NASA’s DART spacecraft successfully slammed into a distant asteroid at hypersonic speed on Monday in the world’s first test of a planetary defense system, designed to prevent a potential doomsday meteorite collision with Earth. From a report: Humanity’s first attempt to alter the motion of an asteroid or any celestial body played out in a NASA webcast from the mission operations center outside Washington, D.C., 10 months after DART was launched. The livestream showed images taken by DART’s camera as the cube-shaped “impactor” vehicle, no bigger than a vending machine with two rectangular solar arrays, streaked into the asteroid Dimorphos, about the size of a football stadium, at 7:14 p.m. EDT (2314 GMT) some 6.8 million miles (11 million km) from Earth. The $330 million mission, some seven years in development, was devised to determine if a spacecraft is capable of changing the trajectory of an asteroid through sheer kinetic force, nudging it off course just enough to keep Earth out of harm’s way. Whether the experiment succeeded beyond accomplishing its intended impact will not be known until further ground-based telescope observations of the asteroid next month. But NASA officials hailed the immediate outcome of Monday’s test, saying the spacecraft achieved its purpose.

Noam Izenberg, a researcher at the Johns Hopkins University’s applied physics laboratory, is making a case for sending a crewed mission to examine Venus en route to Mars. “Venus gets a bad rap because it’s got such a difficult surface environment,” said Izenberg in a report presented at the International Astronautical Congress in Paris last week. “The current Nasa paradigm is moon-to-Mars. We’re trying to make the case for Venus as an additional target on that pathway.” The Guardian reports: There are notable downsides. Walking on the surface would be an unsurvivable experience, so astronauts would have to gaze down at the planet from the safety of their spacecraft in a flyby mission. In its favor, however, Venus is significantly closer, making a return mission doable in a year, compared with a potentially three-year roundtrip to Mars. A flyby would be scientifically valuable and could provide crucial experience of a lengthy deep-space mission as a precursor to visiting Mars, according to a report presented at the International Astronautical Congress (IAC) in Paris last week.

Izenberg said there were practical arguments for incorporating a Venus flyby into the crewed Mars landing that Nasa hopes to achieve by the late 2030s. Although the planet is in the “wrong” direction, performing a slingshot around Venus — known as a gravity assist – could reduce the travel time and the fuel required to get to the red planet. That would make a crewed flyby trip to Venus a natural stepping stone towards Nasa’s ultimate goal. “You’d be learning about how people work in deep space, without committing yourself to a full Mars mission,” he said. “And it’s not just going out into the middle of nowhere — it would have a bit of cachet as you’d be visiting another planet for the first time.” “We need to understand how we can get out of the cradle and move into the universe,” he added.

There is also renewed scientific interest in Venus. The discovery of thousands of exoplanets raises the question of how many might be habitable, and scientists want to understand how and why Venus, a planet so similar to our own in size, mass and distance from the sun, ended up with infernal surface conditions. Izenberg said a Venus flyby “doesn’t yet have traction” in the broader space travel community, although there are advocates within Nasa, including its chief economist, Alexander Macdonald, who led the IAC session. Of course, there are those who push back against such an idea. “It’s really not a nice place to go. It’s a hellish environment and the thermal challenges for a human mission would be quite considerable,” said Prof Andrew Coates, a space scientist at UCL’s Mullard space science laboratory.

He said Venus was rightly a focus of scientific exploration, but that “a human flyby really wouldn’t add very much.”

An anonymous reader quotes a report from the Hill: Passenger rail service Amtrak is aiming to achieve net-zero greenhouse gas emissions by 2045 to reduce its impact on the environment. Amtrak on Thursday announced efforts to hit that mark will involve reducing the use of diesel fuel and phasing in renewable fuels in its network over the next decades. The rail service said it plans to reach 100 percent carbon-free electricity by 2030 by investing in new fuel-cell, hydrogen and battery technologies.

Funds from President Biden’s bipartisan infrastructure law will be used to help Amtrak develop a more sustainable fleet, expand service and revamp part of the rail’s aging infrastructure. The legislation includes $66 billion in rail funding, the largest federal investment in passenger rail since the creation of Amtrak. Amtrak executives said setting clear goals to reduce emissions is particularly important for attracting “a new generation of travelers who are conscious of their environmental impact.”

Amtrak last year announced a $7.3 billion investment to procure 83 new trains that will operate mostly along the Northeast Corridor, which include some of the first hybrid-electric powered trains. The trains will start replacing older trains, some of which are nearly 50 years old, in 2024. The transportation sector generates the largest share of greenhouse gas emissions in the U.S., making up 27 percent of total emissions in 2020. Rail makes up just 2 percent of transportation emissions, while cars and trucks make up more than 80 percent.

U.S. lawmakers and TikTok are hammering out a plan, under which the short-form video app would make changes to its data security and governance without requiring its parent firm, China’s ByteDance to sell it, the New York Times reported on Monday. Reuters reports: TikTok and the Biden administration have drafted a preliminary agreement to resolve national security concerns but are still deciding on a potential agreement, the Times reported, citing people familiar with the matter. A TikTok spokesperson declined to comment on the report but said the app was confident about being able to “fully satisfy all reasonable U.S. national security concerns.” TikTok’s parent company ByteDance was ordered to divest the company more than two years ago over fears that U.S. user data could be passed on to China’s communist government.

An anonymous reader quotes a report from the New York Times: Ever since American manufacturing entered a long stretch of automation and outsourcing in the late 1970s, every recession has led to the loss of factory jobs that never returned. But the recovery from the pandemic recession has been different: American manufacturers have now added enough jobs to regain all that they shed — and then some. The resurgence has not been driven by companies bringing back factory jobs that had moved overseas, nor by the brawny industrial sectors and regions often evoked by President Biden, former President Donald J. Trump and other champions of manufacturing. Instead, the engines in this recovery include pharmaceutical plants, craft breweries and ice-cream makers. The newly created jobs are more likely to be located in the Mountain West and the Southeast than in the classic industrial strongholds of the Great Lakes.

American manufacturers cut roughly 1.36 million jobs from February to April of 2020, as Covid-19 shut down much of the economy. As of August this year, manufacturers had added back about 1.43 million jobs, a net gain of 67,000 workers above pre pandemic levels. Data suggest that the rebound is largely a product of the unique circumstances of the pandemic recession and recovery. Covid-19 crimped global supply chains, making domestic manufacturing more attractive to some companies. Federal stimulus spending helped to power a shift in Americans’ buying habits away from services like travel and restaurants and toward goods like cars and sofas, helping domestic factory production — and with it, job growth — to bounce back much faster than it did in the previous two recessions.

In recessions over the last half century, factories have typically laid off a greater share of workers than other employers in the economy, and they have been slower to add jobs back in recoveries. Often, companies have used those economic inflection points to accelerate their pace of outsourcing jobs to foreign countries, where wages are significantly lower, and to invest in technology that replaces human workers. […] This time was different. Factory layoffs roughly matched those in the services sector in the depth of the pandemic recession. Economists attribute that break in the trend to many U.S. manufacturers being deemed “essential” during pandemic lockdowns, and the ensuing surge in demand for their products by Americans. Manufacturing jobs quickly rebounded in the spring of 2020, then began to climb at a much faster pace than has been typical for factory job creation in recent decades. Since June 2020, under both Mr. Trump and Mr. Biden, factories have added more than 30,000 jobs a month.
“Sectors that hemorrhaged employment in recent recessions have fared much better in this recovery,” reports the NYT. They include furniture makers, textile mills, paper products companies and computer equipment makers.

“Mr. Biden has pushed a variety of legislative initiatives to boost domestic manufacturing, including direct spending on infrastructure, tax credits and other subsidies for companies like battery makers and semiconductor factories, and new federal procurement requirements that benefit manufacturers located in the United States,” adds the report — all of which could help encourage factory job growth in the coming months and years.

Furthermore, the rising tensions between Washington and Beijing over trade and technology could encourage more companies to leave China for the United States, particularly cutting-edge industries like clean energy and advanced computing.

Apple said Monday it is assembling its flagship iPhone 14 in India as the U.S. technology giant looks to shift some production away from China. CNBC reports: “The new iPhone 14 lineup introduces groundbreaking new technologies and important safety capabilities. We’re excited to be manufacturing iPhone 14 in India,” the company said in a statement. Apple’s main iPhone assembler, Foxconn, is manufacturing the devices at its Sriperumbudur factory on the outskirts of Chennai.

The Cupertino, California, giant has been manufacturing iPhones in India since 2017 but these were usually older models. This time with the iPhone 14, Apple is producing its latest model in India for the first time, close to the device’s launch. Apple introduced the iPhone 14 earlier this month. Apple will sell India-produced phones locally but also export them to other markets globally. Customers in India will begin receiving the locally manufactured devices in the next few days. Earlier this month, JPMorgan analysts said that Apple will move 5% of its global production for the iPhone 14 to India by late 2022. The company could also make 25% of all iPhones by 2025 in India.
