#aas235 starlink

Jeff Hall: eight telecons to date between AAS committee and SpaceX on Starlink brightness issues, and in-person meetings at this conference. #AAS235

Excellent thread summarizing the discussion and take-away points from the Starlink/Space-X session at #AAS235 : https://twitter.com/vbaldassare/status/1215005236797964288 …

Seitzer: “cheer up, the worst is get to come”. If the starlink constellation was going to stop at 1584, we could handle it. But there are plans for 10-20 times that, from SpaceX and others. #AAS235

User downlink from starlink uses 10.7-12.7 GHz and will have to coordinate with radio astronomy. #AAS235

#AAS235 HOT TAKE: compromise by putting a space telescope on the back of each starlink satellite

Pat Seitzer from the University of Michigan: the problem with the Starlink satellites is that they are brighter than 99% of the objects that are in Earth orbit. With 1500 of them going into orbit "life is about to get really interesting" #AAS235

The @VRubinObs (formerly LSST) will be very impacted by Starlink. Original Starlink design will saturate detectors. They are trying to fix this. #AAS235

P. Cooper from SpaceX emphasizes that the brightness of the original Starlink satellites came as a surprise and they are committed to mitigating the effects. #AAS235

New Satellites in mega constellations (starlink) are brighter than 99% of objects in orbit. Starlink has already doubled the number of visible (to humans) objects. #aas235 okay now, concern is increase by 10 times or more.

Live report from the #AAS235 special session discussing impact of mega-constellations, like #Starlink. https://twitter.com/vbaldassare/status/1215005236797964288 …

Starlink wrecks havoc on astro dectors. That’s a valid argument. I’m just not buying that seeing a few satellites along w the planes & everything else is going to wreck our relationship w the sky. There are concerns, but ... Starlink = internet to impoverished people. #AAS235

That StarLink satellites could be breaking international guidelines on radio interference is inexcusable. There is a difference between being a nuisance because they are more reflective then known, and purposely creating a signal that knocks out chunks of the radio sky. #AAS235

Second, astronomical observations at radio wavelengths are threatened through radio leaks. Third, the increasing number of satellites creates a potentially critical problem whose impact must be better understood before large constellations are launched #AAS235 #Starlink
