Our next story swims near Papua New Guinea, an island country in the Pacific Ocean, where researchers have identified a new species of walking shark. Now, walking shark does not mean a shark strolling down the sidewalk in sneakers. These are small sharks that can use their fins to wiggle and push themselves along shallow seafloors. It looks a bit like a careful crawl. The report says scientists identified a new species, which means researchers studied it closely enough to tell that it is different from other known walking sharks. Walking sharks often live in shallow reef areas. In places like that, being able to move across the seafloor can be useful, especially in tight spaces among rocks, coral, or tide-pool-like areas. This discovery is a reminder that the ocean is still full of animals people are only beginning to understand. Even today, scientists can find creatures that are new to science—not because the animal just appeared, but because humans had not officially described it before. So if you love animals, this is a great reminder: careful observing matters. The next big discovery might start with someone noticing, “Hmm, that little shark moves in an unusual way.”

Our first story zooms toward Mercury, the small rocky planet closest to the Sun. A spacecraft mission called BepiColombo has been traveling through the Solar System for years. It is a team project from the European Space Agency, or ESA, and Japan’s space agency, JAXA. On September 3, the mission began what scientists call its Mercury arrival phase. That means BepiColombo is getting ready for the final part of its trip to Mercury. One important step just happened: the mission separated from its transfer module. You can think of the transfer module like a space helper that carried the science spacecraft for much of the long journey. Once its job was done, it was time for the main science orbiters to keep preparing for Mercury. The plan is for two science orbiters to enter orbit around Mercury later in 2026. Orbit means they will travel around the planet again and again, like runners circling a track. Then, in 2027, the orbiters are expected to start studying Mercury closely. Mercury is tiny compared with many planets, but it is a big mystery. It is very close to the Sun, so it can get extremely hot. Scientists want to learn more about its surface, its magnetic field, and how it became the planet we see today. Space missions take careful timing. They cannot just fly wherever they want whenever they want. Teams on Earth plan years ahead, using gravity, engines, and math to guide spacecraft across millions of miles. So this week’s update is not the end of the adventure. It is more like the moment in a story when the explorer reaches the final trail before the treasure map’s big X.

Our next story takes us far north, to a cold Arctic waterway called Nares Strait, between Greenland and Canada. NASA reported that a large iceberg from Greenland’s Petermann Glacier drifted into Nares Strait and bumped into Joe Island. And here is the surprising part: the icy giant kept floating. A huge iceberg is sometimes described as an ice island because it can be so large and flat that it looks like a frozen piece of land. This one came from a glacier, which is a slow-moving river of ice. Over time, pieces of glaciers can break off and become icebergs. Scientists do not have to stand right next to an iceberg to study it. That would be difficult and dangerous. Instead, they can use satellite pictures from above Earth. Satellites can help researchers see where ice is moving, whether it breaks apart, and how Arctic landscapes are changing. When the iceberg ran into Joe Island, it might sound like a crash in a cartoon. But real ice movement can be slow, powerful, and complicated. Scientists study these events carefully because ice, ocean water, wind, and temperature all work together. NASA’s report is a good example of how Earth science can happen from space. A satellite can look down at a place most people will never visit and help scientists ask: Where did this ice come from? Where is it going? How is it changing? So even though the iceberg kept floating, it left scientists with plenty to observe.

Our final story takes us behind the scenes of a very big rocket. NASA said technicians have begun installing four RS-25 engines on the Space Launch System rocket for Artemis III. Artemis III is planned as a mission to help carry astronauts toward the Moon. The Space Launch System, or SLS, is NASA’s powerful Moon rocket. Its engines have an enormous job: helping lift the rocket away from Earth. Installing engines is careful, step-by-step work. Technicians use special tools, cranes, measurements, and lots of teamwork. Think of building a giant rocket a little like assembling the most complicated group project ever. Every part has to fit where it belongs. Every connection needs to be checked. And because astronauts may one day ride on top of this rocket, safety matters at every step. The RS-25 engines are not just big metal tubes. They are highly engineered machines designed to handle extreme heat, pressure, and force. When a rocket launches, fuel and oxygen are used to create a powerful push called thrust. That thrust helps the rocket climb upward, away from Earth’s gravity. NASA’s update does not mean Artemis III is launching today. It means one important piece of preparation is underway. Space missions take a long time to plan because engineers want to test, inspect, and understand as much as they can before launch day. So today’s rocket news is about patience, precision, and the many people who help turn a Moon mission from a plan into a real machine.

Our next story is about space safety, careful planning, and saying goodbye to old spacecraft. The European Space Agency, or ESA, reported updates on Sunday about two of its old Cluster satellites, named Samba and Tango. These satellites were heading toward planned reentries over a remote part of the South Pacific Ocean. A reentry is when an object in space comes back into Earth’s atmosphere. The air high above our planet may seem thin, but when a spacecraft rushes into it very fast, the spacecraft can heat up and break apart. That is one reason space agencies plan these endings carefully, especially over remote ocean areas. Samba and Tango were part of ESA’s Cluster mission, which studied Earth’s magnetic environment. Now that these spacecraft are old, scientists are watching their final trips to learn more about what happens when satellites reenter. That knowledge could help engineers design future spacecraft to be safer and cleaner at the end of their missions. Space is useful for weather forecasts, communication, navigation, and science, but space machines do not last forever. So researchers are asking an important question: how can we be responsible when a mission is done? This story is a good reminder that science is not only about launching new things. It is also about taking care with what we have already sent up.

Our first story looks way, way up. NASA says its Nancy Grace Roman Space Telescope launched from Florida on Sunday and successfully separated from its rocket. That means the telescope made it through an important early step on its trip to space. Roman is built to survey huge areas of the sky. Imagine trying to understand a giant library, not by reading one page at a time, but by taking in whole shelves at once. That is a little like what this telescope is designed to do with the universe. Scientists want Roman to help study some very big mysteries, including dark energy and dark matter. Those names sound spooky, but they are science words for things researchers can see clues about, even though they do not fully understand them yet. Dark matter may help explain how galaxies hold together. Dark energy may help explain why the universe’s expansion is speeding up. Roman will also help scientists look for planets beyond our solar system. Those are called exoplanets. Some orbit stars far, far away, and every new discovery helps scientists learn how many kinds of planets can exist. The telescope is named for Nancy Grace Roman, an important NASA scientist who helped make space telescopes possible. So this launch is not just about one machine. It is about many people, over many years, asking: what else is out there?

Our final story floats above our planet, where the International Space Station circles Earth again and again. NASA said Northrop Grumman’s Cygnus XL cargo craft fired its engines for 20 minutes and 43 seconds to raise the space station’s orbit. That means the cargo ship gave the station a carefully planned push. Why would a space station need a boost? Even though the station is in space, it is not completely free from Earth’s atmosphere. Way up there, the air is extremely thin, but there are still tiny particles that can gently slow the station over time. If mission teams did nothing, the station’s path would slowly get lower. So engineers plan small orbit-raising maneuvers. Think of it like giving a playground swing a gentle push at the right time, except the swing is a giant science lab, the push comes from rocket engines, and everything is happening high above Earth. The Cygnus XL is a cargo craft, which means it can bring supplies and equipment to the station. In this case, it also helped adjust the station’s orbit. NASA reported the engine firing lasted 20 minutes and 43 seconds, which is very precise. In spaceflight, timing matters. The big idea is teamwork. Astronauts, flight controllers, engineers, cargo ships, and computers all help keep the International Space Station safely circling Earth. Sometimes space exploration looks like a rocket launch. And sometimes it looks like a well-timed, twenty-minute push.

Our next story is about a small space mission with a big question: what are planets around other stars like? NASA said its Pandora mission has begun observing exoplanets. Exoplanets are planets outside our solar system. They do not orbit our Sun. Instead, they orbit other stars, which can be many, many light-years away. Pandora is a small satellite, but it has an important job. It watches exoplanets and the stars they travel around. Scientists want to learn more about what exoplanet atmospheres may be like. An atmosphere is the blanket of gases around a planet. Earth’s atmosphere gives us air to breathe and helps shape our weather. Studying an exoplanet atmosphere is tricky because these planets are so far away. Scientists often cannot see them like big bright balls. Instead, they look for tiny changes in starlight. When a planet passes in front of its star from our point of view, a little bit of the star’s light can pass through the planet’s atmosphere. That light may carry clues. Pandora’s work is just beginning, so this is not a story about finding aliens. It is a story about gathering careful clues. Each observation helps scientists ask better questions about the many different kinds of worlds in our galaxy.

Our final story takes us to the Moon’s South Pole, a place with shadowy, icy spots that can stay extremely cold. NASA researchers reported that a few tough microbes from Earth might be able to survive in those cold, shadowed places. Microbes are tiny living things, much too small to see without special tools. They are all around us on Earth: in soil, in water, on surfaces, and even on our skin. This does not mean the Moon is suddenly covered in Earth germs. The report is more careful than that. It suggests that some especially hardy Earth microbes might survive if they were carried there accidentally. That matters because future Moon explorers want to study the Moon’s chemistry and search for clues in icy regions. If Earth microbes get mixed into samples, scientists could have a harder time telling what belongs to the Moon and what came from us. So this discovery is really about planning carefully. Space missions already use clean rooms, special procedures, and lots of engineering to reduce contamination. Contamination means bringing something into a place where it does not belong. The big idea is simple and important: when humans explore, we should be good guests. Whether scientists are studying a forest, an ocean, or the Moon, careful exploring helps protect the clues we are trying to understand.

Our third story takes us to the Moon, where a spacecraft camera spotted a new mark on the surface. NASA’s Lunar Reconnaissance Orbiter photographed a fresh crater after an old Falcon 9 rocket stage hit the Moon on August 5. A rocket stage is a part of a rocket that helped launch something, then separated later. Some old rocket parts continue moving through space for a long time. The Moon is covered in craters, but a fresh crater is especially interesting to scientists. Why? Because when something hits the Moon, it can dig up material from below the surface. That fresh material may look different from the older, dustier ground around it. Scientists can compare before-and-after images. Before: no new crater. After: a new crater and bright-looking disturbed material around it. That helps them learn about the Moon’s surface and about what happens during impacts. This story also helps scientists practice predicting where space objects will land. Space agencies and researchers track many objects in space, from working spacecraft to old rocket pieces. Predicting their paths is like solving a very complicated motion puzzle. This does not mean rocket pieces are falling on the Moon all the time, and it is not a scary story for Earth. The key idea is careful observation. Scientists saw a change, photographed it, and used it as a chance to learn. Here is the BigBrain idea: sometimes a new dot in a picture is not just a dot. It can be evidence. By comparing images over time, scientists can discover what changed and ask why.

Our first story floats about 250 miles above Earth, where the International Space Station circles our planet again and again. NASA said two astronauts were scheduled for a spacewalk on Thursday, August 13, to replace a space-to-ground antenna on the station. That may sound like a small part, but antennas are very important. They help the space station and Mission Control share information, including data and high-speed messages. Think of the station like a science lab flying around Earth. Astronauts do experiments, check equipment, and talk with teams on the ground. To do all that well, the station needs strong communication systems—kind of like how a video call works better when the connection is clear. A spacewalk is when astronauts leave the inside of the station while wearing special spacesuits. Those suits are like tiny personal spacecraft. They give astronauts air to breathe, protect them from the extreme temperatures of space, and help them move safely while they work outside. NASA’s preview described this as a planned upgrade, not an emergency. The goal was to keep the orbiting lab ready to send and receive important information as it travels around Earth. So the big idea is this: space exploration is not only rocket launches and faraway planets. Sometimes it is careful maintenance—tightening, replacing, checking, and upgrading—so people in space and people on Earth can keep working together.

Our final story is about a new space telescope getting ready for a big trip. NASA reported that the Nancy Grace Roman Space Telescope was fueled as teams prepared it for a late-August launch. Fueling is one of the important steps before a spacecraft can leave Earth. It does not mean launch has already happened; it means teams are getting the telescope ready for launch day. The Roman Space Telescope is designed to help scientists study faraway galaxies, planets beyond our solar system, and big mysteries about the universe. Planets beyond our solar system are called exoplanets. They orbit other stars, the way Earth orbits the Sun. Space telescopes are special because they can observe the universe from above much of Earth’s atmosphere. Our atmosphere is wonderful—it gives us air to breathe and helps protect life—but it can also blur or block some kinds of light from space. A telescope in space can collect clues that are harder to see from the ground. Roman is named for Nancy Grace Roman, an astronomer who helped make space telescopes possible. She is often called the “Mother of Hubble” because of her important work supporting the Hubble Space Telescope. When a mission is preparing for launch, engineers move carefully. They test, check, fuel, and re-check. Space missions are complicated, so schedules can change, and teams watch conditions closely. The big idea: before a telescope can help us explore deep space, many people on Earth have to do careful, step-by-step work to get it ready.

Our next story floats outside the International Space Station, where astronauts recently worked in one of the most amazing workplaces imaginable: space. NASA reported that on August 6, astronauts completed a spacewalk to prepare for solar array upgrades on the space station. A spacewalk means astronauts put on special spacesuits and go outside the station while staying safely connected and carefully guided by teams on Earth and inside the station. So why work on solar arrays? Solar arrays are like giant wings covered with panels that collect sunlight. They help turn sunlight into electricity. That electricity powers the lights, computers, experiments, air systems, and many tools astronauts need while living and working in orbit. Think about a solar-powered calculator or a garden light that charges in the Sun. Now imagine that idea made huge, strong, and ready for space. The space station circles Earth again and again, moving in and out of sunlight. When sunlight hits the arrays, the station can gather energy and store some for later. Spacewalks take planning, teamwork, and patience. Astronauts practice tasks before they go outside, use tethers to stay secure, and follow checklists step by step. It is a little like building or fixing something very important—but while floating, wearing a spacesuit, and traveling around Earth. The exciting part is not just that people can work in space. It is that a big orbiting laboratory depends on a simple star-powered idea: sunlight can become electricity.

Our first story zooms to Mars, where a spacecraft just got a clever cosmic push. NASA’s Psyche spacecraft is on a long trip to study a metal-rich asteroid, with arrival planned for 2029. To help it get there, Psyche flew past Mars and used the planet’s gravity like a giant invisible slingshot. Here’s the kid version: imagine rolling a toy car past a spinning merry-go-round. If the timing is just right, the motion can help the car zip away in a new direction with extra speed. In space, planets have gravity, which pulls on spacecraft. Mission teams can plan a path so that a spacecraft swings close to a planet and comes out moving in a helpful new way. That is called a gravity assist. During the Mars flyby, the Psyche team also tested science instruments and captured a time-lapse video. A time-lapse is when pictures taken over time are played quickly, so slow motion looks fast. It can make a planet glide through the view like a movie scene. The big idea is that space travel is not only about blasting rockets. It is also about careful planning, math, timing, and using gravity as a teammate. Mars did not push Psyche with a hand, of course. Its gravity did the work, and the spacecraft’s path was planned so that the pull helped send it onward. So the next time you swing on a playground, think of Psyche: swooping by Mars, borrowing a bit of cosmic motion, and continuing toward an asteroid that could teach scientists more about what rocky worlds are made of.

Our next story swims into the warm waters around Indonesia, where scientists have formally described a small reef fish called a shrimpgoby. This newly described species has bright orange markings and delicate fin filaments. Fin filaments are thin, wispy parts of a fin that can look a little like tiny streamers waving in the water. The fish’s name was inspired by the “Sunrise of Java,” connecting the animal to geography, color, and language. Now, when scientists say they “described” a new species, it does not always mean nobody has ever seen the animal before. It means researchers studied it carefully, compared it with known species, and gave it an official scientific description and name. That name helps scientists around the world talk about the same animal without confusion. A shrimpgoby is a small fish that often lives near the seafloor on reefs. Many gobies are tiny, quick, and good at hiding. Scientists look closely at details like colors, body shape, fin rays, and where the animal lives. This story is also a reminder that our planet is still full of discoveries. Some are not giant dinosaurs or huge whales. Some are small, bright fish with sunrise-colored markings. And the name matters. Java is an island in Indonesia, and connecting a species name to a place can remind us that animals live in real homes, connected to local waters, local people, and local languages. Discovery is not just about finding something new. It is also about paying attention carefully and respectfully to the world that is already there.

Our next story takes us to East Antarctica, one of the coldest places on Earth, where a satellite picture made people say, “Wait… does that look like a hummingbird?” NASA highlighted new radar data from a satellite mission called NISAR. NISAR is a partnership between the United States and India. The satellite’s radar data produced an image of East Antarctica that resembles a hummingbird. Now, to be clear, scientists did not find a giant bird frozen in the ice. This is a pattern in the data that happens to look like a hummingbird—kind of like when you see a cloud shaped like a dragon or a pancake shaped like a heart. Radar is a special way to study things using signals that bounce back. Bats use sound echoes to understand their surroundings. Radar uses radio waves. A radar satellite sends signals down toward Earth, then measures what comes back. That can help scientists learn about ice, land, forests, and other parts of our planet in new detail. Why is Antarctica important to study? Antarctica holds a huge amount of Earth’s ice. Watching it carefully helps scientists understand how ice changes over time. Satellites are helpful because Antarctica is enormous, remote, and very hard for people to explore everywhere on foot. The hummingbird-shaped picture is also a fun reminder: science can be beautiful. Data is not always just numbers in a spreadsheet. Sometimes it becomes a picture that helps humans notice patterns, ask questions, and say, “Whoa, Earth is amazing.”

Our first story kicks off on soccer’s biggest stage: the World Cup final. On Sunday, Spain beat Argentina 1 to 0, and the winning goal came in extra time. Extra time happens when a big knockout game is tied after the usual playing time, so the teams keep going for a little longer to decide a winner. Now, imagine how tired those players must have felt. They had already run, passed, defended, listened to coaches, and tried to stay calm while millions of fans watched. Then, with the game still close, Spain found a way to score. That is a sports moment, but it is also a teamwork moment. A goal in soccer usually is not just one person doing one amazing thing. It often starts with someone winning the ball, another player moving into space, someone making a smart pass, and teammates trusting each other. The World Cup is special because teams and fans come from many countries. People speak different languages, wear different colors, sing different songs, and cheer in different ways. But for a few weeks, they are all watching the same game and wondering: who will lift the trophy? For Argentina, losing a final can feel disappointing. For Spain, winning can feel joyful. And for young athletes watching at home, there is a big lesson either way: practice matters, teamwork matters, and even when the clock gets long and your legs feel tired, staying focused can make a difference.

Our first story looks up—way, way up. Students used a shared telescope project to study light coming from a faraway galaxy. A galaxy is a huge group of stars, gas, dust, and maybe planets, all held together by gravity. When a telescope collects light from a distant galaxy, it is almost like catching a postcard from space. That light has traveled a very long time before reaching the telescope. The report says the students spotted a bright galaxy and studied its light. We do not have extra details about the galaxy’s name, distance, or exactly what they measured, so we should be careful not to guess. But we can say this: classroom science can be real science. Students can ask questions, collect observations, and learn how astronomers use light as evidence. Here’s the BigBrain idea: telescopes do not just make space look bigger. They help us notice patterns—how bright something is, what color its light appears to be, and how it changes over time. Those clues can help scientists learn more about objects that are much too far away to visit.

Our next story is about moon robots practicing teamwork. We are not adding a specific mission or a real breaking-news claim today; we are using the fixture’s idea to explore how robots can learn to work together safely and carefully. Imagine two small robots on a practice course that looks a little like the Moon. The ground is dusty-looking. There are pretend rocks, gentle slopes, and marked paths. One robot might be good at taking pictures. Another might be good at carrying a small tool or checking a path. If they try to do everything alone, they might miss something. But if they share jobs, they can help the team. Robot teamwork takes planning. Engineers may give robots instructions such as: stop before an obstacle, send a message, wait for a partner, or choose a safer route. That sounds simple, but it is a big deal. On the Moon, distances are huge, the ground can be tricky, and help is not just around the corner. Practicing on Earth helps people test ideas before sending machines to difficult places. Here is a kid-sized way to understand it. Think about building a block tower with a friend. One person finds the flat blocks, one person stacks, and both people watch to make sure the tower stays steady. Robots can be planned to do something a little like that: each one has a job, and together they try to be more careful than any one robot alone. Teamwork is not only about going fast. It is about listening, checking, and making safer choices. That is a smart lesson for robots, engineers, and all of us.
