First for DESI

Caption

The first "petal" machined for the Dark Energy Spectroscopic Instrument (DESI) is shown in these photos. Ten of these petals, which together will hold 5,000 robots (like the one in the lower right photo) -- each pointing a thin fiber-optic cable at separate sky objects -- will be installed in DESI.
