High-wind warnings and advisories were posted for a vast region stretching from the Mexico border through Los Angeles to the San Francisco Bay area. The National Weather Service (NWS) issued an excessive- rainfall notice for much of the Southern California coast, warning of an at least a 40% chance of showers exceeding flash-flood conditions. Heavy showers began drenching the Los Angeles region before dawn and triggered some street flooding but tapered off by early afternoon. Up to 3 inches (7.6 centimeters) of rain was expected in coastal regions and valleys of Southern California, and as much as 6 inches in lower mountains and foothills, the NWS said.

Earth's axis — the invisible line around which it spins — is bookended by the north and south poles. But their geographic locations aren't fixed: As the Earth's axis moves, so do the poles. If you average out thousands of years of observation the Earth's axis points in a single direction — toward the North Star, also known as Polaris. The recent change to Earth's axis won't affect our everyday lives, but it could slightly tweak the length of our days. But let's be clear that this would be a tiny, tiny, tiny effect," he said.
Explainer: Everything to know about nuclear fuel uranium
  + stars: | 2023-03-16 | by ( ) www.reuters.com   time to read: +3 min
Here is everything you need to know about uranium and its usage as a nuclear fuel. WHAT IS URANIUM USED FOR? The radioactive metal is the most widely used fuel for nuclear energy due to its abundance and the relative ease of splitting its atoms. It is also used in treating cancer, for naval propulsion, and in nuclear weapons. HOW MUCH URANIUM IS NEEDED FOR A NUCLEAR WEAPONThe amount of uranium that went missing contains enough of the U-235 isotope to build a first-generation nuclear bomb if enriched to over 90%, according to Dr. Edwin Lyman from the Union of Concerned Scientists.
New analysis reveals dynamic volcanism on Venus

A February 1991 image showed the vent as a circular formation covering about one square mile (2.6 square km). A October 1991 image showed the vent with an irregular shape covering about 1.5 square miles (3.9 square km). Another study published in 2020 identified 37 volcanic structures apparently active in the past 2 million to 3 million years. Venus, with a diameter of about 7,500 miles (12,000 km), is slightly smaller than Earth. Its thick atmosphere - mainly carbon dioxide - traps in heat in a runaway greenhouse effect, rendering Venus the solar system's hottest planet.

WASHINGTON, March 14 (Reuters) - Beta Technologies is pursuing Federal Aviation Administration (FAA) certification for a fixed-wing electric airplane after receiving orders from three customers, the company announced Tuesday. The privately-held, Vermont-based startup sees certification of the CX 300 – a conventional takeoff and landing version of its Alia 250 electric vertical takeoff and landing (eVTOL) aircraft - as a path to introduce an electric aircraft into U.S. airspace under existing regulations, Chief Executive Kyle Clark told Reuters. Bristow Group, a helicopter service provider that has previously ordered eVTOL aircraft from Beta, has placed an order for up to 50 CX 300 electric planes, Beta said. As the air transport industry works to lower carbon emissions, electric "air taxis" are seen as a potential gamechanger that would allow airlines and other companies to shuttle people and goods by air over short distances. If successful, Beta can reuse much of the data to certify its eVTOL Alia aircraft, which uses the same airframe, batteries and propulsion system, Clark said.
The agreement will also see U.S. and British submarines deployed in Western Australia to help train Australian crews and bolster deterrence. This first phase of the plan is already underway with the U.S. Virginia-class nuclear-powered attack submarine Asheville visiting Perth in Western Australia, officials said. Briefing a small group of reporters on Friday, Sullivan dismissed China's concerns and pointed to Beijing's own military buildup, including nuclear-powered submarines. 'DOUBLE DIGIT BILLION' INVESTMENTAustralia had agreed to contribute funds to boost U.S. and British submarine production and maintenance capacity, the official said. Australia's nuclear-powered submarine program with the United States and Britain will cost Australia up to A$368 billion ($245 billion) by 2055, a defense official said.
Australia will receive conventionally-armed, nuclear-powered submarines under an agreement announced following a Monday meeting of the leaders of the United States, the United Kingdom and Australia. "The plan we announce today delivers on this commitment and reflects our longstanding leadership in, and respect for, the global nuclear non-proliferation regime." The submarines will be modeled after the United Kingdom's next-generation nuclear submarine design and include up-to-date U.S. technology. Known as "SSN-AUKUS" after the strategic partnership among the countries, they will be built and used by both the U.K. and Australia. Pending congressional approval, the U.S. will seek to sell Australia three Virginia class nuclear-powered submarines beginning in the early 2030s.
China has objected to the transfer of nuclear propulsion technology to Australia. read moreThe 2021 announcement that the U.S. and Britain would share nuclear submarine technology with Australia came as a surprise to many Southeast Asian governments, said Perth USAsia Centre chief executive Gordon Flake. Government modelling showed 20,000 jobs, including 8,500 in submarine construction, would be created in Australia over 30 years, local newspapers reported on Monday. "This is about jobs, including jobs and manufacturing and Adelaide in particular will be a big beneficiary of this announcement, as well as Western Australia," he told reporters on Saturday. Flake said Albanese was correct to focus on the longer-term economic impact of servicing the nuclear submarine fleet.
LONDON, March 11 (Reuters) - British Prime Minister Rishi Sunak is flying to the United States on Sunday to meet U.S. President Joe Biden and Australian Prime Minister Anthony Albanese in order to finalise details of a submarine pact aimed at countering China. Since the last update in 2021, Russia has invaded Ukraine and tensions with China have risen. Sunak praised the AUKUS alliance on Saturday and said such partnerships exemplified Britain's approach. "In turbulent times, the UK's global alliances are our greatest source of strength and security," he said. Under the initial AUKUS deal announced in 2021, the United States and Britain agreed to provide Australia with the technology and capability for nuclear-powered submarines.
Two of the officials said that after the annual port visits, the United States would forward deploy some submarines in Western Australia by around 2027. In the early 2030s, Australia would buy three Virginia class submarines and have the option to buy two more. It will be the first time the United States has shared nuclear-propulsion technology since it did so with Britain in the 1950s. Currently no party to the nuclear Non-Proliferation Treaty other than the five countries the NPT recognizes as weapons states - the United States, Russia, China, Britain and France - has nuclear submarines. General Dynamics Corp (GD.N), which makes Virginia class submarines, has 17 of them in its current backlog delivering through 2032.
Sooner than that, around 2027, U.S. nuclear submarines are expected to be deployed in Western Australia. It is vital that Australia has the same capability to deter - or, if necessary, fight - China as it expands its nuclear submarine fleet and ranges deeper into Australia's northern waters, he said. A U.S. Defense Department report last year said the People's Liberation Army Navy (PLAN) had a fighting force of 340 ships and submarines, including 12 nuclear submarines - six equipped with ballistic missiles - and 44 conventionally powered submarines. The report added that China would build a guided missile submarine by the middle of this decade. The U.S. has long wanted to base its nuclear submarines in Australia, and if that is the near-term solution under AUKUS, it is a significant shift, Gill said.
South Korea's defense industry has seen meteoric growth in recent years. 2023 is also shaping up to be a good year for South Korea's defense industry. South Korea's defense industry was originally tailored to meet the country's own needs, and Seoul assisted its growth with subsidies and other incentives. As South Korea's defense products increased in quality, so too did its exports. The South Korean defense industry's most anticipated product might be the KF-21 Boramae, a multi-role combat jet optimized for air-superiority missions.

Sakchai Lalit/Pool via REUTERS/File PhotoSYDNEY/WASHINGTON, March 8 (Reuters) - Australian Prime Minister Anthony Albanese said on Wednesday he will visit the United States to meet President Joe Biden after a trip to India this week. "I look forward to the continuing engagement that I have with the U.S. administration," Albanese told reporters before leaving for India, without giving a date for his U.S. trip. Ashley Townshend, an Australian Defense expert at the Carnegie Endowment for International Peace think tank, said a new information-sharing agreement would be needed for the submarine program's implementation stage. Albanese will reach India later on Wednesday and will stay until Saturday in the first visit by an Australian prime minister since 2017.
Boeing's lineup of unmanned, undersea vehicles (UUV) can operate autonomously for months at a time on a hybrid rechargeable propulsion power system. More than 80% of the ocean remains unexplored by humans but could soon be mapped by autonomous underwater robots. Autonomous robot submarines — also referred to as autonomous underwater vehicles, or AUVs — are able to explore high-pressure areas of the ocean floor that are unreachable by humans through preprogrammed missions, allowing them to function without humans aboard, or controlling them. Navies worldwide are investing in unmanned underwater vehicles to elevate their fleet of below-water defense tools. The U.K.'s Ministry of Defence also announced in August the donation of six autonomous underwater drones to Ukraine to aid in their fight against Russia by locating and identifying Russian mines.
NEW DELHI/BERLIN, Feb 24 (Reuters) - Germany will pursue a $5.2 billion deal with India to jointly build six conventional submarines in the country during Chancellor Olaf Scholz’s Feb. 25-26 visit, two Indian and two German sources said. Under the deal, a foreign submarine manufacturer will have to partner with an Indian company to build the submarines in India. The Indian foreign and defence ministries did not respond to requests for comment. An Indian diplomatic source told Reuters that India has asked Germany for an assurance for joint manufacturing for the submarines, not just supply-side support. Another official from the Indian foreign ministry said that “Scholz was determined to reinvigorate trade and defence ties with India”.
Lordstown Motors Recalls Endurance EV Pickup Truck
  + stars: | 2023-02-23 | by ( Will Feuer | ) www.wsj.com   time to read: 1 min
An unfinished Endurance pickup on an electric-vehicle assembly line in Lordstown, Ohio. Electric-vehicle startup Lordstown Motors Corp. issued a recall and halted production of its Endurance pickup truck, only months after starting to make the vehicle. Lordstown Motors said Thursday that the recall affects 19 vehicles that are either held by customers or being used internally at the company. The company said it issued the voluntary recall to address an electrical-connection issue that could lead to a loss of propulsion while driving.
Lordstown Motors gave rides in prototypes of its upcoming electric Endurance pickup truck on June 21, 2021 as part of its "Lordstown Week" event. Lordstown Motors said Thursday it will suspend production and deliveries of its all-electric Endurance pickup to address performance and quality issues with certain components. Lordstown said it is working with suppliers to implement a solution that the company believes will address the issue. The company declined to forecast how long production will be idled at the Ohio plant, which Lordstown purchased from General Motors in 2019. The recall and production problems add to a long list of issues at Lordstown since the company went public nearly 2½ years ago.

KYIV, Feb 15 (Reuters) - Six Russian balloons were spotted over Kyiv and most were shot down after being engaged by air defences, the Ukrainian capital's military administration said on Wednesday. It said the balloons may have been carrying corner reflectors and reconnaissance equipment but did not specify when they flew over the capital, although air alerts were issued in Kyiv on Wednesday. "Reconnaissance drones like the Orlan-10 are now being used more sparingly (by Russia), and they thought 'Why don't we use these balloons?' He later confirmed that air raid sirens had blared in the capital on Wednesday because of balloons flying overhead. Russia did not immediately comment on the reports of balloons over Kyiv.
Electric cars require different service and maintenance than gas-powered ones. They also wonder what it means to service and maintain these vehicles — and how much that will cost them. Tesla even advertises its vehicles as "eliminating the need for service." EV tires are different than those for a gas-powered vehicle. What it means for car dealersAs a result of these shifts, dealers are assessing just how much of an impact that potentially less vehicle service will have on their bottom lines.
WASHINGTON, Feb 12 (Reuters) - The U.S. Air Force general overseeing North American airspace said on Sunday after a series of shoot-downs of unidentified objects that he would not rule out aliens or any other explanation yet, deferring to U.S. intelligence experts. It was the third unidentified flying object to be knocked out of the sky by U.S. warplanes since Friday, following the Feb. 4 downing of a suspected Chinese weather balloon that put North American air defenses on high alert. "We're calling them objects, not balloons, for a reason, said VanHerck, who is head of the joint U.S.-Canadian North American Aerospace Defense Command (NORAD) and the U.S. Air Force Northern Command. However, the government's effort to investigate anomalous, unidentified objects — whether they are in space, the skies or even underwater — has led to hundreds of reports that are being investigated, senior military leaders have said. But so far, the Pentagon has not found evidence to indicate Earthly visits from intelligent alien life, those officials have said.
