Community Lead Nerdy_Mike Posted September 29, 2023 Community Lead Share Posted September 29, 2023 October 4th is the anniversary of the launch of Sputnik 1, the first artificial satellite! Weekly Challenge #32: Sputnik 1 Primary: Build a replica of the Sputnik 1 satellite. Sounds simple, but see how detailed you can get! Secondary: Launch your Sputnik 1 replica into orbit around Kerbin. Jeb: Launch it on a replica of the R-7 rocket. Val: Launch your replica into Sputnik 1's historical orbit: Periapsis 215km, Apoapsis 940km, Inclination 65 degrees. Quote Link to comment Share on other sites More sharing options...
The Aziz Posted September 29, 2023 Share Posted September 29, 2023 Good that we can make accurate side boosters with available parts... Oh wait... Quote Link to comment Share on other sites More sharing options...

Yang366 Posted September 30, 2023 Share Posted September 30, 2023 Interesting to see how much fuel we can put in such a 29m-high rocket... ... anyway, reaching the precise orbit consumes a lot of fuel. Especially the 65° inclination... I was not sure about the periapsis argument of the orbit (Pe/Ap position), I chose Pe around the South Pole and AP on the North Pole's side...

PyroSA Posted September 30, 2023 Share Posted September 30, 2023 (edited) What the heck is the right scale for this? Medium is 2.5 diameter right? That would mean this is roughly as big as 4 X200-64s stacked on top of one another and larger than that in diameter (2.5x3+change < 10m). So this was my quick take: More images: Imgur: The magic of the Internet First image was my first take - way overpowered and overfueled - I decoupled just before reaching the target orbit. Rest was from the final launch. Dumped more than half the fuel on the boosters, and 1/4 of the fuel in the centre. Switched to weaker engines. Came in at around 260t and reached orbit with 1500dV remaining. Launched the battery and antennas - roughly 150kg and kinda ball-shaped... No control module, so didn't take a nicer picture of it.

Well at least we have 1.875 meter parts for making it a accurate-ish size... Wait a minute... Quote Link to comment Share on other sites More sharing options...
Antnee Posted October 2, 2023 Share Posted October 2, 2023 Again, so much fun with the nature of this particular challenge. I became sort of obsessed with the overall shape and approximate scale of the original Sputnik launch vehicle, and had to use all of my arm chair engineering skills to fashion some sort of boosters from fairings and chicken wire. Came out alright.... What do ya think? The rocket itself actually performed beautifully, cut perfectly on target and booster separation performed as expected. The only issue I had was the part count of the model got a little out of a hand and started to really affect sim performance during ascent. Twenty eight engines is also a bit much, but the boosters and core stage of the rocket did not disappoint in flight. Quote Link to comment Share on other sites More sharing options...

In KSP-1 we had this in the advanced orbit parameters, but I didn't found them in KSP-2. I found only the Mod "Micro-Engineer" that displays this information. With this, you know when to stop inclining... Then you just have to set PE/AP to the right values, the inclination doesn't change much...
