What was the retro-package on John Glenn's space capsule designed to do?

The retro package on John Glenn's space capsule, known as Friendship 7, was designed to facilitate the spacecraft's re-entry into Earth's atmosphere. It contained retro rockets that would fire to slow the capsule's speed, allowing for a controlled descent. This system was crucial for ensuring that the capsule could safely return to Earth after completing its mission in orbit. Additionally, the retro package contributed to stabilizing the spacecraft during re-entry.
