Olivier Hainaut

“Hainaut had previously modeled the broader effect of Reflect Orbital’s beams, finding they would brighten the sky up to 300% worldwide.”

“A new study by the European Southern Observatory warns that plans to launch more than 1.7 million satellites into orbit could have “devastating consequences for astronomy,” making the night sky brigh…”

“Hainaut found that SpaceX’s mega-constellation could create dozens of satellite trails in images taken by ESO’s Very Large Telescope in Chile two hours into the night.”

“If you have a 10 percent increase in light pollution, you have to increase all the exposure times by 10 percent.”

“For a 100 percent increase in light pollution, you have to increase all the exposures by 100 percent.”

“This is not a hard number, like 99 999 is good and 100 001 is bad: clearly I’d prefer 50 000,”

“100 000 causes losses at about the level of other technical losses, such as equipment failure.”
