VerySpatial informs us that despite several recent troubles, Landsat-5 is resuming operations. Last October troubles have been circumvented but the need for a Landsat Data Continuity Mission is obviously still relevant. From the USGS announcement: "The USGS is pleased to announce that Landsat 5 resumed imaging on January 10, 2008. Landsat 5 imaging was suspended on October 6, 2007 due to a battery cell failure with one of its two working batteries. [...] In November 2005, Landsat 5 transitioned to operations using a fixed solar array due to a failed motor which reduces the efficiency of battery charging. This, combined with the reduced power available from the batteries, increases the complexity of maintaining a safe power balance while collecting imagery.
Over the next few weeks, the team will continue to increase collection of imagery while closely monitoring power. Data collected will be available soon following analysis and calibration of the data."

The EOPortal informs us that Landsat 5 is experiencing problems. Not much info on this yet: "On October 6, 2007, Landsat 5 experienced an issue with its onboard batteries, leading to concerns about power balance. Imaging will be suspended while the flight operations team analyzes the problem. The Landsat team expects the investigation will last from 2 to 3 weeks. Further announcements will be made as needed." This is not the first time Landsat-5 technical problems occur.
Landsat Data Continuity Mission Update
[+]
Last week ago we told you about Landsat-5 problems, Very Spatial links to a NASA update on the Landsat Data Continuity Mission. This topic was discussed a few times before (see previous stories below). The article's introduction: "In a world newly awash with geospatial information, only Landsat offers a rich archive of global mid-resolution, highly calibrated, multispectral data of Earth’s landmasses. To extend this legacy, plans are in the works for a July 2011 launch of the Landsat Data Continuity Mission (LDCM), which will collect and archive data consistent with its predecessor Landsat satellites. This July, NASA selected Ball Aerospace and Technology Corporation to build LDCM’s Operational Land Imager (OLI) instrument, bringing the long-awaited Landsat follow-on mission closer to actualization."
