New Earth-observing spacecraft sends first images of the planet

The latest Landsat spacecraft has sent back to Earth the first image of a changing world since it was launched into space two months ago.

Landsat 9 spacecraft, NASA The United States Geological Survey (USGS) was launched on September 27 from Van Denberg Air Force Base. California..

The first image to be released was taken on October 31st and Florida Panhandle, Detroit and its surroundings, and Navajo Country Arizona..

The US space agency has also released images of the High Himalayas and Kimberley regions of Western Australia as part of a photo of this first round from space.

This is the ninth Landsat satellite to continue the program, which started in 1972, and will work with Landsat 8 to image the entire planet every eight days.

NASA and USGS have released their first photo set on the Landsat 9 satellite since its launch in September. The city of Kathmandu, Nepal, shown in the lower left of this Landsat 9 image, is located in a valley south of the Himalayas between Nepal and China. In the upper center of this image, you can see the glacier and the lake formed by the meltwater of the glacier.

The satellite will be fully functional in January, taking thousands of images of the entire globe each week. The white sands of Pensacola Beach stand out in this Landsat 9 image of the Florida Panhandle in the United States, where Panama City can be seen under popcorn-like clouds.

In the western United States, in places like Navajo Nation, Landsat and other satellite data help people monitor drought conditions and manage irrigation water, as seen in this Landsat 9 image.

Landsat 9

Landsat 9 is the latest satellite in the Landsat series.

It continues its decades-long mission of recording the Earth’s surface and changing climate.

To reduce the risk of build-time and observation gaps, Landsat 9 largely duplicates its predecessor, Landsat 8.

Landsat 9 extends the ability to measure changes in the Earth’s surface on a large scale.

This is “a place where we can separate the causes of human and natural changes,” the USGS said in a statement.

Therefore, Landsat 9 provides an important element in our international strategy for monitoring global health and condition.

“Landsat users now have access to more frequent observations (every 8 days using two satellites).”

Applications such as weekly deforestation alerts, water quality monitoring and crop status reports are now viable.

According to NASA, the newly acquired images provide a “preview of how missions can help people manage important natural resources and understand the effects of climate change.”

They will be added to the existing 50-year data record, and Landsat 9 will work with Landsat 8 launched in 2013 to cover a wide range of the globe.

“The first image of Landsat 9 captures important observations about the changing planet,” said NASA administrator Bill Nelson.

“This program has a proven power to not only improve lives, but also save lives.

“NASA will continue to work with the USGS to enhance and improve access to Landsat data, helping decision makers in the United States and around the world better understand the devastation of the climate crisis,” he added. rice field.

By explaining it, leaders and experts can “manage agricultural practices, conserve valuable resources and respond more effectively to natural disasters”.

These first light images show different environments.

They add a wealth of data to help the USGS and other professionals monitor crop health and manage irrigation water.

The new images also provided data on the changing landscapes of the Himalayas in High Mountain Asia and the coastal islands and coastlines of northern Australia.

Landsat 9 is similar in design to its predecessor, Landsat 8. Landsat 8 was launched in 2013 and is in orbit, but with some improvements.

The new satellite will send data back to Earth with higher resolution, allowing it to detect more subtle differences, especially in dark areas such as water.

For example, Landsat 9 can distinguish over 16,000 shades of color for a particular wavelength. The exchanged satellite, Landsat 7, detects only 256 colors.

In this Landsat 9 image in both Detroit, Michigan and Windsor, Ontario, sediments are swirling around Lake Erie and Lake St. Clair. The Great Lakes serve as a source of freshwater, recreational activities, transportation and habitat in the upper Midwestern United States, and water quality remains a high priority.

The Great Lakes serve as a source of freshwater, recreational activities, transportation, and habitat in the upper Midwestern United States, and water quality remains a high priority.

This increased sensitivity allows Landsat users to see more subtle changes than ever before.

“The first light is a big milestone for Landsat users. It’s the first chance to actually see the kind of quality Landsat 9 offers. And they look great,” said Jeff Massek NASA’s Landsat at the Goddard Space Flight Center. 9 Project scientists said.

“Using Landsat 9 in conjunction with Landsat 8 gives us this wealth of data and allows us to monitor changes in our home planet every eight days.”

Landsat 9 includes two image capture devices to help you image the Earth.

One is the Operational Land Imager 2 (OLI-2), which detects visible, near-infrared, and short-wave infrared light of nine wavelengths.

The other is a thermal infrared sensor 2 (TIRS-2), which detects thermal radiation of two wavelengths and measures the surface temperature of the earth and its changes.

Landsat 9 has two devices designed to work together to capture a wide range of wavelengths.

According to NASA, these devices provide Landsat 9 users with important information about crop health, irrigation use, water quality, wildfire severity, deforestation, glacial retreat, and urban expansion.

“Landsat 9 data and images expand our ability to see how the Earth has changed over decades,” said Karen Saint-Germain, director of geosciences at NASA’s headquarters in Washington. Says.

“In the face of climate change, continuous and free access to Landsat data and other data from NASA’s Earth observation fleet is a way for data users such as city planners, farmers, and scientists to plan for the future. It will help. “

The Landsat 9 team will conduct a 100-day checkout period to test all systems, subsystems and tune sensors before they go into full operation in January.

When the test is complete, the USGS will operate Landsat 9 with Landsat 8 to combine the two satellites and collect approximately 1,500 images of the Earth’s surface covering the Earth every eight days.

“The first incredible photo from Landsat 9 satellite is science-based on key issues such as water use, the effects of wildfires, coral reef degradation, glacier and ice shelf retreat, and tropical deforestation. You can get a glimpse of the data that will help you make a decision, “said Dr. David Applegate, Deputy Director of USGS.
