SpaceX set for third Falcon Heavy launch: here’s how to watch live
SpaceX is T-18 hours to its second Falcon Heavy launch in barely 70 days, set to lift off with the Department of Defense’s Space Test Program-2 (STP-2) rideshare mission no earlier than (NET) 11:30 pm EDT (03:30 UTC), June 24th.
According to SpaceX CEO Elon Musk, STP-2 is without a doubt the company’s “most difficult launch ever”, owing to a multitude of high-stakes performance requirements, US military and NASA oversight, several technical milestones, challenging booster and fairing recoveries, and much, much more. Should SpaceX succeed on all fronts, the company will have taken a massive leap towards being able to offer competitive launch services that can fulfill all of the US government’s many different spaceflight needs.

- SpaceX set for Falcon Heavy triple booster landing, hottest center core reentry yet
- SpaceX ship Mr. Steven renamed, departs for first Falcon Heavy fairing catch attempt in 7 months
Challenges all the way down
Likely the single most challenging aspect of STP-2 is the performance the mission’s Falcon 9 upper stage will have to deliver. SpaceX describes the challenge below:
“[The STP-2 mission] will deliver 24 satellites to space on the DoD’s first-ever SpaceX Falcon Heavy launch. [It] will be among the most challenging launches in SpaceX history, with four separate upper-stage engine burns, three separate deployment orbits, a final propulsive passivation maneuver, and a total mission duration of over six hours.”

According to older USAF documents (STP-2’s original launch target was mid-2015), those numbers could actually rise as high as five separate upper-stage Merlin Vacuum burns and a mission duration of more than 7.5 hours. Given the last-second decision to move Falcon Heavy’s center core recovery from ~40 km offshore to more than 1240 km offshore, it’s fairly likely that five burns and 7.5 hours will be closer to the reality of STP-2. In short, the center core will move from a gentle recovery to what will probably be SpaceX’s hottest and hardest booster recovery ever to transfer as much margin as possible to STP-2’s upper stage.


With regard to that extra spicy reentry, Falcon Heavy center core B1057 – the second Block 5 center core built by SpaceX – is now expected to attempt a landing aboard drone ship Of Course I Still Love You (OCISLY) more than 1240 km (770 mi) off the coast of Florida, potentially smashing the current record of ~970 km (600 mi).
At the same time, fairing recovery vessel GO Ms. Tree (formerly Mr. Steven; renamed due to change in ownership) is steaming hard, heading anywhere from 1400-1600 km into the Atlantic Ocean. Falcon Heavy STP-2 will be the vessel’s first attempted fairing catch since December 3rd, 2018, nearly seven months ago. It will likely crush the previous record for most distant fairing recovery attempt by 50% or more. Whether or not the vessel succeeds and catches its first Falcon fairing(s) ever, it’s exciting to see Ms. Tree (Mr. Steven) out and about for a fairing recovery after months of inactivity.

As always, SpaceX will host an official Falcon Heavy STP-2 livestream, beginning around T-15 minutes and likely lasting at least 1-2 hours as the rocket’s upper stage prepares for a ~7.5-hour orbital marathon.

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.

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.
