Satellites Observing Earth's Changes Every Day

When examining ‘Landsat 1’, its distinctive features can be found in the mission trajectory. This spacecraft is the first satellite from the Landsat program, which has been conducting long-term civilian Earth observation. It was launched by NASA and USGS on July 23, 1972, and aimed at Earth as a multispectral Earth observation satellite. By looking at these four pieces of information together, we can distinguish ‘Landsat 1’s historical position and actual mission range that isn’t revealed by the name alone.

What’s most interesting about ‘Landsat 1’ is that it marks the starting point of comparing land changes by recording the same surfaces across multiple wavelengths. When reading mission data from ‘Landsat 1’, it’s worth following not just the successful scenes but also the procedures that reduced risks. The mission status of ‘Landsat 1’ is ‘Mission Completed’, and for decommissioned spacecraft, we should read their data and follow-up technologies left behind, while for operational spacecraft, we should focus on tasks expanded from the original plan. This way, it becomes clear that ‘Landsat 1’ was not just a simple record holder but a tool that solved specific problems.

Following the flow of the list, it’s worth examining ‘Terra’. Comparing ‘Landsat 1’s multispectral Earth observation satellite with ‘Terra’s multisensor Earth observation satellite, we can confirm that the method of reading Earth changes through repeated observations was accumulated not from a single invention but from the trial and error of multiple missions. The official page for ‘Landsat 1’ provides more detailed information about its launch, mission progress, and payload, so for ongoing missions where dates and statuses change, it’s safer to check the latest notices together.

When examining ‘Terra’, its value lies in the criteria it left for the next missions rather than just the stunning records. This spacecraft is a satellite that long-term observes the interactions between land, atmosphere, and oceans using five sensors. Launched by NASA on December 18, 1999, it aimed at Earth as a multisensor Earth observation satellite. By looking at these four pieces of information together, we can distinguish ‘Terra’s historical position and actual mission range that isn’t revealed by the name alone.

What’s most interesting about ‘Terra’ is its configuration, which collects different Earth system data from a single platform. When looking at ‘Terra’, understanding the sequence in which equipment was used after reaching the target clarifies the design.
