2015-070A
ESA/Airbus ST-7/SMART-2, a single spacecraft with separate NASA (ST7) and ESA (SMART-2) payloads as a LISA/DARWIN technology demonstrator. One satellite which will carry the LTP (Lisa Technology Package) and the DRS (NASA Disturbance Reduction System) in a 1.0m high 2.3m dia octagonal box. A liquid propulsion module will take it from LEO to L1. Launch by Vega.
