3D printed organs are coming to an International Space Station near you
Two high-tech companies have teamed up to take 3D printing in space to the next level. A new 3D printer, sent to the space station on a SpaceX cargo resupply mission last July, is now officially open for business. It’s goal: to print human tissue in space.
Formally known as the 3D BioFabrication Facility (or BFF), the printer will use adult human cells (like stem cells) as its feedstock. The BFF is just the first step to a much larger goal of printing human organs — such as hearts or lungs — in space.
“The initial phase for BFF, which could last about two years, will involve creating test prints of cardiac-like tissue of increasing thickness,” Techshot representatives said in a statement. (Techshot is collaborating on the project with nScrypt, a 3D bioprinter and electronic printer manufacturer.)
If all goes according to plan, the company would then graduate to printing heart patches in space. Once printed, they would be shipped back to Earth and tested in small animals (such as rats) to see how they do. The next step after that could be entire organs.
“Ultimately, long-term success of BFF could lead to reducing the current shortage of donor organs and eliminate the requirement that someone must first die in order for another person to receive a new heart, other organ or tissue,” Techshot said.
Imagine needing a organ and instead of having to wait on the transplant list for an one that could never come, using a bit of your own DNA, a new organ could be printed for you in space.
Researchers on Earth have celebrated some success with the 3D printing of bones and cartilage, but when it comes to soft tissues, they haven’t had the same luck.
Tissues collapse under their own weight due to gravity. This results in not much more than a puddle of biomaterial. But when these sames components are used in space, they retain their shape.
However, without additional conditioning, once these new tissues return to Earth, they’d collapse just like there terrestrial counterparts. Here’s where BFF comes in.
In addition to launching a bioprinter, Techshot has also developed a means of curing the newly printed tissues. This way they will remain solid even after returning to Earth. The company says that the actual printing process will take less than a day, the strengthening process will take an estimated 12-45 days. It all depends on the tissue.
This could lead to less people dying as they wait on transplant lists, and it could also mean less dependency on anti-rejection medications. Assembling a whole human organ (such as a heart or lung) was once strictly science fiction. While it’s still a few years away, it is now a possibility.

Elon Musk called it Epic: The full story of SpaceX’s Starship Flight 12
Starship V3 reached space, survived reentry, and proved it can fly with engines out.
After two scrubbed attempts, SpaceX launched Starship V3 on Friday, May 22 from the brand new Pad 2 at Starbase, Texas, completing the most technically complex test flight the program has attempted and moving the bar in ways that matter for everything from commercial satellites to the first human Moon landing since 1972.
The Super Heavy booster lost an engine early during ascent and several more failed during its boostback burn, sending the stage into an off-nominal descent that ended in a hard landing in the Gulf of Mexico. SpaceX had planned a soft splashdown rather than a tower catch on this first V3 flight, so losing the booster was expected to be acceptable within the test parameters.
Ship 39 told a different story. The Starship upper stage reached its planned sub-orbital trajectory despite losing one of its vacuum Raptor engines, with the remaining engines compensating for the loss and keeping the vehicle on course. The spacecraft then survived atmospheric reentry, completed its belly-flip maneuver, and made a controlled upright splashdown in the Indian Ocean west of Australia.

The payload test is where Flight 12 separated itself from every previous Starship mission. SpaceX deployed 22 objects including 20 Starlink simulator satellites sized like next-generation V3 Starlink units, plus two specially modified satellites equipped with cameras that scanned Starship’s heat shield from orbit and transmitted imagery back to operators.
The broader significance of what was tested on Friday goes well beyond one mission. Every future Starship deployment, whether it is a batch of operational Starlink V3 satellites, cargo bound for the Moon, or eventually crew headed to Mars, depends on SpaceX being able to inspect and certify the heat shield quickly between flights. The camera-equipped satellites deployed on Flight 12 are the first step toward making that inspection process automated and data-driven rather than manual and time-consuming. If SpaceX can scan the heat shield from orbit after every reentry and flag damaged or missing tiles before the vehicle even lands, it fundamentally changes the turnaround time between flights. For a program that needs to refuel Starship in orbit using ten or more tanker launches before a single Moon mission can depart, launch cadence is everything. Friday’s payload test can be seen as building the maintenance infrastructure for rapid reusability.
Elon Musk took to X, following the successful tests, and noting: “Congratulations @SpaceX team on an epic first Starship V3 launch and landing!” “You scored a goal for humanity.”
The stakes behind that goal are concrete. NASA has selected Starship as the Human Landing System for Artemis IV, targeting a crewed Moon landing in 2028, and SpaceX has yet to demonstrate a full orbital flight, in-orbit refueling, or docking with an Orion capsule. Flight 12 proved V3 can fly, survive reentry, and deploy payloads under engine-out conditions. That is the foundation everything else has to be built on, and with a SpaceX IPO targeting June 2026, the timing of that proof of concept could not have been more useful.
SpaceX has decided to stand down from what was supposed to be the first test launch of Starship’s v3 rocket tonight after a minor issue with a hydraulic pin delayed the flight once more.
The company scrubbed its first test flight of the upgraded Starship v3 on May 21 in the final minutes of the countdown. SpaceX CEO Elon Musk quickly took to social media platform X, explaining that a hydraulic pin on the launch tower’s “chopsticks” arm failed to retract properly.
Musk added that the company would fix the issue this evening. SpaceX will attempt another launch tomorrow night at 5:30 p.m. CT, 6:30 p.m. ET, and 3:30 p.m. PT.
The hydraulic pin holding the tower arm in place did not retract.
If that can be fixed tonight, there will be another launch attempt tomorrow at 5:30 CT. https://t.co/DJAdvDYQpH

The countdown for Starship Flight 12 — featuring the taller and more capable V3 stack with Booster 19 and Ship 39 — had been progressing smoothly until the late-stage issue surfaced. The Mechazilla tower arm, designed to secure the vehicle on the pad and eventually catch returning boosters, could not complete its retraction sequence.
SpaceX teams immediately began troubleshooting the hydraulic system for an overnight repair.
Starship V3 introduces several significant upgrades over earlier versions. These include greater propellant capacity, more powerful Raptor 3 engines, larger grid fins, enhanced heat shielding, and an improved fuel transfer system.
We covered the changes that were announced just days ago by SpaceX:
SpaceX unveils sweeping Starship V3 upgrades ahead of May 19 launch
The changes are intended to increase payload performance, support higher flight rates, and advance the vehicle toward operational missions, including Starlink deployments, NASA Artemis lunar landings, and future crewed Mars flights. The debut flight from Starbase’s new Launch Pad 2 marked an important milestone in scaling up the fully reusable Starship system.
This stand-down highlights the intricate challenges of preparing the world’s most powerful rocket for flight. Despite extensive pre-launch checks, a single component in the ground support equipment can force a scrub.
The incident aligns with Starship’s proven iterative development approach. Previous test flights have encountered both successes and setbacks, each providing critical data that refines hardware and procedures. Some outlets may call some of these flights “failures,” when in reality, they are all opportunities for SpaceX to learn for the next attempt.
With V3, SpaceX aims to reduce ground-system dependencies and increase launch cadence to meet ambitious long-term goals.
SpaceX has revealed the date for the maiden voyage of Starship v3, its newest and most advanced version of the rocket yet.
Starship v3 represents a significant leap forward. At 124 meters tall when fully stacked, it stands taller than previous versions and boasts substantial upgrades.
The vehicle incorporates next-generation Raptor 3 engines, which deliver higher thrust, improved reliability, and simplified designs with fewer parts. Both the Super Heavy booster (Booster 19) and the Starship upper stage (Ship 39) feature these enhancements, along with structural improvements for greater payload capacity—exceeding 100 metric tons to low Earth orbit in reusable configuration.
SpaceX and its CEO Elon Musk have announced that the company aims to push the first launch of Starship v3 this Thursday. Musk included some clips of past Starship launches with the announcement.

There are a lot of improvements to Starship v3 from past builds. Key hardware changes include a more robust heat shield, upgraded avionics, and modifications optimized for orbital refueling, a critical technology for future missions to the Moon and Mars. This flight marks the first launch from Starbase’s second orbital pad, allowing parallel operations and accelerating the cadence of tests.
This will be the 12th Starship launch for SpaceX. Flight 12 objectives include a full ascent profile, hot-staging separation, in-space engine relights, and reentry testing. The booster is expected to perform a controlled splashdown in the Gulf of Mexico, while the ship will deploy 20 Starlink simulator satellites and a pair of modified Starlink V3 units before attempting reentry.
Success would validate V3’s design for operational use, paving the way for rapid reusability and higher flight rates.
The rapid evolution from V2 to V3 underscores SpaceX’s iterative approach. Previous flights demonstrated booster catches, ship landings, and heat shield advancements. V3 builds on these with nearly every component refined, supported by an expanding production line at Starbase that churns out vehicles at an unprecedented pace.
Starship V3 is here putting SpaceX closer to Mars than it has ever been
This launch comes amid growing momentum for SpaceX’s ambitious goals. Starship is central to NASA’s Artemis program for lunar landings and Elon Musk’s vision of making humanity multiplanetary. A successful V3 debut would boost confidence in achieving orbital refueling and crewed missions in the coming years.
As excitement builds, enthusiasts and engineers alike await liftoff. Weather and technical readiness will determine the exact timing, but the community is optimistic. Starship V3 is poised to push the boundaries of spaceflight once again, bringing reusable interplanetary transport closer to reality.
