For over two decades Terra has collected valuable information about Earth’s methods. In February 2020 Terra stopped carrying out platform maneuvers that would Command its equator crossing time in order to retain fuel for collision avoidance maneuvers.

The Terra info from each of your five instruments can be accessed in the respective information facilities that host information products and solutions. These information facilities are listed on Just about every instrument information web site.

  The Terra Undertaking entirely expects the Terra platform and all five devices to work previous 2026 making it possible for them to keep up their status as leaders in Earth science data production.  Terra’s lengthy-time period facts report will proceed to contribute to the Earth Science Division’s critical science queries:

The mix of Worldview Snapshots’ power to rapidly make visuals showing any location on this planet and Worldview’s power to enable in-depth interactive exploration of every day international imagery offers consumers with an unmatched, built-in adaptability to check out the planet using NASA Earth observing details.

When these selections for data reduction come at costs, the teams are considering rebooting the reliable-condition recorder, which was performed once in 2001. “There is absolutely no identifiable possibility to doing the reset,” says Kurt Thome, Terra Project Scientist.

“We need to manually mail the update that says, don’t document to that PWA any longer, but until eventually we do that it retains seeking to conserve information to the poor PWAs,” states Jason Hendrickson, Terra Flight Units Supervisor.  Terra’s flight operations Staff quickly worked to initiate instructions to mark the printed wire assemblies as negative so which they were being not utilised.

Having said that, in 2001, soon after the initial printed wire assembly stopped Operating, rebooting the good-condition recorder corrected The problem, restoring purpose. Now with only forty three of 59 printed wire assemblies operating, information storage capability has diminished to some crucial place for MODIS and MISR.

MODIS normally operates with fifty% of your orbit recording of daytime bands (all 36 bands), whereas another fifty% on the orbit information only seventeen thermal bands (night time mode).  The Flight Functions Team can reprogram The proportion break up, extending the night mode facts assortment and decreasing the daytime details selection. This lowers the full amount of info which is collected amongst facts dumps. However, daytime bands are essential for numerous MODIS information items which includes: ocean colour and ocean optical property products, many atmospheric products and solutions, and a lot of land products and solutions.

Details sets are usually offered as Hierarchical Info Structure (HDF) information and there are a number of HDF processing program offered that permit buyers to Screen and look through photos and details file data. Lots of of these application programs are available in the public domain and also commercially.

In a Operating group meeting held in 2019, this scenario was discussed. All instrument teams made options about how to proceed if anymore printed wire assemblies stopped Doing the job. The choices talked about provided: downlinking knowledge far more usually, minimizing the amount of science observations by MISR and MODIS, or rebooting the strong-point out recorder in hopes the printed wire assemblies start to operate once more. Weighing the dangers and great things about these courses of motion isn't taken evenly.

During the time it took to initiate these instructions, both MISR and MODIS misplaced info. Even so, repercussions from these non-operating printed wire assemblies have extended lasting impacts ­– lowered storage capacity of MODIS and MISR data on Terra’s good-condition recorder.

End users can even configure the appliance to provide each day photos of a selected spot of desire, and images could be previewed and altered prior to They can be downloaded. Based on the size from the geographic place picked, Worldview Snapshots even provides a advised best impression resolution from the fall-down menu.

The 9 obtainable foundation levels incorporate MODIS and VIIRS Corrected Reflectance together with quite a few band combinations for highlighting capabilities like snow, ice, and flooding.

Terra will even continue on collecting info just after an orbit decreasing maneuver planned for Slide 2022. The maneuver upholds agreements to ensure Terra is a safe distance from the opposite missions from the 705-km Earth Observing Satellite Constellation when gasoline to take care of Terra’s orbit has long been depleted.

The effective restart of the stable-state recorder in 2001 introduced the very first inoperative printed wire assembly again on the internet. If a restart works, then MISR and/or MODIS could continue on to gather knowledge as was done previous to the recent malfunctions, perhaps even returning Terra’s data storage capability to the amount it had at launch.
