Shubhanshu Shukla Performs Zero-Gravity Tricks With Water On ISS

Astronaut Shubhanshu Shukla, pilot of the Axiom-4 mission, recently conducted a fascinating zero-gravity experiment on board the International Space Station (ISS) to demonstrate how the laws of physics change in space. The experiment, part of Axiom Space's broader outreach and scientific goals, showcased the unusual behavior of water in microgravity.

During the demonstration, Shukla used surface tension to create a floating water bubble, humorously referring to himself as a “water bender” while manipulating the sphere of water in mid-air.

Veteran astronaut Peggy Whitson, who commanded the mission, added another layer to the demonstration by gently pressing a plastic bag into the water sphere. The bubble, reacting like a magnet, clung to the bag and distorted light—visibly acting like a lens due to surface tension effects in microgravity.

The Axiom-4 crew—comprising Shukla, Whitson, and mission specialists Slawosz Uznanski-Wisniewski from Poland and Tibor Kapu from Hungary—spent 18 days aboard the ISS. Their return journey to Earth began on Monday evening, marking the conclusion of a mission that blended scientific research, public outreach, and STEM education.

Reflecting on the experience, Shukla shared how mesmerized he was by the view of Earth from space:

"I try to savour every moment I get—just sitting by the window and looking down. It's the most beautiful view I've seen."

Whitson, discussing the mission’s end, emphasized the dual focus on rigorous science and educational engagement, with outreach activities spanning India, Hungary, and Poland.

As they prepare to return to Earth, the astronauts spoke candidly about the challenges of re-entry. Whitson, with her past experience, quipped:

“Gravity really does suck.”

Shukla, who experienced some space motion sickness during ascent, hopes to fare better during the descent.

The Axiom-4 mission took off on June 25, launched aboard a Falcon 9 rocket from Florida. In just 10 minutes of their live interaction, the astronauts estimated having traveled nearly 2,900 miles, showcasing the speed and scale of life in low Earth orbit.
