Satellites are increasingly interfering with optical and radio astronomy, prompting the coordinated response.
messing with optical and radio observations. Long exposures at optical wavelengths are particularly affected; research from last month found ain the number of images taken during the twilight hours that contained streaks caused by Starlink satellites. That’s a problem for astronomy, but also for our security; views of the horizon at dusk and dawn are critical for detecting threatening near-Earth objects.
Accordingly, the group will call upon astronomers, satellite operators, government regulators, and the wider community to get involved. Satellite companies will be asked to provide more information about their space-based assets, such as coordinates and predicted movements. The group will also help astronomers to deal with associated problems, like providing software to remove visual artifacts from telescope images.
“It’s a not a question of satellites versus astronomy, but rather how to mediate the different needs and interests and values that coalesce in outer space, including those that are less powerful,” she explained. “This requires open dialogue and coordinated and collective action. The international astronomy community is showing us how to do this. And the world is listening. This is a critical moment for space governance.”This is a good and necessary starting point.
