Taiji Program in Space

The Taiji Program in Space, or Taiji, is a proposed Chinese satellite-based gravitational-wave observatory.[1][2] It is scheduled for launch in 2033[3] to study ripples in spacetime caused by gravitational waves. The program consists of a triangle of three spacecraft orbiting the sun linked by laser interferometers.

There are two alternative plans for Taiji. One is to take a 20 percent share of the European Space Agency's LISA project; the other is to launch China's own satellites by 2033 to authenticate the ASE project.[4] Like LISA, the Taiji spacecraft would be 3 million kilometers apart, making them sensitive to as similar range of frequencies,[5][6] although Taiji would perform better in some of that range.[7]
