The Long Swath

On April 12, 2013, the Landsat Data Continuity Mission (LDCM) reached its final orbit, 705 kilometers (438 miles) above Earth. One week later, the satellite’s natural-color imager scanned a swath of land 185-kilometers wide and 9,000 kilometers long (120 by 6,000 miles)—an unusual, unbroken distance considering 70 percent of Earth is covered with water. That flight path—depicted on the globe below—afforded us the chance to assemble 56 still images into a seamless, flyover view of what LDCM saw on April 19, 2013. Stretching from northern Russia to South Africa, the full mosaic from the Operational Land Imager can be viewed in this video. Read and view more at http://earthobservatory.nasa.gov/Feat…

You’ll probably want to stick it on full screen. Make sure you’ve got some suitable music to hand.

This excellent YouTube comment by “nhstorrs” puts it in perspective: 

No way. This is amazing! Landsat flew right over the spine of the birthplace of the human species, and at the same time the birthplace of agriculture. This is where we came from, and the environment which might be said to have had the biggest impact on what made us. . . us. There could almost be no other landscape so interesting to see in one large glimpse as this one.

Weather maps are scary

Here is tropical cyclone Yasi, breaking into Australia, Katrina style, just weeks after floods ripped the river banks open and swamped the streets:

And a map of its progress:

Meanwhile this little beauty is the blizzard that’s walloping Chicago into the ground and stopping anyone from going anywhere or doing anything:

Don’t forget, the USA and Australia are BIG places. These are BIG clouds.
