Mark McCaughrean | Still it’s still Friday in French Guiana, from where the NASA/ESA/CSA # JWST was launched on Christmas Day 2021, we can still celebrate the observatory’s 1000th day in space 🎉 A remarkable achievement for science & technology: as Lee Feinberg noted over on the Other Place, the telescope continues to deliver an image performance twice as good as requirements & none of the primary mirror actuators have needed adjusting since April 2, despite a planned cadence of fortnightly. # SpaceScience 🚀🛰️✨
