First living tissue 3D printed in space aboard International Space Station
Using the “Organaut”, a 3D bioprinter designed for microgravity, Russia has become the first country to print living tissue in space. After a December 3rd cargo delivery to the International Space Station (ISS), cosmonaut Oleg Kononenko completed an experiment with the machine in the Russian sector of the station, successfully producing human cartilage tissue and a rodent thyroid gland. The Organaut was designed via a collaboration with the printer’s maker, 3D Bioprinting Solutions, and Russia’s national space agency, Roscosmos. The United States also has its own bioprinting mission scheduled for the first half of 2019, joining in the march to develop biological solutions for problems that space is well suited to solve.
A 3D bioprinter operates by creating one layer at a time of specified tissue or stem cell material arranged as needed to grow and form as biologically programmed to do. As summarized by Aryeh Batt, the CEO of Precise Bio, a company dedicated to 3D printed bioproducts for human eyes, “Essentially, the biology does the work, but you have to put them in the correct environment to make it happen.” In the case of Organaut, an internal robotic mechanism drips living cell fabric layers from an automatic syringe. When living tissue is bioprinted under Earth’s gravity, the artificial cells grow in a flatter structure than their natural state in the human body. In microgravity, however, they form a shape closer to their normal dimensions.
Along with demonstrating the growth advantages of microgravity, Organaut’s tissue samples will provide the ability to study the effect of radiation on the body. “We will look at how the constructs came together, and how they behaved,” confirmed Usef Hesuani, head of laboratory projects and a managing partner of 3D Bioprinting Solutions in a recent press conference. The original Organaut printer was aboard the Soyuz MS-10 spacecraft which experienced an launch failure on October 11, 2018, forcing the U.S. and Russian crew to make an emergency landing. A second one was quickly put together for the subsequent mission.
The parent company of 3D Bioprinting Solutions is INVITRO, the largest private medical company in Russia. Founded in 1995 by Aleksandr Ostrovsky, it has 8 laboratories and over 1000 medical offices in eastern Europe, but is primarily based in Skolkovo, a high technology business area in Moscow. Bioprinting Solutions made headlines in 2015 when it printed and transplanted a functioning mouse thyroid gland. The experiment performed aboard the ISS with Organaut was a modified version of their prior work.
Unlike NASA, Roscosmos does not generally partner with private companies for its research endeavors. In an effort to inspire Russian students to enter STEM fields within their country, the agency sought to spotlight the developing bioprinting industry by using the Organaut. The successful partnership with 3D Bioprinting Solutions has now motivated the agency to continue partnering with private companies in the future. The company itself also sees advantages to collaborations of its own with other Skolkova-area manufacturers. “We have companies that are making satellite platforms…it is possible to conduct a similar experiment amid microgravity on small spacecraft [like satellites]…smaller and cheaper,” noted Ivan Kosenkov, 3D Bioprinting Solutions’ project manager.
Organaut’s printed tissues were returned to Earth with the Soyuz MS-09 spacecraft on December 20th, and the results of the experiment are expected to be published at the end of January 2019. In February, NASA plans to send a bioprinter capable of producing beating heart tissue to the ISS. Named the 3D BioFabrication Facility (BFF), the machine was developed through a partnership with two companies well-established in 3D printing and on-orbit hardware, nScrypt and Techshot. Since the thickness of heart tissue is difficult to build under gravity without structural assistance that could impede functionality, the companies developed the BFF with the hypothesis that microgravity would overcome this limitation. Thus far, the concept has been proven during parabolic flight tests, i.e., aboard the “Vomit Comet” airplane that performs multiple parabolic maneuvers in an airliner to create 20-30 seconds of weightlessness each.
Tesla just gave what is perhaps its biggest signal yet that the launch of the Cybercab, its autonomous ride-hailing-geared car, is imminent.
The Cybercab has been spotted outside of Gigafactory Texas in massive numbers over the past few days, with hundreds of units being stored on property just days after the vehicle received a Certificate of Conformity from the EPA.
Today, things were a bit different.
Cybercabs spotted on Giga Texas property today had an addition: a Cybercab decal on the side, reminiscent of the “Robotaxi” ones that were placed on Model Ys just as the company launched its ride-sharing platform about a year ago.
Giga Texas drone operator Joe Tegtmeyer noticed the change today:

Tesla could be signaling that the Cybercab is preparing to enter the Robotaxi fleet in the coming weeks or months with this move. It seems more symbolic than anything; Tesla is ready to throw Cybercabs in the ride-hailing platform just as it did with Model Ys last year.
The addition of the Certificate of Conformity awarded to the Cybercab is another major factor working to Tesla’s advantage. The company now has permission from the EPA to allow the vehicle to operate on public roads and enter the chain of commerce. It’s officially street legal.
Tesla Cybercab specs revealed: range, curb weight, range ratings, and more
The big question that remains is whether Tesla will be able to operate the car without a safety monitor, especially considering it plans to put the car out there without a steering wheel or pedals. With the Cybercab only having a seating capacity of two, it is hard to believe Tesla will even consider putting a Safety Monitor in the car.
It did recently self-certify as Level 4 and has the ability to operate driverless vehicles in the State of Texas under a law that took effect on May 28. You can read more about that here:
Tesla’s Robotaxi dreams just took a massive step toward reality
We’d imagine Cybercabs will be on the roads as soon as July, but August will likely be a better estimate of when the car will be entered into the Cybercab fleet. It all depends at where Tesla is, as they’ve truly prioritized safety with the rollout of the Robotaxi platform.
Elon Musk has publicly questioned Moody’s credit assessments following the rating agency’s decision to assign SpaceX a Baa1 investment-grade rating, two notches above Tesla’s Baa3. The comments came amid discussions comparing the two companies’ financial profiles.
SpaceX earned its first-time Baa1 rating with a stable outlook from Moody’s. The agency highlighted the company’s leadership in orbital launches, the growing recurring revenue from its Starlink satellite network, strong vertical integration, U.S. government contracts, and emerging opportunities in AI infrastructure.
These factors were cited as supporting robust cash flows, margin expansion, and financial flexibility.
Musk responded directly: “Tesla’s credit rating is ridiculously low tbh,” and added, “Yeah, makes no sense. Tesla has over $40B in cash, no debt, and is consistently profitable!” His remarks underscored Tesla’s balance sheet strength and profitability at a time when many traditional automakers continue to report losses in the shift to electric vehicles.
Yeah, makes no sense.
Tesla has over $40B in cash, no debt and is consistently profitable!

Tesla maintains a leading position in the global EV market, with diversification into energy and storage, battery technology, and robotics through projects like Optimus. Recent financial updates show the company generated positive free cash flow of $1.4 billion in Q1 2026, supported by operating cash flow of $3.9 billion. Cash and short-term investments stood at approximately $44.7 billion.
Moody’s has affirmed Tesla’s Baa3 issuer rating with a stable outlook in periodic reviews, acknowledging the company’s EV leadership, technology strengths, including AI for autonomous vehicles, solid profitability, and strong liquidity.

However, the agency has also noted challenges in the automotive segment and expectations for margin pressures.
Musk’s critique highlights a common debate about how traditional rating methodologies apply to high-growth, capital-intensive technology companies. SpaceX benefits from long-term government-backed contracts and diversified, recurring revenue streams, while Tesla’s valuation reflects heavy investment in future technologies such as autonomy and robotics.
Both ratings remain investment-grade, yet the one-notch difference has fueled online discussion about potential inconsistencies in evaluating innovative firms.
The exchange comes as SpaceX explores financing options following its recent valuation milestones, while Tesla continues executing on its multi-year roadmap. Musk’s pointed response serves as a reminder that credit ratings, though influential for borrowing costs, represent one lens through which markets assess corporate strength—and that company leaders often view their financial positions through the lens of long-term innovation and cash generation rather than short-term risk metrics alone.
A new report from Reuters claims that a transport authority in Sweden is pushing back against the approval of Tesla’s Full Self-Driving suite because it will travel over speed limits.
The report says the Swedish Transport Administration (TRV) recommends the European Union votes against FSD’s approval. TRV believes it should not be approved until Tesla disables FSD’s ability to speed.
TRV sent a letter to the European Union’s Technical Committee on Motor Vehicles (TCMV), which is set to meet on June 30 to discuss the potential approval of the Tesla FSD suite in the country. Tesla, which has received various approvals in Europe over the past two months, has not provided a comment.
Teslas operating on FSD do travel over the speed limit, depending on the Speed Profile that is chosen. Drivers have the ability to disengage FSD at any point; Tesla specifically states that those supervising the suite are responsible for its actions.
Let’s cut to the chase: humans operating any vehicle speed almost daily in the United States. Realistically, speed limits in the U.S. are more frequently treated as speed minimums. However, other countries are different, and driving behaviors are less aggressive.
TRV believes that “allowing automated systems to systematically exceed legal speed limits…risks undermining both the legal framework and the expected safety benefits of vehicle automation,” the report stated. It’s surprising that Tesla has not received this claim from other countries previously.
This could be a good argument to bring Max Speed back, the setting that previously allowed the driver to choose the absolute fastest the car would travel.
This would still put the responsibility of supervision in the hands of the driver. It would allow the driver to choose whether the car would travel over the speed limit or not, acknowledging that they set the speed, and if they get pulled over, there would be no ability to argue it.
However, it does not seem as if this is something Tesla will do, especially considering many U.S. drivers have requested the feature in an effort to eliminate speeding or at least tone it down. The company has not shown any interest in bringing it back.
Tesla has approvals for FSD in Europe in Estonia, Lithuania, Denmark, the Netherlands, and Belgium.
