My space travel

[Izack]

At the distance of about 20,000,000,000,000 kilometers or about 164,000 AU or little over 2 light years away from the sun, the spacecraft experiences no gravity from the sun at all!!

Not entirely accurate. You're experiencing no perceivable acceleration due to the Sun's gravity, but the Sun is still your primary gravitational influence, and the focus of Orbiter's universe. :tiphat:

Actually, you do experience (assuming the ship's mass is negligible, and it is, unless you're flying something the size of Jupiter):

gravitational acceleration = gravitational constant * ((Sun's mass)/(distance^2))

g = 6.67300 * 10-11 m^3 kg^-1 s^-2 * ((1.989 * 10^30 kg)/((20,000,000,000,000 km)^2))

g = 3.318 * 10^-13 m/s^2

which is far too small to have any real effect, but it exists. In fact, no matter how far you go, you'll still feel the Sun's gravity, albeit almost not at all.

Hi, Izack!

@Izack, I think you are right, the sun is still my primary gravitational influence, but as you move farther and farther away from the sun, the sun gravity gets weaker and weaker until about say 25,000,000,000,000 kilometers or about 190,000 AU or about 2.6 light years away from the sun, the gravitational pull of the sun will be so weak, the acceleration of the sun's gravitational pull will be approximately 1 meter per every 50 years or 100 years!

Cheers,
Vincent

Hi, Izack!

Hello! :hello:

@Izack, I think you are right, the sun is still my primary gravitational influence, but as you move farther and farther away from the sun, the sun gravity gets weaker and weaker until about say 25,000,000,000,000 kilometers or about 190,000 AU or about 2.6 light years away from the sun, the gravitational pull of the sun will be so weak, the acceleration of the sun's gravitational pull will be approximately 1 meter per every 50 years or 100 years!

Yes, but this isn't the effect you would see in the gravitational soup of the real galaxy. (Instead you would have negligible acceleration from several bodies at once. )

i think its good that the interstellar type vehicles are getting the attention they need. i have to admit i never use them

fastest speed

Hi, guys!

What is the highest speed you guys have reached with limited fuel unchecked in orbiter? Right now, I'm traveling at 139,792 kilometers per second with limited fuel unchecked! Thanks!

Cheers,
Vincent

[Izack]

Does NaN count?

 

[MaverickSawyer]

oooh... are .cfg mods allowed?
*opens a velcro rocket .cfg and begins adding zeros...*

 

[Pipcard]

And then your HUD shows the number, with no units, crossing over the boundary of the green box.

What is the highest speed you guys have reached with limited fuel unchecked in orbiter?

Kind of a pointless challenge as with unlimited fuel and Newtonian physics you don't have much of an upper limit... until the you overflow the scenario values and cause a CTD.

A better (and more kerbal-esque) challenge would be 'How fast can you go with limited fuel on by building stuff out of velcro and other parts....' :lol: starting from the surface of earth of course!

 

[Hielor]

Just land on the sun and you'll get a nice speed boost.

I think that would be a challenge equal to: Who can find the best launch window to do xx slingshots in one flight?
Which would be one for dgatsoulis.:lol::thumbup:

 

[Yurik]

2,5 c lol :lol:

 

[sorindafabico]

Is there any add-on that fully simulates relativity? We would have a nice "who got closer to light speed?" challenge.

 

[vinny5000]

Hi, guys!

Right now, I'm moving at the speed of 161,500 kilometers per second, and the distance of 423,500,000,000 kilometers or 2,830 AU away from the sun!

Cheers,
Vincent

Dang. How have you not crashed the physics engine? :blink:

 

[jedidia]

Dang. How have you not crashed the physics engine?

Not a problem, I've been further during Orbiter Galaxy testing. One thing that happens at this distance though, is that the game crashes on reload if you don't shut down tha hud at this distance, and you'd better don't try any dockings... :shifty:

 

[vinny5000]

Hi, jedidia!

I'm now moving at the speed of 163,700 kilometers per second and the distance of 435,110,000,000 kilometers or 2,909 AU away from the sun, then I turned on,off the HUD, then I switch to different HUD modes like surface, orbit, and dock and then I turned the HUD off and no problems whatsoever!

Cheers,
Vincent

 

[jedidia]

Not what I meant. Exit the game, and load it again. Without deactivating the HUD. If it doesn't crash, you're just not far enough. I was several lightyears out...

The docking problem is not related to the HUD, but the limits of the double data-type. Just do an EVA at this distance and try to get into your airlock again. You might find the maneuvering somewhat... twitchy.
