Yeah, I'd like to see her fly. But I'm not going to get all anxious, so many delays already. I won't be holding my breath for an August Launch... <div class="Discussion_UserSignature"> <font color="#ff0000"><u><em>Don't let your sig line incite a gay thread ;>)</em></u></font> </div>

Even more than the Falcon launch, i'm looking forward to Bigelow getting his test module up there.

Despite the fact that no capsules are involved -- I am indeed excited about this. Although I was also excited about the scheduled January, February, April, May, and July launch dates as well... <img src="/images/icons/smile.gif" /><br /><br />What I found more interesting in that article was the note about them completing their Marshall Islands pad at the Kwajalein Atoll. I was wondering about the feasibility of launching cargo/people to the ISS -- or Bigelow's CSS, so I checked the latitude. It's at about 8 degrees north -- so definitely not the best for the ISS. Pretty good for Geosynch, and indeterminate for BSS since we don't know what inclination that will have. <br /><br />However -- since the US has the Marshall islands, and Russia is able to use Kourou at 5.3 degrees N -- a commercial space station around that inclination might well be what he decides on. It will make for the most efficient launching of mass to orbit. Of course if he were to make it about 10 degrees south -- he would also make Woomera at 31 degrees S. a reasonable launch site in addition to the other two. Decisions decisions... <img src="/images/icons/smile.gif" />

That is to say, best in terms of payload lifted on a given launch vehicle. However there is a disadvantage in that launch windows are shorter than they are at a latitude equal to the inclination of the orbit (i.e. for ISS which has an inclination of 51.6 degrees, you get best payload launching from the equator but longest daily launch windows from Baikonur). I don't think the launch windows from the Marshall Islands or Kourou would be MUCH shorter than those from KSC though (although I don't have the numbers on that one).<br /><br />By launch window I mean the daily window, i.e. how many minutes each day you can launch, rather than how often those windows appear (although Baikonur is better for that, too).<br /><br />The absolute best payload for your money is achieved by launching from an equatorial site into an orbit with zero inclination. It gets worse if you move the launch site away from the equator, and also if you increase the inclination of the orbit. But an equatorial site is better than a high latitude one for the same orbit.

It's optimal for any inclination.<br /><br />A plane change from 0 degrees to 51 degrees at (essentially) 0 km/s is not equivalent to a plane change from 51 degrees to 0 degrees at 7.8 km/s. How would the Ariane 5 ES be able to lift 21 tons from Kourou to a 51 degree orbit if that were true?

Have there been any Shuttle missions where the orbiter needed to make a "significant" plane change? (more than just a couple of minutes of arc to clean up the orbit from ascent)

Yeah I agree .<br /><br /> A low-cost launch capability in private hands would be the best news for any of us space-fans.<br /><br /> I really hope they are able to pull it off . <img src="/images/icons/smile.gif" />

Well he has already stated that he wants to build a F1 class engine, (150000 lb thrust). If this engine were to be used as the current Merlin engine to produce a single engine heavy launch vehicle and a five engine super heavy launch vehicle what sort of scale vehicles would result?

Spaced_Case,<br /><br />I absolutely love the sound of 'big gulps'!<br /><br />The BFR rumors are beginning to sound much more true!

I must have failed in my copy and paste from astronautix <img src="/images/icons/frown.gif" />, oh hum. <br /><br />1,500,000lb thats a lot more thrust <img src="/images/icons/laugh.gif" />

If you go over to RLV News, you'll notice a quick summery of a Musk speech.<br /><br />Highlights:<br /><br />1. After the Falcon V, They plan to develop a booster to put 60,000 lbs in LEO.<br /><br />2. Target price is $500/lb by the end of the decade. <br /><br />A single F-1 class engine might be able to fit the bill for 60,000lbs. It seems like Musk is going to go after DoD contacts, (2010 is I believe when the current Dod contacts with Boeing and Lockheed are up until)<br /><br />Of course he could also follow the same development phase with going from a single engine to a cluster...I think we all know what that means.

GREAT!. <br /><br />Does anyone know what they will use as a first stage. Ie. what plane they will use for this launch? <div class="Discussion_UserSignature"> <p> </p><p><font color="#0000ff"><em>"SCE to AUX" - John Aaron, curiosity pays off</em></font></p> </div>

SpaceX launches are all from "ordinary" launchpads on the ground, they have not announced any intention to launch anything from the air.

Hmmm. I thought that was part of the design of the Falcon. <div class="Discussion_UserSignature"> <p> </p><p><font color="#0000ff"><em>"SCE to AUX" - John Aaron, curiosity pays off</em></font></p> </div>

One of the things that I have been wondering is the cost split between the first and second stage. If the first stage turns out to be reusable It would be nice to see it offered as a single stage sounding rocket or with a spin-stablizied solid second stage to put a few-100-lbs to leo.

OK I'm up to speed now on this rocket.<br /><br />just read : http://www.spacex.com/payloaduserguide.pdf<br /><br />Reliability. I can get behind that idea! <div class="Discussion_UserSignature"> <p> </p><p><font color="#0000ff"><em>"SCE to AUX" - John Aaron, curiosity pays off</em></font></p> </div>

I guess its not supposed to go into orbit but splash down. <br /><br />But maybe you can wait 20 years to recover it. lol, like the Saturn V part that revisited earth. But I think that was the 2nd stage and it went into a solar orbit. I still laugh at that.<br /><br />I guess - "what goes around, comes around" <div class="Discussion_UserSignature"> <p> </p><p><font color="#0000ff"><em>"SCE to AUX" - John Aaron, curiosity pays off</em></font></p> </div>

Is this the first cost effective booster at $5.9 million for a payload of 1480 lbs.?<br /><br /> <div class="Discussion_UserSignature"> <p> </p><p><font color="#0000ff"><em>"SCE to AUX" - John Aaron, curiosity pays off</em></font></p> </div>
