The process has been widely adopted by space exploration organizations across the globe. They form the basis of many of the best-known projects, and the completion of their phases are events to be celebrated by both the people working on them and the public at large. The Feasibility Phase has passed for the attempt to build a 2.5 million kilometer long interferometer in space by the European Space Agency.
The Laser Interferometer Space Antenna (LISA) is the culmination of forty years of research into how best to capture the waves from black holes.
The team at LISA will need a lot of time to work on furthering the technology, as they already have a head start on some of it.
The Feasibility Phase is where concept studies and models take place.
TheRefinement Phase is where the technologies and systems for the mission will be developed, as well as the international partnerships and launch agreements.
When it does get up there, it will join up with another mission to observe black holes in X-rays and ripples in the waves.
There are more gates to go before the data can be used in the discoveries.

The LISA mission is moving to the final design phase.
