Landsat 9 has opened its eyes.
The next-generation Earth-observation satellite, which launched on Sept. 27, snapped its first photographs of our planet on Oct. 31, NASA and the U.S. Geological Survey (USGS) introduced on Friday (Nov. 5).
The two companies, which work collectively on Landsat 9, have launched the preliminary imagery. It depicts the Florida Panhandle; Detroit and its surrounding space; Navajo Country in northern Arizona; the excessive Himalayas; and the Kimberley area of Western Australia.

“Landsat 9’s first images capture critical observations about our changing planet and will advance this joint mission of NASA and the U.S. Geological Survey that provides critical data about Earth’s landscapes and coastlines seen from space,” NASA Administrator Bill Nelson said in a statement.
“This program has the proven power to not only improve lives but also save lives,” Nelson added. “NASA will continue to work with USGS to strengthen and improve accessibility to Landsat data so decision makers in America — and around the world — better understand the devastation of the climate crisis, manage agricultural practices, preserve precious resources and respond more effectively to natural disasters.”
As its name suggests, Landsat 9 is the ninth satellite in the Landsat program, which has been studying our planet from orbit since 1972. It’s just the eighth to reach orbit, however; Landsat 6 was lost to a launch failure in 1993.
Landsat 9 will work together with the similar Landsat 8, which launched in 2013, to image the entire Earth once every eight days. The new satellite is replacing the aging Landsat 7, which lifted off in 1999. And this is a big upgrade. For example, Landsat 9 can differentiate more than 16,000 shades of a given color of light, compared to just 256 for Landsat 7, NASA officials said.
Landsat 9 has two Earth-imaging instruments. One detects thermal radiation, which will allow researchers to track surface temperatures, and the other picks up visible, near-infrared and shortwave-infrared light in nine different wavelengths, NASA officials said.
NASA is currently checking out Landsat 9 and its instruments, systems and subsystems, a process expected to take 100 days. In January, the space agency will hand mission operations over to the USGS, which will make the satellite’s images freely available to the public at its Landsat website.
“The information and pictures from Landsat 9 are increasing {our capability} to see how Earth has modified over many years,” Karen St. Germain, director of NASA’s Earth Science Division, said in the same statement. “In a altering local weather, steady and free entry to Landsat information, and the opposite information in NASA’s Earth observing fleet, helps information customers, together with metropolis planners, farmers and scientists, plan for the longer term.”
