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.

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).
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.
Learn more about the Cold Atom Lab.
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.

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.
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.
Learn more about Biomimetic Tissue Engineering in Microgravity for Cartilage using Aggregate Rejuvenation, Tension, and Self-Assembly (BEM-CARTS).
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.
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).
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).
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.

The Wildhorse grass fire in eastern Idaho erupted with a massive pulse of smoke. No one had expected it, but the wildfire had launched what’s known as a pyrocumulonimbus cloud, or pyroCb. It was an elusive weather phenomenon that scientists on NASA’s INSPYRE (INjected Smoke and PYRocumulonimbus Experiment) campaign spent weeks this summer hunting across western North America.
Pyrocumulonimbus clouds rise above intense fires, producing lightning and rain along with powerful winds that can whip the flames below into a fury. The largest pyroCbs funnel smoke 30,000 to 50,000 feet (10 to 15 kilometers) above Earth’s surface, as high as the cruising altitudes of commercial jets and even into the stratosphere.
The significance of pyroCbs emerged around the turn of the 21st century, when satellite observations revealed smoke reaching altitudes previously associated with major volcanic eruptions. Once in the stratosphere, pyroCb smoke can spread across continents, circle the globe, and persist far longer than it would in the lower atmosphere.
Despite their massive size, pyroCb clouds remain mysterious. But it’s important to understand how they form and connect with the atmosphere, because their smoke can affect climate and weather far from the fires that produced them and long after they’ve extinguished. They also can produce dangerous fire-generated winds.
“We still do not understand if they’re driven by fire energetics, or fire intensity, or by atmospheric conditions above,” said Olga Kalashnikova, a researcher with NASA’s Jet Propulsion Laboratory in Southern California, who is one of the principal investigators leading INSPYRE, the first aircraft campaign designed specifically around studying pyroCbs.
For six weeks this summer, INSPYRE researchers climbed aboard a Gulfstream jet for a series of flights from the plane’s home base at the National Center for Atmospheric Research (NCAR) near Boulder, Colorado. Scientists collected smoke particles, sampled gases, photographed ice crystals, and monitored radiation passing through clouds and reflected back into space. The aircraft crisscrossed above, below, and through clouds to get a close-up view of fire-induced weather and smoke.
Meanwhile, NASA’s high-flying ER-2 aircraft, loaded with 14 instruments, tracked fire intensity, updraft speeds, smoke, and cloud properties from above, while crews drove trucks equipped with sensors to view the same events from the ground. Ultimately, the team will investigate how wildfire-generated clouds transport smoke upward, how clouds transform particles and gases in smoke, how much reaches the stratosphere, and what happens once it gets there.
Firefighters will benefit from a better understanding of when pyroCbs are likely to develop and how they affect fire conditions on the ground. “A unique thing about pyrocumulonimbus is they are fire-generated weather, meaning the fire makes its own weather,” said Neil Lareau, an atmospheric scientist at the University of Nevada, Reno, who led INSPYRE’s ground observations. “The fire is making its own thunderstorm, and in the process of doing that, it’s also making its own wind.”

Lareau hopes the research will lead to warnings comparable to the alerts meteorologists issue for severe thunderstorms. For example, he said, a forecast would warn firefighters that a developing cloud could soon produce a dangerous downdraft and wind shift, giving fire managers time to pull personnel off the line.
Additionally, INSPYRE could also improve Earth system models. PyroCbs can carry enormous quantities of smoke into the stratosphere, where particles can persist for months or longer and affect how much solar energy the atmosphere absorbs and how much reaches Earth’s surface. Most numerical prediction models don’t explicitly include the effects of pyroCbs and their smoke injections, said Dave Peterson, a Naval Research Laboratory meteorologist and INSPYRE’s co-principal investigator. Measurements of the particles, gases, and radiation associated with these events will give scientists data to test and improve simulations of their effects on Earth’s weather and climate.
To study wildfire smoke and clouds, and perhaps catch a pyroCb in action, the INSPYRE team first had to find one. The challenge was getting an aircraft to the right place at the right time. Pyrocumulonimbus clouds can develop in minutes and subside just as quickly, while reaching fires hundreds of miles away takes hours of preparation, flight time, and coordination with air traffic controllers.
But on Aug. 26, the team got lucky. The Gulfstream was returning from a fire farther west when Sarah Woods, a National Center for Atmospheric Research scientist serving as spotter, got word that the Wildhorse fire was unexpectedly intense.
The fire hadn’t initially attracted much attention. “We knew there was a grass fire there, and everyone’s like, it’s just a grass fire; we’re not going to worry about it,” Peterson said. “And it ended up being the main event.”

When the flight path neared the Wildhorse fire, Woods spotted the fresh remains of a pyroCb from her cramped jump seat behind the pilots. “It looks just like a big thunderstorm, and so as you approach it, you look for a visual indication of the fire on the ground,” said Woods.
Seeing the fire on the ground far below confirmed that the cloud was fire-generated. At Woods’ request, the pilots swung the plane around and spent the next three hours flying back and forth through the cloud plume and the trail of smoke drifting northwest toward Wyoming.
The chance encounter gave the INSPYRE team measurements of a pyroCb plume roughly an hour after the cloud first erupted. Other flights coordinated between the Gulfstream jet and ER-2 added crucial observations of active fire-driven atmospheric airflow that will help document how the resulting smoke plumes evolve over the days and weeks that follow.
Measurements from the Gulfstream and ER-2 will now be combined with satellite and ground observations and compared with models.
“When clouds form, they modify chemistry,” said Kalashnikova, the JPL-based principal investigator. That altered smoke can have different effects on radiation, she said, making it important to understand both how pyroCbs form and the smoke that emerges from them.
In the summer of 2026, the challenge was finding the clouds and collecting the measurements. Now comes the work of understanding what they found.
