• Global interest in Moon mining has surged, with Helium-3 being a primary target for future lunar missions.
• The Ariane 6 has completed successful test flights, reaffirming its role as a versatile and reliable launch vehicle for various satellite constellations.
• Tunnel hood technology is being increasingly integrated into India’s Himalayan connectivity projects to improve reliability against natural disasters.

Key Facts and Data

• Helium-3 is abundant on the Moon due to solar wind bombardment but is extremely rare on Earth.
• Ariane 6 exists in two configurations, 62 and 64, to suit different payload requirements.
• Tunnel hoods serve as protective barriers against slope instabilities, which are common in young, geologically unstable mountain ranges like the Himalayas.
