Returning a science rover from the Mun to Kerbin?

Combat air patrol mission? Best, -Slashy

Maybe it was just me, but I had to switch to an alternate live feed because the video quality was so awful.

W00t!

LoSBoL, I was also on the Val hype train. Still am, in fact. I like her ongoing rivalry with Jeb. Agreed. I think any kerbal should become an orange suit once they gain enough experience. But as for adding more kerbals at the outset of the game... Not so much. Best, -Slashy

Hotaru, I actually want to see female kerbals out on the production floor merely to liven the place up a bit. But then again... I've also always wanted my VAB and SPH to be a "Ming the Merciless"- style evil lair, where my starved minions are forced to toil in dark, brutal conditions at the mercy of their lash- wielding overlords. Every time I look down there and see happy workers in their clean workspace and 401k retirement plans, it makes me kind of sad. After all, it's not like there's salary and operating expenses dialed in the budget in career mode, and you've got to make 'em work somehow... I see no reason why I shouldn't have that so I enjoy the game more Diff'rent strokes (no pun intended)... Best, -Slashy

Okay, so that gives us the info we need to compute your fuel requirement... provided you don't go using those Poodles you just mentioned. We compute it all backwards, from the end of the mission to the beginning. For the trip home, your ship is 62 tonnes dry. 1,700 m/sec DV. We compute the fuel as above. 1700/(9.81*800)= 0.2166. e(.2166)= 1.242 wet to dry ratio. 0.242*62 tonnes = 15 tonnes of fuel. For the trip out there, you have your 62t empty ship, the aforementioned 15t of fuel to get home, and the 18t LAAM. 95t. 1700 m/sec DV still translates to the same wet to dry ratio; 1.242. .242*95t= 23t of fuel to get you to Duna. So all told, 38t of fuel. 1t is 200 units, so 7,600 units. Best, -Slashy

[Snip] Ironically, I'd prefer to have more female kerbals around simply for the added variety. Moreover, my agency is 100% egalitarian and merit- based. If you are capable of getting yourself haplessly stranded in orbit, you have a spot on my roster. I literally have no interest in (or even any idea of) the gender makeup of my roster; all are equally qualified. But having said that... I don't want KSP promoting any ideology, even one that I agree with. I certainly don't want it promoting *this* ideology, which I am opposed to. [Snip] I object to any change in this game merely to promote some agenda, particularly this one. I need a better reason than that. Best, -Slashy

Gus Grizzom, Now we're cookin' with gas. Do you plan on aerobraking at either end? Best, -Slashy

Federal refunds are taxed in my State. And yeah, I *did* pay taxes on that money the year prior. Refunds are not "free money", they're just money that you had already earned (and paid taxes on) being returned to you because they withheld too much. Best, -Slashy

Gus Grizzom, What's the mass of the LAAM? What's the dry mass of the ship without the LAAM? Best, -Slashy

Guz Grizzom, You need exactly the same DV to get home as you did to get out there. Are you planning on aerobraking at Kerbin? If not, then that's another 1,700 m/sec DV that we need to account for. The process is exactly the same as described above, but the fuel requirement will be wildly different. You must first define the mission of a stage. What's it's payload? Minimum acceleration? total DV budget? You can design the stage only after you have answered these questions. Best, -Slashy

Triop, Basically, what it's saying is that I must place my sat in a specific spot along an orbit, not just merely anywhere in the orbit. And it doesn't provide a reference for me to rendezvous with. It provides a spot, but that spot is on the ground. And it doesn't state exactly where that spot is, it just provides a nav marker. It's up to me to figure out how to get the sat in a kerbosynchronous orbit exactly overhead that little patch of ground. Luckily, I hosted a challenge last year to do just this sort of thing, so I already know how to do it. This is a common contract requirement in the real world, and I've never seen it come up in KSP before. I'm really happy to see it. Best, -Slashy

I picked up an awesome contract in career today; a contract type that I didn't know even existed before: Place a sat in KSO above a specific spot on Kerbin! Thank you, Squad!! The contract doesn't specify the longitude of the ground spot, it just places a waypoint on the surface. But I already know how to figure it out. This one is gonna be fun -Slashy

So what we do is this: Assuming we are following precisely your mission plan, we need to get from low Kerbin orbit to low Duna orbit. I don't know how you plan on getting back, but the calculation process is identical... According to the map , DV to get to LDO is 1,700 m/sec. You didn't say you're aerobraking, so I'm assuming you're not. We divide that by g0; 9.81 m/sec2 = 173.35 We then divide that by our LV-N's specific impulse of 800 sec, which equals 0.2167. We then raise e to that power. e(0.2167) = 1.242 Our wet to dry mass ratio is 1.242. That is; our ship plus fuel mass is 1.242 times our ship mass without fuel. Converting that to a less- confusing value, (1.242-1) = .242; Our fuel is 24.2% the mass of the ship when dry. Your ship's dry mass is 70 tonnes. That means you need 24.2%* 70 tonnes of fuel, which is 17 tonnes. 200 units of fuel is 1 tonne, so you need 200*17=3,400 units of fuel. As a sanity check: Your ship weighs (70+17)= 87 tonnes when loaded, and 70 tonnes when dry. 87/70=1.243 wet to dry ratio. ln(1.243)= .217. * 9.81= 2.133 *800sec= 1,706 m/sec DV. Again... this is only enough fuel to get you from LKO to LDO without aerobraking. You will arrive in LDO out of gas. If you need to do more (or less) than this, then figure out exactly what your DV budget is, then apply the same process to find your fuel quantity. HTHs, -Slashy

Let's *not* be good feminists. I don't appreciate it when people try to force their "isms" on me in my entertainment. If I want more female kerbonauts, I know how to acquire them.

Welding. Weld all of this.

Outstanding! I'm glad it's working out for you. Best, -Slashy

You see, the time warp is just a jump to the left... -Slashy

All evil characters. Evil characters are fun. Yes, Obi-Wan is an evil character -Slashy

CMcCF, The orbital period of a 600 km orbit is almost 5 hours. A difference in SMA of 100 m equates to a little over 3 seconds per orbit; about .0007° error per orbit. It'd take about 1200 days for a sat to get 1° out of position with that discrepancy; approximately 3 years. It probably won't be visibly noticeable until 10 years or so. HTHs, -Slashy

But.. we know how Han got the Falcon. He won it from Lando in a sabacc game. Sorry, spoiler alert... -Slashy

CMcCF, Old news, no longer applies. Best, -Slashy

Thank you, international press! You like me! You really like me!
