Mega-Constellation Environmental Issues Need Examining, Group Says

If all the mega-constellation proposals come to pass, then as many as 29 tons of satellites could reenter the atmosphere daily, the U.S. Public Interest Research Group said last week. Before that happens, the environmental impacts must be understood, PIRG added. "We need to look before leaping" and require an environmental review as well as an upper limit on how many satellites can be deployed, PIRG said.
