    [1.4.*] AFBW Revived (Joystick & controller mod)

    If you use FAR, that has all the tools you need as well. On a recent flight of 1203km I was able to use the Roll stabilizer as an autopilot in conjunction with Waypoint Manager. WM gives me a Great Circle heading to a destination. Due to the rotating planet that heading changes over the course of the flight by a tenth of a degree every minute or so depending on which way I'm flying. So just saying "hold wings level at 0 degrees roll" will drift me off course. But you can open the FAR settings for the stability controls and set the desired amount of roll/pitch/yaw you want. it's accurate to hold a roll to a hundredth of a degree (at least). So I can set it to hold 0.25° (for example) and the aircraft kept pace with the changing heading. I was hands-off the stick from after take off until the time came to approach and land, not counting the middle where I reached the objective and had to fly around manually a bit.

    I have a trim feature tweak to suggest as well, where the axis position sets the trim position. Currently moving the trim axis sets the magnitude of the trim travel. So if I want to adjust my trim a bit I have to “blip” the knob, tweaking it forward and back or back and forward just a bit to make the change. Nothing like that is part of this mod, it’s all direct control

    The Kerbal Space Agency: Enter the Goo

    Operations Summary – Week of 5/21/18 Images from the Week Gallery Progenitor and Ascension Readying to Head to Space The next launch is nearing and the Progeny Mk6 Block I rocket has finished its final inspection. It will launch from the north field where we sent up Progeny Mk2s on eastward trajectories back in 2016. Launch time remains 13:49 UTC this coming Tuesday. In addition, the parts have arrived to begin construction on the Progeny Mk6 Block II rockets set to go up in mid-June. We’ll have more concrete details like dates and times after the first Ascension Mk1 launch but we can say that no payload instruments other than the radiation sensor will be on the first launch as we’re still not sure the air brakes will be able to get it back safely from well beyond 500km apokee. Speaking of which, the Ascension Mk1 is continuing to come together nicely in the VAB, next week the 1t test weight will get its comms, data recorders, batteries and science instruments installed for the flight. We’ll also be attaching the radial parachutes to the booster for our attempt at recovering the entire rocket for study. Launch time has been set – get ready for our first orbital attempt on 6/6 @ 20:17 UTC! Succeed or fail, parts are already being made for the following Mk1 that will go up sometime in early July. Genesis Tests New Instruments This week the Deuce flew two missions, starting with a survey flight out east for a contract during which a new camera was tested. Designed to be radially attached directly to a fuselage and streamlined against the airflow this “booster cam” as it is known will serve the purpose of allowing controllers to monitor payloads deployed off the roof of the aircraft. It will also be used for Ascension rockets to allow review of footage capturing the booster rockets falling away from the Mk1 Block II design or just monitoring the fins and control surfaces of the Block I. Later in the week Jeb and Val flew another flight to test out the radially-attached mystery goo containment unit, which allows for the goo sample to be exposed directly to the atmosphere in flight. No issues were had during the mission, the unit properly opened and closed on command and remained firmly attached to the underbelly of the aircraft. The goo did not seem adversely affected by the flight up as high as 6km ASL. KerBalloon Sends Up Two Probes Also getting in on the mystery goo action was KerBalloon, which launched a probe carrying an inline goo containment unit, serving the same function as the radial instrument and allowing the sample onboard to be exposed or sealed on command. A smaller version is also available for use on future Progeny rockets. The goo came back from above the oxygen-rich layer of the atmosphere and scientists at first thought it was dead due to lack of oxygen but after a day back at sea level the goo slowly came out of some sort of stasis and seems to be healthy upon further study. Scientists are fascinated by this ability and wonder if it could even protect the goo while it is in space. The second balloon release was an actual contract mission that took the crew out in UTVs for the first time in several months. They traversed the rough Highlands west of KSC to reach their release site and sent up a high-altitude balloon carrying material studies and meteorological instruments. The payload is currently being recovered for transport back to KSC and we’ll have a full report here later today upon their return. Deep Space Network Milestones Both ATN Central and the Arekibo Radio Observatory passed a critical milestone in their development this week. The Central observatory’s 10m telescope now has all 6 of its mirror segments complete, they will be shipped over to the site for installation starting next month. The Arekibo Radio Observatory has cleared through initial data testing of the comm lines that were installed both overland and undersea, 3 months of rigorous signal transmissions have come up with no major flaws. Both observatories remain on schedule to become fully operational next year. You can learn more about them and our DSN in this article. Extremis Reconsiders Rejected Phase Two Trajectories Head over to this news release for details, but the gist is that mission planners failed to take into account large radial/normal Δv components in the initial burn from Kerbin that inflated the total mission Δv cost. So some trajectories that didn’t make the cut for Phase Two because they used >3km/s of Δv could actually require less than that if the escape burn is performed from a more optimal orbit the vessel is launched into rather than the default 200km equatorial orbit used in the initial calculations. ATN Database The weekly update for the Asteroid Tracking Network database is available here, containing 1,982 asteroids and 7 updated with new observation data. Celestial Snapshot of the Week We’ve previously featured an image from Commander Valentina taken of Vall eclipsing the sun over Laythe while both dropped shadows on Jool, but this time an opportunity was available to capture Tylo eclipsing the sun over Laythe while they both dropped some shade on Jool. Problem was this event, which occurred multiple times over the course of about 3 weeks, happened mainly during conjunction when Jool was near or behind the sun. Either that or no scopes were properly positioned to capture it. The last possible chance was seized by the Ockr Observatory and even then they barely missed it as sunrise was just minutes away.

    [1.1] AFBW v1.7-beta (Joystick & controller mod)

    sure, had a few click-thru problems in the past that would be nice to not deal with anymore
  5. Like I said, no worries I can make it work as is. Thanks though - maybe a low-priority item to add at some point
  6. next one was only 4 seconds sooner than predicted. will continue to see how the accuracy changes over time, unless @Arrowstar comes back and tells me this is all irrelevant because there's a known error margin
  7. Yup, which is why I tried SS. I tried months ago to get the stock FX small enough to look good for smaller rockets to no avail. Oh well. It just means I can't do a continuous video shot of lift-off and need to cut to a diff view and manually disable the smoke emitter in between. No biggie

    [1.4.x] Nice MKseries Body [NMB] [V2.2] [2018.5.19]

  9. it does cut out now, but still not low enough from the ground, even if I tried 0.99999 instead of 0.98. Bummer. Any other ideas? If not I'll just switch camera angles between the initial launch smoke start and the actual lift off and just disable the emitter in between
  10. doesn't matter. A separate log is made for crashes but a regular log is always created as soon as you start the game. See the bottom-most link in MOARdV's sig for locations of the log file

    [1.4.1] kOS v1.1.5.2 : kOS Scriptable Autopilot System

    it used to have a part module field that would say whether it was safe to deploy or not but recently it switched over to the stock way of changing the staging icon color, which is what I was hoping kOS was looking for when it was determining whether a chute was safe to open or not. Guess not.
  12. @sarbian or anyone that can help with some insight - I'm working on using physics particles for ground smoke and the effect is nice but I don't want the smoke after the rocket takes off. This is my config right now MODEL_MULTI_SHURIKEN_PERSIST { transformName = thrustTransform localRotation = 0,0,0 localPosition = 0,0,0 fixedScale = 0.05 name = smoke modelName = RealPlume/MP_Nazari_FX/smokelaunch particleCountLimit = 8000 speed = 8 grow = 0.0 0 grow = 1.0 1 renderMode = "Billboard" collide = true physical = true collideRatio = 0 stickiness = 0.25 sizeClamp = 5 angle = 0.0 1.0 angle = 50.0 1.0 distance = 0.0 1.0 distance = 100.0 1 logGrow { density = 1.0 20 density = 0.1 25 density = 0.0 2 } logGrowScale { density = 1.0 2 density = 0.8 2.5 density = 0.46 3 density = 0.2 3 density = 0.1 3 density = 0.0 5 } linGrow { density = 1.0 0 density = 0.46 0 density = 0.2 0 density = 0.05 5 density = 0.0 10 } emission { density = 1.0 5.0 density = 0.98 0 } energy { density = 1.0 3 density = 0.3 3 density = 0.05 0.1 density = 0.0 0.0 } size { density = 1.0 1 density = 0.8 1.2 density = 0.6 2 density = 0.2 3 density = 0.0 7 } } I thought the emission curve would take care of it but the smoke just keeps coming even after launch. Any ideas? I only spent about an hour on it and it's 1am now so probably mission something dumb. Will revisit it after some sleep...
  13. Yup, I just added the line in there myself and boom - 8000 particles (well, ~5000 since the first ones had faded out by then)

    [1.4.1] kOS v1.1.5.2 : kOS Scriptable Autopilot System

    does the code example for CHUTESAFE work with RealChute? I started doing some testing tonight but I couldn't tell if it was not meant to work or I was doing it wrong.
