Okay, maybe this won’t shine right away. NASA has published A more detailed analysis of the damage suffered by the James Webb Space Telescope in an exercise with a micrometeoroid and considered the damage “irreparable”. Any damage to the JWST is uncorrectable, at least in the sense that the Hubble Space Telescope can be equipped with optics to fix exactly its yet-to-be-mistaken main mirror. JWST is too far for a service call, so in this case correctability refers to a combination of what can be done by changing the shape and position of the affected mirror segment and what can be taken care of with image processing. In a total of six collisions in the six years Webb has been at the station, damage to the C3 segment, as well as damage to other segments, is assessed by “wavefront detection”, which looks at how out of phase the light from each of them is. mirror segment. The damage sounds bad, and it must have been absolutely painful for the technicians and engineers who built this thing with love and care to see it sink anyway, but in the long run, that damage shouldn’t hinder Webb’s long-term scientific goals.

In other space news, we hear this most Patience the rover got its first piece from the ancient river delta in Jezero Crater. The rover was looking for something interesting to sample, but everything he tried with his abrasive tool was either too fragile, too hard to reach, or scientifically boring. Eventually the rover found a good spot to drill and was able to bring in a 6.7 cm core sample. This makes it the tenth core sample collected overall and the first from the delta region thought to have the best chance of containing evidence of ancient Martian life.

Closer to home, we’ve all heard of robotic surgery, but the image that comes to mind doesn’t quite match reality. Robot-assisted surgery is probably the better term because surgical robots are ultra-precise remote manipulators, often guided by a skilled surgeon. But if A study on surgical robot performance If there are any signs, the days of human surgeons may be numbered. The study compared the accuracy and speed of both a human surgeon controlling a standard Da Vinci surgical robot and a depth camera to detect a stand-alone autonomous version of the robot. Using a standardized test of surgical skill, the autonomous system matched human surgeons for failures—luckily, no “oopsies” for either—but bested humans for speed and positional accuracy. It’ll probably take some time before fully autonomous surgeons become a thing, but we’re not going to bet against it in the long run.

Most of the readers have no doubt heard the exciting news: Supercon will return this year as a personal event! Make sure you book the first weekend of November to make the pilgrimage to Pasadena – it’ll be great to see everyone again after a long hiatus. But if you can’t wait until November for an IRL scam, consider stopping by. SCALE 19XComing this week in Los Angeles. The Southern California Linux Expo is held July 28-31 and hosts a number of speakers, including the keynote by Vint Cerf. Hackaday readers can save 50% on tickets with the HACK promo code.

And finally, as someone who loves Easter eggs of all kinds, we especially appreciated the hidden message in the software variety. tribute to this easter eggembedded art that has served as a creative outlet for programmers over the years. The article lists a few great examples of the art form and explains why they are truly important works of the tech world and what they do. We tried a few that we have listed in the article and have not heard of before; some hits, some misses, but all are appreciated. Well, most – the corporate rah-rah type, as far as we’re concerned, can immediately bore you.
