Based on the provided sentence, here are some potentially suitable completions, as words have been placed into “Response area,” which seems to refer to areas of Earth science data and support. I will provide the sentence with suggested words filled in for clarity:
NASA Response area provides data on Earth's land, ecosystems, water, air, temperature, and climate - and has done so for more than 50 years. Earth information from NASA supports decision-makers, partners, and people in developing the knowledge they need to mitigate, adapt, and respond to our changing planet.
Feel free to adjust the words based on specific terminology you think is desired. Without additional context or choices, this is a generalized response.
