Five Things We Learned From NASA's First Interactive Twitch Stream From Space
Feb. 16, 2025 4:33 a.m. PT
When you think of livestreaming service Twitch, you might associate it with gamers, influencers and even politicians playing video games live for all to see.
But on Wednesday, Twitch leaped into space, conducting a first-of-its-kind live stream with a NASA astronaut from the International Space Station.
The stream took place on NASA's official Twitch channel and featured one astronaut currently in space and another who's back on Earth, with both engaging with viewers live on the platform.
The currently-in-space host was NASA astronaut Don Pettit, who joined the ISS crew back in September as part of the Expedition 72 launch. Pettit is known for the amazing space photos he frequently posts on social media.
He was joined by NASA astronaut Matt Dominick, who's currently on Earth after returning with Crew-8 in October after being delayed by Hurricane Milton. Dominick has also taken some showstopping pictures from the ISS.
Here are five things we learned from NASA's live Twitch stream this week.
Coming back from space sucks
The astronauts answered questions from fans and students all around the US, at one point addressing what it was like to return to Earth after spending time in space.
Pettit mentioned that it takes about a day for him to achieve "stomach awareness," which he described as a polite way of saying "puking your guts up." Dominick echoed this sentiment.
Space photography has its difficulties
Dominick spoke about how fast the ISS moves around Earth, and how it affects the time he has to take photos.
In one instance, he was tasked with taking a picture of Hurricane Milton from space, and said he only had about 30 seconds to do it because the ISS moves "ludicrously fast."
Pettit joined the stream about 10 minutes in and the two astronauts immediately began to discuss the intricacies and difficulties of taking photographs from space.
The two talked about taking thousands of pictures particularly thunderstorms to get pictures of red sprites, which are luminous flashes that appear above active thunderstorms.
Both have been successful in photographing red sprites in the past but have been more successful in photographing blue jets, a type of lightning that shoots upwards from thunderstorms.
Pettit also showed off his photography setup, which includes a Nikon Z9 with a variety of lenses on a heavy-duty mount.
Coffee is still important in space
As Pettit attempted a physics demonstration with a yo-yo, the ISS lost contact with its satellite, ending the astronaut's brief Twitch stream debut.
Pettit is the designer of the ISS's capillary cup, which allows astronauts to drink coffee (and enjoy its pleasant fragrance) on the ISS without the hot beverage escaping.
Pettit's desire to drink in space without using the awkward bag-and-straw method inspired the idea.
According to Dominick, this wasn't an assigned task. Pettit invented it on a whim.
Per Dominick, Pettit often says that "today's coffee is tomorrow's coffee" since most water, including waste like urine, is recycled and reused over and over again. Over 90% of water waste is recycled to be reused again.
