Good news from the Stars

"The first rock a NASA rover looked at when it arrived at a crater on Mars was unlike any looked at on the planet before, scientists said."

But the other news is how long this rover has last: landed in 2004, it was designed to last much much less than the 7 years it has survived.

Well done Wall-E !!!! ;-)

Once futuristic visions, solar sails now take off...

 

Or so we hope.

 

Anyway, it's a good article summarizing the story on solar sail: how they work and the progress we've made so far.

Rising greenhouse emissions could tip off aliens that we are a rapidly expanding threat, warns a report... I hesitated before publishing that article from the Guardian as the subject is really too much speculative to me. But I ended up thinking this was interesting to share anyway. With warnings. This report looks to me like a drunken-geek discussion on the outcome of a potential alien first encounter but hey, it's probably cool to some to realize that some scientists end up with the same conclusions while sober.

Not enough budget to fly to Mars? Let's help writers tell the story as if it happened really!

Asteroid 2011 MD is the size of a tour bus. The asteroid will fly past Earth today (June 27) so closely it will be beneath some of the planet's satellites.

But too small to be causing damage anyway and no chance it hits the earth.

How do stars move in the sky? This video gives an interesting perspective by takin them as a fixed point and showing everything else rotating around. Watch it!
