KYIV Russia launched about 15 cruise missiles at Ukraines capital on Tuesday, the second attack in as many days, with air defence systems shooting all of them down, officials said, after air raid alerts blared over most of the country.
As at the front, the plans of the aggressor failed, Mr Serhiy Popko, head of Kyivs city military administration, said in comments posted on the Telegram messaging app.
Tuesdays attacks the fifth in May came a day after Russia launched its biggest drone swarm yet in a renewed air campaign unleashed 10 days ago after a lull since early March.
It also came on Russias Victory Day, one of its most commemorated public holidays, marking the anniversary of the defeat of Nazi Germany in 1945.
(They) try to kill as many civilians as possible on this day, said Mr Popko.
He added that according to preliminary information, there were no casualties in the attack that was carried out with cruise missiles from the Caspian Sea region.
Falling debris fell on a house in the Holosiivskyi district in the south-west of the capital, Kyiv mayor Vitalii Klitschko said on his Telegram messaging channel, adding that there were no casualties or much damage.
In the often-targeted Shevchenkivskyi district of central Kyiv, debris was found on a road.
Kyiv stood up again and will stand up in the future, Mr Popko said. REUTERS More On This Topic Russia rains missiles across Ukraine ahead of May 9 Victory Day holiday Russia keeps up missile attacks on Ukraine ahead of expected Kyiv offensive
NASA’s Juno spacecraft, in orbit around Jupiter, had a huge problem when its JunoCam imager started to fail after sitting through the planet’s harsh radiation belts for so many orbits. Designed to only last through the initial few orbits, JunoCam astonishingly endured 34 orbits. Yet by the 47th orbit, the effects of radiation damage became visible, and by the 56th orbit, images were almost illegible. With few alternatives and time slipping away before a close flyby of Jupiter’s volcanic moon Io, engineers made a daring but creative gamble. Employing an annealing process, they sought to resuscitate the imager by warming it up—an experiment that proved successful.
Long-distance fix
According to NASA, JunoCam’s camera resides outside the spacecraft’s radiation-shielded interior and is extremely vulnerable. After several orbits, it started developing damage thought to be caused by a failing voltage regulator. From a distance of hundreds of millions of miles, the mission team implemented a last-ditch repair: annealing. The technique, which subjects materials to heat in order to heal microscopic defects, is poorly understood but has been succeeding in the lab. By heating the camera to 77°F, scientists wished to reorient its silicon-based parts.
At first, efforts were for naught, but only days before the December 2023 flyby of Io, the camera unexpectedly recovered—restoring close-to-original image quality just in time to photograph previously unseen volcanic landscapes.
Radiation Lessons for the Future
Though the camera showed renewed degradation during Juno’s 74th orbit, the successful restoration has led to broader applications. The team has since applied similar annealing strategies to other Juno instruments, helping them withstand harsh conditions longer. Juno’s findings are now informing spacecraft design across the board. “We’re learning how to build radiation-tolerant systems that benefit both defense and commercial satellites,” said Juno’s principal investigator Scott Bolton. These findings would inform future missions, such as those visiting outer planets or working in high-radiation environments near Earth, in the Van Allen belts. Juno’s mission continues to pay dividends with unexpected innovations—a lesson in how a small amount of heat can do wonders.
Israel has resumed airdrops of aid into Gaza, as reports and condemnation of starvation and famine continue to spread.
In a statement, the Israel Defence Forces added that humanitarian corridors would also be established for United Nations convoys to deliver aid into the region, though it did not say when or where.
While the IDF “emphasises that combat operations have not ceased” – and reiterated claims there is “no starvation” in Gaza – it said: “The airdrops will include seven pallets of aid containing flour, sugar and canned food to be provided by international organisations.”

People in Gaza jump on food trucks
The military added that it is prepared to implement “humanitarian pauses” in densely populated areas.
Reports suggest aid has already been dropped into Gaza, with some injured after fighting broke out.
He told Sky News: “This month, up to now, 1,000 children or 1,000 people have died of starvation. I’m really not interested in what either of these sides are saying.”

On Saturday, reports referencing US government data said that there was no evidence Hamashad stolen aid from UN agencies.
The IDF’s international spokesperson, Lieutenant Colonel Nadav Shoshani, described such reports as “fake news” and said Hamas thefts have been “well documented”.

Malnourished girl: ‘The war changed me’
Airdrops ‘expensive and inefficient’
It comes as the Hamas-run health ministry in Gaza said that, as of Saturday, 127 people have died from malnutrition-related causes, including 85 children.
They include a five-month-old girl who weighed less than when she was born, with a doctor at Nasser Hospital describing it as a case of “severe, severe starvation”.
Health workers have also been weakened by hunger, with some putting themselves on IV drips so they can keep treating badly malnourished patients.

Aid waiting to be distributed in Gaza
On Friday, Israel said it would allow foreign countries to airdrop aid into Gaza – but the UN Relief and Works Agency has warned this will not reverse “deepening starvation”.
UNRWA head Philippe Lazzarini described the method as “expensive” and “inefficient”, adding: “It is a distraction and screensmoke. A manmade hunger can only be addressed by political will.
“Lift the siege, open the gates and guarantee safe movements and dignified access to people in need.”
He added that UNRWA has the equivalent of 6,000 trucks in Jordan and Egypt waiting for permission to enter Gaza.

PM says UK will help drop aid to Gaza
MSF, also known as Doctors Without Borders, warned on Friday that 25% of young children and pregnant women in Gaza are now malnourished, and said the lack of food and water on the ground was “unconscionable”.
The UN also estimates that Israeli forces have killed more than 1,000 people seeking food – the majority near the militarised distribution sites of the US-backed aid distribution scheme run by the Gaza Humanitarian Foundation.
In a statement on Friday, the IDF had said it “categorically rejects the claims of intentional harm to civilians”, and reports of incidents at aid distribution sites were “under examination”.
The GHF has also previously disputed that these deaths were connected with its organisation’s operations, with director Johnnie Moore telling Sky News: “We just want to feed Gazans. That’s the only thing that we want to do.”
It begs the question: what other home solar battery solutions are there?
UPDATE 26JUL2025: added more options, put everything in alphabetical order.
Electricians and contractors often praise the sleek, energy-dense Tesla Powerwall, for good reasons. But the Powerwall isn’t the only top-shelf home battery on the market, but long wait times, Elon’s antics, and the proliferation of really good integrated alternatives from legacy EV brands might have you shopping for Tesla alternatives already. If that’s you, the next logical step is to re-think the brand’s solar battery offerings as well – here are some of the best options out there.
If you’re in a smaller space or renting and can’t (or don’t want to) add a hardwired battery solution to your home, Bluetti’s EP800 + B500 modular system is a sweet “middle ground” option that combines the Bluetti EP800 off-grid inverter and the company’s B500 battery packs in a floor-standing unit that can be used without a solar roof but also plays well with most rooftop PV options.
What’s more, it works great with Bluetti’s AC300 or AC500 gear if you want an option that’s a bit more portable if you move a lot or plan on moving soon.

“The EG4 PowerPro solar battery from EG4 Electronics is the strongest alternative to the Tesla Powerwall,” writes Kristina Zagame, from the home solar experts at EnergySage. “(The EG4) has a similar capacity, meaning it’ll last a similar amount of time, and a slightly lower power output, which means it won’t be able to power quite as many devices at the same time. And, based on quotes through EnergySage, EG4 batteries tend to be a bit more affordable compared to Tesla.”
“Energy systems developer Enphase Energy is providing an even more holistic approach to managing home power usage with the introduction of new EV charger technology called the IQ line,” wrote Scooter doll, when the brand first introduced its EV charging solutions back in 2023. “The Enphase IQ is Wi-Fi enabled and integrates seamlessly into a customer’s existing home system that can be controlled with your phone.”
Franklin WH aPower 2

If you love the sleek, minimalistic styling of the Tesla Powerwall 3 but still prefer to spend your money elsewhere, the Franklin WH aPower 2 offers similarly sleek stylingand beats the Tesla offering on usable energy storage capacity by 1.5 kWh. That’s nearly a full day of keeping a modern refrigerator running.
The Franklin is also designed to be easily retrofit into an existing solar system, but it loses out to the Powerwall on price per kWh, at $1,176 (vs. $926 for the Tesla unit).
GM Energy Home System

Arguably the most fully integrated EV + battery backup + solar option out there outside of Tesla, the GM Energy Home System promises to do everything a conventional home solar battery does, plus work seamlessly with your GM EV to provide even more flexibility – whether that means using the electric fuel stored in your EV to hold out that much longer in an emergency, or using the energy stored in your home’s solar battery to power an escape in your EV is up to you.
First, they’re not yet available to the general public – only to StorEn’s early investors in (what I understand to be) a sort of quasi-Kickstarter deal.
Second, the StorEn batteries are significantly bulkier than a Powerwall. That said, if you’ve got the room and you’re old enough to realize that 25 years isn’t actually a super long time, the StorEn solution might to be a super compelling, nearly maintenance-free setup that might outlast both your solar panels and the roof they’re mounted on.
VillaGrid+ battery; via Villara.
So, remember how I started this off saying that I wouldn’t turn this into a “best batteries” post? That’s partly driven by the fact that I’m neither an electrician, a chemical engineer, or someone who’s researched thousands of end-user experience surveys to come up with whatever metrics I’d need to confidently and correctly call one battery “the best.”
Our friends and solar industry experts at EnergySage, though? They’ve got all three of those things on staff, and they really, really like the Villara VillaGrid+.
“The Villara VillaGrid+ stands out as the best battery on the market, scoring highest in EnergySage’s rigorous Equipment Rating System, explains EnergySage’s Kristina Zagame. “That said, (the Villara VillaGrid+) is not necessarily the best Tesla Powerwall alternative. It’s a very different (and much pricier) battery.”
What puts the VillaGrid+ on top? According to Zagame, it all comes down to the battery’s lithium-titanium-oxide, or LTO chemistry. “Unlike more traditional lithium-ion batteries, LTO has better recharge capabilities for longer life cycles, and doesn’t contain any carbon, which makes it extra safe. The only downside is you’ll definitely shell out more money upfront for the VillaGrid+.”
That extra money will also buy some additional peace of mind, as Villara backs its LTO batteries with a 20-year warranty compared to Tesla Powerwall and its (and just about everyone else’s) 10-year deal. I couldn’t find a price, but Villara’s other products, like VillaGrid 5.75 kWh battery, come in at nearly double Powerwall’s per kWh cost. Check out the specs, below, then let us know if you think the novel chemistry and additional warranty are worth it in the comments.
