Two years ago, spacecraft entered the atmosphere of Saturn, becoming part of the planet it had explored for 13 years.

New research emerging from NASA's Cassini spacecraft represents a huge leap forward in our understanding of the Saturn system:

* length of a day on Saturn. It's 10 hours, 33 minutes and 38 seconds.

* the rings may have formed much later than the planet itself

* probed Saturn's magnetized environment

After 20 years in space — 13 of those years exploring Saturn — Cassini exhausted its fuel supply. And so, to protect moons of Saturn that could have conditions suitable for life, Cassini was sent on a daring final mission that would seal its fate.

After a series of nearly two dozen nail-biting dives between the planet and its icy rings, Cassini plunged into Saturn’s atmosphere on Sept. 15, 2017, returning science data to the very end.

If we are going to refer to bank payments as ‘cashless’, we should then refer to cash payments as ‘bankless’. Because that’s what cash is... right now it is the only thing standing between us and a completely privatised money system.

Using artificial intelligence to automate sea-ice charting

The ASIP project merges imagery with other satellite sensor data and uses a convolutional neural network system that is trained with vast datasets of ice charts, to generate ice maps automatically.

ASIP will be made freely available through the Danish Meteorological Institute (DMI) Ice Service, for both public and commercial users.

Do transportation network companies decrease or increase congestion?

TNCs are the biggest contributor to growing traffic congestion in San Francisco. Between 2010 and 2016, weekday vehicle hours of delay increased by 62% compared to 22% in a counterfactual 2016 scenario without TNCs

Yes, @mozilla makes mistakes (same as the rest of us humans). And yes, their last one was ugly. But, still, they're the only ones in the browser business trying to do the right thing. So I'll keep using Firefox, Focus, Send, and the rest of cool software they produce.
