Way to go SpaceX. Making access to space common place!

First launch I haven't seen in a while. It is like NASCAR without wrecks. What fun is that?
In any event, they deserve the honors accorded for coming so far, and so fast.
I am excited to see further Falcon Heavy progress, as well as BFR. Being on the ground for a BFR boost will be SPECTACULAR.
I'll have to find and watch the video of this last launch.

Booooring launch today! Barely could see anything because it was dark and fogy.
Successful first stage landing, despite strong winds.
The fairing recovery did not work out because of the strong winds. The parachutes drifted too far off course, I guess. Hope they will have more success next time.

Dang! Missed it. On travel in DC. Been pretty busy. Had some great discussions with a former Senator of note as well as a former AF Chief of Staff. We even talked about space. :)

But did you bring up the polywell and stump for it?

Oh... <yawn>... hey, it was the first Block V recycle. I wonder when the first "3rd Flight" will be?
Crew Dragon coming up soon. Then we can stop paying the Russians maybe. So friggin' sad

Especially since we can send up a Dragon fully crewed for what Russians charges for one crew member
this is an article that takes a shot right across the bow of the Nasa gravy boat
https://qz.com/1209330/spacexs-falcon-h ... -on-board/
The NSC does not know whether to shit or get off the pot.
Consider that SpaceX’s Falcon Heavy was built to help realize Elon Musk’s dreams of a multi-planetary civilization. it is expected to be able to deliver some 70 tons to low-earth orbit, or less than 20 tons to Mars, while costing around $150 million per mission
According to the new NASA budget released last week, SLS will fly for the first time in 2020, capable of carrying some 77 tons to low earth orbit at a cost of about $1 billion a flight. The total costs of the program are tough to estimate but exceed $10 billion
SLS will be more powerful, but the Falcon Heavy is here now, and costs less.

You are confusing Falcon Heavy and BFR. Falcon Heavy already launched earlier this year and is not intended for Mars missions. The ship intended for Mars missions is the BFS (the reusable second stage of the BFR) and that has a payload to LEO of 150 tonnes. Plus it can be refueled in orbit in order to take the same amount of payload all the way to Mars. Launch cost for BFR is expected to be lower than for Falcon Heavy and even than for Falcon 9 at less than 5 million per launch. BFS will start doing suborbital test hops as early as next year and BFR is expected to have a first launch in 2020.

Article quote , not mine. but the heavy does have a clear defined role in the mars mission.

Red Dragon” was a thing up until recently— intended to deliver cargo to mars via F9 Heavy.

Nope, the article is wrong. FH only had one potential Mars mission and that was Red Dragon, which has long been cancelled. Since then BFR has been the ship to do Mars. FH's main purpose now is to launch very heavy payloads to earth orbit, particularly for the DOD. SpaceX needs to have heavy capabilities in order to be a valid competitor in that market. Once BFR comes online FH will be retired and Falcon 9 will follow suit some time after that with BFR taking over the entire launch business for SpaceX. In a sense FH is a stopgap measure until BFR becomes available. F9 has some more value because of the many NASA contracts that are set on F9.

That does sound like a more reasonable launch model but I would not count the block five out for the next ten years minimum in the falcon and the heavy configurations.There are several near earth mission involving resupply and crew transport for the Mars and Moon missions that are on the books (postulated anyway) The company now has 6,000 employees, and just meeting that payroll and keeping facilities in California, Texas, Florida, and elsewhere operating probably costs on the order of $1 to $1.25 billion At a rate of $62 million per launch, it would take 20 launches a year just to cover these expenses.(not my figures but they sound reasonable) The only way to keep baby wearing new shoes is to keep the falcon series hot and active. This also explains many for the new upgrades that went into the block five. For one the welded octawab faster to produce and lighter but the bolt on allows better ability to reconfigure for different missions. The tyranny of the rocket equation means to go for a heavier design there must be a cost saving of a factor in the production / inspection cycle. The Titanium grid fins for unlimited re-uses is another good example.
while I want to see the BFR out there and flying the truth of the matter is right at this moment it is not needed, but as soon as the SLS is a "go for flight" the BFR has a mission at 1/4 the cost per launch to nasa.
No matter how many friends of NASA exist in congress the bean counters will force the way to commercialisation and once the monarchy of to the moon nasa administration dies out or is replaced they will realise that they can do so much more science on their budget if they just get out of the rocket business
