Given our dependence on the communication systems of our planet, both satellite- and ground-based, this is not simply a theoretical worry.
The moon hung over this space, and it was as if the planet and its satellite were acting as mirror images of each other.
Essentials, the Earth in 3D, includes detailed maps and satellite views of the entire planet .
As well as using high-precision monitoring to check for fluctuations in the star's brightness, the satellite will also determine the planet's radius.

The Esa satellite's radiometer works by measuring the natural emission of microwaves coming up off the planet's surface.
By unleashing a massive pulse of electromagnetic radiation sweeping over the planet, a severe solar storm could potentially knock out the electric power grid, silence radio and satellite communications and disrupt GPS navigation systems.
Pictures of the icy satellite Enceladus suggest its surface splits and spreads apart - just like the ocean floor on our planet splits to create new crust.
