The James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) has four observing modes. On Aug. 24, a mechanism that supports one of these modes, known as medium-resolution spectroscopy (MRS), exhibited what appears to be increased friction during setup for a science observation. This mechanism is a grating wheel that allows scientists to select between short, medium, and longer wavelengths when making observations using the MRS mode. Following preliminary health checks and investigations into the issue, an anomaly review board was convened Sept. 6 to assess the best path forward. The Webb team has paused in scheduling observations using this particular observing mode while they continue to analyze its behavior and are currently developing strategies to resume MRS observations as soon as possible. The observatory is in good health, and MIRI’s other three observing modes – imaging, low-resolution spectroscopy, and coronagraphy – are operating normally and remain available for science observations.
Determine what kind of mass/velocity we would need to deflect and asteroid in event of a imminent collision, or if it's even feasible at all. Mission was a huge success, now we measure how much difference we made in this asteroids path.
Enjoyed some nice time stargazing tonoght and enjoying views of Jupiter and Saturn with my Orion XT8. Kids had a blast. I need to get one of those attachments that let you take pictures with your phone
They're not necessarily aligned, just lucky timing with their orbits that they're not in front or behind Jupiter relative to us. I know that's what they are through the use of this newfangled contraption called the internet. Joking aside, my camera wouldn't be able to pick up any of the dozens of smaller moons, so it would be a safe bet that they were the Galilean satellites even if I didn't look it up. From left to right it's Ganymede, Europa, Io, and Callisto way the hell off to the right.
So when do we find out about the big one heading towards earth? Jk but when do we find out this works?
