Perseverance Checks In From Mars With A Selfie, The Mounting Pollution From Satellite Launches, And More Science Stories

NASA’s Perseverance rover captured its sixth selfie while exploring new terrain west of Jezero Crater on Mars.

The rover is working in a scientifically rich region as scientists continue studying Mars’ ancient landscape and history.

Separately, researchers warned that booming satellite megaconstellation launches could release more soot into the upper atmosphere.

That pollution could slightly cool the climate by 2029, raising new concerns about the environmental cost of growing launch traffic.
