The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). During that journey, engineers have several opportunities to adjust the spacecraft's flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars
About 250 days, but I haven't checked the exact number. (I guess you mean the Mars Exploration Rover mission.)
488.00 days
The "day" on Mars, the time it takes for one complete rotation, is about 24.62 Earth hours.
it takes 88 days for mars to complete its revolution round the sun
A day on Mars, known as a "sol," is approximately 24 hours and 39 minutes long. This is the time it takes for Mars to complete one full rotation on its axis.
It took many many years
I believe they have.
Apollo 11 did not go to Mars; it was the mission that carried the first humans to land on the Moon in 1969. It took Apollo 11 approximately 3 days to travel from Earth to the Moon. Mars is a different planet, and no human mission has yet traveled there.
It takes 687 days for the planet mars to orbit the sun.
To take a series of photos of Mars and study the atmosphere.
It would take a radar signal 3049600 seconds to complete a round-trip between Earth and Mars. Divide by 60 to get minutes and divide again to get hours.
Using current technology: it can take as little as 6 months and as long as a year to get to mars at optimum position
