NASA's Chandra Releases 'Red, White, and Blue' Universe for US 250th (Chandra + Webb)

In this image of Cassiopeia A, X-rays from Chandra (represented in blue and purple) have been combined with an infrared image from NASA’s James Webb Space Telescope (red and white). Chandra’s X-ray vision reveals the blast wave that tore through the star, as well as elements in the debris field like iron, calcium, and oxygen. Webb’s infrared data also shows the expanding shell of material from the explosion and cosmic dust throughout the remnant.

Image description: Cassiopeia A occupies the top panel of the frame, significantly larger than the other images in the set. The cloudy blast-wave of the supernova remnant is ring-like in shape, streaked with veins of iron, calcium, and oxygen. Here, presented in red, white, and blue, the remnant resembles an electrified donut, crackling with marbled veins of strawberry and blueberry icing.

Sony will kill PlayStation games on discs in 2028 and offer digital downloads only

With the much-anticipated release of Grand Theft Auto VI only available as download, Sony is following suite

Sony said on Wednesday that it would stop releasing new video games for the PlayStation console on disc in January 2028 following a shift in consumer preferences.

“Following this date, new games will be available on PlayStation Store and at retailers in digital formats only,” the company said on its official PlayStation blog.

NASA Wants To Send Spare Nuclear-Powered Mars Rover To the Moon

An anonymous reader quotes a report from Space.com: NASA provided an Artemis update today (June 30), announcing new lunar landing contracts for its Moon Base initiative and a surprise new possible rover mission that could be headed to the moon's south pole. During the second monthly update that NASA has provided for its moon base plans, the agency named Astrobotic, Firefly Aerospace and Intuitive Machines as the providers of four robotic landers that will deliver scientific payloads to the surface of the moon, as NASA tests and expands the technologies needed for a permanent human outpost. "This is this drawing on the playbook that worked very well for NASA during the 1960s," NASA Administrator Jared Isaacman said during the livestreamed update, explaining the experiential approach to a crewed lunar return. "We didn't just jump right to Apollo 11."

Isaacman also announced the potential repurposing of an engineering development model built to mirror the agency's Perseverance and Curiosity rovers on Mars. "There is another," Isaacman said, quoting Yoda's line from "Star Wars: The Empire Strikes Back." That test rover is called PROMISE, short for "Polar Rover for Observation, Mapping, and In-Situ Exploration" (though it was formerly known as Optimism). PROMISE was developed at NASA's Jet Propulsion Laboratory (JPL) in Southern California, where it has been used as a test platform for fixes or commands that engineers want to try on the ground before permanently sending them to Perseverance and Curiosity. Now, NASA wants to send PROMISE on a mission of its own. Though sending PROMISE to the moon would leave Perseverance and Curiosity -- both of which remain active on Mars -- without an Earth-based testbed, Isaacman thinks it would be worth it. "We've had years now of experience operating the two rovers on the surface of Mars, and we've got this hardware that the taxpayers have invested a lot in," he said. "So the question was posed: 'What if we send it to the moon?'"

With a little refurbishment, PROMISE would help advance NASA's lunar plans, Isaacman added. Like Perseverance and Curiosity, the test rover is powered by a radioisotope thermoelectric generator (RTG), which converts heat from naturally decaying radioactive material into electricity. So it wouldn't require sunlight to operate -- a real benefit on the moon, where most locations experience long stretches of darkness. (NASA plans to build its Artemis base near the moon's south pole, which is thought to harbor an abundance of water ice and also has a relatively complex lighting environment.) The other robots currently in the works to launch on future missions to the moon, including the landers announced during today's update, are all solar powered. Through 2029, NASA hopes to launch up to 20 such missions as part of the CLPS (Commercial Lunar Payload Services) initiative to support the first phase of the agency's moon base plans, and the landers announced today will be some of the first in that lineup.
