Fewer streaky photos of the sky? NSF and SpaceX hope so.
found that 5,301 satellite streaks showed up in archival observations captured at the Zwicky Transient Facility in California between November 2019 and September 2021.
"In 2019, 0.5% of twilight images were affected, and now almost 20% are affected," Przemek Mróz, a former Caltech postdoctoral scholar and the study's lead author, said in aTo mitigate this, SpaceX has already begun working on redesigns for its second-generation Starlink satellites, including solar array mitigation, dielectric mirror film and a new kind of black paint for its satellites that it hopes will reduce brightness.
SpaceX also agreed to look at just how much of an effect, if any, the lasers that NSF facility use to sharpen their instruments' vision actually affect the operation of a satellite. Observatories had been turning off their lasers whenever a Starlink satellite was nearby, but that won't be necessary any longer, according to the statement.
SpaceX is addressing the concerns of radio astronomers as well as optical. The company has agreed to a number of coordination efforts since Starlink satellites use a radio band very close to that used for radio astronomy. In addition, the company has agreed to study the impact of Starlink terminals located near the
