The feat, which involved firing powerful laser pulses at thunderclouds over several months last year, paves the way for laser-based lightning protection systems at airports, launchpads and tall buildings.
A new study shows that massive volcanic eruptions over an extended period of time may be responsible for changing the planet into what it is today. If there was simple life on ancient Venus, volcanism was its doom. The study also shows how powerful volcanic activity has played a role in shaping Earth’s habitability and how Earth only narrowly avoided the same fate as Venus.
Venus is hot enough to melt lead, which is why no spaceship has ever survived to land on the surface.
And, no, there is nothing alive floating around in its toxic atmosphere.
But this is a neat article. Three future missions are planned for Venus (two by NASA – VERITAS and DAVINCI – and one by ESA – EnVision, which sounds more like a song and dance competition than a scientific probe).
In short, the algae will use sunlight to transform CO2 into sugars that are then enhanced by bio-engineered E.coli into 2,3-butanediol. Interestingly, 2,3-BDO is not entirely conceptual as it currently exists and is mainly used to produce rubber components. It has just never been thought of as fuel before.
