Solar array delay

On June 7, Electrek reported that an uncrewed SpaceX Dragon CRS-22 cargo ship successfully delivered two out of six International Space Station (ISS) Roll-Out Solar Arrays (iROSA). Astronauts were due to install the two iROSA on spacewalks on June 16 and June 20, but their first attempt hit some snags.

Spaceflight Insider explains what happened on Wednesday:

NASA astronaut Shane Kimbrough and European Space Agency astronaut Thomas Pesquet, both members of the seven-person Expedition 65 ISS crew, ventured outside the outpost June 16, 2021, for a spacewalk, officially called US EVA-74, which was tasked with installing the first of two ISS Roll-Out Solar Arrays, also called iROSA.

About midway through the 7-hour, 15-minute outing, Kimbrough noticed the display on the Displays and Control Module on his suit appeared to be off, requiring him to return to the Quest airlock to perform a “warm restart.” While this issue was resolved, it burned through nearly 45 minutes, time that could have been used to troubleshoot an alignment issue with the iROSA that later cropped up once the two astronauts began installing it on the P6 truss.

The two astronauts will resume – and hopefully be able to complete – installation of the solar arrays on Sunday.

Each IROSA will produce 20kW of additional power for the ISS, or a total of 120kW. According to NASA, once all six solar arrays are deployed, the ISS’s solar power is expected to be boosted to around 215 kW, because portions of the old solar arrays will still produce around 95kW.

Lower-emissions EV batteries

Irvine, California-headquartered Enevate, which develops and licenses advanced battery technology for electric vehicles, announced it has achieved up to 27% reduction of emissions during manufacturing with its XFC-Energy technology.

Enevate announced its fourth-generation XFC-Energy technology last year. It says it provides a path to produce extreme fast-charge EV batteries at low cost and high-volume production. The company is currently working with multiple automotive OEMs and EV battery manufacturers to commercialize its technology for 2024-25 model year EVs.

Enevate utilizes a higher energy density material and an ultra-thin multi-layer design in its large format EV cells that meet EV specifications. This has the potential to lower an EV’s carbon footprint at the start of life, which is significant because battery manufacturing is the highest contributor of emissions for the EV manufacturing.

For example, a 21% greenhouse gas emissions reduction over conventional batteries manufactured in a 100 gigawatt-hour per year lithium-ion EV battery factory would be the equivalent of eliminating driving emissions annually from approximately 511,000 gasoline-powered cars or not burning about 265 million gallons of gasoline each year. 

Philippe Schulz, VP advanced powertrain engineering – Groupe Renault, said:

The CO2 emission reduction Enevate’s battery technology offers is a very desirable contribution to Renault’s aim to reach carbon neutrality in Europe by 2040 and worldwide by 2050. Furthermore, it provides another critical milestone to bring this battery technology to sustainable EV production by 2025.

Hungary bans Irish rap group Kneecap from entering country over ‘antisemitic hate speech’

Hungary bans Irish rap group Kneecap from entering country over 'antisemitic hate speech'

Hungarian authorities have banned the Irish rap group Kneecap from entering the country, accusing them of engaging in “antisemitic hate speech” and “supporting terrorism”. 

Kneecap were set to perform at the Sziget Festival, taking place from 6 to 11 August in Budapest.

The Belfast-based band, which often shares pro-Palestinian messages during its shows, has attracted controversy in recent months after accusing the Israeli government of committing “genocide” in Gaza.

Hungarian government spokesman Zoltan Kovacs said on Thursday that the band’s members “repeatedly engage in antisemitic hate speech supporting terrorism and terrorist groups”.

“Hungary has zero tolerance for antisemitism in any form,” Kovacs said on X, adding that the band’s planned performance “posed a national security threat,” and the band has therefore been formally banned from entering Hungary for three years.

“If they enter, expulsion will follow under international norms,” Kovacs added.

Responding to the spokesman’s comments, Kneecap said “there is no legal basis” for Hungary’s decision and that “no member of Kneecap has ever been convicted of any crime in any country”.

“It is clear that this is a political distraction and a further attempt to silence those who call out genocide against the Palestinian people,” the band said in a statement on X.

During Kneecap’s gig at Britain’s Glastonbury Festival in June, frontman Liam Óg Ó hAnnaidh, performing under the stage name Mo Chara, accused Israel of war crimes in Gaza.

Ahead of the gig, Prime Minister Keir Starmer said he doesn’t think Kneecap’s planned performance was “appropriate”.

Following Kneecap’s performance at Glastonbury, a criminal investigation was launched into comments made on stage by the trio. However, police ultimately decided not to pursue further action, citing “insufficient evidence to provide a realistic prospect of conviction for any offence”.

Kneecap called the investigation “political policing intimidation”.

Mo Chara has been formally charged with a terrorism offence after allegedly displaying a flag in support of the militant group Hezbollah during a gig in November. He denies the offence.

Hezbollah is designated as a terrorist organisation by the UK and the US.

Hulk Hogan dies aged 71

The legendary WWE wrestler Hulk Hogan has died aged 71.

Police have said emergency services responders treated Hogan at his home in Clearwater, Florida, for cardiac arrest at around 10am local time (3pm UK time) today but he died in hospital around an hour and 15 minutes later.

Hogan, whose real name is Terry Bollea, is perhaps the most iconic star in WWE’s five-decade history – known for his distinctive blonde moustache and colourful headbands.

His charisma and theatrics in the ring are credited with helping to transform professional wrestling into a family entertainment sport.

Hogan was the main draw for the first-ever WrestleMania in 1985 and was a fixture for years in its signature event, facing everyone from Andre The Giant and Randy Savage to The Rock and even company chairman Vince McMahon.

He claimed his first WWE world championship by defeating the Iron Sheik in 1984.

Hogan went on to win five more world championships and was inducted into the WWE Hall of Fame in 2005 by Sylvester Stallone.

WWE said in a post this evening: “WWE is saddened to learn WWE Hall of Famer Hulk Hogan has passed away. One of pop culture’s most recognizable figures, Hogan helped WWE achieve global recognition in the 1980s. WWE extends its condolences to Hogan’s family, friends, and fans.”

Hogan’s friend and fellow former professional wrestler, Ric Flair, wrote on X: “I am absolutely shocked to hear about the passing of my close friend @HulkHogan! Hulk has been by my side since we started in the wrestling business.

“An incredible athlete, talent, friend, and father!”

Hogan was also able to transcend his “Hulkamania” fan base to become a celebrity outside the wrestling world, appearing in numerous movies and television shows, including a reality show about his life on VH1, “Hogan Knows Best”.

Hulk Hogan shows support for Trump at Republican National Convention

In 2024, he appeared at the Republican National Convention to endorse the presidential bid of Donald Trump.

Hogan said he made the decision to support the Republican candidate after seeing his combative, fist-pumping reaction to an attempted assassination on the campaign trail.

In a reference to so-called “Hulkamania”, he ripped off his shirt to reveal a Trump tank top and bellowed to a cheering crowd: “Let Trumpamania run wild, brother… Let Trumpamania rule again!”

US Vice President JD Vance has been one of the first to pay tribute to Hogan, writing on X: “Hulk Hogan was a great American icon. One of the first people I ever truly admired as a kid. The last time I saw him we promised we’d get beers together next time we saw each other. The next time will have to be on the other side, my friend! Rest in peace.”

Hogan’s support of Trump did not go down well with all wrestling fans, but he also faced other controversies.

The gossip website Gawker posted a video in 2012 of him having sex with his former best friend’s wife.

Hogan sued on privacy grounds and was awarded a $140m judgement in 2016.

A year earlier he was suspended by the WWE after another secret recording revealed that Hogan had used a racial slur.

He was reinstated in 2018.

The making of a pop culture phenomenon

Born in the US state of Georgia in August 1953, Hogan played bass guitar in local bands before getting involved in the wrestling scene in Florida in the 1970s.

The young wrestler, who later admitted to taking anabolic steroids during his career, gained notoriety as his biceps turned into what he dubbed the “24-inch pythons.”

The “Hulk” moniker came from comparisons to the comic-book hero portrayed on TV at the time.

He would end up paying royalties to Marvel Comics for years.

“Hogan” was the invention of promoter Vince McMahon, the owner of what was then called the World Wrestling Federation (WWF), who wanted Irish representation among his stable of stars.

He was married three times and had two children.

In an update at 1.47pm local time (6.47pm UK time), Clearwater Police Major Nate Burnside said there were “no signs of foul play or suspicious activity” in relation to Hogan’s death.

He added that Hogan’s family are being supported.

Sir Elton John described Osbourne as his “dear friend” and a “huge trailblazer” who “secured his place in the pantheon of rock gods”.

“He was also one of the funniest people I’ve ever met,” the singer wrote on Instagram.

Ronnie Wood, of The Rolling Stones, wrote: “I am so very sad to hear of the death of Ozzy Osbourne. What a lovely goodbye concert he had at Back To The Beginning in Birmingham.”

Born John Michael Osbourne on 3 December 1948 in Aston, Birmingham, he became known as the godfather of heavy metal.
