Space travel is dangerous. Could genetic testing and gene editing make it safer?
Long-distance space travel can wreak havoc on human health. There’s radiation and microgravity to contend with, as well as the psychological toll of isolation and confinement. Research on identical twin astronauts has also revealed a slew of genetic changes that happen when a person spends a year in space.
That’s why some bioethicists are exploring the idea of radical treatments for future astronauts. Once we’ve figured out all the health impacts of space travel, they argue, we should edit the genomes of astronauts ahead of launch to offer them the best protection. Some have even suggested this might result in the creation of an all-new species: Homo spatialis.
If this is starting to sound a bit like sci-fi, that’s because it mostly is, for now. But there are biotechnologies we can use to help space travelers now, too.

MIT Technology Review Narrated: How generative AI could reinvent what it means to play
Open-world video games are inhabited by vast crowds of computer-controlled characters. They make virtual worlds feel lived in and full.
After a while, however, the repetitive chitchat (or threats) of a passing stranger forces you to bump up against the truth: This is just a game.
It may not always be like that. Generative AI is opening the door to entirely new kinds of in-game interactions that are open-ended, creative, and unexpected. Future AI-powered NPCs that don’t rely on a script could make games and virtual worlds deeply immersive.
This is our latest story to be turned into a MIT Technology Review Narrated podcast. In partnership with News Over Audio, we’ll be making a selection of our stories available, each one read by a professional voice actor. You’ll be able to listen to them on the go or download them to listen to offline.
We’re publishing a new story each week on Spotify and Apple Podcasts, including some taken from our most recent print magazine. Just navigate to MIT Technology Review Narrated on either platform, and follow us to get all our new content as it’s released.

The big story
The race to fix space-weather forecasting before next big solar storm hits
As the number of satellites in space grows, and as we rely on them for increasing numbers of vital tasks on Earth, the need to better predict stormy space weather is becoming more and more urgent.
Scientists have long known that solar activity can change the density of the upper atmosphere. But it’s incredibly difficult to precisely predict the sorts of density changes that a given amount of solar activity would produce.
Now, experts are working on a model of the upper atmosphere to help scientists to improve their models of how solar activity affects the environment in low Earth orbit. If they succeed, they’ll be able to keep satellites safe even amid turbulent space weather, reducing the risk of potentially catastrophic orbital collisions. Read the full story.
