SpaceX’s first orbital-class Starship prototype was spotted stretching its ‘wings’ on Sunday after completing a successful cryogenic proof test late last week.

While minor relative to almost any other testing milestone, the small step still serves as a reminder that the end goal of Ship 20’s test campaign is a launch on Super Heavy to orbital altitudes and velocities. If that launch goes more or less according to plan, Starship will then attempt to survive an orbital-class reentry for the first time, subjecting it to extreme heat and putting its many thousands of heat shield tiles through their most daunting challenge yet. Dozens of things could (and probably will) go wrong, while almost every system aboard must work perfectly to ensure that Starship makes it through reentry in one piece.

And even if all of that occurs as planned with no major issues, those same systems will still need to hold on for several more minutes to perform a freefall, engine reignition, flip, and landing maneuver that only two other Starship prototypes have completed. As it so happens, one of those crucial systems is Starship’s flaps.

Outfitted with actuators powered by Tesla Model 3/Y motors and a pair of Model S batteries, Starship’s four large ‘flaps’ are only capable of simple flapping motions. While they may look the part, Starship flaps aren’t wings and are specifically designed not to produce lift. Instead, in support of Starship’s unusual descent profile, they act more like the hands and legs of a skydiver (particularly one in a wingsuit), allowing ships to control their pitch, attitude, and roll while freefalling belly-down to the ground. In theory, that allows Starship to gain practically all of the benefit of a structural wing like that on the Space Shuttle but for a far lower mass penalty.

Instead of elegantly slowing down with wings, Starship uses its flaps to create as much drag as possible during descent, slowing down to a terminal velocity around 100 m/s (~225 mph) or less. Using a freefall trajectory and flaps incapable of generating lift does likely come at the cost of “crossrange performance,” referring to how far Starship can travel horizontally in Earth’s atmosphere after reentry. However, significant crossrange performance is almost entirely irrelevant outside of Cold War paranoia like the kind that NASA let influence the Shuttle’s design to an ultimately catastrophic degree. Landing vertically also precludes the need for exceptionally long, expensive runways like those the Shuttle needed.

Aside from allowing it to navigate to a small vertical landing pad (or massive ‘Mechazilla’ catch tower), Starship’s flaps are also important for controlling vehicle orientation and heading during reentry itself. To fill that role, those flaps will have to be able to actuate across their full range of motion during reentry, as Starship’s hypersonic assault against the thin upper atmosphere creates a flood of superheated plasma that wants nothing more to find the gaps in its heat shield. Shuttle engineers had to deal with the same issue, ultimately designing complex seals that would allow the vehicle’s wing and body flaps to actuate during reentry without allowing superheated plasma to leak inside and damage their fragile mechanisms or structure.

Although Starship does have the benefit of relying on steel – not aluminum – for almost all of its structures, it still has to grapple with the same challenges of shielding sensitive electronics, actuators, motors, and more from the reentry onslaught that its heat shield and steel structure are designed to survive.

Half-covered in heat shield tiles, it’s not clear how SpaceX plans to seal off the more sensitive, exposed components of each flap’s actuation mechanism – including motors, cabling, and the hinge itself. Based on what’s visible, Starship’s flaps and the cradle-like ‘aerosurfaces’ they slot into do have very tight tolerances and may rely on some felt-like ceramic wool or TPS blanket to seal the tiny remaining gaps. With small enough gaps, a hypersonic airstream can behave as if there are no gaps at all, suggesting that that might be SpaceX’s preferred approach to sealing Starship flaps.

Up next on Starship S20’s path to launch is the reinstallation of 3-6 Raptor engines (for the third time) ahead of a crucial static fire test campaign that could begin as early as Thursday, October 7th. Likely beginning with 1-3 Raptors, SpaceX will perform an unknown number of static fire tests, ultimately culminating in the first ignition of 4, 5, and 6 engines on any Starship prototype. If all goes well, that testing will also mark the first time Raptor Vacuum has been ignited on a Starship prototype and the first time SpaceX has ignited multiple Raptor variants (sea level and vacuum, in this case) on the same vehicle. Stay tuned for updates on engine installation.

Tesla stock tumbles after earnings, one of its sharpest single-day declines

Published

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.

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.

In a striking revelation that underscores the lucrative crossover between Big Tech and space exploration, Alphabet Inc., Google’s parent company, disclosed a massive $94.1 billion equity stake in SpaceX following the rocket company’s blockbuster initial public offering earlier this year.

The disclosure came in Alphabet’s quarterly filing, marking the first time the long-held private investment has been publicly valued at market prices. Google was an early backer, investing alongside Fidelity in 2015 with roughly $500-900 million at a time when SpaceX was valued around $12 billion.

That bet has delivered extraordinary returns, roughly a hundredfold, transforming a strategic play on satellite internet and launch capabilities into one of Alphabet’s largest assets.

Of the total holding, approximately $80 billion remains subject to short-term post-IPO lockup restrictions, preventing near-term sales. An additional $14.1 billion faces longer-term restrictions, extending into the third quarter of 2027. This structure limits immediate liquidity but protects against market volatility as SpaceX transitions into public trading.

The SpaceX position contributed significantly to gains in Alphabet’s broader investment portfolio, which also includes a major stake in AI leader Anthropic. Combined, these holdings helped drive nearly $100 billion in investment gains during the second quarter, providing a substantial boost to net income amid ongoing AI spending pressures.

Analysts view the disclosure as validation of Alphabet’s venture strategy beyond its core search and cloud businesses. The investment aligns with deeper ties, including reported multi-billion-dollar deals for AI computing capacity on SpaceX infrastructure. As SpaceX advances Starship flights, Starlink expansion, and ambitious Mars goals under Elon Musk, Google’s stake positions it to benefit from the commercialization of space.

For Alphabet, the windfall highlights how patient, forward-looking bets in transformative sectors can yield outsized rewards. While lockups temper short-term impact, the holding cements SpaceX as a cornerstone of Alphabet’s diversified portfolio in an era where aerospace, AI, and connectivity increasingly intersect. Investors will watch closely as restrictions lift and SpaceX’s public performance unfolds.
