Munar mission – White Rock 1

by hobbitalastair

I managed to complete a Mun mission, on the second try, about a week ago.

I flew my White Rock 1 unmanned rocket to the Mun.

Ignition in 5... 4...

The first step in any mission is getting the rocket into orbit. With White Rock 1, this is fairly simple; although the rocket uses asparagus staging, only 1 stage is fully used up during the Kerbin ascent.

The world is very blue...

After orbiting, I lined up a manuever node, trying to optimise for the most efficient Mun capture. My ‘average’ Mun captures so far have been around 800m/s – which I am quite happy with as I budgeted 860m/s, according to my trusty dV chart. However, that does not include the Mun orbit maneuver, which tends to cost around 300m/s to stabilise an orbit around the Mun.

Now, how to land...

Landing was slightly more complex. On my last mission, I had stuffed up the landing by not burning soon enough – cue large explosions:

Pretty explosion

Early Mun mission gone wrong…

This time, I intended to do it ‘properly’. I got out my pen and paper, and plugged in the (approximated) numbers – 300m/s start speed, 50kn engine, Munar gravity of around 1.6m/s^2, and did my best to land. I burnt too early still – worrying, since I needed that fuel to get home. Next time, I will be more precise… hopefully not too precise 😉

Note the LV-909...

My first Mun landing!

Success! The Kerbals back home could rejoice – oh, wait a minute, it was only a probe. Boring….

After collecting my hard earned science, I headed back home. Mun take off is a breeze, and so is Kerbin intercept. There was a tense moment – I was not sure I had enough fuel to get home. I could have done a quick calculation, but it was too late anyway….

Luckily I had enough for a direct Kerbin entry.

Home sweet home...

Landing in the desert, just after sunset.

With my hard earned science, I then went out and researched some rover wheels – but that is a subject for another post.
