Guest Posted July 26, 2019 Share Posted July 26, 2019 I wouldn't be surprised if China has a reusable capability well before the rest of the west catches up to SpaceX. Good for them Quote Link to comment Share on other sites More sharing options...

(from here) That's obviously a bit different though. I don't think there's any other reason to put them on a rocket like that but to either divert it from populated areas and/or test reusability and/or both. Either way, exciting times ahead!

Generally I try to keep the signal to noise ratio high (except in SLS threads, I tend to bash it a bunch... I don't want to, but it's hard not to).

Yes, they can, and easily. But that is, I believe, a variant of the Long March 2C with the addition of lower fins, a solid interstage, and grid fins. The Long March 2C is powered by four YF-20s in the YF-21C configuration, which has no centrally-mounted engine and cannot downthrottle low enough for even a hoverslam. I am unsure whether the YF-21C config has relight capability. The engine schematics don't show burst discs or anything but that isn't always reliable. The YF-20 also has a very rough fuel-lean start, as shown by the big clouds of N2O4 that puff up around the base of the rocket at ignition, so trying to control the landing in a preferred zone seems hazardous...then again, so is just dumping the whole rocket onto inhabited areas. I would also guess they are testing for another project. Quote Link to comment Share on other sites More sharing options...

They are testing the ability to crash stages away from apartment blocks, etc, I think. (since they tend to rain them down in a decent sized CEP) Quote Link to comment Share on other sites More sharing options...
