NASA astronauts Jessica Meir and Anil Menon concluded their spacewalk outside the International Space Station at 3 p.m. EDT. It was Menon’s first spacewalk and Meir’s sixth.

During the 6-hour, 27-minute spacewalk, Meir and Menon completed their primary objectives, which included preparing the 3B power channel. This work will enable the future installation of roll-out solar arrays, called IROSA, to provide additional power for the orbiting laboratory, supporting critical systems and the safe, controlled deorbit of the space station.

This was the 281st spacewalk in support of space station assembly, maintenance, and upgrades.

Educators & Teens Get Hands-On With TEMPO Data to Help Investigate Local Air Quality

A workshop participant, seen from behind, sits at a laptop displaying the TEMPO-Lab Data Viewer. The screen shows a colorful satellite map of air quality data over the central United States, with toggleable data layers for NO2, HCHO, ozone, and fire detections listed on the left panel. The participant holds a small notebook and pen while working through the tool at a table scattered with sticky notes and water bottles.

The NASA Science Activation Program’s Cosmic Storytelling with NASA Data (CosmicDS) project, led by Harvard University in Cambridge, Massachusetts, works to bring authentic NASA data into the hands of educators and learners. From July 27–29, 2026, the CosmicDS team partnered with the Smithsonian Institution’s BEST AQI (Breathing Easier: Supporting Teen Air Quality Investigations) project to host a Leadership Institute at the Center for Astrophysics | Harvard & Smithsonian (CfA) in Cambridge, MA. The Institute brought together 13 formal and informal educators who serve as advisors to BEST AQI, an initiative that guides teens through their own air quality research to support actions that improve air quality in their communities.

On Day 1 of the Institute, the CosmicDS Science Principal Investigator Pat Udomprasert led a hands-on immersion session introducing educators to TEMPO-Lab, a free online tool built with NASA Science Activation Program funding. TEMPO-Lab lets learners explore and analyze near-real-time air quality measurements collected by NASA’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) mission, which measures pollution across North America hourly during daylight hours. During Days 2 and 3 of the Institute, as educators worked together to co-develop BEST AQI curriculum and resources, they used TEMPO-Lab to build case studies covering a variety of real-world air quality scenarios, including wildfire smoke and emissions from rush-hour traffic, power plants, and agriculture. These case studies will give the teens in their programs a strong foundation for investigating air quality where they live and deciding what actions they might take in their own communities.

One moment made the workshop especially memorable. During a science briefing, TEMPO scientist Heesung Chong shared that a new beta-version ground-level ozone data product had recently become available. TEMPO-Lab’s flexible design made it possible for CosmicDS software developer John Lewis to integrate the new data product into the tool overnight, letting workshop participants explore cutting-edge ozone data themselves the very next morning. It was a striking example of how CosmicDS’s data tools can match the pace of active NASA science, giving educators and their learners access to data almost as soon as scientists themselves do.

“The BEST AQI Leadership Institute reinforced the value of the TEMPO-Lab as a tool for empowering youth to investigate local air quality issues using authentic NASA data. Educators were excited not only by the scientific capabilities of the platform, but by its potential to help young people use evidence to make informed decisions and contribute to positive change in their communities.”

— Erika Wright, Education Specialist, Smithsonian Astrophysical Observatory (SAO), and BEST AQI Principal Investigator

Equipping educators with both the technical skills and the curriculum to bring NASA air quality data into their classrooms matters because it builds data literacy skills that teens can carry into any career, while also giving them the tools to investigate issues that affect their health and their own communities. Air quality is a subject teens can see, smell, and feel the effects of — and BEST AQI is designed to help them turn that lived experience into evidence-based understanding and, ultimately, action.

The CosmicDS team will continue supporting these efforts in the year ahead. The 13 educators who attended this Leadership Institute plan to share the BEST AQI toolkit and TEMPO-Lab with approximately 100 additional educators across their partner sites in South Dakota, Maryland, and New York, potentially extending this work to thousands of teen air quality researchers.

Cosmic DS is supported by NASA cooperative agreement award number 80NSSC21M0002 and is part of the NASA Science Activation Program portfolio, which connects learners with authentic NASA science experiences through partnerships with educators and community organizations.

NASA’s SkyFall Helicopters at Work (Artist’s Concept)

NASA’s SkyFall Helicopters at Work (Artist’s Concept)

Description

This artist’s concept depicts NASA’s three SkyFall Mars helicopters collecting data while flying over the surface of the Red Planet. 

The green frequency waves emanating from the helicopters’ large antennas depict collection of subsurface radar data. The red beams depict collect near-infrared imagery data from regolith (crushed rock and dust) and other surface features.

Equipped with four instruments each, the three helicopters will follow in the footsteps of the agency’s Ingenuity Mars Helicopter, a technology demonstrator that flew 72 times over nearly three years, proving that powered, controlled flight is possible in the rarefied Martian atmosphere. It also demonstrated how an aerial perspective can generate valuabledata by helping NASA’s Perseverance Mars rover team plan time-saving routes and choose locations for science-gathering. 

SkyFall is expected to launch aboard NASA’s Space Reactor-1 Freedom in late 2028. 

The SkyFall project, which will carry three Mars helicopters to the Red Planet in December 2028, is managed by NASA’s Jet Propulsion Laboratory. AeroVironment of Arlington, Virginia — which worked with JPL to design and build the history-making Ingenuity rotorcraft — will co-design and co-manufacture the SkyFall helicopters. Managed by Caltech for NASA, JPL manages the overall Mars Exploration Program on behalf of NASA’s Science Mission Directorate in Washington.

Description

SkyFall ground-penetrating radar engineer Maya Román connects a coaxial cable to a test antenna in the Environmental Test Lab’s electromagnetic interference testing chamber at NASA’s Jet Propulsion Laboratory in Southern California. 

The antenna was pointed up during test to minimize reflections and interferences with the antenna pattern during the measurement.

Equipped with four instruments each, the three SkyFall aircraft will follow in the footsteps of the agency’s Ingenuity Mars Helicopter, which flew 72 times over nearly three years, proving that powered, controlled flight is possible in the rarefied Martian atmosphere. It also demonstrated how an aerial perspective can generate valuable data by helping NASA’s Perseverance Mars rover team plan time-saving routes and choose locations for science-gathering.
