Mount Etna is Europe’s largest and most active volcano. Located on the eastern coast of Sicily, Italy, in the province of Catania, the active stratovolcano is known for its frequent and persistent eruptions. Activity can range from explosive eruptions to lava flows and ash emissions.
What are the acquisition schedules for the Landsat satellites?
The Landsat 8 and Landsat 9 satellites orbit the Earth at an altitude of 705 kilometers (438 miles) in a 185-kilometer (115-mile) swath, moving from north to south over the sunlit side of the Earth in a sun synchronous orbit, following the Worldwide Reference System (WRS-2). Each satellite makes a complete orbit every 99 minutes, completes about 14 full orbits each day, and crosses every point on Earth once every 16 days.
The satellite orbits are offset to allow 8-day repeat coverage of any Landsat scene area on the globe. Between the two satellites, approximately 1,500 scenes are added to the USGS archive each day.
Traveling on the descending (daytime) node from north to south, the satellites cross the equator on each pass at a time that provides the maximum illumination with minimum water vapor (haze and cloud build-up). Landsat 8 and Landsat 9 cross the equator at 10:00 a.m. +/- 15 minutes (mean local time) in their respective orbits
The Landsat 8 and Landsat 9 satellites each acquire data in accordance with their respective Long Term Acquisition Plan (LTAP) using parameters such as seasonality, land definition, historical cloud cover, gain settings, and sun angle.

The Landsat 8 and Landsat 9 satellites together acquire approximately 1,500 scenes daily. These scenes are available for download within 6 hours of acquisition. Landsat satellite acquisitions are managed as a system, known as a satellite constellation. Long-Term Acquisition Plans (LTAPs) direct and optimize the daily acquisitions of each active Landsat satellite. Special requests for future...
How can I find the acquisition time for a Landsat scene? How can I find the acquisition time for a Landsat scene?
Landsat descending (daytime) acquisitions run from north to south; they cross the equator between 10:00 am and 10:25 am local time on each pass to provide maximum illumination. The acquisition start and stop times for each scene are listed in the metadata file that is included in the Landsat Level-1 product, and are also displayed on EarthExplorer and GloVis. Landsat data acquisition times are...

Ascending (nighttime) WRS-2 Path/Row numbers are different from descending (daytime) Path/Rows. Cloud cover values for Landsat night scenes will always be zero. If you know the daytime path/row or coordinates and want to know the nighttime path/row, use the WRS-2 Path/Row to Latitude/Longitude Converter. Use EarthExplorer to search using path/row or coordinates: Access EarthExplorer. On the Search...

The tragic fires sweeping across the Greater Los Angeles area in January 2025 have burned more than 40,000 acres, destroyed more than 12,300 structures, and prompted evacuation orders and warnings for as many as 200,000 residents. Exceptionally dry conditions, coupled with strong Santa Ana winds, have fueled the fires.

The U.S. Geological Survey (USGS) has improved Landsat data quality and usability through the creation of Analysis Ready Data (ARD) for the conterminous United States, Alaska, and Hawaii. Landsat ARD greatly reduces the preparatory work currently required to do time-series analysis for understanding landscape change for operational and science users.
