WHAT is the L3ST?

A study for NASA participation in the ESA-led L3 Gravitational Wave Mission (2016-2018)

L3 Study Team (L3ST)

  • L3ST Interim Report - 20 June 2016 [PDF]

Note that as of July 2017, following the selection of LISA as the ESA L3 mission, the L3ST study activities are coming to an end, and NASA is soliciting applications by September 1, 2017 for the new U.S. LISA Study Team.

NASA is partnering with ESA on the third Large-Class mission (L3) in ESA's Cosmic Vision 2015-2025 Programme, planned for launch in 2034. ESA has selected a gravitational wave observatory as the science theme. To this end, NASA has formed an L3 Study Team (L3ST) composed of selected members of the community. A Dear Colleague Letter was issued on December 7, 2015, soliciting nominations and self-nominations for the L3ST, with due date December 21, 2015. Submitted applications were reviewed by members of the NASA HQ Astrophysics Division and of the Physics of the Cosmos (PCOS) Program office, who then made selection recommendations.

The purpose of the L3 Study is to understand how NASA might participate in ESA's L3 Gravitational Wave mission, to inform our engagement through its earliest stages and to prepare for the 2020 decadal survey.
