SLS Kexploration Mission 1 (Doing It Orion Style)

Recommended Posts

This mission completed for submission to the EM1 Mission of the Doing It Orion Style challenge.

Only mod was TweakScale. I went a little overboard trying to match all the elements of the real SLS + Orion, down to the count and placement of the RCS thruster blocks. Definitely pleased with the final product, though!

Igniting the SSMEs first.

Booster ignition and clamp release!

I always love these kinds of shots. I don't much like the SLS myself but it is a nice-looking rocket to be sure.

screenshot5.png

Look familiar?

screenshot7.png

Halfway through the SRBs and just now supersonic. Not going to get rid of the launch tower until after the solids are jettisoned.

screenshot9.png

Really starting to get some heating now, right at burnout. Gees will drop soon, though.

Booster staging aided by some sepratrons clipped into the nosecones.

screenshot12.png

Boosters receding; about half my launch fuel and pulling two gees.

screenshot14.png

Throttling down to fine-tune my ascent.

screenshot16.png

Fairing and LES jettison!

screenshot17.png

Now I just need to go a little bit further...

MECO in a disposal orbit.

Separating the core. Nice shot of the ICPS here, compare to this.

screenshot20.png

Extending solar panels as the core recedes.

screenshot21.png

Circularizing. As you can see, I have 13 cubesats mounted around the ICPS decoupler.

screenshot22.png

Orbit circularized. 

screenshot23.png

Testing out my RCS blocks. Note the placement is identical to here.

screenshot24.png

Really good view of the ICPS.

screenshot26.png

Went ahead and threw an antenna on here since it is unmanned.

screenshot27.png

Extending the antennae on the KubeSats.

screenshot28.png

KubeSat 1 away! These each consist of a probe core, an antenna, and an instrument of some kind. I plan to deploy them in low Kerbin orbit, kerbostationary transfer orbit, Munar free-return, and Munar orbit. I only brought 13 KubeSats because that's the number of adapters on Orion's Stage Adapter.

Deploying a few more KubeSats:

Spoiler

Let's see, where were we?

screenshot31.png

Planning Munar Free Return.

screenshot32.png

ICPS reignition! TweakScale is almost perfect, but it didn't adjust exhaust plume length. So it looks a little weird.

screenshot34.png

Deploying another KubeSat with a slightly higher apoapse.

screenshot35.png

Yet another.

screenshot36.png

You can see the orbits of the individual KubeSats.

Deploying KubeSat in Kerbostationary Transfer Orbit.

screenshot38.png

There it is in KTO!

screenshot39.png

Throttling down to finely adjust the free-return.

screenshot41.png

And there's my free-return!

screenshot42.png

Got a pretty good Munar Periapsis for a free-return.

screenshot43.png

Releasing more KubeSats now that I'm in a free-return trajectory. Nice shot of the service module here too, along with the large battery to show I have backup in case the solar panels fail.

screenshot46.png

Approaching cismunar space. Nice shot of the loop around the Mun; you can see that the KubeSats I released have spread out nicely.

screenshot47.png

One of the KubeSats is on an impact trajectory, the others are not.

screenshot49.png

I went ahead and used the ICPS for this burn so I could save some KubeSats for deployment in Munar Orbit.

screenshot50.png

Deploying!

screenshot54.png

Finally separating the ICPS and Orion is flying free!

screenshot55.png

Nice swarm of KubeSats here along with me. Let's head a bit closer to the Mun.

screenshot56.png

Tightening up that orbit...

screenshot57.png

Much better!

Did a few orbits until I was lined up to head back to Kerbin.

screenshot58.png

Getting ready for the return burn. This is the first really good shot of Orion by itself.

screenshot59.png

Starting the burn.

screenshot61.png

And now my periapse is below the surface! This will be hot.

screenshot63.png

Farewell, Mun!

screenshot64.png

Earth approach.

screenshot66.png

Separation from the Service Module.

screenshot67.png

Hope I don't overshoot and come down on land.

screenshot68.png

Very warm.

screenshot72.png

Hitting the drogues immediately to try and get a splashdown.

screenshot74.png

Popping the mains. This is gonna be close!

screenshot76.png

Dropping the heat shield.

screenshot78.png

Cut the drogues.

screenshot79.png

Aaaaand...

screenshot81.png

Splashdown!

@sevenperforce How did you attach the KubeSats to the adapter?

Radial decouplers, tweakscaled down to 60% or so. Each KubeSat is a decoupler, a probe core, a cubic strut, a science instrument, and an antenna.

Great mission! I love the attention to detail in recreating the Orion spacecraft with KSP parts. Even that little strut lattice down by the engine bell... don't think I didn't notice it :wink:
