If you wanted to make a one-way trip to Mars it would take about nine months but a round-trip all in all would take about 21 months as you would need to wait about three months for Earth and...
If you were to travel at the speed of light, which is around 300,000 kilometers per second or 186,000 miles per second in a vacuum, you would reach Mars at its closest possible approach to Earth in just 3.03 minutes, or 182 seconds.
Take getting to Mars. Probes sent to the Red Planet by NASA and other space agencies spend about seven months in space before they arrive at their destination. A trip for humans would probably be...
The way you propose would require reducing orbital velocity of the Earth from roughly 30 km/s to 0, then climbing up the Earth's and Solar system's gravity well to Mars' orbital altitude, and waiting there for Mars to hit us at its orbital speed of about 24 km/s!
Mars Orbit insertion is the point in the mission when a spacecraft arrives just short of Mars, firing onboard rockets to slow its speed relative to the planet, and it is captured into a long, looping orbit.
The two fastest travel times from Earth to Mars are for the Viking 6 and Viking 7 spacecraft, which took 155 and 128 days respectively. Both of these spacecraft were on flyby missions to image Mars, so they didn't need to slow down as they approached Mars as orbiters, landers and rovers need to do.
Your trip to Mars will take seven months (that's taking the shortest possible route cruising at about 78,000 kph). In that time you will share an 8 by 11-metre space with at least four people (if you found COVID-19 lockdowns challenging, this might not be the flight for you). Here's what your spaceship might look like:
If you could jump in a car and travel at 161 kph (100 mph), it would take about 14,583 days or 40 years to reach Mars, but if you wanted some exercise, you could walk (at 6kph or 3.7 mph) and get there in 1,065 years!
Quick Facts. Mars has two moons: Phobos and Deimos. Phobos is 13.8 miles across, and Deimos is 7.8 miles across. Periodic dust storms on Mars can last for months, making nuclear fission power a more reliable option than solar power. Temperatures on Mars can range from -284 degrees F to 86 degrees F. The atmosphere on Mars is 96% carbon dioxide.
Unmanned spacecraft travelling to Mars have taken anywhere from 128 days to 333 days to reach the red planet. According to physics professor Craig Patten, of the University of...
