Re: Watch fourth launch of same gear Sunday

As soon as NASA vertically recovers and reuses one of it's boosters, I'll agree with you. I will partially agree with your statement that the NASA space program has been a joke since '72, but only in so far as the manned deep space program is concerned. Agree completely. I can understand GH's point...

Re: Watch fourth launch of same gear Sunday

While that is a lot of forward thinking for the methane engine, Blue Origin is looking to it more in the ease of reusuability aspect. The methane does not leave the deposits that kerosene does and would therefore make repeat uses of the engine much easier. Yes, the 'coking' problem. Evidently Space...

Re: Spherachutes

Is there a standard spill hole size or percentage? and do you know if different size spill holes can be accommodated? Are you talking about a "rule of thumb" ie theoretically, or the "ideal" size for a given chute, or are you specifically asking about these particular chutes and how they're designe...

Re: Watch fourth launch of same gear Sunday

Plus, methane engines are going to be a necessity if we ever plan to have any sort of "Mars infrastructure" beyond some "flags n footprints" type missions. Read "The Case for Mars" by Robert Zubrin on that count. Methane propellant is easily producible on the Mars surface using hydrogen brought from...

Re: Watch fourth launch of same gear Sunday

Oh, I agree... I just don't get too excited about "suborbital". Yeah, I know they do a lot of good work there, with sounding rockets and all that, and suborbital flight predates orbital flight by a considerable amount of time. I know that BO is working on more than just the (IMHO) stupid "tourist" a...

Re: Red River Delta Syx

Those steel rods out of the hangers from the store that have the two metal clips on them work TERRIFIC for aligning launch lugs-- they're about a foot long and 1/8 inch diameter, perfect for aligning lugs. I was hoping to salvage the clips as well-- if you slide them off the rod once you free it fro...

Re: Watch fourth launch of same gear Sunday

Looks... interesting. That's one word for it... I was gonna say it looks like a sex toy... LOL:) Instead it's a toy for joyrides for rich people wanting 4 minutes or so of weightlessness... Meh... I don't get excited about that sort of thing... SpaceX is actually doing things IN SPACE, ie, IN ORBIT...

Move along, move along....there's nothing to see here. It's official, there is no such thing as Islamic Extremism. We recognize no problem, therefore there is none. For those in charge now, we Tea Party types are a much bigger threat than muzzie terrorists....... Exactly... the muzzies are their fr...

Re: Gap staging vent hole size

I'd do two holes, probably about hole-punch size. I'd rather have the holes a bit too large than too small, myself. 6.35mm... that specific?? Wonder if that's the size hole left by a hole punch?? LOL:) On the Dr. Zooch Vanguard Eagle kit (which was designed and built as an actual functional two-stag...
