There were a bunch of individual "reuse" threads, so creating a catchall here as undoubtedly the records will continue to climb, as SpaceX is now certifying boosters for up tp 40 reuses... B1062 gets its 20th launch (as @Grendal mentioned in his launch announcement) Ars article about it here...

I realize that the 10,000 m/s number was just wild guesstimate, but I wonder what the practical limits of this tech would be... Given liquid chemical exhaust velocity is around 4.4Km/s which therefore limiting the total delta-V than can practically be achieved, this will be interesting to see...

Inserting an image, either via Cut-n-Paste or file upload, appears to be broken... a few of us noticed beginning over the weekend (of course it may have started earlier). Interestingly, the pasted pic initially appears in the body of the post with resize handles, etc.. (after a long pause), but...

(General thread for SpaceX developments at KSC, although this first post is specific to SLC-40) So, SpaceX has been making upgrades to SLC-40 at KSC, and recently tested the pad-abort escape system... a fun watch:

Just in case folks were unaware... Voyager 1 has had a communication issue with garbled telemetry since late last Nov. The last JPL update was Dec 12th. We got a bit more detail in an Ars Technica article a couple weeks back... but that's it. There have been issue before that have taken a...

Didn't find a "Merlin Reuse" thread in a quick search, so now we have one.

Sometime within the last week or so, when using Edge posts with links to twitter.com are navigating to there (and hence away from TMC) within the same tab. This is as opposed to opening a new tab, which was the previous behavior, and still is for other sites. Safari nor Chrome seem to do this...

So we have a Non-SpaceX Launch Vehicles thread, but this is a Non-SpaceX Additional Stage, so it would seem a different category, hence the new thread... Tom Mueller, has moved on from SpaceX, where he developed the Merlin engine, to Impulse. Here's an interesting Ars article discussing Helios...

Cool video on the 8th anniversary of the first successful Falcon 9 landing: Hard to believe it's been 8 yrs ago already... (and I also dug up a thread on the landing at the time, but it was specifically some helicopter footage, so created this new one...)

Seeing as how there's a thread for Blue Origin - New Shepherd, and this isn't a "versus SpaceX" topic, here's a thread for New Glenn. According to this Ars article B.O. seems confident New Glenn will Launch in 2024, and it will need to if it wants to make the August '24 launch window for Mars...

Will be interesting to see how accurate these may be: Crash CT Sims IG post

Not SpaceX related, but interesting: NASA Funding Development of “Game-Changing” Rotating Detonation Rocket Engines - The Debrief (on edit: Gah... that title should have been "funding"... I thought I used to be able to delete my own post, but can't seem to... Mods, you mind correcting? Thanks...)

Tim Dodd has an interesting video on Ursa Major, a rocket engine developer on his Everyday Astronaut channel: Some interesting tidbits: Their rockets are all staged combustion (and one closed catalyst cycle) Their first 2 (1 in production and another in dev) are oxygen rich, which is a...

Was the commentator for that ULA or Amazon? They specifically called out passing the Karman line... seems to be a bit of an obsession for Jeffrey's rocket endeavors... 😝

Might as well put her to work:

New player in the charging space?: Nxu Charger Field Tests Light on details... The "up to 4.5 MW of bi-directional DC power" spec is obviously total system power capability... for how many stalls? And "bi-directional"? They say initial tests up to 700KW.. the implication is that a single...

Brilliant piece by Engadget:

Supporting anecdotal data point: This whole "charging at home" thing was very new and the implications relatively unknown back when I bought my S in early 2013. Would I need fast turn-around to add range for unexpected events? Thus I opted for the twin on-board chargers. The Gen1's each could...

So for some reason an embedded image gives me this broken image icon: The text string is the image name portion of the URL: However, I recently realized if I right click on the broken link and "Open link in new tab", that works: But, it's obviously my browser loading the image directly...

(Splitting off replies from Investor Thread) My Panoramic Sunroof appears to have about the same area as the all glass roofs. Is there some other distinction? My 2013 has been flawless, despite a lot of use. (I should probably apply some conditioner to the seals... any recommendations?)

We've had a bit of debate discussion in differing threads (primarily SLS) about the potential for there to be mgm't level decisions that put other priorities over safety, given NASA's track record. The recent Ars article by Eric Berger talks about some of that...

So Tesla just released a video on their heat pump. I question I had some time ago, but never got around to asking is: Does the heat pump also provide heat for the pack in addition to the cabin? The earlier resistive heater cars (like mine) had separate heaters for the cabin, and the pack. The...

Hadn't seen anything about this potential development: Flameproofing lithium-ion batteries with salt One question I have is, what impact does it have on the power/energy/gravimetric density of the cell?

This was funny... didn't want to clog up another thread, but saw this reply on a twitter post where Blue appears to (once again) be copying SpaceX in testing recovering fairing halves...

Haven't seen any posts regarding the recently released "Assessment of Light-Duty Plug-in Electric Vehicles in the United States, 2010 – 2021" report released by Argonne National Labs, which was referred to by an Ars Technica article. The article commented on "just 0.54%" usage being offset...

(continuing topic from the Investor Discussion thread) So, in watching Chuck Cook's latest video, I note that the median box, jumps around a bit, and the road median curbs are darn solid. The creep-wall is solid too. So I understand @Discoducky the idea that those are vector-space...

(Goofy post leading in to a holiday weekend) So... I got locked out of the house the other evening when I went for a walk to return and find my electric door keypad battery failed without the usual warning. I spent about 40 minutes trying to break in and was preparing to break a window, when...

I think I saw mention of this, but first time I've seen the video...impressive: I bet SpaceX would hire him based on that video as a resume...

(originally posted this elsewhere but no reply) So I don't have FSD (or even a car with the hardware for it). However I did buy Tesla insurance, and had safety score in my app for several weeks after purchasing the Tesla insurance. It also suddenly disappeared for me. When selecting it in the...

Watched this new documentary on NetFlix the other night (just before the GigaTexas Cyber Rodeo, actually). Pretty good... focuses primarily on SpaceX's journey to return the US to manned flight post-Shuttle retirement. Nothing ground breaking, but some footage/details I don't recall having...

Waymo "Not an AI" Update 20 million miles... *snicker*

Many here remember fondly Jack Rickard, of EVTV fame. I happened to be watching BBS: The Documentary Episode 3 last evening, and lo-and-behold Jack was featured in a good portion of it. Unbeknownst to me, he was founder of Boardwatch magazine and partner in BBSCon 30-ish years ago. He...

Guy I know who has a podcast is doing a project for the Fuels Institute. He asked me to do an interview. He got permission to post the segments on social media. Here's the first... I'm the second person interviewed:

Searched and didn't see anything on this... Went to re-register my Model S yester day here in NoVA... new $88 highway use fee/tax. I actually think this is a good thing.

Tried my A/C for the first time this year, only to have it blowing warm air. No warning indicators during driving. When I put it in park, the "dog mode" dialog box said it couldn't be enabled because of a fault. So the car is aware something is wrong. Left the door open with the system on, no...

Found lots of threads referencing lug nuts, but nothing that popped up specifically for this that I saw. My 2013 Model S w/ 19" wheels has the original "soft" lug nuts, and I need to replace them. A couple of questions: - Are the replacements from Tesla any better than the originals? - Any...

My 2013 Model S (MCU1) is currently failing to initialize Bluetooth ("Error initializing Bluetooth - Call Service"). Additionally voice command no longer work: holding the steering wheel button simply pops up the question mark/Try Again prompt on the dash. Reboots of both MCU and dash do not...

So, I'm looking to confirm the correct part # for the Gen 1 MCU LCD/touchscreen. Unfortunately the Tesla pats catalog doesn't want to show me any detail (it seems broken... anybody else?): https://epc.teslamotors.com/#/systemGroups/53890 I believe the correct # is: SX-MCU SUB-ASY, SHIP. OGS...

Friend of mine just curbed her gray turbines. Any good recommendations for repair in the NoVA area? Leesburg/Sterling is the more specific region. Thanks...

So in thinking about the aborted booster landing from CRS 16 a while back (the one with the locked grid fin that went in the spin), I have a question as to how it was corrected. From Elon's comments, he said the engine worked to overcome the rotation of the booster. The captured video does...

Brand new, received as referral, but already have HPWC installed. $450 for local pickup in Northern VA area (Ashburn)

… Nissan just dwarfed all the Tesla fires in the last 5 years ten times over: Nissan Fire(s)

There's been talk reconfigurable battery packs since the new "350KW" CCS chargers have been announced, and a few installed. Those chargers only can deliver higher power at upwards of 1,000 volts. Most EV's today are ~400-450V max packs. There's been some talk of reconfigurable packs that allow...

So I got a call from a Tesla Loyalty dude. It was a half-and-half- mix of asking for feedback, and wanting to get me an appt to drive the latest car and experience the improvements... a pretty obvious attempt to generate a sale. Afterward I asked about why I've been able to redeem my referral...

I've tried to keep up with the several firmware threads, and don't recall seeing this mentioned... With the latest build (2018.39.7), when attempting to scroll through my USB media by artist , the right-hand side alphabetical index is off by one. So if I scroll down to jump the "S" sectioning...

I chuckled:

So, in the spirit of not clogging up the Investor Roundtable thread, I'm starting a separate thread here where we can debate discuss relevant computer history as well what appear to be some strong opinions regarding some of the players... I haven't bothered to copy all of the existing relevant...

Opted to post my reply to @Krispykreme here for dear of retribution in the Investor thread... It may not make as much sense out of context, but here goes: Despite your condescending salutation to @mongo and claims of being in the autonomous driving industry, it appears your grasp on some of...

My daughter and I just took a ~350 mile beer-tasting trip down I-81 starting where I live here in the Northern VA are of the Mid-Atlantic region. We hit a couple of Superchargers along the way, and it got me thinking about the state of the infrastructure and how it's changed over the slightly...

So some time back there was a thread discussing Tesla's battery patents. Among them was a patent for an intumescent fire retardant (goo). It's layer(s) of material that expand rapidly during heating, thus extracting the heat from the cell and helping quench any fire. It appears that Tesla...
