Northrop Grumman has launched a private satellite-servicing mission to attach life-extending "jetpacks" to aging communications satellites in geosynchronous orbit. "It's the second satellite-saving mission to launch this month, all part of a growing, money-saving effort to keep spacecraft running as long as possible," reports Phys.org. From the report: Launched by SpaceX, Northrop Grumman's mission robotic vehicle -- dubbed MRV -- and its jetpacks will spend the next year angling into the proper orbit 22,300 miles (36,000 kilometers) above Earth. Hundreds of satellites orbit at this so-called geosynchronous orbit, where they match the speed of Earth's rotation and keep to the same part of the sky for continuous coverage. Once in place by mid-2027, the minivan-sized spacecraft will use its 10-foot (9-meter) arms to attach a jetpack to an aging communication satellite. Then it will zip off to two more satellites in need.
For its debut flight, the spacecraft was accompanied by three electric-propelled jetpacks that peeled away separately following liftoff. Like the MRV, the jetpacks will use their own xenon gas thrusters to get to the desired orbit. Once in place, the jetpacks will wait for the robot to grab them, one at a time, and plug them into their designated satellites. Each jetpack -- the size of a washing machine -- will provide the necessary oomph for an out-of-gas satellite to keep operating for several more years instead of retiring. If it works, it will be a boon for satellite operators SES of Luxembourg and Optus of Australia, saving them millions of dollars in replacement costs.

Ludwig Göransson’s meticulous score uses instruments of the era to create an earthy, raw and bleak soundscape, but it merely supports the portrayal of an uncomplicated hero
A few weeks ago I came across a video of Professor Armand D’Angour, associate professor of classics at Oxford university. He explained how, through groundbreaking research involving fragments of melody and rhythms found on papyrus and stone and the reconstruction of ancient instruments, it is now possible to hear for the first time in 2,000 years what ancient Greek music would have sounded like.
Given Ludwig Göransson’s beautiful theme for the aulos (an ancient double-barrelled flute) in Christopher Nolan’s latest blockbuster, The Odyssey, and his reputation for dedicated research into his subject matter, it seems very likely that he too has heard these calls from the ancient past.

In her first 48 hours as energy secretary, Miatta Fahnbulleh was left in no doubt about the thorny policy decision at the top of her in-tray. Protesters from Fossil Free London met her outside her new offices dressed as firefighters holding placards reading: “We’re already putting out fires, don’t start new ones.”
The MP for Peckham – a radical economist who is outspoken about the climate crisis – is a surprising choice as secretary of state for energy and net zero for those who believe the speculation in Westminster that Andy Burnham wants to approve new oil and gas drilling in the North Sea.

After six books, three seasons of television and a film-length finale, Heartstopper has come to an end. Often dubbed the most wholesome show on TV, Netflix’s adaptation of Alice Oseman’s young adult LGBTQ+ graphic novel series, which itself began life as a web comic, is a legitimate cultural phenomenon, turning its two leads – Kit Connor and Joe Locke – into household names, while racking up tens of millions of views. In print, meanwhile, the Heartstopper series has sold over 10m copies worldwide, including about 1.3m in the UK alone.
Yet these figures only tell one side of the story of Heartstopper’s impact. At the queer and feminist bookshop where I work part-time in Sheffield, the young people who come in are immediately drawn to copies of Oseman’s books, and often take pictures of the now permanent window display depicting Nick and Charlie, the couple at the story’s heart. I see young queer people’s faces light up when they see we have the book in stock, even though they probably already have a copy at home.

George Lutkenhaus and his family were rushing to the airport. There was a plane to catch and traffic was bad. Inside the car was a tense silence. In the back, a teenager, minding his own business, AirPods in, seemingly oblivious. Wife Tricia turned to George. “Are you OK?” she said.
“No, I am not OK!” he replied. “What just happened there was not normal! And he’s just sitting there in the back … ”

Hands down the hottest ticket in London this summer is the musical Pride at the National Theatre, which is booked solid until the end of its run in September and will presumably transfer to the West End after that. There are lots of gay shows doing well at the moment: I saw Oh, Mary! for the second time this week when the show’s creator, Cole Escola, came over from New York to resume the title role, and Operation Mincemeat keeps going and going. But both those shows are tonally rather than politically gay. Pride, which is adapted from the 2014 film and had modest commercial success when it came out, is a different kettle of fish and I’m curious as to why it’s flown now.
I should say up front I haven’t seen the show (can’t get a ticket!). But this week, as I watched my timeline continue to fill up with effusive praise and lots of crying about the musical, I went back to the film. It’s a strange time to watch it, in a news cycle in which issues around sexuality in public life and old views about gay rights have surfaced to yank us back to earlier times. The death of the US senator Lindsey Graham triggered widespread speculation about what, exactly, Donald Trump held over him and gave rise to a lot of gay jokes pulled out of the deep freeze.

The stark contrast between Donald Trump’s nuclear deal with Saudi Arabia and his nuclear demands for Iran would be comical if not so tragic. Trump has handed the Saudis the same nuclear options he swore Iran would never have.
To make matters worse, Trump seems to have offered the Saudis this sweetheart deal to make amends for his disastrous war of choice with Iran. Meanwhile, he continues to bomb Iran in a push to open the strait of Hormuz, which was not closed until Trump launched his counterproductive war.

‘I am acutely conscious,” said Andy Burnham outside 10 Downing Street on Monday, “that I am the sixth person in the last 10 years to walk up this street.” It was good to hear him say it because, beneath all the cabinet gossip and rune-reading, there is a feeling of terror about the immediate future and also about ourselves, the electorate. Is this who we are now? Wildly enthusiastic one minute, seething the next; as passionate about the change we want as we are convinced that those who promise it are incapable of enacting it?
It is perhaps not surprising that Anton Jäger’s recent book, Hyperpolitics: Extreme Politicization without Political Consequences, is being read by Labour watchers and leftwing thinkers. As the New York Times wrote, it’s “among the best and most dazzling efforts to model the political present in all its maddening strangeness”. Still, I think Jäger was surprised to have his honeymoon interrupted so I could interview him about it. Life comes at everyone quite fast in a hyperpolitical age.
