Mission Hudrie


COBALT

Recommended Posts

Yesterday I conducted my first Mun landing. I used Foursh's Munitaur II spacecraft to achieve this. Once landing on the Mun I decided I didn't WANT to make the return voyage. It felt like there would be no trace of my journey if I simply headed back to Kerbin.

I had an idea. The mods I had installed were: Cart Mod, ISA MapSat, Camera Mod, and Flag Mod.

PLANNING

I decided to conduct a mission to land a rover on the Mun. It would be composed of a cart with a command module and camera on top and a height-mapping satellite tucked under bottom. I wanted to use the Munitaur again but it is used to land a "command module with fuel and an engine for landing and return to Kerbin". I wanted it to land my rover.

I did some major changes to the 'Mun orbit insertion/landing/return" stage and tested weight and I finally came up with a design that would not require changes to the first stage of the Munitaur. Not needing to make a return trip helped too :)

I was almost ready to make the journey but when I tested the lander I realised that once I disconnected the radial engines (used for Munar orbit insert/landing) my rover couldn't move as it was surrounded by the engines. I INSTANTLY came up with a solution. Once landed using the landing legs I would turn on the radial engines slightly, JUST not enough to lift off. Then when I disconnect the radial decouplers the change of mass allows for the engines to fly away from the rover in a kind of water fountain shape :cool:

THE MISSION

I was ready. I got into a low orbit of 12km, waited for Munrise and fired my engine. Once into an Mun passby I retro-burned into a Munar orbit. I lowered the Periapsis to 5km, reached the Periapsis, then retro-burned again until the orbit was broken. I lost all of my horizontal momentum then slowly descended, burning upwards occasionally to slow my fall. Once I was only about 20m above the munar surface I lowered by landing legs and slowly touched down. I had finally landed but the greatest show was yet to come. I had to separate out my rover. I performed the technique I have named the 'Jonmund maneuver';) (someones probably done it before me.) and turned my engines "slightly" on. I hit the space bar and watched them fly away and my rover had finally landed safely.
