It’s not arrogance — it’s just perspective. When everyone else is looking up, astronauts are looking down. And when what we’re looking for is a meteor shower, to say that the folks up at the International Space Station had the best seats in the house would be something of an understatement.
If you’re among the 80 percent of the world’s population living in an area with such extreme light pollution that you can’t see the stars, you probably couldn’t catch much of a show this past weekend when the Perseids made an appearance. But rest assured that no matter where you were on Earth, there’s no way that you could’ve gotten as good of a look as the folks miles above our planet’s surface.
Without any cloud cover to worry about or other pesky conditions to obscure their view, the folks aboard the ISS decided to set up an extremely sensitive, high-definition camera in the Window Observational Research Facility. And needless to say, it captured some pretty remarkable footage.
Beginning August 10, the ISS crew began seeing a bit of action from the Perseid shower, and before that, the project caught a meteor from the Delta Aquarids flying over the Pacific Ocean at the end of July. And while there’s plenty of aesthetic value in these images, scientists are gleaning valuable information from the captures as well.
For example, by analyzing the wavelengths of light the meteors emit as they burn, scientists can gather data about their composition, and by extension, their origin. Sure, it’s also possible to determine some of this information from Earth, but as Discover Magazine points out, “there is less atmospheric noise distorting spectra observations recorded in space.” Moreover, the high-tech camera the ISS crew set up is capable of discerning very fine grains of dust that wouldn’t otherwise be visible to us Earthlings.
There’s actually plenty of footage from the Perseids from the ISS, as the station orbits the globe a total of 16 times a day, making for plenty (nine hours, to be exact) of observation time.
So if you missed the meteor shower IRL, this footage may be better anyway.
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.
