No matter how "out there" some of our rampant speculation posts are, Max Faget seriously proposed a swing-engine for the space shuttle.



A Relocated Main Engine Cluster For The Space Shuttle

It's a little more kerbal than what was built but the STS still had holes in the heat shield and quick disconnects for LOX and O2 lines.

Chinese Launchers / Re: ??? - KZ-1A - JSLC - November 25, 2018

I haven't seen any reference to this launch taking place. Is there any hint on the Chinese forums about this mission?

SpaceX BFR - Earth to Deep Space / Re: BFS Engineering Thread
« Last post by RotoSequence on Today at 10:40 AM »
I well remember the debate surrounding this configuration (even though at the time I was on the Boeing and then General Dynamics teams, while my colleague Max Hunter was on the MDAC team).  Max had argued fairly persuasively for a side entry SSTO configuration, basically similar to BFS, for a few years by the time the proposals were being prepared.  He also argued that the tank mass wouldn't be a major factor (in other words, that the common bulkhead was more trouble than it was worth – speaking from his S-IV experience as chief engineer).  DC-Y designers had little choice but to adopt the middle payload location once they committed to side (ultimately high-alpha) entry since there was no other way to balance the vehicle on entry (having ruled out canards, which SpaceX now seems willing to attempt).

With SpaceX "accelerating" BFR, the Falcon 9 S2 reentry demo cancelled, and fundraising reduced from $750 to $250 million, I wonder if they've decided to ditch the canards/brakerons in favor of a different (presumably lower risk) control scheme.

If LOX, CH4, and cargo were all cylinders (for manufacturing simplicity) could the bottom cylinder be the cargo bay and six engines attached to the outside in three nacelles? These three locations would presumably coincide with three major longerons and leg apparatus.

Maybe I'm reading too much into this, but this tweet makes me wonder.

https://twitter.com/elonmusk/status/1064741510560632832

I can't easily recall an occasion where Elon made a wholly untruthful or farcical statement about his businesses' interests or intentions. Does anyone have such a recollection to bring me back down to Earth?
Just add “(much)” to that tweet. It pretty much covers the future and keeps his statement true...

Where’s the face palm emoji?

Unless 'future versions' of the 'Starship' can reach at least 15-20% the velocity of light and has safe 'cryosleep' technology - it's all just aspirational marketing at best as far as interstellar missions are concerned...


The Starships would make good landers for a big Interstellarship. :)

Starship is a great name for the class of ship. Goes very well with a following specific name for each vessel. Starship Elon. Starship Kai. Starship Gwynne. Starship Donald. Starship Daedalus. Starship Arthur. The possibilities are endless and basically every name goes well with "Starship" in front.

Also, all-importantly, as mentioned above, it conforms with Hitchhiker's Guide to the Galaxy.

As for Elon's sometimes wacky tweets. The guy just has a surreal sense of humour, and a liking for hyperbole. No need to take everything he writes literally, like "going to other star systems"...

Does Musk observe the BFR/BFS nomenclature in his tweets?

We here routinely use BFR/BFS/BFB/BFC/BFD...  But I am not sure Musk always does.

Hmmm what were you saying about Elon not differentiating in his use of naming, well he certainly has now!

I dont think the BFR really had a name, just a nickname, now it's been named, possibly.

BFR > ITS > BFR > Starship (for now)

As I understand it’s the booster is now called Super Heavy & the upper stage Starship, making Starship Super Heavy altogether.

As somebody on Reddit observed: Finally a SSH connection to Mars.
So does that make the astronauts Troopers?

jsc2018e097261 (Nov. 19, 2018) --- Aboard a Gagarin Cosmonaut Training Center aircraft, Expedition 58 crew members Oleg Kononenko of Roscosmos (left), Anne McClain of NASA (center) and David Saint-Jacques of the Canadian Space Agency (right) affix a Soyuz MS-11 sticker to the wall of the cabin Nov. 19 in a traditional ceremony as they flew to their launch site in Baikonur, Kazakhstan. They will launch Dec. 3 on the Soyuz MS-11 spacecraft from the Baikonur Cosmodrome in Kazakhstan for a six-and-a-half month mission on the International Space Station...
