#Technology image of the week. The Atacama Desert #Chile , the driest place on Earth – despite being right next to the Pacific Ocean – imaged by ESA’s #ProbaV minisatellite.

Finally, the band width that New Horizons has tp transmit to earth. It'll take 500+ days to transmit all its data back to Earth.
 
Pluto in a Minute: Why Is It Taking So Long to Downlink Data from NASA's New Horizons? | July 27, 2015: You know how we keep saying there' more data to come from New Horizons? This is why. And this is Pluto in a Minute...So part of the problem is that the spacecraft has a limited amount of power on board because of its battery. The spacecraft can generate about 200 watts but that's to power all the instruments. But the team has to specify which instruments are running when. When the spacecraft is taking minimal measurements, it actually goes into what's called a spin stabilization. The spacecraft is spinning so it's not actively using its gyros or its reaction controls to orient itself. 

But just because the instruments aren't actively taking data doesn't mean the transmitter gets more power. It just means that, because fewer systems are working, the transmitter is able to be on. 

So when the spacecraft is spinning it can actually achieve higher data rates of between 1,000 and 4,000 bits per second. But there are 50 gigabits of data on the spacecraft! So! Let's break down how long it's going to take to get all that back! 

Give its antenna size and limited by its power source, New Horizons can download seven megabits of data per hour. Each downlink is about an eight hour pass because of the rotation of the Earth, so that's 58 megabits in each pass, which amount to about 173 megabits every day. With 50,000 megabits on board downloading 173 megabits a day, and we don't have exclusive access to the deep space network, that takes about 500 days to get all the data from New Horizons back to Earth.

Excellent. We were looking for a place with good food, not greasy fried stuff, and this was it. I recommend the fish taco, with blackened or spicy tuna, the tuna nachos and the meat. Great for lunch and dinner. Also, make a reservation as it gets full on sometimes.
