🛰️ MODIS Terra scheduled to exit the 'Morning Constellation' of Earth Science satellites by October 2022.


By the Fall of 2022, Terra’s crossing time will exceed 10:15 am. Then, Terra, will be lowered to a new orbit where it will be able to collect valuable data at an even earlier crossing time. As Terra’s crossing time creeps earlier, small changes will be noticeable in Terra’s data and imagery. Evidence in imagery of the earlier crossing time will be visible as longer shadows, especially in mountain landscapes. Meanwhile as Terra moves closer to Earth, the sensors’ views will become narrower leading to slightly narrower swath widths. The effect will be most noticeable in ASTER imagery, but each of Terra’s sensors will be affected. However, the impact on science is expected to be minimal. In fact, some impacts could prove beneficial to some areas of research – like land morphology, surface temperature, and climate research
