What Opportunity, NASA's Mars rover, achieved for humankind
The European car is parked 92% of the time. When the car is used, only 1.5 of its 5 seats
are occupied. Less than 20% of the total petroleum energy is translated into kinetic energy, and only 1/13 of that energy is used to transport people. As much as 50% of inner-city land is devoted to mobility (roads and parking spaces). But, even at rush hour, cars cover only 10 percent of the average European road.
8 hours of flight traffic over Europe animated. Looks quite busy, doesn't it? Animated with #QGIS. Data from @flightradar24
Galileo satellites prove Einstein's Relativity Theory:
Europe’s Galileo satellite navigation system – already serving users globally – has now provided a historic service to the physics community worldwide, enabling the most accurate measurement ever made of how shifts in gravity alter the passing of time, a key element of Einstein’s Theory of General Relativity.
Entra en vigor #MadridCentral zona de bajas emisiones en la que estará restringido el tráfico de vehículos, excepto residentes, transporte público, los vehículos de determinados colectivos necesarios para la vida del distrito y los menos contaminantes
The sensors on board take one image for each band so
there is a slight temporal offset between the images taken. This offset is corrected for ground level so objects on the ground appear as if taken by a single camera at the same time. The parralax error introduced by the altitude of the plane leads to this visible offset

When we published imagery of the #Veneto 🇮🇹 region after the torrential rains of end October, we did not notice this airplane flying over Venice, and the nice rainbow coloured-contrail

As other archipelagoes of Macaronesia, Canary islands are thought to be the product of hotspots.
The Teide-Pico Viejo stratovolcano, at 3,718 m, is the highest peak on Spanish soil. Rising 7,500 m above the ocean floor, it is regarded as the world’s third-tallest volcanic structure.
Seems like is a collaboration between Lockheed Martin & AWS to integrate the new AWS Ground Station service with Lockheed Martin’s new Verge antenna network.
Meanwhile on Mars #14 – Welcome, Insight
WOW!! AWS now have Ground Stations as a Service to command and control satellites, downlink & process satellite data on-demand.
We are proud to have played our small part in InSight's #MarsLanding. Congratulations NASA!
