"Rosetta" -- A KSP Short Film, and Its Explanations
Wavechaser replied to Wavechaser's topic in KSP Fan Works
It should be good right now. I fixed the embed code thingy. At least it works for me. -
I know this is a few days later than the actual landing, but hey, it's here afterall. I spent a week recreating the mission and record it. I finished putting it together three days ago. OK, this is the video you guys are looking for. If the embed thing doesn't work for you, click . If my video on YouTube happens to be blocked in your area, I'm sorry about that. But don't be sad, I've also got you covered. So let me do some explanations regarding this mission. I recommend you to watch the video first, so at least you know what I'm talking about. (If you don't see the embed album, click the link on the right) http://imgur.com/a/srtLN#0 I am not going to post the pictures one by one, just because they're huge. -- This is about Rosetta: I have four KW's 1.25m tanks clipped inside the metal frame, to provide fuel to the engine. I also have a reaction wheel, some batteries, and some monoprops inside the frame. That's basically the body of the Rosetta probe. In tradeoff of the fuel, I don't have much space left inside the probe for Philae lander. It was hanged under the probe body. I used an IR hinge to move Philae before separation, so that it wouldn't glitch or explode. In the "fold-up" state, it is actually partially clipped inside the Rosetta probe. You might have noticed, I've got a KAS magnet underside Rosetta. It's used to stick the probe to the asteroid when Philae performs the landing. Erm, that's all about the probe that I can think of, ask if you want to know more. -- This is about Philae: Yep, it is the three-legged little probe lander that made history. Even some failures occur in real life, it... ...still did a great thing. In my version, it does have solar panels that cover a half of the probe body, a grappling hook, and some science equipments. The real Philae has two sets of grappling hook, which I only have one; and the real one only have one cold-gas thruster. I used two RCS ports to resemble the thrusters, which will more or less help it move around. It does have a DMagic drill thingy as a part of science equips. The only thing that my version doesn't have at all is the screw on the landing legs. It does have a small 0.625m monoprop tank clipped inside the probe core for the RCS. Again, that's what I can say right now, just ask if you want to know more. -- This is about the rocket: It does have two SRBs, one liquid core stage. It does have a little bit too much Delta-V, from the separation of the core stage 1 to the end of orbital insertion burn, the second stage still have a bunch of fuel left. The last stage, the Solar Trajectory Injection Thruster (STIT), also have too much fuel, it can push the whole thing to escape velocity with 35% of fuel left. There's isn't really much about the rocket, it's just... ...a rocket, pretty straight-forward. -- This is about the comet, 67P/ Churyumov-Gerasimenko: I used FASA Asteroids for that. Two reasons, first, it has some gravity, so the landing will be more realistic. And second, its size and shape are more controllable than stock asteroids. Yes, I once tried to edit the config file of stock asteroids, and turns out, their shapes and sizes are never controllable, it basically procedurally generated into random shapes. In addition, you can't stack them. They will blow up on the pad. I mean, literally, blow up, all over the place, sky-high, [just like this] . So I decided to not mess with them. The only bad thing about FASA Asteroids is their gravity won't work under any time warp. (Not physical warp) Ast. 2687 "Ã…Â teins" and Ast. 21 "Lutetia" are from FASA Asteroids pack as well. And, I admit that I did use Hyperedit to put them into solar orbit. Well, who would want to put a thousand-ton thing into a solar orbit which has a apoapsis beyond Jool's orbit? -- And I'm gonna be really nice and give a list of mods I used: Core Mods: KW Rocketry Near-Future Solar D-Magic Orbital Science FASA Asteroids Procedural Fairings KerbCam Mechanical Jeb Station Part Expansion Hull-Camera VDS Infernal Robotics Kerbal Attachment System Auxiliary Mods: Trajectories Active Texture Management TweakScale Tweakable Everything Toolbar Plugin TAC Fuel Balancer Part Catalog OK, I guess that's all.

True, but if it simulates every body in the Kerbol system, the game would most likely crash as soon as it loads into your saves. Plus, patched conics is good enough for KSP.
-
Even the L points don't really exist, the points right in front/back of Kerbin, and share the same orbit with it, would be extremely useful for communication relays.

Ultimate (Stock) Lifter Challenge
Wavechaser replied to Bioman222's topic in KSP1 Challenges & Mission ideas
Does speed really matter? Since the ideal condition is following the Vt. Plus, the "best looking" really varies by people, so you can't just say that. And also, how about the informational mods? Like engineer, MJ, etc. Or those like FAR, NEAR?? Then cost, if the craft components are recyclable, they will that reduce the final cost? -
Why use the arospike
Wavechaser replied to Apature rocket science's topic in KSP1 Gameplay Questions and Tutorials
It's indeed useful for Eve ascend purposes (get out from the bottom of Jool's atmosphere isn't really useful and is extremely hard), and small SSTOs. But after the introduce of the RAPIER, many people gave up on it. Still, I personally like to use it as the rocket on SSTOs instead of RAPIER or sometimes even SABRE (B9). And also useful for vertical cargo SSTOs. One thing that's bad about it is it doesn't have gimbal device. -
I am very not happy about the all-stock policy. B9, KW, ProcFarings, ProcDynamics, FAR/NEAR are all good stuffs to have... ... (NF and Interstellar Packs are indeed good, but their engines with insane Isp may be considered cheating)

Why use the arospike
Wavechaser replied to Apature rocket science's topic in KSP1 Gameplay Questions and Tutorials
You won't say "it's just another rocket engine" if, if you take a look of its specific impulse. And compare it with LV T-45 and some other engines. 388s/390s (atsp/vacm), man!! 388s in ASL! That's almost as effective as LV-909/Rockomax Poodle/KR-2L in vaccum! I know it is kinda ugly and can't be attached in the bottom, but, hey, it's extremely fuel-effecient. In fact, it has the most ASL specific impulse among all the stock engines. Plus, 175kN of thrust is fairly a lot. -

What input device(s) do you use with KSP?
Wavechaser replied to PhaserArray's topic in KSP1 Discussion
Trackpad, keyboard. Sometimes I use mouse with Windows laptops. -
Eve and Gilly exploration contracts, one mission. (late career)
Wavechaser replied to moogoob's topic in KSP1 Mission Reports
Um, its Vt is somewhat like 80 m/s, not 80 km/s. -

Too fast landings
Wavechaser replied to bartekkru99's topic in KSP1 Gameplay Questions and Tutorials
Go get B9, and use its airbreaks. -

No B9? What... ... -
"Litho" is rock, which basically means you will... ...um... ...stop as you hit the ground... ... Um, there were actually some real-world missions use lithobraking technique, for example, MERs (Opportunity & Spirit), and the Russian Venus landing missions. You might need to search for some airbag mods, which I know Lionhead Aerospace makes those, but the MER ones are still under development. Check this, it might help: https://en.wikipedia.org/wiki/Lithobraking

Look, why don't you add a Mark-2 size reaction wheels like those in B9? Or let Squad do it, since it combined into the game... ...
