Report outlines measures to reduce impact of satellite constellations on astronomy
A new report offers ways both astronomers and satellite developers can reduce the effect megaconstellations have on ground-based astronomy, but warned that no combination of measures can entirely eliminate the problem,
OneWeb’s revival worries astronomers
A potential return to operations of satellite megaconstellation company OneWeb is a new source of worry for astronomers who previously had been focused on the effect SpaceX’s Starlink satellites will have on their observations.
Astronomers warn about effects of other satellite megaconstellations
Astronomers who have spent the last year worried about the effect that SpaceX’s Starlink satellites will have on their observations say they are increasingly concerned about the impact from other proposed megaconstellations.
SpaceX to add sunshades to all future Starlink satellites
SpaceX has decided to add sunshades to future Starlink satellites to reduce their impact on astronomy, having opted for constellation-wide implementation of the reflective hardware.
Senators ask GAO to review FCC oversight of satellite constellations
Two senators have asked the GAO to review the FCC’s decision to exempt satellite constellations like SpaceX’s Starlink from an environmental review, given those satellites’ effect on the night sky.
SpaceX claims some success in darkening Starlink satellites
SpaceX says it will take more steps to reduce the impact of its Starlink satellite constellation on astronomy, although astronomers disagree with statements by Elon Musk that the system will have “zero” effect on their work.
Starlink vs. the astronomers
Since the first Starlink satellites launched in May, astronomers have complained that those satellites, and potentially other systems to be launched in the next few years, could make it far more difficult for astronomers to conduct observations using ground-based telescopes.
SpaceX, astronomers working to address brightness of Starlink satellites
SpaceX says it’s committed to working with the astronomy community to address the brightness of its Starlink satellites, but some astronomers remain concerned about the deleterious effect that system and other megaconstellations will have on their field.
Radio astronomers worried about OneWeb interference
Radio astronomers say OneWeb has not, until recently, paid attention to their concerns about interference, but that it is not too late to avoid a spectrum conflict.
Little legal recourse for astronomers concerned about Starlink
Despite complaints by individual astronomers and astronomical organizations, legal experts say there is little they can do under existing federal law and regulations to halt the deployment of SpaceX’s Starlink satellites.
