  1. Still working on that Saturn IB! Right now I've got the CSM, S-IVB, and LES in (mostly) working order. Recently I was able to add a detail that I've always found interesting: The LES' canards. These were small deployable surfaces installed at the top of the LES. During an abort they would deploy to reorient the CM heatshield-first into the wind before tower jettison. Now for my KSP demonstration: LES firing and canard deployment. Tower jettison. Chutes deployed! And finally to test further at higher altitudes I whipped up this cursed Proton-Apo
  2. As requested by @pTrevTrevs, here's a tutorial on making stock fold-out solar panels! Specifically, this is just my own process for making a fairly compact folding mechanism while maintaining clean surface aesthetic. I should also preface this by saying that this does require using the Breaking Ground DLC. First, a small point on solar panels. Before building your mechanism I suggest pre-constructing your individual solar panel segments. For each individual panel I like to use a single small root part such as a cubic octagonal strut or a grip pad. Doing this makes it easi
  3. Back again with yet another Soyuz variant! The new update gives us better control when building fairings, so I rebuilt all the fairings on my Soyuz to achieve a smoother and more accurate fuselage shape. I was also able to make use of the new decal parts to help complete the look. Introducing Soyuz 7K-TM. This was a variant of the Soyuz 7K-T purpose-built for the Apollo-Soyuz Test Project. It carried a unique solar panel array and a new set of antennas to aid in communication with the Apollo spacecraft. It also carried an APAS-75 docking mechanism, which was a docking system co-devel
  4. Looks incredible! I love how you handled the grid flooring as well. Can't wait to see how this one turns out.
  5. Made some more progress on Salyut 4. This time I was able to add a bit more detail thanks to the power of grip pads. Here I have it flipped over to show off the markings and instrumentation on the underside. On the aft section I added a large circular marking to represent where the solar telescope should be. I also added a sort of "neck frill" to the area in front of the solar array. Docked with a Soyuz 7K-T. These were the successor to the 7K-OKS Soyuz, and featured large whip antennas in place of the solar panels. Another shot of the forward work compartment
  6. Got the Breaking Ground DLC recently, and so naturally I've been opening up completed builds and installing folding solar panels and antenna mechanisms everywhere. Soyuz 7K-OKS with DLC fold-out solar panels and antennas. Docked to Salyut 1, featuring similar upgrades. The SSVP docking mechanism has also been redone using the DLC. Once the spacecraft are mechanically locked a hydraulic piston retracts the Soyuz's docking probe, exposing the clamp-o-tron jr beneath. Another hydraulic piston pushes a clamp-o-tron jr through the drogue assembly, bringing the two clamp-o
  7. Another attempt at recreating a US launcher, this time with the Thor-Delta. This was the fourth member of the Thor family and the first to bear the "Delta" name. With this I'm hoping to start a line of replicas of the Delta rocket family and Japanese Thor-derived vehicles. First stage separation and fairing jettison. From left to right are Stage I "Thor", Stage II "Delta" and Stage III "Altair". Delta was an upgraded Able rocket stage which featured a cold gas attitude control system. After engine cutoff, it maintains its orientation while coasting to apoapsis. Altair was a small sol
  8. Did some more flight tests on the Atlas LV-3B but its been challenging getting the perfomance required to reach orbit. The main issue is the Mercury capsule, which produces a lot of drag in its current state. To help test some redesigns I took a cue from the real Mercury program and built my own "Little Joe". These were solid fuel booster rockets made to test the Mercury capsule's launch escape system and to assess its aerodynamic properties. In the meantime I've started decorating a model of the Soyuz 7K-L1, otherwise known as "Zond". This was essentially a cut down version of the 7
  9. Just a little update: I've added the 7K-OKS variant to cap off this series of first-gen Soyuz spacecraft. This version featured the SSVP docking port which allowed for internal crew transfer unlike its predecessor. It only flew twice in 1971 as a ferry to the Salyut 1 space station. During its first flight in April 1971, the crew of Soyuz 10 attempted to dock with the station but were forced to abort after a failure of the Soyuz's docking system. Another attempt was made by the crew Soyuz 11, which was ultimately successful. The crew entered Salyut 1 using the new ports, and inhabite
  10. Man, that's one slick Tomcat. Really captures the look-- I love it!
  11. Following the release of my Soyuz 7K-OK, I wanted to cap it off with the last of the first gen Soyuz: 7K-OKS. This variant used the newly-developed SSVP docking system which allowed for internal crew transfer. Painting depicting Soyuz 10. In this mission a Soyuz 7K-OKS attempted to dock with Salyut 1, both equipped with SSVP ports. This was the first attempted use of the SSVP system. SSVP drogue port (left) and probe port (right) The drogue port mainly consists of a cone made out of solar panels, while the probe port uses a communotron 16 as the probe. Behind e
  12. Soyuz This model represents the original Soyuz 11A511 carrier rocket and its payload: Soyuz 7K-OK. The 11A511 was derived from the Voskhod 11A57, upgraded to increase lifting capacity and reliability for crewed missions. It also featured the "Type 1" SAS tower, distinguishable by its dome-shaped fairing. Soyuz flew in this configuration from starting in 1966 with Kosmos-133, up until 1971 with Soyuz 11. Following missions would carry the second generation Soyuz 7K-T. They would also use the "Type 1a" SAS tower which lacked the dome. As for the spacecraft itself, the Soyuz 7K-OK repre
  13. In an attempt to diversify my replica collection I've started working on a replica of the Atlas LV-3B. It was a manned launch vehicle used by the US during Project Mercury to put the first American into orbit. A novel feature of the Atlas was its "stage-and-a-half" system. Part way through the flight the Atlas would shed its outer booster engines, leaving the central sustainer engine and verniers to continue the ascent. Getting this to work on my stock replica has been challenging as there is barely any space between the sustainer engine and booster assembly. My current solution is t
  14. Thank you! And the hinges are made of the Linear RCS Ports held in place by thermometers. For the ramp each segment is clipped slightly into the main craft so that when I decouple them they get a slight kick and are pushed out at the right speed. The heat shield on top of the Lunokhod has an oversized collision mesh, so it pushes the lid out when it's decoupled. However this also means that the lid can't close completely over the heat shield so I haven't added a mechanism to close the lid, unfortunately.
  15. Thank you! The fairings are real finicky but they get the job done.
