China has successfully conducted its first controlled recovery of an orbital class reusable rocket booster during the maiden launch of the Long March 10B carrier rocket, marking a significant milestone in its reusable space technology.
Key Highlights
- Long March 10B successfully placed its payload into the designated orbit.
- After stage separation, the first stage booster returned safely and was captured on a sea based platform using a net capture system.
- This marks China’s first successful controlled recovery of an orbital class rocket booster.
- The achievement follows SpaceX, which became the first to recover an orbital class rocket booster in December 2015.
- Two previous Chinese attempts at vertical landing in December 2025 had failed.
What is a Reusable Launch Vehicle (RLV)?
- A launch vehicle designed to recover and reuse some or all of its components after launch.
- Typically, the first stage booster is recovered since it accounts for a major share of launch costs.
- Recovery methods include:
- Vertical landing on land or drone ships (SpaceX).
- Sea based platform recovery using net capture (Long March 10B).
- Reusability significantly lowers the cost of access to space.
Benefits of Reusable Rocket Technology
- Reduces launch costs through multiple reuse of boosters.
- Enables higher launch frequency.
- Improves commercial viability of space missions.
- Supports deep space exploration and satellite deployment.
- Reduces manufacturing time and resource consumption.
China’s Long March Rocket Family
- Developed by the China Academy of Launch Vehicle Technology (CALT).
- Serves as China’s primary family of orbital launch vehicles.
- Used for: Satellite launches. Human spaceflight missions. Lunar and deep space exploration.
- Long March 10 is being developed for China’s future crewed Moon missions.
India’s Reusable Launch Vehicle (RLV) Programme
- Developed by ISRO.
- Aims to create a fully reusable space transportation system.
- Key milestones:
- RLV-TD (Reusable Launch Vehicle Technology Demonstrator) first flew in 2016.
- LEX (Landing Experiment) successfully demonstrated autonomous runway landing in 2023.
- LEX-02 and LEX-03 further validated autonomous landing technologies.
- Intended to reduce launch costs and improve access to space.
[2018] With reference to India’s satellite launch vehicles, consider the following statements :
1.PSLVs launch satellites useful for Earth resources monitoring whereas GSLVs are designed mainly to launch communication satellites.
2.Satellites launched by PSLV appear to remain permanently fixed in the same position in the sky, as viewed from a particular location on Earth.
3.GSLV Mk III is a four-stage launch vehicle with the first and third stages using solid rocket motors, and the second and fourth stages using liquid rocket engines.
Which of the statements given above is/are correct?
[A] 1 only
[B] 2 and 3
[C] 1 and 2
[D] 3 only
