According to NASA, the trip to Mars takes about seven months and about 300 million miles. Astronauts could fly over Mars by 2033

If you want to send a spacecraft all the way to Mars, first you’ll need a fast rocket to escape the pull of Earth’s gravity. The heavier your spacecraft, the more powerful your rocket needs to be to lift off. Next, make sure you launch at the right time. Mars and Earth orbit the sun at different speeds and distances

The United States has sent astronauts to the moon and into orbit around Earth. Many space enthusiasts dream of the day when there will be a manned mission to the “Red Planet” of Mars

Like Earth, Mars revolves around the Sun, although on a different path than Earth does. Every 26 months, Mars reaches a point at which it’s as close as it ever gets to Earth. This point is called oppositionand, at opposition, Mars is between 34.6 and 63 million miles away, depending on what year it is.

The lowest energy transfer to Mars is a Hohmann transfer orbit, which would involve a roughly 9-month travel time from Earth to Mars, about 500 days (16 mo) at Mars to wait for the transfer window to Earth, and a travel time of about 9 months to return to Earth. This would be a 34-month trip

The total journey time from Earth to Mars takes between 150-300 days depending on the speed of the launch, the alignment of Earth and Mars, and the length of the journey the spacecraft takes to reach its target. It really just depends on how much fuel you’re willing to burn to get there.

The spacecraft departs Earth at a speed of about 24,600 mph (about 39,600 kph). The trip to Mars will take about seven months and about 300 million miles (480 million kilometers

Why would it take 7 months to reach mars

As a result, a spacecraft launched when mars are at a distance of 55 million kilometers from earth would have to travel 470 million kilometers to get to the red planet. This, in turn, would last about 7 months. That’s why it takes such a long time to get from earth to mars.

The Trip to Mars

Engineers on Earth keep close tabs on the mission during cruise. Major activities include:

• Checking spacecraft health and maintenance
• Monitoring and calibrating the spacecraft and its onboard subsystems and instruments
• Performing attitude correction turns (slight spins to keep the antenna pointed toward Earth for communications, and to keep the solar panels pointed toward the Sun for power)
• Conducting navigation activities, such as trajectory correction maneuvers, to determine and correct the flight path and train navigators before atmospheric entry. The last three correction maneuvers are scheduled during approach.
• Preparing for entry, descent, and landing (EDL) and surface operations, a process which includes tests of communications, including the communications to be used during EDL.
