M1M3 Cart Completion

The transport cart for the Primary/Tertiary Mirror (M1M3) Cell Assembly has been completed at CAID Industries in Tucson, AZ. On the summit of Cerro Pachón, this cart will be used to safely detach M1M3 from the telescope and transport it to the coating plant for periodic maintenance of the mirror. The cart will move along rails that are built into the floor of the observatory building. A vertical platform lift will carry the cart between the telescope and maintenance levels of the building.
