Drilling: How you do it, and our drilling status on the JOIDES EXP 350

Posted on May 6, 2014 at 4:26pm 0 Comments

When we had our orientation of the ship, we were shuffled along many different parts of the boat and had all these ship terms and drilling terms thrown at us. It was overwhelming, to say the least. I know a lot of the science team felt overwhelmed by the terminology as well! I would imagine a drilling specialist would feel the same way sitting in on a science meeting. Through the kind heart of the Operations Superintendent, Kevin Grigar (whom you’ll meet in a future blog), and others, I’ve got… Continue

Happy Earth Day from the Philippine Sea!

Hey SAGANet friends! 

I hope you all had an excellent Earth Day on April 22nd. Did you all hug a tree, ride a bike or read the Pale Blue Dot monologue by our main man Carl Sagan? I tried to hug a tree, but my arms wouldn’t reach (clearly I’m awesome at jokes). Although I’m really far away from land, being out at sea really felt like I was a part of the 'Blue'…


I'm on a BOAT!... well technically, it's a ship.

Hey SAGANet friends! Julia here, I'm one of your admins and normally I operate out of Denver, Colorado, but currently I find myself on a ship in the Pacific Ocean just under Tokyo, Japan. I’m onboard a drilling ship called the JOIDES Resolution acting as one of two Education Officers on Expedition 350 – Izu-Bonin-Mariana Rear Arc.

Hi Julia,  I'm a small youtuber with a small astrobiology channel. I hope this forum can really beef up my research for videos, and I'd love to reach out to some more experts. Gina suggested I touch base with you and Graham Lau in regards to scicomm. Anyway,  have a great day!

do you have the link to your talk yet?

A virtual book club sounds great. Unfortunately I haven't read the book the discussion is on today, so I probably won't have much to add to the discussion, but I did join so I can be up to date for the next virtual meet up.

Aww damn Im sorry to him. I would have returned it, but I had every intention to catch your talk. However I got stuck in traffic and wasn't able to make it- I wasn't in the city last night so I was trying to drive back today. But yeah please do send me the video.

Julia, this was posted on S.A.G.A.N. by John, you should definitely check it out! It's a great article about Kathryn Denning's work on anthropology and SETI.

Using tried and tested methods of constructing habitats from ethnobotanical and ethnozoological useful species for self sustainability on Mars

Posted by Andrew Planet on June 26, 2020 at 8:00am 0 Comments

To maximize crop yields on Mars it would be advantageous to do away with annuals and biannuals by engineering the latter into perennials as standard. Not only would that entail far less work to grow produce as the act of replanting is made obsolete, but per given cultivated area perennials bring forth more food and materials with less demand from the soil than the equivalent of annuals.

Imagine a superfood annual such as lentils engineered into a lentil tree for which there already…

Radiolysis-powered life

¿Are the Venusian sulphuric acid clouds the by product of long dead anoxogenic photosynthetic organisms?

Posted by Andrew Planet on May 4, 2020 at 2:51pm 2 Comments

I just read the piece at the link below entitled "Study: Life might survive, and thrive, in a hydrogen world."

I'd been thinking on similar lines recently, on different atmospheres with early life, but I was considering anoxogenic bacteria whose byproduct is sulfur instead of molecular oxygen. ¿Had life evolved on Venus could its sulfuric clouds be the signature byproduct of such life with no branches ever evolving to produce the equivalent of Earth's Great…
