Mars doesn't HAVE winter.
About 250 days, but I haven't checked the exact number. (I guess you mean the Mars Exploration Rover mission.)
Mars' year is 687 Earth days long because it takes that amount of time for the planet to complete one orbit around the Sun. Mars is farther from the Sun than Earth, so it travels a greater distance in its orbit, resulting in a longer year.
A month on Mars, known as a "Martian month," is approximately 687 Earth days long. This is because Mars takes longer to orbit the sun compared to Earth.
it would take at least 197.456 hours to get to mars from earth
Mars rotates every 24.62296 Earth hours. Therefor making it almost as long as an Earth day by the fraction 148,000,000
30 billion years
