And splashdown! America is back in the business of sending astronauts to the Moon and bringing them home safely. Reid, Victor, Christina, and Jeremy did an outstanding job. These talented astronauts inspired the world and represented their space agencies and nations as humanity’s ambassadors to the stars. This was a test mission, the first crewed flight of SLS and Orion, pushing farther into the unforgiving environment of space than ever before, and it carried real risk. They accepted that risk for all we stood to learn and for the exciting missions that follow, as we return to the lunar surface, build a Moon base, and prepare for what comes next. And they were not alone. The entire NASA workforce, our commercial and international partners, and the hopes and dreams of people all over the world were with them. The astronauts know it, and you should too. This mission would not have been possible without you. Congratulations. Artemis II, mission accomplished.

The Moon fundamentally changes the game for manned space exploration. It is a next-level proving ground where astronauts can build habitats, harvest propellant and minerals from the lunar surface, and learn the skills necessary to go onto Mars.

"It's one thing to land on the moon; it's a whole other thing to colonize it." @MikeHaridopolos joins @jsolomonReports and @AmandaHead to highlight the upcoming @NASA Artemis III mission, its historical significance, and the goal of establishing a sustainable human presence on the moon by 2028.

“We’re fulfilling a promise that began more than 35 years ago.” NASA’s Artemis II mission is not only a “stepping stone” to Mars, says NASA Administrator Jared Isaacman, but could also inspire a new generation. “How many kids after this mission are going to dress up as astronauts for Halloween and want to grow up and contribute to this great adventure?”

NASA Administrator Jared Isaacman says the primary objective of the Artemis II’s trip around the moon is “to gather data from the ECLSS system, the life support system on the Orion spacecraft,” which will be used in future missions. “Learning as much as we can about Orion is critically important because Artemis III is a year away,” he says. “That's where we're going to test the same spacecraft with our lunar landers. Followed up in 2028 by Artemis IV, where we're going to use this spacecraft, transfer crew to the landers, and put American astronauts back on the surface of the moon.”

😁 At Orbán’s campaign rally, the crowd chants “Russians, go home” “Ruszkik haza” (“Russians, go home”) is a slogan that emerged during the Hungarian Revolution of 1956 and was directed against Soviet troops. Seems like the campaign isn’t going quite as planned.

Volodymyr Zelenskyy / Володимир Зеленський
Providing Ukraine with a loan using frozen Russian assets was the agreed position of all EU leaders at the end of 2025. The alternative to this step is now up to the European Union. We will be grateful if they can unblock this format. If they do not, we hope for an alternative that would allow us to access these funds. Otherwise, the Ukrainian army will be underfunded. Drone production – of long-range drones and interceptors – will also be underfunded, as will air defense systems, because we allocate part of those funds to European air defense systems and to the U.S. PAC-3 missiles. This is a risk for everyone. It is a risk to European security. I believe there will be no collapse, and the Europeans will resolve this issue. From an interview with Le Monde (5/5).

The premise l👇leads to an uncomfortable but necessary conclusion: European “strategic autonomy” cannot mean autonomy from the United States. It must mean autonomy from Russia. Those who argue for distancing Europe from Washington are, whether they admit it or not, accepting a much more dangerous alternative: structural dependence on Moscow at least for half of the continent. Security vacuums in Europe are never neutral; they are always filled. The post WW2 record is instructive. Under the American security umbrella, Western Europe could afford to debate, trade, and even disagree, while remaining fundamentally secure. The beaches of France, Italy, Spain, and Portugal were places of leisure precisely because hard security was guaranteed elsewhere. The real question, then, is not whether Europe should be more capable. It should. But capable for what and independent from whom? Autonomy that weakens the transatlantic bond does not produce sovereignty. It produces exposure.
Ulrich Speck@ulrichspeck

The key fact about European security is that neither the UK, nor France, nor Germany would risk a war with Russia without the US going first and leading. That hasn't changed.

Russian writer and critic of Putin, Dmitry Glukhovsky explains that generations of Russians have been so easily brainwashed because mainstream propaganda in Russia is like beetroot soup. Even if you are not the beetroot, you still become red merely from being in the same environment. The Kremlin’s system is built on manufacturing a sense of normality, built from extreme narratives that are parroted by “Sologubovs” - otherwise normal, educated, respectable voices, presenters, cultural figures, and intellectuals who do not shout propaganda, but normalize the system around them. This is how information manipulation works in Russia today. Not by convincing everyone, but by shifting what feels normal, acceptable, and inevitable. When war becomes “politics,” aggression becomes “security,” and crimes become “complicated history,” propaganda has done its job. This is why information space matters. Because the most dangerous propaganda is not the one that makes you believe. It is the one that makes you accept.

For every dollar Denmark spends on Ukraine, France sends 7 cents, Italy 7 cents, the US zero. Denmark has given 3.25% of GDP—the highest in the world. On election day, Ukraine barely comes up. Not because Danes don't care—70% agree on keeping the support going. A reporter walked Aarhus asking voters. Out of 40–50 people, one disagreed. His wife interrupted him. If all NATO countries had matched Denmark, Ukraine would have received $2 trillion—not $350 billion. euromaidanpress.com/2026/03/24/den…

Loistava aloitus eduskuntavaaleihin 2027! Uudenmaan Kokoomus järjesti jäsenäänestyksen suosikkiehdokkaistaan. Pääsin sijalle 9/60, nykyisten kansanedustajien väliin. Viime kerralla Uudeltamaalta valittiin 11 edustajaa kokoomuksesta eli mikäli jäsenistö saisi päättää, olisin eduskunnassa! Tietenkin oikeat vaalit ovat paljon monimutkikkaammat ja jännittää, mitä tuleva vuosi tuo tullessaan. Siksi olen avoin kaikelle mahdolliselle avulle ja tuelle! Kertokaa ihmeessä, jos mielitte matkalleni mukaan tai on muita ajatuksia.

@bingatupamaki Hienoa että olet jaksanut selittää tätä asiaa ! Perintöveron muutos luovutusvoittoveroksi lisää kotimaisen pääoman kertymistä kun vältytään pakkomyynneiltä - kasvuyrityksille enemmän rahoitusmahdollisuuksia. Ruotsissa tämä toimii.

Täällä ollaan kilpaa väittelemässä siitä, miten luovutusvoittovero ei toimisi perintöveron sijasta. Väännetään hankintahinnasta ja laskutavasta. Ruotsissa se toimii erinomaisen hyvin. Mikäköhän siinä on? Siellä on varmaan niin paljon älykkäämpää porukkaa?

@visegrad24 Ukrain has agreed on a ceasefire and russia has not, which was to be expected from the aggressor. More help for Ukrain and more sanctions against Russia are needed.
