Your objective: Build the smallest rocket possible that can get into orbit. There are 2 categories, each with 2 sub-categories. I will judge each rocket in 2 separate ways, cost and mass. Each one will have its own leader board. The rules are simple. No cheating with Hyperedit, debug menu, ect. The rocket must be completely stock. No mods that alter physics and no clipping parts to exploit physics. The rocket can be manned or unmanned, each will have their own leader board. Make sure to post pictures showing your rocket in flight and showing it's mass and cost. ALSO: The rocket must be a rocket, not a cross between a rocket and a plane. It must take off from the launch pad ,and have other rocket qualities. https://imgur.com/a/swbkZaD This is my entry LOWEST MASS ROCKETS Unmanned: 1. Pds314- 0.855 tonnes 2. Pds314- 1.091 tonnes 3. mystified- 1.491 tonnes 4. Johnster_Space_Program- 3.420 tonnes 5. DRAG0Nmon- 4.460 tonnes Manned: 1. Aetharan- 1.990 tonnes 2. Aetharan- 2.053 tonnes 3. Aetharan- 2.085 tonnes 4. Aetharan-2.159 tonnes 5. Ironbars- 2.175 tonnes LOWEST COST ROCKETS Unmanned: 1. Pds314- 640 kerbucks 2. Pds314- 2110 kerbucks 3. mystified- 4580 kerbucks 4. Johnster_Space_Program- 5250 kerbucks 5. DRAG0Nmon- 7,154 kerbucks Manned: 1. TheFlyingKerman- 2603 kerbucks 2. Aetharan- 3907 kerbucks 3. farmerben- 3982 kerbucks 4. Aetharan- 4276 kerbucks 5. Ironbars- 4423 kerbucks Notes- zolotiyeruki, if you can find some screenshots of that old craft, I will gladly accept it! Pds314 maintains the top 2 spots for lightest and cheapest unmanned crafts. TheFlyingKerman holds the cheapest manned rocket. Artharan has almost stolen every spot for the lightest manned rocket, taking 1, 2, 3, and 4! Will he be able to take 5? Keep up the amazing work everyone!

As one can tell, Matt Lowne did a video showcasing a Laythe SSTO with 4025 m/s dV in LKO. So my challenge will be, can you do better? Could you make the most out of as little dV as possible? Here are the rules: ---------------------------------------------------------------------------------------------------------------------------------------------- 1) No dirty cheating alpacas (no debug menu) 2) You must have either a video or a full album of the mission 3) KER must be installed 4) No mods (besides KER) 5) You must show the Resource Tab always if you make a video 6) You must bring at least 10 passengers with 2 pilots to Laythe and back 7) Finally, you have to have clear knowledge of gravity assists ---------------------------------------------------------------------------------------------------------------------------------------------- Leaderboard: 1st place: @herbal space program, 3390 m/s (Yay, you get your first badge) 2nd place: @Matt Lowne, 4025 m/s 3rd place: @Firemetal, 6250 m/s ---------------------------------------------------------------------------------------------------------------------------------------------- So build away, intrepid builders. May the Best SSTO win! ---------------------------------------------------------------------------------------------------------------------------------------------- Oh yeah, anyone who at least beat Matt's score gets a badge (WIP).

So the challenge rules are simple: -The rocket has to have a periapsis and appoapsis above 70km -No clipping -One kerbal onboard -The kerbal has to return safely to kerbin -EAS external command seats are allowed -No KAL-1000 overclock exploit -No cheats -No mods -DLCs are allowed Good luck!

When career mode starts, all you have is the parachute, the basic command module, and the RT-5 SRB. Your launch pad also has a 30-part, 18-tonne limit. However, you have full access to staging, and explosive decoupling is always a possibility. You can also set the individual fuel and thrust levels of each RT-5 during assembly. With a few tricks, it might be possible to squeeze quite a bit of dV out of an appropriately-designed vehicle within those limitations. Who wants to give it a go? EDIT: At Ultimate Steve's suggestion, I'm making two leaderboards: one for maximum altitude, one for maximum velocity. SPEEDSTERS: 1. Ultimate Steve (1.891 km/s) 2. 3. SOARERS: 1. Ultimate Steve (338.14 km) 2. 3.
