Looks like its going to be totally packed, not a seat left empty.

I assume someone's going to cover this given the duplicate thread in the live section? (I'm busy - ironically with other commercial stuff

Later this year or early next year. Raptor?
Reading between the lines, that might mean Melin 1d is close to being done.

Looking at systems to deliver 50mt to Mars, fully reusable. Nothing fleshed out yet though.

Elon Musk cut to questions rather quickly, looks like this will be very much a Q&A session:
Discussing human rating of Dragon, escape systems and vertical landing.
Electrical propulsion a good idea for trip to Mars, needs to have enough thrust to matter and energy efficient.

Answering a question about lifting body designs. Not optimized for Mars and useless on the moon. Dragon capsule design more flexible and stable / safer.

Interesting comments with the FH cross feeding. The cross lines might be after the manifold, not before.

Crossfeed on Falcon Heavy useful for missions with heavy payloads, will probably be disabled for smaller payloads.
In discussion with NASA about missions beyond Pluto, would probably use crossfeed for that.

How is it going with reusability?
So far it has sucked. (his words)

Tricky thing about nuclear propulsion is getting the reactor and uranium into space. Public will be hard to convince, safety issues. Another issue is weight, reactors are heavy, need cooling, etc. Solar panels are great. Reactors on Mars may be better, waste heat is useful there.

This is turning into a nuclear propulsion roundtable now.

Q: ISP improvements outweigh the extra weight of nuclear rockets. Amount of radioactive material small.
EM: Maybe ok for upper stage, worried about public reaction, does not want to be lynched! ^_^
Q: Will be inert until in space, so little radioactivity.
EM: What if there is a crash?
Q: Can be contained, minimal radiation risk.
EM: Maybe this is worth looking into, will talk about this later. Maybe if public can be convinced if its safe then it might be a way to go.
EM: Fusion would be cool, needs to work on the ground first, would be a boon to humanity even if just working on the ground.

Permanent Mars / Earth ferries may have a place in the long term. Initial thoughts are towards a one mission infrastructure.
Funding for Mars would probably be a combination of government and private. Would make one hell of an x-prize!
Keynote concluded.
