Voyage to the Sun


Recommended Posts

So with all the new content coming and with all the new features that will be implemented in the next version of KSP (as of now v0.16). I was just speculating to myself, wondering, dreaming so to say, about what other possibility\'s of KSP could hold.

One thing I\'d really like to see is the expansion of scientific stuff ;D, finding out more about the solar system. Being able to study planets with sattelites and sending rovers. Anyway, in this daydream I decided to travel.......to the Sun :o!!!

As far as I know no-one ever tried this before, and I can honestly say, its not really that awsome. Secretly I was hoping for some kind of easter egg like the center of the galaxy in Spore as reward for travelling so far:

So I was curious as to what would happen would one fly directly into the sun ;P

Turns out the sun is a big hot thing that burns your spacecraft if you get to close, it just so happens that it has a big gravitational pull and emits a lot of light. Nevertheless it was a fun little adventure.

And the coolest thing is, I think I may have broken some records in the process for overall distance travelled and highest speed achieved. And that is where my challange comes in in the hybrid suggestion for the dev\'s/challanged topic (dev\'s if you read this what I mean by that ofcourse is that I would like to see functional sattelites etc).

Anyways, I would like to see what you guys would do to get to the sun. What kind of vessel did you use, what speeds did you achieve, let me know!

Here are some screenshots that discribe my journey and the records that (I think) I broke:

For my rocket I used only parts found in the Novapunch remix pack. It consisted of:

#1 stage: 2x FL-T300 fuel tanks, 4x TiberDyne JF-1750 Solid Boosters, 1x 3M7X1 adapter plate with 7x M-50 Liquid fuel rocket engines, 1x RCST-300 RCS tank with 4x RV-105 RCS thruster blocks.

#2 stage: 2x HH-78a large fuel tanks, 1x NERVA Mk. 1 Nuclear Thermal Rocket Engine, 1x RCS-175 RCS tank with again 4X RV-105 RCS thruster blocks. Then a M-38 unoccupied guidance system (we wouldn\'t want to burn our kerbals now would we ;) ) as guidance. A vanilla Advanced S.A.S module, and a Platinum Communications Model BXs-9 for 'gathering scientific results'.

Some statistics

Total mission time: 34 days, 17 hours, 11 minutes, 19 seconds

Highest speed achieved: 182.535 m/s, or mach 536.41 at sea level, or 0,060845% the speed of light.

Total distacne travelled: 31.417.724.130 m, or 1/301129,3867th of a lightyear.

Mind you, I deliberetly crashed into the sun because I wanted to see if it looked any diffrent up close, and what would happen if I would get really close. You can probably get higher speeds if you get in around an orbit.

One more thing!! If you plan on trying this yourself, I suggest taking off at noon, when the sun is directly above your space craft. That way you only have to go straight up making maximal use of your fuel, and you don\'t need to preform any complex allignments.

You actually get best use of the fuel by smoothly going into low orbit first, and then burning at the point where the limb of your planned hyperbolic escape will take you in the correct direction. As mechjeb\'s acnet stats will show you, this minimizes the gravity drag, for a more fuel-efficeint departure.

If you /really/ want to save fuel on a sundive though, you need to do a Bi-Elliptic transfer. Leave out the leading edge of Kerbin\'s SOI for a very distant apoapsis (I usually go for 131 GM from Kerbin orbit). Gravity drag will slow down your ship for you, leaving you with a lot less velocity to kill when you get out there. From Kerbin orbit, a Bi-Elliptic sundive can cut the required delta-V by half, at a cost of a trip that takes dozens of times longer (My typical bi-elliptic Sundive is a 1200-day trip). In fact, the numbers work out that it\'s more fuel-efficient to go the bi-elliptic route to sundive from any distance more than about 6 radii from the star.

This was actually one of my first attemtps at it. The ship is fairly poorly designed, and I start burning to exit the leading pole of the Kerbin SOI too early, and compound the error by wasting fuel trying to bend my trajectory in LKO. This was also in version 0.12 something, where, like in the Demo Version, the sun doesn\'t yet have the kill line added in 0.14, resulting in a maximum velocity of about 4000 km/s at periapsis.

I have no idea what you are talking about, but I believe you :D
