The details of the mission, including the astronaut selection and launch timeframe, have not been disclosed yet.

The collaboration was highlighted in a fact sheet released by the White House on June 17, following a meeting of the U.S.-India initiative on Critical and Emerging Technology (iCET) held in New Delhi. The fact sheet mentioned the successful collaboration in various technology sectors and specifically highlighted their progress in securing a carrier for the first-ever joint effort between NASA and the Indian Space Research Organisation (ISRO) astronauts at the ISS.

Last year, the United States had announced plans to train Indian astronauts with the aim of conducting a joint mission to the ISS in 2024. Though the recent fact sheet did not reveal the carrier or the launch date for the mission, Eric Garcetti, U.S. ambassador to India, had earlier stated that the mission was expected to take place this year. However, a NASA spokesperson clarified that the mission details were still being finalized and further planning and training modules would be determined accordingly.

The most plausible scenario for an Indian astronaut to reach the ISS would be through a private astronaut mission, such as Axiom Space's Ax-4, scheduled for later this year. However, the crew for the Ax-4 mission and the training plans have not been disclosed by the company yet.

The fact sheet also mentioned the completion of a "Strategic Framework for Human Spaceflight Cooperation" between the two nations, without providing further details on the document. The joint statement released last year indicated that the framework would be finalized by the end of 2023, along with plans for advanced training for ISRO astronauts at the NASA Johnson Space Center.

In addition to the collaboration on human spaceflight, India and the United States are exploring opportunities for India's involvement in the Lunar Gateway Program and other joint avenues for collaboration in space technologies. The Lunar Gateway, a NASA-led project, currently involves Western partners on the ISS and the United Arab Emirates, which agreed earlier this year to develop an airlock module.

The joint statement also emphasized cooperation on defense space matters. India participated as an observer in the Global Sentinel space security exercise conducted by the U.S. Space Command in February and is expected to be a participant in next year's exercise. Furthermore, discussions on space defense cooperation took place during the Advanced Domains Defense Dialogue in May, where a space tabletop exercise was included. Notably, two Indian startups, 114ai and 3rdiTech, have partnered with the U.S. Space Force on space situational awareness technologies.

Additionally, the fact sheet highlighted the ongoing cooperation between NASA and ISRO on the NASA-ISRO Synthetic Aperture Radar (NISAR) Earth science mission. The launch of NISAR, originally scheduled for earlier this year, was postponed to make modifications to its large deployable antenna to safeguard it from higher-than-anticipated temperatures when stowed. No new launch date for NISAR has been announced yet.

The collaboration between the United States and India signifies a significant step forward in international space cooperation, paving the way for groundbreaking advancements in human spaceflight and exploration. As details regarding the joint space mission unfold, the global community eagerly awaits the realization of this historic endeavor.
