"China demonstrates reusable rocket landing, intensifying global space competition"
Reusable Launch Vehicle (RLV)
rocket whose booster is recovered, refurbished, and reflown, cutting per-launch costs
Expendable Launch Vehicle (ELV)
single-use rocket; booster discarded and destroyed after each mission
The economics of space access have long been governed by a single constraint: expendable launch vehicles (ELVs) are discarded after a single use, making each mission prohibitively expensive. The first-stage booster — the largest, most engine-dense, and costliest segment — typically falls into the ocean or burns up on re-entry. The modern era of vertical-takeoff, vertical-landing (VTVL) reusability transformed this calculus by demonstrating that powered descent and propulsive landing could make booster recovery economically viable, dramatically reducing per-launch costs and enabling higher launch cadence.
The United States Space Shuttle (1981–2011) was an earlier, partially reusable system, but it did not achieve meaningful cost reductions — its operational costs per launch were, paradoxically, higher than many ELVs of the era. The commercial breakthrough came with SpaceX's Falcon 9, which pioneered VTVL reusability in the 2010s and demonstrated that a private-sector actor could outpace government programmes in pace of innovation. Subsequently, Blue Origin demonstrated similar capabilities with its New Shepard vehicle. These developments triggered a global race, with China, Japan, and India all pursuing reusable launch architectures suited to their respective industrial and strategic contexts.
India's own reusable launch programme is embedded within ISRO's indigenisation mandate and the IN-SPACe framework, which seeks to open space activities to private players. ISRO's RLV Technology Demonstrator (RLV-TD), nicknamed Pushpak, successfully demonstrated autonomous winged runway landing — not propulsive vertical landing — validating guidance, navigation, and control systems critical for future operational vehicles.
Reusable launch vehicles operate on the principle of powered descent and propulsive landing. After stage separation, the booster re-ignites its engines to perform a controlled deceleration, re-enters the atmosphere, and lands — either on a ground pad, a drone ship (floating offshore platform), or via a catch mechanism. Three distinct recovery architectures have now been demonstrated globally:
The net-catch architecture used by the Long March 10B is technically significant because it eliminates hydraulic landing legs entirely. …
Which one of the following statements best reflects the idea behind the "Fractional Orbital Bombardment System" often talked about in media?
Consider the following statements:
1.Ballistic missiles are jet-propelled at subsonic speeds throughout their flights, while cruise missiles are rocket-powered only in the initial phase of flight.
2.Agni-V is a medium-range supersonic cruise missile, while BrahMos is a solid-fuelled intercontinental ballistic missile.
Which of the statements given above is/are correct?
With reference to reusable launch vehicle (RLV) recovery architectures, consider the following pairs:
1.Leg-landing on drone ship — SpaceX Falcon 9
2.Mechanical-arm mid-air catch — China's Long March 10B
3.Net-catch via landing hooks — SpaceX Starship
Which of the pairs given above is/are correctly matched?
Which of the following statements about ISRO's RLV Technology Demonstrator 'Pushpak' is/are correct?
1.It uses vertical-takeoff, vertical-landing (VTVL) propulsive descent technology.
2.It demonstrated autonomous winged runway landing.
3.It is part of the IN-SPACe framework for private-sector space participation.
Assertion (A): China's Long March 10B rocket eliminates hydraulic landing legs in favour of landing hooks engaging a net.
Reason (R): Removing landing legs reduces the booster's structural mass, thereby increasing the payload margin available for orbital delivery.
Which of the following is correct?
