The idea of landing the booster back on the launch pad and recycling it within 24 hours (implied) seems pretty incredible.  As in, I don't think that's a credible approach.  They're nowhere close to that level of precision in their landings yet.  Also, the potential for a pad accident to damage the tanker vehicle seems way too high.  It would seem to make much more sense to have two boosters and to launch the two rockets in relatively rapid succession, then recycle both for future missions. 

And I'm not sure why you'd launch the spacecraft with people aboard first.  Launch the tanker first and make sure you have fuel on orbit, then put the manned spacecraft up to rendezvous with it.  If the tanker fails, you can delay the manned launch until you have fuel available.

Does seem a bit illogical as any kind of issue with the tanker and/or booster is going to leave a bunch of colonists stuck in orbit with nowhere to go.

Two years ago pad landings were "impossible", let alone one on a barge floating at sea.
"DARPA Hard"  It ain't what it use to be.

Looking at the design of the interplanetary vehicle on its own I guess Mr Musk must have been a Dan Dare fan when younger.

With suitable fuel depot it is designed to reach Jupiter & Saturn.

Saw some figures on Musk preservation
http://www.spacex.com/mars


The Rocket is HUGE it dwarfs the Saturn V
As expendable it would carry 550 tons to Low orbit
Reuse and Refuel it carry 450 tons to Mars
passengers around 100 to 200 people !

Launch mass is around  10000 tons (NOVA Size)
lift off  by 42 raptor engine (Lox/CH4 fuel) in Booster (6700 tons) and 6 raptor engines in Spaceship (1900 tons).
Once refuel the Spaceship can get any were in Solarsystem and land there (it will take travel-time of Years) 
the Mars rocket build from Carbon-fiber material, they got already a LIFE SIZE prototype tank under testing !
and Raptor engine made first test firing

Time tabel ?
Vage but aiming for 2023, so NASA hurry up, other wise a private company land first on Mars...

What will be Zubrin reaction on that ?
i bet pure excitation...

Thank to NASA Space Flight Forum and Chris Bergin some picture

Quite a few of the questions in the Q & A were pretty dire.

As a Douglas Adams fan like the idea of him calling the first ship Heart of Gold.

Only requires a reusable rocket over three times bigger than a Saturn V, with 42 engines in the first stage.

Seems totally reasonable.

Actually it make quite sense

until 1964 NASA study for Manned Mars Mission, the use of a gigantic rockets called NOVA with payload on 400 tons in low orbit
To reduce the Launches to minimum Two or Three
SpaceX ITP goes same direction but with one big differences ITP is reusable, NOVA not !
and New Glenn from Blue Origin almost in size of Saturn V and  reusable...

Oh i yeah the current reaction at ULA, ArianeSpace and NASA...

"Dire" as in "Release the dire wolves on these fricken' morons. Who let these hippies, self-promoters and whackjobs anywhere near the microphones?"

This is in a sense the PR flacks worst nightmare. Sometimes a questioner comes along who is so awful that their awfulness rubs off on the questionee. Musk did a fair job of dealing with them by either not understanding them, or outright shoving them aside.

"I have a bus outside..."
"I'm sorry, that's not a hair question. NEXT!"

And so the endless circle of life comes to an end, meaningless and grim. Why did they live, and why did they die? No reason. Two hundred million years of evolution snuffed out, for in the end Nature is horrific and teaches us nothing

Honestly, I doubt those folks much care, except maybe NASA.  They know that the ITS, successful or not, is not relevant for commercial space launch services.  Demand for launches in the existing weight classes isn't going to dry up just because SpaceX can lob 400 tons at Mars every so often.  Heck, this probably helps ULA and Ariane because SpaceX engineering talent that could be refining a next gen Falcon Heavy successor will instead be designing the non-commercial ITS.

Here is the official slide set from the presentation including pictures of that monstrous LOX tank they've already fabricated.
