Would it be going above and beyond to do this on ps4, and a realistic lv?

Yes

Alright, so I went with a Voyager remake. I tried to make my probe look as much as the original and also, I tried to launch it with my version of a Titan IIIE Rocket. Because I cant fold up my probe, the fairing obviously doesn't look original. I have to say - it's a strange rocket. It has giant SRBs and a tiny second stage.

Also, I didn't achieve Kerbolar Escape, just a 1080 year eliptical orbit.

Sorry got carried away with making a KSP alt history roleplay group and irl stuff to do the challenge, might actually get back to it however im using KSRSS

KSRSS is OK

[IntellectualTortoise]

Thanks for the challenge @Akagi! Here's my modded Viking replica.

 

Game version: 1.12.3, Stock + both DLCs

Mods: Click Through Blocker, Kerbal Engineer Redux, Module Manager, Spacetux Library, Stage Recovery, Restock, Restock+

 

Mission:

Spoiler

Titan IIIE-Centaur rocket in the VAB

 

On the launchpad

 

Liftoff

 

SRB separation. I chose a more vertical ascent trajectory due to low TWR in the second stage.

 

Second stage ignition after fairing and first stage separation.

 

Centaur third stage accelerating the spacecraft to orbital velocity.

 

The remaining fuel in the Centaur is used to begin the Duna transfer burn.

 

The orbiter's engine finishes the transfer burn. In reality, the Centaur stage completed the entire burn.

 

The Duna orbit insertion requires all remaining fuel in the orbiter.

 

In elliptical Duna orbit

 

Map view showing orbit. This orbit is just the lowest I could get with what fuel remained in the orbiter and is not intended to be historically accurate.

 

Jettison of the cap of the "bioshield" -- a pressurized and sterilized container in which the lander was stored during launch. In the actual mission, this cap was actually jettisoned immediately after the Mars transfer burn but I didn't find out about this until afterwards. In addition, part of the bioshield also remained attached to the orbiter.

 

Orbiter-lander separation

 

Lander deorbit burn

 

Lander parachute deployment

 

Touchdown successful!

 

Lander with antenna, science instruments and "robotic arm" deployed

Sputnik 1 (LKO)

Hubble Space Telescope (LKO)

JWST (HKO around Minmus's orbit)

ISS (LKO)

Apollo 15 (Mun)

Apollo 11 (Mun)

Curiosity (Duna)

Juno (Jool)

Voyager (flyby of Jool to Kerbolar escape)

Luna 16 (Mun)

2. Land one of the following on its target body.

3. Submit your ship! Required screenshots:

3-A. Your ship in the VAB, with part count and mass.

3-B. Your ship on the launchpad.

3-C. Your payload in the target orbit. (For lander: Your ship in orbit of the body to be landed on)

3-D. Your lander(if used) on the target body.

 

Badge (any completed mission)

Featherweight Badge (any mission below 10 tons)

Above and Beyond Badge (exceeding requirements, i.e. realistic launcher, realistic orbit, etc.)

Please note: Every time you do a mission, you get a badge.

MODS ALLOWED

• DLCs are, of course, allowed.
• MechJeb and other autopilot mods are allowed.
• Ask before you use a part mod.
• Mods that actually add any of the ships above are NOT allowed! That is classed as cheating. A major part of this challenge is the creativity needed to create these replicas.

[Aswe23]

While it wasn't on the list, I decided to fly a replica of my favorite spacecraft,  Surveyor 1, the first American lunar soft-lander.  Just flying a lunar lander was a bit easy (especially something as small as my Surveyor replica), so I also built a replica of the Atlas-Centaur 10 booster. Most of the craft is historically accurate, down to the RCS thruster placement on the Centaur stage. I did have to do a bit of part clipping to get the Atlas looking and flying right, so hopefully that's ok. 

Mods: ReStock and just about every visuals mod I could get my hands on, as well as Trajectories so I could time the descent burn. 

In the VAB. I tried to get the lengths of the side cable runs and electronics bays right for an Atlas-D, but they're not perfect. The launch clamps are more or less where the Atlas vehicle was held down. 

On the pad, ready to make history.

Ascent. In the historical orientation ( -y axis pointing downrange) the rocket is very unstable, and I had to clip 4 small fins into the lower booster so it didn't tumble during the gravity turn. 

Just like the real Atlas, this replica has a stage-and-a-half booster, where the external engines are discarded while the core engine carries the half- empty rocket onwards. 

Stage 1.5 burn, getting into a suborbital trajectory.

Just like the real Atlas, the core engine is shut down early and the LR-101 vernier thrusters are used to ease the rocket up to its target velocity (fun fact: this feature is left over from the Atlas's ICBM days, where a very precise final velocity was required)

Centaur separation

Ullage burn prior to Centaur ignition. The RCS locations are based on this diagram for Atlas-Centaur 10 and are almost historical ( I didn't bother getting an exact 25 degree angle for the roll jets )

Injection into a direct impact with the Mun. I substituted in a big solar panel in place of Surveyor's planar high-gain antenna for looks. 

Centaur separation.

Firing of the STAR-37 retrorocket. In the real Surveyor, the retrorocket is recessed into the structure of the lander, but due to the size limitations of KSP's stock solids I had to make do. 

After being slowed to near zero velocity, Surveyor ignites its vernier engines for the terminal descent.

Pretty.

At an altitude of 5 meters, the velocity is brought to zero and the engines are shut off to prevent contamination of the surface.  The last 5 meters of freefall result in a 3 m/s touchdown velocity.

And touchdown of Surveyor 1, the first American lunar lander!

 

Hopefully this isn't too far away from the intended list of missions to be included, and apologies for the long post, I just had a lot of pretty pictures

Thanks for starting this challenge, it was really fun! I might take a stab at Luna 16 soon!

Wow! Take an Above and Beyond badge, for sure!

[Akagi]

Rule update: you can make any craft you want as long as it is a real craft.

[mmiillmm]

Second try of making the Sputnik-1! I'd still love to make the side boosters better, but I don't really have any parts to do so. I hope this suffices!

 

Rocket in VAB


 

 

 

Liftoff!

 

 

 

Beautiful shot

Do I get a badge now? O.O

[Snigel]

I present my replica of Explorer 1, the first satalite launched by the U.S.

mods used are Restock and Restock+

The satelite itself. I wouldv'e liked for it to be a narrower like the real thing, but this was the best I could do.

the asembled "high speed stages", notice the layerd clustering of SRBs.

 

The completed rocket with the Juno 1 booster in the VAB.

 

A few shots of the flight:

 

the finished probe, containing "thermal measuring ecuipment"( a 2HOT thermometer), just like the real thing.

My second entry: venera 11

lso done with restock and restock+

The pronton K/D launch vehicle was slightly downscaled for practical reasons.

[Akagi]

@Snigel you get the Above and Beyond Badge, and @mmiillmm you get the standard badge. Enjoy!

[Kimera Industries]

It's not on the list, but what about the Galileo spacecraft? I could also do the atmospheric probe. I've always wanted to send something into Jool.

Spoiler

The high gain antenna won't get stuck like the real thing, haha!

[Kerbalsaurus]

@Akagi

Will ReStock still be counted as Stock, or is it still a mod? It's technically a visual mod, not a part mod.

[Akagi]

ReStock isn't a parts mod so I'll let it slide
