SpaceX gives up: catching fairings in nets.  Presumably "wet fairings" (plucked out of the ocean) are working well enough not to try to crash rocket parts into ships.

Nukes in Space: four figure Isp and waaay more thrust than ions? Sign me up!  Yes, thrust is still tiny, but nothing like the antfarts of electrical propulsion.

I look forward to more launches from vandenberg. Had some incredible sky shows pretty regularly a few years back...

Did you ever notice how these Ars Technica space links have a bunch of topics, like a Chinese buffet? Isn't it curious how few of them get commented on, or how few comments in total appear in one of these threads? Doesn't it make you wonder why that is? Why is it that I begin thinking like Andy Rooney whenever I see one of them? I liked Andy Rooney. I'll bet you read this in Andy Rooney's voice. I know I did.

Yup.  And it keeps going...  and going...  and going...

I've mentioned this before, so if you're already familiar with it, my apologies, but the novel 'Saturn Run', by John Sandford and Ctein, has a good (fictional, of course) in-depth comparison of Nuclear Thermal Propulsion and the proposed VASIMR engine.

It's a fun read if you're interested.

It's almost as if the linked website has a commenting system that doesn't suck.

I remember NERVA when it was the hot new thing.  Rather sad we gave up so much for the Space Shuttle.

...as well as the company's "inability to obtain needed regulatory documents from the Defense Ministry" for the design of a suborbital tourist rocket.

I'm pretty sure 'regulatory documents' are just a large stack of hard currency.

One of the headlines for Rocket Report had something to the effect of "these stories and Andy Rooney"
