Re: SpaceX News

A quick google disclosed that the weight of the 4 landing legs of the F9 is around 2500 Kg which is a little bit more than 10% of the empty weight of the F9 rocket and 20% of LEO/ 50% of GTO payload. It is a bit less than 10% of the whole rocket. The second stage has about 4 tonnes, the first stage...

Re: SpaceX News

Slipjack has conjecture about increased clearance that I do buy. Still, fins would not be needed for increased leg length, only longer legs. From a static, dynamic and mechanical point of view, the fins are a much better solution than using longer legs in the original position. Indeed, with longer ...

Re: SpaceX News

It is not just aesthetics. The new design has a much larger leg span, which means that the rocket will be more stable when landed on unprepared ground. The new design also increases the ground clearance a lot. That helps prevent damage from debris. The aesthetics part comes in for the 3rd "leg&...

Re: SpaceX News

An exciting update to break the tedium of successful launches today! Moon trip passengers (via BFR) to be announced Monday. Included is a render of an updated BFR design: https://pbs.twimg.com/media/DnA7hZgU8AAxfxC.jpg:orig All engines now look to be sea-level. Speculation is that the skirt around ...

Re: SpaceX News

Was surprised to see next on the agenda isn't until Oct6. I had thought things were supposed to be packed in pretty tight this month to the end of the year. My guess would be that the delay of Commercial Crew DM1 to November and DM2 to next year has something to do with it. The rest might be space ...

While our current #plasma generator Norman undergoes construction to double the power of its #accelerator #beams, TAE is already siting for the next machine, Copernicus - expected to achieve net energy gain in the early-2020s.

Re: SpaceX News

Article quote , not mine. but the heavy does have a clear defined role in the mars mission. Nope, the article is wrong. FH only had one potential Mars mission and that was Red Dragon, which has long been cancelled. Since then BFR has been the ship to do Mars. FH's main purpose now is to launch very...

Re: BLP news

More forward looking statements. Still in development (will never be out). New ways of doing things (of course). Can't see an actual timeline this time. They are "almost there" as they have always been. I still find it (somewhat) entertaining during a time of otherwise slow news. https://b...

Re: SpaceX News

Booooring launch today! Barely could see anything because it was dark and fogy.
Successful first stage landing, despite strong winds.
The fairing recovery did not work out because of the strong winds. The parachutes drifted too far off course, I guess. Hope they will have more success next time.

Re: Small Tri Alpha news blurp

It is not quite that simple. ITER is not just about building the plant in France. The ITER project has employed dozens of research labs all around the world and that research has contributed a lot to our understanding of plasma physics. The simulation software alone has helped a lot of private fusio...

Re: Small Tri Alpha news blurp

2019! SJ, I hope you are right. ITER will dry up immediately and funding will flow to the others (IMO). There may still be hope for Polywell. So many things will take place with such success announcement. I don't think that ITER will dry up. Rather, I think that more private investors will jump on ...
