NASA Celebrates Artemis II During Houston Texans Space City Day
2026-01-07 22:40
NASA’s Johnson Space Center was front and center Jan. 4, 2026, as the Houston Texans faced the Indianapolis Colts during Space City Day at NRG Stadium. Fans watched the Texans win while getting a close look at NASA’s Artemis II mission, the first crewed flight of the Artemis campaign.
The Artemis II mission will send four astronauts—NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with CSA (Canadian Space Agency) astronaut Jeremy Hansen—around the Moon and back to Earth to test Orion spacecraft systems in deep space and help lay the groundwork for future lunar missions.
NASA connected fans with the agency’s next giant leap, reinforcing Space City’s role in shaping the future of human exploration.
Before kickoff, 27 Johnson employees helped unfurl the U.S. flag for the national anthem, marking the start of an evening that blended football, exploration, and Houston pride.
On the BULLevard, Johnson employees engaged with fans at a NASA activation area, where visitors explored the agency’s Mobile Exhibit Trailer and learned more about Artemis II. Team members answered questions and shared how NASA is preparing to send humans back to the Moon.
Johnson Director Vanessa Wyche and NASA astronaut Jessica Watkins visited the exhibit and the Extravehicular Activity and Human Surface Mobility Program booth, where they greeted team members and thanked volunteers supporting the event.
The International Space Station Program joined the celebration with a prerecorded message from the Expedition 74 crew, marking over 25 years of continuous human presence in low Earth orbit.
“Even from 250 miles above the Earth, we’re proud to represent Houston and celebrate the mission of this incredible city on and off the field,” said NASA astronaut Mike Fincke.
“Today’s game reminds us how connected Houston, NASA, and the Texans truly are,” said NASA astronaut Zena Cardman.
Cardman highlighted how research aboard the International Space Station has led to innovations that benefit life on Earth, including applications now used in sports and athletic safety. Advances in materials developed for spacesuits and astronaut protection have influenced the design of modern helmets and padding, while cooling technologies originally created for extreme environments are used in training gear and protective equipment.
“Space innovation doesn’t remain in orbit, sometimes it ends up on the 50-yard line.”
Jessica Watkins took the field for the Texans’ “Reppin’ H-Town” appearance, joined by Johnson employees Tessa Rundle and Daniel Kolodziejcyk wearing NASA’s Orion Crew Survival System spacesuits. The bright orange pressure suits are designed to protect astronauts during launch, flight, and reentry aboard NASA’s Orion spacecraft.
The pregame continued with Center Director Vanessa Wyche joining the festivities on the field and participating in the ceremonial coin toss, where she called heads.
About 30 seconds into halftime, the Artemis Fueling the Fire video played on the stadium jumbotron, sharing NASA’s plans to return humans to the Moon and marking a major step in the agency’s Moon to Mars campaign.
The video led into a live interview with Vanessa Wyche and Jessica Watkins, where Wyche discussed the Artemis II mission and Watkins highlighted similarities between astronaut training and football training. At the conclusion of the interview, the host invited fans to take part in NASA’s “Send Your Name with Artemis II” initiative, which allows the public to have their names stored on a small chip aboard the Orion spacecraft during the mission. Participants receive a digital boarding pass and virtual guest access to select NASA launches. While the names remain stored electronically inside the spacecraft, the effort symbolically gives participants a place on Orion’s journey around the Moon.
25 Years in Orbit: Science, Innovation, and the Future of Exploration
2026-01-07 21:05
NASA and its partners have supported humans continuously living and working in space since November 2000. A truly global endeavor, the International Space Station has been visited by more than 290 people from 26 countries and a variety of international and commercial spacecraft. The unique microgravity laboratory has hosted more than 4,000 experiments from over 5,000 researchers from 110 countries. The space station also is facilitating the growth of a commercial market in low Earth orbit for research, technology development, and crew and cargo transportation.
After a quarter of century of human presence in orbit, the station remains a symbol of international cooperation and a proving ground for humanity’s next giant leaps to the Moon and, eventually, Mars.
The microgravity environments aboard the space station unlocks discoveries that benefit life on Earth and prepare humans for deep space missions. NASA’s Human Research Program (HRP) works to understand the changes astronauts face aboard the orbital outpost and to develop interventions to keep crews healthy before, during, and after flight.
Astronauts aboard the station exercise for roughly two hours a day to protect bone density, muscle strength, and the cardiovascular system, but the longer they are in microgravity, the harder it can be for the brain and body to readapt to gravity’s pull. After months in orbit, returning astronauts often describe Earth as heavy, loud, and strangely still. Some reacclimate within days, while other astronauts take longer to fully recover.
Through HRP-led studies, scientists track these changes and test solutions—from improved exercise regimens to medical monitoring and nutritional strategies. The results inspire new medical technologies, while teaching scientists how the human body adapts to long-duration spaceflights—knowledge that helps keep astronauts healthy on future missions.
The space station continues to be a critical platform for sharpening skills, technology, and understanding that will prepare humanity to return to the Moon with NASA’s Artemis campaign and journey on to Mars and beyond.
Since space presents an entirely new physical environment with a distinct set of challenges, the orbiting laboratory is uniquely positioned to support research and preparations not possible on Earth. That includes:
- Mastering techniques for basic tasks like drinking water, sleeping, exercising, and handling various materials.
- Developing solutions to microgravity-induced changes to and challenges for the human body.
- Testing reliable technologies and self-sustaining ecosystems necessary for deep space travel, from life support systems to in-orbit agriculture and 3D printing of materials.
- Refining techniques and procedures for data and imagery collection and analysis.
Read more about how the space station has enabled significant strides in our journey farther into the final frontier.
The first decade of the space station was the decade of construction. The second decade moved from initial studies to fully using the orbiting laboratory. Now we are in the decade of results.
With nearly 25 years of experiments conducted aboard the station, more breakthroughs are materializing than ever before. These scientific discoveries and technological advancements are benefiting humanity on the ground, contributing to the growing low Earth orbit economy, and helping to prepare for future exploration of the Moon and Mars.
Innovations include:
- Advances in X-ray technologies, developed to create a space station telescope, are helping unravel the mysteries of our universe while improving medical devices on Earth.
- Temperature-change data that has been employed in efforts to reduce heat absorbed by city surfaces, reduce fire risk, and help farmers efficiently water their fields.
- Demonstrations of robotic technologies with the potential to relieve repetitive movement and other workplace-related stressors.
- Development of a small ultrasound unit for crew health monitoring that has since been adapted to provide diagnostic care in remote areas on Earth.

Algae Swirls Across a South African Reservoir
2026-01-07 05:00
On clear days in Hartbeespoort, South Africa, satellite images often reveal a reservoir with shades of deep blue interrupted by drifting patches of vivid green. These shifting features indicate algae blooms, which can affect water quality, ecosystems, and nearby human communities.
In this animation, from June 2022 to July 2023, an algal bloom grows, moves around the reservoir, and then fades. The animation is composed of images from Harmonized Landsat and Sentinel-2 (HLS), a NASA product that combines imagery from the NASA/USGS Landsat 8 and Landsat 9 satellites and the European Space Agency’s Sentinel-2A, 2B, and 2C satellites.
Algae is an umbrella term for photosynthetic organisms that live in water, encompassing everything from single-celled cyanobacteria to seaweed. They play a vital role in maintaining healthy ecosystems. But when colonies of algae spread too widely or release harmful toxins, they can threaten the very environments they support. These colonies are known as harmful algal blooms, or HABs.
Some HABs are toxic and often are part of a process called eutrophication. Eutrophication begins when there are too many nutrients in an ecosystem—because of agricultural runoff and other inputs—leading to a rapid growth of algae.
“It’s like having a garden,” said Bridget Seegers, a NASA scientist who studies cyanobacteria in freshwater ecosystems. “If you add a lot of nutrients, you’re going to have a lot of growth.”
Eventually, the algae die off. As decomposers break down the dead algae, they consume oxygen, which can lead to hypoxia and the formation of dead zones.
Such conditions have been documented at the Hartbeespoortdam (Hartbeespoort Dam) reservoir, located about 25 kilometers (16 miles) west of Pretoria and used primarily for recreation and irrigation. The reservoir is home to regular harmful algal blooms containing cyanobacteria. It also hosts large mats of invasive water hyacinths. While hyacinths do not produce toxins, they do contribute to eutrophication when they die and decompose.
Harmful algal blooms can affect ecosystem health and human lives and livelihoods. In April 2023, South African authorities linked a large fish kill in Hartbeespoort to low oxygen levels caused by excessive algal growth. More broadly, HABs in drinking water reservoirs can reduce water availability and raise water treatment costs, while swimming in HAB-infested waters can cause rashes, and pets or livestock that drink it may fall ill or die.
One 2022 paper published in Remote Sensing examined algae in the reservoir from 1980 to 2020 using Landsat data. “This is a reservoir that has always been monitored heavily by the local department of water resources,” said Adam Ali, the lead author of the paper. The research used satellite data to provide a big-picture view of conditions across the entire reservoir over long time scales. Using 40 years of Landsat data, the researchers found that the biggest drivers of algal growth were total phosphorus content—a nutrient found in runoff—and water temperature, with blooms typically expanding in the warm summer months and subsiding in the winter.
They also identified key trends over space and time. Algal productivity was higher near Krokodilrivier (Crocodile River) inflows and in the western part of the reservoir due to golf course runoff and restricted water circulation, demonstrating how HABs are influenced by runoff and river inputs. Large blooms occurred between 1982 and 1986, when total phosphorus levels were high. A bioremediation program in the late 1980s succeeded in limiting algae growth, but after funding ended in the late 1990s, harmful algal blooms spiked again in the early 2000s.
To track algae from space, the researchers analyzed the water’s color by measuring different wavelengths of light. From this, they estimated the concentration of chlorophyll-a, a common pigment in algae, and used these values to approximate algae biomass over time. Although water samples remain necessary to confirm that a bloom is harmful, satellite data can help scientists understand the drivers of harmful algal blooms, especially in remote regions where regular ground monitoring is expensive and time intensive.
New and forthcoming NASA missions promise to advance space-based water quality monitoring. The next Landsat satellite is expected to measure wavelengths specifically designed to detect HABs. NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission, launched in 2024, collects data in hundreds of precise wavelength bands in the visible spectrum, which can help scientists identify the type of algae that comprise a certain bloom—a key factor in determining toxicity. Given PACE’s spatial resolution, the data is most useful in coastal areas or larger inland water bodies. Ali is working with researchers at NASA Ames to integrate PACE into future studies.

Supernova Remnant Video From NASA’s Chandra Is Decades in Making
2026-01-06 21:30
A new video shows the evolution of Kepler’s Supernova Remnant using data from NASA’s Chandra X-ray Observatory captured over more than two and a half decades.
Kepler’s Supernova Remnant, named after the German astronomer Johannes Kepler, was first spotted in the night sky in 1604. Today, astronomers know that a white dwarf star exploded when it exceeded a critical mass, after pulling material from a companion star, or merging with another white dwarf. This kind of supernova is known as a Type Ia, and scientists use it to measure the expansion of the universe.
Supernova remnants, the debris fields left behind after a stellar explosion, often glow strongly in X-ray light because the material has been heated to millions of degrees from the blast. The remnant is located in our galaxy, about 17,000 light-years from Earth, allowing Chandra to make detailed images of the debris and how it changes with time. This latest video includes its X-ray data from 2000, 2004, 2006, 2014, and 2025. This makes it the longest-spanning video that Chandra has ever released, enabled by Chandra’s longevity.
“The plot of Kepler’s story is just now beginning to unfold,” said Jessye Gassel, a graduate student at George Mason University in Virginia, who led the work. “It’s remarkable that we can watch as these remains from this shattered star crash into material already thrown out into space.” Gassel presented the new Chandra video and the associated research at the 247th meeting of the American Astronomical Society in Phoenix.
The researchers used the video to show that the fastest parts of the remnant are traveling at about 13.8 million miles per hour (2% of the speed of light), moving toward the bottom of the image. Meanwhile, the slowest parts are traveling toward the top at about 4 million miles per hour (0.5% of the speed of light). This large difference in speed is because the gas that the remnant is plowing into toward the top of the image is denser than the gas toward the bottom. This gives scientists information about the environments into which this star exploded.
“Supernova explosions and the elements they hurl into space are the lifeblood of new stars and planets,” said Brian Williams of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and principal investigator of the new Chandra observations of Kepler. “Understanding exactly how they behave is crucial to knowing our cosmic history.”
The team also examined the widths of the rims forming the blast wave of the explosion. The blast wave is the leading edge of the explosion and the first to encounter material outside of the star. By measuring how wide it is and how fast it is traveling, astronomers glean more information about both the explosion of the star and its surroundings.
NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

Visual Description
This release features a ten second silent video of Kepler’s expanding Supernova Remnant, located in our own galaxy, about 17,000 light-years from Earth. The video was created using X-ray data gathered in 2000, 2004, 2006, 2014, and 2025. Those distinct datasets were turned into highly-detailed visuals, creating a 25-year timelapse-style video of the growing remnant.
Kepler’s Supernova Remnant was once a white dwarf star that exploded when it exceeded its critical mass. Here, in X-ray light, the remnant resembles a cloudy neon blue ring with a diagonal cross line stretching from our upper right down to our lower left. The ring appears thinner and wispier at the bottom, with a band of white arching across the top.
As the video plays, cycling through the 5 datasets, the ring subtly, but clearly, expands, like a slowly inflating balloon. In the video, this sequence is replayed several times with dates included at our lower right, to give sighted learners time to absorb the visual information. Upon close inspection, researchers have determined that the bottom of the remnant is expanding fastest; about 13.8 million miles per hour, or 2% of the speed of light. The top of the ring appears to be expanding the slowest; about 4 million miles per hour, or 0.5% of the speed of light. The large difference in speed is because the gas that the remnant is plowing into towards the top of the image is denser than the gas towards the bottom.
Collecting and interpreting this data over decades has provided information about the environment into which the white dwarf star exploded, and has helped scientists understand how remnants change with time.
