SpaceX’s BFR and Raptor deemed “science-fiction” by French space agency manager
Speaking in a September 7th interview with French newspaper Courrier International, Dr. Francis Rocard – director of French space agency CNES’ solar system exploration program – had little good to say about SpaceX and CEO Elon Musk’s long-term ambitions in space, going so far as to question the CEO’s driving ethics and label the company’s next-generation rocket and propulsion system “science-fiction”.

Pehaps best known for its involvement in interplanetary space exploration missions like Rosetta and European launch provider Arianespace, CNES is providing a bit less than 25% of the $3.8 billion ESA is spending to develop the Ariane 6 rocket, as well as another $700m for the construction of a new launch pad and support facilities at the space agency’s French Guiana spaceport.
ArianeGroup, a public-private partnership and company, plans to begin replacing its highly successful Ariane 5 rocket with Ariane 6 as early as 2020 and is providing roughly $475 million of its own money to develop that launch vehicle. Ariane 5, which just completed its 100th successful launch on September 25th, costs between $165m and $220m (2016) per launch and is fully expendable, while Ariane 6 – also fully expendable – is targeting a slightly more practical cost between $100m and $130m per flight.

Differences between Ariane 5 and Ariane 6 are exceedingly minor, with the majority of differences found in the cost of each rocket. The end result for customers is essentially the exact same performance of Ariane 5 (or significantly worse) for at most a 40% discount. Ariane 6 will have light (2 solid rocket boosters) and heavy (4 SRBs) variants, and the light variant (known as Ariane 62) is expected to cost no more than 20% less than its heavy cousin while offering considerably less than half the performance.
This poses a major issue for ArianeGroup, as its current Ariane 5 only marginally functions as a commercial rocket thanks to an extensive reliance on dual-satellite launches, in which two different payloads are manifested on the same rocket in order to halve the cost each customer must pay. According to Arianespace, the best possible price a customer might wind up paying for one of Ariane 5’s two slots is ~$60m, essentially the same as the base price for a dedicated Falcon 9 launch. The problem, however, lies in the reality that Ariane 62 will be effectively incapable of performing the same dual-manifest launches but end up costing significantly more for a dedicated launch than the $60m-$100m Ariane 5 customers currently expect.

Ariane 64, at most a 40% cheaper replacement for Ariane 5, doesn’t even have a tentative launch debut date set, while Ariane 62 is pencilled in for a 2020 debut with several more launches soon after, potentially ramping up to a dozen missions per year in the mid-2020s. Rocard, while not directly involved in CNES’ own tenative work with reusable rocket experiments or its relationship with Ariane rockets, placed himself in an inopportune position by so bluntly dismissed and demeaning the near to long-term ambitions of SpaceX.
Not only are BFR and Raptor quite literally real enough to touch, but SpaceX’s Falcon 9 Block 5 is beginning to ramp up launch and reuse activities, placing the launch upstart in a position where the long-term survival – let alone success – of ArianeGroup and its Ariane 6 rockets seems no less likely than SpaceX’s realization of its Mars aspirations in the 2020s and 2030s. May the best rockets win.

SpaceX Starship Flight 13 faces wrath of the Texas skies
SpaceX pushed Starship Flight 13 to Friday, blaming weather instead of the previous engine issues.
SpaceX called off Thursday’s launch attempt of Starship Flight 13, pushing the mission to Friday because of weather tied to Tropical Storm Bertha. The company confirmed the delay on X, noting “Now targeting Friday, July 24 for Starship’s thirteenth flight test, due to weather. A key objective for the flight test is to get clear imagery from the ground of Starship’s heatshield as it flies at a higher dynamic pressure during ascent, which won’t be possible with today’s weather conditions.”
This is the second delay for Flight 13 in two weeks. SpaceX first tried to launch the mission on July 16, but the countdown ended in an automated abort at T-0 when four of Super Heavy Booster 20’s 33 Raptor engines failed to ignite. Musk said at the time that two Raptors would need to be removed and replaced, as Teslarati reported. The company spent the following week destacking Ship 40 and Booster 20, swapping engines, and running leak checks before restacking the vehicle on Pad 2 Wednesday night, according to Spaceflight Now’s live coverage.
Unlike the engine problem, Thursday’s delay has nothing to do with the hardware. SpaceX wants clean footage of Starship’s heat shield captured from the ground as the vehicle flies through max dynamic pressure, something the storm’s cloud cover over South Texas would not allow. The company said visibility should improve for Friday’s attempt, with the same 90 minute window opening at 5:45 p.m. CT.
Flight 13 will be the second outing for the V3 versions of Starship and Super Heavy, following their debut on Flight 12 in May. The mission carries 20 production Starlink V3 satellites, the first time SpaceX has flown operational satellites rather than mass simulators on Starship. Six of those satellites are fitted with cameras to inspect the heat shield from a different angle during ascent, giving engineers a second data source beyond the ground imagery the weather is currently blocking.
Booster 20 will attempt a boostback burn and a splashdown landing burn in the Gulf of America, while Ship 40 follows a suborbital trajectory toward a landing in the Indian Ocean. The flight plan largely mirrors Flight 12, though the booster will run a more aggressive ascent burn after max Q this time, and the ship’s heat shield includes load sensing tiles meant to measure stress at the higher dynamic pressure SpaceX is targeting.
If Friday’s attempt succeeds, Flight 13 could be the last suborbital test in the program. SpaceX is already looking to push for an orbital flight on Flight 14.

Tesla stock tumbles after earnings, one of its sharpest single-day declines
Tesla stock (NASDAQ: TSLA) endured one of its sharpest single-day declines in years on July 23, tumbling approximately 14.5 percent and closing near $320 after opening the session around $374. The drop erased more than $140 billion in market value amid heavy trading volume and left the shares at multi-week lows.
The sell-off followed the company’s second-quarter 2026 results, released the previous evening. Tesla reported record revenue of $28.2 billion, up 26 percent year over year, driven by a Q2-record 480,126 vehicle deliveries. Energy storage deployments also rose strongly.
Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue
Yet profitability disappointed sharply. Operating income fell 57 percent to $398 million, compressing the operating margin to just 1.4 percent. Non-GAAP earnings per share came in at $0.33, well below the roughly $0.53 analysts had expected. Free cash flow turned negative by $1.1 billion as capital expenditures surged 142 percent to $5.8 billion, largely tied to accelerated spending on artificial intelligence, robotics, and autonomous systems.
The losses on capex were expected, as Tesla said it would be spending heavily in 2026.
Investors also reacted to lingering uncertainty surrounding key product timelines. During the Earnings Call, management reiterated ambitions for Robotaxi deployment and the Optimus humanoid robot, but offered limited new concrete milestones, renewing questions about execution pace that have long accompanied Tesla’s ambitious roadmap.
The magnitude of the decline places it among Tesla’s more severe one-day percentage losses since its 2010 initial public offering. Historically, the two largest single-day drops (split-adjusted) remain September 8, 2020, when shares fell 21.1 percent amid broader market volatility and valuation concerns, and January 13, 2012, with a 19.3 percent plunge during the company’s early growth struggles.
Other notable declines include an 18.6 percent drop on March 16, 2020, at the onset of pandemic-related market turmoil. Thursday’s move ranks roughly ninth on the all-time list but stands out as the steepest in more than a year.
Despite the short-term pain, Tesla’s long-term trajectory has repeatedly recovered from such volatility. The latest results underscore both the strength of its core automotive and energy businesses and the near-term costs of heavy investment in next-generation technologies.

Elon Musk is not happy about this Tesla Full Self-Driving approval delay
Elon Musk clapped back at France’s decision to withhold the approval for Tesla’s Full Self-Driving (FSD) Supervised system, projecting a clear and blunt message to French Transport Minister Phillippe Tabarot, after he publicly rejected the technology in its current form.
Tabarot outlines several concerns with Tesla Full Self-Driving in a detailed video statement, where he said, “The safety trade-offs are not yet sufficient to authorize it as it currently stands,” he said. He emphasized that FSD is not a true self-driving system and that the driver remains fully responsible.
Key issues Tabarot also brought up included allowing speeding when surrounding traffic exceeds limits and what he believes are insufficient guarantees of driver attention during complex urban maneuvers such as lane changes, intersections, and roundabouts.
Delaying the approval of FSD in France will cost lives
— Elon Musk (@elonmusk) July 22, 2026
While acknowledging technological progress and France’s support for autonomous innovation, Tabarot stressed that deployment must prioritize road safety. He noted ongoing technical discussions with Tesla, the Netherlands, and other European partners, with further ecosystem meetings planned for the fall.
Musk’s rebuke highlights the human cost of regulatory caution. Tesla’s latest safety reports provide compelling data supporting accelerated adoption. In the most recent 12-month period, vehicles using FSD (Supervised) recorded one major collision per approximately 5.1 million miles driven, dramatically better than the U.S. national average of one crash per 698,000 miles.
Even Tesla vehicles driven manually with active safety features outperform the average by a wide margin. These figures come from billions of real-world miles of telemetry, showing FSD vehicles involved in far fewer incidents than both manual Teslas and the broader U.S. fleet.
Critics argue Tesla’s comparisons require careful scrutiny regarding reporting thresholds and fleet demographics, yet the data consistently positions FSD as a potential lifesaver. With road fatalities remaining a leading cause of death worldwide, Musk contends that proven safer technology should not face prolonged bureaucratic hurdles.
France’s measured approach reflects the broader European regulatory caution, which many, especially Musk, have been critical of in the past. However, as autonomous systems from Tesla and competitors like Waymo demonstrate superior safety in independent studies, pressure is mounting for harmonized approvals.
Musk’s warning carries the belief that every month of delay may equate to avoidable tragedies on European roads.
