Landsat 9, a joint mission between NASA and the US Geological Survey launched earlier this 12 months, has collected its first gentle photos of the Earth. The photographs present distant coastal islands and inlets of the Kimberley area of Western Australia, Glaciers excessive within the Himalayas, Lake Erie, white sands of Pensacola Seaside and Florida and others.
A NASA launch stated, all the pictures, acquired on October 31 present a preview of how the mission will assist folks handle important pure assets and perceive the impacts of local weather change, including to Landsat’s unparalleled information file that spans practically 50 years of space-based Earth statement.
“Landsat 9’s first photos seize important observations about our altering planet and can advance this joint mission of NASA and the U.S. Geological Survey that gives important information about Earth’s landscapes and coastlines seen from area. This program has the confirmed energy to not solely enhance lives but additionally save lives,” stated NASA Administrator Invoice Nelson.
“NASA will proceed to work with USGS to strengthen and enhance accessibility to Landsat information so decision-makers in America – and world wide – higher perceive the devastation of the local weather disaster, handle agricultural practices, protect valuable assets and reply extra successfully to pure disasters,” he added.

Landsat 9 is analogous in design to its predecessor, Landsat 8, which was launched in 2013 and stays in orbit, however options a number of enhancements. The brand new satellite tv for pc transmits information with increased radiometric decision again all the way down to Earth, permitting it to detect extra delicate variations, particularly over darker areas like water or dense forests.
For instance, Landsat 9 can differentiate greater than 16,000 shades of a given wavelength colour; Landsat 7, the satellite tv for pc being changed, detects solely 256 shades. This elevated sensitivity will enable Landsat customers to see rather more delicate modifications than ever earlier than.
“First gentle is an enormous milestone for Landsat customers – it is the primary probability to actually see the type of high quality that Landsat 9 offers. They usually look unbelievable. When we now have Landsat 9 working in coordination with Landsat 8, it’ll be this wealth of information, permitting us to observe modifications to our residence planet each eight days,” stated Jeff Masek NASA’s Landsat 9 undertaking scientist at Goddard House Flight Middle.
