    The news is actually a few hours old but finally there's pics.
    Second stage still in orbit has performed successful restart and is now in an orbit with an apogee of 11,000km.

    great - more space junk

    The apogee is 11,000km but the perigee should still be fairly low.
    As shown in the first pic.
    The stage should still deorbit in a month or two due to high atmospheric drag at the low point of it's orbit.
    The same goes for it's secondary payload several nano satellites since they lack a means for a third burn to circularize their orbit.
    Com sats need to perform one or two large burns at their apogee to circularize their orbit as shown in the second pic.
    What Space did was demonstrate they could place a secondary payload in a different orbit then Dragon potentially a very useful feature.

  3. If you think about it in real time, create a big enough spaceship(biodome example), send a bunch of fertile people into space, make them mate for thousands of years in space, return to earth, and look at the sad retarded incest babies.

  5. So long as the 2nd stage doesn't bump into anything while its still up there, or gets hit by any high velocity junk bits (which will turn it into more bits). Until such time as it actually comes back in a blaze of pretty burning bits. Its still a big hunk of space junk.

    Regarding the secret payload on this run,... I think the next secret payload that they're going to send to the ISS on their alleged "dry run".
    Will consist of a bit of cheese, some sausages, a case or two of champagne and a keg of beer. To celebrate the successful mission.
    (f.y.i. booze is supposed to be forbiden on the ISS)

  7. Two thousand years ago, a Greek mechanic set out to build a machine that would model the workings of the known Universe. The result was a complex clockwork mechanism that displayed the motions of the Sun, Moon and planets on precisely marked dials. By turning a handle, the creator could watch his tiny celestial bodies trace their undulating paths through the sky.

    Like in Wall-E, we'll all become too fat to walk, and forget all about face-to-face human interaction.

    Sooo.. in other words there will be almost no change for most of the members here on Sankaku.

  9. I'd have to say that the best hope right now is Virgin Galactic. They've been making steady progress (http://www.virgingalactic.com/news/item/vss-enterprise-completes-first-manned-glide-flight/), and there are people who are actually booking flights with them. Space X is nice, but rockets are terribly inefficient, in fact I've heard that the Space Shuttle was originally intended to be launched from carrier aircraft (similar to how the things get transported today), but I haven't found any corroborating evidence. In any case, most solutions relying on current technology are at best a stop-gap until we manage to come up with a truly efficient technology, such as a space elevator.

    We're making good headway towards being able to make cables strong enough to produce a space elevator. When I first entered college (already seven years ago!) carbon nanotubes were considered more valuable than gold, but now they can be found in all sorts of products, ranging from paints to carbon fiber hulls for jetskies. When we learn to produce long, defect-free nanotubes with kilometer lengths cheaply and efficiently full scale space colonization will become feasible. The remaining problem that I see is political: where do you put a space elevator that won't upset someone, and how do you protect it from attack? Simulations have shown that the base needs to be located within 30 degrees of latitude of the equator (the closer the better), otherwise oscillations within the structure lead to catastrophic failure.

    Finally, for long-term space projects to ultimately succeed, there needs to be some sort of payoff. The only truly long-term reason I can see to maintain a space program is that we manage to find large quantities of readily accessible resources in space, say mass quantities of copper or rare earth resources. Also, keeping super-conducting devices at temperature should be cheaper in space. Dealing with overpopulation by moving people to space or other solar bodies (read: the moon, mars, asteroid colonies, etc.) will be too expensive to be feasible for the foreseeable future. Terraforming a planet into a second home is well beyond current technology (mars lacks a magnetic field to protect an atmosphere, the moon's gravity is too weak, and venus's atmosphere is just too hostile). "What if earth becomes unlivable" fails because the people who are willing to colonize without the possibility of a return trip to earth can't get funding. Finally "it's cool" and "let's do it for science" lead to programs like NASA: political pawns.

    Oh, and the ISS is cool, but fails on being unable to simulate gravity (therefore leading to boneloss) and needing a fuel supply to keep it from succumbing to atmospheric friction. The only three things it's good for are: research, a waystop, and space tourism. A spinning station is best for a long-term solution (unless someone manages to figure out some sort of artificial gravity that doesn't rely on constant acceleration).

  12. New spaceship from Orbital sciences and it's a mini shuttle.

  13. little by little space is starting to become a market boom my question is how much will said tourist have to pay to enter that shuttle as i imagine it will not be cheap

    Posted 5 years ago # Quote
  14. No it will not be cheap at first as it needs one of these to get into space.


    Though since it carries more and is reusable it should be cheaper then Soyuz.

    Plus it can supposedly use any LV with a large enough payload for example if OSC designs a better upper stage for Taurus II they may use it instead.

  16. That NASA clip made me lol. Must be from the 70s, maybe 80s? The really sad thing is we could have built that thing, and more. Much more. If it wasn't for...politics. People really disgust me sometimes. Ok, all the time.

  17. Damn, I can't see the moon from my window. Guess I'll settle for live stream. Or maybe I'll go out later. What time does the eclipsing start for the east coast?

  18. it starts now

  19. I went outside to look at it for a bit. Then came back inside. It's cold out. Took a pic for you guys.
