NASA delays dress rehearsal of new megarocket

Today, NASA suspended the last major test of its Space Launch System (SLS) rocket after pressurization issues prevented technicians from safely loading propellants into the rocket. The test — known as a wet dress rehearsal — has been postponed until Monday, April 4th at the earliest, NASA announced in a post on the Artemis I live blog.

“Teams have decided to scrub tanking operations for the wet dress rehearsal due to loss of ability to pressurize the mobile launcher,” NASA explained. Some fans on the mobile launcher — the platform that provides support for the rocket up until launch — were unable to maintain positive pressure, which is crucial in warding off hazardous gases. As a result, NASA technicians couldn’t “safely proceed” with the fuel-loading process.

This type of dress rehearsal gets its “wet” label since it’s essentially a run-through of all the procedures NASA will have to carry out when the first actual launch of SLS takes place, including filling the 322-foot rocket with 700,000 gallons of propellant. In a press conference on Sunday evening, NASA said its team is currently on the launchpad attempting to troubleshoot the issue. The agency says it’s on track to resume the wet dress rehearsal tomorrow.

The test originally began on April 1st at the Kennedy Space Center in Florida and was supposed to wrap up on Sunday. NASA encountered some rough weather Saturday night, as lightning struck the towers around the SLS’s launchpad. Jeremy Parsons, the deputy program manager at NASA’s Exploration Ground Systems, said one of these strikes was one of the strongest NASA has seen since installing the lightning protection system. “It hit the catenary wire that runs between the 3 towers,” Parsons wrote in a tweet from the EGS Twitter account. “System performed extremely well & kept SLS and Orion safe.”

The SLS is supposed to carry the Orion spacecraft on an uncrewed mission around the Moon as part of the Artemis program, a flight called Artemis I. That mission, tentatively scheduled for this summer, is supposed to get the rocket — and NASA — ready for the mission that will eventually carry humans to the lunar surface.

You can keep checking back for updates on the test on NASA’s live blog, as well as on the agency’s Twitter.

U.S. Government Sues Adobe for Hidden Termination Fees When Canceling Subscription

The United States Department of Justice and the Federal Trade Commission today levied a lawsuit against Adobe [ PDF ] for imposing a hidden termination fee on subscribers who want to cancel their Adobe plans. Adobe is accused of forcing subscribers to "navigate a complex and challenging cancellation process designed to deter them from cancelling subscriptions they no longer wanted." Adobe offers its Creative Cloud products on a subscription basis, with fees that are paid monthly. A monthly payment suggests that it's possible to cancel anytime, but that's not how Adobe works because most customers are actually locked into a hidden annual agreement. Customers who sign up for a free trial and are then charged and signed up to the default Creative Cloud plan, which is actually an annual contract. Canceling the annual contract requires customers to pay a lump sum of 50 percent of the "remaining contractual obligation" to cancel, despite the fact that servic

iOS 18 Introduces More Charging Limit Options on iPhone 15 Models: 85%, 90%, and 95%

All four iPhone 15 models feature a setting that prevents the devices from charging beyond 80% while toggled on, which can potentially improve an iPhone battery's lifespan by reducing the time that the battery is fully charged. And with iOS 18, Apple has taken this feature a step further by adding new 85%, 90%, and 95% charging limit options. Screenshot: Aaron Perris The feature can be found in the Settings app under Battery → Charging. The charging limit feature remains exclusive to the iPhone 15 lineup on the first iOS 18 beta, with the option not found on the iPhone 14 Pro or older. The first iOS 18 beta is now available for Apple Developer Program members, and a public beta will follow in July. Following beta testing, the update should be widely released to all users with an iPhone XS or newer in September.
