Challenge Finesse your lunar landings.

[Max Pain]

Ok, this time I got it better :
2750.0 in a XR2 Ravenstar.



A replay is included. My way of landing is a little bit strange: I used the main engines for braking because I wanted to minimize gravitational fuel losses.

 

[dgatsoulis]

Congrats to blixel and Max Pain. We got a good score and an excellent score.


Using the main engines for the braking burn is the most efficient way to do it. Lower burn time means lower gravitational losses.

Scoreboard updated. Don't forget that you can improve on the score as many times as you want.

So close!

Finesse my lunar landings? LOL I just fire my engines and land wherever I crash.

Actually this looks pretty sweet. You can't use LOLAMFD though, that's cheating.

Excellent landing. :thumbup:
If you hadn't used the autoland AP you would have saved more fuel.

Glad you like it. As I mentioned before in this thread, autopilots are acceptable. The dV budget has been tuned so that they are difficult to use.
Besides, LOLA will make the braking burn with the hover engines, which means less power→more burntime→more gravitational losses.

It takes skill and practice get a score close to what Max Pain and blixel posted.

Scoreboard updated.

...I had to disable Avira Antivir however, for the lua script to work...

Same here...

Have to try with [ame=http://www.orbithangar.com/searchid.php?ID=3503]BaseLandAutopilot[/ame], it can brake with mains.

 

[blixel]

Definitely not a score to be proud of, but the XR5 score keeping has to start somewhere.

Edit: I gave the Deltaglider a go as well. It didn't beat your score, but I'll post it anyway just to give myself a benchmark for my next attempt.

I didn't know about topper's autopilot. I'll give it a try later today.

Thanks for the scores blixel. Scoreboard updated.

My attempt with the standard DG and a normal LOI/PDL. No autopilots.

Hey blixel could you please make a video on how to use the base sync,and the burntime mfd to land perfectly at a base on the moon.Thanks

I'm not an expert with either of those MFD's by any stretch, but I know the basics well enough to provide simple instructions. I'll see about making a video at some point, but for the time being I can sum up BaseSync with just a couple of screenshots. It is very simple to use.

Here is a basic scenario that has the Deltaglider already in orbit around the moon. It is lined up pretty well with Brighton Beach, but there's room for improvement. See if you can figure out how to use BaseSync MFD (using the above screenshots as a reference) to bring the Distance closer to 0. Note that a Distance of 0.00 is nearly impossible to hold, so don't waste fuel by trying to keep the distance that low. As long as the Distance is within a few hundred meters, you are perfectly fine.

When you load BaseSyncMFD, make sure that:

1. You set the target to Brighton Beach.
2. You press ENC until the Encounter Mode is Closest Passage.
3. You press E/D until the Equator/Direct is set to Direct.
4. Optionally, press NUM and set the number of lines to 1. If you plan to land on the first orbit, there's no need to have all 8 lined displayed.

Very nice! I'd love to have seen a video of your braking burn and landing. My problem is when I get right there over the pad, I just can't think/respond fast enough to have a nice smooth landing. I need to use hover hold so that I can concentrate on getting the vessel centered over the pad. If I don't use hover hold, then I will end up concentrating so much on the vertical speed that I miss the landing pad.

Hello guys,this is the first time i've taken up a challenge so i dont know how lua console works,but here is my score:
http://s1350.photobucket.com/user/downloaderfan/media/Capture_zpscce5e6b0.png.html

I dont know why the first two are so low compared to the third,maybe cuz i started them both from a saved scenario in between cuz i failed the first time i did this,however the third value seems to be valid. (Which i performed completely in one go)

Sorry for the late reply, I hadn't seen the edit in your post.
Unfortunately, I didn't record that one, because it was my first attempt for that day. I wasn't expecting a good score. :lol:

I've tried a couple more times and was unable to get below 2750.
I'll change my tactic on the next try; Forget about the face forward orientation and try to land it while going "backwards".

Hi downloaderfan. Wow, impressive score.

You are right about the first two scores. The challenge is set to be flown in one session, that's why it shows such a small score if you pick it up from a save.


Scoreboard on post#1 updated.

 

[downloaderfan]

Thanks for the quick replies and posting this awesome challenge scenario.BTW pushed myself even furthur with the XR2:

dv wherever could be saved,was saved in the above attempt.(that is as per my definition)

 

[JSwift]

I tried this briefly a while ago, lost the screencap and just found it again. It wasn't that great but I haven't had time for Orbiter lately to try to improve it so I'll post it anyway. Let's call it setting the bar low - everyone should beat this :lol:

If I remember correctly, both attempts had overshoots and one had an accidental hover over the pad for way too long before I realized it. There's lots of dV to gain there.

Good challenge Dimitris. Interesting because I don't usually try to fly with 100% fuel conservation in mind and it highlighted quite a few things I had to do differently.

 

[Aztronut66]

This looks like fun. Will try this the first chance I get. Here is a landing I made at Brighton Base. Would easily have cleared the crater walls I believe.

 

[dgatsoulis]

Have fun with the challenge. Waiting to see your score.

 

[Buck Rogers]

Hi all, finally got back to Orbiter, wanted something quick & dirty and was reminded of this on the forum, which I'd actually downloaded long ago! First of all thanks a lot for the great challenge, it's always good to test your skills and is perfect for improving my landing techniques. After a couple of fails; piling onto, and landing on the BB tower?:facepalm:I had a few successes and was a little shocked to see it would appear that I made pole position! (Deltaglider) The flight wasn't perfect, there's still a few DV's to save, and it wasn't fully manual; major respect for your (dgatsoulis) flying skills that I've seen in some videos!

Semi-automated descent & landing using:
IMFD Map -don't know a more accurate PeA readout over distance
IMFD Orbit Insert -most accurate/economical circularize burn AP?(when it works?)
Hover MFD 1.1.0 -braking guidance, attitude control, linear course correction, and final touchdown.
Came screeching in just a few meters over the crater walls and let her drop as fast as I could dare!

I welcome a revenge! and look forward to future challenges (+/other). Always appreciative of the efforts from the Orbiter Community.
P.S. please just use the one top score (it's probably only one entry per person anyway, right?) even if just for the personal pride of seeing my name amongst the famous (dgatsoulis, blixel).
P.P.S. A very big, and very belated thankyou to all on the IMS thread for the extremely warm welcome I received; the antispamfirstpostdelay threw me off track and reallife distractions did the rest, hope to get a look at that soon too!

 

[Koloss]

Here is my attempt:

2,599.4 Delta V used.

-> Delta Glider IV

:tiphat:

 

[dgatsoulis]

Nice score Koloss. :thumbup:
You kept the gravitational losses at a minimum. Scoreboard updated.

 

[Koloss]

Nice, thank you!

Next up: XR-5... I'll try it this evening.
