February 24 marks the fifth anniversary of the first data imaged from the Terra MODIS instrument. The sensor was launched aboard Terra on December 18, 1999, and starting collecting data on February 24, 2000. Since "First Light", MODIS has processed V001 (beta), V003 (provisional), and V004 (validated) data, and is planning to release V005 in 2006 to continue supporting improved understanding of the Earth system.
