Power Up: Roll Out Solar Arrays Boost Space Station Power Supply

From the International Space Station’s unique position 250 miles above Earth, the Sun is a vital source of energy. Solar power supports the station’s life support systems, daily activities, and hundreds of research investigations that improve life on Earth and prepare humans for deep space exploration. Over the past five years, NASA augmented the station’s power generation and distribution capability with next-generation International Space Station Roll Out Solar Arrays (IROSAs).

In 2017, a technology demonstration conducted aboard the space station tested the effectiveness of the arrays. The lightweight, compact design launches as a cylinder and unfurls like a yoga mat after installation. This advanced design reduces mass and volume at launch and uses an autonomous, self-deploying system that minimizes risks during rollout.

The technology is also scalable to meet mission requirements. The IROSAs are about half the size of the station’s legacy arrays. Despite being smaller, the arrays are capable of producing about 28 kilowatts of additional power.

Six IROSAs were installed outside of the space station between 2021 and 2023. In 2023, power projections prompted a request for another set of IROSAs, which launched in Dragon spacecraft’s trunk during the SpaceX 35th commercial resupply services mission to space station for NASA. Together, the eight IROSAs will increase power by more than 160kW for research and operations.

With the full upgrade in place, the space station’s revitalized power system not only supports NASA’s legacy in low Earth orbit but also helps advance technology that will extend the agency’s reach into the solar system. From planetary defense demonstrations, like the Double Asteroid Redirection Test, to future human exploration efforts, the space station is an essential testbed for the technologies needed for expeditions beyond Earth’s orbit.

NASA to Conduct Low-Altitude Flights Over Texas Farmland

A NASA Dynamic Aviation A200 aircraft will conduct low-flying research flights over farmland near Transit, Texas, from Thursday, Oct. 22, through Monday, Nov. 9. These flights will measure gaseous and particulate emissions from animal feeding operations.

Agricultural emissions represent an important and understudied part of Earth’s land and atmosphere systems. The FarmFlux mission will deploy more than a dozen sensors to measure ozone, methane, ammonia, particulates, and other pollutants rising from crop lands and livestock farms and their interaction with the Earth’s atmosphere. The mission is jointly led by NASA’s Goddard Space Flight Center in Greenbelt, Maryland; Colorado State University; and Boston University.

Additional low-altitude research flights with a NASA P-3 Orion aircraft are scheduled for the March to July 2027 growing season in the Midwest and California’s Central Valley with a focus on cropland.

NASA Welcomes All Ages, Experience Levels for Space Apps Challenge

Registration is open for the 2026 NASA Space Apps Challenge, a two-day global event on Saturday, Nov. 14 and Sunday, Nov. 15, where teams work to create solutions inspired by NASA’s most ambitious exploration goals and making use of the agency’s free and open data. The annual challenge, often called a hackathon, is an intensive, collaborative problem-solving experience where participants tackle real-world challenges created by NASA subject matter experts.

This year’s Space Apps Challenge collectively supports three major focus areas: returning humans to the Moon, preparing for missions deeper into the solar system, and expanding understanding of the universe. Participants do not have to be programmers. Students, scientists, engineers, designers, storytellers, technologists, and space enthusiasts of all ages and experience levels can contribute their skills.

“At NASA, science is for everyone, and we’re inviting the next generation to help tackle some of humanity’s most critical challenges in space through the NASA Space Apps Challenge,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “Everything in NASA Science is interconnected, and this year, students from around the world can use NASA’s powerful data sets to help us build the ultimate interplanetary survival guide – supporting the science that will enable astronauts to thrive on the Moon and, eventually, Mars, while also inspiring ideas that improve everyday life on Earth and in space for the benefit of all.”

Supporting lunar exploration, Artemis planning

NASA continues to advance plans for a sustained human presence on the Moon through the Artemis program and Moon Base. Several of this year’s Space Apps challenges relate to analytical tools, operational considerations, and human‑system needs relevant to lunar missions. These include work related to surface operations at the Moon’s South Pole, the management of environmental constraints such as sunlight and communications windows, as well as approaches for evaluating the logistical and scientific demands of long‑duration lunar stays. Broader system‑level modeling challenges, such as those that simulate outpost operations or consider astronaut health and safety, mirror the complexity of planning for human activity on the lunar surface.

Strengthening readiness for Mars, deep space

NASA’s exploration strategy includes continued robotic exploration of the outer solar system and preparing for future human missions to Mars. Several challenges involve operational concepts for Martian surface activities, integrating data from multiple Mars missions, or reflecting the mission‑design trade‑offs required for deep‑space exploration. Others address fundamental concerns for long‑duration travel, such as monitoring physiological and behavioral health indicators, or examining how engineering and scientific choices shape mission execution in environments far from Earth.

Some of these challenges also align with NASA’s broader exploration portfolio, which includes ongoing work on future missions to destinations such as Jupiter’s moon Europa and Saturn’s moon Titan. By simulating mission‑design decisions or evaluating environmental analogs on Earth, certain challenges offer frameworks related to how NASA prepares for complex operational scenarios throughout the solar system.

Enhancing access to astrophysics

NASA’s astrophysics missions contribute to understanding the structure and history of the universe. In 2026, this includes active missions like Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx), which is conducting a full‑sky spectral survey, as well as the continued development and deployment of observatories designed to investigate cosmic evolution and exoplanet, which are planets outside our solar system, populations.

Challenges associated with these efforts focus on improving public access to mission data, designing tools that help visualize changes in the sky over time, and supporting broader engagement with the scientific products derived from these missions.

Broader impact across NASA’s mission landscape

Together, these challenges illustrate how NASA’s open data ecosystem enables gold standard science, by freely offering such a wide breadth of information and research. By engaging with the Space Apps event, the entire nation can interact with the kind of real‑world needs defined by the agency.

Registration is available at the NASA Space Apps Challenge. Participants can join in one of 500+ local events, join a team, and select the challenge that they are most interested in addressing during the November hackathon.

Rigorous Analysis Confirms NASA’s Artemis II Heat Shield Performance 

NASA’s Artemis II mission sent four astronauts around the Moon and brought them safely back to Earth, laying a foundation for crewed flights to the Moon’s surface.

Additional engineering data analysis of the Orion spacecraft’s heat shield confirmed initial data showing the heat shield performed as expected.  

In particular, NASA measured whether the thermal protection system effectively safeguarded the crew and Orion systems as the spacecraft reentered Earth’s atmosphere. This test flight was the first time astronauts flew aboard Orion. 

Orion reached a maximum velocity of 39 times the speed of sound and experienced external temperatures exceeding 4,000 degrees Fahrenheit at its peak, all while the four astronauts inside Orion stayed relatively cool with a cabin temperature in the mid-70 degree Fahrenheit range during their return to Earth from the Moon.  

After NASA’s thorough analysis of Artemis I heat shield findings, informed by extensive arc jet material testing at NASA’s Ames Research Center in California’s Silicon Valley, the agency modified Orion’s reentry trajectory for Artemis II by shortening the maximum downrange distance the spacecraft could fly between when it entered Earth’s atmosphere and splashed down in the Pacific Ocean. Analysis prior to the mission showed that limiting downrange distance would limit how long the spacecraft’s heat shield spent in the temperature range at which the Artemis I heat shield phenomenon occurred.  

The spacecraft reentered with precision, entering within only 192 feet of its targeted entry interface, and successfully splashed down only 0.59 miles from the predicted landing site off the coast of San Diego. Initial inspections of the thermal protection system, including diver imagery of the spacecraft’s heat shield taken just after splashdown and further inspections on the recovery ship, found it performed as expected, with a significant reduction in the amount of cracks and char loss as compared to Artemis I.  

Upon the spacecraft’s return to NASA’s Kennedy Space Center in Florida after the Moon mission, thermal protection system experts began additional examination of the heat shield, made of 186 unique blocks of an ablative material called Avcoat. The heat shield was then transported to NASA’s Marshall Space Flight Center in Huntsville, Alabama, where work on sample extraction and internal x-ray scans began in August to provide further engineering insight into the system and behavior of the material.

A thorough post-flight assessment review found that Orion’s aerodynamic and aerothermal performance, including the heat shield and backshell thermal protection system, was in line with engineering predictions based on pre-flight analyses and ground testing. The shorter allowable down range during entry reduced the cracking and char loss experienced on the Artemis II heat shield relative to the Artemis I heat shield by a factor of ten, proving the effectiveness of the trajectory modification. Engineers found only nine spots of char loss of varying sizes on the Artemis II heat shield dish, compared to 103 during Artemis I. 

The analysis also showed that Orion’s robust heat shield design showed consistency from Artemis I to Artemis II, evident by the performance of system features such as the seams between the heat shield Avcoat blocks and the Avcoat surrounding the heat shield compression pad separation bolts. 

Post-flight inspection of Orion’s backshell, the protective cover on the sloped sides of the crew module made up of 1,300 ceramic tiles, showed expected performance across the crew module surface. Visual inspections indicated backshell features designed to seal and protect penetrations such as windows, vents, thrusters, and the side hatch also met expectations, with no signs of overheating observed. 

The team also performed post-flight laser scans of the heat shield surface and is comparing this data to pre-flight measurements to determine material recession, which will then be compared to analysis predictions. Engineers are continuing with heat shield sample extraction at NASA Marshall and subsequent material test and assessment and thermal analysis, to support long-term heat shield development, manufacturing efforts, and data capture. 

Orion’s performance and the team’s analysis on Artemis II reflect system robustness, capability to support crew, and critical insights gathered that will enhance the Artemis III mission and beyond. Following the extensive Artemis I heat shield investigation, upgrades were made to the heat shield design for Artemis III to achieve uniformity and consistent permeability of the Avcoat blocks. Technicians attached the heat shield for the Artemis III Orion crew module at NASA Kennedy in early July, and the Orion crew and service modules were joined at the end of July. The spacecraft has since been successfully powered up for the first time, enabling engineers to check all connection lines between the two modules are working as planned.

NASA continues to advance toward Artemis III as teams ready the Orion spacecraft for next year’s mission in low Earth orbit. NASA will launch the SLS (Space Launch System) rocket and Orion spacecraft with NASA astronauts Randy Bresnik, Frank Rubio, Andre Douglas, and ESA (European Space Agency) Luca Parmitano, to rendezvous with human lander test articles from Blue Origin and SpaceX to demonstrate critical systems and operations needed for future lunar landings, beginning with Artemis IV in 2028.
