Knot theory could help spacecraft navigate crowded solar systems

Space modules must be able to switch orbits in order to explore a solar system Elen / Alamy Stock Photo When a spacecraft is circling a planet or sailing among a set of moons, navigating between different orbits can be tough – but a trick from knot theory may help. It can be used to identify points called heteroclinic connections, where a craft can transfer from one orbit to another without burning any of its precious fuel. “These heteroclinic connections, a lot of the time we know there are some for a pair of orbits, but… Source link

NATO has air defense systems ready for Ukraine, Stoltenberg says – POLITICO

“NATO defense ministers have agreed to step up and provide further military support, including more air defense. NATO has mapped out existing capabilities across the lines and there are systems that can be made available to Ukraine,” Stoltenberg said. “So I expect new announcements on air defense capabilities for Ukraine soon … I expect concrete announcements in the near future based on the information that was shared with us,” he added. While the focus is on the Patriot system, “there are other weapons that allies can provide, including SAMP/Ts,” the NATO boss said, adding: “Many allies who do not have available systems have pledged to provide financial support to purchase them for Ukraine.” NATO is also working with industry to ramp up production and to refurbish systems to make them operational and fit for purpose, he said.

How Israel uses facial recognition systems in Gaza and beyond | Facial recognition

Published by skeptic

Governments around the world have increasingly turned to facial recognition systems in recent years to target suspected criminals and crack down on dissent. The recent boom in artificial intelligence has accelerated the technology’s capabilities and proliferation, much to the concern of human rights groups and privacy advocates who see it as a tool with immense potential for harm. Few countries have experimented with the technology as extensively as Israel, which the New York Times recently reported has developed new facial recognition systems and expanded its surveillance of Palestinians since the start of the Gaza war. Israeli authorities deploy the system at checkpoints in Gaza, scanning the faces of Palestinians passing through and detaining anyone with suspected ties to Hamas. The technology has also falsely tagged civilians as militants, one Israeli officer told the Times. The country’s use of facial recognition is one of the new ways that artificial intelligence is being deployed in conflict, with rights groups warning this marks an escalation in Israel’s already pervasive targeting of Palestinians via technology. In an Amnesty International …

NATO Secretary-General Says Some Allies Have Air Defense Systems They Could Give to Ukraine

NATO Secretary-General Says Some Allies Have Air Defense Systems They Could Give to Ukraine

Published by skeptic

BRUSSELS (AP) — NATO Secretary-General Jens Stoltenberg on Friday pressed member countries to give more Patriot missile systems to Ukraine as President Volodymyr Zelenskyy repeated Kyiv’s almost daily appeals for more Western air defense equipment. “NATO has mapped out existing capabilities across the alliance and there are systems that can be made available to Ukraine,” Stoltenberg told reporters after an online meeting of defense ministers from the 32-nation alliance, which Zelenskyy took part in remotely. Russia’s air force is vastly more powerful than Ukraine’s, but sophisticated missile systems provided by Kyiv’s Western partners are a major threat to Russian aviation as the Kremlin’s forces slowly push forward along the around 1,000-kilometer (620-mile) front line in the war. Kyiv is seeking at least seven Patriot batteries. Stoltenberg declined to say which NATO nations have air defense systems or how many might be available, saying that this is classified information, but he insisted that he expects the countries to make new announcements of support soon, not only Patriots. “Allies must dig deep into their inventories and speed …

Sustainable food systems should be established through new agricultural standards

Sustainable food systems should be established through new agricultural standards

Published by skeptic

Helmholtz Centre for Environmental Research has found that EU agricultural trade policies should be renegotiated globally to establish sustainable food systems. The cultivation of soya, palm oil, coffee, cocoa, sugar, or hazelnuts in their countries of origin outside Europe is sustainable in only a minority of instances. For example, rainforests are cleared, and valuable grasslands are used for palm oil and cocoa plantations. As well as this, harmful pesticides are used in the cultivation of cocoa and hazelnuts. The EU has expressed its share of responsibility for preventing negative consequences for biodiversity and the climate. It is committed to the principle of Policy Coherence for Development. Accordingly, the EU wants to achieve the UN Sustainable Development Goals within the EU and support developing countries in implementing them. In the EU Green Deal and the Farm to Fork Strategy, the EU Commission has committed to promoting the transformation towards sustainable food systems. Now, the research team is proposing a new approach to navigating the complex agricultural trade policies between the EU and exporting countries. The approach …

“If allies face a choice between meeting NATO capability targets and providing more aid to Ukraine, my message is clear: Send more to Ukraine,” he said, adding that Ukrainian President Volodymyr Zelenskyy would attend a NATO-Ukraine Council on Friday. Shortly after Stoltenberg’s press conference, NATO announced he would join the G-7 foreign ministers’ meeting in Italy on Thursday, where they are set to discuss Ukraine and the Middle East. A Russian airstrike killed 13 Ukrainians on Wednesday, an incident that Zelenskyy said could have been avoided if Kyiv had received sufficient Western military aid in advance. POLITICO reported Wednesday that Germany’s Foreign Affairs Minister Annalena Baerbock and Defense Minister Boris Pistorius are launching an “Immediate Action on Air Defence” initiative to persuade partners in NATO and beyond to send urgently needed air defense systems to Ukraine. Dutch Prime Minister Mark Rutte, who is widely expected to succeed Stoltenberg later this year, said during the same press conference that the Netherlands, Denmark and the Czech Republic “will consider … in what ways we can [give] support to …

Israel Used Iron Dome and Arrow 3 Systems to Block Attack

Israel Used Iron Dome and Arrow 3 Systems to Block Attack

Published by Sam

Israeli forces used two main defensive weapons, the Iron Dome and the Arrow 3, to shoot down most of the more than 300 drones, ballistic missiles and cruise missiles fired at its territory by Iran, while others were shot down by the United States and other allies. Here’s a look at the two Israeli systems: Iron Dome Israel’s Iron Dome defense system can intercept many types of rockets that fly in high arcs, making them difficult to stop. It became operational in 2011 and got its first big test over eight days in November 2014, when Gaza militants fired some 1,500 rockets at Israel. While Israeli officials claimed a success rate of up to 90 percent during that conflict, outside experts were skeptical. The system’s interceptors — just 6 inches wide and 10 feet long — rely on miniature sensors and computerized guidance to zero in on short-range rockets. Israel’s larger interceptors — the Patriot and Arrow systems — can fly longer distances to go after bigger threats. The Iron Dome was upgraded in 2021, …

Linux XZ Utils malicious backdoor was a CVE 10 risk to Linux systems

Published by skeptic

If you’re managing or using Linux systems, it’s crucial to understand the recent security threat that has emerged. The XZ Utils, an essential tool for lossless data compression on Linux, was discovered to have a backdoor that posed a significant risk to nearly all Linux systems. This revelation has caused considerable concern within the tech community due to the potential widespread impact. The Common Vulnerabilities and Exposures (CVE) system that provides a reference method for publicly known information-security vulnerabilities and exposures assigned a CVE severity score of 10/10 to the Linux XZ Utils backdoor. The initial detection of the issue was made by Andres Freund a PostgreSQL developer at Microsoft, who observed unexpected SSH login delays and unusual CPU usage spikes on a Debian Linux system. This led to an investigation that revealed the presence of a backdoor in the XZ Utils, originating directly from the official XZ repository. Consequently, any system that had installed the compromised updates was vulnerable, leaving countless Linux servers and workstations exposed to potential attacks.
