As part of NASA’s ongoing Inspiration Tour, NASA astronaut Christina Koch will highlight America’s strengths in space exploration and aeronautics innovation at the Philadelphia Eagles vs. Los Angeles Rams game in Philadelphia on Sunday, Oct. 4.

A self-proclaimed Philadelphia sports fan, Koch is an explorer and engineer who spent a total of 338 days in space across two missions, including serving as a mission specialist for the agency’s Artemis II mission earlier this year. On April 1, Koch launched from NASA’s Kennedy Space Center in Florida aboard the Orion spacecraft on top of the agency’s SLS (Space Launch System) rocket as part of Artemis II. Koch and her fellow crew members completed a historic lunar flyby, marking humanity’s return to the vicinity of the Moon for the first time in more than 50 years.

NASA team members will engage with fans at the agency’s Experience Zone, located outside the stadium from 10 a.m. to 1 p.m. before the game. Fans can learn more about NASA’s return to the Moon through the agency’s Artemis program, enjoy interactive games, and capture photos at a selfie station and with a large, inflatable NASA logo.

With stops across the nation, NASA’s Inspiration Tour convenes academic, industry, and public sector stakeholders to connect the agency with the people, technologies, and organizations that drive American leadership in space.

The tour will culminate in MAX POWER, a public exposition of American air and space innovation, Saturday, Nov. 7, and Sunday, Nov. 8, on and near the agency’s Kennedy Space Center in Florida. Held in honor of America’s historic 250th anniversary, the multi-day, family-friendly event will showcase the next-generation aircraft, spacecraft, autonomous vehicles, and technologies that will help define the future of transportation in air and space.

Heading Home: NASA’s SpaceX Crew-12 Concludes Station Science Mission

NASA’s SpaceX Crew-12 mission is ending, with the crew scheduled to return in early October. NASA astronauts Jessica Meir and Jack Hathaway, ESA (European Space Agency) astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev will head home from the International Space Station after supporting research that benefits life on Earth and prepares humans for missions into deep space.

Here’s a look back at some of their accomplishments:

Orbital transit

The crew members look out the window of a Dragon spacecraft during their journey to the space station, a destination that offers a unique vantage point to observe both Earth and the cosmos. Research in microgravity allows the scientific community to experiment through a new perspective, from changes in how cells behave to how materials take shape, space offers new paths to scientific discovery.

Learn more about research in microgravity.

Crystalline clues

Hathaway floats alongside hardware used for crystal growth experiments aboard the orbiting laboratory. Microgravity reveals new details about crystal structures, helping researchers improve the quality and stability of pharmaceuticals. Here, cancer-targeting treatments are crystallized to better understand their properties and help advance cancer therapies on Earth.

Learn more about the Pharmaceutical In-space Laboratory (ADSEP-PIL-15).

Boosting quantum science

Meir works with cables that deliver light used to cool, trap, and study atoms inside the Cold Atom Lab. In microgravity, ultracold atoms can be observed for longer periods, giving scientists a window to peer into the quantum realm. A recent upgrade to the facility increases the number of atoms produced, providing more data to advance quantum technologies such as solar cells and the components that power cell phones and computers.

Branching beyond bone loss

Adenot holds a small container that houses a bone scaffold made from wood, designed to mimic the structure of real bones and support the growth of bone cells. Since microgravity can accelerate bone loss, it offers a unique opportunity to test how well the scaffold promotes bone regeneration. Insights from this study could protect future space explorers and provide new treatment options for patients with osteoporosis, a disease that affects more than 200 million people globally.

In-space suspension

Meir sets up hardware for an investigation that studies soft materials made from tiny particles suspended in water. In microgravity, scientists can study how these particles interact and assemble into structures differently than they do on Earth. Understanding these interactions could help scientists fine-tune the texture, stability, and performance of materials used for growing plants, 3D printing, and producing pharmaceuticals.

Decoding microbial secrets

Hathaway holds equipment to test for antibiotic-resistant bacteria aboard the space station. Some bacteria can withstand antibiotics, starvation, and disinfection, making them a concern in closed environments like spacecraft. Sequencing DNA in microgravity can reveal how resilient microbes adapt to space, helping scientists identify countermeasures to manage antibiotic‑resistant bacteria during exploration missions while also advancing efforts to combat resistance on Earth.

Fresh delivery

Expedition 74 crew members smile among fresh produce delivered aboard NASA’s Northrop Grumman Commercial Resupply Services 24 mission. Cargo flights bring critical supplies, fresh food, sweet treats, and new science to the space station. The Cygnus XL spacecraft also delivered many research projects, including an instrument that could improve space-weather modeling and a project that could help protect gut-microbiome stability on future exploration missions.

Reshaping cartilage

Meir works on an investigation that studies how engineered cartilage tissue develops in microgravity, which may help scientists produce medical implants that more closely resemble natural cartilage. For millions of people with cartilage injuries, space-grown tissue could offer treatment options that don’t require transplanting cartilage from another part of the body.

Printing meets metal

Adenot installs the Metal 3D Printer aboard the orbital complex. Several small metal parts have already been 3D printed in microgravity and returned to Earth, where their quality is evaluated against those made on the ground. Producing metal parts on demand in space could give future crews the ability to make or replace what they need far from Earth, reducing reliance on spare parts and resupply missions.

Learn more about Metal 3D Printer.

Vital fluids

Adenot works to produce intravenous (IV) fluid on demand in microgravity. Commercial IV fluids expire after about 16 months and carrying them on long-duration missions adds weight and takes up valuable space. This system could provide a critical medical resource when resupply is limited and improve access in remote areas or during emergencies on Earth.

Learn more about Intravenous Fluid Generation – Mini (IVGEN Mini).

Multiplying stem cells

Hathaway takes a selfie as Meir conducts a stem cell investigation in space. Microgravity can help produce larger numbers of clinical-grade stem cells that retain their ability to transform into other cells. Cells used in this experiment could help rebuild blood and immune systems after chemotherapy, advancing care for leukemia and other blood diseases on Earth.

Learn more about the Hematopoietic Stem Cell Expansion in Space: Pathfinder Investigation (InSPA-StemCellEX-H2).

Training bone cells

Hathaway holds an experiment container that uses bone marrow cells to study how microgravity affects bone and muscle. The research uses structures that mimic parts of bone marrow, and some samples are exposed to vibrations that simulate exercise. Tracking changes in these cells could reveal new ways to combat bone and muscle loss during spaceflight and support bone health on Earth.

The engineering development unit for NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) probe is photographed prior to a major thermal evaluation.

The DAVINCI team put the yoga ball-sized vessel into a ceramic-lined chamber with heat-scorched walls and ratcheted up the temperature to 869 F, or 465 C, over the course of about an hour — the same pace the probe will heat up during its descent to the surface of Venus.

DAVINCI will study the origin, evolution, and present state of Venus in unprecedented detail to help determine whether it was once wet and habitable, like Earth.
