Scroll to fly — five steps, seven months, one red planet.
Step 1 · Launch
Wait for the window
Earth and Mars line up for an efficient trip only about every 26 months. Miss it, and you wait two more years.
Step 2 · Leave Earth
Escape at 25,000 mph
To break free of Earth’s gravity, a spacecraft needs to reach roughly 25,000 miles per hour.
Step 3 · Cruise
Seven months of nothing
The trip takes about seven months. Engineers steer with small engine burns along the way.
Step 4 · Arrive
Seven minutes of terror
Landing takes about seven minutes from the top of the atmosphere to the ground — too fast for anyone on Earth to help, because signals take several minutes each way.
Step 5 · Explore
A day lasts 24 hours 37 minutes
On Mars you would weigh about 38% of your Earth weight. Sunsets there glow blue.
