Study: Current, future megaconstellations risk space-based astronomy
a–d, Simulated exposure for Hubble (a), SPHEREx (b), Xuntian (c) and ARRAKIHS (d) space observatories, showing sectors affected by satellite trail contamination. The satellite trails represent the effects of the planned satellites using the orbital and physical parameters of the announced constellations to be operational by 2040. Background galaxies were modelled on the basis of…

Despite gyro failure, NASA says Hubble Space Telescope still up to world-class science
The Hubble Space Telescope is seen after its release from the space shuttle Columbia during a 2002 servicing mission. Credit: NASA Trouble with one of the Hubble Space Telescope’s three remaining gyroscopes, critical for aiming and locking onto targets, has prompted mission managers to switch to a backup control mode that will limit some observations…
