hubie writes:NASA has been preparing for a wet dress rehearsal for the Artemis I rocket, but have hit several issues causing delays, the most recent being a faulty helium gas check valve. They have now announced that a modified wet dress rehearsal will start with a call to stations on April 12. This rehearsal proceeds through as an actual launch activity that scrubs at the T-10 second point. The modified test will focus on filling the core stage with cryogenic propellant, but with minimal propellant operations on the interim cryogenic propulsion stage (ICPS). Following the test, the rocket will be returned to the Vehicle Assembly Building to replace the helium check valve as well as to assess the launch procedures.NASA is streaming live video of the rocket and spacecraft on the Kennedy Newsroom YouTube channel.Original SubmissionRead more of this story at SoylentNews.

canopic jug writes:Raspberry Pi OS "Bullseye" is getting some changes to improve its robustness. Gone is the default user 'pi' with the default password of 'raspberry'. On first-boot, a setup wizard walks through setting a normal user with a regular password, though there are still options for headless installation. Among other improvements, it is now also possible to do the setup with a bluetooth mouse/keyboard exclusively. The old way required at least a wired mouse, if not also a wired keyboard, to connect first.

JoeMerchant writes:Digital Data Could Be Altering Earth's Mass Just a Tiny Bit, Claims PhysicistAccording to calculations made a few years ago by University of Portsmouth physicist Melvin Vopson, the literal mass of visual imagery created daily – along with half a billion tweets, countless texts, billions of WhatsApp messages, and every other bit and byte of information we've created – could be making our planet a touch heavier. An experiment recently proposed by Vopson based on antimatter explosions might go some way in convincing the scientific community that information might not only have mass but that it could also be a strange new state of matter, or (of course) the elusive dark matter needed to balance most cosmological observations today.Scientist says that dark matter may be information itself
