JoeSchmuckatelli Posted June 8, 2022 Share Posted June 8, 2022 (edited) Between May 23 and 25, NASA’s James Webb Space Telescope sustained an impact to one of its primary mirror segments ... This most recent impact was larger than was modeled, and beyond what the team could have tested on the ground. ... After initial assessments, the team found the telescope is still performing at a level that exceeds all mission requirements despite a marginally detectable effect in the data This recent impact caused no change to Webb’s operations schedule, as the team continues to check out the science instruments’ observing modes and prepares for the release of Webb’s first images and the start of science operations From the blog (FWIW - my pucker factor was high as I read about this) Edited June 8, 2022 by JoeSchmuckatelli Quote Link to comment Share on other sites More sharing options...

HvP Posted June 8, 2022 Share Posted June 8, 2022 (edited) 2 hours ago, JoeSchmuckatelli said: James Webb Space Telescope sustained an impact to one of its primary mirror segments It seems obvious in retrospect, but the larger the surface area the greater the risk of random collisions. The NASA Webb team naturally have studied the risk, but there is always the unlucky possibility that an outlier in size or momentum will hit something sensitive. Fortunately, having a bigger mirror surface is itself a form of redundancy in a way. Edited June 8, 2022 by HvP Quote Link to comment Share on other sites More sharing options...
RCgothic Posted June 9, 2022 Share Posted June 9, 2022 (edited) Annoying for it to happen this soon into the mission though. Hope it's an outlier rather than evidence of a generally more hostile than planned environment. Edited June 9, 2022 by RCgothic Quote Link to comment Share on other sites More sharing options...

JoeSchmuckatelli Posted June 12, 2022 Share Posted June 12, 2022 (edited) July 12 is the scheduled date for release of color images from the team. "The first two instrument modes, NIRCam imaging and NIRISS imaging, have been declared ready for science; watch the “Where is Webb” page as the team works their way through the other 15 instrument modes. After commissioning is finished, the fun – and discoveries – will start: implementing the hundreds of peer-reviewed science programs that have been selected for Webb’s first year. The area on the sky that Webb can see at any given time is called the field of regard. Deciding which observations to make on which day is a complicated process designed to optimize observational efficiency and manage the observatory’s resources" My reading suggests that early priority is being given to certain projects that, together, will showcase the range of science that Webb can provide as inspiration for the community... To stimulate new proposals and, perhaps novel science. Edited June 12, 2022 by JoeSchmuckatelli Quote Link to comment Share on other sites More sharing options...

JoeSchmuckatelli Posted June 18, 2022 Share Posted June 18, 2022 (edited) we are featuring MIRI’s medium-resolution spectroscopy mode and sharing our first spectroscopic engineering data. Once the spatial alignment and image quality of the several bands are well characterized, the MIRI team will prioritize calibrating the spectroscopic response of the instrument. This step will include determining the wavelength solution and spectral resolution throughout each of the twelve fields of view using observations of compact emission-line objects and diffuse planetary nebulae ejected by dying stars. We show the exceptional spectral resolving power of the MRS with a small segment of a spectrum obtained from recent engineering observations of the active galactic nucleus at the core of Seyfert galaxy NGC 6552. Once these basic instrument characteristics are established, it will be possible to calibrate MRS so that it is ready to support the wealth of Cycle 1 science programs due to start in a few short weeks.” (From the blog) ... Looking like Webb might offer a tad more granularity than Spitzer. Edited June 18, 2022 by JoeSchmuckatelli Quote Link to comment Share on other sites More sharing options...
