[ESA] LISA Pathfinder results

SciTech/Science Written on 2016.06.09 12:07

Launched in December 2015, LISA Pathfinder travelled to its operational orbit, 1.5 million km from earth towards the Sun, where it started its scientific mission on 1 March. At the core of the spacecraft, two identical gold-platinum cubes, are being held in the most precise free-fall ever produced in space.

Placing the test masses in a motion subject only to gravity is the challenging condition needed to build and operate a future space mission to observe gravitational waves. Predicted by Albert Einstein a century ago, gravitational waves are fluctuations in the fabric of space-time, which were recently detected directly for the first time by the Laser Interferometer Gravitational-Wave Observatory. ▶LISA Pathfinder exceeds expectations (ESA)
