THE ultimate stereoscopic camera
In 2013, ESA will launch Gaia, the most powerfull stereoscopic camera ever build to the L2 Lagrange point (a million-and-a-half kilometres from Earth) where it will stay taking pictures for at least 5 years. Gaia will catalogue a thousand million stars, producing 10,000 times more data than the previous Hipparcos mission.
The on-board gigapixel stereoscopic cameras were not designed with hairdressers in mind. However, they will have the capacity of measuring the diameter of a human hair at 1000 km!
