February 9


February is one of the driest months of the year in northern Colombia’s Córdoba department, a major farming and cattle region. It’s the time of year when farmers normally prepare fields for planting and ranchers move livestock to graze in drying floodplains. In 2026, however, unusually heavy rains in early February upended seasonal rhythms and submerged much of the department under floodwaters.

The OLI (Operational Land Imager) on Landsat 9 captured this false-color image (bands 7-5-4) of flooding along the Sinú River on February 9, 2026 (right). Dark floodwaters cover farmland, pastureland, and several communities, particularly to the west of the river. To the east, water levels at a complex of wetlands are unseasonably high. Lorica, a city of roughly 90,000 people, is visible in the upper part of the image. The OLI image on the left shows the same area on January 23, before floodwaters arrived.

After an already wet January, rainfall intensified in early February when an unusual cold front in the Caribbean pushed south on February 1 and 2, forcing moisture-laden air into northern Colombia and over the Andes. This led to several days of intense downpours in Córdoba, with some areas receiving more than 4 to 7 centimeters (2 to 3 inches) of rain per day, according to one analysis of the event.

NASA’s IMERG (Integrated Multi-satellite Retrievals for Global Precipitation Measurement) estimated rain rates of 1.7 centimeters per hour near Lorica on February 1, the day of the heaviest rains. In the following weeks, storms continued to drench the region. On February 25, imagery from NASA’s Terra satellite indicated that flooding remained widespread.

The floods have been far-reaching and destructive. More than 80 percent of Córdoba flooded, according to the UN Office for the Coordination of Humanitarian Affairs. Preliminary estimates cited by news and government sources suggest that thousands of homes were destroyed, more than 11,000 families displaced, and more than 150,000 hectares of farmland inundated.

NASA’s Aerospace Safety Advisory Panel Releases 2025 Annual Report 

2026-02-25 22:27

The Aerospace Safety Advisory Panel (ASAP), which advises NASA and Congress on safety, has released its 2025 annual report on NASA’s performance and challenges.  

While the panel acknowledged NASA’s safety achievements, it warned that the agency’s biggest challenges stem from interconnected factors – workforce, acquisition, technical authority, budgets, and the growing complexity of human spaceflight – requiring sustained attention as missions become more ambitious.

“Independent assessments like this will make NASA better,” said NASA Administrator Jared Isaacman. “The panel’s report underscores areas where we must raise the bar, from how we structure oversight and manage integrated risk to how we declare and learn from anomalies. We are wholly committed to transparency. That’s how we protect crews, earn trust, and keep the Artemis lunar campaign and our transition to a commercial presence in low Earth orbit on a safe, sustainable path.” 

This year’s report focused on the following topics: 

  • strategic vision and governance 
  • Moon to Mars program 
  • future U.S. presence in low Earth orbit 
  • health and medical risks in human spaceflight 
  • NASA’s X-59 Low-Boom Flight Demonstrator 

The panel noted progress on Artemis II readiness and improved oversight through the Moon to Mars Program Office, as well as safe International Space Station operations, advances in astronaut health research, and the first flight of the X-59 Low-Boom Demonstrator. At the same time, it flagged significant challenges, including Artemis III’s high-risk posture, lessons from Boeing’s Starliner test, space station deorbit planning, and systemic concerns. 

To respond to these new challenges, the panel recommends NASA: 

  • Realign its governance of acquisition strategies for human spaceflight-related capabilities agencywide. 
  • Re-examine the mission objectives and system architecture for Artemis III and subsequent missions to establish a more balanced approach to risk.  
  • Require timely declaration of mishap or high-visibility close call. 

“We were already on the path to implementing change and this report only adds more urgency,” added Isaacman. “That means recalibrating our acquisition strategy — including a build versus buy versus service procurement approach — restoring core competencies through initiatives like converting contractors to civil servant roles and increasing our launch cadence. We’re also aligning our long-term vision for the agency and industry to guide priorities. This includes clarifying our plans for the Artemis architecture moving forward and accelerating proposals for human landing systems to preserve schedule margin. We’ve already shown what transparency and now accountability looks like — through the Boeing Starliner Program Investigation Team report, we owned our mistakes, classified the mission as a Type A mishap, and launched corrective actions to ensure they never happen again. These steps, along with addressing health and medical risk documentation and overhauling and accelerating programs like X-59, reflect our commitment to live up to the expectations of the world’s most accomplished space agency.”  

On Feb. 19, Isaacman held a news conference to present the agency’s findings from the Starliner Crewed Flight Test. Earlier this month, he outlined a new workforce plan to strengthen NASA’s core competencies in technical, engineering, and operational excellence. The agency also is working with both its human landing system industry providers to streamline and accelerate America’s return to the surface of the Moon by 2028. 

“The panel commends NASA for its impressive efforts in 2025 to strategically enhance the agency’s risk management posture despite turbulence in the agency’s organizational environment,” said retired U.S. Air Force Lt. Gen. Susan J. Helms, chair of ASAP. “We very sincerely thank NASA’s leaders and workforce for their passionate dedication to space exploration and their unwavering commitment to the safe pursuit of the nation’s lofty aims to the great benefit of the future of humanity.”  

The annual report is based on the panel’s 2025 fact-finding and quarterly public meetings; direct observations of NASA operations and decision-making; discussions with NASA management, employees, and contractors; and the panel members’ experiences.  

Congress established the panel in 1968 to provide advice and make recommendations to the NASA administrator on safety matters after the 1967 Apollo 1 fire claimed the lives of three American astronauts.

Listen to This Month’s ‘Planetary Parade’ With NASA’s Chandra

Three new Chandra sonifications of data of Jupiter, Saturn, and Uranus have been released. Planets and other Solar System bodies can reflect X-rays given off by the Sun, which Chandra can detect. Sonification is a process that translates data captured by Chandra and other telescopes into sound. In addition to X-rays from Chandra, these new sonifications contain data from Hubble, Cassini, and Keck telescopes. In this image, the amount of diffuse X-rays from a donut-shaped ring of energetic particles around Jupiter, seen on the left and right side of the planet, has been enhanced compared to the amount of X-rays from the planet's auroras, seen at the poles. As the scan moves left to right, it encounters X-rays that bracket the planet on either side, and this plays as woodwind sounds. As we pass over the planet itself, seen in an infrared image from NASA’s Hubble Space Telescope, the sounds become fuller as the infrared data is represented by other instruments. Since Jupiter is tilted slightly, the pitch descends as the scan passes over the bright band near the equator and through the Great Red Spot. On the other side, more X-ray data from Chandra flanks the planet and can be heard as gusty wind sounds at the end.

In late February, people in the Northern Hemisphere can look up for a special sight: six planets will all be visible from clear and dark night skies. New sonifications from NASA’s Chandra X-ray Observatory released Feb. 25 will help commemorate this latest “planetary parade.”

Because the planets in our solar system travel around the Sun in the same plane (known as the ecliptic), they will sometimes appear bunched together in the sky when their orbits find them on the same side of the Sun at the same time. When this happens, it looks like the planets have roughly formed a line from our vantage point on Earth.

In Chandra’s sonifications, which translate astronomical data into sound, three of the planets that will be on display – Jupiter, Saturn, and Uranus – can be seen and heard in ways that they cannot from Earth.

While Chandra is best known for its X-ray insight into black holes and other extreme objects, the telescope has also played an important role in the exploration of our solar system. The Sun gives off X-rays that travel out into the solar system and can be reflected by planets, moons, and other bodies. This gives astronomers a unique window into certain physics that cannot be discovered through other kinds of telescopes.

The sonification of Jupiter combines X-ray data from Chandra with an infrared image from NASA’s Hubble Space Telescope. Woodwind sounds reveal Chandra’s X-ray data, including emission from the planet’s auroras. More instruments join in to represent the planet’s complex cloud layers. Next, through the combination of an optical image from NASA’s Cassini mission and X-rays from Chandra, listeners can experience Saturn like never before. A siren-like sound follows the arc of the rings, and different tones of synthesizers play as the scan passes the planet itself. Finally, listeners can hear the ice giant Uranus through the data collected by Chandra and the W.M. Keck Observatory. The data in this sonification reflects the amount of light detected from the planet and the orientation of its ring.

The process of creating a sonification preserves the integrity of the data, which arrives on Earth as a series of ones and zeroes (binary code), and shifts it into a form that can be processed through hearing. Sonifications expand options for people to explore what telescopes discover in space, an example of NASA’s ongoing commitment to share its data as widely as possible.

Jupiter

In this image, the amount of diffuse X-rays from a donut-shaped ring of energetic particles around Jupiter, seen on the left and right side of the planet, has been enhanced compared to the amount of X-rays from the planet's auroras, seen at the poles. As the scan moves left to right, it encounters X-rays that bracket the planet on either side, and this plays as woodwind sounds. As we pass over the planet itself, seen in an infrared image from NASA’s Hubble Space Telescope, the sounds become fuller as the infrared data is represented by other instruments. Since Jupiter is tilted slightly, the pitch descends as the scan passes over the bright band near the equator and through the Great Red Spot. On the other side, more X-ray data from Chandra flanks the planet and can be heard as gusty wind sounds at the end.

Saturn

The scan of Saturn begins on the right and moves to the left. As it encounters Saturn’s famous rings, seen in an optical image from the Cassini mission, listeners hear a siren effect whose frequency follows the arc of the rings. Once the scan reaches the planet itself, the sounds change, to lower tones with a dark synthetic bass sound. This distinguishes the rings from the planet. Chandra’s X-rays are heard as higher synthetic tones that mark where high-energy activity is found across the planet, rings, and poles.

Uranus

Returning to the left to right scan, the sounds begin with a cello that traces the arcing ring – not as famous as Saturn’s but still prominent – around the ice giant Uranus. The notes change to represent the amount of reflected light and its location on Uranus as seen in an optical light image from the W.M. Keck Observatory. The X-rays detected by Chandra, which come from X-rays from the Sun that are reflected, are heard as higher frequencies as the scan passes over the pinkish region of the planet. The apparent asymmetry in the X-rays may not be a real effect because of the faint signal and the smoothing that was applied to the image.

Visual Description

This release features three sonifications, each focusing on a different planet in our solar system. The sonifications are presented as soundtracks to short videos. Each video features a composite image and an activation line. As the activation line sweeps across the image, it encounters visual elements. These elements are translated into sound, or sonified, according to parameters established by Chandra’s sonification team.

The first sonification focuses on the planet Jupiter. At the center of the associated composite image is the gas giant itself; a seemingly perfect sphere with an atmosphere of latitudinal bands. The bands are different shades of grey, brown, and black, each with its own texture and width. Flanking Jupiter are neon pink and white clouds, representing X-rays from energetic particles in a ring around the planet. In the video, the activation line moves from our left to right. It first encounters a pink cloud, triggering whooshing woodwinds. When the activation line encounters Jupiter, dramatic low notes are triggered. Listen for the dip as the line passes over the Great Red Spot in Jupiter’s southern hemisphere. The activation line continues toward our right, passing more pink X-ray clouds. The largest cloud, the last one encountered, has a bright white core, which translates to loud gusty woodwinds.

The second sonification focuses on the ringed planet, Saturn. In the composite image, the large gas giant fills the frame, its spherical outer layer a pale sandy grey. In this image, the wide bands of rings surrounding the planet are in shades of pale grey and sandy yellow. Here, Saturn is tilted away from us, making the round rings appear oval in shape. Dotting the planet are small pockets of neon blue. These represent reflected X-ray light observed by Chandra. In this video, the activation line moves from our right to left. When the line passes over the rings, a whooshing sounds spreads, conveying the widening middle of the oval shapes. Pockets of neon blue X-ray light trigger synthesizer sounds, with the pitch mapped to each pocket’s vertical position in the image. When the line sweeps across Saturn’s large round body, a low rumbling synth tone is triggered. The volume is linked to brightness, such that the low tone fades when the line reaches the shady side of the planet, on our left.

The third sonification features the planet Uranus. In the composite image, the icy giant is a greenish-blue cyan color, with a blush of neon pink X-rays hovering over its core. Uranus has a collection of very narrow rings, much finer than the wide disk-like rings surrounding Saturn. In this image, the fine rings are near vertical and slightly tilted, creating an oval shape with rounded points at our lower left and upper right. In this sonification, the activation line moves from our left to right. Brightness is mapped to volume and height is mapped to pitch, such that brighter objects at the top of the image sound louder and higher. Here, the curved oval shape of the rings is conveyed as a swooping cello note, with the pitch sliding up as the activation line passes the oval tilted toward our upper right.

Certain nutrients critical for human health lack the shelf life needed to span multi-year missions to the Moon, Mars, and beyond. NASA’s BioNutrients-3 is part of an experiment series testing ways to use microorganisms to produce these nutrients in space and on demand.

The on-demand nature of this experiment is similar to making nutrient-dense fermented foods on Earth, such as how milk is transformed by good bacteria into yogurt. But in this case, there is a focus on producing specific types and quantities of nutrients essential for future space explorers.

Samples from BioNutrients-3, along with other valuable experiments, are set to return from the International Space Station aboard a SpaceX Dragon spacecraft supporting the company’s 33rd commercial resupply mission for NASA. The spacecraft is set to depart the space station on Thursday, Feb. 26 for its return to Earth. Watch NASA’s live coverage of the undocking and departure starting at 11:45 a.m. EST on NASA+Amazon Prime, and the agency’s YouTube channel.

Once the samples return to Earth, the science team at NASA’s Ames Research Center in California’s Silicon Valley will perform analysis procedures. Results from this study can help NASA develop methods to produce vital nutrients that could support human deep space exploration as part of NASA’s Artemis campaign.

NASA’s BioNutrients-3 is part of the Synthetic Biology project, which is funded by the Game Changing Development program within NASA’s Space Technology Mission Directorate.
