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
— Chris G (@ChrisG_SpX) April 15, 2018
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.

SpaceX wants to catch Starship for launch 14, Elon Musk says
Just hours after Starship Flight 13 achieved a successful soft splashdown of its upper stage in the Indian Ocean on July 24, Elon Musk announced an ambitious next step for the company’s next launch of the rocket.
“Unless we discover problems after mission data review, SpaceX will attempt to catch the ship with the tower on [the] next flight,” the SpaceX CEO posted on X on Friday.
That “next flight” is expected to be Flight 14. The plan involves returning the Starship upper stage, commonly called the “ship,” to the Starbase launch tower in Texas and catching it mid-air using the same mechanical “chopsticks” arms that have already proven themselves with the Super Heavy booster.

— Elon Musk (@elonmusk) July 25, 2026
A successful catch would mark the first time an orbital-class upper stage has been recovered this way, advancing SpaceX’s goal of full and rapid reusability for the entire vehicle.
SpaceX has already demonstrated the tower-catch technique multiple times with Super Heavy. The first successful catch came on Flight 5 in October 2024, when Booster 12 was plucked from the sky by the Mechazilla arms. Subsequent flights, including those involving Boosters 14 and 15, repeated the feat. Several of those recovered boosters were later inspected, refurbished, and flown again, proving the system’s viability for quick turnaround.
Traditional reusable rockets, such as SpaceX’s own Falcon 9 or Blue Origin’s New Shepard, land on legs either on land or droneships. Rocket Lab has recovered its small Electron first stages by helicopter, but those are far lighter vehicles.
SpaceX Starship just nailed something it’s never done before
The China Academy of Launch Vehicle Technology (CALT), a subsidiary of the China Aerospace Science and Technology Corp. (CASC), completed a catch of its booster on July 10. They are the only entity besides SpaceX to attempt and complete the feat.
Flight 13 provided encouraging data. The ship executed a controlled reentry, flipped, and soft-landed intact in the ocean after deploying Starlink satellites, offering the first clear post-splashdown views of an undamaged heat shield. The Super Heavy booster, meanwhile, experienced a harder splashdown in the Gulf of Mexico.
Musk has previously stressed that ship catches would only follow multiple successful soft ocean landings to minimize risk of debris over land.
If Flight 14 succeeds, SpaceX would take a major stride toward routine, rapid reuse of both stages—critical for lowering launch costs and supporting ambitious plans for lunar and Mars missions. For now, teams are reviewing the Flight 13 data. Should everything check out, the next Starship flight could deliver one of the most spectacular recoveries in aerospace history.

Tesla to open source Model S and Model X designs and software
In a move echoing its earlier commitment to open innovation, Tesla CEO Elon Musk announced recently that the company plans to make the design and software of its Model S and Model X fully open source.
This follows the same approach Tesla took with its original Roadster, releasing all available design, engineering, and diagnostic materials in November 2023 so that “whatever we have, you now have.”
Just as Tesla made the original Roadster design & software open source, we plan to do the same with Model S & X
— Elon Musk (@elonmusk) July 24, 2026
The Model S, introduced in 2012, was Tesla’s first mass-produced vehicle and a groundbreaking luxury electric sedan. It offered impressive range, rapid acceleration, and over-the-air software updates that redefined expectations for electric cars.
The Model X, launched in 2015, built on that foundation as a high-performance electric SUV notable for its distinctive falcon-wing doors, spacious interior, and advanced safety features. Both models served as flagships that helped establish Tesla as a leader in the EV industry and popularized long-range battery-electric vehicles.
Production of the Model S and Model X was wound down earlier in 2026, with manufacturing ending in the second quarter. Tesla redirected the Fremont factory space previously used for these vehicles toward higher-priority projects, including Optimus humanoid robots and the Cybercab autonomous vehicle.
By the time of Musk’s open-source announcement, custom orders had closed and only remaining inventory was available.
Open-sourcing the designs and software offers several clear advantages. Owners of these aging but still capable vehicles gain better access to technical documentation, diagnostic tools, and software resources, making independent repairs and modifications easier and more affordable.
Independent repair shops and third-party specialists can support the large existing fleet without relying solely on Tesla’s service network. Enthusiasts and engineers can study real-world implementations of Tesla’s battery, powertrain, and software systems, potentially accelerating broader industry progress in electric mobility.
The step aligns with Tesla’s 2014 patent pledge and its overall mission to advance sustainable transport by sharing hard-won knowledge rather than locking it behind proprietary walls.
By releasing these materials now that the models have left production, Tesla ensures continued support for its early adopters while freeing internal resources for future technologies. The open-source release of the original Roadster already enabled simulations, community projects, and deeper technical understanding.
Extending that practice to the Model S and Model X should deliver similar benefits on a larger scale, helping keep these influential vehicles relevant and repairable for years to come

Tesla flexes incredible Robotaxi metric that skeptics will hate
Tesla flexed one incredible Robotaxi metric during the Q2 Earnings Call that skeptics have to hate to hear. The company’s platform has already driven more than 380,000 miles of unsupervised ride-hailing across several states with no notable incidents.
During the company’s Q2 Earnings Call on Wednesday, Vice President of AI, Ashok Elluswamy, said:
“First of all, I’d like to state that the Robotaxi program has been operating extremely well. Especially in terms of safety, the program has had an impeccable safety record. We have driven more than 380,000 miles of unsupervised Robotaxi, now across six cities in two different states. We have had zero notable incidents. Any reports have been of other actors impacting us when we were stationary. I like to emphasize how safe the operation has been so far. Zero notable incidents over 380,000 miles.”
Elluswamy’s claim over Robotaxi miles is a significant milestone for Tesla in the grand scheme, especially considering this is a sizeable number of miles without any incident.
0 notable incidents across over 380,000 miles traveled by Robotaxi
— Tesla (@Tesla) July 22, 2026
Tesla’s self-driving approach is much different than that of other companies. Tesla has maintained that vision is the only thing needed to have a solid and effective self-driving suite. Many self-driving companies utilize things like LiDAR, sensors, and other elements to improve performance, but Elluswamy sent a jab at those who believe it’s needed.
“Historically, the so-called experts have always claimed that you need LiDARs, radars, HD maps, and the entire kitchen sink to drive safely. Here we show that such is not true. You can have safe, comfortable, and affordable autonomy with just cameras. This record should be a huge validation of Tesla’s entire AI approach.”
The feat of accumulating this many miles without any driver behind the wheel is impressive. The thing is, Tesla is also doing this across several different locations, with varying traffic rules, pedestrian levels, weather patterns, and other important factors.
While Tesla is not ready to roll out an unsupervised platform completely, it is a slow but steady indication that the company is well on its way to figuring things out.
The company’s attitude toward expansion is slow, safe, and controlled, and despite this huge milestone, it will still be some time until we see Tesla truly unleash unsupervised rides more aggressively.
