How Gaganyaan’s thermal protection system will survive re-entry | Explained
Why does Gaganyaan need a thermal protection system? How does its ablative heat shield work?
Gaganyaan's thermal protection system (TPS) plays a critical role during the capsule's return to Earth, safeguarding it from the intense heat generated by atmospheric friction. As the spacecraft re-enters our planet's atmosphere, it plummets at speeds of 7,500-8,000 meters per second, causing over 99% of its kinetic energy to convert into heat energy.
To prevent the module from melting, a robust TPS is essential. This protective layer must withstand the extreme temperatures, ensuring the safety of the astronauts aboard the Gaganyaan crew module.
