  1. I think I saw a working imgur album earlier. I must test this. Neat, it auto-embeds the direct album link.
  2. Did...did they fix embeded imgur albums?! Is that what those 502 errors were about?
  3. I like how the one on the right kinda looks like a squid.
  4. Yup, even those famously re-usable SRBs got utterly worked over by the salty ocean water they splashed down in. The things even managed to suffer enough electrolytic corrosion that some design shenanigans took place to reduce it.
  5. Nah, theory might be better in this case. My experiments (that at all succeeded) have been fairly limited, one or two full small ore tanks or less payload, that 1291 number was a single kickback under a hammer under a fairing with mini decoupler, two small ore tanks, a hex and a z-100 on top. 'Biggest problem was trying to fly the crazy things -- such a rocket no longer turns for love or money once the booster's anywhere near burnout -- most likely my ascent profile is insanely sub-optimal. A PAM's an SRB upper stage, intended for vacuum use, usually boosting a payload up to an intended orbit or out of the SOI, like the STAR-48 motor used for New Horizons. For some reason they keep packing a bit under 1km/s delta-v with arbitrary dense payloads I've selected, and are of course very cheap (seperatron PAM's arguably the cheapest way to circularize small probes if the resulting orbital parameters don't matter much).
  6. I did a few tests with SRBs and hyper-dense payloads (small, full or mostly full ore cans) in 1.25m fairings. 'Found that the lame ol' Thumper is actually very convenient about its mass/drag profile during an ascent from an initial tilt on a launch clamp, and can just about make it out of the atmosphere in a normal gravity turn. The Kickback is of course more capable, but a lot less stable, needing a few fins in back, which required greatly reducing the pad tilt to halt lawndarting. It was also a lot angrier, blowing up said fins almost invariably when trying to pick up horizonatal velocity. Best result was 6.6 tonnes to a very low orbit for 1291/tonne using a Hammer for a Payload Assist Module, 'found that said 7.2t payload was about as much as one can get away with on a single kickback, as the turn gets too aggressive, nearly blowing up the fairing. A similar design using a Spark instead of a PAM did more poorly, failing to make orbit due to losing too much speed to the atmosphere after MECO, or not get enough horizontal kick out of the booster and running out of gas in the 990m/s upper stage and just not getting the periapsis up.
  7. Not quite, you forgot the 4 significant digits. 2.789 * 299792458m/s should be rounded to 863100000m/s. Roughly. *suffers flashback to highschool chem class*
  8. Roughly. Likely a case of a vast decimal rounded to 4 siggies for sanity.
  9. Sounds like for disposables the way to go might be a well-tuned, dense, payload of ore and a nosecone atop a carefully tweaked kickback. Possibly with a flea-based PAM for circularization. Heck, if you're gonna PAM, you could go partially disposable -- toss a couple of chutes on the kickback, get the apo a decent ways into the future, splash down the kickback, then pop the PAM near apo. Perhaps the amusingly low-drag (and fairly cheap, I think?) juno intake could be leveraged nosecone-ways.
  10. Yup, it's a goodly chunk bigger than the Jool system, but not 10x the size. Conveniently, there's about 300 Mm in a light-second, and Pol's apoapsis is only 210.624207 of 'em, less than the semi-major axis of Trappist-1 b, which orbits at 5.555 ls or 1666.5 Mm, but more than a 10th of it. Bop's orbit would still be just inside a 1/10th-scale Trappist-1 b's, though. Numbers are weird enough that these three conversions are pretty good for thinking about scale: 500 ls/AU (seriously, almost exactly 499) 150 Gm/AU (almost exactly 149.6, what) 300 Mm/ls (almost exactly 299.7996, this is getting out of hand) Amusingly, this means the 12 Mm distance to the Mun would result in a nearly imperceptible .04s signal delay with Mission Control.
  11. Hehehe, yup: relevant forum thread. It can be done with stock parts, preferably with the help of Kerbal Alarm Clock to avoid having to babysit burns. That link goes to a post regarding some monster I created, having taken the problem as a bit of a challenge, but you may find the whole thread relevant to your interests.
  12. Real should suffice. That system is dang tiny -- converting the orbital distances to light-seconds (any Elite: Dangerous players will be able to get a feel from these, I just multiplied the AU given on the wiki page by 500, but there's actually 499 per AU): planet semi-major axis in light-seconds b 5.555 c 7.61 d 10.5 ± 3 e 14 f 18.5 g 22.5 h 31.5 +13 -6.5 Of significant note, Moho orbits at 17.5559 ls, and Kerbin at 45.364. Real scale should do just fine.
  13. No no, no one's shooting a nuclear shaped charge at them -- they're using a nuclear shaped charge to shoot a disk of tungsten plasma at them.
  14. Actually, in 1.2 you can promote kerbs in the mobile processing lab. Also, there's an option in the settings for full-on field promotions.
  15. HEH, 'almost looks like a kerbal HAARP if you squint. KAARP?
