For the last two decades, the International Space Station (ISS) has been orbiting Earth some 250 miles above our heads. The modular facility is home to a rotating crew of astronauts who come to experience life in a unique environment while also conducting scientific research in microgravity conditions.
Almost 110 meters (356 feet) end to end — about the same length as a football field including the end zones — the ISS moves through space at around 17,000 mph, completing 16 Earth orbits a day, or about one every 90 minutes.
If the ISS passes over your neighborhood on a clear night, its bright appearance and high speed make it easy to spot with the naked eye. NASA offers tips on how to find out when it’s coming your way, so you can see it for yourself.
Some skywatchers go one step further and point powerful lenses toward the facility, capturing incredibly detailed shots of the station as it zips across the sky.
This week, NASA took to Twitter to highlight some of the best of these close-up images captured over the years by various photographers around the world, united in their fascination of the orbital outpost.
Wow! Check out these impressive #SpotTheStation photos from enthusiasts on the ground that show the orbiting lab up close and in detail. https://t.co/CBL3UN5HfB

They include this wonderful effort by Chris Hooker of the Newbury Astro Society in the U.K., with the image showing the entirety of the station with its solar panels clearly identifiable on either side of the central, habitable modules.
An absolutely superb image of #iss captured at 12.31 this morning by our very own Chris Hooker. 10in Newtonian, manually tracked. Anyone else suffering from overexposed heat rejection panels? #spotthestation @space_station https://t.co/zFPggYZLAo pic.twitter.com/QQoYVSWO7G

Steve Knight, also based in the U.K., tweeted this impressive shot of the ISS that he took early one evening in the spring of 2021.

This awesome effort by Sylvain Weiller shows the station turning slightly as it moves through the sky some 250 miles up.

U.S.-based Roger Craig Smith used a Canon 7D Mark II with a 400mm lens and 2X teleconverter to grab this image as the ISS passed over Los Angeles one evening a few years back.
Another #SpotTheStation night!
Here's the @Space_Station from a Canon 7DmkII with 400mm and 2X extender as it passed LA tonight.

Finally, we have this stunner from II+II Padawan, whose shot is so clear that it’s possible to identify both SpaceX’s Crew Dragon and Russia’s Progress 79 cargo spacecraft.
The International @Space_Station upcoming phase from 27th. From this angle very clear to see the #SpaceX Crew-3 Dragon and the Progress 79.#Astrophotography #ISS @zwoasi #Telescope @The_SolarSystem pic.twitter.com/zRGEpUWsoj

To find out more about life on the International Space Station, check out these videos made by astronauts who’ve visited the orbital outpost over the years.
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.
