on Mars. However, this doesn't mean that you'd look twice as young as you really are, you'd just have a different age but look exactly the same as you would on the Earth at your age.
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.

18 months
24 months
That would be 18 x 12 which is 216 months

If you are "well-behaved" in prison, then most people are eligible for parole in 75% of the jail time, so it would be 13 and a half months.

It can be anywhere from 2-18 months. If nothing has happened in 18 months see a doctor.
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.
Well, you would be 18 weeks pregnant. 14 weeks is the begining of your 2nd trimester so you would be 4 weeks into your second trimester. Or you would be 4 1/2 months along.
18 months into two years would be expressed a 3/4 of two years.
