Earlier this month, the European Space Agency (ESA) launched its newest Earth-observation satellite, known as Copernicus Sentinel-2C. Joining its siblings Sentinel-2A and B, it will take high-resolution images of the planet’s surface from its altitude of almost 500 miles, capturing some stunning views of lesser-seen parts of our world.
Now, the first images taken by Sentinel-2C have been released, including views over European cities, a stretch of the French coast, and the effects of the wildfires raging through California. “These initial images stand as a powerful testament to the success of this extraordinary mission,” said Simonetta Cheli, ESA’s director of Earth Observation Programmes, in a statement. “While Sentinel-2 will continue to serve Copernicus with distinction for years to come, we are already looking ahead as we develop the next chapter with the Sentinel-2 Next Generation mission.”
The satellite will be used for functions like tracking agriculture by looking for signs of crops or drought, monitoring water quality from space, and managing natural disasters like wildfires, floods, or volcanic eruptions. The effects of recent wildfires in California can be seen in two images below, which show natural color and false color versions of the area south of Los Angeles around the Airport fire, taken on September 12. The image on the left shows the spreading smoke, while the image on the right shows both active fires and areas that have already been burned.
With the first images in from the satellite, the engineers on the project will now spend the next three months calibrating the instruments to get even greater precision.
“We are thrilled to see the Copernicus Sentinel-2C already capturing such breathtaking images of Earth so soon after its launch,” said Constantin Mavrocordatos, Sentinel-2 Project Manager at ESA. “This is just the beginning of the incredible insights and detailed data it will provide, helping us better understand our planet.”
After 13 suborbital test flights and more than $15 billion in development costs, SpaceX's Starship has finally reached orbit. The 407-foot megarocket, the most powerful ever built, lifted off from Starbase, Texas, on Monday and delivered its first real payload on it's 14th attempt. The celebration came with an asterisk, though, since SpaceX had to cut the planned 10-hour mission to roughly three hours.

SpaceX is finally ready to give Starship its biggest test yet. The company says the massive rocket's 14th test flight is scheduled for September 22, when it will attempt to put the upper stage into Earth orbit for the first time. The launch is currently pending regulatory approval, with a 75-minute window opening at 7:15 a.m. CT.
Starship has 26 Starlink satellites to deliver
For decades, humanity has looked up at the Moon and wondered what it would be like to live on it. Think sprawling cities, factories, research centers, and permanent human settlements. Unfortunately, there is one fairly fundamental problem with that vision.
A new study published in Frontiers in Space Technologies argues that even the Moon's potentially enormous reserves of frozen water may be nowhere near enough to support city-sized populations sustainably. Researchers Martin Elvis and Jonathan McDowell estimate that the permanently shadowed regions near the lunar poles could contain roughly one billion tons of water. It sounds like an extraordinary amount until you put a million thirsty humans next to it.
