# BugMultistage 2015 Vessel not being able to get into Orbit.

#### DDasng1352

Hi,
As the title says, I can't get into Orbit using multistage 2015. I'm currently using Orbiter Beta V190914 or R90. Please, if you can, let me know what I can do.

What do you mean? Does it run out of fuel before getting orbit?

It has enough fuel, but the guidance seems to not work.

#### DDasng1352

It also looks like the rocket is pitching way to much.

Basically the rocket point forward and does not pitch up or pitch down. Roll program works.

It makes sense. If you run the 2015 edition of an addon on a post-2016 version of Orbiter, you are likely to run into problems. Because the sets of instructions that are part of Orbiter's core have changed a bit, and some functions simply don't work the same way.

I tested MS2015 in orbiter beta r90 and everything works correctly except the MFD. I recompiled the MFD here and with that installed the SLS that comes with MS2015 works just fine. Roll, Pitch, and perfect orbital insertion. I think something with your launcher or guidance file is all fouled up.

I am not sure if related but I tested a scn with the same guidance. And the orbits were different between d3d9 and normal graphics:

-30.000 =orbit(425,437,28.45,-1)

The default graphics shuttle orbits ok. while the d3d9 hits the atmosphere

Hmm. Maybe much higher frame rate has something to do with this?
When I tested this, I just set up a quick and dirty beta install just to test this (I didn’t want to mess with my NASSP install!) so I didn’t bother to install D3D9.

I'm randomly using the Multistage Sat 1b made by @4throck and using it on AMSO extensions.

Hmm, I can not imagine how the graphics client would change the guidance.
I noted that the inclination is a bit different between your two launches. Could be, that during the D3D9Client the (Orbiter) core had more time to "add" wind effects - affecting the launch profile more? Just a guess.

So here is default sts57 launch in orbit

and d3d9

with the guidance file:
orbit(402,471,28.45,-1)

presskit:
Orbit/Inclination: 250 nautical miles/28.45 degrees 463KM = 250nm
