What is so special about @LISA, the planned gravitational-wave observatory in space?

This “Einstein Online” article provides more information about the European Space Agency (ESA) mission, which is to observe Einstein's space-time ripples with a gigantic laser satellite triangle in the 2030s:

£10 million investment in new space facilities for LISA in Scotland:
New lab spaces will be constructed at the UK Astronomy Technology Centre (UK ATC) to assemble the optical benches for the Laser Interferometer Space Antenna @LISA mission.
The new lab and clean rooms will be hosted at the Science and Technology Facility Council’s UK ATC site in Edinburgh. (This £10 million ESA contract will double UK ATC’s construction capabilities, and build on existing support from the UKSA and its membership of ESA.
The optical benches send and receive the laser beams over a 2.5 million kilometre distance between the 3 LISA spacecraft, enabling measurement of distance changes between them with an accuracy of a few trillionths of a metre (picometers). Work on the optical benches has already begun at UK ATC. The assembly process utilises Robotically Assisted Bonding (RAB), developed by UK ATC and the University of Glasgow and funded by the Uk Space Agency UKSA.
