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.
An imposing, 38-foot long Tyrannosaurus rex fossil sold for a record $50.1 million at auction on Tuesday. But its purchase — likely by a private buyer — is being criticized by paleontologists and other scientists.
Wally Funk, a trailblazing aviation pioneer who was denied the opportunity to become a Nasa astronaut and half a century later became the oldest woman to travel into space, has died aged 87.
Within minutes of walking on a San Diego beach, marine ornithologist Tammy Russell found the feathered carcasses – one after another.
A well-worn expression among oceanographers and others who explore the watery depths of planet Earth is that we humans “know the surface of Mars better than our ocean floors.” Covering more than 70 percent of the world’s surface, oceans are notoriously difficult to study—not to mention pretty inhospitable to any creatures sans gills.
Sometime on Oct. 21 of last year, high above the Arctic Circle, a lone missile shot skyward from a Russian island.
‘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.
