Sorry but it's clear that you cheated. Just by eye I can say that this launcher doesn't stand a chance.
Another proof:
Your fuel gauge is practically unchanged between those 2 screenshots, despite the significant speed difference.
If you need some advice we can help you, but please don't try to fool us. We did it ourselves, we know what it needs, and if we have a doubt we will try ourselves with your launcher.
To start with, you use too many engines. For your first stage for example, one Titan is largely enough. And with the weight you saved by removing engines, you can add more fuel.
Also, 2 stages is not much for that mission, you should add a third stage. The two first stages are to reach orbit, the third one is to perform the injection burn.
Last but not least, protect your probe with a fairing! The game takes drag into account, and your probe is very unaerodynamic!
Try optimizing your rocket and show us the result.

Dude, you're not serious.
As Noor Nehan says, it's slightly too heavy. But if it was only that, this could be easily fixed, by using a slightly smaller fuel tank, or by adjusting the fuel quantity of one of the tanks.
But there's more to come.
First, this. I assume this is actually not the case, because I recreated the rocket, and with a second engine clipped, it's 6 tons heavier. But that's still fine.
But the most important is this:
From this screenshot, you're at 28.5 km, 371 m/s, and you have 94% of remaining fuel.
First it means that you used a very inefficient ascent profile. And from that point you'll need at least 1300 m/s to reach orbital velocity (not even taking into account gravity drag and the energy loss due to altitude variation).
I can simulate this with my ship design assistant. Those are your second stage's characteristics (when full):
This is the result after a 1300 m/s burn:
It means you can't have more than 39% remaining fuel when you reach orbit. Which by the way corresponds to 1470 m/s of remaining delta-V, far below the needed 1856 m/s, so the challenge is already failed from there.
Now look at what you show us when you reach orbit:
Yet another blatant cheat attempt. I warned you, don't try to fool us, if we can't trust you we just won't award you the badge. You didn't even follow the advice I gave, I'm trying to help you you know.
I posted my own Voyager entry, with a video. I suggest that you have a look at it to improve your flight technique.

Are you kidding me? Third time cheating? What do you take us for?
And you cheated with Altaïr's example rocket.
From here:
To here:
is impossible.
This is actually what happens:
Or a little better, reaching Jupiter.
Reread all the advice you were given, learn how to not fly straight up, make your own rocket, and then post another submission, this time cheat-free!

Well, Mooncrasher beats me to it, but he's right, there are too much inconsistencies in your mission.
There for example:
You run out of fuel at 9000 meters. When I try with the same rocket, this happens around 7000 meters:
Your rocket is surprisingly slow too, 109 m/s is really few at that stage, and with your boosters now depleted, this will require a lot from your main stage to reach orbit. This is a very bad start.
Then, this:
From the gauge, you seem to have something like 60% of remaining fuel, which gives you around 1186 m/s of remaining delta-V. See:
From the needed 1856 m/s from LEO, you already provided around 150 m/s, but this leaves you short by around 400 m/s. Sorry but even with a perfect trajectory, it's totally impossible that you could do it from there.
I'm really disappointed that you just recreated my launcher, added some fuel, removed the fairings (despite my advice), and cheated again.
As Mooncrasher said, it's the third time in a row. I'm sorry but from now on we will require a full non-edited video to accept the mission. I told you not to try to fool us, you were warned.
