Northrop Grumman has launched a private satellite-servicing mission to attach life-extending "jetpacks" to aging communications satellites in geosynchronous orbit. "It's the second satellite-saving mission to launch this month, all part of a growing, money-saving effort to keep spacecraft running as long as possible," reports Phys.org. From the report: Launched by SpaceX, Northrop Grumman's mission robotic vehicle -- dubbed MRV -- and its jetpacks will spend the next year angling into the proper orbit 22,300 miles (36,000 kilometers) above Earth. Hundreds of satellites orbit at this so-called geosynchronous orbit, where they match the speed of Earth's rotation and keep to the same part of the sky for continuous coverage. Once in place by mid-2027, the minivan-sized spacecraft will use its 10-foot (9-meter) arms to attach a jetpack to an aging communication satellite. Then it will zip off to two more satellites in need. For its debut flight, the spacecraft was accompanied by three electric-propelled jetpacks that peeled away separately following liftoff. Like the MRV, the jetpacks will use their own xenon gas thrusters to get to the desired orbit. Once in place, the jetpacks will wait for the robot to grab them, one at a time, and plug them into their designated satellites. Each jetpack -- the size of a washing machine -- will provide the necessary oomph for an out-of-gas satellite to keep operating for several more years instead of retiring. If it works, it will be a boon for satellite operators SES of Luxembourg and Optus of Australia, saving them millions of dollars in replacement costs.

Longtime Slashdot reader BeaverCleaver shares a report from the BBC: The wreckage of a Pan American Airways plane has been found 74 years after it plunged into the Atlantic Ocean in a crash that prompted mandatory airline safety briefings. The Clipper Endeavor was found 2,000ft (610m) below sea level off the coast of Puerto Rico with a sonar-equipped drone. It went down on April 11, 1952, following multiple-engine failure shortly after take-off. Everyone onboard survived the impact -- but passengers struggled to locate life vests and rafts as the plane rapidly sank. Of the 69 passengers and crew onboard, just 17 survived. The disaster led to sweeping reforms in aviation safety, including compulsory pre-flight safety briefings on every commercial flight. [...] Today, before every commercial flight, cabin crew are required to outline where a plane's exits are, as well as the location of life vests and how to inflate them.

"General Motors has been pulling a Tim Cook and boosting its software and subscription business," reports Business Insider. During the automaker's Tuesday earnings call, executives said they're increasingly leaning on software subscriptions like OnStar and Super Cruise to generate high-margin recurring revenue long after customers buy their vehicles. GM says OnStar brought in about $800 million in the second quarter, while Super Cruise revenue grew about 70% year over year. From the report: GM says its software business keeps roughly 70 cents of every dollar it brings in. That's a rare level of profitability in the auto industry, as many car sales generate just four to 10 cents per sales dollar. [...] GM expects to add about 1 million OnStar subscribers this year, bringing the total close to 13 million. Super Cruise, GM's hands-free, eyes-on driving system, is growing even faster. GM added about 70,000 subscribers during the quarter and expects to end the year with more than 850,000. Revenue from the service increased about 70% from a year earlier. And a lot of drivers are sticking around after the free period ends. GM said between 30% and 40% of eligible owners continue paying after their included three-year Super Cruise subscription expires. [..] "We do think we have tremendous levers, multiple levers of growth," Barra said on the call. "We definitely think there's a lot of opportunity at GM to grow, improve margins, and become less cyclical." "Software and services are becoming increasingly important to how customers experience GM vehicles and how we deliver value beyond the initial purchase," a spokesperson previously told Business Insider. "As vehicles become more software-defined, we can introduce new digital experiences through updates and optional services rather than hardware changes."
