    Is it just me or is the Dragon 2 Falcon 9 the most attractive?

    I have another Starship question. If Dragon propulsive landings have been abandoned due to regulations etc, wont the same issue be present for Starship? Or will it still propulsive land with people? Also if Starship has no cargo can it SSTO? I'm guessing not but I might as well ask

    I have a Starship question. The render of BFR a few months ago showed this ship with 7 engines. But if it only needs 3 to land, and as second stages typically only have 1 or 2 engines, why does BFR/Starship have 7 rather than 3 engines? I wouldn't have imagined it would need 7 for lunar lift off, but could be wrong of course!
  4. Well not much gravity especially considering the friction holding it there.

    So how high do I go to be considered out of the bowl? Also any recommendation on how to record for someone who has never done so (eg software).

    Mountain lake landing challenge

    Im making progress. Currently my plane has small girders underneath that have 80ms impact tolerance. Of course the rest of the plane doesnt have that much. My next design will be a probe core so I can rescue the Kerbal I stranded in the lake.

    I am still stuck trying to build a plane that will not disintegrate on touching water. Is using structural fueselage as pontoons not a good idea?

    Oh my, the pictures dont do it justice!! I sent a very high speed recon drone to have a look-see, approach at 190ms not a good idea. I need a plane that can fly at 40ms to land, and 1,000ms to commute there!! ITS THE TOILET BOWL OF DOOM!!!

    Slightly dumb question. How do you use coordinates to navigate on a planets surface?

    I read a book called MARS by Ben Bova in the 90s. It had a depiction of a reasonably realistic Mars mission in which they used a "two spaceship on a tether" gravity system. The advantage was that everything for the mission was doubled for safety purposes. I suspect that the weight of cable is a big DV downside.

    Who owns Telstar?

    Well this quote from wiki is what I am thinking: The law of salvage is a concept in maritime law which states that a person who recovers another person's ship or cargo after peril or loss at sea is entitled to a reward commensurate with the value of the property so saved. So whilst ownership is not transferred, there is nothing to stop someone going to take possession (if sunk or abandoned). I have a clearer understanding now than I did before this thread. With all things legal there woykd be many laws and loopholes.

    I dont think you still own a ship that sinks. Dont the laws of salvage apply?
  13. The space race had many benefits in terms of technological advances that help mankind. Also can you imagine not having detailed information on all the planets and moons? The solar system would seem so much more mysterious. Which brings my mind to considering whether the launch of space probes was part of the space race.... To actually answer the thread, I see it as a subset of the Cold War.... which is itself a major part of history.
  14. During the initial stages of reentry I realized chutes had not been repacked... So I sent out Bill (or was it Bob), who managed to repack one chute. Then the atmosphere started having an effect and the RCS wasnt strong enough to get him back in and he floated away. I switched back to the ship but wasnt able to get it to land on water so the other two died too as one chute was not enough. It landed NEXT to water...
