“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.
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.”
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.
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.

On this day in 2023, India became the fourth nation to land a spacecraft on the Moon (following the Soviet Union, the U.S., and China). India’s Chandrayaan-3 probe landed at the lunar South Pole, the first spacecraft to land in that region. Chandrayaan-2 had crashed on the Moon’s surface back in 2019, whereas Chandrayaan-1 was a lunar orbiter in 2008.
Measuring the near surface plasma density and how it changes over time.
Measuring the thermal properties of the lunar surface near polar regions.
Measuring the seismic activity around the landing site to deduce the internal structure of the lunar crust and mantle.
As with the US space program, the boost to Indian pride following this successful mission was immeasurable. As one proud Indian noted:
The success of Chandrayaan-3 reverberated through classrooms and homes across India, with countless young eyes glued to screens, witnessing a historic moment. The mission’s success, though grand, is symbolic of more profound implications. With a burgeoning youth population, India stands on the precipice of a new era of innovation. The world’s largest youth demographic resides here, and Chandrayaan-3 has offered them more than just a scientific marvel; it has provided them with a vision of what’s achievable.
The Wisconsin Center for Origins Research (WiCOR) at the University of Wisconsin has two questions as part of its mission:
How do habitable planets form?
How does life emerge on habitable planets?
And now, the center has discovered its first exoplanet that brings up an unexpected question – Why is the newly discovered exoplanet GJ 523b a Mega-Earth rather than a gas giant like Saturn or Jupiter?
This new exoplanet, located about 87 light-years away, is 2.5 times the size of our Earth and 23 times its mass. To date, it was understood that something this large would become the core of a gas giant and not just a rocky planet like Earth. So what is the story here?
The results will appear shortly in a new paper, which will include some theories as to how this happened. You can read more about the discovery and at least one theory at the WiCOR site now.
Most lunar surface conditions are incredibly harsh for microbial survival. High ultraviolet radiation, temperatures, and energetic particle radiation limit survival over most unprotected lunar surfaces, particularly in equatorial regions where all previous crewed exploration occurred. However, whether these harsh conditions are widespread at lunar poles has not been examined considering topographical effects. Here, we show that recent microorganism survivability data and lunar surface remote sensing reveal likely survivable niches in lunar polar regions. Analysis of topography and latitude-driven surface conditions using remote sensing data and high-resolution illumination models indicates the lunar south pole has substantial regions with persistent low temperatures and ultraviolet flux. Comparing these conditions to survivability data of specific microorganisms, we find that significant lunar polar areas likely have surface conditions amenable to microbial survival. Our findings suggest that lunar polar regions may be less hostile to microbial survival than previously assumed. This does not encompass growth likelihood, but survival in a cryptobiotic state where growth would be possible if habitable conditions were present. Potential microbial survivability at lunar poles is particularly significant given many examined microbes will likely be transported to the Moon during crewed lunar south pole exploration planned in numerous near-term missions. Thoughtfully planning exploration and tracking its impact is key to limiting and understanding potential unintended life transfer to the Moon.
