The last time I saw Laura Grego was in a tent in a baking field on the Welsh borders in May. The conversation on stage ranged from the dangers of space debris to how the law of the sea might pertain to outer space; from our sense of the sacred to our interplanetary futures. At one point Grego, a physicist, said intently, “People have to be aware of what is happening in space. Public knowledge has to catch up.” Three weeks later, SpaceX launched on the stock exchange, temporarily making Elon Musk the world’s first trillionaire.
So, I ask her now, what is it that we should all know? Well, she says, the average person’s experience of space is about to change. If, so far, that has been “looking at the stars and being full of wonder, full of connection with the universe”, perhaps noticing the occasional streaking object that was not a shooting star, now “there are plans for tens of thousands more satellites, which would really change your relationship with what you see in the sky”. SpaceX, specifically, has just applied to a federal regulator for permission to launch up to 1m of them.
Grego, who is now back in the US and speaking to me on screen from Cambridge, Massachusetts, has an unforced warmth and urgency, and a lack of self-aggrandisement in striking contrast to the gung-ho attitude that seems to accompany so much discussion of space. She became a physicist when she arrived at university and looked for the hardest thing she could find to study, so as to get her time’s worth (“a very midwestern perspective”). Then she became an observational cosmologist, which she found she loved. This merged with her other life as an activist (“anti-war, workers’ rights, racial justice – all the things important for a better society”) when she became research director of the Global Security programme at the Union of Concerned Scientists.
‘This would have been a wild dream a year ago,” says Andrea Ceccolini, standing on Arctic sea ice just a 4-mile snowmobile ride from the Inuit town of Cambridge Bay, northern Canada. To his left are sky blue ponds of meltwater created in the last few days by a sun that no longer sets in the high north summer. To his right, the sea ice is still a brilliant white, the light dusting of snow on top continuing to sparkle.
The US military said it killed four more people in a boat strike in the eastern Pacific ocean on Tuesday, marking the third deadly attack on vessels in the region in four days.
The astronauts aboard NASA's Artemis II have now traveled farther from Earth than any other humans in history, breaking the Apollo 13 record.
On February 26, 2025, a NASA probe called Lunar Trailblazer lifted off from Kennedy Space Center in Florida. Its mission was to map the water on the moon. But a day after launch, mission managers lost contact with the spacecraft, and it was never heard from again.
She navigated segregation to become an esteemed mathematician — and today, her work helps billions of people navigate the world.
The Nobel physics prize is awarded by the Royal Swedish Academy of Sciences and includes a prize sum totalling 11 million Swedish crowns ($1.2 million) that is shared among the winners if there are several, as is often the case.
