How long would it take to reach Mars with a constant acceleration of 1G?
Suppose you could travel to Mars accelerating at 1 g for the first half the trip, then decelerating at 1 g for the final half of the trip. Along the way you’d feel a force equal to the force of gravity you’re used to, and you’d get there quickly. How quickly? According to the show, just three days.
Is constant 1G acceleration possible?
At a constant acceleration of 1 g, a rocket could travel the diameter of our galaxy in about 12 years ship time, and about 113,000 years planetary time. If the last half of the trip involves deceleration at 1 g, the trip would take about 24 years.
How long would you have to accelerate at 1G to light speed?
It would take 353,7 days of constant 1G (9,81 m/s^2) acceleration to reach the speed of light. In that time you would travel 4,58 billion Km. You can’t reach the speed of light.
What acceleration is 1g?
But wait! It gets even worse. If you measure the acceleration based on the changing speed, it gets high—very high. At the end of the clip, the spacecraft is traveling around 25 million meters per second and has an acceleration of about 46,119 m/s2.
Can you accelerate in space?
The astronauts on board the International Space Station are accelerating towards the center of the Earth at 8.7 m/s², but the space station itself also accelerates at that same value of 8.7 m/s², and so there’s no relative acceleration and no force that you experience. This same principle works on extreme scales, too.
Can you accelerate indefinitely?
As long as you have useable energy in your ship, you can use it to accelerate indefinitely your propellant in the opposite direction you want to accelerate; this is how rockets work.
Is acceleration constant in space?
The astronauts on board the International Space Station are accelerating towards the center of the Earth at 8.7 m/s², but the space station itself also accelerates at that same value of 8.7 m/s², and so there’s no relative acceleration and no force that you experience.
