Spectacular. Musk launched his personal Tesla in it with a dummy behind
the wheel. It will remain in solar orbit forever. Funny.

All three booster rockets returned to earth, two landing at Cape
Canaveral and one on a barge off the Florida coast. Couldn't see
the one land on the barge because the video feed was disrupted but
I understand it landed also.

I thought the sight of the two landing simultaneously at Canaveral was
almost as spectacular as the launch.

Me too. SpaceX has come a long way in a relatively short period of
time. Not to knock the accomplishments of NASA over the years but
Musk and Co. are making history. Love the sign on the Tesla dash.
"Don't Panic". Ha!

Also heard confirmation that the third (core) rocket landing on the
barge offshore was also successful.

I thought so too. The NK fat boy thinks it is cool to see 4 rockets
going up together but having 2 come down in the tail together is way
cooler.
I am curious how carrying the extra fuel and hardware to land a
booster compares to just dropping them in the ocean and building a new
one.
I know Carter's space truck ended up being much more expensive than
single use rockets. Some at NASA said it was sucking money away from
much more valuable programs. It drove a stake through the heart of the
extra orbital manned space program.
The main value of the shuttle is it was capable of bringing things
home although we deny we ever kidnapped anyone else's satellites. ;-)

It warms my loonytarian heart that private industry has stepped up to
fill the void our government has created.
This rocket is demonstrating that we might have a heavy lift rocket
capable of getting to the moon soon. I really hope Musk can get
something man rated that will get to low earth orbit soon so we can
stop using the Russians as our taxi to the space station.

The exact cost and savings are dependent on variables that are
currently unknown, not the least of which is launch frequency.

There's an interesting discussion he

Thanks for that link. I was surprised that the fuel costs for the first stage was quoted to be only $200-300k. I had to look up the engine technology and saw that they are LOX/RP (kerosene). That makes sense... it's a return to the Saturn V technology and what the Russian have never stopped using..

Really interesting stuff. I never got to see a Saturn V go up, but I did see the next to last shuttle launch. They are supposed to be mild compared to a Saturn V, which reportedly would break windows on the mainland. I'll make the trip to see a Falcon go.

Jet fuel? Ithiught they were all hydrogen gas. Didn’t know that....🤔

Not a lot of energy in hydrogen by volume. Even at 10000 PSI it has
less than a quarter of the energy of the same volume of dino oil.
160 years later, good old petroleum still seems to give you the best
bang for the buck.
