OK, can we still do a free-return trajectory?

 

what is that (sorry still a newb to ksp haven't even been to the Mün yet)

yeah that's fine and really quite cool I think that is NASA's plan for EM-1

This

This trajectory was used by the Apollo missions in case of an engine malfunction on the way to the moon. This would provide a free return to Earth without needing an engine. Apollo 13 used this trajectory that you see here.

EM-1 unmanned?

Don't you mean EFT-1?  EM-1 is going to be unmanned but EFT-1 was also unmanned.

oh okay cool. And no EFT-1 was manned. EM-1 will be unmanned.

The re-entry angle was very steep (~45 degree angle) which caused Orion to go over 15 Gees.

I am looking for a rocket that is easily modifiable and can lift a heavy payload. And well frankly your SLS looks extremely powerful and i love the Orion missions

Well let's see how powerful mine really is. Using some quick math, my SLS has around 9,676 kn of thrust, which is around 2,175,251 pounds of force (The real SLS will have almost 8.4 million pounds of thrust). Using this formula  {\text{TWR}}={\frac {F_{T}}{m\cdot g}}>1  we can find the TWR. This rocket weighs about 600 tons, so we can plug in 9,676 for F_{T}  and 600 for m. Multiply m by surface gravity (g) which is 9.81 m/s squared. So multiply 600 by 9.81 and you get 5,886. Divide 5,886 by 9,676 and you will get a TWR of 1.64, so my SLS is pretty powerful, considering it's entire first stage has 12 orange tanks clipped together.

Anyways, enough of boring math, here is the link.

Who needs math, just add more boosters.
