JEFF MASEK / Landsat 9 Project Scientist If you’ve used Google Earth, then you’ve seen images of our home planet that only a satellite can bring you. Many of these images come from the Landsat mission -- a joint venture between NASA and the U.S. Geological Survey (USGS). Since the first Landsat launch in 1972, Landsat satellites have provided us with continuous high-resolution images of Earth that are both stunning to look at, and packed with data that have helped shape our understanding of our planet. In particular, the decades-long data record helps researchers around the world understand how Earth is responding to natural and human-caused changes. Over almost 50 years, the Landsat satellites have watched as cities grow, rivers overflow their banks, sea levels rise, wildfires burn and farmers plant their crops. On Monday Sept. 27, NASA will launch Landsat 9, the next in a storied line of missions observing Earth’s surface. ** Launch window opens at 2:11pm EST / 11:11am PST that day! ** The Landsat 9 observatory will continue to build on this understanding of our home planet with even higher imaging capabilities than previous Landsats. Join NASA and USGS experts for one-on-one interviews just hours before Landsat 9 launches from Vandenberg Air Force Base in California. * Live interviews will be available from 6:00 a.m. to 12:30 p.m. EASTERN TIME on Monday, Sept. 27rd. *Click here to request an interview: https://forms.gle/vREXDyc8aaYzF1tu8* For more information about Landsat visit: https://www.nasa.gov/specials/landsat/ *Please note that we may not be able to accommodate all requests for a specific expert. If we cannot fit your request we will offer alternatives.* Suggested Anchor Intro: If you’ve used Google Earth before you’ve seen images of our planet that only a satellite can bring you. Many of these images come from the Landsat mission, which has been monitoring how Earth is changing for nearly 50 years. NASA and the USGS will be launching Landsat 9 today to continue bringing you those images, which help experts manage wildfires and water resources and help track the impacts of climate change. Here to tell us about the mission is NASA [or USGS] scientist XX. Suggested Questions:Landsat 9 is launching today to continue the mission that started in 1972. What is the Landsat mission?How is Landsat 9 different from the previous Landsat satellites? Landsat is known for its beautiful images, but this data is telling us a lot about how our planet is changing. How does Landsat data directly help people on the ground?Why is it important that NASA and USGS continue the Landsat mission?Where can our viewers go to learn more about Landsat? Questions for Longer Interviews:How does this help people/resource managers?How does this help us grow food?How often do Landsat satellites image a given place on Earth?

Landsat collects images in long narrow strips called “swaths.” Each swath is 185 kilometers (115 miles) wide and is 2,752 kilometers (1,710 miles) from the next adjacent swath taken that day. It takes 16 days for the swaths to overlap enough to image the whole Earth.Previous Landsat sensors swept back and forth across the swath like a whisk broom to collect data. The sensor looked at a calibration source at the end of every row, which means that measurements were consistent from orbit to orbit. But this sensor design requires fast-moving parts, which are more likely to break.—and which did on Landsat 7.In contrast, the instruments on Landsat 8 view across the entire swath at once, building strips of data like a pushbroom. This approach requires no moving parts and gives the sensor detectors greater dwell time. The pushbroom instrument is smaller and lighter than previous whisk broom instruments, but its calibration is much more complex given the large number of detectors.“It was a natural step to evolve to a pushbroom sensor. The technology was proven on other satellites, and we knew we could get better accuracy. The pushbroom has no moving parts. It is a newer and more reliable technology.” explains Terry Arvidson, senior project engineer.For more information on the future of Landsat instruments, read https://landsat.gsfc.nasa.gov/landsat-9/instruments/. The instruments on Landsat 8 have linear detector arrays, also called detectors, which collect data across the entire image swath at once. Landsat 7, and previous Landsat satellites, had detectors that swept back-and-forth, like a whisk broom, as they collected data across the image swath.
