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.

Axiom Mission 4 cleared for launch
The four-member crew of Axiom Space's AX-4 mission is finally a 'go' for launch. NASA has approved to proceed after investigating a leak in the Russian segment of the International Space Station, which had caused several days of delays. 'I believe what they've come back and said is we understand where it's coming from, we understand the rate at which it's happening,' said Keith Cowing of NASA Watch. 'It changes very little. We're safe to go ahead with this.' The AX-4 crew, led by former NASA astronaut Peggy Whitson, will spend 14 days aboard the ISS, conducting approximately 60 scientific and technological experiments. This mission also marks a historic milestone, as it will be the first time astronauts from India, Hungary, and Poland will visit the orbiting lab. Cowing, a former NASA employee and longtime space program analyst, highlighted the importance of commercial missions like AX-4, stating, 'NASA always is looking for extra help to do get part of an astronaut's time without paying for the full astronaut. It gives NASA another option to do some of its own stuff. But, at the same time, it allows the private sector to start bringing stuff up.' Axiom Space is working on building its own commercial space station, with the aim of gaining experience through missions like AX-4. The launch is currently scheduled for no earlier than Wednesday morning at 2:31 a.m. Click here to download our free news, weather and smart TV apps.

How to see Mercury, the moon and the Gemini twins pass close together in the night sky this week
When you buy through links on our articles, Future and its syndication partners may earn a commission. During the final week of June and continuing into the first week of July, we'll have a fair chance at sighting Mercury, the innermost planet to the sun. Many people have never noticed that Mercury swings rapidly back and forth relative to the sun in our sky, while moving along in an orbit scarcely more than half as far from the sun as Venus. This fastest-moving and smallest major planet (only 1.4 times wider than the moon) orbits the sun 4.15 times a year, but from our own moving vantage point it appears to go around only 3.15 times. Each year it makes about 3.5 swings into the morning sky and as many times into the evening — excursions of highly unequal character because of its eccentric orbit and the varying angles from which we view it. Typically, as seen from the Northern Hemisphere for after-sunset views of Mercury, its spring treks into the evening skies prove to be the best. Although it did not occur officially within the spring season, this year's first evening apparition that ran from Feb. 23 through March 15 was an excellent one, since for a few days centered around the date of its greatest elongation from the sun (March 8), Mercury set just after the end of evening twilight against a dark sky. Now, this speedy, rocky little world is again available to view in the evening sky, although on this occasion, not a "spring" apparition, but more like early summer, encompassing the timeframe from June 20 through July 11. This time, Mercury's greatest elongation from the sun will come on July 4. During this current evening apparition, Mercury's climb out of the west-northwest horizon comes at a steeper angle and yet it will attain an altitude essentially as high above the setting sun as it did in late February and early March. What is different this time around is that it is now early summer, not late winter. So, from mid-northern latitudes, the duration of evening twilight is longer by about 30 minutes. As such, unlike in early March, we cannot hope to glimpse Mercury against a dark sky. However, during its evening appearances, Mercury always appears brightest in the days leading up to its greatest elongation. On June 20, it shone at magnitude -0.2, brighter than the similarly-hued star Arcturus, the second brightest behind Sirius as seen from northern latitudes. By July 3 it will have faded to a still respectably bright magnitude of +0.5, which would rank it among the top ten brightest stars in the sky. So, it should not be too difficult to sight against the twilight sky, low in the west-northwest about 45 minutes to one hour after sunset. And during this week, we'll have some help in identifying it thanks to some other celestial landmarks. TOP TELESCOPE PICK: Want to get close-up views of planets in the night sky? The Celestron NexStar 4SE is ideal for beginners wanting quality, reliable and quick views of celestial objects. For a more in-depth look at our Celestron NexStar 4SE review. On Tuesday evening, June 24, Mercury will form a nearly straight line with two bright stars; the Gemini Twins, Pollux and Castor. Going from right to left, the distance between Castor and Pollux measures 4.5 degrees. If you were to draw an imaginary line between these two stars and extend it another 6.5 degrees to the left, you will come to Mercury. Or, put another way, if you make a clenched fist and hold it out at arm's length, that will measure roughly 10 degrees. The distance from Mercury to the star Castor (going from left to right) should measure a bit more than one fist width, or about 11 degrees. In addition, keep in mind that Mercury will appear much brighter than either Pollux and Castor. On this night, Mercury will shine at zero magnitude, while Pollux will appear only about a third as bright at magnitude +1.1 and Castor only about one quarter as bright at magnitude +1.6. So, while it's likely that you'll be able to see Mercury with your naked eye, Pollux and Castor will likely be more difficult to see amidst the twilight glow. So be sure to have a pair of binoculars on hand to help you see these Twin Stars teamed up with Mercury. Remember: if you're looking for a telescope or binoculars to observe Mercury or any other night sky event, our guides for the best binoculars deals and the best telescope deals now can help. Two evenings later, on Thursday, June 26, another celestial wanderer will appear on the scene — the moon. Only a little over 1.5 days past the new moon phase, it will appear as a very narrow, wire-thin crescent, a mere 3 percent illuminated by the sun. Here again, binoculars will prove most beneficial in helping to find not only Pollux and Castor, but this exceedingly slender lunar sliver. But what an amazing scene awaits you if you are successful in making a sighting. On this evening, Pollux and Castor will be pointing directly at the moon and the gap separating this trio will be equidistant: From Castor to Pollux will measure 4.5 degrees and from Pollux to the moon will measure another 4.5 degrees; a celestial triple play. But don't forget Mercury. It will be shining about 4.3 degrees to the left and ever-so-slightly above the moon. In short, four prominent celestial objects — the moon, a bright planet and two bright stars — stretched out across a little more than a dozen degrees of the west-northwest sky. A celestial quadruple grouping! But please keep in mind that in many parts of the country, June has a reputation for being a sultry, hazy and humid month. So unfortunately, visibility of objects so low to the horizon might hinder seeing this "celestial summit meeting." But if your local sky is clear and transparent, try not to miss it, for gatherings like this of the moon accompanied by bright stars and planets are unusual and wonderful sights. Mercury will quickly move away from the Gemini Twins in the days following June 26, and will rapidly fade after July 4, transitioning into the morning sky on July 31. On balmy mornings in August, get up early to see this elusive planet climbing almost straight up above the point of sunrise. By Aug. 19, about an hour before sunrise, it will reach its highest, with the "dynamic duo" of Venus and Jupiter, respectively 15 and 22 degrees higher still. Pollux and Castor will also be nearby and on the mornings of Aug. 20 and 21, the moon will again join in too! Mark your calendars ...

New Vera Rubin Observatory discovers 2,000 unknown asteroids within 10 hours
While about 20,000 previously unknown asteroids are discovered every year by telescopes around the world and spacecraft in orbit, the first images by the new Vera C. Rubin Observatory revealed 2,000 undiscovered asteroids taken during about 10 hours of scanning the night sky. There are dozens of telescopes on Earth and satellites in the sky searching for new objects that might pose a threat to our planet. The National Science Foundation-Department of Energy's Vera C. Rubin Observatory in Chile was not built to be an all-in-one asteroid detector. Still, as a fast-moving, machine-learning facility, the observatory is the most effective at spotting interstellar objects passing through the solar system, according to the NSF. First Celestial Images From 10-Year Project Photographing The Universe Released The Vera C. Rubin Observatory took two decades to complete and was named after the American astronomer credited with the first evidence of dark matter. Later this year, work will begin creating the largest astronomical movie yet of the Southern Hemisphere, known as the Legacy Survey of Space and Time, using a camera of the same name. The LSST Camera is the largest digital camera in the world with a field of view of about 45 times the area of the full Moon in the night sky. One image would need 400 Ultra HD TV screens to display. On Monday, the Rubin team revealed the first images taken by the observatory, including parts of the Milk Way and beautiful spiral galaxies. Among the first images were more than 2,000 asteroids, including seven near-Earth asteroids previously undocumented in NASA's Small-Body Database. A timelapse video shows how the Observatory's powerful camera tracked the moving dots in the sky. On night one, nearly 1,000 asteroids were found. By the end of a week of observations lasting a few hours each night, the observatory had found more than 2,100 never-before-seen in our solar system in just a fraction of the night sky it will eventually scan. Who Was Vera Rubin? Dark Matter Astronomer's Legacy Continues Through New Observatory These new asteroids, including seven near-Earth asteroids, pose no danger to our planet. According to the NSF, Rubin will discover millions of new asteroids within the first two years of article source: New Vera Rubin Observatory discovers 2,000 unknown asteroids within 10 hours
