Re: Is it hype? or a possible real answer?

13 kilowatts= about 17 horsepower (1kw=1.34 horsepower) Saturn V= 150 MILLION horsepower. SO, I think they've got a long way to go. It doesn't really add up. Lots of folks have riding lawnmowers with bigger engines than 17 horsepower. Now, imagine trying to accelerate something the mass of a fully l...

Re: Is it hype? or a possible real answer?

Thanks for the vote of confidence... On my way to Indiana so I might not be able to check in for a day or two. Yeah, solar electric is of limited use for deep space, particularly for propulsion of manned missions. It has its place, but manned operations probably aren't it, at least not in the "stand...

Re: GHrocket who?

Yeah, GH is something else. Stuck at that "14 year old" level of humor, but he DOES know his stuff pretty well. Don't always agree with him by a longshot, but his comments DO make me think. I like someone who isn't afraid to call it like he sees it, and let the chips fall where they may. I can respe...

Re: E9-4 CATO

In fairness it's been fairly common knowledge that the black powder Estes "E" motors have had their troubles. Remember that Estes' first foray into the "larger than D" motor territory (for black powder motors in 'recent' times anyway) was the E15, which had so many problems they were quickly pulled ...

That's true, but won't do much good if this one sinks out from under them before it gets here.

Re: 10 Most Anticipated Science Fiction Movies of 2016

"Passengers" might be mildly interesting. Depends on how similar it is to how "The Martian" was done. Keira and I both loved "The Martian", although we both discussed a few technical inaccuracies we noticed-- I made her calculate WHY you couldn't use a drop cloth and duct tape to replace a missing h...

Re: Barrack to the people, don't worry about Hillary's server.

Ask Eric Snowden... Gee, Mistuh Prez... "there's *classified* and then there's "classified". Hmmm... like our nuclear launch codes are "classified". Obviously we don't want some raghead launching our missiles... Then there's "classified" like who knows what that was on Hillary's server. Who knows wh...

Re: Omitted information on Blue Origin landing number 3

Oh, I forgot "fourth" above, and since I don't see an 'edit' button... Fourth, methane is fairly easily attainable for in-situ resource utilization for deep space missions. (ISRU). Robert Zubrin built a "pilot plant" for turning the commonly available CO2 of the Martian atmosphere into methane rocke...
