New pictures from the Ingenuity helicopter offer a fresh perspective of the wreckage left behind when the Perseverance rover landed on Mars last year, NASA said on Wednesday. The Verge reports: Launched in 2020, the Perseverance rover successfully landed on the Red Planet in 2021, with the mission of finding ancient signs of life on Mars. The rover carried the Ingenuity helicopter onboard — an experimental project that scientists on Earth hoped would be able to see sights that the rover couldn’t. Perseverance went through a grueling process known as the seven minutes of terror to descend onto the Martian surface. As it entered the atmosphere, a heat shield helped protect the rover from the blistering heat of reentry and slowed it down dramatically. After that, the massive parachute deployed out of the backshell (a cone-shaped part of the descent vehicle), slowing it down even more. At that point, the backshell and parachute separated from Perseverance and let the descent stage take over, using rocket thrusters and a “sky crane” to gently lower the rover to a smooth landing.

On April 19th, Ingenuity took photographs that captured the remains of Perseverance’s parachute and the rover’s protective backshell, a cone-shaped part of the descent vehicle that carried the parachute and helped protect the rover on its way to the surface. Strewn around the site were debris from where the two crashed into the surface after separating from the rover. The backshell ended up hitting the ground at about 78 miles per hour, according to NASA. From the pictures, it appears that the parachute, the lines connecting the parachute to the spacecraft, and the coating on the outside of the backshell all survived the trip to the surface, NASA says, though more analysis of the pictures will happen in the coming weeks.

An anonymous reader quotes a report from Ars Technica: The US Postal Service is facing lawsuits from 16 states and several environmental groups challenging its decision to buy tens of thousands of gasoline-powered delivery vehicles instead of electric vehicles. As previously reported, the Environmental Protection Agency says the gas-powered trucks being ordered by the USPS “are expected to achieve only 8.6 miles per gallon (mpg), barely improving over the decades-old long-life vehicles that achieve 8.2 mpg.” The USPS countered that the vehicles get 14.7 mpg when air conditioning isn’t being used and that the trucks’ size will make it possible to deliver the same amount of mail in fewer trips. The USPS plan is to buy 50,000 to 165,000 vehicles over 10 years. Of those, at least 10 percent are slated to be battery-electric vehicles (BEV). […]

A lawsuit filed by California and 15 other states on Thursday said the USPS failed “to follow a process mandated by the National Environmental Policy Act (NEPA),” continuing: “Instead, the Postal Service first chose a manufacturer with minimal experience in producing electric vehicles, signed a contract, and made a substantial down payment for new vehicles. Only then did the Postal Service publish a cursory environmental review to justify the decision to replace 90 percent of its delivery fleet with fossil-fuel-powered, internal combustion engine vehicles, despite other available, environmentally preferable alternatives. In doing so, the Postal Service failed to comply with even the most basic requirements of NEPA.”

The lawsuit seeks an injunction forcing the USPS to stop the vehicle purchases “until it has complied with NEPA.” It was filed against the USPS and Postmaster General Louis DeJoy, who was appointed by the USPS Board of Governors in 2020 under then-President Donald Trump. All 16 states involved in the lawsuit have Democratic attorneys general. They allege that the USPS “violated well-established legal precedent prohibiting ‘an irreversible and irretrievable commitment of resources’ before completing the NEPA process by signing contracts with a defense company (Oshkosh Defense, LLC) to procure vehicles six months before even releasing its draft environmental review and a year prior to issuing the Final Environmental Impact Statement (‘Final EIS’) and Record of Decision.” The states also claim the USPS failed to consider and evaluate reasonable alternatives. “Specifically, the Postal Service did not properly evaluate several environmental impacts of its action, including air quality, environmental justice, and climate harms, by simply assuming that any upgrade to its vehicle fleet would have positive impacts on the environment,” the complaint said. States also alleged the USPS “failed to ensure the scientific integrity of its analysis by relying on unfounded assumptions regarding the costs and performance of electric vehicles, infrastructure, and gas prices, and refusing to identify the source of the data relied upon in the Final EIS.” “The Postal Service conducted a robust and thorough review and fully complied with all of our obligations under NEPA,” a USPS spokesperson told Ars.

The statement continues: “The Postal Service is fully committed to the inclusion of electric vehicles as a significant part of our delivery fleet even though the investment will cost more than an internal combustion engine vehicle. That said, as we have stated repeatedly, we must make fiscally prudent decisions in the needed introduction of a new vehicle fleet. We will continue to look for opportunities to increase the electrification of our delivery fleet in a responsible manner, consistent with our operating strategy, the deployment of appropriate infrastructure, and our financial condition, which we expect to continue to improve as we pursue our plan.”

gordm writes: Following appeals from scientists, a Stanford and MIT study showing Diablo Canyon could save California $21 Billion, demand curtailment and a projected power supply shortfall, Gov. Gavin Newsom is now considering keeping the Diablo Canyon nuclear plant open. Diablo Canyon generated 6% of California’s total electricity in 2021 and 12% of California’s carbon-free electricity.
Elon Musk has tweeted in support of keeping Diablo Canyon open, and in support of keeping European nuclear power plants running. According to the L.A. Times, Newsom said the state would seek out a share of $6 billion in federal funds meant to rescue nuclear reactors facing closure. The money comes from the Biden administration’s recently announced effort to rescue nuclear power plants at risk of closing. “The requirement is by May 19 to submit an application, or you miss the opportunity to draw down any federal funds if you want to extend the life of that plant,” Newsom said. “We would be remiss not to put that on the table as an option.”

A spokesperson for the governor clarified that Newsom still wants to see the facility shut down long term. “It’s been six years since PG&E agreed to close the plant near San Luis Obispo, rather than invest in expensive environmental and earthquake-safety upgrades,” the report notes. “But Newsom’s willingness to consider a short-term reprieve reflects a shift in the politics of nuclear power after decades of public opposition fueled by high-profile disasters such as Chernobyl and Three Mile Island, as well as the Cold War.”

Hmmmmmm shares a report from Reuters: India will on Friday launch an open network for digital commerce (ONDC) as the government tries to end the dominance of U.S. companies Amazon.com and Walmart in the fast-growing e-commerce market, a government document showed. The launch of the platform comes after India’s antitrust body on Thursday raided domestic sellers of Amazon and some of Walmart’s Flipkart following accusations of competition law violations.

The government’s so-called ONDC platform will allow buyers and sellers to connect and transact with each other online, no matter what other application they use. It will be soft-launched on Friday before being expanded, the trade ministry told Reuters. The government document said that two large multinational players controlled more than half of the country’s e-commerce trade, limiting access to the market, giving preferential treatment to some sellers and squeezing supplier margins. It did not name the companies. The document said India’s ONDC plan aimed to onboard 30 million sellers and 10 million merchants online. The plan is to cover at least 100 cities and towns by August.

An anonymous reader shares a report: If you’d told us that Bandcamp’s acquisition by Epic Games would lead fairly swiftly to an argument with a tech giant, our money would have been on that giant being Apple. Nope. Epic Games is seeking a court injunction against Google, over changing rules on its Google Play Store for Android. Bandcamp CEO Ethan Diamond blogged about the dispute overnight, noting that since 2015, Bandcamp has used its own billing system to process payments made for music and merch within its Android app. “However, Google is now modifying its rules to require Bandcamp (and other apps like it) to exclusively use Google Play Billing for payments for digital goods and services, and pay a revenue share to Google,” wrote Diamond. “If Google’s policy changes stand, beginning on June 1st, we would have to either pass Google’s fees on to consumers (making Android a less attractive platform for music fans), pass fees on to artists (which we would never do), permanently run our Android business at a loss, or turn off digital sales in the Android app.” Diamond also said that the new policy could see a delay in payments for artists and labels, from the current 24-48 hours to “15 to 45 days after a sale,” while Epic’s filing notes that Google’s system can’t be used for purchases of physical items (merch and physical music), which would force it to use two separate payment systems anyway.

An anonymous reader quotes a report from Motherboard: In the latest effort to challenge Amazon’s grueling labor practices, a new bill, that was introduced on Friday, would require New York employers to disclose and place limits on productivity quotas for warehouse workers. The New York bill, known as the Warehouse Worker Protection Act, is an expanded version of a similar first-of-its-kind law that passed in California last year aimed at Amazon that regulates warehouse worker productivity quotas. The legislation is in part a response to skyrocketing injury rates in Amazon warehouses linked to productivity expectations. Recent data shows that workers in the e-commerce warehousing industry in New York experience serious work-related injuries at three times the average rate for private industry in the state, according to OSHA data.

The New York bill would require employers with at least 50 employees in a single warehouse or 500 workers statewide to share a written description of productivity quotas, how the quotas are developed, and how they can be used for disciplinary purposes with each worker. It would also ensure that production quotas do not interfere with workers’ basic rights such as bathroom breaks and rest periods or health and safety laws. […] Amazon has provided little transparency into how productivity “rates” that are designed by algorithms are formulated, but said that it creates productivity targets for workers that are based on their experience and take into consideration health and safety. […] The bill takes California’s law a few steps further by requiring employers to develop and implement an injury reduction program with worker input that identifies and addresses job hazards, such as rapid pace and heavy lifting, that can cause musculoskeletal injuries. This includes a worksite evaluation by an ergonomics consultant and worker training on how to avoid injuries. “The Warehouse Worker Protection Act will give workers in this industry — union or not — the ability to demand that their health and bodily integrity is accounted for, and not sacrificed for profits they do not get to share in,” said Jessica Ramos, the bill’s author and a New York state senator from Queens. “As the senate labor chair, I see it as my responsibility to clear the path for any worker who needs to stand up to an abusive employer.”
