  1. @Mulbin Very nice work Think you have beaten my Ancient Launcher designs in every way. regards
  2. 1) World of Tanks 2) KSP 3) Minecraft
  3. This game is in developement and will be for some time to come. I started wit 0.15 about a year ago and had 8 or so updates until now - and every time started with a fresh installation. The big thing behind KSP is "know-how". When you know how things work, they can be done again very quick. But you need the experience of a few hundred launches, landings, mishaps etc. to overcome this learing-by-doing. In my oppinion it makes no sense to wait for an update, because all wat you cen learn now you can start trough with the new update immediately on a higer level. New parts as also on the horizon, therefore even existing spacecraft designs probably will be not more usefull because thy get less efficent maybe.
  4. I tend to place yours on No1. - except the battery packs....if you have Nuke and enough solar panels for full power, what are they good for ?
  5. Hello My entry for the „Long Distance Probe“ named "maro-technoir DSM" (Deep Space Micro) probe has 567kg 5.429m/s Delta-V all four Sensors four fixed and four expanding solar panels one 88-88-type and two 16-type communotrons two battery packs xenon tank ion engine Main failsafe feature are the fixed solar arrays angled in a way to ensure power by sunlight from any direction – even one forgets to drive out the expanding panels initially the probe will keep working as long as in sunlite or when it comes back into it. Depending on sun direction one can run 40-50% sustained power.
  6. Bug Report: At launch starting at ~5000m KSP is on stop-and-go - it runs just 0,6-0,7sec. normal and then stand still, and then again 0,6-7sec normal and still and so on....until i stage, then KSP runs well again.
  7. LongMarch 2E - Optus B2 The first launcher of Chinese origin in my „ancient launchers“ project is the Long March 2E (aka „CZ-2E“). Used seven times from1990 to 1995, was five times successfull and accounted for two failures one of which is accounted for the worst launch catastrophe of the newer space history – the rocket fell on a village close to the XichangSatellite Launch Centre killing an unknown number of residents. The Long March 2E forms also the basis for the Long March 2F still in use to lanuch the manned missions of the Chinese space program (therefore cant be added to the „ancient launchers“). The technology of the Long March 2E has a military backgrund as it uses dinitrogen tetroxide as oyidizer and UDMH as fuel like the Russian Proton rocket. My KSP clone is a little bit more powerfull then the real world rocket and can put roughly 4t into a Kerbostationary transfer orbit istead of the original 3,5t/GTO performance. I chose it because it is a good example to show off how commercia lcomsats are delivered into stationary orbits this days.

The first burn emediately after upper stage separation should lift your periapsis well above 70km to avoid reentry. You can lift further but closely look at your apoapsis not passing 2.868.750m – otherwhise you have to coorect performing a retrograde burn. The last burn in your sequence you can perform to exactly place the satellite over a certain point above Kerbins aequator.

  10. scary, scary..... and now the question.....should KSP include "part failures" once in a finished version....probably as part of an "expert career mode" ?
  11. ProtonD-1e - Lunochod, 1970-1971 - First remote controlled vehicle landet on another celestrial body Launcher:http://en.wikipedia.org/wiki/Proton_(rocket) Payload:http://en.wikipedia.org/wiki/Lunokhod_1 Desctription: My first Proton-Variant used six LV-T30 in the first stage and had te tendency to be a bit weak. To overcome this i reworked the Proton and now use six Skipper, now its on the strong side. But istvery easy now to still add a x200-8 tank to the first an second stageto even improve the performance, and therfore the launcher is easy toupgrade to be able to reach targets beyond Mun and Minmus. Lander engine is also much stronger – and you need only a fraction ofthrust for the Mun landing. The Lunochod itself has now a more original „bathtube“ design and has two Nukes on board for endless power. A ramp seems still not possible, therefore i used my side-by-side descent stage design with horicontal attached decouplers, engines, tanks – that works easy and flawless. Instructions activate ASAS deactivate RCS tanks on the rover (2x)..they look out on top of the body a bit stage for engine activation rev to 100% stage for liftoff throttle down at 1000m and reduce thrust further until 10.000m – target speed at 10.000m is about 200m/s (as ever...) at 10.000m turn to a 90° heading and 70° upwards trajectory rev to 100% prior to burnout 1st stage activate RCS stage after burnout 1st will activate 2nd correct heading to 90° and 45° upwards trajectory once passing 50.000m start your orbit turn stage after burnout wait for apoapsis then stage again and complete orbit with 3rd stage manage your trans-mun-injection should use most if not all fuel of your 3rd go into a 25~30km circularize orbit with 4th stage there should be enough fuel to change inclination 30° and more make your initial braking with 4th and use as much as you can.You should be vertical at ~10.000m latest. Reduce vertical speed below 10.000m to less then 50m/s. Wait for burnout or stop engines at 7.500m and stage. Increase thrust of landing stage carfully – a lot overpowered at mun gravity. touchdown speed should be less then 3m/s, stop engines 1-2m above ground. Once stabile on the ground stage to eject landing stage activate rover sensors, antenna, light, solar panel as required - and activate RCS tanks again - in case you flip over you can use the RCS to get the rover back on wheels A verystrong proton clone lifts off stage... stageagain transmun.... andstage laststage on the way orbitinsertion managinginclination to reach the right landing area alreadyvertical andstage...used up full and took out as much descent energy as possible landingstage in action time toquit engines on theMun ok –tahts not the way the russians had chose...but it works rollin,lollin, rollin....
  12. All ships are "stock", so you do not need any plugin to fly. Anyway i recommend the Kerbal Engineer Redux: http://kerbalspaceprogram.com/0-18-1-ke...er-redux-v0-5/ Protractor: http://kerbalspaceprogram.com/protractor-for-ksp-0-18/ they are very helpfull and of course you can add auto pilot if you wish. i do not use it any longer, but in the "early days" i used a lot partly just to get an idea how it works. but the ships-file are stock-totaly free of any part or plugin thats not in the actual v0.20.2 package

  14. They are all done with v0.20.1 and v0.20.2. Dont understand die incompatibility issue and cant test either, because i do not have the Steam-Version. I check constantly but with alle the updates and fixtures running ist hard to keep on track. I will try to find out whats going on but hopefully the game will some day be finished and the incompability issues finaly solved.
  15. Zenit - Fobos-Grunt, November 9th, 2011 to (August 2014), sadly a mishap Launcher:Zenit-2SB:http://en.wikipedia.org/wiki/Zenit-2M Upperstage Fregat: http://en.wikipedia.org/wiki/Fregat Payload:http://en.wikipedia.org/wiki/Fobos-Grunt Piggyback:http://en.wikipedia.org/wiki/Yinghuo-1 OnNovember 9th,2011 russia launched the Fobos-Grunt space probe intend to collect aupto 200g sample of Fobos (one of the Mars moons) soil and bring it back to earth in August 2014. After reaching orbit around earth the probe suffered from a computer failure/programming error and never left the orbit instead stayed malfunctioning and it fell back to Earth in an uncontrolled re-entry on January 15th, 2012. This is KSPs-stock part rehearsal mission to Ike, Dunas moon…..hopefully you have more luck then the russians. Instructions Alot of stages and a lot of Delta-V here in…all together ~10.700m/s. The sample return stage alone has 1800m/s, able to lift from Ike, orbitit, changing to a high orbit around Duna and then to transfer to Kerbin. Onthe ramp Deactivate the four Stratos-V tanks on the transfer stage of Fobos-Grunt Activate ASAS stage for engine ignition Rev to 100% stage for lift off reduce thrust to minimize acceleration at 1.000m and reduce thrust further down to 2/3 up to 10.000m target speed at 10.000m is ~200m/s turn to a 90° heading trajectory 70-80° upwards. Rev up to 100% thrust Prior to burnout 1st stage activate RCS Stage twice to separate 1st stage and start engines 2nd stage. correct heading of 2nd stage back to 90° heading trajectory 70-80° upwards and deactivate RCS Once passing 50.000m start to flat out for an orbit around Kerbin After burnout stage to separate 2nd stage Set throttle to 0% Stage to activate Fregat upper stage engine Wait for apoapsis and complete orbit Plan your trans-duna-injection (TDI) shot The Fregat itself has two stages and has the ability for multiple restarts. After the first 900m/s are burned you can jettison the external tank and then you have an aditional 590m/s until burnout. To use ist best find the last tank in a row (there are two) and mark it to visualize its burnout. You can jettison the external tank at full thrust. After TDI is done stage to jettison the Fregat Move out solar panels of Fobos-Grunt Stage to activate the space probes engine A typical low energy Duna transfer takes about 100 days, Optimize your trayecory several times during the transfer – activate Stratos-V tanks and use RCS - and try to acchieve a “direct hit†trayectory to Duna. @Duna – Instructions Imediately after reaching the sphere of influence of Duna correct your trajectory for a high eliptical orbit around the poles – the target orbit should be a 3 day orbit around Duna (around 80km x 15Mm). This uses about ~450m/s Move out solar panels of your Yinghou-1 piggyback, activate sensors and light and stage to release the Yinghou-1 once reaching the 80km x 15Mm orbit. (probe activation is programmed as custom â€Â9†and releasing the prob is custom “0†Move out landing feet of Fobos-Grunt Correct your orbit for a close Ike flyby ~ 20km periapsis. Depending on Ikes position this can cost mor or less fuel – I used about ~400m/s. (Reccomendation) This maneuver is the least tim critical in the Duna orbit and you can spend all your RCS fuel for this task in order to save fuel for the final brake at Ike. Brake into a low orbit around Ike. This uses about ~400m/s. Plan your landing at Ike, chose the sunny side (!) Move in solar panels of Fobos-Grunt (security reasons in case of landing mishap) Use the rest of the fuel in the transfer stage for the first part of the landing brake Jettison transfer stage after burnout and stage for activating engines of lander Land at Ike (I got it on the ground with a slow descent profile and had still 327m/s fuel left, so ist not critical if you spend the fuel of the transfer stage wise) Activate lander, solar panels, antenna, sensors – and deactivate lander engines (programmed as custom “5â€Â) Samplereturn flight Basicinstructions Check if all four engines of the lander stage are deactivated – if not DEACTIVATE (Important!) Set throttle to 100% Activate ASAS Stage for liftoff You need some 500m/s for a low Ike orbit Then you swich to a high orbit around duna – costs you ~100m/s+ more Circularize that high orbit – another ~50m/s more And then you have some 1200m/s left and you will ned about 730m/s for the flight back to Kerbin Aim for a ~30km periapsis for a atmospheric brake/re-entry Activate chute ist the last staging event onthe ramp 2ndstage in action 2ndstage burned out Duna-transferplan...100 days mark the tank to visualize the burnout of the last external tank – once emptyyou can stage to jettison to achieve a higher deltaV staging the external tank of Fregat stating the last Fregat part Fobos-Grunt during transfer direct hit trajectory direct hit is not good – planing flyby into a high Duna orbit howit should look like releasing the Yinghou-1 piggyback managing the transfer from high Duna orbit to Ike flyby Ike here I come transfer stage used up and staged on the finals oh yeah..what a nice panorama Yinghou-1orbiting Duna....and Fobos Grunt landed on Ike from a low Ike orbit to a high Duna orbit for just ~150m/s byby Duna and Ike back to Kerbin trajectory back at Kerbin final kerbin re-entry planing samples nearly at home...
  16. Apollo LLRV (Lunar Landing Research Vehicle) SimulatorforMoonlandings,research and crew training -Link:http://en.wikipedia.org/wiki/LLRV Instructions Learn to land on the Mun like Neil Armstrong..... :-) You will find out thats not easy...because of the reduced reaction time of the jet engine and you experience the effets of using RCS close to the ground changing your descent rate and the required changes to the engine power resulting. If you are able to land this constantly, then you can land A LOT.... On the pad Extend the ladder of LLRV Make an EVA and climb the LLRV Enter LLRV seat IMPORTANT (!) Mark the remote guidance unit (below air intake) and press “control from here†- otherwise your gimbal will show you wrong indications. retract the ladder Press T (ASAS) Press R (RCS) stage to activate Engines rev to 100% stage to liftoff ...for god's sake, improve your landing skills !!! if something happens... SPACE will activate the ejection seat and the last staging event will activate the chute. eject, eject, eject....
  17. SaturnV / Apollo 11 to Apollo 17 Most powerfull launch vehicle ever buildt; first manned landing on the Moon; only manned program so far landing on another celestrial body Launcher:http://en.wikipedia.org/wiki/Saturn_V Payload:http://en.wikipedia.org/wiki/Apollo_Command/Service_Module ; Programe:http://en.wikipedia.org/wiki/Apollo_program Missions:http://en.wikipedia.org/wiki/Apollo_11; http://en.wikipedia.org/wiki/Apollo_Lunar_Module ; http://en.wikipedia.org/wiki/Lunar_Roving_Vehicle http://en.wikipedia.org/wiki/Apollo_17 Launchinstructions: Launch is not critical, ship moves straight (except at staging between 1stand 2ndstage – RCS recommended) and there is 500m/s+ more DeltaV available then required to reach the Mun. Transposition,Docking and Extraction instructions: Because the Lunar Module(LM) is located below the Command Service Module(CSM) head-to-tail it is required for the CSM to separate from the S-IVB, travel a short distance, turn 180 degrees and then dock with and extract the LM. The separator could be problematic in this sequence – it will remain on the LM docking port after separation. The solution is simple but you have to be precise. After separation(staging event) activate RCS and move a little bit forward then stop your movement. Then you start a 180° turn with the RCS within this movement you can push the separator away with the nose of the LM and dock. Landing instructions: Thereis enough fuel to make a relative slow descent landing. Burn retrograde above 20.000m until you quit your horizontal movement. I would recommend ~100m/s descent rate at 10.000m and ~50m/s at 5.000m and then you can further decrease you descent rate using RCS also. Theonly difference between the Apollo 11 and 17 files is the Lunar Rover and slightly more fuel in the landing stage of the Lunar Module. I would recommend you try Apollo 11 first as the Apollo 17 is harder toland because of the Rovers of center weight. Rover instructions (apollo 17 file): Separating the rover is a additional staging event. Rover will fall of LM. You can then turn the rover on its wheels using the buildt in RCS. Batteries on rover are good for some 3-5km and are supported by a small solar panel – you need sunlight for charging(!) or you can chose and add an Nuke Mun liftoff instructions: Deactivate the landing stage engine manually. Set throttle to 100%, activate ASAS and RCS and stage for lift off. Keep vertical until you pass 50m/s then you can slowly start to turn to the required heading for a CSM rendezvous. Staging Activate ASAS on the pad 1)Activate Engine SI-C Booster - Set to 100% thrust 2)Release Clamps - Full thrust up to 1250m, then you can gradualydecrease thrust to about three quarters until you reach 10.000m Thenincrease thrust to 100% an turn to a 90° heading and 70-80° upwardstrajectory burnoutfirst stage – this should happen at 12.000m+ . 3) ActivateRCS and stage away SI-C Booster 4) Stage to activate Engine S-II Booster ( Stages away Launch Emergency System) - Aim for anapoapsis about 150.000-200.000m. 5)Stageaway SII Booster after burnout - Set throttle to 0% (!) 6)Stage to activate S-IVB Booster - You can set now a maneuver nodeto help creating an orbit (you will have some minutes untilapoapsis) - Fire S-IVB Booster when close to apoapsis -Wait until orbit achieved, then stop engine - Set maneuver nodefor the trans-lunar-injection (TLI) - Wait for the node and fireengine again apropriate for TLI 7) Stage to separate ApolloCommand Service Module (CSM) from the third stage - Activate RCS -turn 180 degree - dock with the Lunar Module (LM) - (theseparator could be problematic in this sequence read instructionsabove) 8) Stage away S-IVB Booster -move CSM/LM-combo away from the S-IVB using RCS 9) EVA -moove two Kerbals from the CM to the LM 10) stage to activateCSM Engine - Wait for mun periasis and circle your orbit about50km - The more exact the orbit the better, this will help whenyoure LM comes back - Deactivate CSM Engine(!) 11) Stage todecouple LM - Lower you landing feet - Activate landing lightsif you wish - Set maneuver nodes for landing 12)stage to activate descent engine - Land the LM - Deactivatelanding stage engine(!) important 12a)(Apollo 17 file) stage to release rover 13)LM Starting sequence - Activate ASAS -activate RCS -CHECK your LM descent engine must be DEACTIVATED !!! -set Engine to 100% 14)stage to activate LM ascent engine and separate from landing stage -Burn straight up full power until 50m/s - Set throttle to 0% -Set maneuver node for apropriate orbit for a renedevouz with theCSM - Fire engines again to complete orbit - Rendevouz anddocking with the LM - deactivate LM ascent engine (!!!) 15)EVA - moove two Kerbals from the LM to the CM - activate CMengine(!!) - Set maneuver node for the trans-kerbin-injection(TKI) - Wait for the node and fire engine again apropriate for TKI 16)Set flightpath to reentry Kerbin athmosphere 17)stage Decouple CM - reentry 18)(St 0) Activate chute Saturn V on the pad SI-C Booster running staging SI-C Booster @ 12.000-13.000m S-II Booster running S-II Booster close to burnout staging S-II Booster ignitinon S-IVB booster - completing orbit and TLI Transposition,Docking and Extraction EVA - moving two kerbonauts in lander can leaving Kerbins SOI Orbit insertion separating LM from CSM LM gear down LM braking burn LM at the finals LM touchdown staging away rover turn rover with RCS On the move....

  18. I want to remember - Gemini 7: 13 days, 18 hours - Soyuz 9: 17days, 16 hours Therefore 10 is probably to less. But its also a question what equipment they have on board beside of foodstuff, water, oxygen and so on. For EVAs they need a pressure suit, probably they have a rack with experiments on board or goods to transport to a space station. The weight and space margins are rather complex, but for a simplified rule - 10 days is probably the right number.
  19. I made some progress right now - even made tests with payloads up to 4t - and where able to orbit it...after a while. Until now i wasnt able to achieve a glider landing - as the minimum descent rate is 40m/s - and ist not very maneuverable in any way - you cant make big turns during liftoff and orbiting and also not during landing. Therefore i stopped the developement progress and waiting for the rigth idea.... "Mulbin" is exactly right - at liftoff it is managing of the balance - i made that with RCS (a lot of) - and the balance changes over time - depending on the payload weigth it starts to roll back over the pitch axis and the engines we have are not able to control that - the solids have no TVC at all (while the real Space Shuttle Solids had TVC !) - therefore i use no solids at al but simulating the solid boosters with mainsails - and the LV-T45 (for the shuttle) has probably enough power - but definately to less TVC - the original Space shuttle SSMEs had a freedom of 10.5° on two axis while the LV-T45 has only 1° - you cant control the balance chanings with that less freedom.... And on the end - SSMEs are in fact the zenith of rocket engine development.....with a vacuum ISP some 25% more than the LV-T45.....with that long burn time in vacuum until you reach orbit - that makes also big difference. This comes out at....waiting for an KSP update that brings uns new stock parts...able to fullfill that task.
  20. thanks...like the original one. they had even to less power to add a launch-escape-tower - and the capsule was small as well. From all the Mecury-Gemini-Apollo astronauts i admire Frank Borman and James Lovell most for living allmost 14 days in this telephone cabin..amazing .....and Gordo Cooper for managing to save landing Mercury-Atlas 9with so many systems gone... (practically a wreck).... On Wednesday 15. May its 50 years anniversary of Gordos first and Mercurys last flight !!!
  21. Atlas-Centaur(AC-34) - Mariner 10, Nov3, 1973 – Mar 24, 1975 first spacecraft to use the gravitational slingshot effect to reach another planet: http://en.wikipedia.org/wiki/Gravitational_slingshot first spacecraft to visit Mercury first NASA mission to visit multiple planets Launcher:http://en.wikipedia.org/wiki/Atlas-Centaur; http://en.wikipedia.org/wiki/SM-65_Atlas Upperstage: http://en.wikipedia.org/wiki/Centaur_(rocket_stage) Payload:http://en.wikipedia.org/wiki/Mariner_10 Instuctions: Asi wrote in the original (lost) posting – this is a mission with acomplex trajectory. Once the trans-eve-injection burn and first correction is done and you stage away the Centaur, you have 850m/s(4min) of fuel left to manage a Eve flyby and three Moho flybys. The trick is to make a very „late“ shot to Eve. You have about 500-1000ms/ more DeltaV in the Centaur then the most economic Mohoshot will cost you...no problem with fuel here. Therefore you can reach a periapsis around Kerbol star much lower then the Moho orbit. But if you are to fast at Eve agrav shot will not work that well because of the high speed pass resulting. For the optimum time to launch look at the first picture. dectivate Batteries on the probe (2x) Activate ASAS with „T“ (option) activate light on the pad „U“ (was a night start) stage for activating engines rev to 100% stage for liftoff throttle down 5% at 2500m and a another 5% down a little later – not more then 10-15% (upper stage is heavy) at10000m rev up to 100% and turn to heading 90° and 80° upwards trajectory at 600m/s press „1“ to stage away booster engines at 40000-45000m 45° upwards trajectory at burnout stage away Atlas and igite Centaur circularise orbit with Centaur then stopp engine manage your trans-eve-injection (TEI) shot as close as possible to Eve (Note: Centaur batteries will last for a few orbits (probably 5) + time to leave Kerbin SOI (keep an eye on) after your initial TEI correct your trajectory to Eve for a direct hit (you have a lot of RCS for that tiny corrections) activate Batteries on the probe (2x) prior to stage away Centaur (check if thy are full!!) stage away Centaur and activate Mariner 10 probe with „2“ (now you are on solar power) mid way to Eve add a few m/s speed prograde to arrive „early“ - you have to pass Eve close in front for the gravitational slingshot effect we need whene you arrive within Eve's SOI manage your gravitational slingshot - passing Eve your resulting orbit should cross Mohos orbit twice – with aperiapsis lower then Mohos orbit and an apoapsis higher then Mohos orbit. Now its time to manage your fuel in order for passing Moho three times close. You had 850m/s out of Kerbin, the mid course boost should cost you a few m/s and the Eve pass should be ~50m/s (without large correction). What is left you can split three times – each part (~200m/s+) is your budget for one correction to reach Moho. Probably within the Eve gravshot you can find a cheap sollution to Moho (i found one with 31,8m/s for pasinge Eve and reach Moho within the first Kerbol orbit) optimumtime to launch lift off at night staging booster engines staging Atlas away trans-eve-injection done making final corrections with RCS staging away Centaur stage and activating Mariner 10 probe direct hit trajectory to Eve Luckyi am....31,8m/s for the pass of Eve and reaching Moho...saving a lotof fuel in my overall budget flybyEve niceto have a heatshield flybynumber one at Moho manageagain trajectory Flybynumer two at Moho manageagain trajectory flybyNumber three at Moho
  22. 8K78M„Molnya-M“- 3MV „Zond/Venera“, 1964-1972 The USSR „3MVplanetary probe“ where common designs for Mars and Venus missions and lifted by „Molnya-M“ rockets, another variant of the sucessfull and well known R-7/Semyorka. AlltoughZond 1 and 2 made flybys at Venus and Mars at 1964, communication where lost prior to flyby and the missions – intend to flyby with the „bus“ and land a probe - where unsuccesfull. Zond 3 made a successfull Moon flyby in 1965. Vernera 2 to Venera 8 used almost the same general design with improvements implemented each time. They are among the most succesfull USSR probes and the USSR is by now still the only nation who successfully landed spacecrafts on Venus. Venera 7 survived the immense pressure and heat on Venus surface(470°Celsius/~855°Farenheit , 90 atmospheres/9.5 MPa) for 23 minutes and Venera 8 for 50 minutes and 11 seconds. first manmade object to impact another planet's surface (Venera 3) first sucessfull lander on another planet (Venus), first broadcast from another planet's surface (23 min) (Venera 7) first successfull Venus lander (Venera 7) first spacecraft to measure the atmosphere of another planet (Venera 4) Launcher:8K87M „Molnya-M“: http://en.wikipedia.org/wiki/Molniya_(rocket) Payload„3MVplanetary probe “: http://space.skyrocket.de/doc_sdat/venera-3mv-4.htm http://en.wikipedia.org/wiki/Venera_4 http://en.wikipedia.org/wiki/3MV_planetary_probe http://en.wikipedia.org/wiki/Zond_program http://en.wikipedia.org/wiki/3MV_planetary_probe Programmes: http://en.wikipedia.org/wiki/Zond_program http://en.wikipedia.org/wiki/Venera_program Instructions WhileZond 1 and 2 where intend to flyby Venus(1) and Mars(2) they should expose a landing capsule..that never happened, but is a nice idea and you can try that. The Venera lander altough the same general design worked slightl ydifferent. Instead of expose the probe and flyby, the bus stayed with the probe during athmospheric entry and cooled the probe as long aspossible prior to separation. Tip: Plenty of DeltaV. You can go for an early approach and using the resulting eliptical orbit around the Kerbol star to manage another planetary flyby.... activate ASAS on the pad with „T“ stage for engine activation and ground power off (note: you are on batts now until probe activation!!) rev engines to 100% stage for liftoff rev down to limit acceleration between 1000m and 10000m once 10000m passed rev up to 100%, turn toe heading 90° and 70° upwards trajectory stage away boosters after burnout start circularize orbit when passing 50000m stage away booster after burnout stage to activate upper stage and circularize orbit manage your transfer shot stage away upper stage after transplanetary injection and early correction activate probe bus with „5“ make flight path correction as apropriate for a direct hit or close flyby a) Option Zond-style: expose landing probe and bus flyby after reaching the SOI (sphere of influence) of your target planet set your periapsis as low as apropriate to ensure a capture of the landing probe max. 10 hours prior to periapsis stage for landing probe separation after staging switch from landing probe to bus rise your periapsis apropriate for a close flyby switch back to landing probe at atmospheric entry activate landing probe with „6“ stage for parachute activation below 10000m b)Option Venera-style: impact bus and landing probe after reaching the SOI (sphere of influence) set your periapsis as low as apropriate to ensure a capture of the landing probe at atmospheric entry activate landing probe with „6“ after deceleration below 1000m/s stage for landing probe separation stage for parachute activation below 10000m NOTE: landing probe will only work for some hours....this thing works only on batts!! padat night groundpower off liftoff „Molnya-M“with „3MV“planetary probe boostersaway onthe way to orbit stagingthe Molnya away Orbitcompletition and transplanetary shoot with the upper stage directhit separationfrom upper stage spacecraftactivation midcourse correction withinSOI manage a direct hit separationfrom landing probe Landingat Eve night whata speed....thats survivable ! sunrise
  23. Atlas LV-3 – Agena ATV, 1965-1966 Unmanned spacecraft used during theGemini programm to practice space rendevouz and docking techniques.Agena ATVs where also used to lift docket Gemini capsules into higherorbits. Launcher:http://en.wikipedia.org/wiki/SM-65_Atlas Payload:http://en.wikipedia.org/wiki/Agena_target_vehicle Instructions Very easy...lots of Delta V. Use RCSfor trajectory changings (!). Orignial Agenas had batteries fordurations of several days but no solar arrays – this one is fitedwith a PB-NUK and will live forever.....deorbit with the lastfuel/RCS. activate ASAS on the pad with „T“ stage for engine activation rev to 100% stage for liftoff reduce acceleration between 1000m and 1000m at 10000m rev engines to 100% and turn to heading 20° and 45° upwards trajectory at 800m/s press „1“ to stage away booster engines and change heading to 29° flat your trajectory and manage thrust for a apropriate low Kerbin orbit stage away booster after burnout circularize orbit with Agena ATV press „1“ for Agena ATV antenna liftoff i improoved the shape of my Atlasfurther.... the Agena in space
  24. Titan IIGLV – Gemini, 1965-1966 second human US spaceflight program first US EVA first rendevouz maneuvers first docking maneuver (with GATV) first long endurance flights (13d, 18h) several developement and equiment tests required for Apollo program Launcher:https://en.wikipedia.org/wiki/Titan_II_GLV Payload:http://historicspacecraft.com/Gemini_Capsules.html Project:https://en.wikipedia.org/wiki/Project_Gemini Missions: https://en.wikipedia.org/wiki/Gemini_3 https://en.wikipedia.org/wiki/Gemini_4 https://en.wikipedia.org/wiki/Gemini_5 https://en.wikipedia.org/wiki/Gemini_7 https://en.wikipedia.org/wiki/Gemini_6A https://en.wikipedia.org/wiki/Gemini_8 https://en.wikipedia.org/wiki/Gemini_9A https://en.wikipedia.org/wiki/Gemini_10 https://en.wikipedia.org/wiki/Gemini_11 https://en.wikipedia.org/wiki/Gemini_12 Instructions Until0.19 KSP stock engines do not offer a engine strong enough for the Titan booster – Mainsail is to large and to strong and the LV-T30 is to weak. Therefore i added in total 24 x 24-77 engines to the first stage to keep the two-engines optic and reach a the trust level required. Also KSP offers no two-crew capsule right now – therefore i took the Lander-can and put an adapter on top – works and looks still like a capsule. The Gemini had no launch escape tower because of weight restrictions.Instead crew was placed on ejection seats – what we also not havein KSP right now. There is a emergency sequence programmed that stopps the engines, and uses the retro system to seperate the capsule. Activate ASAS with „T“ stage for engine activation rev to 100% stage for liftoff (do not wait to long for liftoff otherwise tower will be damaged at liftoff) as acceleration is quite slow (24-77 are not that effective) wait for throttle down until ~2500m once reaching 10000m rev to 100%, turn to heading 20° and trajectory 70° upwards burnout first stage should happen 19-20000m and 460~470m/s – stage twice to separate first stage and ignite second stage – turn to heading 29° and trajectory 70° upwards start flatten your trajectory once passing 50000m there is not much fuel margin – but enough to reach a 80 x 90km orbit with the second stage if you operate economic – keep you apoapsis below 90km and manage your engine thrust to circularize your orbit. stage away second stage after burnout use RCS for orbital maneuvers Landingsequence orient prograde stage away equipment section (RCS fuel tanks) orient retrograde stage to activate retro boosters stage away retrograde section between 10000m and 15000m stage away docking node below 300m/s activate prachuteturn to heading 20° and trajectory 70° upwards
