  1. Been working, slowly but surely, on what will be one of the final updates to my Apollo project: Skylab. It's still got a long ways to go but as of right now I've almost finished furnishing the interior of the workshop section, and I've taken a few screenshots to celebrate. One of the most recognizable aspects of Skylab was its gridded floor design. At first I had built these floors completely out of light strips, but this alone brought the part count waaay up to ~1400. To save on parts and sanity I decided to instead use a custom flag texture going forward. Under construction From the void, Bob Kerman descends to inspect the station. The forward compartment of the workshop houses a great deal of locker storage and cabinetry. Much of the floor space is taken up by what I presume to be all kinds of neat scientific equipment. Down below, the lower floor houses the crew quarters, including the galley, bathroom, and sleeping compartments. These rooms also contain an extraordinary amount of cabinets and drawers. The opposite side features more experiments, this time in the form of an exercise bike, a lower body negative pressure device, and a spinny chair. It also houses the shower, with curtains pulled up for privacy. From within the device, Bob reports that he can feel a sort of... tingling. That is the sensation of progress!
  2. Thank you! The interstage sections on my crafts are usually just fairings or rings made out of lots of radiator panels and flag parts. For a simpler solution the Making History DLC includes a bunch of structural tube parts which should work well for this purpose. There's also a way to make interstage rings out of one-sided fairings that involves craft file editing. I haven't actually tried it myself but it looks pretty interesting: https://www.reddit.com/r/KerbalSpaceProgram/comments/nf1k1x/editing_the_craft_file_allows_you_to_make_a/gyjccr5/?utm_source=share&utm_medium=web2x&context=3
  3. Thank you, everyone, for your continued interest and support in this project! I'm back once again with what else but even more Apollo missions. Today's update concerns the Saturn I and all ten Saturn I-launched missions from SA-1 to AS-105. These were the very first rocket launches performed during the Apollo program. As its name suggests the Saturn I was the very first member of the Saturn rocket family. It was the smallest Saturn by design, but was designed to be larger and more capable than any other American rocket before it. It was originally envisioned as a three-stage vehicle consisting of a conventional yet powerful first stage with highly efficient cryogenic upper stages. The first stage in particular would utilize a unique clustered tank design, being comprised of nine propellant tanks derived from earlier Redstone and Jupiter tankage. This was done to speed up the development and production of the new stage. Altogether the new rocket was projected to feature a payload capacity of 9,100 kg to LEO, ideally completing development and entering service for the US Army by 1963. After being approved for development by ARPA in 1958 the Saturn I was later transferred to the newly-formed NASA for use in its civilian space exploration programs. It soon found its role in support of Apollo. Just months after its adoption into the Apollo program the Saturn I had its first launch in 1961 as SA-1, short for Saturn-Apollo 1. It was an early developmental test flight of the Block I version of the rocket, which only featured a live S-I first stage with dummy second and third stages. This version was utilized to test the first stage while the upper stages were still under development. The prototype rocket performed perfectly during its first launch attempt, a nice change of pace for the American space effort. Two more Block Is were launched in 1962 as SA-2 and SA-3. They both performed very similar missions to SA-1 but also featured an additional objective pertaining to an experiment called Project Highwater. Once the rockets reached their apex explosive charges in the second and third stages were detonated, with both flights releasing 86 metric tons of ballast water into the high atmosphere. Each release created an artificial cloud which expanded rapidly, growing to several kilometers across in seconds. The last Block I flight occurred in 1963 with SA-4. The exterior of the dummy second stage was modified, incorporating ullage motor casings, fuel vent ducts, and external beams to mimic the aerodynamic shape of the real stage. The rocket was also programmed to shut off its No. 5 engine partway into the flight, testing the rocket against a simulated engine failure. SA-5 launched at the start of 1964 and was the first flight of the upgraded Block II version of the Saturn I. For this mission the rocket would finally fly with two live stages, utilizing a lengthened and upgraded S-I along with the S-IV as its second stage. The upgrades to the first stage and the inclusion of its cryogenic second stage greatly boosted the rocket's payload capacity to 17,000 kg to LEO. It carried a ballasted nosecone as its payload and was the first orbital flight of the Apollo program. The next two flights of the Saturn I were used to test Apollo hardware, carrying boilerplate Apollo CSMs along with their LES's, testing the launch dynamics of both components in flight. The missions also used a new mission-naming scheme, starting with SA-6 being designated 'AS-101'. AS-101 and AS-102 both launched in 1964, each successfully carrying their boilerplate CSMs into orbit. Both flights performed similar missions but AS-101 tested the LES' normal tower jettison motors while AS-102 tested the LES' backup separation method, using its powerful escape motors to jettison itself from the rocket. The last three flights of the Saturn I all occurred in 1965, each carrying their own BP CSM and LES. However unlike the previous two flights they also carried large Pegasus micrometeoroid-detection satellites, folded up and stored within the BP Service Module shroud. After reaching orbit the spacecraft would jettison its BP Command and Service Modules, allowing the Pegasus to unfold its large sensor arrays. For years after deployment all three Pegasus satellites measured the frequency and intensity of micrometeoroid impacts from within Earth orbit, continuously returning valuable data in support of the Apollo program. The Saturn I was then retired following AS-105, succeeded soon afterwards by its more powerful younger brother, the Saturn IB. More info, screenshots, and downloads have been added to the main post.
  4. Still on that Apollo train, this time I've added a bunch of the early test missions including the initial set of Saturn IB and Block I CSM flights. I've also reformatted the main page to include more of the early flight history of the Apollo program along with additional context for each mission. However these written sections are still very much a work in progress so... don't read them too hard or anything. Anyways, first up we've got the initial five Saturn IB missions, AS-201 through Apollo 7 From left to right: AS-201, AS-203, AS-202, Apollo 5, and Apollo 7 AS-201 and AS-202 were the first two unmanned flights of the Saturn IB as well as the Block I CSM, which was a basically prototype version of the Apollo spacecraft. They were designed before NASA had decided upon Apollo's lunar orbital rendezvous mission mode and thus lacked the docking ports necessary for the LOR mission. While the lunar-capable Block II CSMs were still being developed the Block Is would be utilized in early test flights, gathering flight data which would be used to influence the design of their successors. AS-203 on the other hand was an investigative flight looking into the flight dynamics of the S-IVB, specifically the behavior of its liquid hydrogen fuel whilst in orbit. This mission involved no CSM and the S-IVB was instead topped with a smaller nosecone assembly. Apollo 5 utilized the Saturn IB to launch the very first Lunar Module, LM-1, into orbit. It was primarily an orbital test on the performance of the lander's ascent and descent stages as well as their individual propulsion systems. LM-1 didn't include the landing legs and used aluminum plates in place of the glass windows; a precautionary measure after one of the windows on LM-5 shattered in a pressurization test. The last Saturn IB flight (until Skylab) was Apollo 7, the first crewed mission of the Apollo program and the first orbital test flight of the Block II CSM. The S-IVB on this flight included a docking target to allow the crew to practice the transposition and docking maneuver meant to be used in future missions. This flight also saw the last use of the hinged SLA panels after one petal failed to maintain the right angle after opening. On subsequent flights these panels were modified to be ejected following CSM separation. Up next I have four more Saturn V missions, starting with Apollo 4 and 6. These were the first two launches of the Saturn V. Apollo 4 is famous for being the virtually perfect first launch of the Saturn V. On the other hand, Apollo 6 encountered so much trouble during its ascent that the fact that it even made it into orbit is nothing short of a miracle. Both of these flights carried their own Block I CSM, each modified slightly to represent features and upgrades that were being implemented on the Block IIs. As a stand-in for the Lunar Module these flights also carried Lunar Module Test Articles, or LTAs. These were launch masses designed to represent the general size, weight, shape, and dynamic properties of the real LM during a launch. The final two missions I have to share today are Apollo 15 and 16. They were the first two J-type Apollo missions, characterized by their greatly expanded mission duration and scope, and greater focus on lunar science. In addition to their LRVs and ALSEPs each mission carried a unique scientific payload for use on the Moon. On Apollo 15 I've included the Lunar Laser Ranging Retroreflector (LRRR) and on Apollo 16 I've added its Far UV Camera (FUVC). The CSMs on these missions included a scientific instrument module, or SIM bay, installed on the service module. As their name suggests they held an array of scientific instruments as well as cameras to allow for detailed observation of the Moon from orbit. Included on these particular missions were a pair of boom-mounted spectrometers and small deployable subsatellites that would be released into lunar orbit. More info, screenshots, and downloads have been added to the main post. (P.S. I'm still collecting some screenshots and info for some of the later missions but please bear with me as they'll be filled out soon enough. In the meantime, thank you for your patience and thanks for reading!)
  5. These replicas are a lot of fun to make, I'm just glad you guys could get a kick out of them as well. And thank you! Thanks! It uses lots of tiny parts, and most importantly tiny flags. There are a few flags placed at the front of the cart that act as a handle for the kerbals to push around. They're made invisible using a custom transparent flag texture.
  6. Added more Apollo missions, this time featuring Apollo 12 and 14. The two (successful) H-type missions. Apollo 12's LM-6 Intrepid (left) and Apollo 14's LM-8 Antares (right) These were the missions planned directly after Apollo 11, distinguished by their precision landings and increased mission scope. In terms of Lunar Modules they were very similar to Eagle but the ascent stages featured the finalized beige and black panel scheme. The descent stage of Intrepid featured less black paint on Quad 1 whereas Antares' looked mostly gold from the front. They also carried some of the first full examples of the Apollo Lunar Scientific Experiments Package (ALSEP), along with a plutonium-fueled RTG. Apollo 12 was the first H-mission, and the first pinpoint landing of Apollo, famously touching down just a stone's throw from the Surveyor 3 probe. It was the first time a crew had rendezvoused with a previously launched space probe, and the only instance of it occurring on another planetary body. Of course all of this means a true recreation of Apollo 12 requires a Surveyor probe, and a crater small enough to pose them in. Recreating the probe itself was a lot of fun, though trying to get the landers close enough to pose for screenshots took copious amounts if infinite fuel and quicksaving. I wound up leapfrogging the landers into a bunch of locations trying to find a small crater to stage this screenshot. Well worth it, in the end. Apollo 14 was the last H-mission, which brought space veteran Alan Shepard back to the forefront of space exploration. The crew were tasked with a grand traverse to sample Cone crater, accompanied by the newly-designed Modular Equipment Transporter. It was basically a small towable handcart which was supposed to help carry the astronaut's equipment on their journey. Recreating this small piece of equipment turned out to be a fun little novelty. It uses transparent flags to allow your kerbals to pull it along. I wound up towing it a few hundred meters away from the LM trying to recreate some scenes from Apollo 14, made for quite the experience. Really makes you feel like Alan Shepard! More info, screenshots, and downloads have been added to the main post.
  7. you joke but I was gonna add a "stir the oxygen tanks" button If I ever get around to Apollo 13. Also with the flags I think it would be a problem only if you already had flags with the exact same name in the folder. Seems unlikely but if it does become a problem you could always rename them.
  8. More Lunar Modules, cause why not. The neat thing about making a craft entirely out of flags is that you can basically repaint the entire thing on the fly. Especially useful when you're obsessed with recreating the LM and its ever-changing exterior. Anyways, here's today's offering: LM-3 Spider and LM-4 Snoopy. Spider (left) and Snoopy (right) These LMs bear many visual distinctions which set them apart from later productions. Most notable are the Ascent Stages which were mostly clad in silvery aluminum skin panels. These panels were replaced with lighter chromic acid anodized panels starting with LM-5, giving the Ascent Stage its final beige-ish look. The Descent Stages also lacked RCS plume deflectors (also introduced on LM-5), instead the outer layers were painted with varying amounts of black Pyromark paint for thermal protection. LM-3 featured a unique semicircular paint job on the front two faces whereas LM-4 showed a much more aggressive application, with nearly the entire stage being painted black. While they carried much of the necessary equipment and instrumentation their construction made them too heavy to carry out a safe lunar landing. As Grumman worked out techniques to lighten the lander these prototypes were utilized for orbital test flights in the months prior to Apollo 11. Spider flew on Apollo 9 and was tested in LEO, demonstrating the functionality of equipment and maneuvers to be used during the landing. Snoopy was brought to the Moon on Apollo 10 for a full mission dress rehearsal, testing every component and procedure just short of landing. More info, screenshots, and downloads have been added to the main post.
  9. The Apollo Program You know it, we all love it: the legendary space program that put man on the Moon. At the time it was considered to be one of the most ambitious projects ever undertaken by either side during the Space Race. To this day the accomplishment of the Apollo program still stands as one of mankind's greatest achievements. Below are a collection of stock+DLC replicas I've built to represent the various rockets, spacecraft, and mission profiles that comprised the Apollo program—from its first test launches in 1961 to the very last flight of Apollo hardware in 1975. Currently this page features all of the Saturn I, Saturn IB, and Saturn V flights minus Apollo 13, Skylab, and ASTP. If I have the time I'd also like to include the Little Joe II and LLRV missions, but we'll just have to see how things pan out. In the meantime, check out the spoilers below! They contain a bit of info about the launch history of the Apollo program, utilizing screenshots of every rocket and mission I've built so far. Downloads and flight instructions for each individual craft are featured further down the page.

Well you can't have an LM without a CSM and S-IVB, and if you have those you might as well build the entire rest of the Saturn V, right? And while you're at it, why not slap on an LRV and try to do one of those J-missions? That'd be pretty cool. Anyways, after months of trial, error, explosions, and lazing around I finally managed to put together a Saturn V that didn't explode by, would you believe, adding more struts. After the first successful test flight I managed to find the motivation to complete the design, and it took shape pretty quickly after that. I was also gonna put together a video but at this point it's pretty clear that it'll take a bit longer than usual to create. I don't wanna sit on the craft files while I make the video though so I'm posting them here just to get them out there. In the meantime, stay tuned, and thanks for reading!
  10. No mods, but it does require both DLCs and a bunch of custom flag textures. When it's done I'll upload it to KerbalX along with the required flag textures. I'll also make a post about it here on the spacecraft exchange which'll link back to KerbalX. https://kerbalx.com/tehmattguy
  11. The Eagle has landed! And by that I mean that I've pretty much completed my replica of the Lunar Module Eagle. New legs, new engines, lower part count, extra faceting on the sides, and I've managed to shave off 0.5t from the ascent stage. The main purpose of all of this is to make it easier to reconfigure the LM for a full J-Type mission. These were the mission profiles of Apollo 15, 16, and 17, involving more extensive study of the Moon from the surface and from orbit. A scientific instrument module (SIM) bay was installed in the service module for orbital operations while the LM was fitted with extra equipment to support extended stays on the lunar surface. The LM also carried a Lunar Roving Vehicle in its descent stage, vastly expanding the range and scope of manned lunar surface exploration. Below are some screenshots of the progress I've made in trying to replicate a J-mission. CSM-114 America This command module flew on Apollo 17, the last Apollo mission to fly to the Moon. In addition to the SIM bay it also carried an additional set of antennas as a part of the ALSE experiment. LM-12 Challenger Apollo 17's Lunar Module. As with the rest of the J-missions, this LM carried a Lunar Roving Vehicle, folded up and tucked neatly into the side of the descent stage. LRV unfolding Fully deployed Attaching the rest of the equipment is the tricky part, since I figure that docking ports would be too large at this scale, and EVA construction would be ridiculous with so many parts to attach. The solution I came up with is to use a set of latches to secure pre-constructed assemblies to the rover. Each latch is made of flag parts using a transparent texture so not to ruin the aesthetic of the rover. The rover drives into the assembly before engaging its latches to grab and secure it. The assembly is then decoupled from the lander, and remains attached to the rover. Attaching the LRV equipment pallet. Moon buggy fully constructed and ready to rove. With this done it shouldn't be too long till I get the full Saturn V up and running. Hopefully.
  12. I think so, at least partially. Going through the patch notes I did see this line: "Fix trajectory changes during rotation caused by MinRBMass being too high" Looking at the Physics.cfg shows that they've reduced the partRBMassMin from 0.03 to 0.002. So it seems like the new minimum part mass is 0.002t rather than 0.03t. I tried weighing some of the previously affected parts and they do appear to be at the correct weight again. However there a few parts listed under 0.002t, namely cubic octagonal struts, navigation light mk1s, lightstrip mk1s, and some flag parts. I was guessing they'd still affected since they're under the new minimum. I'm currently trying to test these parts together with robotic parts and I feel like I'm still running into some mass oddities. Edit: Updated the main topic with more info
  13. Oh yeah, I had been testing my stages individually to an extent but not with placeholders. I'd originally wanted to test fly my S-II using a simplified S-IC but I guess I got too caught up in the idea of all-up testing. But yeah, using placeholder stages definitely seems like a good idea going forward. And thank you!
  14. Waiting on a certain bug to be fixed before continuing on my Lunar Module... In the meantime I started putting together some stages for a full Saturn V build. S-IC, featuring custom F-1 engines inspired by @Yukon0009 's designs. S-II with aft interstage and more custom J-2s. Both stages installed with the S-IVB and CSM. The S-IVB holds ~17 tons of ore in place of the LM to save on partcount/framerate during testing. Here the Saturn V is looking pretty much complete aside from some surface details which will be added later. Currently the build is sitting at over 2600 parts. Liftoff! The rocket takes several minutes to load onto the launchpad, making testing an incredibly slow process. To make things worse the rocket wants to explode during every phase of flight. It even took a few launch attempts to get it to stop exploding while throttling up the F-1s. This picture represents the furthest progress I've made, as it currently explodes when attempting a gravity turn. This is gonna take a while...
  15. Thanks! Also, the craft file for the scale has just been added to the bug tracker page.
