SpaceX sets new Falcon 9 Block 5 reusability milestones for second half of 2019
Speaking at 2019’s Asia-Pacific Satellite (APSAT) Conference, SpaceX Vice President of Commercial Sales Jonathan Hofeller – squeezed into a sea of breaking-news updates – announced that the company plans to launch the same Falcon 9 Block 5 booster for the fifth (or sixth) time by the end of 2019.
Just an add-on at the end of a number of updates focused on SpaceX’s next-generation Starship/Super Heavy rocket, the phrasing reported by SpaceNews.com technically means that there are plans for a Falcon 9 booster to launch for the sixth time in the second half of 2019. The demonstration of such an extreme level of operational reusability barely 18 months after Falcon 9 Block 5’s debut would make it clear that SpaceX’s latest Falcon upgrade has been a resounding success. In line with those positive signs, Hofeller also noted that SpaceX is already starting to transfer the fruits of those labors to its customers by permanently lowering the base price of Falcon 9 launch contracts.

Block 5 off to a spectacular start
First reported on by SpaceNews’ Caleb Henry, one of a few spaceflight journalists able to attend 2019’s Jakarta, Indonesia-based APSAT conference, details about the near-term future of Falcon 9 Block 5 reusability milestones were effectively tacked on at the end of much higher-profile breaking-news tidbits. Although wildly ambitious Starship goals led headlines (stay tuned for Teslarati’s own analysis later this week), the fact remains that ambitious development goals are inherently tenuous and likely to slip, particularly when the subject is large-scale, fully-reusable launch vehicles developed from a nearly blank slate.
What is not up for debate, however, is the fact that SpaceX’s Falcon 9 Block 5 upgrade is already flying routinely and reliably. After a successful debut in May 2018, Block 5 took over all SpaceX launches less than two months later. Since then, a total of 12 freshly-built Block 5 boosters have supported 16 Falcon 9 and 2 Falcon Heavy launches, ten – more than half – of which involved flight-proven boosters. According to official statements made recently by SpaceX executives, Block 5 boosters are expected to support an additional 12-19* launches in the second half of 2019.

Tied directly to claims that the same Falcon 9 Block 5 booster will launch for the fifth or sixth time by the end of 2019, SpaceX already has three Falcon 9 boosters that have each completed a trio of launches, as well as an additional five with either one or two launches under their belts. Pictured at the top of the article, all three thrice-flown Falcon 9 boosters – B1046, B1048, and B1049 – could arguably be selected to become the next pathfinder as SpaceX prepares to put boosters through their fourth launches and beyond.
Rumored to be assigned to Crew Dragon’s in-flight abort (IFA) test prior to a major capsule anomaly on April 20th, B1046 could be off the manifest if SpaceX is confident that said IFA test can still be performed within the next several months. It’s currently unclear if that is a viable option for SpaceX’s Crew Dragon schedule, likely to remain uncertain until the failure investigation is fully completed and any necessary design/hardware/software fixes have been implemented. B1046 completed its third launch in December 2018 (a full six months ago), followed by B1048 in February 2019 and B1049 in May 2019. Although the “unknown territory” aspect of Block 5 reuse milestones is becoming less noteworthy, SpaceX is still likely to treat B104X’s fourth launch as a pathfinder, requiring extra time to dot I’s and cross T’s. With B1046 and B1048 potentially ready to go, that milestone could come any time now.

SpaceX customers already reaping financial benefits
Meanwhile, although certain heads-in-sand competitors continue to act and claim otherwise, SpaceX has reportedly normalized earlier prices for customers flying on flight-proven milestone missions. Speaking at APSAT, SpaceX’s Jonathan Hofeller indicated that that pricing is now the company’s “normal pricing”, pushing Falcon 9’s base price as low as ~$50M according to comments CEO Elon Musk made about a year ago. Two years prior to those comments and about six months prior to SpaceX’s first-ever booster reuse, COO and President Gwynne Shotwell reported that the company was offering discounts of ~10% for customers willing to contract launches on flight-proven Falcon 9 boosters.
In other words, SpaceX has cut Falcon 9’s base launch costs by anywhere from 10-20% over the last three years, a period in which the Falcon 9 V1.2 Full Thrust rocket’s capabilities were also dramatically upgraded from Block 1 (debut: December 2015) through Block 5 (debut: May 2018). Speaking during a press conference focused on Falcon 9 Block 5’s launch debut, CEO Elon Musk estimated that SpaceX has spent more than $1 billion to develop Falcon 9 reusability, while he previously estimated Falcon Heavy’s development costs to be well north of ~$500M. Musk and other execs have previously confirmed that SpaceX means to recoup some or all of that investment, indicating that the current margins of Falcon 9 launch contracts must be extremely favorable.

SpaceX has a healthy commercial manifest and will need to support dozens to hundreds of its own dedicated Starlink launches in order to orbit an operational and profitable constellation.

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.
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.
Ask your @Grok @Bot to remove your phone number from spam call & text lists!

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.
Investor's Corner
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.
Still processing this … the most unreal thing I’ve seen. https://t.co/HtEuvnkZjY

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.
