Video: Eclipse-making double-satellite Proba-3

Proba-3 is ESA's—and the world's—first precision formation flying mission. A pair of satellites will fly together relative to the sun so that one casts a precisely-controlled shadow onto the other, to create a prolonged solar eclipse in orbit.
In the process, the mission will open up the sun's faint surrounding coronal atmosphere for sustained study. Normally, this corona is rendered invisible by the brilliant face of the sun, like a firefly next to a bonfire.
Due for launch together this autumn, the two Proba-3 satellites will fly 144-m apart for up to six hours at a time to create these eclipses. Beside its scientific interest, this experiment will be a perfect method to demonstrate the precise positioning of the two platforms. It will be enabled using a novel combination of guidance technologies. In this video, the Proba-3 team details the mission concept.

A mission to find 10 million near-Earth asteroids every year

So far, scientists have found around 34,000 near-Earth asteroids (NEAs) that could serve as humanity's stepping stone to the stars. These balls of rock and ice hold valuable resources as we expand throughout the solar system, making them valuable real estate in any future space economy. But the 34,000 we know of only make up a small percentage of the total number of asteroids in our vicinity—some estimates theorize that up to 1 billion asteroids larger than a modern car exist near Earth.
A project from the Trans Astronautics Corp (TransAstra), an asteroid-hunting start-up based in California, hopes to find the missing billion: the Sutter Ultra project. Before we get into what Sutter Ultra is, it's best to understand why we have such a hard time finding the hundreds of millions of small asteroids in our vicinity.
To put it bluntly, the problem is two-fold—brightness and speed.
