Tissue chips, thumb-drive sized devices that contain human cells in a 3D matrix, represent a giant leap in science.
They can test cells’ response to:
•stresses
•drugs
•genetic changes
The Tissue Chips in Space initiative seeks to better understand the role of microgravity on human health and disease and to translate that understanding to improved human health on Earth.
This series of investigations to test tissue chips in microgravity aboard the International Space Station is planned through a collaboration between the National Center for Advancing Translational Sciences (NCATS) at the National Institutes for Health (NIH) and the National Laboratory in partnership with NASA.
Many of the changes in the human body caused by microgravity resemble the onset and progression of diseases associated with aging on Earth, but in space, changes occur much faster. Scientists may be able to use tissue chips in space to model changes that take months or years to happen on Earth.
A tissue chip needs three properties, according to Lucie Low, scientific program manager at NCATS. “It has to be 3D,” she explained. “It must have multiple different types of cells, and it must have microfluidic channels. Essentially, you get a functional unit of what human tissues are like, outside of the body,” said Low.
As accurate models of the structure and function of human organs, tissue chips provide a model for predicting whether a drug, vaccine or biologic agent is safe in humans more quickly and effectively than current methods.
This first phase of Tissue Chips in Space includes five investigations. An investigation of immune system aging is planned for launch on the SpaceX CRS-16 flight, scheduled for mid-November. The other four, scheduled to launch on subsequent flights, include lung host defense, the blood-brain barrier, musculoskeletal disease and kidney function. This phase tests the effects of microgravity on the tissue chips and demonstrates the capability of the automated system.
All five investigations make a second flight about 18 months later to confirm use of the model, such as testing potential drugs on the particular organs. Four more projects are scheduled for launch in summer 2020, including two on engineered heart tissue to understand cardiovascular health, one on muscle wasting and another on gut inflammation.
Ultimately, the technology could allow astronauts going into space to take along personalized chips that could be used to monitor changes in their bodies and to test possible countermeasures and therapies. That would be a major leap forward in keeping astronauts healthy on missions to deep space!

This Friday, Aug. 19, two U.S. astronauts will install a new gateway for American commercial crew spacecraft at the International Space Station.
Commercial crew flights from Florida’s Space Coast to the International Space Station will restore America’s human spaceflight launch capability and increase the time U.S. crews can dedicate to scientific research.
The adapter being installed (imaged below) was launched on a SpaceX Dragon cargo spacecraft and arrived on orbit July 20. NASA astronauts Jeff Williams and Kate Rubins will perform the spacewalk to install the equipment this Friday, Aug. 19. This will be the fourth spacewalk in Williams’ career and the first for Rubins.
Four previous spacewalks…like the one below…helped set the stage for installation of this docking adapter. During those previous spacewalks, other crew members laid hundreds of feet of power and data cables outside the space station.
On Wednesday, the robotics team using the Canadarm2 and its attached “Dextre” manipulator, will reach into the SpaceX Dragon trunk and pull out the docking adapter and position it for Friday’s spacewalk activities.
The morning of the spacewalk, while the astronauts are getting suited up, the robotic arm will position the docking adaptor near the port so that it will be ready for installation.
The two astronauts will venture outside the space station to install the first International Docking Adapter (IDA). This new adapter port will provide a parking space for U.S. Commercial Crew vehicles.
Coverage of the spacewalk begins at 6:30 a.m. EDT on Friday, Aug. 19; with the spacewalk scheduled to begin at 8:05 a.m. EDT. Stream live online HERE.

@nasajohnson NBL tour with #nasamei2017 on Monday. (at NASA Neutral Buoyancy Laboratory)
Today, Astronaut Scott Kelly has broken the record for longest time spent in space by a U.S. astronaut! Over the course of his four missions, Kelly has spent 383 cumulative days in space. This record was previously held by Astronaut Mike Fincke, with 382 days in space over three flights. Here are some more fun facts about this milestone:
4: The number of humans that have spent a year or more in orbit on a single mission
215 Days: The record currently held by Mike Lopez-Alegria for most time on a single spaceflight by U.S. astronaut. On Oct. 29, Kelly will break this record
377 Days: The current record for most days in space by a U.S. female astronaut, held by Peggy Whitson
879 Days: The record for most cumulative days in space by a human, currently held by Russian cosmonaut Gennady Padalka
Why Spend a Year in Space?
Kelly’s One-Year Mission is an important stepping stone on our journey to Mars and other deep space destinations. These investigations are expected to yield beneficial knowledge on the medical, psychological and biomedical challenges faced by astronauts during long-duration spaceflight.
Kelly is also involved in the Twins Study, which consists of ten separate investigations that are being conducted with his twin brother, who is on Earth. Since we are able to study two individuals who have the same genetics, but are in different environments for one year, we can gain a broader insight into the subtle effects and changes that may occur in spaceflight.

Orion Nebula in Oxygen, Hydrogen, and Sulfur Image Credit Copyright: César Blanco González
The Orion Nebula is among the most intensely studied celestial features.The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust.
Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.
The title says it all...MAKING Video Games...FOR NASA! :)
2017 - Johnson Space Center Year in Review
1. What a Long, Strange—and Revealing—Trip It’s Been
As the Cassini mission builds toward its climactic “Grand Finale,” we’re taking a look back at the epic story of its journey among Saturn’s mini-solar system of rings and moons.
+ Traverse the timeline
2. Our Very Own Moon
Unlike Saturn, Earth has only one moon. Let’s celebrate it! International Observe the Moon Night (InOMN) is a worldwide, public celebration of lunar science and exploration held annually. On Oct. 8, everyone on Earth is invited to observe and learn about the moon together, and to celebrate the cultural and personal connections we all have with it.
+ Join in
3. What’s Up, October?
Even more about Earth’s moon is the subject of this month’s video guide for sky watchers and includes a look at the moon’s phases and when to observe them. Also featured are a guide to upcoming meteor showers and tips on how to catch a glimpse of Saturn.
+ Take a look
4. Nine Lives
Dawn’s discoveries continue, even as the asteroid belt mission marks nine years in space. “For such an overachiever,” writes Dawn’s top scientist, “it’s fitting that now, on its ninth anniversary, the spacecraft is engaged in activities entirely unimagined on its eighth.”
+ Learn more
5. The Incredible Shrinking Mercury
It’s small, it’s hot, and it’s shrinking. Research funded by us suggests that Mercury is contracting even today. This means we now know that Mercury joins Earth as a tectonically active planet.
+ Get the small details
