SpaceX Lands on Legs, China Uses a Net: How ISRO Plans to Bring Back Its Reusable Rocket

The race to develop reusable rockets has become one of the defining competitions in modern spaceflight, with leading space agencies and private companies exploring different ways to recover launch vehicles and reduce mission costs.

While SpaceX has popularized dramatic vertical landings using deployable landing legs, and China's commercial space firms are experimenting with giant recovery nets, Indian Space Research Organisation (ISRO) is charting its own course.

Rather than copying either approach, India's space agency is developing a reusable launch system that returns to Earth much like an aircraft.

SpaceX's Proven Formula

SpaceX revolutionized rocket recovery by enabling the Falcon 9 first-stage booster to reverse course after launch, reignite its engines and make a controlled vertical landing.

Using onboard guidance systems, grid fins and landing legs, the booster touches down either on land-based landing pads or autonomous drone ships stationed at sea.

The technology has allowed SpaceX to reuse boosters multiple times, dramatically reducing launch costs and increasing mission frequency.

China's Alternative: Catching Rockets

China is testing a different concept.

Instead of relying solely on landing legs, some Chinese aerospace companies are exploring recovery systems that involve giant suspended nets or other catching mechanisms to safely retrieve returning boosters.

The objective is to reduce structural weight by minimizing or eliminating landing hardware while simplifying recovery operations.

Although still under development, the concept reflects China's willingness to experiment with unconventional solutions.

ISRO's Aircraft-Like Landing

India's reusable launch ambitions center on the Reusable Launch Vehicle (RLV), a winged spacecraft designed to glide back through Earth's atmosphere.

Unlike Falcon 9, the ISRO vehicle is not expected to perform a powered vertical landing.

Instead, after re-entering the atmosphere, the spacecraft will use aerodynamic lift to descend toward a runway, eventually touching down like a conventional airplane.

This approach resembles NASA's retired Space Shuttle in terms of landing philosophy.

RLV-LEX Demonstrates Key Capability

ISRO achieved a significant milestone with its Reusable Launch Vehicle Landing Experiment (RLV-LEX).

During the test, a helicopter carried the winged prototype to high altitude before releasing it.

The vehicle autonomously navigated toward a runway, executed approach maneuvers and completed a successful landing without human intervention.

The demonstration validated critical guidance, navigation and autonomous landing technologies required for future reusable missions.

Why ISRO Chose This Route

Engineers believe runway landings offer several advantages for India's long-term reusable launch plans.

Because the vehicle generates lift during descent, it experiences lower landing loads than vertically landing boosters.

The design also supports easier inspection and refurbishment between missions.

However, developing a winged reusable vehicle introduces its own engineering challenges, particularly in thermal protection, flight control and atmospheric re-entry.

Reusability Is the Future

Reusable rockets have become essential for lowering the cost of access to space.

By recovering expensive hardware instead of discarding it after every mission, agencies can launch satellites, scientific payloads and human missions more economically.

The United States, China, Europe and India are all investing heavily in reusable technologies, though each is pursuing different engineering solutions.

India's Long-Term Vision

ISRO's reusable launch programme forms part of a broader strategy to improve launch efficiency while supporting ambitious future missions.

The technology could eventually play a key role in satellite deployment, cargo transport and India's long-term human spaceflight plans.

Although the system is still under development, each successful test moves ISRO closer to operational reusable launch capability.

Looking Ahead

SpaceX has demonstrated that vertical landings can transform commercial spaceflight, while China's experimental recovery methods showcase alternative thinking.

ISRO, meanwhile, is betting on a winged vehicle capable of returning home like an aircraft.

Each approach reflects different engineering priorities, but all share the same objective—making access to space cheaper, more sustainable and more frequent.
