That should answer your question. Although not mentioned, you do not get the points for return.

Sorry, I didn't take those screenshots with making a challenge later in mind. I just put that in. Very soon I will do a mission for this challenge.

Thanks, adding these changes now.

thanks for the advice, making the changes now. Sorry for any inaccuracies, this is my first challenge.

Welcome to the Heavyweight Challenge! In this challenge the goal is to get the largest weight you can from Kerbin, to another celestial body and back in one piece. Rules Your mass is the mass you return to Kerbin's surface. The whole of the mass you return to Kerbin must get in an encounter or orbit with your celestial body. The whole of the mass you return to Kerbin must land on the celestial body if you decide to land. If only part of what returns landed on the celestial body, then you can do the points calculations for each part of the ship separately. No aerobraking except on Kerbin return You cannot simply send just a Kerbal with the RCS pack to the surface of Minmus and back. You do not get the points for getting in orbit round Kerbin. Points accumulate (so you get 1710 points if you land on the mun, 860 + 210 + 640). Your craft must make it back to Kerbin. If you feel any of the points are unrepresentative of the difficulty of the task, please tell me in a post and I will edit it. Point System Your points are determined by the Delta-V you used on the mission. Refer to this map: http://forum.kerbalspaceprogram.com/threads/25360-Delta-V-map To get your score follow the line you took and add up the numbers along the way. Read the information on the post for more info. To get your final score you multiply all the points you got from above by the weight of your craft safely returned to Kerbin in one piece. My Attempt I was unable to get good screenshots of my craft so I will be doing the mission again and will post my entry soon. Leaderboard: 1st : 2nd : 3rd : 4th : 5th :

Hello, I was finding the Delta-V of a section of a craft I made. Please can you confirm my calculation as this is my first delta-v calculation: (rockomax poodle engine, my weights are correct for the craft) DeltaV = (9.81*Isp)*(in(Mfuelled/Mempty)) DeltaV = (9.81*390)*(in(20.97 / 12.97)) DeltaV = 3825.9 * (in(1.61680802)) DeltaV = 3825.9 * 0.48045384751060720536776041863122 DeltaV = 1838.16838 Thanks for all responses

How would I calculate the amount of delta v an engine can provide with 100 units (an flt-100 tank) of fuel? Thanks

Thanks, and thanks to everyone else too. How would i accept this as the answer and label the thread as answered?

Hello, I was reading about the engines in the game and noticed that they all, (obviously) use 0.9 liquidfuel and 1.1 oxidiser as their fuel ratio. And they all have different thrusts, my queries are this: Does the thrust of an engine correspond to how much acceleration it offers in m/s(^2) ? How would I be able to calculate the speed of fuel depletion of an engine at full thrust ? What are ISPs of an engine? Thanks for all answers

Hey, I just learnt the math of basic orbiting and I wanted to ask how much delta-v would be needed to take 1 unit of mass (kg or tonne) to a height of 100km above Kerbin's surface. I am unable to calculate the effects of gravity and drag on my craft. If I can find that out then I can calculate how much delta-v is needed to put a ship into oribt around kerbin. If you could post the figure in m/s needed for 1kg or 1000kg to rise straight up to 100km above ground. Thanks

Hey, don't stress, after about a month on the demo i was able to get to the mun, i had no idea how to get back though. Do what hobbsyoyo said and also remember, when you launch back up and get into orbit around the mun, when you are going to burn for kerbin transfer all you do is burn prograde when you are in between the mun and kerbin, saves a lot of fuel from burning later. Just remember "the earlier you burn, the less you burn".

Aboard my space station, with only highly explosive fuel for company... My jeb has gone through some great things, he went solo to the mun and back, and solo to minmus and back. Now he is spending his "vacation" doing research aboard the KSS Redemption. I'm planning to send some real supplies up along with a friend soon, but for now he is eating oxidiser.

My best moment would be when i first used aerobraking. After having (in sandbox mode) never brought a flight back from having left kerbin, it was rather pleasing for me to see my mun lander just glide in there. As I am considering a career in astrophysics i found it fascinating

Cool missiles there. Really keeping a high standard of detail in all your ships!

sure, Ill put it on the main post right now EDIT: Link is at the bottom of my main post
