For over twenty years Terra has gathered valuable info about Earth’s techniques. In February 2020 Terra stopped executing System maneuvers that will Management its equator crossing time in an effort to maintain fuel for collision avoidance maneuvers.

The Terra info from Every single of your 5 instruments is usually accessed from the respective facts centers that host data products. These info facilities are listed on Each individual instrument information web site.

“The science community views the modifications in crossing time and orbit altitude as continuation of ordinary knowledge collection for people items not afflicted with the orbital changes together with an opportunity to perform novel science with the ones that are affected,” As outlined by Kurtis Thome, Terra Venture Scientist.

Previous to these printed wire assemblies malfunctioning, fifteen other printed wire assembly stoppages experienced occurred, each time lowering Terra’s stable-point out recorder information storage capability.

Whilst these choices for facts reduction occur at costs, the groups are considering rebooting the reliable-condition recorder, which was performed once in 2001. “There isn't a identifiable hazard to performing the reset,” states Kurt Thome, Terra Undertaking Scientist.

“We really need to manually deliver the update that says, don’t record to that PWA any longer, but till we do this it retains looking to help you save info to the undesirable PWAs,” claims Jason Hendrickson, Terra Flight Systems Manager.  Terra’s flight operations Crew immediately labored to initiate commands to mark the printed wire assemblies as negative so that they have been not applied.

Around the size of a small university bus, the Terra satellite carries five instruments that just take coincident measurements of the Earth process:

MODIS generally operates with 50% in the orbit recording of daytime bands (all 36 bands), whereas another 50% with the orbit data only 17 thermal bands (night time method).  The Flight Operations Group can reprogram The proportion split, extending the night method info selection and reducing the daytime details assortment. This cuts down the entire level of information that is gathered between facts dumps. Having said that, daytime bands are important for numerous MODIS data items like: ocean coloration and ocean optical assets products, several atmospheric merchandise, and plenty of land solutions.

Details sets are generally readily available as Hierarchical Facts Format (HDF) files and there are a number of HDF processing program readily available that let customers to display and search images and facts file details. Many of these program plans can be found in the general public domain and also commercially.

  The Terra Job fully expects the Terra System and all 5 devices to function past 2026 letting them to keep up their status as leaders in Earth science info manufacturing.  Terra’s extended-phrase information record will continue to add on the Earth Science Division’s essential science queries:

Terra is in a round Sunshine-synchronous polar orbit that can take it from north to south (about the daylight side of the Earth) every ninety nine minutes.

Terra, the flagship Earth Observing Satellite, continues to generally be a pacesetter in Earth science knowledge, contributing to scientific analysis and applications globally, now with data ability ranges restored by A prosperous sound point out recorder reboot.

Current lifestyle expectancy: Terra has far exceeded its style lifestyle and it has a robust potential for working efficiently in to the early 2020s. Terra commenced drifting in February of 2020. Examine more about Terra’s drifting or see key dates below.

Experts have the ability to doc interactions amongst Earth’s systems and examine their connections. Also, Terra data has a lot of purposes that assist men and women day to day.

The successful restart with the sound-condition recorder in 2001 introduced the primary inoperative printed wire assembly back on the internet. If a restart performs, then MISR and/or MODIS could carry on to collect information as was performed previous to the the latest malfunctions, perhaps even returning Terra’s knowledge storage ability to the amount it had at launch.
