આ શા માટે મહત્વનું છે

The development of fully reusable, heavy-lift rockets like Starship significantly reduces the cost of accessing space and deploying mega-constellations. This is highly relevant for UPSC aspirants as it demonstrates the cutting-edge of space technology, the increasing dominance of private sector players in space exploration, and the technological architecture underpinning global initiatives like the Artemis Accords, which India has signed.

સારાંશ

SpaceX achieved a major milestone in space exploration as its Starship rocket—the largest and most powerful launch vehicle ever built—successfully completed its 13th test flight, ending with a controlled, intact splashdown in the Indian Ocean. During the mission, it deployed 20 Starlink satellites into orbit. While the Super Heavy booster failed to return safely due to an engine restart issue, the overall success of the Starship upper stage is a critical step forward. This development is vital for deep-space exploration, particularly NASA's Artemis III lunar mission, and highlights the transformative role of fully reusable launch vehicles in making space travel more affordable.

મુખ્ય મુદ્દા

  • SpaceX's 407-foot Starship, the world's most powerful rocket, successfully completed its 13th test flight, splashing down intact in the Indian Ocean.
  • The flight successfully deployed 20 next-generation Starlink satellites into low Earth orbit.
  • The Super Heavy booster experienced a technical glitch during its return burn, crashing into the Gulf of Mexico instead of achieving a controlled catch.
  • NASA is relying on a modified Starship to serve as the lunar lander for the upcoming Artemis III mission to return humans to the Moon.
  • The successful test of this fully reusable heavy-lift vehicle brings SpaceX closer to its goal of drastically reducing spaceflight costs and enabling crewed missions to Mars.

India's amended space FDI policy permits 100% foreign investment under the automatic route across all segments, including launch vehicles.

Launch vehicles and spaceports only allow up to 49% FDI under the automatic route; beyond 49% requires government approval.

સંલગ્ન સ્થિર ખ્યાલો

Science & Technology (Space)

What is the Outer Space Treaty (1967) and its basic mandates?

  • No Sovereignty: Prohibits national appropriation of outer space, including the Moon, by claim of sovereignty, use, occupation, or any other means.
  • Peaceful Use: Bans weapons of mass destruction in orbit and celestial bodies, dedicating space exploration solely to peaceful purposes.
Science & Technology (Propulsion)

How do Cryogenic and Semi-Cryogenic engine propellants differ?

  • Cryogenic Systems: Use liquid hydrogen (-253°C) as fuel and liquid oxygen (-183°C) as oxidizer, requiring complex, ultra-cold storage.
  • Semi-Cryogenic Systems: Use refined kerosene or methane instead of liquid hydrogen, resulting in higher propellant density and easier storage at ambient temperatures.

આંતર-વિષય પેટર્ન

  • Space FDI + Strategic Autonomy

    Liberalizing private space sector investments under automatic FDI routes creates tensions between accelerating technology transfer and safeguarding indigenous security-sensitive space defense capabilities.

  • Mega-constellations + Space debris governance

    Rapid deployment of massive satellite constellations like Starlink amplifies the risk of Kessler syndrome, testing the limits of non-binding UN space debris mitigation guidelines.

Project Soorya (NGLV) and private-led space commercialization paradigms are likely to be tested via a multi-statement question in Prelims 2026.
