Solution: Sunshade to cool Venus down until its atmosphere freezes, then ship the excess SO2 and CO2 to Mars.

⁠@@MrCubFan415fr that would take trillions and trillions of dollars-aswell with the fact you can’t just “ship” an atmosphere from one planet to the other.

@@AstroPlayser It was a joke, my friend.

Well um actually, 🤓 Mercury is the closest the most, while venus's orbit is the closest

Same. It was weird.

I for some reason feel attached to them like I feel bad when one dies

over a game

That's exactly how I treat the KSP career save in which I flew this mission - an alternate history timeline (that started by Apollo spacecraft NOT being retired in favor of a boondoggle Space Shuttle in the 1970s). This is what I truly love about KSP RSS/RO. I'm able to create my own fictional timeline, where dumb politicians do not change NASA's crewed plans between the Moon and Mars every couple of years. Where Boeing continues to be a competent aerospace company that ultimately develops the first reusable rocket (Ares I, predecessor of Ares II) or where Ares VI (my SLS equivalent, also developed by 'better' Boeing) is designed to actually launch hardware into deep space, instead of being a massive jobs program.

@@Lewy94999 That clarifies things immensely! I also noticed that your Ares VI uses the Pratt & Whitney Rocketdyne/Dynetics "Pyrios" booster concept proposed for Block II SLS - which each use 2 F-1-derived engines with Saturn V heritage - I always favored that idea as a (relatively) "easy" upgrade for SLS. Of course, SLS has turned-out to be a DISASTER - and THIS article proves that, yes, indeed, it CAN get worse: spacenews.com/sls-cost-growth-exceeds-threshold-for-formal-review/

@@Lewy94999 I can't but fully agree with your comment. But the Space Shuttle from an engineering standpoint was a remarkable vechicle. Unfortunately it failed on basically all its initial premises

Vassilios Pupkios same with basically anyone

actually his plan is very similar to DAR 5.0 which was the layout for a constellation mars mission

incredible.

lipo 842 worlds works too

He has spoken

Endurance space enterprises this mission takes more delta v than my Jool missions.

We all start somewhere, Rome was not built in one day.

*i tried to send a orbital probe to Duna I missed and went for a orbit higher then jool*

And that really set me back cus I can only land on mun and minmus

@@anuragkuldeep8059 your right it was built in 2

Thank you for creating CMES, it is a fantastic mod. One without which this mission just wouldn't be possible.

I made a couple like that too.

Too bad that it completely murders the fps. I deleted all robotic parts from later missions.

Finally finished watching this... and just wow. The amount of planning and designing is simply astounding. I couldn’t even pull something with tbis much detail off in regular KSP, and you did it in RSS. Incredible work

*mein Gott*

Your mod is amazing and very well made, thank you for creating it. I enjoy the MMSEV so much, it performed flawlessly on Mars. :D

Thanks!

Thanks!

Not only KSP videos, but literally half of the videos on youtube.

And half of the KSP game soundtrack...

Yea, after 300 days on Mars, those two rovers were like crew members.

@@Lewy94999 so the crew it will be back to earth ? I tough they could stay on mars forever or until die

Thanks! But I don't think I will do a Space X like Mars mission and even if I do, it won't be an exact recreation. I play my KSP career save as an alternate timeline, where a lot of things in spaceflight went differently after 1970s. And the thing is, Space X doesn't exist in my timeline (Boeing-Grumman took the role of pioneering reusable landing rockets instead). I have a candidate fictional company that might be able to do what Space X plans, but I don't promise anything. And if it ever happens, it will be much later, only after my current Mars mission program is finished (so after 2037 game time).

My Ares II has nothing to do with Falcon 9, except the paint job.

Thank you!

Nah stock ksp is still fun ngl. If it used the RSS as stock it would be boring. You wouldnt be able to see Laythes incredible views of jool. Have a fun second moon etc etc

How you described it would likely be the way to do it on a real mission. However in KSP this would actually be harder to do, since there was almost no way to precisely steer and 'dock' the 14 ton storage module onto the trailer while it swinged in every direction. My way of doing it was just navigating around the game's and robotic mod limitations. Also not having a docking port on that trailer lowered the part count a bit.

Yes. When the crew departed to Mars in late 2026, I also send four cargo landers for the second crewed mission during that same Mars transfer window. Second crewed mission departed in the second MTVN in late 2028 and flew to Mars alongside cargo landers for mission #3. So cargo always departs one transfer window before the crew. This is mainly because the ascent vehicle needs about two years to produce methane/oxygen propellant on surface of Mars.

Scorpu Would you be able to give a quick written update on what’s happening in your save? I completely understand not being able to make videos often because they do take a lot of effort, but I’m really curious to see what’s going on since you’re kind of entering that era where we don’t really know what is going to happen with space exploration. Colonizing Mars or the Moon? Going to another solar system?

​@@harrisongilbert Right now it is May 2031 in my save. Crewed Mars mission #3 departed in January 2031 in MTV Perseverance. After this, there will be three more Mars missions (they will include Phobos and Deimos landings). After those are done, I will begin construction of Mars surface base (mission #6 starts in 2037, first base elements will fly on the next, 2039 transfer window). I also plan a crewed mission to one of the Jovian moons during the 2040s. Closer to home, assembly of new LEO space station will be completed in 2032 or 2033 (previous station was deorbited in 2027 after 37 years of service). This new station is being built, maintained and resupplied by private companies, NASA (which I technically play as) is only a customer that pays for its astronaut stays on the station. Crewed flights to and from the station are also done by private companies. All this will eventually lead to full commercialization of low Earth orbit. Once LEO is fully commercialized, I plan to expand this to the Moon. Private companies will develop capabilities to fly humans to and from the Moon. This will eventually lead to setting up a surface base near the Lunar south pole and water ice mining operations. There is also a lot happening on the robotic missions side. Mercury Lander mission was launched in 2029. There is one orbiter around Venus (since 2017), one lander was sent to Venus during 2020s and there will be 3 Venus missions during 2030s (2 atmospheric probes, 1 orbiter). At the Moon, Lunar Reconnaissance Orbiter is getting old (launched in 2009), so in 2030 I launched a new orbiter. There will also be a lander that scouts a location for the future Lunar surface base. Around Mars there are 9 active orbiters, that now mostly scout the surface for human missions and support communications. Some of those orbiters are getting old and will have to be replaced during 2030s. At Jupiter, Jupiter Icy Moons Explorer mission ended in October 2030. First robotic Europa Landing took place in May 2029. There is also a spacecraft in Ganymede orbit. Next missions will be Io Volcano Observer, Callisto Orbiter and Ganymede Lander. Saturn. Cassini mission ended in 2023. One month later, Titan Saturn System Mission arrived and since then has been a lone explorer of Saturn system. Until September 2030, when Dragonfly octocopter landed on Titan. Next missions will be Enceladus Orbiter, Titan Orbiter and Enceladus Lander. Uranus and Neptune. Last spacecraft to visit those planets were two Voyager probes in late 1980s and early 1990s. Uranus Orbiter was launched in 2021 and arrived in May 2031. Neptune Orbiter was launched in 2019 and will arrive at Neptune in 2032. In early 2030, Pluto Orbiter mission was launched. It will arrive at Pluto in 2046. It carries a small lander that will land on Pluto. Uhh... This came out long. Robotic missions are just as important as crewed ones (if not more).

​@@Lewy94999 That was really interesting, thank you so much! Just out of curiosity, do you have any sort of plan for your next video? A human landing on a Jovian moon sounds really interesting, I don't think I've ever heard of a DRA-like design study for a Jovian moon landing.

@@harrisongilbert I have some ideas for next videos. Robotic Mercury Lander mission, crewed Phobos landing and commercial crewed Lunar mission. Also a bit further into the future, a robotic Pluto orbiter and crewed Jovian moon mission, but those two will be in mid 2040s.

I am just as surprised about KZfaq recommending it as you are. I could even say that... It's a surprise to be sure, but a welcome one.

Haha

When launching from Earth I was only focusing on getting into proper low Earth parking orbit and then getting a Mars encounter. Once the landers left Earth's sphere of influence, I planned out a course correction that cleaned up injection maneuver inaccuracies and brought Mars surface impact location close to the landing area (within 500km, MechJeb's landing autopilot has a landing location prediction function). Usually that first correction happened 130 to 180 days after launch. After completing first correction maneuvers, I planned out a second set of course corrections, 40 to 30 days before landers arrival on Mars. Then a third and final set of corrections, just after each lander entered Mars' SOI. For first and second set of corrections I used MechJebs Landing Prediction, for the third set I used Trajectories Mod's much more precise predictions to fine tune landers landing point to within 20km from the targeted landing site.

Thanks for the detailed answer! I don’t use a MechJeb too often and I don’t know its capabilities very well.

Practice

ShiiDox or use mechjeb

Maybe. But instead of a medicine, it shoots hydrogen at 9120 meters per second from its back.

@@Lewy94999 probably would cause just as much adrenaline too

Thanks. Rover parts are from a mod called Capsule Corp. Endeavour (Mars Base Camp). Most of the new engines I added by creating new variants in existing RO global engine configs (located in GameData\RealismOverhaul\Engine_Configs folder). So my F-1C variants are attached to F-1B global config, AJ23-242's use AJ10-190 config, MDV engines use SuperDraco config and J-2X-x use, well... J-2X config. This method saves a ton of work, because it doesn't require making new base part, RO part, RO global and plume configs for entirely new parts. But it only works for engines that are similar in size (mass can be adjusted per engine variant in global configs). For STME and MTV nuclear engine I created new parts that utilize existing engine models. STME uses RS-25 (SSME) model from SSTU mod, but I made new base part, RO part, RO global and plume configs for it. STME variants could work as attachment to SSME global config, but I wanted my STME to have several upgrade variants and I didn't want to clutter SSME config too much. Nuclear engine uses BNTR model from Chaka Monkey and it also needed all new configs.

I think the cost would be comparable. Saturn V MLV would have three stages: MS-II with 5 J-2S engines, MS-IC with 5 F-1A engines and 4 solid boosters similar to those on the Shuttle (assuming Mars payload launch configurarion, for which MS-IVB wouldn't really be needed). My Ares VI also has three stages: EDS II upper stage with 2 J-2S+ engines, Core Stage with 7 or 6 STME (SSME derived gas generator engine) engines and two boosters with 2 F-1C (modern F-1A) engines each. F-1C and J-2S+ engines are also used on a smaller Ares II rocket, so a large production rate of those engines would lower the price per single engine. As for the MEM. I decided to split Mars descent and ascent between two vehicles, because a combined descent/ascent vehicle would have launch mass of 70 to 80 tons. Ares VI payload to Mars is 65 tons. And MEM would have to be launched fully fueled, because it wouldn't have time for ISRU propellant production, if it would land crewed.

@@Lewy94999 Then that makes sense too however the development cost of Ares family rockets might make it more expensive. Saturn MLV or 5B was actually planned to use SRBs that were used on Titan III rockets. I wonder the shuttle ones are even more powerful. What about redundency? Surely a failure during descent means no way for a ascent abort, resulting in a crew death.

@@FeverDev64 Descent Vehicle has 8 landing engines, divided into two sets. One set is mounted higher and is angled slightly, so that it can perform a deorbit burn, when the heatshield is still attached to the spacecraft. The other engine set fires straight down, but can only be activated after heatshield jettison. Those engines are pressure fed and use hypergolic propellant - all for simplicity and higher reliability. Should anything fail, Descent Vehicle can land with as little as two active engines, as long as they're on the opposite sides of the craft. Also, there are 3 sets of parachutes: a primary set and two backup sets.

@@Lewy94999 Oh I see that! Did you design the mission plan yourself or was it acutally considered this way?

​@@FeverDev64 I took multiple existing mission plans and modified them to my needs. Most of the plan is from Constellation Mars mission (Nuclear Mars transfer vehicle, Orion, long duration surface stay). Uncrewed Cargo Landers are from a mission design that would be supported by Space Launch System. And split descent/ascent vehicles, with ascent element using ISRU propellant production are based on Robert Zubrin's Mars Direct plans and Andy Weir's novel 'The Martian'.

Thank you. Both drop tanks were the same lenght. It was just dumb me who firstly, didn't put the docking port exactly in the middle of those tanks and secondly, docked them rotated by 180 degrees relative to one another. I aslo didn't notice this until I reviewed the footage before making the video.

Thanks. The 70 tons for combined ascent/descent vehicle assumes no ISRU. It would have to be launched fully fueled and that would be too heavy for either the Ares IV or the MTV (I also didn't want to fiddle with Mars orbit rendezvous). Launching it half empty, bringing it to Mars with the MTV and starting ISRU after the crew has landed also wasn't an option. I have a rule which states that no one lands on Mars, unless there is a fully fueled ascent vehicle already on the surface.

@@Lewy94999 I see, that's a very sensible rule considering human lives are at stake! Thanks again for the inspiring video!
