Axiom-4 mission: Who are the crew members?
Shubhanshu Shukla is set to become the first Indian astronaut to travel to the International Space Station.
Joining him on the Axiom-4 mission are three other astronauts.
Leading the mission is Peggy Whitson, a former Nasa astronaut and now Director of Human Spaceflight at Axiom Space.
The two mission specialists are Tibor Kapu from Hungary and Slawosz Uznanski-Wisniewski from Poland. Both are project astronauts with the European Space Agency.
Here's a look at the crew:
Peggy Whitson
Whitson, who previously commanded Axiom Mission 2 (Ax-2), is the most experienced astronaut in American history.
She has completed three long-duration missions and spent a total of 665 days in space, more than any other American or woman astronaut globally.
With over 38 years of experience in space and science, she has worked with Nasa in various roles and now heads human spaceflight at Axiom Space.

During Ax-2, she became the first woman to command a private space mission. She was also the first woman to lead the ISS and remains the only woman to have done so twice. She also made history as Nasa's first non-military female chief of the Astronaut Office.

Across her three missions, she has performed 10 spacewalks, clocking over 60 hours, and carried out hundreds of experiments aboard the ISS.
She has made contributions to biology, biotechnology, physical and Earth sciences, and has also overseen numerous cargo missions bringing supplies and research material to the station.

Shubhanshu Shukla's journey to ISS
Shukla is the designated pilot for the Axiom-4 mission. He is one of the four astronauts preparing for India's first human spaceflight programme, Gaganyaan, which is scheduled for launch in the first half of 2027.
Originally from Lucknow, Shukla has served as a fighter pilot for over 16 years and has logged more than 2,000 hours of flying time.
As part of the mission, he will lead research focused on food and nutrition in space. These studies have been developed with the Indian Space Research Organisation (Isro) and the Department of Biotechnology (DBT), with support from Nasa.
Over the course of his aviation career, Shukla has flown various aircraft, including the Su-30MKI, MIG-21, MIG-29, Jaguar, and Hawk. He is a qualified fighter combat leader and an award-winning test pilot.
With this launch, Shukla becomes the first Indian astronaut to travel to space in more than forty years, after Rakesh Sharma's historic mission aboard a Soviet Soyuz spacecraft in 1984.
