ESA/NASA : LISA gravitational wave observatory : 2037

So exciting. Been waiting years for Lisa, and many to go. But its gonna be crazy when its deployed!

Many many years.  I've worked on a prototype of a subsystem more than 20 years ago.  What's another 20.  Maybe I'll see it fly?

Is any of the navigation/control work for LISA feeding into the Proba-3 mission?

Scott Manley gives his take on this technology and mission:

Why We Must Build a Massive Gravitational Wave Telescope In Space - The LISA Mission

Nov 22, 2024
The Laser Interferometer Space Antenna - LISA is a set of 3 spacecraft which will work together to make a massive gravitational wave telescope in deep space, with arms millions of kilometers long it will be able to detect events at much lower frequencies, meaning we can detect black hole mergers months ahead of the event, and entirely new phenomena involving supermassive black holes.

The LISA spacecraft at there core use free flying gold cubes as reference masses for the telescope arms, and managing these so that they remain in free fall is a core capability that was so critical to the success of the mission that they launched the LISA Pathfinder mission to test the technologies needed for the final mission to prove that the system would maintain the levels of control required for good science.

Teledyne Space Imaging has been awarded the role of prime contractor for the Constellation Acquisition Sensor instrument, contributing to the European Space Agency’s Laser Interferometer Space Antenna (LISA) mission.

The UK imaging sensor manufacturer is using its capabilities in detector technology and prowess in proximity electronics to deliver six CIS220 detectors and the control electronics for the international space observation project. Teledyne will do this in partnership with Thales Alenia Space in Switzerland, who will be responsible for the optical head.

Exail, the France-headquartered photonics company, says it has won a contract with the French Space Agency (CNES) to develop and deliver an “ultra-stable” laser system for the planned Laser Interferometer Space Antenna (LISA) mission.
