Hi All,

This is time it takes to travel a distance i Space, Not Space Time Travel as with Doctor Who.

More math stuff here. Ya know for someone that hated math in school I play with it a lot now, UG!

Anyway the question is. When in space, and away from the gravitational
effects of the Earth. What rate of acceleration is needed to end up
feeling as if there is 1 G of force on the Astronaut?

Would that freefall proverbial 32 feet per second per second be the number here also?

In other words what rate of acceleration, is needed to feel a constant never ending force of 1 G?

Now this is the even more interesting part.

I know we do not have right now any propulsion systems that are capable
of doing this. But if we were to it would cure soo many problems. With
space travels.

Say we did have a propulsion system that is capable of making this 1 G
of force for as long as we want it to. Several things come to mind.

Mainly the removal of the problems physically that happen to the
astronauts in long duration flights loss of muscle and bone mass for the
first couple.

The next is the time of the trip. This system would have to shorten the trip GREATLY I would think.

Anyone care to try to make a calculation on this?

Say both to the moon as well as to mars.

Now current technology take 3 days to go to the moon and 8 months to go
to mars. But 99% of the trip is under 0 or near 0 gravity or G forces.

Now the question is, again if we were able to make a propulsion system of doing this, what would happen,?

We launch Yeah LOTS of G forces at first but once left the Earths
Gravitational forces and onto either the moon or mars, we now are
accelerating at 1 G force.

I would assume at close to the 1/2 way point we would turn the ship
around and again keep running the engines, but again with 1 G forces
worth of thrust so to start to slow the ship down now.

The questions are

On both trips to the moon as well as to mars, I would assume max speed
would be at that 1/2 way point,, how fast would they be traveling?

And then the big one how long would the trip now take?

Joe
