Ultimate Steve replied to Matuchkin's topic in KSP1 The Spacecraft Exchange
Same here! My first try at RO/RP-0 was in 0.90 and TestFlight meant I couldn't get anything to actually launch well. In my current 1.1.3 install, I don't have TestFlight and I have made huge stations, gone to the moon, and sent probes to the other planets. Also, glad to know I'm not the only one who designs KSP stuff outside of the game. EDIT: accidentally posted, this was not going to be the complete post, writing more... My first install, I had a dilemma: If I put enough fuel on my rockets to have a TWR of 1.5, the engine would burn out with half of the Delta-V still remaining. If I emptied enough of the fuel out to use all of the Delta-V, the unthrottleable engines would make rockets with TWR too high and it woul d burn up on ascent. As far as replicas go (was going to quote but now I'm on the new page) I haven't an exact replica. I prefer my own designs, it would feel too much like I'm playing someone else's campaign. Also, any gravity assist tips? I've never tried them on this scale before but when you need 20-30km/s for direct outer planet missions, gravity assists start becoming appealing. -

Random Science Facts Thread!
Ultimate Steve replied to Grand Ship Builder's topic in Science & Spaceflight
If you took away the empty space between the nucleus and the electrons, as well as between the atoms, every person on Earth would fit into a space the size of a marble. There are more possible games of Chess than the amount of atoms in the observable universe. If you shuffle a Rubik's cube by moving it randomly 20 times, there is a strong chance that nobody has gotten it scrambled that way before. Congratulations, you are the first person to do something. The russians experimented with submarine launched orbital rockets, and were somewhat successful (Shtil'). @p1t1o Also, the Nike Sprint was designed to accelerate at 100g. (Dubious, I only found one site saying this, may be wrong) When Betelgeuse goes supernova, the resulting explosion may produce a light in the sky as bright as the moon which may remain for several weeks. This is due to happen sometime within the next few thousand years. -
What are the worst mistakes you've made in KSP?
Ultimate Steve replied to UbuntuLinuxKing's topic in KSP1 Discussion
Worst mistake that nearly killed Kerbals: On my first Eve flotilla mission, I accidentally jettisoned the Gilly lander with two people still in it halfway through the Eve escape burn. Eventually, I rescued them. Dumbest mistake: Forgetting to turn on symmetry and only attaching one booster instead of three. I didn't notice until I pressed space. Most annoying mistake: Forgetting to configure the RCS in RO/RP-0. Most Kerbals killed (not reverting): returning an SSTO from a station in career mode. Landed too far down the runway and couldn't brake. I either had turned steering off or had used too big of wheels to use steering. I was going slow enough to survive if the plane went off of the runway, but then I hit a light on the end of the runway and the right wing fell off. The plane struck the ground and 6 Kerbals died. RIP. Most kerbals killed (accidental, reverting): I didn't take the time to fill the seats, but I had a 916 Kerbal mothership that I probably crashed on Minmus (and The Mun) a few times before I got it right. Funniest mistake: I flew a mission mostly from map mode to one of the moons of Kerbin once. Unfortunately, upon returning to normal view, I discovered I was orbiting the wrong moon.- 29 replies

More cinematic docking
Ultimate Steve replied to Jimmidii's topic in KSP1 Suggestions & Development Discussion
I was about to disagree with you because I always rejoice when the camera switches, but I totally agree with you, a semi-fast panning motion would greatly heighten the experience. Also, is it just me, or do half of everyone's dockings occur at sunrise? I swear, it's a conspiracy for me... -
I've made it to all of the planets with Kerbals in the game. And back to orbit. I would have gone back to Kerbin, but for Moho, Eve, and Dres, storyline obligations (this was for a mission report) kept me there. In all three cases, the capability to return to Kerbin is there. In RO/RP-0, I have landed humans on the Moon and I have (mostly) successfully landed a probe on Venus. I have also crashed into Mars...

Top secret for now, unfortunately. And, yes, it is somewhat related to The Species. Also, time is a very rare commodity right now, but besides stuff that I have to do, Chapter Twelve is, like, third on the list at this point! Wait, it's been two months?!?!?!? I didn't realize it had been that long! Sorry to keep y'all waiting.

Possible mostly renewable energy source?
Ultimate Steve replied to Ultimate Steve's topic in Science & Spaceflight
Thanks for the responses. So, basically, it might work but it wouldn't be effective, and there's easier ways to do this that work on the same general principle? Darn it I just remembered I live in the 21st century and most of the ideas have been thought of already. -
Completely ignore me if I'm wrong. This idea may be fundamentally flawed, that's why I'm bringing it up (to ask). Disclaimer: This idea is from a fictional book. I'm merely asking if it is possible. So, the Earth's core is iron, right? And Earth has magnetic poles. Suppose we found a large copper asteroid somewhere in the solar system, and we somehow put it into orbit around Earth. Would the copper asteroid circling the iron-cored Earth produce harnessable energy?

"Best" TWR Values>
Ultimate Steve replied to The Flying Kerbal's topic in KSP1 Gameplay Questions and Tutorials
As far as gravity losses go, your ideal TWR is infinite as to eliminate gravity losses. Low TWR = more gravity losses = less Delta-V available. Unfortunately, due to the laws of physics, engines require this pesky thing called matter, meaning higher TWR = more engines = more dry mass = less Delta-V. Now, these two lines intersect somewhere, there exists an ideal compromise where the delta-V wasted on more engines is equal to the Delta-V wasted by hovering in a gravity well for too long. Unfortunately this varies by rocket and there is no one true correct answer. For general rules of thumb, if your TWR is under 1.1-ish, add more engines (if its a lander you should have a TWR of 2 or more). If it is more than 3, remove engines (unless you want to completely disregard efficiency for POWER!!!). But, once you are in orbit and won't operate on a collision course with any body, the ideal TWR is 0.0000000000000...1 because the more TWR=more engines=more dry mass=less delta-V and TWR does not matter if you don't need it. At this point it becomes a tradeoff of sitting in front of a computer for four hours doing an ion burn vs. having less Delta-V. And, let's be honest, nobody likes long ion burns. At least we don't have *shudder* realistic ion engines... -
To explore, to heighten public interest, to actually do something cool. Basically what NASA tries to do. When there are no other serious competitors in the race? I'd go with the one with the better recent track record. To be fair, the rocket is literally in the hangar waiting for the pad to be ready at this point. Yes, Falcon Heavy was supposed to fly years ago, but it was pushed back for understandable reasons (constant upgrades of Falcon 9 cores). The delay the Heavy experienced may very well be non-typical. I'd say 2030's at best is a little on the pessimistic side. Yes, I believe there is very little chance that we'll land on Mars in 2024 (I probably wouldn't even bet on 2026) but SpaceX is planning on shutting down Falcon in favor of BFR after stockpiling cores for a bit. Once BFR is flying there's no reason why they can't send one to Mars straight away, and I don't see a future in which BFR is not flying until 2026. As far as point to point, it probably won't happen at the scale shown for quite some time if ever. What's the point of any orbiter probe? To study the planet.

How to make a Kraken Drive?
Ultimate Steve replied to Fireheart318's topic in KSP1 The Spacecraft Exchange
Previously you used to be able to have landing legs pushing against the craft. However, they fixed that, and now you have to have legs pushing on a craft pushing on the original craft... And now K-drives can't be reused easily because the legs glitch out and don't work after a while.- 11 replies

The picture I posted is of a Saturn V replica unless I am terribly mistaken. I did see the welcome center Saturn IB as well, though. Picture I posted: One cylinder for the most part, not many like the Saturn IB had. Picture from far away: I'm about 99% sure that isn't a Saturn IB, just saying... That one, however, is.

Update 1 - 10/22/17 So, what has happened? Well, I sent three ships to Mars. This is the Mars Communication Network, for all intents and purposes identical to the one I sent to Venus. The other two are a ten ton propulsive lander and an 0.5 ton parachute/tiny engine lander. Next up, something big: This lander, the Tranquility, was a lander sent up to Eclipse Station on a Gravity IB. It is powered by 6 radioisotope rockets (technically they are a non RO part but they are at least somewhat realistic) and designed to be reusable. It departs from the station carrying Jebediah Kerman and Stanislav Vetochkin (bet you five bucks I spelled that wrong). Now, let me back up a bit. Eclipse station was only supposed to be crewed after it was completed, but due to a bug I needed to crew one of the modules in order to be able to control it (RT did not want to work that day). However, because I had Yonder 1 docked, I could send them and have a way to get them home. Unfortunately, Yonder 1 was meant to be a test flight. However, the logic was that it was a repurposed Melody spacecraft that had flown several times already, what could go wrong? Anyways, the fact that I had crew on the station meant that I could now land people on the moon for the first time in 4-5 years or so. Again, the lander was only a test, so I was jumping the gun here, but my IRL time is valuable, so why not? Unfortunately the lander had a TWR of about 1.1 on the moon, so landing was difficult. Fortunately, I made it, although I landed at 30m/s and blew up the KIS containers (there was nothing in them anyway and I didn't have an engineer). I also had much lower fuel margin that I expected due to the low TWR, but it was a workable margin. Also, flags! Yay! I didn't have flags at the time of my first three lunar landings, so Stanislav becomes the first person to stab another celestial body (and Jeb becomes the first person to go to the Moon twice). You're probably wondering why I landed at night. There's a reason for this. You will notice that there is no science equipment on the lander. The idea was that after the test flight I'd put them in the KIS containers and deploy them once on the surface, but because my first test flight had turned into an operational flight, I decided I wanted to get some science out of it. So, I landed 2.1km from Sailor 5, the third probe to land on the Moon. Not bad for my first attempt at precision landing in RO! I then used the scientist to run the experiments and collect the data. Stanislav and Jeb set the duration record for time on the Moon at a week or two compared with the 2 minutes, few hours, and couple days of the previous 3 missions. They returned safely to Eclipse station and began processing the data in the lab. Once processed, this data will yield a few thousand science points. Then, I launched a spy satellite on a Mu V. My goal was to turn Earth into a Death Star, but due to faulty RCS (I keep making that stupid mistake) this was as close as I got. I then launched another ScanSat on a Neutron III to perform a biome scan. This too was plagued by RCS problems but was placed into a lower orbit than planned as a result. *DING* Yes! My Venus fleet is finally at Venus! This is my Venus comms network, and that is Venus, although you can't tell due to the shadow. Burning into orbit. I was 200m/s short so each of the four satellites had to complete the insertion manually. Unfortunately, due to complete lack of fuel, these four relay satellites were placed into vastly differing orbits rather than an equally spaced low orbit system that had been planned. Planetoid 10 entering Venus orbit. This is my scientific Venus lander. Now at this point I realized my comm network was pretty much useless because I overestimated my fuel capacity and the power of omnidirectional antennas. In the Earth system you can use omnis out to the Moon. However, at Venus there are no ground stations. And if omnis don't work, you need one antenna pointed at Earth and the other at the ship you want to talk to. However, all of the relay satellites only had one powerful antenna. And the lander probe had one medium strength one. The actual lander only had an omnidirectional antenna, which I thought would be enough to talk to the relays. Nope. I had forgotten to deploy the main antenna on the orbiter portion of the lander. So I had to wait until two of the relays were close enough to use the omnis and turn one of their antennas to the lander keeping the other one at Earth. After that was sorted out, I set out to land on Venus. The entry went well, however I did not have a signal connection so I could not deploy the gear, the parachute, the experiments, or even jettison the heat shield. Slightly immature comment, but it sort of felt like I was flying through farts... Wait, it survived? Cool! I mean, I was going only 30m/s, so it was a possibility. Unfortunately, I had no proof to the contractors of the first successful landing on another planet. The communication signal was cut off, and the probe was rolling downhill. However, I set up my crippled relay constellation in a way that the signal went from Earth to one relay to the elliptically orbiting lander orbiter which then traveled via Omni to the lander... Unfortunately, this connection only lasts 3 minutes per orbital pass. And, signal delay is basically 3 minutes as well, giving me about ten seconds of time when I can actually do something useful. The first thing I did was deploy the gear in order to stop the spinning, then I did science. On the next orbital pass, I transmitted the science. Yay, mission success! Almost! The Venus comm network was supposed to be a framework for future landers and it was completely broken... I'll need to send a second one (but I'm basically broke at this point so I'll have to wait a bit). Also, more bad news. I sent the exact same system to Mars. *FACEPALM* Back at Eclipse Station, I sent Bob, Jeb, and Stanislav home because they'd been on the station for several months already. Entry went flawlessly, the test flight of Yonder being successful. Now the docking port was free... This is probably the second to last Gravity III ever to launch. It carries module six of Eclipse Station, the docking module. It got to the station correctly but I forgot to take screenshots... Anyways, for a "map" of Eclipse Station... On the bottom, we have the Hadfield Utility Module, named after Chris Hadfield (awesome guy) and designed to hold electric charge, life support, fuel, and be able to reboost/move the station if necessary (in retrospect I really should have put the station in a polar orbit). Above that is the Numa habitation module (because I was listening to that Numa Numa Yay song at the time) designed to provide power and living accommodations. Above that is the Earthrise Cupola Module, which is a node and observatory platform. On the right is the Modulin Science Module, which is a science lab, designated airlock, and life support container (with around 5 man-years of supplies). On the left is the Sergeant Utility Module, which has solar panels (not deployed in the picture, that's just a tug), more living space, a KIS container, and a tank of fuel for Tranquility. The solar panels on the module are part of the space tug which has since been de-orbited. On the very top is Yonder 1 which is not there anymore and has been replaced by the North Star docking module. Sticking up from the center node I will place a command stem which will also carry cool lights. What color do y'all think would look nice? -Steve.

Welcome to my Realism Overhaul/Realistic Progression Zero mission report! This is not like my other ones, this one isn't a story, it's just me trying to space... To make a long story short, I started playing RO/RP-0 about a year ago an a 1.1.3 installation, barely got to orbit, and got bored with it. A few months ago, I picked it back up and haven't been able to put it down since. I chronicled my misadventures in the "What did you do in KSP today" thread, but after a while I thought it would be better if it had its own thread. So now I have to go and sum up 19 years of history in a short-ish introduction... Off we go! Intro: Launch Vehicles: Future plans: As far as the near term goes, I'm going to finish Eclipse station and do a few more manned moon landings. In the medium term, I'm going to do a test launch of Gravity V (200-300t to LEO) and begin building a small outpost on the moon. Long term, my goals are to build a NERVA mothership and send people to orbit Venus and walk on Mars by 1980. Updates will be in posts. I did a lot this week, and I was going to write it tonight but the OP took really long so I may not get to writing it until tomorrow. Thank you for your time, enjoy my failures (and sometimes successes)!
