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.
SpaceX CEO Elon Musk announced today that the company will likely attempt to catch the Starship upper stage with its launch tower arms “in a few months.”
In a post on X, Musk wrote, “Looks like we will probably catch the ship with the tower in a few months. If there had been a tower out to sea where we practiced landing the ship, it would have been caught.” He added that the first reflight of a Starship vehicle is expected by the end of 2026 or early 2027, describing it as “a fork in the road of history for consciousness reaching the stars.”
Looks like we will probably catch the ship with the tower in a few months. If there had been a tower out to sea where we practiced landing the ship, it would have been caught.
First reflight of the ship will be either end of this year or early next. That will be a fork in the… https://t.co/O5g9pqrzyo

Musk’s prediction comes amid ongoing progress toward full reusability of the Starship system, a two-stage rocket designed for rapid turnaround and dramatically lower launch costs. Catching the upper stage, known simply as “ship,” with the Mechazilla tower’s mechanical arms would mark a major milestone. It would allow both stages to return directly to the launch site for quick refurbishment and reuse, eliminating the need for ocean recovery.
Musk has previously signaled plans for a ship catch. In July, shortly after SpaceX’s wildly successful Starship 13 mission, he stated that the company would attempt to catch the ship with the tower on the next flight unless problems emerged in the mission data review. Earlier comments also outline conditions such as successful soft ocean landings before attempting a land recovery to minimize risk.
SpaceX has solved Starship’s biggest challenge, Elon Musk says
The latest update from Musk adjusts this timeline to a few months, reflecting the iterative nature of the test campaign.
SpaceX has already demonstrated the tower catch technique successfully with the Super Heavy booster on a couple of occasions. The first successful booster catch occurred during Flight 5 in October 2024, when the massive first stage returned to the Starbase pad in Texas and was plucked from the air by the tower arms.
Additional catches followed on later flights, including Flight 7, proving the concept for the booster and building confidence in the system as a whole.
Achieving a similar catch for the upper stage would represent a significant step forward. The ship returns from much higher speeds and greater heat loads after orbital or near-orbital flight. Success would advance SpaceX’s goal of full and rapid reusability, potentially reducing the cost of access to orbit by a factor of 100 or more and supporting ambitions for frequent satellite deployments, lunar missions, and eventual Mars flights.
Musk has long emphasized that true reusability, refueling rather than discarding hardware, is essential for making humanity a multi-planetary species.
As SpaceX continues refining Starship through successive test flights, the coming months will test whether the ambitious catch timeline can be met. The combination of prior booster successes and improving ship landing precision suggests the company is steadily closing in on this historic capability.
SpaceX has achieved an incredible milestone by launching its 11,000th Starlink satellite into orbit.
This accomplishment occurred during the Starlink Group 17-50 mission, which lifted off on August 19 at 04:01 UTC from Space Launch Complex 4 East at Vandenberg Space Force Base in California.

A Falcon 9 rocket carried 24 Starlink V2 Mini satellites on this flight, successfully deploying them into low Earth orbit approximately one hour after liftoff. The first stage booster, identified as B1097 on its twelfth flight, landed successfully on the droneship Of Course I Still Love You in the Pacific Ocean.
According to tracking data compiled around that date, this deployment brought the total number of Starlink satellites in orbit to just over 11,000.
The Starlink program began with test satellites known as Tintin A and B, launched on February 22, 2018. The first operational batch of 60 Starlink satellites followed on May 24, 2019, when a Falcon 9 rocket lifted off from Cape Canaveral. Those initial satellites marked the start of a rapid expansion that has continued for more than seven years.
SpaceX has conducted hundreds of dedicated Starlink missions since then, routinely launching batches of 20 to 30 satellites at a time using reusable Falcon 9 rockets. By mid-2026, the company had already surpassed 12,000 total satellites launched across all versions, with continuous replacements for units that deorbit as designed to manage space debris.
Looking ahead, SpaceX continues to expand the Starlink constellation to enhance global broadband coverage, capacity, and speed. The network already serves millions of users across more than 160 countries and supports applications ranging from residential internet to maritime, aviation, and emergency services.
Future plans center on next-generation hardware, including larger V3 satellites capable of delivering substantially higher throughput, which require the increased payload capacity of the Starship vehicle currently under development and testing.
In July, SpaceX submitted an application to the Federal Communications Commission seeking authority for a Gen3 constellation of up to 100,000 satellites. These spacecraft would operate in very low Earth orbit shells at altitudes near 325 kilometers and 475 kilometers. The filing requests use of existing Ku, Ka, V, and E band spectrum along with new greenfield W and D band frequencies between 92 and 275 GHz.
SpaceX states that the expanded system aims to deliver multi-gigabit symmetrical broadband to consumers, enterprises, governments, and billions of AI-powered devices worldwide while handling a majority of global internet traffic. Approval and subsequent deployment would depend on regulatory review and the operational readiness of Starship for high-volume launches.
This ambitious scale reflects SpaceX’s ongoing commitment to providing ubiquitous high-speed connectivity from space.
Tesla has opened a new sweepstakes to allow the public to be among the first to take an initial ride in a Cybercab. This all-electric, steering-wheel-less, pedal-less vehicle is the centerpiece of the company’s autonomous ride-hailing platform, Robotaxi.
There are two ways Tesla fans can get to Austin to take part in the first public rides of the Cybercab: by riding on the Robotaxi platform by August 23, or by mailing a very specific entry to their Headquarters at Gigafactory Texas.
Tesla announced the latter portion of the sweepstakes last night:
🚨 Want to win a trip to Austin to ride in one of the first Cybercab rides ever?
Here’s how:

There is a limit of one entry per stamped envelope. You can send as many as you’d like, but they must be in separate envelopes.
The company’s unique strategy to give people the opportunity to ride in a Cybercab before pretty much anyone else outside of the company is a hilarious but spot-on representation of how Tesla operates. In classic fashion, they had the perfect response to the event:

Cybercab will launch later this month, it appears, especially as it plans to announce the winners of the sweepstakes on August 25. The car has already been operating internally, as employees have been able to utilize the Cybercab for rides in some capacity, something it announced earlier this month.
Tesla weirdly confirms Cybercab employee rides, a huge milestone
Moving forward, the big goal is to get Cybercab out on the roads and integrated into the public Robotaxi fleet, one that will pick up real-world ride-hailers and give them a ride from Point A to Point B.
No matter which way you cut it, it appears Tesla is close to putting a vehicle with no steering wheel and no pedals on the road to help people travel autonomously.
