Gaganyaan Zero-G Training: Astronauts Train in ‘Vomit Comet’

India’s human spaceflight mission is progressing rapidly as astronauts undergo Gaganyaan Zero-G training, experiencing microgravity through specially designed aircraft flights.

The training is conducted using modified planes like Airbus A330 and IL-76, often referred to as “vomit comets,” which simulate the weightless environment of space.

How Zero-Gravity Flights Work

During Gaganyaan Zero-G training, the aircraft follows a parabolic flight path.

Each cycle involves:

• A steep climb
• A sudden descent

This creates a brief period of microgravity where astronauts float freely inside the cabin, similar to conditions in space.

These short bursts of weightlessness are repeated multiple times during a single session, allowing astronauts to adapt to the unfamiliar environment.

Training for Real Space Challenges

The zero-gravity exercises are a critical part of preparation for India’s first human space mission, led by Indian Space Research Organisation.

Astronauts are trained to:

• Move efficiently in microgravity
• Handle equipment in space conditions
• Maintain balance and coordination

This training ensures they are physically and mentally prepared for the challenges of space travel.

Astronaut Shubhanshu Shukla Shares Insights

Shubhanshu Shukla recently shared visuals and experiences from the training sessions, offering a rare behind-the-scenes look at the mission preparations.

The visuals highlight astronauts floating inside the aircraft, demonstrating how the simulation closely mimics real space conditions.

Why It’s Called the ‘Vomit Comet’

Zero-gravity aircraft are commonly nicknamed “vomit comets” due to the physical effects they can have on passengers.

The rapid changes in motion can cause:

• Motion sickness
• Disorientation
• Nausea

Despite these challenges, such training is essential to help astronauts adapt and perform effectively in space.

Gaganyaan Mission Gains Momentum

The Gaganyaan Zero-G training marks a significant milestone in India’s space journey.

The mission aims to send Indian astronauts into space, showcasing the country’s growing capabilities in human spaceflight.

With each phase of training, the astronauts are getting closer to being fully mission-ready.

India Steps Closer to Human Spaceflight

The preparation reflects India’s commitment to advancing its space programme and entering an elite group of nations capable of sending humans to space.

As training continues, the Gaganyaan mission is expected to play a key role in shaping the future of India’s space exploration efforts.
