—Spaceflight Now: “Russian Progress cargo ship arrives at International Space Station”

An unpiloted Russian Progress cargo ship arrived at the International Space Station Saturday carrying supplies and equipment for the orbiting outpost. The Progress M-25 docked at the space-facing port of Russia’s Poisk module at 9:44 a.m. EDT (1344 UTC). It circled the station before making its final approach using the automated Kurs rendezvous system. Russian cosmonauts Pyotr Dubrov and Anna Kikina were standing by to take manual control of the approach using remote controls, but everything went smoothly as the craft closed in, 260 miles above the Black Sea. A series of hooks inside the docking mechanism were driven closed to complete the docking operation.

—Science Daily: “Astronomers Just Found the Youngest Known Planet Ever“

Astronomers have confirmed the youngest known planet yet, a world less than 1 million years old that is still surrounded by the gas and dust from which it formed. The planet, called Elias 2-24 b, was identified using observations preserved in NASA-funded archives. It is still orbiting within its young star’s dusty disk, giving scientists a rare opportunity to study planet formation while it is still happening.

—Radio France Internationale: “Europe Weighs the Cost of Sending Its Own Astronauts into Space“

French President Emmanuel Macron wants Europe to develop its own way of sending astronauts into space within a decade. Europe already builds rockets and satellites and sends astronauts to the International Space Station – but it still relies on American spacecraft to get them there. As the global space sector expands, the question is whether Europe should invest in closing that gap, and what it would take to do so.

—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.

—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.

Earlier today, NASA astronaut Anil Menon and Roscosmos cosmonauts Pyotr Dubrov and Anna Kikina left Russia and arrived safely at the International Space Station (ISS).

With their arrival, Expedition 74 will come to a close by month’s end and Expedition 75 will begin.

The Expedition 74 crew currently on the ISS includes NASA astronauts Jessica Meir, Jack Hathaway, and Chris Williams; European Space Agency astronaut Sophie Adenot; and Roscosmos cosmonauts Sergey Kud-Sverchkov, Sergei Mikaev, and Andrey Fedyaev.

Expedition 75 will begin once NASA’s Williams and Roscosmos’s Kud-Sverchkov, and Mikaev depart the station after an eight month mission.

With all of the attention on the Chinese and race to the Moon, it is sometimes easy to forget that Russian cosmonauts have been working together with NASA aboard the ISS for over 25 years. The first crew on the ISS in November 2000 was composed of NASA astronaut William M. Shepherd and Russian cosmonauts Yuri P. Gidzenko and Sergei K. Krikalev (shown below). The three were the Expedition 1 crew, and stayed aboard the station until March 2001.

Here are some recent NASA-related stories of interest.

—Florida Sentinel: “Boeing Starliner Costly But Cheaper for NASA Than SpaceX Switch, Audit Says“

Boeing’ Starliner costs and delays remain the target of the latest audit from NASA’s Office of the Inspector General, but remains a cheaper option for the agency than relying solely on SpaceX for its commercial crew needs. The audit releasedJune 30 dinged the beleaguered spacecraft’s tumultuous and still uncertain path toward certification and wars that the timetable for its use to ferry astronauts to and from the International Space Station is running short.

—Newser: “NASA Chief Defies FAA With ‘High-Risk’ Flight“

NASA chief Jared Isaacman took to the skies over Washington in a vintage fighter jet on July 4, even after federal regulators flagged the plan as too risky. The Federal Aviation Administration rejected a request on June 30 to let four 1970s-era Northrop F-5 Tiger II jets participate in the National Mall flyover for America’s 250th birthday, calling the aircraft “very high-risk” and citing concerns about flight controls, ejection scenarios, and past crashes, the Wall Street Journal reports.

—Benzinga: “NASA’s Jared Isaacman Says Blue Origin’s New Glenn Recovery Is ‘Beyond Impressive’“

NASA Administrator Jared Isaacman said Blue Origin has devoted significant resources to cleaning up and rebuilding its launch pad after a late-May explosion of a New Glenn rocket, as the agency weighs how the setback could affect lunar missions tied to the Artemis program. “Blue Origin’s response to the situation is almost beyond impressive, and that’s not just a NASA assessment,” Isaacman told reporters Wednesday afternoon, according to Ars Technica. He said U.S. Space Force officials also have been deeply involved in Blue Origin’s planning since the May 28 test anomaly damaged New Glenn’s only operational launch pad.
