NASA employees are preparing plans to terminate two critical satellite missions monitoring greenhouse gases, which provide valuable data to various sectors, including agriculture and science.
"Finding a temperate planet in such a compact system makes this discovery particularly exciting. It highlights the remarkable diversity of exoplanetary systems and strengthens the case for studying potentially habitable worlds around low-mass stars."
The twin spacecraft are part of the NASA-funded TRACERS mission, which will spend at least a year measuring plasma conditions in narrow regions of Earth's magnetic field known as polar cusps.
