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...

Re: Forbes Article on Fusion

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...

Re: The list of duds

At least one of the data centers here in Austin TX has flywheel storage to supplement, if not replace, UPS battery storage. I'm not sure if they completely replaced batteries or not, however, as it wasn't the DC I worked in. From what I learned talking with one of the techs there, they are quite hap...

Re: Divertor Tokamak Test facility (DTT)

So, are these 7 years to "develop the device" part of the planned time for ITER development/construction, or is this in addition to it?

Re: SpaceX News

Depends on the payload. If its big enough then F9/FH won't cut it (though possibly only if they aren't willing to 'throw it away').

Looks like todays launch was aborted at T-58 seconds, and is rescheduled for tomorrow (11 May). Not sure on the time, however.

Re: Valaint

I've been through a couple of acquisitions (in the IT world) like that. Survived the first and second round on both, but it was not pretty. Good luck in your job hunting, as I recommend you polish up your resume and at least start looking now, even if you are not submitting for any until "you k...

Re: SpaceX News

An L4 + L5 interferometer would be nice. That would give it one hell of a base line, even if it was only two sats/scopes. More, obviously, would be better, though I don't expect that to happen any time soon.

Re: Mach Effect progress

Too bad it would be a royal pain to get one of the satellites he was doing station-keeping on to see how they perform on the balance with and without the transceiver running.

Re: SpaceX News

It also sounds like the Roadster was put in it's trajectory from just the two stages? Yes. The second stage did a burn about six hours after launch to push the roadster into a larger heliocentric orbit. The target was to put the apoapsis at Mars orbit, but with the fuel it had it ended up reaching ...

Re: Mach Effect progress

My understanding is that Elon Musk wants to invest in refining existing known good hardware that meets his personal goals, such as taking rockets and making them reusable. If someone developed and built a working, usable thruster - as opposed to a research build thats only really good on a test stan...

This was the first thing I thought of when I saw the shot of the Earth behind the roadster. Glad to see I wasn't alone in that.
