Satellites are leading the charge in the battle against climate change, providing critical insights about Earth that can only be gained from space. But are they also contributing to the problem?
Putting aside environmental impacts of the rockets that launch them to orbit, satellites inject a complex mix of chemicals into the atmosphere when their computers, fuel tanks and other onboard materials vaporize upon reentry.
Latin America looks to space, despite limitations on ground

Mars missions, astronauts coming and going at the International Space Station, China's increasingly ambitious space program. Space-related news is flowing, and not just from the world's richest, biggest nations. Take Latin America.
On Feb. 17, the congress in Nicaragua, one of the region's poorest, most conflict-prone nations, approved a law creating a space agency. Costa Rica, known for relative growth and stability, did the same on Feb. 18, the day that the NASA rover Perseverance landed on Mars to look for signs of ancient life.

A SpaceX Crew Dragon capsule carrying four astronauts back to Earth splashed down off Panama City early Sunday, a NASA livestream showed.
Boats were retrieving the spacecraft and crew after their six-month mission aboard the International Space Station.
The crew reported they were feeling well, NASA said.
