Planet Mars: A Slice of Polar Layer Cake | NASA's Mars Reconnaissance Orbiter

Planet Mars: A Slice of Polar Layer Cake | NASA's Mars Reconnaissance Orbiter

The Martian ice cap is like a cake with every layer telling a story. In this case, the story is one of climate change on Mars. In this image is an exposed section of the north polar layered deposits (NPLD). Like a delicious slice of layered tiramisu, the NPLD is made up of water-ice and dust particles stacked one on top of the other. However, instead of icing, layers are topped with seasonal carbon dioxide frost. We can observe lingering frost adhering to one of the layers.

The high-resolution and color capabilities of the High Resolution Imaging Science Experiment (HiRISE) provide details on the variations in the layers. Scientists are also using radar data. This show us that they have continuity in the subsurface. During deposition, these complex layers might encapsulate tiny air pockets from the atmosphere that, if sampled, could be studied to understand linkages to previous climates.

In the end, it is not always a piece of cake studying NPLD on Mars but, where there is cake, there is hope!

This HiRISE camera image was captured by NASA's Mars Reconnaissance Orbiter (MRO) at an altitude of 319 kilometers (198 miles).

The University of Arizona, in Tucson, operates the High Resolution Imaging Science Experiment. It was built by BAE Systems in Boulder, Colorado. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate (SMD), Washington.

Lunar Science: Mountains of The Moon | NASA's Lunar Reconnaissance Orbiter

Lunar Science: Mountains of The Moon | NASA's Lunar Reconnaissance Orbiter

Most mountains on the Earth are formed as plates collide and the crust buckles. Not so for the Moon, where mountains are formed as a result of impacts. Images taken looking across the landscape rather than straight down really bring out topography and help us visualize the lunar landscape. However such images can only be taken as the spacecraft rolls to the side, in this case about 70°, so the opportunities are limited. Foreground is about 15 km wide, view is northeast across the north rim of Cabeus Crater.

Panoramic view looking across the North rim of Cabeus Crater from the SW. The distance from left to right is about 75-km and from foreground to background in the center is about 50-km. The U.S. Lunar Crater Observation and Sensing Satellite (LCROSS) impact on October 9, 2009, was just off the bottom center of the panorama.

Cabeus Crater is relatively old, 100 km in diameter, and contains significant areas of permanent shadow. Such regions are of great interest because they may harbor significant deposits of ices (water, methane, etc). Cabeus Crater is most famous as the site of the U.S. Lunar Crater Observation and Sensing Satellite (LCROSS) Centaur rocket upper stage impact (October 9, 2009) that was intended to excavate and eject any volatiles that may be in the regolith (what we call the lunar soil). Though analyses of data collected during the impact are still ongoing, preliminary results suggest that yes, significant amounts of water ice may be trapped in these shadowed regions (at least at this one spot).

Cabeus is a lunar impact crater that is located about 100 km (62 mi) from the south pole of the Moon. At this location the crater is seen obliquely from Earth, and it is almost perpetually in deep shadow due to lack of sunlight. Hence, not much detail can be seen of this crater, even from orbit. Through a telescope, this crater appears near the southern limb of the Moon, to the west of the crater Malapert and to the south-southwest of Newton.

Two and a half days after the LCROSS impact the LRO spacecraft slewed 70° back towards Cabeus Crater to allow the  Lunar Reconnaissance Orbiter Camera (LROC) to acquire an overview image of a portion of the northern rim. The large mountain (or massif) in the right background is a portion of the ancient rim of the South Pole-Aitken basin, it rises some 6000 meters (19,685 feet) above the surrounding plains, and more than 9200 meters (30,184 feet) above the floor of Cabeus Crater—taller than any mountain on the Earth. On the Moon mountains are formed in only minutes as huge amounts of energy are released when asteroids and comets slam into the surface at velocities greater than 16 km per second (more than ten times faster than a speeding bullet). In contrast, mountains on the Earth typically form over millions of years during slow-motion collisions of tectonic plates.

Future astronauts will see the same view as they descend to the surface for a polar landing. Explore the rim of Cabeus on your own as you plan your landing spot!

Shenzhou-20 Crew Completes a Wide Variety of Tasks | China Space Station

Shenzhou-20 Crew Completes a Wide Variety of Tasks | China Space Station

The Shenzhou-20 crew aboard China's Tiangong space station conducted an assortment of scientific experiments and tests last week, according to the China Manned Space Agency (CMSA). China launched the cargo spacecraft Tianzhou-9 on July 15, 2025, and it successfully delivered supplies for its orbiting Tiangong space station.

Tianzhou-9 is loaded with essential supplies, totaling approximately 6.5 tonnes, including consumables for the orbiting crew, propellant, and equipment for application experiments and tests. This is the largest amount of cargo sent to the space station since Tianzhou-6.

After receiving the equipment and supplies, the Shenzhou-20 crew conducted various experiments, research tasks, and tests.

In the field of aerospace medicine, the crew transported cell experiment units to the human system research cabinet to carry out relevant experiments, and completed manual observation of sample images, sample recovery and preservation, plus other related tasks.

This research not only contributes to the study of the impact of long-term space flights on astronauts' physical functions, but it also relates to general health issues of people back on Earth.

In the field of space life science and biotechnology, multiple scientific experiments have been carried out using the biotechnology experiment cabinet, including the study of the influence and mechanism of the microgravity environment in space on the migration of skeletal muscle precursor cells, and research on the biological functions of nucleic acid lipid nanocarriers in the microgravity environment. The obtained data will help expand researchers' understanding of the physiology and pathology of organisms, and provide fundamental support for human health concerns.

Additionally, during the past week, the Shenzhou-20 crew carried out musculoskeletal research experiments by collecting foot pressure and joint kinematics data during running and resistance exercises under a range of load conditions during flight, and obtained the mapping relationship between exercise state parameters and foot pressure.

Furthermore, astronauts used equipment to complete sliding tests and obtained data for studying the variation laws and cognitive mechanisms of fine motor control under microgravity conditions.

In the field of microgravity physical science, the crew, in accordance with the scientific experiment arrangement of microgravity combustion, completed the replacement of the sampling cover of the gas experiment plug-in, along with the setting and restoration of the state of exhaust gas emission, and other tasks.

Finally, the Shenzhou-20 crew completed assignments that included equipment inspection and maintenance of the regenerative life support system, environmental monitoring within the station, transfer of cargo packages and material organization, routine medical examinations and weightlessness protection exercises.

Nebula NGC 2020: A Stellar Nursery in Neighboring LMC Galaxy | Hubble

Nebula NGC 2020: A Stellar Nursery in Neighboring LMC Galaxy | Hubble

This panorama features the nebula NGC 2020 in the constellation Dorado. It forms part of a vast star-forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, approximately 163,000 light-years away. NGC 2020 is an HII Region surrounding the Wolf-Rayet star BAT99-59. HII regions are vast areas of ionized hydrogen in space, crucial for star formation and the study of the universe. 

Wolf–Rayet stars, often abbreviated as WR stars, are a rare heterogeneous set of stars with unusual spectra showing prominent broad emission lines of ionized helium and highly ionized nitrogen or carbon. The spectra indicate very high surface enhancement of heavy elements, depletion of hydrogen, and strong stellar winds. The surface temperatures of known Wolf–Rayet stars range from 20,000 K to around 210,000 K, hotter than almost all other kinds of stars.

Image Processor Judy Schmidt: "My own processing of the recent Hubble anniversary image of NGC2020. FITS mosaic was assembled by the OPO team at STScI. Tried to keep the brightness and saturation to a moderate level to keep it easy on the eyes."

"When I gaze at Earth from the ISS, I’m always overwhelmed by the massive scale of atmospheric circulation."

"Recalling the weather knowledge I studied during my pilot days, it’s fun to imagine the movements of the troposphere’s atmosphere while thinking things like (a front is forming over there) 😃" —T. Onishi, May 11, 2025

I can’t help but take photos of the clouds.  

A few days ago, I saw a cloud that looked like a flower.  

The weekend on the ISS is almost over.  

This might be the last weekend I can take it easy.  

Wishing everyone a great weekend too.

—T. Onishi, July 26, 2025

"Cumulonimbus clouds lined up (probably)."

—T. Onishi, July 20, 2025

"If I had woken up at 5:20 this morning, it would have been a perfect orbit passing beautifully over Japan, but I woke up at 8."

"Giving up on photos of Japan, here’s another photo instead."

"A huge cluster of clouds ☁️"

"It’s hard to gauge the altitude, but I think they might be cumulus clouds.

If anyone knows more, please let me know 🙇‍♂️"

"Since I had to work a substitute shift earlier this month, I’m getting a three-day weekend this week. Wishing everyone a great weekend too♪"

—T. Onishi, May 24, 2025

Last year, I visited the Canary Islands for ESA's PANGAEA training.

The airflow was disturbed by the islands, and it was visualized as swirling in the wake of the islands.

—T. Onishi, June 7, 2025

"One more weather topic."

"The low-pressure systems familiar from weather forecasts—did you know that the way their spirals rotate is opposite in the Northern and Southern Hemispheres?"

"This is because of something called the 'Coriolis force,' which acts in opposite directions depending on whether you're north or south of the equator."

"The first photo shows the spiral of a low-pressure system as seen in Japan. 🌀" —T. Onishi, May 11, 2025 

"Good morning 😃"

"The ISS, living in the Greenwich Mean Time zone, has just passed 8:30 AM."

"The photo shows Canada’s Manicouagan Crater, glowing under the sunlight."

"Its size, clearly visible to the naked eye even from here, speaks to the magnitude of the impact back then."

"Wishing everyone a wonderful weekend."

—T. Onishi, May 31, 2025

Astrophotographer Rui Santos: "The night sky and planetary alignment featured . . . was captured from Pinhal de Leiria, Portugal. I decided to view the alignment from here because I knew I'd have a clear view of the horizon. Since the planets were stretched out across the sky, I had to do a panorama and try to avoid light pollution (lower left and lower right) from surrounding cities and towns. Venus, Jupiter, Mars and Uranus are included above, but because I wasn't able to arrive as the Sun was setting, Saturn, Neptune and Mercury aren't in the frame."

"At bottom center is the Crastinha Lookout Point, one of several watchtowers in the Forest of Leiria. The building to its right is the reconstruction of what used to be the guard's house, dating from 1883. This tower is still in use today."

Portugal, officially the Portuguese Republic, is a country on the Iberian Peninsula in Southwestern Europe. Featuring the westernmost point in continental Europe, Portugal borders Spain to its north and east—sharing the longest uninterrupted border in the European Union; to the south and the west is the North Atlantic Ocean.

Rare Intermediate-sized Black Hole Found Eating a Star | NASA Hubble & Chandra

Rare Intermediate-sized Black Hole Found Eating a Star | NASA Hubble & Chandra

NASA’s Hubble Space Telescope and NASA’s Chandra X-ray Observatory have teamed up to identify a new possible example of a rare class of black holes. Called NGC 6099 HLX-1, this bright X-ray source seems to reside in a compact star cluster in a giant elliptical galaxy. This discovery shows how space telescopes working together across wavelengths can unveil the complete story of these cosmic phenomena, helping us understand the full spectrum of black holes shaping our universe.

NASA's Chandra X-ray Observatory is being canceled in NASA's Fiscal Year 2026 Budget Request, along with 18 other active science missions. NASA's science budget is being reduced by nearly 50%.

Contact your representatives in the United States Congress, House and Senate, to express your concerns about severe science budget cuts at NASA: https://www.usa.gov/elected-officials/

NASA's Fiscal Year 2026 Budget Request

https://www.nasa.gov/fy-2026-budget-request/

NGC 6099 is a elliptical galaxy in the Hercules constellation. It is located close to the celestial equator and is partly visible from Earth's southern and northern hemispheres at certain times of year.

Just a few years after its 1990 launch, Hubble discovered that galaxies throughout the universe can contain supermassive black holes at their centers weighing millions or billions of times the mass of our Sun. In addition, galaxies also contain as many as millions of small black holes weighing less than 100 times the mass of the Sun. These form when massive stars reach the end of their lives.

Far more elusive are intermediate-mass black holes (IMBHs), weighing between a few hundred to a few 100,000 times the mass of our Sun. This not-too-big, not-too-small category of black holes is often invisible to us because IMBHs do not gobble as much gas and stars as the supermassive ones, which would emit powerful radiation. They have to be caught in the act of foraging in order to be found. When they occasionally devour a hapless bypassing star—in what astronomers call a tidal disruption event—they pour out a gusher of radiation.

The newest probable IMBH, caught snacking in telescope data, is located on the galaxy NGC 6099’s outskirts at approximately 40,000 light-years from the galaxy’s center, as described in a new study in the Astrophysical Journal. The galaxy is located about 450 million light-years away in the constellation Hercules.

The Crepuscular Rays of Galaxy IC 5063 in Indus | Hubble

The Crepuscular Rays of Galaxy IC 5063 in Indus | Hubble

Many of the most stunning views of our sky occur at sunset, when sunlight pierces the clouds, creating a mixture of bright and dark rays formed by the clouds’ shadows and the beams of light scattered by the Earth's atmosphere. These are called crepuscular rays. Astronomers studying the nearby galaxy IC 5063 are tantalized by a similar effect in this image from the NASA/European Space Agency Hubble Space Telescope. Here, a collection of narrow bright rays and dark shadows is seen beaming out of the blazingly bright center of the active galaxy, shooting across at least 36,000 light-years. IC 5063 resides 156 million light-years from Earth.

Astronomers have traced the rays back to the galaxy’s core, the location of an active supermassive black hole. The black hole is feeding on infalling material, producing a powerful gusher of light from superheated gas near it. Although the researchers have developed several plausible theories for the lightshow, the most intriguing idea suggests that the shadows are being cast into space by an inner tube-shaped ring, or torus, of dusty material surrounding the black hole.

Image Processor Judy Schmidt: "Revisiting our old friend IC 5063, this time with a bit of color, clearly revealing the emission line features emerging nearly perpendicular from the crepuscular rays. These features, in cyan, are most easily viewed zoomed in on the nucleus. They are thought to be formed by the actively accreting supermassive black hole in the center of the galaxy. In this case, the black hole may have a dark 'donut' of dust around its equatorial axis, and the extremely bright light creates ionizing cones and jets of material out of the polar axis."

"The processing here is not only extreme, but also a combination of data from two separate HST snapshot proposals, and the wondrous Legacy Survey DR9 release. I used my hacky Photoshop subtraction model to clearly reveal the center of the galaxy in the Hubble data, while the outer parts are partially filled using the LS DR9 imagery, more smoothly and confidently illustrating the galaxy's outer tidal structures."

Globular Cluster Omega Centauri: Over Ten Million Stars

Globular Cluster Omega Centauri: Over Ten Million Stars

Globular star cluster Omega Centauri, also known as NGC 5139, is 15,000 light-years away. The cluster is packed with about 10 million stars much older than the Sun within a volume about 150 light-years in diameter. It is the largest and brightest of 200 or so known globular clusters that roam the halo of our Milky Way galaxy. Though most star clusters consist of stars with the same age and composition, the enigmatic Omega Cen exhibits the presence of different stellar populations with a spread of ages and chemical abundances. In fact, Omega Cen may be the remnant core of a small galaxy merging with the Milky Way. With a yellowish hue, Omega Centauri's red giant stars are easy to pick out in this sharp, color telescopic view. A two-decade-long exploration of the dense star cluster with the Hubble Space Telescope has revealed evidence for a massive black hole near the center of Omega Centauri.

France-UK MicroCarb Earth Science Mission Launch | Arianespace Vega C Rocket

France-UK MicroCarb Earth Science Mission Launch | Arianespace Vega C Rocket

On Friday July 25th, 2025, at 11:03 p.m. local time (02:03 a.m. UTC, 04:03 a.m. CEST, on July 26th, 2025), Arianespace successfully launched the MicroCarb satellite for French space agency, CNES. This launch mission, called “VV27” was performed using an Arianespace operated Vega C rocket, launched from Europe's Spaceport in French Guiana.

The auxiliary passenger, MicroCarb, was placed in a Sun-synchronous orbit at an altitude of 650 km and separated 1 hour and 41 minutes after lift-off. It is Europe’s first mission to monitor and map atmospheric carbon dioxide.

The CNES' MicroCarb mission is designed to map sources and sinks of carbon dioxide (CO₂), the most important greenhouse gas, on a global scale. The satellite's dispersive spectrometer instrument will measure atmospheric concentration of CO₂ globally with a high degree of precision. MicroCarb's platform is based out of the lastest CNES Myriade model. Its instrument was built by Airbus Defence and Space, and the integration was realized by Thales Alenia Space UK through a dedicated partnership implemented with the UK Space Agency.

MicroCarb is a joint mission between the UK Space Agency and French Space Agency, Centre National d’Études Spatiales (CNES), serving as the prime contractor. The mission is co-financed by these two agencies, as well as by the European Commission and the French government within the framework of the Investments for the Future Program (PIA), managed by the National Research Agency (ANR). The satellite is designed to precisely map atmospheric carbon dioxide (CO₂), capturing detailed data on emissions from human activities as well as absorption by natural sinks such as oceans and forests.

The satellite is built on the CNES Myriade platform. Thales Alenia Space, a joint venture between Thales (67%) and Leonardo (33%), completed the assembly, integration, and testing of the satellite platform at RAL Space in Harwell, UK, and was responsible for launch preparations. Airbus Defence and Space provided the instrument payload, the infrared spectrometer.

MicroCarb will operate in low Earth orbit, at an altitude of 650 km, and serves as a precursor to the European Union’s Copernicus Anthropogenic Carbon Dioxide Monitoring (CO2M) mission—a constellation of three satellites, with payloads supplied by Thales Alenia Space, which will deliver precise measurements for human-induced atmospheric carbon dioxide and methane. MicroCarb complements the CO2M mission by providing early observations and valuable data, enhancing our capability for CO₂ and methane monitoring to inform climate policy makers. 

Additionally, a special city-scanning mode will enable the mapping of CO₂ distribution within urban areas.

The Changing Surface of Mars | NASA's Mars Reconnaissance Orbiter

The Changing Surface of Mars | NASA's Mars Reconnaissance Orbiter

The High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Oribter (MRO) commonly takes images of recent craters on Mars that are usually found by the MRO Context Camera where they disturb surface dust. An impact site in this area was first imaged in December 2017.

Dust has since eroded from the surface, probably due to the planet-encircling dust storm back in 2018. The dark spots around the fresh craters have vanished because they only affected the dust that has since disappeared.

This HiRISE image was captured by NASA's MRO at an altitude of 290 kilometers (180 miles).

The MRO is a spacecraft designed to study the geology and climate of Mars, to provide reconnaissance of future landing sites, and to relay data from surface missions back to Earth. It was launched on August 12, 2005, and reached Mars on March 10, 2006. 

The University of Arizona, in Tucson, operates the High Resolution Imaging Science Experiment (HiRISE). It was built by BAE Systems in Boulder, Colorado. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate (SMD), Washington.

Moon Science: Jackson Crater's Central Peak | NASA's Lunar Reconnaissance Orbiter

Moon Science: Jackson Crater's Central Peak | NASA's Lunar Reconnaissance Orbiter

Central peak Jackson crater seen obliquely

Spectacular contrasts of gray scale in the central peak of Jackson crater signal variations in composition and maturity (degree of freshness of the surface). Image is 3100 meters wide, north is to the right, M1265842750LR

Jackson Crater east-to-west oblique (subsampled)

East-to-west view of Jackson crater (71 kilometers diameter). Image was acquired when LRO was at an altitude of 111 kilometers and the Sun was to the west of the crater (LROC was facing somewhat towards the Sun; phase angle 114 degrees). The central peak rises about 1800 meters above the crater floor and the top of the crater rim in the background has more than 4000 meters relief relative to the floor. Image width is about 64 kilometers and north is to the right, M1265842750LR

Jackson is a prominent lunar impact crater that is located in the northern hemisphere on the far side of the Moon. Less than one crater to the northeast is the crater Mineur, and to the south-southwest lies McMath. This crater created a large ray system. A skirt of higher-albedo material covers the surface within one crater diameter with a slightly darker band along the outer ramparts. Beyond that radius, the rays form wide sections that grow increasingly diffuse and wispy with distance. The largest sections lie in roughly 90° arcs to the northeast and southwest, while a narrower arc projects to the south-southeast. The rays continue for hundreds of kilometers across the surface.

The rim of the crater is well-defined and not significantly worn. The edge is somewhat polygonal in shape, with the southeastern rim being more rounded. The inner walls display some terracing. The interior floor is generally level with some irregularities in the northeastern part. Parts of the floor have a relatively high albedo. Jackson lies to the northwest of the Dirichlet-Jackson Basin.

What is the composition of the crust in Jackson Crater from top to bottom? It is relatively easy to measure the surface, but what lies beneath the surface? On the Earth geologists can dig and drill deep into the crust. We do not have that luxury on the Moon, at least not yet. However, we can take advantage of natural drill holes in the crust—impact craters. When impacts occur they dig into the crust and the central peaks expose the deepest material. Jackson Crater formed on what was rather uneven terrain—to the east of the crater the elevation is about +6000 meters and to the west about +3000 meters. The bottom of the crater sits at +1000 meters, and the material exposed in the central peak comes from more than 1000 meters deeper still. By studying the rocks exposed in the central peak, we can get a glimpse of materials that have come up from five or more kilometers below the surface (>3 miles).

This year, NASA's Lunar Reconnaissance Orbiter (LRO) celebrates its 16th anniversary orbiting the Moon (2009-2026). This mission has given scientists the largest volume of data ever collected by a planetary science mission at NASA. Considering that success and the continuing functionality of the spacecraft and its instruments, NASA awarded the mission an extended mission phase to continue operations. LRO continues to be one of NASA's most valuable tools for advancing lunar science.

Mind/Body Practices for Deep Space Exploration (RelaxPro) | NASA Research

Mind/Body Practices for Deep Space Exploration (RelaxPro) | NASA Research

NASA is conducting research examining the stress of human spaceflight on the body and the mind. There are many human factors to consider as humanity prepares to begin deep space exploration missions. What we learn from spaceflight medicine could transform lives here on Earth.

The psychological well-being of astronauts is becoming just as vital as their physical and technical readiness as space missions extend into deep space. Long-duration missions pose unique challenges, such as isolation, confinement, communication delays, and microgravity. These factors can significantly affect psycholgical health and cognitive performance. Ongoing research is aimed at ensuring astronauts are psychologically and emotionally prepared for the challenges of space.

The Mind/Body Practices for Deep Space Exploration (RelaxPro) investigation aims to test an astronaut relaxation training protocol designed for use in spaceflight. These mind and body practices have previously demonstrated effectiveness in reducing both stress and sleep issues on Earth.
