SpaceX CEO Elon Musk kills mini BFR spaceship 12 days after announcing it
Less than two weeks after SpaceX CEO Elon Musk announced that Falcon 9’s “second stage [would] be upgraded…like a mini-BFR Ship” to prove lightweight heatshield and hypersonic control surface technologies, Musk took to Twitter to assert that the mini BFR spaceship project was dead, despite having stated that SpaceX was working to launch that test article into orbit as early as June 2019 just 12 days prior.
From a public perspective, the status of SpaceX’s next-gen rocket program (known as BFR) is effectively up in the air after several cryptic and seemingly contradictory statements from the company’s CEO and chief engineer.
No, we’re just going to accelerate BFR
— Elon Musk (@elonmusk) November 20, 2018
On Nov. 17, Musk tweeted that BFR – last updated in September 2018 alongside a statement that “this is [likely] the the final iteration [of BFR] in terms of broad architectural decisions” – had already been redesigned, going so far as to describe it as a “radical change”. What that radical design change might be is almost entirely unclear, although Musk has now twice stated that the purpose of these changes (and the whiplash-inducing cancellation of the mini-spaceship) is to “accelerate BFR”.
Radical change

As of now, SpaceX appears to have just completed a massive 9-meter diameter composite tank dome in the company’s temporary Port of Los Angeles tent, where a small but growing team of engineers and technicians are working to realize some version of the company’s next-generation rocket. That group has been working in near-silence for the better part of a year and has accepted delivery of and set up a wide range of custom-built tooling for carbon composite fabrication, and has even managed to get that tooling producing massive composite parts that are expected to eventually make up the structure of a spaceship prototype.
That prototype would eventually be shipped to South Texas, where SpaceX is constructing an entirely new facility from scratch to test the design, technology, and operation of the first full-scale BFR spaceship (BFS). As of a few months ago, the plan was to begin those hop tests before the end of 2019, but it’s no longer clear if SpaceX still intends to build a prototype spaceship to conduct hops and high-speed, high-altitude test flights.

Responsibly building giant rockets
One can only hope that the SpaceX employees tasked with bringing an already monumentally difficult idea from concept to reality are learning about these earth-shaking, “radical” decisions and changes through a medium other than Twitter. If those senior engineers and technicians are not extensively forewarned and given some say in these major system-wide decisions, it’s hard to exaggerate the amount of time, effort, and resources potentially being wasted (or at least misdirected).
There is undoubtedly something to be said for getting complex and difficult things as right as possible on the first serious try, especially when the sheer expense of the task at hand might mean that there is only one real chance to try. Still, it’s not particularly encouraging when a three-year-old hardware development program marked by several major design iterations is still experiencing anything close to “radical change”. After multiple years of concerted effort, BFR still appears to be in some sort of design limbo, where a constant and haphazard stream of on-paper changes act as a near-insurmountable hurdle standing in the way of a completed “good enough” blueprint that can begin to be made real.

Ultimately, even if some of the worst-case scenarios described above turn out to be true, there are still many, many reasons to remain positive about SpaceX’s BFR program on the whole. The next-gen rocket’s propulsion system of choice – an advanced engine known as Raptor – is quite mature at this point and may already be nearing initial flight readiness. Regardless of any future changes to BFR’s overall spaceship and booster structures, SpaceX technicians, engineers, and material scientists have likely gained invaluable experience in pursuit of an unprecedented 9-meter diameter rocket built almost entirely out of carbon fiber composites.
Further, it appears that quite a bit of progress has been made over the course of R&D programs related to methane-oxygen RCS thrusters (Falcon uses nitrogen), autogenous tank pressurization with gaseous methane and oxygen (Falcon uses helium), and perhaps even in-situ resource utilization (ISRU) that will be an absolute necessity to generate water, oxygen, and methane that will keep prospective Mars colonists alive and refuel spaceships for the voyage back to Earth.

Tesla is not sparing any expense in ensuring the Cybercab is safe
Images shared by the longtime watcher showed 16 Cybercab prototypes parked near Giga Texas’ dedicated crash test facility.
The Tesla Cybercab could very well be the safest taxi on the road when it is released and deployed for public use. This was, at least, hinted at by the intensive safety tests that Tesla seems to be putting the autonomous two-seater through at its Giga Texas crash test facility.
Intensive crash tests
As per recent images from longtime Giga Texas watcher and drone operator Joe Tegtmeyer, Tesla seems to be very busy crash testing Cybercab units. Images shared by the longtime watcher showed 16 Cybercab prototypes parked near Giga Texas’ dedicated crash test facility just before the holidays.
Tegtmeyer’s aerial photos showed the prototypes clustered outside the factory’s testing building. Some uncovered Cybercabs showed notable damage and one even had its airbags engaged. With Cybercab production expected to start in about 130 days, it appears that Tesla is very busy ensuring that its autonomous two-seater ends up becoming the safest taxi on public roads.
Prioritizing safety
With no human driver controls, the Cybercab demands exceptional active and passive safety systems to protect occupants in any scenario. Considering Tesla’s reputation, it is then understandable that the company seems to be sparing no expense in ensuring that the Cybercab is as safe as possible.
Tesla’s focus on safety was recently highlighted when the Cybertruck achieved a Top Safety Pick+ rating from the Insurance Institute for Highway Safety (IIHS). This was a notable victory for the Cybertruck as critics have long claimed that the vehicle will be one of, if not the, most unsafe truck on the road due to its appearance. The vehicle’s Top Safety Pick+ rating, if any, simply proved that Tesla never neglects to make its cars as safe as possible, and that definitely includes the Cybercab.
