Dear Ugordan, can you explain to me again? I'm unclear that how we can return fast from Pluto? Is is by our own propulsion?

Thanks a lot everybody. smile.gif
Still, is there anyway that a probe from Pluto can apply the gravity assist from Jupiter or Neptune to return to Eath?

Dear ugordan,
You mean the ion thruster? Are they ready for application? I heard that they are still in reseach.

Dear ugordan,
Can you tell me more about the deep space maneuver? Is there any object massive enough for us to use to retarget back to eath?

Oh, I didn't know that. I thought space is filled with asteroids. And by the way, when a probe wants to turn around, its acceleration must be larger or equal to its current velocity, isn't it?

Dear djellison,
I'm just curious about how all the probes can avoid collision. Can they recognise near by asteroids?
Thank you very much.

Uhm, djellison, can you explain more about your idea? I still don't understand it. Thanks a lot.

Thanks for the answer. I guess I can use those assumption for the paper. But for mere curiosity can you suggest a practical way to travel forth and back to Pluto? The one that can be carried out in a next few years....

And how did NASA solve the problems of astedroids? I always imagine that sometimes a probe can be hit by one of these objects?

We can do a Hohmann's Transfer over orbital plane? Great idea. I never think of it.
And, in order to do a Hohmann's Transfer, we surely need powerful thrusts. Is it possible with our current tech?

Is it possible to use pluto's gravity to make a turn like Ulysses?

Hi. I'm new here. I'm working on a school project about pluto. The teacher asks me to design a space trajectory for a spacecraft to travel to pluto and return to earth. I have no ideas what to do. Please help me...
