SpaceX nails first rocket landing by sea in half a year, sends exoplanet probe beyond the Moon
SpaceX has successfully completed the first drone ship recovery of a Falcon 9 booster in nearly six months, bringing to an end a what will likely be the final drought of by-sea rocket landings in the company’s history.
B1045’s landing was a particularly stunning example of just how far SpaceX has come. By all appearances, the recovery was easily the smoothest yet achieved by the company, with nary a hint of reentry heating visible in the near-flawless live coverage from a camera aboard the booster. Perhaps of even more interest, the landing itself appeared to be exceptionally luxurious, with the booster gently floating down to its final resting perch aboard the drone ship Of Course I Still Love You.
This return-to-landing, so to speak, is SpaceX’s 24th successful Falcon booster recovery in just over three years of true recovery efforts. The last several months have featured an unfamiliar number of intentionally expendable launches, in which SpaceX chose to preclude any attempt at recovery, instead typically gently landing the boosters in the ocean to gather additional flight-test data and to explore the envelope of Falcon 9’s recovery capabilities. In all cases but one (Hispasat 30W-6), these intentionally expended boosters were older, flight-proven versions of the rocket, versions that hadn’t been designed to economically fly more than once or twice.
B1045, however, has just one flight under its belt, and is already pegged for a second launch with CRS-15, giving the booster as few as 50 days to be refurbished and prepped for its second pre-launch static fire (likely the first week of June). This would be an exceptionally fitting case of foreshadowing for SpaceX’s upcoming Block 5 iteration of Falcon 9. If a Block 4 booster can be launched, landed, and refurbished in well under two months, one can only imagine what a Falcon 9 explicitly upgraded for ease of reuse will be capable of.

Over the past six months, SpaceX has aggressively expanded their program of orbital rocket reuse, leaping from just three operational reflights of Falcon 9 boosters in the process’ first half-year (Mar-Oct ’17) to seven operational reflights between the following months of December and April. Today, April 18, the successful launch of NASA’s Transiting Exoplanet Survey Satellite (TESS) marks the final launch of a new Block 4 Falcon 9 booster (B1045) – although we can expect as many as three additional reflights of recovery Block 4 boosters in 2018, all new Falcon 9 boosters from here on out will be Block 5s, a final upgrade to the rocket designed to significantly optimize reliability and reusability. The first Falcon 9 Block 5 is expected to debut sometime in May, currently No Earlier Than (NET) May 4.
Impressively, despite the fairly extensive modifications and upgrades – both for reliability and reusability – included in Falcon 9 Block 5, SpaceX’s Hans Koenigsmann stated that the lengthy test campaign in Texas went well and was in fact “faster than we’ve ever had on new Block upgrades [of Falcon 9].” SpaceX themselves have not yet given a specific date for the debut of Block 5, but Hans did partially confirm recent reports that it is now targeting a debut in “early May” with the launch of Bangabandhu-1. Put simply, so long as things go more or less according to plan, 2018 will in every conceivable way usher in the real future of orbital-class reusable rockets – perhaps enabling the sort of responsive, cheap, and reliable access to space long ago promised by CEO Elon Musk.

TESS will dramatically increase the number of known exoplanets. It will more than double the number found by Kepler. #NASA #TESS #SpaceX #Falcon9

Despite its diminutive size and 350 kg mass, TESS is expected to dramatically expand the number of detected exoplanets in the universe, and is tasked with surveying the remaining 95% of the sky left unscanned after Kepler’s famous mission. Ultimately, conservative estimates from astronomers expect TESS to add thousands of new exoplanets to humanity’s current catalog, with perhaps as many as 10% of those discovered likely to be Earth-sized, and thus potential candidates for the first habitable planets to be observed beyond the cozy bounds of our own Solar System.
To give a sense of just how far electronics and satellite technology have improved in the decade since the Kepler observatory was launched (2009), that 1050kg spacecraft was designed to stare specifically at one small segment of the sky (0.25%), scanning it ceaselessly for exoplanets. Despite complex technical difficulties, Kepler managed to discover nearly 1100 confirmed exoplanets, with more than 3000 additional candidates waiting to be confirmed by other spacecraft or telescopes.

On the other hand, the 350kg TESS, has been designed to sca the entire sky and may well double, triple, or quadruple the number of known exoplanets in the universe. Falcon 9 may undoubtedly be a bit like using a dump truck when a shovel would do, but the tiny size of the payload can be thanked for the exceptionally gentle booster recovery and the equally (relatively) easy refurbishment soon to follow.

Tesla Roadster owners to get “Flying Stunt Mode” and looping track access
Musk says Roadster owners can command the unveiling stunts autonomously, with a Texas looping track.
Elon Musk says owners of the new Tesla Roadster will be able to ask the car to perform the stunts Tesla showed at its unveiling, with the car doing the driving itself. Musk made the comment Saturday in a reply on X to tech blogger Robert Scoble, and he added a promise of a looping track at Tesla’s Texas headquarters.
Scoble had argued that the person in the Roadster is not really driving it. In his description, the driver operates a computer that tells another computer what to do, with steering, braking and acceleration all handled by wire. Musk answered, “True. You will be able to ask the Roadster to perform any of the tricks shown autonomously, as it will be sentient. Also, we will have a wild looping track (crazier even than Hot Wheels) at our Texas HQ where you can test out your Roadster.”
@Scobleizer True.

— Elon Musk (@elonmusk) October 17, 2026
At the October 15 event outside Waco, the car drove up a curved ramp until it was upside down, flew off on cold gas thrusters, flipped and landed. It also hovered over a Cybercab, Cybertruck, Semi, Model Y and Model 3 while moving. As we noted in our breakdown of the three Roadster configurations, Musk said at the event that the car “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. Saturday’s reply adds that the car would run them on its own.
Tesla has described some of the hardware that would make that possible. The Roadster uses steer by wire with a yoke, and its cold gas thrusters rely on electric actuators for small adjustments in flight. A fan system under the car creates suction, which Tesla says is strong enough to hold it upside down, a setup we covered in our look at the Roadster’s fan system and thrusters.
Musk did not say when an autonomous stunt feature might arrive, how it would work, or what he means by sentient. He also gave no size, location or opening date for the Texas track. Production is planned for Giga Texas in 2027 or 2028, and Tesla says the car is not approved for public road use. The Rocket version, the one built to fly, is invite only.
The comment follows a week of Musk teasing the event, including his claim that the demo would be a banger, which we covered before the stream. Tesla reports third quarter earnings on October 21, and shareholders can submit and vote on questions through the Say portal until 4 p.m. EDT on October 20, according to our earnings Q&A preview. A question about autonomous Roadster stunts and the Texas track would be a quick way to get specifics from management.

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.
