I strongly suspect that during the design of Falcon Heavy, it became obvious that a unitized booster/spaceship was really the way to go.
Elon musk repeatedly said that getting 3 boosters to play nice together was "crazy hard". |

Looks like they'll be performing a short test between 1000 and 1600 tomorrow.

I've yet to be disappointed with the Space X Program.
Reminds me of growing up in the 1960's and closely following the 'Space Race' with my Father. Really inspired me, led to a great career in electronics technology. |

Repair on stainless will be much easier than repair of composites. I imagine a properly designed stainless booster (with the new alloys that they hinted at) will wear better, be more easily repairable, more easily upgradeable and easier to build right. Composites are not as rare or unknown as they once were, or as expensive, but stainless is simpler. |

Super fast travel using outer space could be $20 billion market, disrupting airlines, UBS predicts
UBS believes there will be very lucrative ramifications from the space flight efforts currently led by Virgin Galactic, SpaceX and Blue Origin.
A lengthy UBS report published on Sunday found that, in a decade, high speed travel via outer space will represent an annual market of at least $20 billion and compete with long-distance airline flights. Space tourism will be a $3 billion market by 2030, UBS estimates.  Attached File |

https://twitter.com/i/status/1107378575924035584 NASA has a new innovation that represents an exciting leap forward in reusable thermal protection systems (TPS) technology. The Toughened Uni-Piece Fibrous Reinforced Oxidation-Resistant Composite (TUFROC) allows for much more affordable and sustainable operations involving Space Launch Services and other systems that utilize Earth re-entry vehicles. TUFROC has an exposed surface design and appropriate materials combination that will allow a space vehicle to survive both the mechanical stresses of the initial ascent and the extreme heating and stress of re-entry. It provides a thermal protection tile attachment system that is suitable for application to a space vehicle leading edge and for other uses in extreme heating environments (up to 3600 degree F., and possibly higher, for short time intervals)
Benefits Flight tested Survives high heat fluxes 3600 degree F. and above Light weight Modular, therefore easily replaceable Low cost to fabricate and maintain Easier to design - can be fabricated and tested in various configurations Reusable thermal protection system Provides a composite insulating structure |

1) is there only 1 raptor engine on the hopper?
2) Do they plan to land it like the boosters? 4) if so that would imply guidance systems right? 3) any side thrusters to control pitch and yaw stabilization? ( I think I’m using the terms correctly) |

I am VERY PROUD that the heavy open die forging, heat treating, machining plant where I retired from, young, Master E-Tech, EE, hosted a 'tour' of Elon's engineers, came through and we are producing 'parts' for them.
EGI has many specialty divisions, one of which is EQS, make specialty super high grade steel and alloys. Also sole producer producer of every penetrater bomb made, the 30,000 # was being made when I retired, sister companies do all the machining, ready to go minus the 'charge'. Loved working with the .mil-.gov folks. Know this as Wife is still there, in charge of ISO 9001 compliance, sure miss work, paid to have fun. Don't miss all of the check-the check of the check paper work. Awaiting 'lift off'. |

Quote HistoryOriginally Posted By 3Trip: One major Reason for using stainless steel for the booster not mentioned yet, is it’s stronger under cryogenic tempatures, so a fully fueled rocket is stronger when it’s needed, that means they can use less material & save weight. A metal one just goes to the scrap heap to be recycled. |
