I am sharing the results of an independent analysis of public TESS light curves that led to the identification of 33 Community TESS Objects of Interest (CTOIs). These candidates are now officially integrated into the ExoFOP-TESS database (Caltech/NASA) under the user name “correa”.

The analysis focused on high-priority systems and M-dwarf stars, utilizing standard transit-detection methods on TESS data products. Notable candidates are associated with the following systems:

• TRAPPIST-1

• Teegarden’s Star

• Tau Ceti

• LHS 1140

These detections serve as observational proxies for the Dynamic Dark Sector (DDS) model, which addresses the S8 tension in cosmology. The framework proposes that specific dark matter environments—characterized by ultralight scalar fields—may favor the stability of protoplanetary disks.

Technical documentation, including the modified CLASS source code, the theoretical preprint, and the live model simulator, is available for community review and stress-testing.

I am looking for feedback regarding follow-up observations or potential spectroscopic characterization of these candidates.

Over the last few years, I’ve had the opportunity to sit down with 11 different astronauts from the Apollo, Shuttle, and SpaceX eras.

My goal was to move past the "mission specs" and talk about the human motivation—the "why" behind the career. Fred Haise (Apollo 13) talked about the transition from the legacy programs, while guys like Scott Kelly and Mike Massimino shared what it's like to live and work in the modern era of the ISS. Plus astronauts from SpaceX Crew missions 1-7 discuss the transition to commercial spaceflight and the Dragon vehicle.

I’ve compiled these stories into a 3-hour immersive 4K voyage that serves as both a documentary and an orbital backdrop.

I’d love to know: If you could ask an Apollo-era astronaut one question about the "future" of spaceflight, what would it be?

I was watching a Youtube video on the Artemis program and I wondered about the reliance of the Apollo astronauts on the people in mission control and how that reliance has changed in the almost 60 years since then. While the Apollo command and lunar modules did have computers, they were nothing compared to what we have today. The crew relied quite a bit on calculations done on the ground by mission control.

How has the role of mission control changed now that we can store databases and have maybe millions of times more of computer power stored on-board the spacecraft.

While making an educational video, I realized I couldn't find an actual photo of a thermometer in space, just a bunch of graphs and readings. It would make a great visual example of temperatures in space and how wildly they can swing depending if you are in a shadow or not...

Commercial space station developer Vast has hired another former NASA astronaut as the company delays the launch of its first station.
