The KSP Interstellar Proxima Centauri Challenge

Recommended Posts

For breaking speed you could also use the (bussard) magnetic nozzle, it is capable of producting a lot of drag without heating effects, and is throtable, so you have some control. but it only function above the atmosphere.

A low tech solution would be to make use of ballutes.

Break is not a problem the ship break until zero horizontally with no issue.

Actually found 2 solutions to do the refuel:

  1. Brute force from 80 to 200 km using 4 packs of 4 NV-GX, semi-worked, the forces at the end or so big the ship exploded, maybe accelerated to much at the atmosphere.
  2. Don't go below 200 at all just at 220km is enough and in a elliptic orbit to allow a fast correction at "AP" if needed.

I can say now that the last detail to close the issues list:

  • Still RCS final wheels (to avoid unwanted rotations, without using the engines to control the spins)

The goal is done all individual parts and phases of the ship were tested: following some demo videos of some parts.

This video belongs to a collection of videos that will describe an Interstellar Journey to the near Star:
- Using the physics Simulation "Kerbal Space Program" and "KSP Interstellar" mod
- Alfa Centaury, planet "Von Broun" (of Centauri Dreams mod adapted to work on 1.7.3)
- The max potential acceleration speed of the ship is 105 Mega delta-v m/s 35% speed of Light

InterStellar SHIP version: "Daedalus_and_Bussard-v3_2-Kerbin-tanksEmpty.craft"

humm... strange never saw that nice Exhaust ...

well that is becaue I'm trying to add it, which is not trivial. The main problem is that not easy to scale an exisitng exhaust effect. To achieve above effect, I downsized the Daedalus to 0.625m and then rescaled it up with tweakscale to 5m. It works but the default Engine size will be 0.625 instead of 5m. Of cource is you will scale everything anyhow, that will not be a problem, but some people like to keep thing unscaled. It also looks weird in the Part Catalog where you have aprt with only 1kN of thrust, which is low, but becomes 3000kN when scaled up to 5m

@pmborg When using a Daedalus for transfer to Jool/Jupiter,  you realy don't have to conserve fuel durring transfer, you can spend 100000 dv to Jupiter and don't feel sorry about it.

Are you using realplume?

Not yet, but I'm investigating if can can achieve what I want to achieve

An alternative might be

  • "Daedalus_and_Bussard-v3_3-tanksEmpty.craft": Pretty much almost the final version:

rD1rRpH.png

Notes:

  1. - The max potential acceleration speed of the ship is 105 Mega delta-v m/s 35% speed of Light
  2. - (with refuel on a planet  can go more 87 Mega delta-v ), if we decide not de decouple Scoops.
  3. - Stage 1: Go Orbit (Kerbin or Earth)
  4. - Stage 2: Do the first 18M delta-V
  5. - Stage 3: Do final aceleration 87M delta-V

 

  • Factory Tank with "Kit Container":

Useful Payload: (Capsule to be delivered on Von Broun Planet of Alfa Centaury)

acXdxXN.png

- Notes:

  1. The Payload can "fly" if needed (electric, infinite range)
  2. InterStellar Crew made for 6 pax with 100% life Support.

 

 

  • "InterStellarHouse.craft" (Inside KitContainer)

t69YEc4.png

House made for 6 pax but can hold in 100% life Support for max: 8

- Note:

  1. the house can "fly" if needed (electric, infinite range)
  2. the Car have a docking port with the House for parking and refuel

 

Additional Notes:

  1. refuel on Jool (stock planet) can be done safely between 250 and 200km height
  2. refuel on Saturn (RealSolarSystem Mod) can be done safely between 2000 and 1600km height

 

Additional Features (that are being Study):

  1. The interStellarShip will be on orbit of the planet, ready to be used again if need.
  2. On ground factory, make a rocket that will do a Rendezvous with InterStellarShip (on stage 3)

 

What do you think @FreeThinker ?

Where is the Science Lab?

-The science lab is one of the components of the payload that will land, can be seen up the FactoryTank in image

-Payload, Tank and the House will be linked with KAS for share resources

What about resource scanning and collection and ISRU. KSPIE Has a universal drill that can collect surface collectable resource. Also include several  IFS Switchable Storage tanks to hold collected resources.

Hello,

- Resource Scanning is there not appear on images: (opposite side )

X8BPItz.png

 

About the Universal Drill yes also there: (Oposite-House-Side):

rqd87rN.png

 

About the Tanks are not there on propose, please note that I have a factory and can do what ever I want over there.

  • Right now my payload is about 600tones, don't want to go further than that
  • Have 2 versions of the ship 105M (35% speed of light) and 125M (41.666% speed of light)
  • My dream goal is to have a 570M i.e. go 95% speed of light and break from it.
  • I am studding crazy possibilities to rich that I think that is possible.

 

I record a video of 30mins do show/demonstrate the payload and house working but discovered that the payload is not balanced after tank leave the payload bay (cannot fly balanced due center of gravity changed)

THe only way to achieve that is go antimatter or use a black hole. You could also achieve that with Laser but its only realy feasible for probes, Kerbals would  get squiched, but you could use as scouts to figure out the best candidate for a interstellar colony

  • I am studding other more realistic, ways :) using asteroids and trying to merge them with current ship.
  • Basically I am talking about "almost" infinite fuel and only using things that already exist on KSP.

Ok, but how did you get it there?

Regarding Equipment, why not use extra planetary launchpad mod, and therefore have maximum flexibility.

  1. Went with a balloon type over there at that position

Yes this can be one of the possibilities, but with the way that I am doing it, I don't need that mod and in practice do the same.

Well one of the reason it might be preferably would be to minimize part count as you would only create the part once you real need it, and there will be plenty of time. Also take into account, you going into at he big unknown, who knows what you need on the other side.

  • Yes that's the pretty thing about "Kit Container", that's why I am using it, I can put over there what ever I want (300 or 600 parts) and will count only with 1 part, until being constructed.

 

  • So I have 1 "Kit Container" with the Car+House+"Assembly line" inside
  • and 1 Tank-factory (mobile factory) only, that
