Enjoy for the first time in History a smooth, interactive and infinite video of our planet in rotation, on its fully lit side.

Just sit and watch for an amazing Earthgazing session, feel the Overview Effect, or just explore touching the Earth like you would move across time and space.

This viewing experience is based on rea pictures of the Earth, as a public images courtesy by NASA. The images are delivered by the EPIC camera on board the DSCOVR satellite, located in the "L1" Lagrange point, 1 million miles from the Earth, right on the Sun axis on a permanent basis due to the balancing of gravitational forces. This vantage point, unique in the Universe, gives us a permanent view on the fully-lit, day-side of the Earth.

It is like you were seeing the Earth from the Sun...

Images are interpolated using an advanced algorithm, while they are streamed in from NASA's servers, turning this app into a literal Earth player.

Note that, depending on NASA's discretion, some images are missing and we replace by a dummy synthetic earth. Also, latest available images may be a few days late.

More touch interface tips
- Drag left and right to "move time" and therefore rotate the Earth
- Drag up/down to increase/decrease time speed factor
- Fling up or down to jump a full 24h day.
- Pinch to zoom on a region
- Double-tap to zoom and follow a geographic location and better see clouds passing by
- Tap on the date to open the calendar and choose any date since the first published image on July 15th, 2015

So many things to observe:

* See the real clouds, slowly moving as the Earth rotates.

* See the seasons through the Earth tilt angle by choosing a date in the past solstices (until July 2015 when DSCOVR EPIC started sending its first pictures back to Earth).

* See the living Earth from the view point of our only light source.

* See our only home as you have never seen it before.
