The LSST secondary mirror (M2) substrate has been safely relocated from Harvard University in Cambridge, MA to the Exelis facility in Rochester, NY. The mirror’s trek, which involved the use of a 50-ton internal bridge crane to load the mirror transport box onto a wide-load flatbed truck and a 70-ton external crane to offload it at destination, covered 604 miles in a little over a day. The truck and pilot vehicle departed Harvard at 1 pm on October 20 and arrived in Rochester at 3 pm on October 21. Subsequently, Exelis personnel have disassembled the transport box and thoroughly inspected the substrate.
