Jupiter Accelerates Electrons to Near-Light Speed, Offering Clues to Cosmic Ray Origins

As planets and stars travel through the streams of charged particles flowing across space, their magnetic fields act like obstacles; incoming particles are slowed and deflected, forming a boundary called the bow shock; just ahead of this boundary lies the foreshock, a variable region where magnetic conditions can accelerate some particles to nearly the speed of light.

The giant planet’s bow shock isn’t just deflecting the solar wind, it’s acting as a powerful particle accelerator, firing electrons to relativistic energies of at least 1 MeV, according to a new analysis of data from NASA’s Juno spacecraft.

The saga of the International Space Station air leak took a worrying turn Friday

Five of the seven crew members on the International Space Station briefly sought refuge inside a SpaceX return capsule Friday morning as two Russian cosmonauts worked on an air leak on the other end of the complex.

NASA ordered US astronauts Jessica Meir and Jack Hathaway, French astronaut Sophie Adenot, and Russian cosmonaut Andrey Fedyaev into SpaceX's Crew Dragon Freedom spacecraft around 9 am EST (14:00 UTC) on Friday. The foursome launched aboard the SpaceX crew capsule on the Crew-12 mission in February, and the ship serves as their lifeboat until the crew's scheduled return to Earth in September.

NASA astronaut Chris Williams, who flew to the station in a Russian Soyuz ferry ship, joined the Crew-12 astronauts inside the Dragon spacecraft.

ISS crew back to normal after emergency shelter order

NASA has told crew aboard the International Space Station (ISS) to resume normal operations, ending a roughly two-hour period in which five astronauts sheltered inside a docked SpaceX capsule. The shelter order came Friday morning as a precautionary measure to protect crew while Russian cosmonauts attempted a fix on the Zvezda service module’s transfer tunnelContinue reading "ISS crew back to normal after emergency shelter order"

Jason Momoa’s 1920s Harleys become electric hybrids in wildest EV conversions yet

UK-based EV conversion specialist Electrogenic has converted five of Jason Momoa’s cherished vintage vehicles to electric power — including three 100-year-old Harley-Davidson motorcycles reimagined as plug-in hybrids. The builds are featured in Season 2 of Momoa’s HBO documentary series On The Roam, streaming now.

The project includes two extremely rare classic Land Rovers converted to all-electric drive with 150+ miles of range, a battery-equipped off-grid camping trailer, and the three Harleys that can switch between electric, petrol, and combined hybrid power on the fly. Electrogenic is now selling conversion kits for both the Land Rovers and the Harleys.
