7 |
An instrument malfunction occurred onboard
Landsat 7 on May 31, 2003. The problem
was caused by failure of the Scan Line
Corrector (SLC), which compensates for
the forward motion of the satellite. Subsequent
efforts to recover the SLC were not successful,
and the problem appears to be permanent.
Landsat 7 data ceased to be acquired by
ESA stations from that date.
Landsat 7 SLC-Off world-wide imagery continues
to be acquired by USGS through the on-board
tape recorder. Eurimage distributes the
Level 1G Standard SLC-off product, containing
the original data gaps, which gradually
diminish in width toward the center of
the scene. Standard Level 1G processing
applies a small (2-pixel) interpolation
along the scanline boundary, and all remaining
duplicated image data are replaced with
null values (zero-fill). |
Landsat 5 |
Landsat 5 data has been regulalrly acquired
at the ESA Matera station since 1 January
2004 (regular acquisitions at ESA stations
had ceased on 30 June 2001). A set of Landsat
5 acquisitions at Matera from 26 June to
30 September 2003 is available from USGS
archives. |
Mission |
The first Landsat satellite was launched
in 1972, since when a further five satellites
have been successfully launched. |
