Final photo from iconic US satellite shows how Las Vegas has 'doubled' in size over the last 25 years
QUICK FACTS
Where is it? Las Vegas, Nevada [36.10457930, -115.1448612]
What's in the photos? Aerial shots taken at the start and end of a satellite's operational lifespan
Which satellite took the photos? Landsat 7
When were the photos taken? July 4, 1999 and May 28, 2024
The last image captured by the recently decommissioned Landsat 7 satellite shows the sprawling mass of Las Vegas flowering in the heart of the Mojave Desert. The final photo also mirrors one of the satellite's first-ever shots, highlighting how "Sin City" has rapidly expanded during the iconic spacecraft's 25-year lifespan.
Landsat 7 is an Earth-observing satellite co-owned by NASA and the U.S. Geological Survey (USGS) that orbits our planet roughly every 99 minutes. It was launched on April 15, 1999, and has since taken more than 3.3 million images of Earth's surface, covering almost every square inch of the globe.
On June 4, the satellite received its final transmission from operators, marking the official end of its mission after a year-long decommissioning process that took the spacecraft out of the path of other satellites before it ran out of fuel. Landsat 7 will now drift in space for around 55 years before eventually reentering and burning up in the atmosphere, according to a USGS statement.
The satellite's final image was captured on May 28, 2024. It shows the Las Vegas metropolitan area, including towns such as Henderson, Paradise and Spring Valley, sprawled across the Nevada desert.
The final image was taken from the same distance and angle as one of the satellite's first shots of the city, taken on July 4, 1999. Comparing the two side-by-side shows how much the city has expanded — nearly doubling in size.

Between 2000 and 2023, the population of the Las Vegas metropolitan area went from 1.38 million to 2.33 million, which is an increase of around 69%, according to USGS. In 2025, an estimated 2.4 million live in the area.
Lake Mead, an artificial reservoir of the Colorado River created by the Hoover Dam, can also be seen in both satellite images. The lake is noticeably smaller in the latest image, possibly due to increased water consumption in the region it serves or the effects of human-caused climate change. However, the lake's size naturally fluctuates, both seasonally and annually, making it hard to tell how it is being impacted by anthropogenic factors, according to NASA's Earth Observatory.
Landsat 7 is the seventh satellite in the Landsat program, which has been continuously capturing images of Earth's surface since 1972. It was a serious upgrade from previous iterations and was particularly good at photographing urban areas, which was its primary focus.
The spacecraft played a major role in the development of mapping services, including Google Maps, and also captured unique perspectives of some iconic moments in recent history, including the 9/11 terror attacks, Hurricane Katrina, and the Deepwater Horizon oil spill.
The satellite was only designed to operate for five years, but it has far exceeded this target, despite suffering a significant instrument failure in 2003, which was later fixed. NASA previously reconsidered refueling the satellite in orbit to extend its lifespan, but this first-of-its-kind maneuver was never attempted.

There are now only two operational Landsat satellites circling our planet: Landsat 8, which has been in orbit for more than 12 years; and Landsat 9, which launched in September 2021.
The 10th Landsat satellite, named Landsat Next, was supposed to be launched by 2031. However, its funding is now uncertain thanks to the drastic cuts to NASA's budget proposed by the Trump administration, and mission experts are now "assessing alternate mission architectures," according to the Landsat Next homepage.

NASA's TOMEX+ rockets to study turbulence in Earth's mesosphere
One of the three rockets for the TOMEX+ mission sits on a launcher at Wallops Flight Facility in Virginia. Photo by Danielle Johnson/NASA Aug. 20 (UPI) -- NASA is planning to launch TOMEX+ rocket mission to study the turbulence where Earth's atmosphere ends and outer space begins sometime over the next two weeks. The earliest the agency expects to launch the three sounding rockets is Saturday, with the launch window closing Sept. 3, NASA announced Wednesday. The launch window has been repeatedly pushed back, this time due to high sea states in the rocket recovery area from Hurricane Erin. Sounding rockets are those that can be aimed to reach the Earth's mesopause, an area of the atmosphere that's too high for weather balloons and too low for traditional satellites to reach. The mesosphere is the coldest layer of Earth's atmosphere and is the place where weather patterns on the planet can transfer energy into space, creating turbulence that can affect satellites. NASA will use three sounding rockets to carry out the study, the first two launching within about a minute of each other. They will release vapor that will help scientists on the ground map wind patterns in the mesosphere. The third rocket will then use a lidar -- light detection and ranging -- device to send out pulses of light to detect sodium atoms in the mesosphere. The sodium comes from tiny grains of dust that enter the Earth's atmosphere from space. The lidar will allow scientists to further map the mesosphere's density and motion over time. "Together, the TOMEX+ payloads will provide the clearest 3D view yet of turbulence at the edge of space, improving our understanding of high-altitude cloud formation, satellite drag and even atmospheric processes on other planets," NASA said in a blog post on the project. NASA will launch the rockets from Wallops Flight Facility on Wallops Island, Va. The project is led by Jim Clemmons, a professor of physics and astronomy at the University of New Hampshire.

See video of Hurricane Erin from the International Space Station
As Hurricane Erin hovered over the Atlantic Ocean, the first hurricane of the 2025 Atlantic hurricane season was spotted from above by a camera on the International Space Station. The SpaceTV-1 camera system, which livestreams up to 4K resolution footage of Earth from space, captured Hurricane Erin at 12:29 p.m. EDT Wednesday as it moved north of the Caribbean, a few hundred miles off the U.S. East Coast. The camera is mounted on the International Space Station in low Earth orbit, according to Sen, the company that began streaming space footage late last year. NASA on Tuesday also released video of Hurricane Erin as seen from the ISS at a different angle. Erin rapidly intensified over the weekend, strengthening from a Category 1 to a Category 5 hurricane in around 24 hours, NASA said Wednesday, sharing a 3D model of the storm. It has since weakened as it churned over the Atlantic, but forecasters warned it would bring on life-threatening surf and rip currents in several states. Mandatory evacuations were ordered for Hatteras Island and Ocracoke Island in the Outer Banks of North Carolina ahead of the expected Sundby contributed to this report.
