Also I see the link did not work ! (Page not found)
Hello @zainab, sorry about the link! The invite is public but it may still require you to be logged into the forum to view the invite. Otherwise, I’m not sure why it didn’t work. You can also find it by clicking on “AWG Meeting Calendar” on the left side and then clicking on the event title for the Regolith Subgroup meeting event.
I also just added you to the Google calendar invite list so you should have just received an email.

Hello everyone,
Thank you Rachel for holding down the fort while I was in holiday.
First of all, thank you very much for all of your work and dedication towards this project. It has been so much fun and loved all the discussions.
The goal is for each chapter to be ready for submission to publishers as a sample within about a month. After that, we’ll share them with our colleagues for further review, and then proceed to publish the white papers while publishers make their decision regarding the book, for which each chapter will later be expanded. So long story short… almost there, last push before we get a break!
For people that wish to contribute, there is still time. Send me a message and I will put you in contact with the correct chapter lead.
Upcoming meeting will be on October 13th. Similar to last meetings, this will be “office hours”, in case there are questions, or for new members to learn about the project.

Hello everyone. Happy 2026! Can’t wait to see you all in a couple of hours. Today we will be discussing a new potential narrative for mars regolith simulant nutritional content study, a potential collaboration between multiple labs to generate a standardization for plant regolith growth, and status of book.

Team,
Among all the projects we’re currently working on in CR, we recently recovered the XRF blueprint of the construction-mining site next to our lab. The site, called Tajo Zulay, was primarily used for extracting construction materials and is now barely active.
The surrounding area has often been described as resembling the Red Planet, and the machinery there has a history of unusually aggressive wear and destruction of parts. After conducting some research, we found that the site may posses a striking resemblance to Gusev Crater. We are still looking into this 
Notably, Tajo Zulay is exceptionally rich in zeolites, goethite, and hematite. The area began with basaltic or andesitic volcanic rock (typical of Costa Rica’s tectonic setting).

Hello everyone,
For our next Plant Regolith Subgroup meeting, we’ll have a presentation on a recent publication by the first author titled “Comparative analysis of Brassica rapa var. cymosa grown in hydroponic conditions, lunar maria, and lunar highland regolith simulants: biochemical profiling and effects on Drosophila melanogaster as an in vivo model.”
