Nice to see Orbital ATK is back in the race after a 2 year absence. They launched an ISS resupply mission last night from Virginia. According to the article they are still using the Russian engines. Hmm!?
Here are Elon's comments in a recent Q&A @ Reddit. Click 'context' under one of them to get the sub-thread/detail. I'd emphasise an immediately relevant one :

Question :
Overall is the landing architecture of ITS booster and distances needed to be covered to be same as Falcon 9’s? Boostback, re-entry burn, landing burn?
Could you give us nuggets on what changes the ”final” Falcon 9 version (”v1.3”) you mentioned will have? Uprated engines obviously from 170k to 190k lbf, but what else? Is it mostly geared towards reusabilty over performance?
Gwynne mentioned 2 weeks ago that F9 v1.2 will be reused only once or twice while ”v1.3” should be reused up to 10 times. Can you talk about what are the limiting factors for Falcon 9 reuse?
Elon :
The big booster will have an easier time of things than Falcon, as the mass ratio of the stages is lower and it will have lower density. Net result is that it won't come in quite as hot and fast as Falcon, so Falcon should be a bounding case on the big booster.
Final Falcon 9 has a lot of minor refinements that collectively are important, but uprated thrust and improved legs are the most significant.
Actually, I think the F9 boosters could be used almost indefinitely, so long as there is scheduled maintenance and careful inspections. Falcon 9 Block 5 -- the final version in the series -- is the one that has the most performance and is designed for easy reuse, so it just makes sense to focus on that long term and retire the earlier versions. Block 5 starts production in about 3 months and initial flight is in 6 to 8 months, so there isn't much point in ground testing Block 3 or 4 much beyond a few reflights.
Cheers, Mike.

The other Tesla news for this week is it's operating profit for Model S activities : $22K USD per car ( ~ 27% ) on a $2.3B turnover. So some $600M was used to retire debt, some current and some future. Careful with the wording of reports though, much word-smithing and deliberate fudging of traditional/accepted accounting definitions from people who really should know better : gross is not the same as nett, capital investment is not an operating loss, profit for a single product is not the company profit, etc.
Current stockholders equity is ~ $1B on ~ $7B liabililty ie. about ~ $8B assets ( book value of course ). It has the typical problem of start-ups with such gearing : their stock is usually shorted in the immediate term ( especially if one has inside knowledge with regard to timing of outlays ). There are no earnings per share yet as no dividends have been distributed and probably won't until ~ 2020. If you want to buy then do so for the longer term eg 5+ years.
I've been following the installation of charge points in Victoria ( Australia ) : only five superchargers ( along the main highway to Sydney ) but around 50+ at destination ( typically higher-end resorts with overnite charging added to the accommodation rates ). So to have such destination charging at a motel that you own then "Qualified properties will receive their first two Tesla wall connectors free of charge as long as they are installed in visible or convenient locations. " The electricity isn't free, of course .......
Cheers, Mike.

I thought Model S and X visits to superchargers were free (included in price). source
Superchargers are free for Model X and Model S, but it will come at a cost to Model 3 owners.
I guess even for Model 3 the cost is is still a lot less than fuel.

The 'destination' chargers are slow/overniters ie. not for the 20-odd minute fill-ups that the superchargers which are owned etc by Tesla.
Also I forgot ( what your article mentions ) that the forward sales value on their order books is about twice the company's current capital value. While a pie-in-the-sky calculation, if you translate via present production profit then you have repaid half the asset outlay existing at the moment. So the next question is how quickly can you make all those cars .....
..... while all the customers/investors may be labelled as fools, the fact is that Tesla continues to raise money via shareholdings or sales despite having almost no traditional advertising. This is annoying more than a few pundits. As an investment comparison Telsa is risk rated in the category of say, new mining schemes and for much the same reasons : high asset investment now and the profits later on ( medium to long term ) but only if a future market deems value in what you dig up then. Short answer : don't invest more than you are prepared to lose, at best in the near term you'll get $1 in $7 back if they go belly up.
Cheers, Mike.
( edit ) Of course the other trick is ".... in a gold rush, sell spades .... " ie. bet on the inputs. Anyone for Lithium stocks .... :-0

Ah, missed that, that makes sense.

Lithium prices and battery manufacturing are pretty secure futures i would think. Lithium battery recycling is quite a way behind, compared to lead battery. I don't know if this is a hidden future cost for Tesla, (manufacturers must factor recycle costs) certainly this will be a growth area as well.

Well there's a lithium rush DownUnda and it turns out there are gobs of places to find it in. Sediments abound .... it's an ancient continent & ex-inland sea. As usual it depends on extraction costs vs. price to determine the game. Some of the big miners with existing holdings/leases for other metals ( iron, copper, aluminium, nickel, silver ..... ) are even raking over their tailings dumps ! Fortunately some geological locations happen to already provide sufficient concentrations. Given that lithium is way less toxic* than the heavier metals, not much, if any, needs to be outlayed on that ground. One warning ought be said : the quality/purity of the product may well outweigh quantity in the market place when it comes to a sale. Consumers don't tolerate burning batteries.
Cheers, Mike.
* Meaning that when not deliberately ingested in bio-available form eg. lithium carbonate on medical advice.

Related only in that it involves Elon, his major announcement about Tesla scheduled for this morning has been changed to Wednesday.
