Editor’s Corner

Steve Platnick, EOS Senior Project Scientist – Acting 

I’m pleased to report another milestone for the Landsat program. We reported in our last issue that March marked the 25th anniversary of the launch of Landsat 5, and now, on April 15, Landsat 7 celebrated the 10th anniversary of its launch. The Landsat 7 mission operated flawlessly until May 2003 when a hardware component failure left wedge-shaped spaces of missing data on either side of the image. Despite the resulting loss of 22% of the image data from in each scene, Landsat 7 data continues to be highly useful. The excellent data quality, consistent global archiving scheme, and now free data of Landsat 7 are hallmarks of its impressive tenure. Both Landsat 5 and 7 have far exceeded their design life and continue to provide vital images of Earth’s land surface. Congratulations to the Landsat Team on yet another remarkable milestone for the program! You can read a summary of the most recent Landsat Science Team meeting on page 27 of this issue. The summary contains updates on the current Landsat missions (Landsat 5 and 7) and plans for the Landsat Data Continuity Mission (LDCM), now targeted for launch at the end of 2012.
