1992-070B
Lageos 2 was built by Alenia Spazio using the original Lageos drawings. It is used for geodetic research together with Lageos 1. The spacecraft was sponsored by the ASI (Agenzia Spaziale Italiana), in collaboration with NASA/GSFC. The project was begun in 1982 by the CNR/PSN (Consiglio Nazionale delle Ricerche/Piano Spaziale Nazionale), the precursor of ASI.
Lageos 2 had a mass of 405 kg and a diameter of 0.6m. It carried 422 silica glass retroreflectors and 4 germanium retroreflectors. Mounted above the satellite at launch was the LAS (Lageos Apogee Stage), a 388 kg Mage 1SC solid motor, and a 100 kg LAS Adapter. This combination was attached to the IRIS (Italian Research Interim Stage) spinning solid stage, with a launch mass of 1534 kg, 264 kg dry. The IRIS/Lageos 2/LAS payload was installed in Aeritalia-built ASE (mass 1003 kg) in Space Shuttle Columbia's payload bay on mission STS-52. The ASE was similar in appearance to the PAM-D ASE.
