WRESAT and Sparta

[JakGamingKSP]

Hi in 1967 Australia launched their first sat WRESAT now I challenge you to build wiki page-https://en.wikipedia.org/wiki/Sparta_(rocket)

only mod FASA if you do want to use FASA ask me ( note-Third stage was in wresat)

Seems straightforward enough. I'll do it!

I love replication challenges. One thing you can do to make them more interesting, though, is to list off the various characteristics of the given vehicle and assign scores to them. For example, for Sparta+WRESAT, point-contributing attributes could be any combination of these:

• Three stage
• Cone-shaped, battery-powered satellite
• Satellite does not decouple from third stage
• Enough battery power for five days
• Polar orbit
• At least two scientific instruments
• Unmanned
• Single-engine, non-gimbaling liquid first stage
• Aerodynamic guidance only on first stage
• Solid-fueled second stage
• Solid-fueled third stage

Just something to think about!

Okay, here's my entry.

I did use Tweakscale to make the structural fuselage large enough to match; hope that's okay.

I had to keep nerfing parts with tweakables because otherwise I was getting into orbit on my first and second stages.

Spoiler

Lifting off.

I nerfed the Skipper and cut out over a third of the fuel at launch to avoid doing an accidental SSTO, so acceleration was VERY slow.

Inching toward a gravity turn.

Kept it pointed slightly west so I would cancel Kerbin's rotation.

Nearing burnout.

Staging! As you can see, fuel load in the Antares-2 second stage is low as well.

Still makes a pretty picture.

Separation while still suborbital for proper disposal of the second stage.

I used a maneuver node in the hopes of eliminating any overperformance.

Circularization.

How's that for a gorgeous polar orbit? And on two solid upper stages to boot.

Fairing jettison (note: this part kinda sucked; there was no way to do a proper conical satellite).

Extending the antenna!

Nothing like some delicious Gravioli readings.

This science info was kinda pointless....

Barometer readings! Because vacuum!

Sending the data home!

Taking some readings above the South Pole.

Doing the same above the North Pole. 

Ran out of battery power after just two orbits...oops!

Anyway, there you have it!

Oh shoot! Now I have to redo it. Completely messed that up.

WRESAT used a Redstone launcher? Wow, that's really surprising, Redstone was a balistic missile (before it became a Rocket booster) after all!
It surprises me that US agreed to gave one away to Australia (those must've been highly sensitive/classified in the '60!!).

Hmmm it seems even wikipedia agree:

Thanks for sharing that @Martian Emigrant

Cool Thx so Just so you know the 3rd stage was smaller and was fitted in the sat
