What This Article Covers

1.Gaganyaan crew module re-enters at 7,500-8,000 m/s, dissipating 99% of kinetic energy as heat.

2.Remaining heat is intense enough to melt the module without a robust thermal protection system (TPS).

3.The article explains the ablative heat shield mechanism, a key technology for India's human spaceflight mission.

The Big Picture
Prelims · HighMains · Medium

Gaganyaan's crew module faces extreme heat (7,500-8,000 m/s) during re-entry. An ablative thermal protection system (TPS) is critical to prevent melting. This article explains the working of the TPS and why it is essential for the mission's success.

NavIC Constellation Drops to 3 Satellites, Fails to Provide Standalone Positioning: Govt Accepts

ISRO's NavIC system has lost its ability to provide independent navigation services because only 3 of its 7 satellites are operational, falling short of the minimum 4 required. The government has admitted this in Parliament, though timing services and emergency messaging continue. This raises concerns about India's space-based navigation self-reliance, but the armed forces mitigate risk by using NavIC as part of a multi-constellation GNSS that includes GPS, Galileo, and Glonass.
