So annoying that he said ' I won't go into too much technical detail now and will save it for the questions at the end'rage

Does anyone else get the image of an orca whale when they see the payloads?
I hadn't, but now you mention it. I suppose it's the dynamic shape and black accents. I always loved the white with black panels on the Saturn 5, which are there to show the rocket's rotation (a throwback by the German engineers to the V2). The solar heating did cause issues though.

When SpaceX first posted the completed talk last night on their website they hadn't edited it at all, so you had to jump 30 minutes to get to the actual start. Now, they've reposted it from the introduction and thankfully lopped off the entire idiotic Q&A at the end. I felt embarrassed for him.


Incidentally, Blue Origin is actually older than SpaceX (2000 vs 2002).

same I was embarrassed for the man...
The open question session at the end was a shambles. It seemed Elon left early. Questions about "would Elon come for a ride in his electric bus outside", the guy from burning man, talking about going for a st on Mars and toilets, the girl asking to meet him upstairs for a kiss??? WTF. Questions needed to be screened beforehand to filter out the utter morons and those just there to promote their crappy business ideas. Frankly it was embarrassing.

Some kind person has mercifully done an edited Q&A video with all the nonsense cut out:

Surely they'd have a winch and cage rather than a scaffolding stairway for access to the passenger compartment, especially as one would be needed anyway to offload cargo ?

Its just an artists impression really, you wouldnt have the buildings that close to the rocket etc either.

Not too dissimilar to the space craft depicted in The Martian movie.



The powerful storm at the start of the book & film was more for dramatic effect and story reasons. It seems that wind isn't generally that strong on Mars due to the thin atmosphere. Apparently the strongest wind speed the Viking Landers registered was 60 mph, but it averages about 20 mph, a mere breeze. So getting lowered 162 ft down the side of a rocket shouldn't be that tricky. A bigger problem will be periodic dust storms which will blot out the sun and get into bloody everything.

The wind velocity can be quite high but theres very little actual atmosphere so its force is pretty puny.

Andy quite openly admits the storm that caused the Martians initial problems is total fiction.

How cool would it be to fly to mars in this, then refuel it on mars, then fly it back to earth and land it at Kennedy for the return trip?!

It (the BFS) has more thrust than a F9H on its own biggrin

No one can ever accuse Musk of lacking ambition, that's for sure.

I really want to see one of these things take off... and of course land a few minutes later. I may have to take a trip out to Florida when they're ready to go. A friend of mine has seen two Shuttle launches and said they were amazing.

I was thinking the other day that the word "launchpad" is set to become redundant. Perhaps "rocketpad" is more appropriate, in the same spirit as "helipad".

Take a week or so at Florida and watch all 5-6 launches ?

The spaceship needs 4-5 refuelling trips ( 380t of fuel per launch, 1960t fuel capacity)

Could do. It'll be some event.

Even building something that big is a task in itself. Musk mentioned in the Q&A they were looking at Michoud in Louisiana. That'll be the NASA Assembly Facility in New Orleans, which built the Shuttle's external fuel tanks and the first stage of the Saturn V. They were then transported down to the nearby docks and sailed round to Cape Canaveral in a specially adapted ship. Or by barge up the Mississippi for testing at Stennis Space Center.

The Saturn V's first stage was 138.0 ft (42.1 m) long, but the ITS booster is nearly twice as long - 254.3 ft (77.5 m) and about 6 ft wider.

Great write up on the waitbutwhy website.

I really can not believe I'm likely to see this in my lifetime.

I expect some of those dates to slip a little. Or even maybe a lot, but it is amazing.

Got a little emotional reading it.

An EM project were the dates slip... that's never happened before ;-)
(Although tellingly he seems to bring it home in the end)


As per the above Martian comparisons- if the first mission doesn't include a sack of spuds someone at SpaceX will probably get fired, they are all the backup you need...

Agreed. I really hope we (or later generations) can look back at this moment and say "that was when it started, that was when the colonisation of Mars became the reality it is today".

Am I the only one who gets, and still gets, shivers and a tear in my eye when I watch the booster landing back on earth?
