River-run Air-race Challenge
Scarecrow replied to selfish_meme's topic in KSP1 Challenges & Mission ideas
After numerous attempts, many of which failed for breaching 400m or simply crashed, I finally managed a complete run and landed back at the starting point island. There is a little wobble at the end of the landing run, but nothing broke or fell off. Engines are staged at the 1:00 minute mark on the mission clock, and everything comes to a stop on the island at 9:19, so I am claiming an elapsed time for the mission of 8:18. This is in a stock aircraft using keyboard control. I think I could knock a few seconds off if I started slowing down for my landing a bit sooner, and didn't overshoot the island by a fair bit while still trying to slow down, but I am quite happy with this run. The replay is at 5x times speed so as not to bore everyone with an 8 min+ video, but I can upload a replay at slower speed if required for verification. -
River-run Air-race Challenge
Scarecrow replied to selfish_meme's topic in KSP1 Challenges & Mission ideas
Nice challenge. I've had a go, but with the really imprecise controls of using a keyboard it's difficult to be smooth at the speeds required to get a good time. Just a nano second too long on the W or S key can result in a major change in altitude, or loss of speed if you are in a tight turn. My time was around 9 minutes, but I don't think I could do better than that without an analogue control. -
Here's my entry. Basically put 2 relay satellites in my shuttle which I then put in to orbit around Mun, right on the edge of the SOI. The satellites were then deployed and orbits adjusted to match that of Mun, with one preceding it and the other trailing. Mission images

Do these satellites need to be part of a single launch or can they be launched separately?

Terriers to orbit Part Two (Poodle time)
Scarecrow replied to DAL59's topic in KSP1 Challenges & Mission ideas
I started off trying the spaceplane approach, but quickly realised that because the Terrier is so bad at sea level, it actually takes ages to get to an altitude where they start being really useful, by which time most of the fuel had gone. My final solution was a rocket that used quite a few Terriers initially, just to get that gain in altitude, but progressively jettisoning them to save weight and improve the rate of acceleration. -
Plane keeps veering
Scarecrow replied to TheAngryHulk's topic in KSP1 Gameplay Questions and Tutorials
Definitely something going on with your centre of lift indicator. In the top down view it looks to be a little off centre, and for most aircraft to fly successfully the CoL should be slightly behind the CoG. Having said that, I can't see anything on your craft that would have the CoL situated so far forward. -
I've never been particularly interested in visiting America, but seeing that LEM has made me wonder about visiting one of the space museums to actually see the Saturn for real. They had a J2 engine in the Science Museum, which was quite impressive, but we all know that the F1 engines were substantially bigger. The people who actually experienced that thing taking off must have found it to be a unique experience, never to be forgotten. The size is one thing, which we can appreciate to some extent by seeing the museum exhibits, but I guess the sound generated at lift off is something that will be forever consigned to the past.

I've just got back from a visit to the science museum in London, where they currently have an exhibit about space. Part of that exhibit is a replica of the Apollo LEM and I have to say I was surprised at how big it was. I guess my impression of how big it would be was influenced by models of the Saturn V rocket, where the LEM is quite small by comparison. Having now seen a full size replica of the LEM, I'm finding it difficult now to imagine just how big the Saturn V actually was.

KASA Space Station entry I assume it's OK to launch this station in several parts, which are assembled in orbit. My effort was launched in 5 parts; the station core, a habitation module, a comms and power supply module and 2 science modules. The life boat pod was sent up last, with a crew for the station, now that we could get them home in the event of an emergency. Unfortunately it was soon realised that someone at KASA had misread the requirements, and the initial orbit for the station was set at 350km. Fortunately a small engine was included as part of the core module, and it was a fairly simple process to reduce the orbit to meet the actual requirements. Oh the joys of being a rocket scientist.

So go do them, just don't expect any rewards, recognition or badges from the guys who set these missions, as they have laid out a specific set of requirements, which you won't meet by doing your own thing.

@michal.don Thanks for the missions, and the badges. I will be calling a halt there, as I have never been a fan of tracking asteroids and always have them switched off, so Mission STS-9 is a non-starter. The Mun and planet missions look interesting, but I am not sure my skill levels are up to completing them. Maybe at some point I may try the Mun ones and see how I get on.
-
@michal.don A quick question before I carry on with my missions. I am currently in the middle of mission STS 5-8, can you build me. On the last flight I thought I would land on the Island runway just to vary things. This decision was made while still in orbit, and not because I had overshot KSC, but then I wondered if this would count for the Commander badge? As the island runway is a lot smaller than the KSC runway, in theory it is more difficult, but if it doesn't count then I have a game save at the point where I was about to do my de-orbit burn so I can redo my landing to land at KSC.
-
@michal.don Yep, that one came in direct from a 600km orbit so a bit excessive on the G-meter but I was quite pleased that nothing exploded on the way down. A quick question. As I had to do a re-run of mission STS-3, and the missions should be run in order, does that mean you would like me to now do STS-4 again?

Single Launch Mun space station
Scarecrow replied to kolan4ik88's topic in KSP1 Challenges & Mission ideas
Here you go. Mun station weighing in at 30.02t launched to a 50km orbit around Mun. Station in the VAB The complete vehicle Gets off the pad fine This is the bit that will be transferring to Mun In orbit ready to go, just waiting for the crew to arrive -
STS-2b accomplished. I initially attempted this mission with the Shuttle that I used to launch the fuel pod, knowing that it was a tight fit in the cargo hold. Unfortunately after including a docking port in the hold to re-capture the pod, it turned out that there wan't enough clearance and it wouldn't fit. As a result I fitted an extra cargo hold module to lengthen the hold, but didn't do any flight trials before attempting the mission again. That was a mistake as it turned out the centre of lift was way aft, which gave very little elevator authority once the pod was on board and we were back in the atmosphere. Made it very difficult to slow down, and was only just about enough to prevent ploughing a new furrow down the runway with the nose wheel. Anyway, mission pictures. Night launch this time Jeb reckons it doesn't look the same when it's not bathed in sunlight. Orbital data says we will be close enough on the next orbit to complete our rendezvous Solar panels retracted, as it definitely won't fit with those still sticking out Everything is looking good at this point And we're docked Jeb was blaming brake failure, but I'm not so sure. Despite actually touching down on the runway, as you can see I wasn't able to get it stopped before running off the end. If this isn't close enough to count as landing back at KSC, I can do the mission again, but I would have to Hyperedit the fuel pod back in to orbit. I have already tweaked the aerodynamics to make the craft more flyable, so it shouldn't prove too difficult if I have to do it again. I will hold off doing any more missions until I get a ruling on this one.
