RealKerbal3x Posted November 25, 2019 Share Posted November 25, 2019 Is CRS-19 the last Dragon 1 mission, or will that be CRS-20? Quote Link to comment Share on other sites More sharing options...
zolotiyeruki Posted November 25, 2019 Share Posted November 25, 2019 Is anyone else having trouble parsing this tweet? Quote SpaceX’s Dragon capsule will carry new cutting-edge to the research in an upcoming launch. Should that be "SpaceX’s Dragon capsule will carry new cutting-edge research to the ISS in an upcoming launch."? Quote Link to comment Share on other sites More sharing options...

Looks pretty perfect for starship except that you need to move the entire structure and weld on the complex bottom bulkhead, but you need an bottom on an tank to. One issue might be that starship will probably use thinner steel higher up as most of the load is fuel an oxidizer. They are not using this in Florida but the new segments are one continuous plate welded in an circle. Quote Link to comment Share on other sites More sharing options...

There's talk that the existing rings are being scrapped and the new ones are taller. The taller the rings, the fewer welds. Dunno, we'll see.

Ultimate Steve Posted November 26, 2019 Share Posted November 26, 2019 Not supposed to directly link to NSF images, so here's the thread: https://forum.nasaspaceflight.com/index.php?topic=48895.780 They are building a new bulkhead, presumably for Mk3. They are building a new tent, presumably for more construction capability or something. Mk1 is still on its pad but they have started working on it, presumably to move it and scrap it. And perhaps most exciting of all, there is a new ring there, waaaaay smoother than the others so far! Quote Link to comment Share on other sites More sharing options...

So do what you think is best. But legally, they have no ground to stand on there. If their webserver serves up an image, then it's fair game to link to it. That's the whole point of the web, in fact. I also just checked, and there is no KSP forum rule that forbids "deep linking" to other sites from here. Quote Link to comment Share on other sites More sharing options...

I think their primary concern is paying for bandwidth, but I agree, it's against the spirit of HTML (least the way we always thought of it in the old days).

tater Posted November 27, 2019 Share Posted November 27, 2019 (edited) Interestingly it looks like the CRS-19 booster will do an ASDS landing, not RTLS. Edited November 27, 2019 by tater Quote Link to comment Share on other sites More sharing options...

I believe CRS-19 will comanifest the privately-built Bishop Airlock Module in Dragon's trunk for permanent installation on the ISS. Gunther puts it at 325 kg which doesn't seem like much, but maybe it's enough that they need extra performance. Quote Link to comment Share on other sites More sharing options...

Maybe landing site is doing some Crew Dragon hotfire test, and having a Falcon 9 booster crash landing on top of it isn't a bright idea.

Ofc on the DEMO 2 mission the safety of the crew comes first, but as Spacex will have the cameras of the entire world on them, they probably want the booster landing to be picture perfect, as it is one of the trademarks of Spacex launches. So they are testing it now so they know every step in real life instead of simulating it Quote Link to comment Share on other sites More sharing options...

So they are testing it now so they know every step in real life instead of simulating it Makes sense, for RTLS require you to launch steep so you don't have to do an long boostback. This makes the ballistic trajectory after an fail steep to and you take too many g hitting the atmosphere. Same reason as Boeing uses two engines on the centaur upper stage for their capsule, however here you launch steep to give the centaur more time to accelerate to orbital velocity. With two engines the second stage burn is half as long and they don't need to launch as steep. 19 hours ago, kurja said: Depending on your jurisdiction (obviously), hotlinking images hosted on other sites may be considered "publishing", or "use" of that content.

Sites using adds dont like direct linking of images as they loose out the add revenue. It can be blocked but think this require some program checking who doing the request so few bother.
