On Thursday, January 26, 2023, an anomaly caused the Landsat 8 spacecraft to enter a safehold mode. The spacecraft recovered from the safehold on January 28, 2023. Since that time, the Landsat 8 Flight Operations Team has confirmed that all satellite subsystems are nominal, and imaging resumed.

Landsat 8 image of the Sierra Madre Oriental mountain range in Coahuila, Mexico acquired on January 29, 2023. The image is show using the short-wave infrared, near infrared, and green bands (6|5|2).

Landsat 8 Real-Time (RT) products acquired from January 29, 2023 (DOY 29) to present are now available for download but remain provisional.   

Note:  Data acquired after the spacecraft recovered (January 27-28) are being held from processing while the USGS/NASA Calibration/Validation Team inspects the data and determines if this data can meet nominal Landsat geometric and/or radiometric quality.  

In approximately one week, all Landsat 8 acquisitions from the point of resuming nominal operations after the spacecraft entered safehold will be processed to Tiered data with all necessary and typical calibration updates.   

Users who download provisional Landsat 8 RT data during this time should monitor subsequent updates from the USGS Landsat program. Another status will be provided once the Landsat 8 provisional data reprocessing timeline has been determined.
