Let's Make Sure Astronauts Won't Extinguish Native Mars Life - To Jupiter's Callisto, Saturn's Titan And Beyond - Op Ed

Let's Make Sure Astronauts Won't Extinguish Native Mars Life - To Jupiter's Callisto, Saturn's Titan And Beyond - Op Ed

Lisa Pratt, the new planetary protection officer for NASA takes up her job at a challenging time for astrobiology. We are approaching a major decision point for Mars. If Elon Musk succeeds in his ambitious plans, then some time in the next couple of decades we may introduce trillions of hardy microbial spores to the planet. Not deliberately, but just because we can't help but take them with us wherever we go.

But not just for astrobiologists.  I think almost anyone would be saddened if we had this headline news story in the 2030s:

Need To Protect Mars From Earth Microbes 'till We Know More - Elon Musk Also Would Not Want To Extinguish Martian Life

Value Of Titan As Base For Humans In Saturn System - Surprisingly - Once There - Easier For Settlement Than Mars Or The Moon

Value Of Titan As Base For Humans In Saturn System - Surprisingly - Once There - Easier For Settlement Than Mars Or The Moon

Titan might seem an unlikely place to for humans to build settlements, and maybe eventually colonize. After all, it is so far from the sun, and extraordinarily cold, and it's a long journey to get there (at present). But actually, if you set aside the difficulty of getting there, which we should overcome as our technology improves - it's got more going for it than you might think. This is an idea originally developed in some detail by Charles Wohlforth and Amanda Hendrix, authors of Beyond Earth: Our Path to a New Home in the Planets

Putin - Doesn't Want Nuclear War - Aims For Peace & Renewed START 2 With Updated Credible Deterrent

Putin - Doesn't Want Nuclear War - Aims For Peace & Renewed START 2 With Updated Credible Deterrent

I’ve had several PM’s and we’ve had comments by scared people in our Doomsday Debunked Facebook group who have read alarmist stories suggesting that Putin threatens to attack the US. If you have read these stories, it is worth listening to his actual speech to get the Russian perspective on it. It could hardly be more different. He presents it as, in his view, the only way to preserve peace.

Why The Moon Is By FAR The Best Place For A Backup - NOT Mars - To Protect And Restore Our Beautiful Earth

Why The Moon Is By FAR The Best Place For A Backup - NOT Mars - To Protect And Restore Our Beautiful Earth

I think we should build our first offworld backup on the Moon. We can start by storing seeds there, similar to the Svalbard seed vault in Norway. Within a few years we should have easy access to the Moon, and then it will be easy to do. The lunar caves are naturally at the right temperature. Add a vacuum sealed packet of dried seeds to a rover that explores a suitable lunar cave, and leave it there at the end of the mission, inside the rover, and that's it.That's the start of a future seed vault. From small beginnings ... Elon Musk says there are two futures, to stay on Earth and eventually go extinct, or to become a "multi-planetary species". He says Mars is our "plan B". But there is a third possibility. 

So You Thought We Could Terraform Mars Quickly? Large Space Habitats Instead Open Solar System To Humans

So You Thought We Could Terraform Mars Quickly? Large Space Habitats Instead Open Solar System To Humans

SpaceX have a striking video showing Mars spinning faster and faster, transforming from the current red Mars to a planet with a small ocean and with the deserts tinged with green in seven revolutions. Of course that is poetic exaggeration - it wouldn't terraform in a week. So how long would it take? Science fiction enthusiasts who have read Kim Stanley Robinson's "Mars Trilogy" may remember that in his book, it is terraformed in a couple of centuries. But that's science fiction, not a terraforming blue print.

Is This Why We Haven't Found Life On Mars Yet? Value Of Actually Looking

Is This Why We Haven't Found Life On Mars Yet? Value Of Actually Looking

We have been sending missions to Mars since the Mariner 4 flyby in 1964, and our first successful landing was Viking 1 in 1976, So, why can't astrobiologists answer the question definitively, when you ask them if there is life on Mars?  Well, perhaps it's because we haven’t looked. You might think,

Elon Musk's Cherry Red Tesla Roadster Could Be Interstellar Traveller A Billion Years From Now - If It Doesn't Hit Sun Or Planet

So Elon Musk's Tesla roadster is now in an orbit that takes it right out to the asteroid belt not far from Ceres. And what a thrilling launch it was with the two boosters landing so perfectly choreographed. It was nearly flawless. Only one minor hiccup, that the core booster missed the barge and crashed into the water, probably at around 300 mph, scattering the barge with shrapnel. They will surely fix that too with future launches.If any of you haven't seen it yet, here is the launch video archived by SpaceX.

The Doomsday Clock Is More Accurately A ‘Symbolic Clock For Averting Disasters’

The Doomsday Clock Is More Accurately A ‘Symbolic Clock For Averting Disasters’

We get a regular announcment by the bulletin of Atomic Scientists at this time of year every year. It doesn't mean anything is going to happen soon. Indeed their focus is on the long term, not the short term. For instance the Cuban missile crisis didn’t lead to a shift in the clock. It is nothing to do with any short term politics about Norht Korea or Iran. Nowadays they also include global warming as an issue and the worst effects of that will be towards the end of the century. So when it says “2 minutes” - those minutes are not an actual time period. It’s a metaphor, indeed hyperbole (exaggerated analogy for emotional effect). The Doomsday Clock is neither about Doomsday and nor is it a clock.
