Shubhanshu Shukla and his fellow crew members have resumed their final preparations, including pre-flight health checks, mission simulations, and technical briefings. They are expected to undergo the final phase of crew quarantine starting in the coming days to ensure health and safety standards are maintained prior to launch.

Significance for India

This mission holds particular importance for India as it represents one of the few times an Indian citizen will travel to space since Rakesh Sharma’s historic mission in 1984. While not part of India’s national space program, the involvement of an Indian astronaut in a NASA-backed, privately organized mission demonstrates India’s expanding footprint in the global space sector.

In addition, the mission underscores the growing trend of commercial spaceflight and the increasing participation of private companies in human space exploration.

What’s Next?

The Axiom-4 mission will involve a stay of approximately 10 to 14 days on the International Space Station, during which the crew will conduct scientific experiments, educational outreach, and research activities aligned with microgravity-based innovations.

If further updates emerge, especially concerning weather or technical constraints, Axiom Space and NASA have confirmed they will issue timely notifications.

For now, all eyes remain on June 19 as the launch date of this historic mission, which continues to capture attention not just in India, but across the global space community.

The era of disposable rockets is giving way to a new age of innovation: reusable rockets. These groundbreaking machines are changing the economics of space travel and paving the way for more frequent and affordable missions. From private space companies like SpaceX and Blue Origin to national agencies such as NASA, reusable rocket technology is fast becoming the cornerstone of modern aerospace engineering.

What Is a Resable Rocket ?

It is a type of launch vehicle that can be recovered and used for multiple missions. Unlike traditional rockets that burn up or fall into the ocean after launch, reusable rockets are designed to return safely to Earth, land vertically, and be refurbished for future use.

How Reusable Rockets Work

The technology behind reusable rockets is both complex and fascinating. Here’s a breakdown of how it works:

1. Launch Phase

Just like traditional rockets, reusable rockets lift off vertically using powerful engines fueled by liquid oxygen and kerosene or other propellants.

2. Stage Separation

After reaching a certain altitude, the rocket separates into stages. The upper stage continues to carry the payload into orbit, while the first stage, which contains most of the engines and fuel, prepares for return.

3. Controlled Descent

The first stage performs a series of engine burns to reduce speed and adjust trajectory. Small grid fins help steer the rocket through the atmosphere.

4. Landing

Using its engines for a final deceleration burn, the rocket lands vertically on a drone ship at sea or on a designated landing pad on land.

5. Refurbishment and Relaunch

Once recovered, the rocket undergoes inspections, minor repairs, and tests. If all systems check out, it’s ready for another flight—sometimes within weeks.
