On September 17th, a NASA blog post praised the progress SpaceX has made with Crew Dragon’s parachute system, indicating that the company is actually pushing the state of the art forward with improved modeling after dozens of tests.

Both before and after SpaceX completed Crew Dragon’s flawless March 2019 orbital launch debut, both NASA and the agency’s Aerospace Safety Advisory Panel (ASAP) have relentlessly focused on two main concerns: Falcon 9’s COPVs and Crew Dragon’s parachutes. The reasoning behind that focus is logical but may pose some problems.

Assuming that discussion points raised during quarterly ASAP and NASA Advisory Council (NAC) meetings are an accurate external representation of NASA’s internal Commercial Crew Program (CCP) priorities, the space agency has been focused on parachutes and COPVs for years. This is primarily a result of NASA’s notoriously reactive approach to safety: SpaceX suffered two COPV-related Falcon 9 failures in 2015 and 2016 and has experienced an unknown number (likely 1-3) of anomalies during Crew Dragon parachute testing.

As a result, NASA has focused extensively on these two stand-out concerns. To an extent, this is reasonable – if you know things have a tendency to fail, you’re going to want to make sure that they don’t. However, prioritizing reactive safety measures at the cost of proactive safety would be a major risk, akin to getting in a car crash because you didn’t use a turn signal and then prioritizing turn signal use so much that you forget to look both ways before making turns. Sure, you will probably never get in the same crash, but you are raising the risk of new kinds of accidents if you overcorrect your attention distribution.

NASA infamously suffered from this throughout the Space Shuttle program, analyzing known-quantities into oblivion as systematic organizational failures and glaring (but new) design flaws were either ignored or buried until it was far too late. It’s impossible to say if NASA is repeating this apparently deep-seated organizational error with Commercial Crew – only the technical experts at SpaceX and NASA have the data to accurately judge. It can be said with certainty, however, that the space agency (and its advisory panels) completely failed to predict the failure mode(s) that caused an April 20th Crew Dragon explosion that would have almost certainly killed all aboard, all while COPVs and parachutes continue(d) to be the apparent focus.

Pushing the envelope of parachute design

Qualms aside, NASA’s September 17th blog does serve as a unique look into the benefits that the space agency’s prioritization of the obvious – for better or for worse – is producing. According to NASA, the incredibly extensive testing SpaceX has had to do to satisfy agency requirements has lead the company to develop “a better understanding of how to safely design and operate parachute clusters”. SpaceX has reportedly completed 48 distinct parachute tests, of which one or two apparently failed.

In response to the additional testing and analysis NASA required after a recent April 2019 test failure, SpaceX has essentially been forced to push the state of the art of parachute design and modeling to new levels. NASA says that SpaceX has begun to model certain conditions and newfound failure modes in ways that “provide a better understanding of parachute reliability” and have forced NASA to reevaluate its own standards and certification processes. Shown in the video above, SpaceX recently completed a successful second attempt of its failed April 2019 parachute test, a major step towards confirming that the new parachute analysis and design have mitigated prior faults.

Tesla CEO Elon Musk confirmed on Tuesday at the xAI Hackathon that the company would be removing Safety Monitors from Robotaxis in Austin in just three weeks.

This would meet Musk’s timeline from earlier this year, as he has said on several occasions that Tesla Robotaxis would have no supervision in Austin by the end of 2025.

On Tuesday, Musk said:

“Unsupervised is pretty much solved at this point. So there will be Tesla Robotaxis operating in Austin with no one in them. Not even anyone in the passenger seat in about three weeks.”

Musk has made the claim about removing Safety Monitors from Tesla Robotaxi vehicles in Austin three times this year, once in September, once in October, and once in November.

In September, he said:

“Should be no safety driver by end of year.”

On the Q3 Earnings Call in October, he said:

“We are expecting ot have no safety drivers in at least large parts of Austin by the end of this year.”

Finally, in November, he reiterated the timeline in a public statement at the Shareholder Meeting:

“I expect Robotaxis to operate without safety drivers in large parts of Austin this year.”

Currently, Tesla uses Safety Monitors in Austin in the passenger’s seat on local roads. They will sit in the driver’s seat for highway routes. In the Bay Area ride-hailing operation, there is always a Safety Monitor in the driver’s seat.

Three weeks would deliver on the end-of-year promise, cutting it close, beating it by just two days. However, it would be a tremendous leap forward in the Robotaxi program, and would shut the mouths of many skeptics who state the current iteration is no different than having an Uber.

Tesla has also expanded its Robotaxi fleet this year, but the company has not given exact figures. Once it expands its fleet, even more progress will be made in Tesla’s self-driving efforts.

SpaceX reportedly mulling IPO, eyeing largest of all time: report

“I do want to try to figure out some way for Tesla shareholders to participate in SpaceX. I’ve been giving a lot of thought to how to give people access to SpaceX stock,” Musk said.

SpaceX is reportedly mulling an initial public offering, eyeing what would be the largest valuation at the time of availability of all time, a new report from Bloomberg said on Tuesday.

It is one of many reports involving one of Elon Musk’s companies and a massive market move, as this is not the first time we have seen reports of an IPO by SpaceX. Musk himself has also dispelled other reports in the past of a similar nature, including an xAI funding round.

SpaceX and Musk have yet to comment on the report. In the past, untrue reports were promptly replied to by the CEO; this has not yet gained any response, which is a good sign in terms of credibility.

However, he said just a few days ago that stories of this nature are inaccurate:

“There has been a lot of press claiming SpaceX is raising money at $800B, which is not accurate. SpaceX has been cash flow positive for many years and does periodic stock buybacks twice a year to provide liquidity for employees and investors. Valuation increments are a function of progress with Starship and Starlink and securing global direct-to-cell spectrum that greatly increases our addressable market. And one other thing that is arguably most significant by far.”

Musk has discussed a potential IPO for SpaceX in recent months, as the November 6 shareholder meeting, as he commented on the “downsides” of having a public company, like litigation exposure, quarterly reporting pressures, and other inconveniences.

Nevertheless, Musk has also said he wants there to be a way for Tesla shareholders to get in on the action. At the meeting in early November, he said:

“I do want to try to figure out some way for Tesla shareholders to participate in SpaceX. I’ve been giving a lot of thought to how to give people access to SpaceX stock.”

Additionally, he added:

“Maybe at some point., SpaceX should become a public company despite all the downsides of being public.”

Musk has been historically reluctant to take SpaceX public, at times stating it could become a barrier to colonizing Mars. That does not mean it will not happen.

Bloomberg’s report cites multiple unidentified sources who are familiar with the matter. They indicate to the publication that SpaceX wants to go public in mid-to-late 2026, and it wants to raise $30 billion at a valuation of around $1.5 trillion.

This is not the first time SpaceX has discussed an IPO; we reported on it nine years ago. We hope it is true, as the community has spoken for a long time about having access to SpaceX stock. Legendary investor Ron Baron is one of the lucky few to be a SpaceX investor, and said it, along with Tesla, is a “lifetime investment.”

The primary driver of SpaceX’s value is Starlink, the company’s satellite internet service. Starlink contributes 60-70 percent of SpaceX’s revenue, meaning it is the primary value engine. Launch services, like Falcon 9 contracts, and the development of Starship, also play supporting roles.

SpaceX reached an incredible milestone with its Starlink program with a launch last night, as the 3,000th satellite of the year was launched into low Earth orbit.

On Monday, SpaceX also achieved its 32nd flight with a single Falcon 9 rocket from NASA’s Kennedy Space Center.

The mission was Starlink 6-92, and it utilized the Falcon 9 B1067 for the 32nd time this year, the most-used Falcon booster. The flight delivered SpaceX’s 3000th Starlink satellite of the year, a massive achievement.

There were 29 Starlink satellites launched and deployed into LEO during this particular mission:

SpaceX has a current goal of certifying its Falcon boosters for 40 missions apiece, according to Spaceflight Now.

The flight was the 350th orbital launch from the nearby SLC-40, and the 3,000 satellites that have been successfully launched this year continue to contribute to the company’s goal of having 12,000 satellites contributing to global internet coverage.

There are over five million users of Starlink, the latest data shows.

Following the launch and stage separation, the Falcon 9 booster completed its mission with a perfect landing on the ‘Just Read the Instructions’ droneship.

The mission was the 575th overall Falcon 9 launch, highlighting SpaceX’s operational tempo, which continues to be accelerated. The company averages two missions per week, and underscores CEO Elon Musk’s vision of a multi-planetary future, where reliable connectivity is crucial for remote work, education, and emergency response.

As Starlink expands and works toward that elusive and crucial 12,000 satellite goal, missions like 6-92 pave the way for innovations in telecommunications and enable more internet access to people across the globe.

With regulatory approvals in over 100 countries and millions of current subscribers, SpaceX continues to democratize space, proving that reusability is not just feasible, but it’s also revolutionary.
