    I have been a member of the forums since March 2013. The date of my profile says April because I also remember The Great Forum Crash of April 2013 that swallowed up and destroyed several weeks’ worth of posts without backups (thanks, Squad!)

    Same, damn it's hard to imagine it's been 10 years.   just hard to get your head around.

    I think the steam community needs to see more activity like this. Right now the game is rating mixed with only 50 percent positive ratings which is heartbreaking. Many of us are excited about the future of Kerbal but hearing more from the devs may restore trust in the project and dev team. I would be lying if I said there has been a loss of trust out there after the launch of the game. Perhaps an address video to the community that empathizes the difficulties many are experiencing would be better received than just a bug list. 

     Seeing stuff like this really shouldn't change the Steam reviews.   Steam makes it very clear that your reviews about early access games should be about the game NOW not promises for the future.    Trust should have no effect on steam reviews if people are unhappy with the current state of the game they should give it a negative review on Steam not give it a positive cuz it might get better.

    where was YOUR first interplanetry land?

    spelling

    Lets see, very first interplanetary trip was in version .18 or .19  Took a overly tall BobCat H.O.M.E. system to Duna, attempting to land this top heavy beast on on the side of a hill somewhere around -20,-63  

    Naturally it tipped over and all the parts except for the command module exploded as it rolled down the hill.   But the command module survived and left Jeb and Bill stranded on Duna with not much space to live in.

    I watched some youtube videos then sent Bob back in a simply designed lander build around the Mk 1-2    Landed it on the far side of the valley, attempted to fly across the valley but nearly destroyed that lander so Jeb and Bill walked like maybe 20km across Duna to reach the lander and flew home, I was so happy when I made it off Duna major accomplishment.

    Oh good, I'm not the only one that had no idea what that meant. Explain? Nerd reference I'm missing here? 

    Star Wars VII Spoilers 

    Spoiler

    In the first act of Force Awakens, two different characters at different times escape dangerous conditions on the planet Jakku and make reference to wanting to go back to the same character leading that character to question why everyone wants to go to Jakku.

     

    Do you think humans could survive natural selection if we weren't intelligent?

    The problem with this question is we wouldn't BE physically human without our intelligence. And vis versa.

    Why do we have big heads? to hold big brains, well without the brain we'd have smaller heads, and with smaller heads we'd be able to fit down the birth canal fully formed, able to walk at birth like other animals. If we were born fully formed then we wouldn't need a social structure to take care of babies, if we didn't need the social structure, we wouldn't need ot be intelligent and if we didn't need the social structure we'd not need a month adapted to talking, so we'd have a mouth that could bite and attack.

    Our intelligence is the driving reason why we look like, without intelligence we wouldn't have these bodies.

    So there's something dented the tin can ? (well no blame fest but I hope it clears the RUD better than most of us in our saves). IMO as there's no possibility an LOX tank can overpressure without external feed (take to open air and you get boiloff instead), must be structural collapse.

    Failure of both the overpressure valve and failure of a cooling creating a boiloff thus liquid turning to gas that takes up more volume sounds could overpressure without an outside source.

    How does one actualy measure deltaV in non orbital or deep space flight? (In real life)

    I am talking about stuff probably 10-100x as far out as Voyager 1 and/or 2. Indeed, very very far out.

    And as far as I know, a star tracker is only good for getting orientation/attitude, not calculating a position fix.

    Trying to use a star tracker for a position fix would mean measuring the angular velocity of several stars, while actively stabilizing the spacecraft's attitude with respect to several (likely different) stars, and I just can't figure out a way to prevent those two systems from interacting in a way that makes determining position an incredibly difficult if not impossible problem. Additionally, the angular resolution to measure such small changes would require optics that have more in common with a space telescope than a simple star tracker.

    Possibly you could use the relative motion of stars to get a precise velocity with respect to the center of the galaxy, but again, it requires an incredibly stable platform and incredibly high resolving power in the tracking optics.

    Seems every time I go to solve the problem, I end up with needing an incredibly stable platform and gigantic optics to even get a rough estimate of the spacecraft's position AND velocity vectors at (nearly) the same time.

    Odd, it seems that I've just discovered that the Heisenberg Uncertainty principle can have large-scale effects, when I previously believed it to only need to be compensated for when dealing with atomic or quantum scale things.

    How precise are you needing to be?

    https://en.wikipedia.org/wiki/X-ray_pulsar-based_navigation

    There are a list of known stable pulsars that you can triangulate off of, these will be stable over geological timescales,

    By seeing which ones you're pointing at you get orientation, by observing the dopplar shift of them you can get velocity, and by triangulating the angle to multiple pulsars you get high precision* location.

    *When you're traveling distances measured in light years +-5km is high precision
