SpaceX is set to become the only company in history to launch the same commercial space capsule to orbit three times, a milestone of orbital spacecraft reuse in an otherwise ‘routine’ Cargo Dragon mission to the International Space Station (ISS).

Known as CRS-18, the mission will (hopefully) see Cargo Dragon capsule C108 and a fresh trunk deliver several tons of cargo to the ISS, SpaceX’s second of three such launches planned for 2019. Beyond Cargo Dragon’s third trip to orbit, building upon SpaceX’s inaugural commercial spacecraft reuse back in June 2017, Falcon 9 B1056.1 will become the first flight-proven Block 5 booster to launch a NASA mission, potentially setting the particular core up for many more NASA reuses to come. CRS-18 is scheduled to launch no earlier than (NET) 6:24 pm EDT (21:24 UTC), July 24th.

SpaceX reused one of its Cargo Dragon (Dragon 1) capsules for the first time in June 2017, becoming the first company in history to recover and reuse an orbital-class spacecraft, much like the company is about to become the first to reuse a commercial spacecraft twice. Speaking at the ISSR&D 2017 conference, SpaceX CEO Elon Musk noted that – despite the fact that it was the first time a commercial entity (including SpaceX) had reused an orbital spacecraft – the cost of refurbishing Cargo Dragon C106 was no less than 50% cheaper than building a new capsule.

The cost-effectiveness of Cargo Dragon reuse has likely only improved in the two years since that historic first, meaning that SpaceX’s ISS resupply runs likely feature some extremely healthy margins for the company. According to an exhaustive 2017 analysis of CRS costs, the total cost of a single Cargo Dragon resupply mission is likely ~$175M (FY19). (Zapata, 2017)

Aside from CRS-18, SpaceX has two Dragon 1 launches remaining in its original CRS1 contract with NASA. Both will also necessarily make use of twice-flown capsules like CRS-18, leaving SpaceX with a retired fleet of no fewer than three thrice-flown and three twice-flown orbital spacecraft as Dragon 2 (Crew Dragon) takes the reins. Current schedules show SpaceX’s final CRS1 launch – CRS-20 – following CRS-19 (NET December 2019) in March 2020. Cargo Dragon 2’s launch debut is currently scheduled no earlier than August 2020 and – as all Cargo Dragon 2 launches – will reuse a lightly-modified, orbit-proven Crew Dragon capsule.

CRS-18: bad weather in spades

CRS-18 will likely face some of the worst weather SpaceX has ever experienced during an attempted Falcon 9 launch, with July 24th and the July 25th backup window carrying probabilities of violation (i.e. a scrub) of 70% and 80%, respectively. In other words, there is a measly 30% and 20% chance that Falcon 9 will be able to launch CRS-18 this Wednesday or Thursday.

Supporting the Cargo Dragon launch is Falcon 9 booster B1056.2, likely to set the second-fastest Falcon 9 turnaround time with just 80 days between its May 4th launch debut and CRS-18. SpaceX’s turnaround record currently stands at 74 days – a three-way tie between boosters B1048, B1052, and B1053. Additionally, B1056’s second launch will also mark the first time that NASA has reused a Block 5 booster, an important indication that the space agency is extremely comfortable with SpaceX’s latest Falcon 9 variant and its associated reuse procedures.

Stay tuned as Falcon 9 prepares to go vertical at Cape Canaveral Launch Complex 40 (LC-40) and the Air Force Station’s final T-24h launch day weather forecasts begin to roll in

How to use Grok Bot to block spam calls and texts

Musk told users to ask Grok Bot to scrub their phone numbers from spam lists.

Published

By

Elon Musk has a new use case for Grok Bot, and it is the spam call. On Thursday he replied to an X user named Arash with a short instruction: “Ask your @Grok @Bot to remove your phone number from spam call & text lists!” Arash had said he got tired of the calls, had an AI bot find his number on listing sites and file removal requests, and packaged the process as a free skill for others.

The skill is called Spam-Call Scrubber, which is described to find a phone number on people search sites and data brokers, submits the opt outs, completes the confirmation emails those sites send back, and rechecks on a schedule the user picks. Using it requires the Grok Bot app. The pitch is time saved, since most broker opt outs sit behind separate forms on separate sites.



Musk said Grok Bot now gives each bot its own email address, and that it can detect scam emails. On Thursday he also said SpaceX would make users whole if the bot botches a purchase or leaks a card, then told users to shop away from Amazon after the retailer blocked the agent, as Teslarati reported. The terms of service we reviewed at the time put responsibility for what an agent does on the user.

For Tesla owners, Grok Bot is not just a phone app. Tesla brought Grok Bot into its vehicles on September 22, and we argued earlier this week that the Cybercab’s real advantage may be the errands it runs during a ride. Every Cybercab and the rest of the Model Y Robotaxi fleet has it enabled. The more routine tasks like this one become, the more a rider has reason to hand over something personal in the back seat.

The new Spam-Call Scrubber skill can be downloaded for free and works on sites that honor removal requests, while noting that listings can reappear, and illegal robocallers do not check any registry. Whether Spam-Call Scrubber cuts anyone’s call volume is something the first wave of users will find out, and Musk’s endorsement guarantees that wave is coming.

Tesla’s flying Roadster just revealed something bigger than the car

Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.

The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.

Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.

The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.

The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.


Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.

The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners

Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.

Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.

That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.


Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds

The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.


Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”

There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.
