  1. I find myself visualizing the entrance exam for @Ferdoni's Kerbalnauts; 1) Are you an enthusiastic person? 2) How do you rate your enthusiasm? 3) If Enthusiasm were a color, what color would it be? 4) What kind of enthusiasm do you most commonly sprinkle on your breakfast? 5) Are you at all, in any way, aware of what the word "sad" means?...
  2. It might have to be for rights reasons, but I'd find a way to buy Bob a massive steak dinner somehow anyway.
  3. My present game has been dormant long enough that I am already thinking about re-starting. Presently I am playing with life-support for the first time, but though I am playing with Antenna Range I didn't have "line of sight" ticked, which I now perceive to have been rather the torpedo in my efforts at simulation. If I restart, it will be at 10% science rewards and the correct settings for communication, and I will Treasure trying to do the most with the least, and see if I can do a Grand Tour probe with part count limits and with bargain basement engines. That will be Fun. :]
  4. At the risk of self-promoting a desiccated husk, ... I attempted something quite similar a while ago, and despite initial enthusiasm it gained no traction. However! I think it would be cool- for those who wished to add such a mod.
  5. I think this deserves some kind of award. Beats me what, but it does. *impressed slow applause*
  6. This is a fascinating conversation, and boy would I love working at a telescope if it were practical (it is not; children, life, ), but I think my very esoteric question doesn't seem like it can be answered. It doesn't seem there is a "photons/sec" metric for telescopes, one simply continues gathering light until you have gathered enough, whether that is a 12 minute exposure in the back yard or a 40 day exposure like Hubble Deep Field. Concerning KSP and astronomy, I added a mod that places a star system 10 trillion km away, and then didn't add any tech to my game that would let me explore it- and just "looking" in the tracking station didn't feel right. My solution? I orbited a massive "radio telescope" to posit that I *could* see the detail in the tracking center. I really look forward to JWST's first assessment of the local stellar neighborhood. If only somewhere we find a single pixel of the color green...
  7. Asked and Answered! Thank you!
  8. So, my KSP game is still on 1.1 (i think)- the version where things can't roll straight at 80+kph. I've been out of the loop for most of 6 months; does this mean there is a potential viable reason to delay or *not* upgrade my game to the current latest version? I realize it is a poor thing to ask such a question without knowing the exact version I am playing on- I will provide that tomorrow via edit.
  9. I started thinking about analyzing light from distant stars ([spectroscopy] comments took me to wikipedia and the Extremely Large Telescope and the canceled-but-brilliantly-backronymed Overwhelmingly Large Telescope), and realized it all came down to photons. Which got me to think- if one were analyzing the atmosphere of ProximaB 4 light-years away, how many photons are you *actually* talking about that pass through the detector each second? Millions? Thousands? Furthermore, how would this change, if I were looking at a - say supernova in the Andromeda Galaxy 250,000 times farther away? My layman's thinking of light says the farther away you get - like a fire hose- the less light is emitted at an angle which touches your detector. Do astronomers count, or care about, photons? - & do you need a minimal quantity to do spectroscopy, or (i wouldn't believe it) is *one* photon enough?
  10. This is exactly the type of thing I enjoy chatting about, so I'll chime in. My goal is exploration, so I will never attempt anything so grandiose as colonizing anything. I have yet to have a Kerbal more than dip its toes into interplanetary space, and am testing a Duna landing mission unmanned, though given what I've learned already I am pretty sure it will be back to the drawing board before I have even completed aerobraking. I generally try to let the contracts steer me, and suppose that various govt agencies and private enterprise are collaborating on the tasks. I love the game "as-is", despite the fact that I am still playing the version that doesn't allow planes to taxi straight. I also simply ignore contracts that are foolish. I generally let the "search for life" be my guide, or rather in KSP the search for a "benign life environment". Ultimately I imagine a manned mission to Laythe may be considered, but I am going so slow and cautiously that that is decades away from consideration.
  11. I normally ignore rescue contracts (other space agencies don't fit into my worldview), but when I saw one come up for Nina Kerman, I couldn't say no. She became my first Kerbal to step onto Duna, though that was in a pre-lifesupport game so I am not sure I count it as anything but a sim anymore. Nina is my daughter's name.
  12. :\ I'm sorry Arch. I tried to build it myself rather than DL the file, and after a very laborious deployment the darn thing broke, and I just didn't get back to it. I was worried about "version" issues- I should have just DL'd it.
  13. I think the real limit to this thread is "what's the farthest distance object you have modded into your game." For practical reasons, I presume you mean actual missions that you hope to get actual science from, so I will not include my Valentine System probe which has an intercept set up for about 43,000 years. ( *highly* doubt I'll have the patience to run the game for 3 months to get that one...) At that point it would be about 10 trillion kilometers though. I'd be interested in hearing what the longest anyone has planned a manned mission for that took life support into account though. If you're dealing with perishables, even 2 years would be amazing.
  14. I would pay serious $ for a coffee table book on the Kerbol system that was published in the approximate faux "1955-ish" era... I've said great work too much, but; great work Sir.
  15. I did a direct retro-grade probe insertion into Laythe at ~10km/sec and left my Jool Transfer Stage attached when I realized how insanely hot the entry was going to be, and was delightedly surprised when I realized it would survive. Mind, the retro-grade velocities being discussed here are almost twice what I encountered (and I wasn't risking any lives of course!), but the result might be reproduce-able. Especially if 3-4k of dV could be budgeted for terminal breaking, though I know that for the difficulty of the mission being discussed that would be an Awful lot of baggage to cart.
