Frequently Asked Questions

What does mesosphere do?

The mesosphere acts as a vital transition layer in Earth's atmosphere between roughly 50 and 85 km altitude. It burns up incoming meteors, protects planetary surfaces, and plays an essential role in atmospheric circulation, ionospheric chemistry, and weather dynamics, making physical sampling of this boundary crucial for scientific climatology and defense research.
