NASA warns FCC on impact with Observations from Earth , observations
from Hubble and other satellites due to all the contellations at
different altitudes PSaceX wants to deploy. Says their imagery is
already impacted by Starlink satellites.
Also, and I had raised that issue before but was dismissed here: NASA
worries about new Starlink at about 328-360km which would limit launch opportinities and profiles for ships going to ISS because vehicles spend
more time do do orbit phasing at that altitude.
