Re: SpaceX News

Looks like the center core for the FH tipped over on the way back to port due to high seas, though. Apparently the OctaGrabber hasn't been reconfigured to hold down FH center cores yet, though its supposed to be ready to do so by the next FH launch.

Re: SpaceX News

Minor news: Looks like SpaceX has successfully started testing the Raptor engine in the StarHopper. It was a short, tethered, burn, but you gotta start somewhere with new engines and rocket.

Re: SpaceX News

As I understand it, they decided not to fund retropropulsive landing of the capsule so they could throw that money toward BFR (or whatever its called this week ;) ). If something comes up to change that, however, - say, NASA wanting to have Dragon 2 land on the moon - I'm sure SpaceX will be more th...

Re: SpaceX News

SpaceX DM-1 flight is to launch tomorrow (2 Mar) at 07:49 UTC (02:49 EST) from Florida, heading to the ISS (with a very small amount of cargo). If this happens, it means SpaceX got a man-capable capsule into orbit before Boeing could fly the Starliner. I won't be awake for this, but hopefully it wil...

Re: SpaceX News

Looks like a F9 will be used to launch a lunar lander tomorrow evening at about 1945 central (US) time. Hopefully I'm home from work in time to watch the launch (via PC).

Re: EMC2 news

Interesting read.

Is it me, or does this design seem to be about where Dr. Bussard was about 15 to 20 years ago?

Re: SpaceX News

SpaceCats preventing the mice from leaving? ;) Getting as much delta-v from the first/second stages will definitely save fuel (and thus delta-v) for the payload. Though, it won't take too much to circularize when you are up in HEO (lower orbital velocity, but more work to get up there in the first p...

Re: SpaceX News

The mystery to me is that this object seems to be ahead of the stage as the stage overtakes it. The stage has done nothing except a flip end to end while continuing on a ballistic path from MECO. That implies to me that everything that was carried along from launch, ice or whatever is ruled out bec...

Re: 2018 NIAC Symposium

It would be quite humorous if a man-made crystalline structure of paired lithium atoms turned out to be a key material for the Mach Effect device. :roll:

Re: Water based propulsion for deep space efforts

The Integral Trees and The Smoke Ring were two of my first Niven books. Very nice, especially with the way the denizens moved around in the environment. Of course, Footfall holds a special place in my heart due to the use of a real Orion spacecraft (even if it does point out why we never went far w...

Hadn't heard of it, but I found this article ( https://www.express.co.uk/news/science/976653/scientists-nuclear-fusion-method-limitless-energy-supply-decades ), from yesterday. Its very light on details, though the one image from what appears to be a powerpoint looks like they use neutrons for power...

Re: A blast from the science fiction past

I was refreshing my memory on the NSWR and got a chuckle from this line (from Wiki): "NSWRs share many of the features of Orion propulsion systems, except that NSWRs would generate continuous rather than pulsed thrust and may be workable on much smaller scales than the smallest feasible Orion d...
