After a successful mission proving the technology for a full scale orbiting gravitational wave detector, LISA Pathfinder was shut off yesterday.
After 16 months of science measurements an international team deactivated the LISA Pathfinder satellite on the evening of the 18th of July 2017. The gravitational-wave laboratory in space powered down after receiving the last commands in the evening and circles the Sun on a safe parking orbit. LISA Pathfinder has tested key technologies for LISA, the future gravitational-wave observatory in space, and has demonstrated their operative readiness. LISA is scheduled to launch into space in 2034 as an ESA mission and will “listen” to the entire Universe by measuring low-frequency gravitational waves.
The idea is laudable, but for Europe to need another seventeen years to build and launch the full scale telescope is absurd. They now know what needs to be done. It should be relatively easy and quick to get it into orbit. And even if it isn’t easy, seventeen more years? Give me a break.
