All mission instruments have successfully deployed, and SPHEREx and PUNCH mission teams will wait to confirm signal. Watch as SPHEREx slowly moves away from the rocket's second stage and begins its journey.

Queensland, Australia faced widespread flooding after Ex-Tropical Cyclone Alfred struck. This Copernicus EU Sentinel-1 radar composite image shows the extent of the flooding with flooded areas in red - it was created using two images: one from before and one after the floods.
