—CNBC: “SpaceX Rival Launches Rocket in Historic First, Says Industry is ‘Desperate’ For More”

German rocket maker Isar Aerospace successfully reached orbit for the first time over the weekend, marking a milestone for Europe’s commercial space industry as the company looks to ramp up launches to meet what it says is booming demand. The Munich-based company’s Spectrum rocket reached orbit on Saturday and successfully deployed its payloads in low Earth orbit, an achievement that came on only its second test flight. Chief Commercial Officer Stella Guillen told CNBC on Monday that the company was now focused on scaling production, saying the space industry was “desperate” for additional launch capacity and that Isar had a pipeline worth more than 10 billion euros ($11.6 billion).

—Royal Astronomical Society: “‘Fingerprints’ Inside the Sun Could Reveal If It Once Swallowed a Planet“

It is thought the Sun may have engulfed a super-Earth-sized planet early in its history. Now a new study has gone a step further by suggesting that such an event may have left behind detectable clues inside our star which could still be visible today. This idea of a measurable signature or ‘fingerprints’ in the present-day solar interior was explored by research published today in Monthly Notices of the Royal Astronomical Society. Professor Mutlu Yildiz, of Ege University in Turkey, said: “Our new study suggests that a planet several times more massive than Earth may have fallen into the young Sun and left a lasting chemical imprint deep inside it.

—Physics World: “Moon’s Water Reserves Insufficient to Sustain a Lunar City, Astronomers Find“

Some countries and even wealthy individuals are setting their sights on the Moon with ambitious plans to create a lunar colony. That would require a lot of resources launched from Earth, but how much water and power would be required to keep a lunar city going?…Even assuming one billion tonnes of water on the Moon, if nothing was recycled then a city of a million would last only a few years while a population of 100 000 would run for 20 years before running dry. Even when recycling the water with an efficiency of 98% – as performed on the International Space Station – a city of a million would only have enough water for around a century.

—Ars Technica: “Wary of Artemis IV Timeline, NASA is Changing Lunar Spacesuit Design”

NASA has decided to use a simpler spacesuit for its initial missions to the lunar surface, Ars has learned. The agency announced the decision during an internal meeting this week as it seeks to accelerate its program to land humans at the south pole of the Moon as early as 2028. At the direction of Artemis Program Manager Jeremy Parsons, NASA will work with Axiom Space to develop a “Sortie Suit” variant of the planned spacesuit for the lunar surface. Sources said the Sortie Suit will be used for the initial landing missions flown on landers developed both by SpaceX and Blue Origin. Among the goals of the initiative are to lower the mass of the spacesuit, reduce its complexity, and simplify interfaces between the spacesuits and lunar landers.

—Wired: “Astronomers Have Completed the Largest Map of Space. Yes, You Can Play With It.“

The driving force behind our universe’s accelerated expansion remains one of the greatest mysteries in astronomy. While this force, which scientists refer to as dark energy, pervades our universe, we know almost nothing about it. Located on a remote mountain in Arizona’s Sonoran Desert, the Dark Energy Spectroscopic Instrument (DESI) has spent the past five years mapping the cosmos with the goal of unraveling this mystery. The result is the largest three-dimensional map of the universe ever created. And now—with the release of the latest version of the DESI Legacy Imaging Surveys, a free online tool for exploring the vast imaging data—you too can poke around the universe.

—Phys.org: “New Solar System Models Show Earth is No Fluke“

Over the past three decades, computer models of planetary system formation have gone from fairly crude representations to sophisticated simulations using thousands of different starting points. A paper presented at the Origins 2026 conference in Paris details innovative simulations of how our solar system might have formed without making assumptions about the planetary architecture with which we are so familiar. In his paper, Nader Haghighipour, a planetary scientist at the University of Hawaii in Manoa, argued that his models, unlike previous models, incorporate many completely random starting points and, in turn, let physics drive the models’ ultimate evolution. As a result, these new models are much more complete and allow physics to dictate their outcomes.

—Space.com: “SpaceX, NASA Delay Next Astronaut Launch to ISS Due To Leak on Dragon Spacecraft”

SpaceX’s next astronaut mission to the International Space Station won’t launch on Sept. 12 after all. That flight, known as Crew-13, has been delayed due to an oxidizer leak in the propulsion system of SpaceX’s Dragon spacecraft, NASA announced on Saturday (Aug. 29). Joint NASA and SpaceX teams are performing additional tests and data review and will complete any necessary rework prior to launch,” NASA officials wrote in an update on Saturday. “A new target date will be announced once available.”

—Earth.com: “Giant Black Holes Appeared Too soon After the Big Bang, and Astronomers May Know Why“

Nearly every large galaxy keeps a giant black hole at its center. Some of those giants already weighed a billion Suns when the universe was less than 700 million years old. Astronomers have struggled for decades to explain how anything grew that heavy that fast. A new study built on James Webb Space Telescope observations suggests one possible answer. The researchers describe a young black hole wrapped in gas so dense that the whole object shines like a single enormous star. Astronomers call objects like it black hole stars. The light from this one has been traveling for 13 billion years, since a moment just 660 million years after the Big Bang, and no earlier example has been found.

—Caltech: “Thermal Anomaly Discovered Below Mars’s South Pole“

Based on gravitational measurements that give clues to the Red Planet’s interior structure, Mars’s interior southern hemisphere is around 200 to 400 degrees Celsius warmer than the northern half of the planet and partially molten. The surprising finding adds additional context to Martian history and the periods of time in which it may have hosted conditions favorable for life. The research was led by Caltech alumnus Alexander Berne (PhD ’26), who is now a postdoctoral associate at the University of Arizona. The findings are reported in a paper appearing in the journal Nature on August 27.

—Universe Today: “The CosmoCube Satellite Will Listen to the Early Universe From the Far Side of the Moon”

Multiple space agencies are gearing up to send missions to the Moon in the near future…For one thing, the far side of the Moon is “radio-quiet,” meaning that it is not subject to radio interference from terrestrial sources. This makes the environment the perfect place to conduct radio astronomy research, including the new CosmoCube satellite currently under development at the University of Cambridge. Using the Moon as a natural shield, this satellite will listen for faint whispers (the 21-centimeter line) emitted by hydrogen atoms that existed between the Big Bang and the period known as “Cosmic Dawn.”

—Science Daily: “Trump to Award Congressional Space Medal of Honor to Artemis II Astronauts“

President Donald J. Trump will present the Congressional Space Medal of Honor to each member of NASA’s Artemis II crew during a ceremony at Johnson Space Center in Houston. The event is scheduled for 11 a.m. EDT on Friday, Aug. 28. The medal is one of the highest honors associated with human spaceflight in the United States. It recognizes astronauts whose achievements have made an exceptional contribution to the nation’s space program.

—Scientific American: “China Delays Ambitious Chang’e 7 Moon Mission until 2027“

China’s lunar ambitions took a hit after the country called off the launch of a spacecraft that it has aimed to make the first to ever land on the moon’s south pole. Chang’e 7 was supposed to launch onboard a Long March 5 rocket on August 24, but the launch was scrubbed on Sunday evening, China’s Manned Space Agency (CMSA) said in a statement. Poor weather conditions linked to Typhoon Narra were likely a factor. As a result, the mission will be put on ice until at least 2027.

—ZME Science: “NASA Finally Figured Out What’s Up With Those “Mars Spiders”“

For years, satellites around Mars kept finding mysterious, spider-like geological structures. Mars spiders, scientifically known as araneiform terrain, are unique geological formations predominantly found in the southern hemisphere of Mars. They appear as branching, spider-like channels etched into the Martian surface, sometimes spanning over a kilometer in length. In 2024, NASA-led lab experiments pinned down the likeliest way these “spiders” form: seasonal CO₂ ice. Now, a 2026 follow-up showed that the soil beneath the ice can make or break the process, and that these structures could hold clues to Mars’ wet past.

—Earth.com News: “Why Do Astronauts Get Constipated in Space? Scientists Have a New Clue“

Astronauts have complained about constipation for as long as people have flown to space. Nobody could say exactly why. Researchers have long suspected that living without gravity changes how quickly food moves through the gut. Blood drawn from crew members on long stays aboard the International Space Station now points to an answer. Giorgia La Barbera, a joint first author of the study and an associate professor at the University of Copenhagen’s Department of Nutrition, Exercise and Sports, led the work with NASA. “We see changes in astronauts’ blood samples that indicate that the gut bacteria begin to ferment protein to a greater extent than usual within weeks after the astronauts arrive in space, and this change continues until they are back on Earth,” La Barbera said.

—CNN: “Chinese Rocket Carrying Satellite Explodes Seconds After Launch“

A Chinese rocket set to launch a satellite into orbit blew-up seconds after liftoff Monday, marking the relatively rare failure for a rocket considered a workhorse of Beijing’s space program. The Long March 7A rocket erupted into a massive fireball just 85 seconds after blasting off from the Wenchang Space Launch Site on the island of Hainan on Monday night, video showed. Unlike other successful launches, the incident appears to have been downplayed on China’s state media with scant mention of the explosion.
