How Did I Get Here?

I can remember being drawn to natural science and science in general at an early age. Sure, I was like most kids and watched Tom and Jerry, Bugs Bunny, Today’s Special and many other children’s programming. I think my first *real* exposure to science was from Mr. Rogers Neighborhood, where he would visit other people and their jobs. He taught from the get-go that learning was a good thing and to never be afraid to ask questions. I was always asking questions about how things worked I would…

ISS at Night

http://player.vimeo.com/video/45878034

This is a fantastic video! Stunning beauty that only a select few will ever get to see, at least at this moment in time. Hurtling around the Earth at 17,500mph (nearly 5 miles per second), gazing down upon the Auroras and looking out into the Milky Way Galaxy.

Humans are barraged with centrisms their entire life, but when one understands the true scale of things, all of those centrisms…

Team NASA

Many Americans have a favorite sports team; teams for whom they cheer when they take on rivals. When a group of people congregate to root on their favorite football team, say in a local pub, the energy involved and the sense of camaraderie experienced can be spine-chilling. Even if the sports team loses, the sense of connection remains and is still indescribable; through ups and downs all leading up to the point to where your team has either succeed or they have not.

This is how I see…

What's Wrong with this Picture?

The distribution of funds through the US government needs a change, and fast. NASA currently runs on just half-a-penny on the dollar from the tax payers. Look at what we can accomplish with that pitiful amount and think about what WILL be possible if that amount was raised to just a penny. The only limiting factor with what’s possible is the amount of money funneled into NASA; it has been said that for every dollar you invest into space exploration you get back ten. Sounds like a worth-while…

Gaining Perspective

When we grow up we’re typically told the facts about the world around us without ever really getting involved with discovering for ourselves. I remember looking through a book on planets and space complete with illustrations and pictures of various celestial objects when I was young and being fascinated. But again, everything was learned facts and some were expected to be regurgitated on tests later on. While this is just the style of accepted education, it is far less superior to actual…

Welcome to McMurdo!!

Greetings fellow astrobiology enthusiasts!

My name is Britney Schmidt.  I'm a 30-year-old planetary scientist/geophysicist/astrobiologist, whatever you want to call me by, but basically, I'm obsessed with ice.  That might sound strange, but it's a fascinating substance, and it's the most abundant form of water in the universe, so for those of us who are inspired by the search for life in the solar system…

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

This paper greatly extends the possibility of what a Goldilocks zone can be.  Its no longer the Goldilocks zone as a single expanse, its the Goldilocks zones for a particular area

¿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…
