The mission will launch from either the Kennedy Space Center’s LC-39A or Cape Canaveral Space Force Station’s SLC-40 launch facilities in Florida. It will use a Falcon 9 rocket to place the Crew Dragon spacecraft into low-Earth orbit (LEO). The mission will be the maiden flight of Crew Dragon C213, the fifth and potentially final Crew Dragon spacecraft.^[3][4] The capsule is still unnamed, traditionally the first crew to fly on it names it.

The flight is organized in collaboration with NASA and will be the fourth flight of Axiom Space after Axiom Mission 1, Axiom Mission 2, and Axiom Mission 3.^[5]

Ignis

The Ingis mission patch

Axiom Mission 4 will be the Poland's first manned mission to space since the fall of communism, as such POLSA and the ESA have created a specialized stand-alone technological and scientific mission for the Polish astronaut Sławosz Uznański-Wiśniewski named Ignis after the Latin word for fire. As part of Ignis Axiom Mission 4 will also carry a suite of experiments developed by Polish scientists and engineers, showcasing Poland’s contributions to international space research.^[6][7][8]

One of the payloads of the mission is a KP Labs Leopard Data Processing Unit an AI data processor to demonstrate how AI can process data in space thus making probes smaller and more efficient, as well as reducing the amount of ground infrastructure for space missions.^[9]

The Ingis mission has a specialized patch, separate from the Axiom Mission 4 patch, depicting an eagle in the Polish colors whose wings trace the contours of the Orla Perć mountain range with a stylized depiction of the Scutum constellation, a tribute to Johannes Hevelius over the missions name, with the 'i' being a depiction of the ISS.^[10]

Crew

The flight crew will include veteran astronaut Peggy Whitson, ISRO astronaut Shubhanshu Shukla, Polish astronaut Sławosz Uznański-Wiśniewski, and Hungarian astronaut Tibor Kapu.^[11]

Shubhanshu Shukla will be the first of India's astronaut corps to fly to space, gaining experience for India's own crewed spaceflight program.
