Long After Pluto Fly-By, NASA's New Horizon's Probe Wakes Up Again, Starts Doing New Science

3 months 2 weeks ago
Launched in 2006, NASA's New Horizons probe flew by the planet Pluto in 2015. But this week it "awakened from its longest sleep ever," reports CNN. It's now 5.9 billion miles (9.5 billion kilometers) from Earth... NASA's New Horizons spacecraft went into a planned hibernation mode on August 7, 2025, and woke up on June 23 using commands stored on its main computer. The mission's flight controllers at the Johns Hopkins University's Applied Physics Laboratory in Laurel, Maryland, confirmed that New Horizons is in great shape and ready to transmit a stream of science data gathered during hibernation from its location in the region of icy objects known as the Kuiper Belt. Pluto is the largest of thousands of frozen, rocky bodies called trans-Neptunian objects, or TNOs, that exist in the Kuiper Belt at the edge of our solar system — remnants from its formation 4.5 billion years ago... The spacecraft is capturing data about the rotation rates, orientations and shapes... The measurements provide insights into how planets are born from dust and pebbles, said Pontus Brandt, New Horizons project scientist at the Johns Hopkins Applied Physics Laboratory. "There seems to be more paired, snowman-shaped bodies, like Arrokoth, out there than anyone expected," Brandt wrote in an email. "Are such binaries the most common planetesimal and is this how larger planets have been built in our own and other stellar systems? These are very deep questions that New Horizons can help answer." The spacecraft also measures the distribution of gas in the outer heliosphere, the expansive, protective bubble formed by a steady stream of particles that release from the sun called the solar wind. Meanwhile, an instrument called the Pluto Energetic Particle Spectrometer Science Investigation is measuring galactic cosmic rays, extremely fast particles created when stars explode. The particles pose one of the more severe threats for human activities in space, Brandt said, but the boundary of the heliosphere acts as a shield to protect our solar system from 70% of them. New Horizons' data could help scientists learn more about how this puzzling shielding works, he said. Another instrument, the Venetia Burney Student Dust Counter, has collected data that has thrown New Horizon's team a curveball, Brandt said. The team expected dust abundance to be high within the Kuiper Belt due to the significant presence of small objects. But New Horizons has traveled beyond the known boundary of the Kuiper Belt — and it's still in a dusty environment.

Union Fights Microsoft Over Layoffs at Game Studios

3 months 2 weeks ago
Thursday the union that helped organize thousands of workers across numerous Microsoft-owned video game studios filed unfair labor complaints against Microsoft over the layoffs of 1,600 employees. The gaming news site Aftermath says the complaints allege unlawful action: "Xbox management is required to bargain with the union over the decision of layoffs prior to implementing them during the status quo period, and we are pursuing every available avenue to protect our members," a Communications Workers of America spokesperson said in a statement to Aftermath... Speaking to Game Developer, CWA Canada president Carmel Smyth elaborated on the unions' misgivings... "Basically the employer cannot arbitrarily change working conditions while it is engaged in negotiating with the union. We will continue to file legal challenges if necessary, and do all we can to defend the rights of Bethesda Game Studios workers...." "I'm very proud of the hard work the bargaining committees and CWA staff have put in to evaluate the legality of how the layoffs were conducted," a current id Software employee and union member told Aftermath. "It's important, even for the world's largest and most profitable companies, that there are consequences for violating federal labor law. If we hadn't explored this avenue to hold Microsoft accountable, it would be a sign to all other game executives that they can break the law and get away with it." Legal action is just one part of unions' larger effort to hold Microsoft accountable for its decision to lay off thousands of workers. This week, CWA also hosted a series of "Save Our Devs" demonstrations outside the offices of affected studios like Zenimax, id Software, Bethesda, and Obsidian.
