  • SpaceX is heading back to the ISS on its 18th resupply mission for NASA.

  • This mission is packed with science experiments from bioprinting organs to researching the

  • effects of microgravity on the human body to soccer balls and even slime?

  • Yup, that’s right, Nickelodeon is studying slime in space, all these sent up with the

  • hopes of expanding our knowledge of life in microgravity.

  • As part of that goal, Expedition 60 crew member Andrew Morgan will be the latest NASA astronaut

  • to join the ISS crew.

  • Itll be his first mission to space and he’s been given the rare opportunity to

  • stay on board for a much longer period than his peers.

  • Usually, astronauts stay onboard the ISS for about 6 months, but for Morgan hell be staying for nine

  • to conduct groundbreaking microgravity research on the human body that will continue where

  • Scott and Mark Kelly’s twin study left off.

  • Well certainly, I'm very interested in those experiments that have a medical bent to them because we want

  • to study and understand how the human body changes over long periods of time in microgravity.

  • And he won’t be alone in this mission, as fellow NASA astronaut Christina Koch has been

  • selected to stay in space just shy of Scott’s 340-day record.

  • Over the duration of her stay, Koch will be the subject of a study that will demonstrate

  • the effects of long-term spaceflight on the female body for the very first time.

  • Well be diving into this in an upcoming episode so stay tuned.

  • In total, the ISS crew will be busy working on around 250 experiments including the first

  • U.S. bioprinter to be sent to the station by Techshot.

  • Their system is called the BioFabrication Facility or BFF, an experiment aiming to one

  • day print organ-like tissues in space.

  • Bioprinting soft tissues on Earth can be a challenge as tissues can collapse under their

  • own weight, so printing in microgravity becomes a huge advantage as it removes the need for

  • scaffolds that usually hold difficult structures.

  • The BFF works by printing the tissue cells inside cassettes, which are then placed into

  • an incubator system using Techshot’s ADvanced Space Experimenter Processor.

  • After up to 45 days of maturation, the tissue will retain its shape upon its return to Earth.

  • And theyre aiming for the stars to try to achieve something that’s never been done

  • before in the field of 3d bioprinting.

  • So that's the first thing that we're going to try to do is create something that has

  • a blood vessel component to it, muscularized tissue that's a centimeter thick.

  • These advances in 3D bioprinting present a huge opportunity for personalized medicine.

  • By using a patient’s own cells to print an organ, their bodies would have an easier

  • time accepting the new organ and would remove the need for anti-rejection drugs.

  • And seeing this project near usability is a dream come true for Eugene.

  • I still get goosebumps.

  • I mean, this was one of those crazy back room conversations that like, "Hey, you know,

  • wouldn't it be cool if ..." But this one, you know, right time, right place, right people,

  • right team, and all of a sudden, we're T-minus three weeks from watching a really big candle

  • get lit down in Florida.

  • Eugene isn’t the only researcher who’s got a lot riding on this mission.

  • The U.S. ISS National Lab is sending 25 scientific projects, an all-time high for a resupply

  • mission, of which 17 are private-sector projects sponsored by the lab.

  • Goodyear is sending materials in order to test the production of new silica forms and

  • structures in space that could help inform future evaluations of manufacturing tires

  • on the ground.

  • Adidas is including its soccer balls to study how a spherical, free-flying object rotates

  • in space that could help inform how free-flying objects interact with their environment.

  • And then there’s Nickelodeon, wholl be filming how slime acts in microgravity in

  • an effort to teach its young viewers about the basics of fluid dynamics.

  • And there’s one pretty big element left on this mission.

  • Sitting in the trunk of the Dragon cargo is an International Docking Adapter or IDA.

  • Built by Boeing, the IDA-3 converts the older, APAS to the NASA docking system, allowing

  • newer spacecraft like the Starliner and Crew Dragon, to autonomously connect with the space

  • station for the first time, using lasers and sensors to digitally communicate distance

  • cues, alignment guides, and final connection.

  • The docking system has also been designed to welcome spacecraft yet to be designed from

  • any space agency in the world.

  • I think it will enhance our cooperation because we fully intend to continue to fly astronauts

  • and cosmonauts from different communities on either vehicle and also just another real

  • honor for us to be up there potentially when these vehicles visit for the first time.

  • And hopefully, that historic moment will come soon.

  • So while we wait for the arrival of SpaceX’s crew Dragon and Boeing’s Starliner, we can

  • look forward to the incredible science happening above in continuing to explore the endless

  • boundaries of space.

  • Are there any experiments that you’d like us to cover more in depth?

  • Tell us in the comments below.

  • Make sure to subscribe and keep coming back to Seeker.

  • Thanks for watching.
