SpaceX indefinitely delays second Falcon 9 launch in two weeks
For the second time in less than two weeks, SpaceX has indefinitely delayed a Falcon 9 launch after discovering apparent issues with the rocket less than a day before liftoff.
Japanese startup ispace’s misfortune also marks the eighth time in less than two months that SpaceX has delayed or aborted a Falcon 9 launch for unspecified technical reasons less than 24 hours before liftoff. The streak of delays is unusual after 12 months of record-breaking execution, over the course of which SpaceX has successfully completed 60 orbital launches with just a handful of last-minute technical delays.

The number of last-day delays and Falcon 9 launch aborts has abruptly skyrocketed in recent months, possibly indicating that a single problem or change is at least partially responsible for the trend. The streak began in early October and has continued through the end of November, resulting in eight delays in two months, with impacts ranging from minutes to days or even weeks. In all but one instance, SpaceX’s only explanation was a need for more time for “data review” or “checkouts” of the rocket, its payload, or both.
SpaceX consistently announces launch delays on Twitter, making it possible to collate when the company has stated it was “standing down” from a launch attempt or “now targeting” a later launch date for technical reasons. In the 18+ months between March 2021 and October 2022, SpaceX announced only three technical delays after publicly scheduling a launch (one last-second abort and two minor “additional checkouts” delays). Adding to the oddity, SpaceX reported at least 15 similar delays between January 2020 and March 2021.
A decrease in the frequency of technical issues is a generally expected outcome of a competent organization gaining experience with the operation of a complex, new system (like a launch vehicle). By all appearances, that’s the pattern SpaceX was following: a drastic drop in the number of technical launch aborts even as the pace of Falcon 9 launches soared to new heights. But within the last two months, the frequency of technical delays has skyrocketed from close to zero to higher than any point in recent SpaceX history.
Without context, it’s impossible to say if there is an invisible thread connecting the recent string of delays. There are many possible explanations, including workforce fatigue, management changes, policy changes, and factory issues. It’s even possible that the seemingly sudden onset was caused by an intentional change of risk posture: for example, increasing sensitivity to off-nominal signals that had been observed before but were discounted enough to avoid launch delays.
As part of its effort to continually improve existing systems and processes, SpaceX could have changed things too much or removed one too many steps. While unlikely, it’s also possible that the recent uptick in delays is merely a coincidence. Regardless, if the trend continues, it will be difficult for SpaceX to increase its launch cadence any further – particularly toward CEO Elon Musk’s stated goal of 100 launches in 2023. Delays also increase launch costs and disrupt customer plans, incentivizing a return to smoother operations as quickly as possible.
Most concerning is a recent pair of unrelated launches that have become indefinitely delayed. Starlink 2-4, first scheduled to launch on November 18th, has yet to receive a new launch date after SpaceX apparently discovered problems after a Falcon 9 static fire test on November 17th. Less than two weeks later, SpaceX has indefinitely delayed a second Falcon 9 launch – Japanese startup ispace’s first Moon landing attempt – “after further inspections of the launch vehicle and data review.”
Ultimately, launch delays are a fundamental part of spaceflight, and it’s better to keep a rocket on the ground when there is any uncertainty about its readiness for flight. Nonetheless, big changes in the frequency of delays are still noteworthy, especially when SpaceX itself does not typically explain the cause of delays for non-NASA missions.
SpaceX has several more Falcon 9 launches firmly scheduled in December. It remains to be seen how exactly the indefinite delays of Starlink 2-4 and HAKUTO-R will impact those upcoming launches. Starlink 4-37, for example, was scheduled to launch from the same pad as HAKUTO-R as early as December 6th, but that date will slip for every day HAKUTO-R is delayed. A SpaceX ship tasked with recovering HAKUTO-R’s Falcon 9 fairing appears to be heading back to port, indicating a delay of at least two or three days.

SpaceX wins its first MARS contract but it comes with a catch
NASA awarded SpaceX a $175 million Mars rover contract while the White House proposes cutting the mission.
NASA just signed a $175.7 million contract with SpaceX to launch a Mars rover that the White House is simultaneously trying to defund. The contract, awarded on April 16, 2026, tasks SpaceX’s Falcon Heavy with launching the European Space Agency’s (ESA) Rosalind Franklin rover from Kennedy Space Center in Florida, no earlier than late 2028. It would mark the first time SpaceX has ever sent a payload to Mars.
Under NASA’s Rosalind Franklin Support and Augmentation project, known as ROSA, the agency is providing braking engines for the rover’s descent stage, radioisotope heater units that use decaying plutonium to keep the rover warm on the Martian surface, additional electronics, and a mass spectrometer instrument, as noted by SpaceNews.
Those nuclear heating units are the reason an American rocket was required at all. U.S. export controls on radioisotope technology mean any payload carrying them must launch on a domestic vehicle, which narrowed the field to SpaceX and United Launch Alliance. Falcon Heavy’s pricing made it the practical choice.
SpaceX is quietly becoming the U.S. Military’s only reliable rocket
Falcon Heavy debuted in February 2018 and has 11 launches to its record. The rocket has not flown since October 2024, when it sent NASA’s Europa Clipper toward Jupiter. The three-core design, built from modified Falcon 9 first stages, gives it the lift capacity needed for deep space planetary missions that a single Falcon 9 cannot reach.
The Rosalind Franklin rover has been sitting in storage in Europe for years. It was originally due to launch in 2022 as a joint mission with Russia, but Russia’s invasion of Ukraine ended that partnership, leaving the rover built but stranded without a launch vehicle or landing hardware. NASA stepped back in through a 2024 agreement with ESA to rescue the mission. The rover is designed to drill up to two meters below the Martian surface in search of evidence of past life, a science objective no previous mission has attempted at that depth.
The contradiction at the center of this story is hard to ignore. The White House’s fiscal year 2027 budget proposal included no funding for ROSA and did not mention the mission at all in the detailed congressional justification document released April 3.
Musk has long argued that reaching Mars is not optional. “We don’t want to be one of those single planet species, we want to be a multi-planet species.” Whether this particular mission survives Washington’s budget fight, the Falcon Heavy contract means SpaceX is now formally on record as the rocket that could get humanity’s next Mars science mission off the ground.
The timing of this contract carries extra weight given that SpaceX filed confidentially with the SEC in early April and is targeting an IPO roadshow in the week of June 8. It would be the largest public offering in history.
Tesla (NASDAQ: TSLA) is set to hold its Earnings Call for the first quarter of 2026 on Wednesday, and there are a lot of interesting things that are swirling around in terms of speculation from investors.
With the company’s executives, including CEO Elon Musk, answering a handful of questions that investors submit through the Say platform, fans want to know a lot of things about a lot of things.
These five questions come from Retail Investors, who are normal, everyday shareholders:
- When will we have the Optimus v3 reveal? When will Optimus production start, since we ended the Model S and Model X production earlier than mid-year? What’s the expected Optimus production rate exiting this year? What are the initial targeted skills?
- What milestones are you targeting for unsupervised FSD and Robotaxi expansion beyond Austin this year, and how will that drive recurring revenue?
- How will Hardware 3 cars reach Unsupervised Full Self-Driving?
- When do you expect Unsupervised Full Self-Driving to reach customer cars?
- When will Robotaxi expand past its current limited rollout?
Additionally, these are currently the three questions that are slated to be answered by Institutional Firms, which also answer a handful of questions during the call:
- Now that FSD has been approved in the Netherlands and is expected to launch across Europe this summer, can you discuss your Robotaxi strategy for the region?
- What enabled you to finish the AI5 tapeout early and were there any changes to the original vision? Last week, Elon said AI5 will go into Optimus and the Supercomputer, but one month ago said it would go into the Robotaxi. Has AI5 been dropped from the vehicle roadmap?
- Given the recent NHTSA incident filings, can you update us on the Robotaxi safety data? If safety validation remains the primary bottleneck, why not deploy thousands of vehicles to accelerate the removal of the safety driver?
The questions range through every current Tesla project, including FSD expansion and Optimus. However, many of the answers we will get will likely be repetitive answers we’ve heard in the past.
This is especially pertinent when the questions about when Unsupervised FSD will reach customer cars: we know Musk will say that it will happen this year. Is Tesla capable of that? Maybe. But a more transparent answer that is more revealing of a true timeline would be appreciated.
Hardware 3 owners are anxiously awaiting the arrival of FSD v14 Lite, which was promised to them last year for a release sometime this year.
The Earnings Call is set to take place on Wednesday at market close.

Elon Musk reveals shocking Tesla Optimus patent detail
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
Elon Musk revealed a shocking detail on the Tesla Optimus patent that was revealed last week. Despite it being made public for the first time, Musk said the company has already moved on from the design, an incredible truth about the development of new technology: things move fast.
Musk dropped a bombshell about the Tesla Optimus humanoid robot hand patent that was released last week. Musk, candidly replying to a post late at night on X, revealed that what is a new technology to many fans and insiders is actually old news to those developing the tech directly.
“We already changed the design,” Musk said. “This one didn’t actually work.”
We already changed the design. This one didn’t actually work.

Patents, after all, are often viewed as blueprints for future products. Yet Musk revealed that the rolling contact mechanism—intended to provide smooth, low-friction articulation in the fingers—had already been scrapped after real-world testing exposed its shortcomings.
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
The hand has been one of the biggest challenges for Tesla engineers since Optimus development started years ago. Musk has said that there is not enough recognition for how incredible and useful the human hand is, and designing one for a humanoid robot has been the biggest challenge of all.
Tesla is stumped on how to engineer this Optimus part, but they’re close
This moment underscores the persistent engineering hurdles in achieving reliable humanoid hand dexterity. Human fingers are marvels of evolution: 27 bones, intricate tendons, ligaments, and a network of sensors working in perfect harmony. Replicating that in metal and silicon is extraordinarily difficult.
Rolling contacts promised reduced wear and precise motion, but testing likely revealed issues with durability under repeated stress, grip stability on varied surfaces, or the micro-precision needed for fine motor skills.
These aren’t minor tweaks, but instead they represent fundamental challenges that have plagued robotics teams for decades. Even advanced competitors struggle here—hands remain the Achilles’ heel of most humanoids because the margin for error is razor-thin.
A fraction of a millimeter off, and a robot drops a glass or fails to button a shirt.
What makes Musk’s reply remarkable is how it signals Tesla’s direct communication style on prototype limitations. While many companies guard failures behind glossy marketing and vague timelines, Tesla openly shares setbacks.
Musk was forthcoming about the failure of this recent design. This transparency builds trust with investors, engineers, and fans. It shows Tesla treats Optimus development like true science: rapid iteration, rigorous testing, and zero tolerance for hype that doesn’t match reality.
The disclosure from Musk also highlights Tesla’s blistering pace of development. By the time the patents are published, which is often over a year after the initial filing, the technology has already evolved.
Optimus is far from a static product, and it’s a living project advancing weekly.
In the high-stakes race for general-purpose robots, Tesla’s approach stands out. Admitting a finger-joint design “didn’t actually work” isn’t a weakness—it’s confidence.
True innovation demands confronting failure head-on, and Musk just reminded the world that Optimus is being engineered that way. The next version of those hands is already in testing, and it will be better because Tesla isn’t afraid to say what didn’t work.
