SpaceX talks Moon mission as strategic stepping stone for Mars colony
Josh Brost, Senior Director of SpaceX’s Government Business Development was in attendance at a civil spaceflight conference in Washington D.C. yesterday, January 18, and provided a number of interesting details about SpaceX’s upcoming activities in 2018. Perhaps most intriguingly, he reiterated SpaceX’s interest in enabling exploration of the Moon and Mars, while also clarifying that the upcoming Falcon 9 upgrade will be the last major change to the vehicle for the indefinite future.
Although the audience may have been more focused on SpaceX’s potential lunar prospects, Brost provided a vision similar to CEO Elon Musk’s common-knowledge goal of Martian (and interplanetary) colonization. This lunar focus was in part evidenced by a pointed question from an audience member that triggered Brost’s subsequent suggestion that the Moon could be a more logical starting place for the company as it ramps up its deep space efforts and gradually slips beyond Earth orbit. This strategic and calculated extension of the aspirations of the launch company’s famous founder is a rational attempt to position SpaceX in ways that allow the company to derive as much value as possible from the US government’s recently revived interest in returning the US and its astronauts to the Moon.

To a large extent, his comments mesh with the vision Elon Musk reiterated at 2017’s September IAC.
SpaceX’s next-generation heavy-lift rocket and spaceship (BFR and BFS) are being designed to carry 150 metric tons into low Earth orbit while still recovering both the first and second stages, and will be purpose-built for rapid and complete reusability. BFR and BFS are also being intentionally designed to be relatively destination-agnostic. In other words, BFS will be capable of transporting cargo and eventually crew to a number of destinations in the solar system, be it the Moon, Mars, or beyond. The outer planets are almost certainly off limits for crew due to the sheer length of any journey beyond the orbit of Mars, but BFR, as it was discussed last year, would be capable of transporting unprecedented amounts of cargo almost anywhere in the solar system. Reusability is, of course, paramount to SpaceX’s operational intent with BFR/BFS; unless a very lucrative offer is made, it is highly unlikely that SpaceX will even consider expendable missions, thus partially limiting what the next-gen vehicle will be capable of.
Still, it will be an incredibly capable rocket even with full reusability. Add in the potential promise of mature in-situ resource utilization (ISRU), more simply the production of methane and oxygen propellant at the destination, and it will open a hundred entirely new worlds to serious scientific, exploratory, and economic prospecting throughout the solar system.
What’s next?
The question, then, is “when?” While Brost did not specifically provide any sort of timeline for BFR, aside from a brief statement on its readiness in “a few years,” he did describe in some detail the imminent end of serious Falcon 9 upgrades. A continual stream of upgrades and modifications has been one of the only real constants with SpaceX’s Falcon 9 rocket: the original Falcon 9 is in almost every respect a completely different rocket when compared to the Falcon 9 Full Thrust (FT/1.2) of the present. However, one final leap is expected for Falcon 9, this time almost exclusively intended to improve the vehicle’s reliability and reusability as SpaceX rapidly approaches its first flights of Crew Dragon and dreams of rapid and repeated booster reuse.
While it was a small detail in an obscure sentence of one of several hour-long discussions, Brost specifically stated this:
Brost: with Block 5, goal it to lock down the design and fly the vehicle at very high flight rates. Innovation will focus on designing and testing BFR.

This is arguably the most exciting tidbit provided to us by SpaceX. While it was undeniably vague and rather less than crystal-clear, it can be interpreted as something like this: once Block 5 has been introduced and begun to fly and refly both regularly and successfully, the vast majority of SpaceX’s launch vehicle development expertise will begin to focus intensely on the development and testing of BFR and BFS.
Statements from just last week made by SpaceX President Gwynne Shotwell strengthen this intuitive leap considerably, because BFR and BFS are liable to require a considerable amount of attention as they proceed through design maturation and eventually begin physical hardware testing in Texas.
Shotwell’s comments implied that SpaceX’s Boca Chica launch facilities, currently under construction, would be ready to support “vehicle tests” as early as late 2018/early 2019. Comments from earlier in 2017 indicate that SpaceX (and Shotwell) perceive Boca Chica as a near-perfect location for BFR launches (and thus BFR testing, as well). Finally, Brost’s implication that SpaceX’s exceptional team of brilliant and innovative launch vehicle engineers would be refocused on BFR soon after Block 5 was stable also meshes with this rough timeline. If Falcon 9 Block 5 does indeed debut within the “next few months” as Brost stated, it will have likely reached some level of design and operational maturity by the end of 2018, assuming SpaceX’s expected launch cadence.

As of right now, SpaceX is already looking at a very busy February, and currently has as many as three commercial launches scheduled within a period of maybe three weeks (GovSat-1, PAZ, and Hispasat), maybe even four if Falcon Heavy completes its first static fire later this weekend. Musk estimated that SpaceX would complete 30 missions in 2018, and a cadence anywhere near three launches per month (let alone four) would easily push SpaceX past that goal and provide the company dozens of opportunities to test, launch, recover, and relaunch their new Block 5 version of Falcon 9. As such, while BFR is probably not going to reach fully integrated hardware development or testing in 2018, it is certainly a distinct possibility, and 2019 is far more promising for the company’s interplanetary aspirations.
For now, SpaceX’s 2018 focus is quite explicitly centered on ensuring the reliability of its Crew Dragon – set to debut NET August 2018 – and Falcon 9 as it strives to complete the development of both vehicles. Up next on the company’s busy schedule is another attempt at Falcon Heavy’s inaugural static fire on Saturday afternoon, as well as the flight-proven launch of GovSat-1/SES-16, currently NET January 30.

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!
— Elon Musk (@elonmusk) October 15, 2026
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.
