Here are some recent space-related stories of interest.

—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.

In Case You Missed It/Podcast: The Second Monster in Aliens

Posted on by onespaceman2000

A few months back, NPR’s Planet Money podcast had a terrific episode titled, “The Real Horror of ‘Alien’ and How It Explains Why We’re Not Paid Enough.”

In the episode, we learn more about Weyland-Yutani, the company in the 1979 film Alien that employed the crew on the space tug Nostromo. You may remember that this crew eventually became little more than a meal and incubator for more monsters.

Maybe there was another monster on the ship as well. Maybe it was even a bigger monster, because it had already inflected the entire Earth economy. Something called monopsony, which is basically when all of the workers become the quasi-slaves of a few corporations. Unread contracts and absent labor unions became the basis for much abuse on and off the spaceships.

It’s a fun episode that allows you to see the film from the perspective of an economist as well as an everyday worker.

You can also hear from Fede Álvarez, who directed and co-wrote a subsequent film Alien: Romulus. It will probably be no surprise that Weyland-Yutani doesn’t become a better place to work.

Science fiction is often a mirror on society, even if we don’t see our reflection right away. Think about all of those drug commercials on television where everyone is dancing, yet the announcer keeps telling you about the horrible side-effects and possibility of death. Sometimes you just need to close your eyes and listen. The mirror can work even without your eyes.

Chinese Spying: The Moon Race Just Got Ugly

The US Department of Justice (DOJ) has reported that the Chinese have been hacking into US government agencies since as early as 2018. One of the targets of the Chinese hacker group, known as QTFY, was NASA.

A DOJ press release from earlier today, titled Justice Department and FBI Seize Platforms Operated and Used by China State-Sponsored Hackers to Target U.S. Critical Infrastructure, stated:

Among the victims of QTFY computer intrusion activity are the National Aeronautics and Space Administration, Federal Reserve, Department of Energy, Department of Justice, Department of Health and Human Services, National Institutes of Health, and the U.S. Senate.

At this time, the nature of what was taken from NASA and other government agencies was not provided. However, given the importance of the Artemis mission for both national and commercial purposes, it is not hard to believe that Artemis information was part of the hack.

It may be to NASA’s advantage that it has been operating by the seat of its pants for more than a year now. There was no Artemis strategy to steal. In addition, much of NASA’s work is in the hands of the private sector, so that extra layer of protection may have helped.

It is worth noting that many federal agencies were spending last year fighting off internal hackers from the US Department of Government Efficiency (DOGE), which did great damage across the federal government.

The Chinese efforts have been detected and ended. I am not sure you can say the same thing about DOGE.

Update: NASA Administrator Jared Isaacman has reported that the Chinese hackers were unable to access NASA data.

Space Quote: SpaceX Expanding into Louisiana

“Today is a pivotal moment for Louisiana. This announcement pushes our state beyond $250 billion in new investment and puts us at the center of the next great frontier…We have the people and talent to build what the world once thought impossible, creating jobs on land, across the Gulf and through space. Our job creation knows no bounds. This is America First. This is Louisiana First. I want to thank Elon Musk and the entire SpaceX team for choosing Louisiana.”

–Statement by Louisiana Governor Jeff Landry regarding SpaceX’s announcement to build its fourth space port in the state. The $100 billion investment by SpaceX is expected to create 3,000 new direct jobs as well as 8,100 new indirect jobs. The first launch from the planned site is not expected until 2029.

Space Stories: A Far Side Satellite, Congressional Space Medals, and the Scrubbing of a Chinese Moon Mission

Here are some recent space-related stories of interest.

—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.

Note: No podcast will be available this week. The program was finicky and difficult to edit.
