New NASA satellite continues its half-century journey of calculating Earth and climate change


Although the data from the Landsat missions proved invaluable, they were somewhat disappointing, as satellites collected an impartial record of tropical deforestation in the Amazon, verifying the claims of environmental protection organizations.

They also rank the increasing water scarcity in the western United States and record ice losses across the vast majority of glaciers on Earth, arstechnica reports.

Landsat is a group of satellites launched successively by NASA since 1972 until now, and NASA gave them serial designations.

Scientists in the journal Remote Sensing of Environment concluded in 2020 that “Landsat has provided an important reference for evaluating long-term changes in the Earth’s environment due to natural and anthropogenic influences.”

Basically, you can’t manage what you can’t measure, so if we’re smarter about how we change the planet, maybe humans will get smarter about how to change the planet in the future.

Now NASA is seeking to cement the legacy of the Landsat program with the launch of the Landsat 9 mission. In many ways, the satellite is a copy of Landsat 8, which was launched in 2013, yet the new satellite includes an infrared thermal sensor as well as backup systems to allow the device to operate for a while. The tallest, these satellites weigh about 3 metric tons; The mass of the original Landsat is 900 kg.

The Atlas V rocket, built by the United Launch Alliance, will propel the Landsat satellite into a near-pole orbit. This will be the 300th rocket of the Vandenberg Atlas family, dating back to August 1962, and this will be the 88th launch of the Atlas 5 rocket. , which previously launched the Landsat 8 mission.
